Acquisition of a 3.5 acre parcel for Public Works needs. Mayor Jabbour and the City Administrator met with the Orono Schools Superintendent and Assistant Superintendent to explain the City ’s Public Works needs and the proposed land acquisition. The Superintendent will forward the City ’s request to the School District’s Facilities Committee. 2. School District property east of the Lee Carlson youth baseball fields. The Orono Schools Superintendent indicated the school was entering discussions with Bancor, the developers of the 58 acres east of the school property and west of Willow Drive, regarding the acquisition of the property east of the Lee Carlson fields by Bancor. There was some discussion regarding whether the City of Orono would be interested in acquiring that property. In order for the City to make a decision regarding that property, the City should answer the following questions: a. Is this property a priority property to be acquired for park needs? b. What park needs would this property meet? c. Are the park needs that would be met by this property high prioriU' needs? If the Council determines that the City may want to pursue this property, the City should determine whether it would be bidding against Bancor for the property. To:Mayor and Council Planning Commission Members Ron Moorse, City Administrator From:Mike Gaffron, Senior Planning Coordinator Date:January' 21. 2000 Subject:Monday January 24 Work Session - Comprehensive Plan Discussion Topic: Review of -Draft Housing Plan -Draft Environmental Protection Plan -Rough Draft Transportation Plan The Housing Plan (CPM PART 3C) was discussed conceptually in September; the attached draft reflects those discussions. One possible topic for further discussion is how will Orono ensure that the Hackberrv Hill area MUSA additions will be reserved for replacement of Lone Lake homes lost due to Highway 12 acquisitions , and not developed with $300,000-400,000 homes on 1/3 acre lots. The Environmental Protection Plan (CMP PART 3A) has been somewhat updated from the 1980 version, and still contains much of the 1980 background information. Some of it may seem tedious and perhaps redundant; but it also f .o tremendous value in documenting the basis for Orono ’s development philosophy. The Transportation Plan (CMP PART 4A) is at present only ‘half-baked ’, in that may of its sections have not yet been updated. But there are a number of issues to discuss Monday, such as: - How does Council wish to address the Bonestroo Co. Rd. 15 traffic study in the CMP? - Policy issues in relation to public vs. private roads... - Future vision for the e.xisting Highway 12 corridor... - Future light rail transit corridors - giving up on Dakota Rail in favor of trail? - Pick another issue of your choice!

The presence and character of these attractive amenities has been a major factor affecting the original settlement and subsequent development of the City. The protection and preser\ation of these resources as part of our local heritage, and in our citizens' continuing vital interest, is the foremost goal of this Community Management Plan. Lake Minnetonka is the single most significant natural feature in Orono and in the entire western part of Hennepin Countj*. Lake Minnetonka, as shown on Map Figure No._, is actually a series of separate lakes or "bays" interconnected by narrows or channels. Some bays are up to 90 feet deep while other areas are extremely sliallow. Lake Minnetonka outlets at Gray's Bay in the City of Minnetonka, into Minnehaha Creek and eventually into the Mississippi River. Lake Minnetonka is the tenth largest lake in Minnesota. Lake Minnetonka has a surface area of approximately 14.310 acres (5+t5 22.4 square miles) and a capacity of 400,000 acre feet of water at the normal lake elevation of 929.4 ft. MSL. The total watershed is 123 square miles in area which includes 71 square miles of dr\’ land, 22 square miles of marshland and 7 square miles ot other water bodies. With its many bays and channels. Lake Minnetonka has over 100 approximately 130 miles of shoreline. Lake Minnetonka has substuntial public value as a recreational asset, as an environmental resource and as a setting for private residential development. Lake Minnetonka's closeness to Minneapolis combined with its size have long given it a unique status among the lakes in Minnesota. In the 1880's. Minnetonka became a nationallv known resort area and has been a favorite locale for summer and suburban homes for generations. From the viewpoint of the fisherman, the lower lake resembles the more nonliem waters of the state, whereas the upper lake and its bays resemble southern Minnesota waters. The large size of the lower lake is a major attraction for sailboaters while the \ ariety of bays, channels and water routes ofler attraction to the casual boater. I I I 1 1 1 1 I 1 1 :i mi I CMP 3A - 1 I I I n I h FIGURE___ Map of Lake Minnetonka with City Boundaries • * t t i: i: i: i; L B CMP 3A - 2 Lake Minnetonka is dependent upon watershed runofT for all replenishment. Lake Minnetonka is not fed by any spring or river inlet. All water is received from precipitation falling within the immediate watershed. Most of this water enters the Lake by direct runoff through a series of five major streams and their associated lakes, marshland and sub-watersheds. Since the level of the Lake is generally below the level of the ground water in the glacial deposits of the surrounding area, some additional replenishment o curs from underground seepage, principally from the many wetlands and marshy ponding areas along the shoreline. Lake Minnetonka's ecology makes it easily susceptible to pollution hazards. The combination of a single-source local water supply, relatively small watershed area, many channel restrictions between separate bays, and a single outlet, have resulted in Lake Minnetonka having an extremely long 25-year flush out period for complete water change. This is second only to Lake Michigan in the region. The hazard is that once pollutants enter the Lake, they tend to remain for a long time and they are not easily diluted. Lake Minnetonka has historically suffered from t^vo problems which directly affect its environmental health and its value as a public amenity. One problem w hich has been worsening with urbanization trends is a deterioration in water quality caused by eutrophication. Eutrophication is the aging process by w hich natural waters are enriched with nutrients that may stimulate excessive plant growth The plants may be floating algae, attached algae, or rooted weeds. Eutrophication may occur naturally, as sediments accumulate in lake basins over geologic time or it may be induced artificially as a result of human activities, as in Lake Minnetonka. Much of Lake Minnetonka has become more eutrophic during the last several decades the past century, but sedimentation has been negligible. Instead, the accelerated eutrophication of the Lake, w hich is due to increased inputs of nutrient elements, particularly phosphorus and nitrogen, is evidenced by the increased grjwih of algae and weeds. The other problem is hydrologic instability. Because the lake level is dependent upon precipitation, w ide ranges in water elevation have occurred over the years. During the 1930's. a general drought left the lake below normal level for 11 years with a maximum decline of more than 6 feet. This low water condition caused the con:.truction of deep wells for water augmentation and discussions about possible diversion oftheCrow'River. A somew hat lesser drought durinu the late 1980's attain raised concern about the instability of lake levels, vet the lake recovered from a 4- foot drop in just two years without autimentation. I I I |Ni»< t CMP 3A - 3 I I I r i I i' »• M M M H M If I I i; In recent years, however, more urbanization has increased the amounts of direct storm water runoff resulting in high water levels and in some cases flooding problems for low-lying properties. Upland water retention an d a controllable outlet at Gray's Day hax T- now become priorities of the Minnehaha Creek Wate rshed District.(?) Management of runoff and protection of water quality have now become primary objectives of the Minnehaha Creek Watershed District. The problems of Lake Minnetonka have been were intensively studied by many agencies over the las t twenty yea rs in the I960*s and I970*s . These agencies included the Minnesota Pollution Control Agency, the Minnesota Department of Natural Resources, the Metropolitan Council, the Minnehaha Creek Watershed District, the Lake Minnetonka Conservation District and the City of Orono. The major publications addressing Minnetonka's problems and which formed the basis for the goals and policies of this Orono's 1980 CMP and this update of it, are as follows: 1969 Overall Plan for Water Management; MCWD 1971 "Harza Study", A Program for Preserving the Quality of Lake Minnetonka; LMCD & Mn. PCA 1973 Shoreland Management Regulations of the Mn. DNR 1973 Stormwater Impact Investigation for the Metropolitan Council 1974 Surface Water Management Plan for the City of Orono 1979 208 Water Quality Management Plan for the Metropolitan Council Orono's special involvement with Lake Minnetonka is based upon the real concerns of our affected citizens and our intimate and important impact on the total lake environment. While Orono's population is not as large as that of other municipalities in the Lake Minnetonka Watershed, Orono docs have the largest land area and potential environmental impact of any local unit of government. Orono is the largest city totally within the Watershed. Orono has one fifth of the total diy land in the watershed, one quarter of the vvetlands and one third of the lake surface. Orono includes 40% of Lake Minnetonka's total shoreline. Over 30% of the total Watershed's surface runoff flows through or from Orono on its way to the Lake. (Confirm all the above statistics - see below) CMP 3A - 4 14.300 acres water surface (22.4 square miles) (MCWD PLAN SEC 4 P16) Drains an area of 123 square miles, 22.4 of which it occupies (IBID P62) 123-22.4=100.6 square miles drain into Lake Minnetonka Orono land area is 10,200 acres or 16 sq. miles e.xcluding lakes, about 16.5 square miles including City lakes but not Mtka; 16.5 / 100.6 = .164 =1/6 of watershed is from Orono 131 miles of shoreline (IBID PI 6) 110 miles of shoreline (IBID P63) ?!?!?! Orono’s portion is 40 miles or 31% (36%) of shoreline (City measurement by MPG) -need to work on this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!- I No other community has the same potential as Orono for affecting Lake Minnetonka's water quality or water quantity, therefore, no other single community has as heavy a responsibility for careful protection of this general resource as does Orono. Other significant lakes in Orono include Long Lake, Mooney Lake, Lydiard Lake, Lake Classen and Dickey's Lake. Lydiard Lake and Dickey's Lake drain into Long Lake which in turn flows into Long Lake Creek and eventually Tanager Lake (bay) of Lake Minnetonka. Lake Classen drains into Stubbs Bay of Lake Minnetonka and Mooney Lake drains through Plymouth and Wayzata before discharging into Wayzata Bay of Lake Minnetonka.

No Only minimal residential development encroaches on its pastoral setting. Dickey's Lake is centered in open fields has become surrounded bv low density residential development over the past 20 years but its steep slopes and low elevation have preclud ed any extensive d evelopment or encroachment. Lake Classen, in Orono's rural area, is surrounded by orchards and farm fields with a handfull of homes overlooking its waters. The Orono School District maintains a nature study area and waterfowl ponds on Classen's east shore. Mooney Lake's shore is essentially relatively undeveloped in Orono and Medina, but the lake has received growing pressures from urbanization in Plymouth, including usage conflicts, elevation concerns due to lack of a natural outlet, and urban storm water pollution inflow. Long Lake is the largest and most actively used lake in Orono other than Minnetonka. The east and west shores have been developed at rural residential densities. The north shore has mixed rural residential areas and one more dense housing cluster dating from the 1930's. The south shore is bordered by the City of Long Lake and is urbanized to the same degree as much of Lake Minnetonka. Long Lake has experienced stonn water problems and has recently had as well as increased usage pressures resulting from over use of power boats and personal watercraft, and plans for multiple family residen ces and d ocks on the south shorty The Minnehaha Creek Watershed District in the late 1990's implemented a multi­ faceted stormwater improvement project for Lomz Lake includine construction of water quality retention ponds in the two main tributaries feedinu the lake, and alum treatments within the lake basin for phosphorus control. The second most significant and most universal natural amenity in Orono are the many wetlands and marshlands comprising Lake Minnetonka's upland drainage system. Orono's six sq uare miles 1600 acres of marshland and wetlands comprise fully one-third sixth of the City's land area. Map No.__indicates how the marshland and drainageways are scattered throughout the City. CMP 3A - 6 I FIGURE WETLANDS, DRAINAGEWAYS AND FLOODPLAINS These natural ponding areas ser\e an integral function within the natural ecological system of Lake Minnetonka. The "Harza Study" includes quantitative data identifying how the wetland soils easily retain phosphorus, and how marsh plants take up and incorporate large amounts of nitrogen and phosphorus into their growing tissue. Thus, the marshlands are the primary pollution filters for Lake Minnetonka's surface water runoff. Since marshes and small lakes in the watershed aggregate nearly as much area as the main body of Lake Minnetonka, their potential for supplying water to the subsurface formations is appreciable. In addition, marshes provide a diversity in the kinds of open space available within the region. They provide a habitat which is uniquely suited for certain birds and mammals. They can be utilized to provide storage of storm runoff with minimal disruption to their function as a habitat for wildlife and their ability to reduce the phosphorus input to the lake. The historic problem has been that burgeoning urbanization has adversely affected the existence and the function of wetlands. The Harza Study showed that typical suburban forms of urbanization will lead to the pollution of the watershed and Lake Minnetonka because of the increased phosphorus load which would be in the surface water runoff. CMP 3A - 7 I I I • I » « » I { t • ¥ * I I I * »t *■ t i • M M M It is a documented fact that the amount of phosphorus increases with urbanization. When urban development occurs, the function of the natural drainageways and filtration system is adversely affected in three ways: The speed and quantity of the storm water runoff are increased as the absorption ability of the land is eliminated with hardcover (houses, driveways, roads, etc.). This increase in the speed and quantit>' of storm water runoff causes the third adverse effect, which is the increase of the amount of nutrients which are contained in the storm water runoff which now has less time in the natural marsh filtration system to be purified before entering the lake. Nutrients contained in dying vegetation, lawn fertilizers, and from other urban sources are discharged into the lake faster and in greater quantities as the level of urbanization increases. The Hickok report entitled "Storm Water Impact Investigation for the Metropolitan Council", November, 1972, revised February, 1973, shows showed that in an urbanized area, as much as 3.68 pounds of phosphorus per acre is generated versus 0.3 pounds per acre of discharge from a two acre minimum lot size zone as exists in rural Orono. Orono's Surface Water Management Plan of 1974, also done by Hickok, documented that Orono's existing rural wetlands could assimilate the rural phosphorus load but would be insufficient to handle an urban phosphorus load. In fact, Orono's existing urban wetlands were already overloaded. Thus, if rural Orono were to become urbanized, even at relatively low urban densities, phosphorus loading of Lake Minnetonka would increase to dangerous levels. Orono. however, must not rely solely on the ability of the natural filtration system of the marshes and drainageways to purify storm water so ncccssar>' for the preservation of Lake Minnetonka. Several recent studies, one of which is by the University of Wisconsin entitled "Effect of Marshes on Water Quality", concludes that because of our freezing winter temperatures much of the filtration value of the natural marsh process is lost during the annual spring snow melt. It is commonly known that it is the cellular structure of aquatic vegetation that assimilates nutrients from storm water running through marshland in the summer. These studies point out, however, that this cellular structure freezes and ruptures during the winter, thereby releasing all the stored-up nutrients to flush-out into the lake in one mass loading during the first prolonged thaw. There tore. Orono is advised to keep the basic level of urbanization low. particularly in the rural service area, so as to minimize the adverse effect on Lake Minnetonka it this spring thaw thcor>‘ is in time proven to be valid. CMP 3A - 8 c Man-made Stormwater Ponding While Qrono's newlv-adopted Surface Water Manauement Plan places a significant emphasis on preservation of wetlands, it also provides for the establishment of su pplementary stomiwater management ponds to help counteract the impacts of development within the watershed. The City of Orono in October 1993 amended the 1980 Comprehensive Plan bv adoption of the use of NURP fNational Urban Runoff Program) standards for the design of man-made stormwater ponds. This requirement has not vet been adopted into the zoning code, but the Citv has been requiring NURP ponds for stormwater management within new developments in accordance with standards of the Minnehaha Creek Watershed District. William W. Walker. Jr., an environmental engineer from Concord. Massachusens. is credited with the 'model* which evaluated the design criteria for NURP ponds. He used phosphorus retention data from 60 reser\ oirs and compared it to phosphorus retention data for a number of ponds and lakes, including manv in the Twin Cities area. He concluded that his 'model' could be used to predict the phosphorus retention capability of urban lakes and wet detention basins based on a number of design parameters. Conversely, it is then possible to design ponds which should retain a given amount of phosphorus. Phosphorus inflow from a watershed to a basin is reasonably predictable given the characteristics of the watershed. NURP pond design criteria is primarily based on the removal of suspended particles such as sand, silt, etc. Secondar\ design criteria enhance the capability of NURP ponds to remove other pollutants such as trace metals, hydrocarbons, nutrients (such as phosphorus) and pesticides. Phosphorus is rnainlv removed through biological uptake in algae and aquatic plants. When the algae die, the nutrients fall to the bottom of the pond and become part of the sediments. Ponds in the Twin Cities area designed according to NURP standards have total phosphorus removal eftlcicncies of 47 to 68 percent according to Walker. Possibilities for improving this include (1) increasing mean pond depth: (2) promoting infiltration: (3) promoting plug flowconditionsti.e. multiple cell ponds): (4) applying chemicals to precipitate out the orthophosphorus (alum treatments): (5) encouraging growth of certain aquatic plants: and (6) design of outlet structure to provide extended detention of large runoff events. Whether each of these enhancements can or should be incorporated is dependent on the desired level of control and other site specific conditions. CMP3A-9 I I I 1 1 1 t < ► < - I I I I r r I I f I t > 1 I • M M H M M M H i; L B Constructed wetlands have potential benefits as well as drawbacks. Additionally, the cost of constructing stormwater ponds and storm sewer systems is enormous compared to the cost of wetland preservation. New nutrient management technologies such as NURP ponds or alum treatments will give Orono an added tool to manage runoff from rural densities, but Orono cannot and will not rely solely on man-made systems for preserving water quality. Orono's land forms are highly varied as the result of four separate glacial scourings. Surface features include islands, peninsulas, narrow land bridges, the lakes, bays and marshes, and a few shallow outwash basins. The highest elevations range from about 1060 feet above mean sea level in the northern part of the City down to the normal water level of Lake Minnetonka at elevation 929.4 MSL. Steep slopes and numerous glacial depressions add interest to the City's landscape but cause developmental limitations. The soils in the City of Orono originated from drift materials deposited by meltwaters of the glaciers. Due to the range in type and location of deposited materials, the composition of the soils are complex and highly varied. Generally, the soil types consist primarily of clay materials on the uplands and organic, wet materials in the lowland areas. Consequently, the ability of each soil type to adequately accommodate development varies considerably in Orono. Careful examination of each site is needed to determine the most appropriate land use for individual properties. FIGURE SOILS MAP CMP3A- 10 Orono's native vegetation is as varied as its land forms. Orono and Lake Minnetonka are at the intersection of t\\^o very different Minnesota landscapes. Northern Orono, and many areas along Minnetonka's shore, contain vestiges of Minnesota's Big Woods with hardwood forests of Oak, Maple. Elm, and Basswood. Much of these have been thinned into scattered stands, as shown on Map No. 5, but major forests remain in north central and north east Orono, especially around Lydiard Lake and in the Mn. DNR’s Wolsfeld Woods and Wood Rill nature areas. In addition, 100 year old settlements have by now added mature stands of various evergreens and other decorative trees and shrubs. Western Orono, on the other hand, shows traces of Minnesota's once vast prairie. Years of farming have caused loss of prairie grasses and the artificial growth of windbreak woods, but open vistas still stretch westward from North Arm Bay. Throughout Orono, the many drainage areas and marshlands support a bountiful variety of wetland vegetation ranging from grasses, bulrushes and cattails to sumac and willow. The sum effect of these varied landscapes is a seasonal variety of color and an abundant habitat for wildlife including deer, fo.\. racoon and beaver, ducks, grouse, pheasants and innumerable species of smaller birds and animals. Orono's ground water supplies are abundant. Orono enjoys the same abundant ground water resources from the Twin Cities artesian basin as does most of the metropolitan area. In addition, our generally heavy' clay soil layers near the surface have protected the ground waters from surface pollution. Most areas of the City have had no difficulty obtaining potable water supplies drawn from the Jordan aquifer with wells ranging in depth from 75 to 200 feet. Only occasional wells have had to go deeper. The most noticeable ground water condition in the City is also caused by the same heavy clay soil layer which in many cases traps a layer of ground water very near to the surface. Especially near the lakeshore or any of the w etlands, wet organic soils often have perched water tables within three feet of the surface. 1 hese areas present severe restrictions on development but are scattered and localized such that individual properties often contain diy soil areas as well as wetter areas.

FLOOD PLAIN ANH STORM WATER CONSIDERATION S SURFACE WATER MANAGEMENT Orono’s many miles of shoreline are especially sensitive to misuse or overdevelopment. As the interface between land and water, the shoreline is ever changing. Shorelines are subject to continual erosion by wave action, ice buildup or unstable soil conditions. Droughts dry out vegetation and heavy rains or snow melt cause land slippage. On top of these natural pressures, man is drawn to the lake and the shoreline often becomes his battleground with nature. Lake access often means active use and construction of buildings and structures causing unnatural soil loadings, vegetation removal, and land alteration. Exposed soil becomes more subject to erosion and man-made hardcover increases direct runoff quantity and speed. Power boats increase wave action and, more damaging, stir up the lake bottom causing release of nutrients and increased turbidity. The impact, of course, is a degradation of water quality, impaired lake access and a change in the natural aesthetics which drew people to the shore in the first place. Legal considerations become entangled when lot descriptions conflict or become inconsistent due to changing water levels or shoreline locations. Therefore, planning considerations must recognize the desirability of human interaction with the lake while at the same time providing for protection of nature’s sensitively balanced shoreline ecology. Flood protection and floodplain management arc extremely important to a community' as closely associated with water resources as is Orono. Orono has no river system and therefore has no potential for swift, destructive floods in the typical sense. But general highwater conditions have the potential of affecting many properties by slowly rising water levels, shoreline destruction and high water tables. Most critical are those residences built on low-lying peninsulas such as Baldur Park, where a combination of high water levels and wave action caused by powerboats or high winds mav cause severe shoreline erosion. In addition. Hooding of upstream marshes may tend to cause localized backups or drainageway overloads. Orono has participated in the National Flood Insurance Program and has therein undertaken detailed studies of fiood-prone areas. Very few structures are actually affected but care is necessaiy to ensure no luture flood plain encroachment and no future loss of natural ponding areas which would result in higher water levels elsewhere. The general trend seems to be potential for increasing high water problems as urbanization spreads in other areas of the watershed thereby reducing natural ground water assimilative capacity, eliminating ponding areas and increasing CMP3A- 12 I storm water runoff quantities and speed. Therefore, Orono will preserve its wetlands as much as possible to alleviate downstream flooding. Management of storm water runoff is essential for protection of the water quality of Lake Minnetonka, for preservation of the natural wildlife habitat of the marshlands, and for protection against flooding and flood damage. The discussions above about Lake Minnetonka's water source, about wetlands function, shoreline protection and flood prevention all have a common connection to storm water management. The following sections are excerpts and highlights of the pertinent studies refereneed above: The Metropolitan Council's 208 Water Qualitv' Management Plan (1979) explained storm water pollution potential as follows: ''Background The problem of urban storm water runoff and the variable pollutants it carries has received an increasing amount of national attention in the past five years, largely because the contribution of unrecorded sources to water degradation had previously not been assessed. Literally hundreds of millions of dollars of pollution abatement funds are at stake, requiring careful allocation decisions. The primary water quality problems occurring as a result of urban runoff are caused by accumulation of pollutants and/or by short, intense 'shock loads' that result in immediate water quality effects. National studies are showing repeatedly that urb^n nonpoint inputs are a significant part of total water pollution loading. They contribute a load of pollutants equivalent or greater in some parameters than those released annually by municipal and industrial point dischargers (this has been locally confirmed by the "Harza Study" as being particularly relevant to Lake Minnetonka). Urban Stormwater Pollutants and Pollution Process The primaiy' pollutants moved by urban stomnvater are sediment, oxygen ­ demanding substances, nutrients, heavy metals, bacteria, chlorides from road salt, oil and grease, pesticides and poisonous compounds called polychlor ­ inated biphenyls (PCB's). Sediment from urban runoff merits primaiy attention both as a pollutant itself, and because of the tendency of some metals, nutrients and pesticides to adsorb onto fine soil or organic particles under certain conditions. Urban stormwater quality has sediment concentrations generally far greater CMP3A- 13 I I I I I I t I t f 1 t I • I t < » < * % I I I I k' * r i: i: K I than those of raw sewage, with predominant sources of sediment being erosion, atmospheric fallout and vehicular deposition. The detrimental effects of sediment include decreased light penetration, settling on lake or stream bottoms, transport of adhered pollutants, clogging of fish gills and decreased aesthetics. In general, urbanization will increase sediment loads, with areas of rapid development contributing the largest loads, but with fully developed areas also contributing large sediment volumes. Oxygen-demanding substances introduced by urban runoff threaten receiving water bodies with oxygen depletion resulting from biological and chemical degradation of oxidizable material. Oxygen demand is best represented through chemical oxygen demand (COD), but biochemical o,xygen demand (BOD) has historically been used as the most convenient means of reporting demand. BOD and COD concentrations occurring in stormwater runoff are approximately equal to those of secondary treatment effluent. The degree to which oxygen is lost as a result of this demand depends upon the amount of degradable material in the stormwater, benthic oxygen demands and the physical nature of flow in the receiving water body. Nutrient (nitrogen and phosphorus) input resulting from urban runoff is critical, since it becomes a contributing factor in eutrophication of downstream inactive waters. Nutrient input levels are generally less than inputs from municipal treatment sources, but nevertheless are significant to the total water quality condition. Phosphorus input to water bodies, particularly lakes, has in most cases been found to be the limiting element in determining algal productivity. Nutrient character in the stomi water runoff is highly dependent upon oxygen conditions. pH and physical conditions such as sediment and organic content in the water. Toxic hca\y metal loading from urban runoff merits attention as a potential nondegradable aid to stream deterioration. Metals are capable of reaching critical levels in quiet areas where they are able to accumulate in bottom sediments. Loading of heaNy metals during a storm contributes a signi ficant portion of the entire load to urban streams. Other constituents of urban runoff of concern, but of variable severity, include bacteria, chlorides (C1) from road salt, oil and grease, pesticides and PCB’s. These pollutants can be locally severe depending upon receiving water conditions and proximity to source areas. The major identified sources of urban stormwater pollution include: vehicular and industrial emissions and leakages, combined sewer overflows, skid control grit and deicing salts, street and construction litter, vegetation and animal droppings, improperly applied pesticides, atmospheric fallout and CMP 3A - 14 precipitation and urban erosion. The largest inputs of urban pollutants within a developed area come from industrial land uses, with commercial and high density residential uses following for most pollutants. Once pollutants are present on the urban surface, how they are moved about, either suspended in the water or in solution, becomes very important for the purpose of controlling them. Characteristically, an urban runoff event consists of the washing-off of accumulated debris from a parking lot. rooftop, street, etc., rapidly enough to move sand. grit, leaves and the like and dissolve the soluble chemicals. Extreme stress on the assimilative ability of the receiving water body is generally caused by an increase in both pollutant concentration and water runoff volume as the storm begins and overcomes normal watershed depression storage. The phenomenon of highest concentration during an event occurring on the rising limit of a hydrograph (runoff versus time) followed by gradual tapering-off is commonly called 'first flush’. The spring thaw of snow and ice can have an impact as great or greater than rain. Pollutants trapped by ice and snow are released together with the melt-water to produce a flush effect when temperatures rise enough to melt significant amounts of ice and snow. Other factors affecting pollutant migration include the storm pattern; physical factors such as soil type, land slope, and type of vegetation ground cover; infiltration into drainage systems; and amount of temporary storage available in the watershed. The worst time for an urban stormwater runoff to occur is during a period of low flow, high temperature and low wind, when design loads for point source inputs have not taken into account nonpoint inputs. These conditions overstress the ability of the stream or lake to assimilate the pollutants. Pollutants behave in various ways during stormwater runoff events. A typical storm would contribute extremely variable amounts of sediment. The laigest amount of sediment per volume of runoff w ould follow a first flush behavior, that is it would correspond w ith the greatest flow of water and then diminish. Associated with, and often adhered to this sediment are several harmful pollutants, including metals, nutrients, bacteria, pesticides, and PCB’s. Pollutants that adsorb to sediment generally tend to adsorb to the fine fraction, thus increasing mobility and management difficulties. The question of scale between individual runoff parameters becomes important in analyzing the effects of urban runoff. For pollutants such as COD and bacteria, the immediate areas downstream must be considered critical soon after an event. Pollutants such as metals and nutrients, how ever, migrate far downstream and have long-lasting effects." I I I 1 1 I 1 n fc-» CMP3A- 15 I I I r r [ r r r \ I I I -M The 208 Study concluded that urban stormwater runoff pollution is potentially a significant portion of total annual loading for the Metropolitan Area. Further water pollution abatement programs must consider this source of pollutant input and change to a balanced approach from the historic practice of considering only point sources of pollution if future water quality goals are to be reached. Future upgrading of municipal treatment plants and industrial dischargers should be viewed in light of potential large capital e.xpenditures for treatment structures versus reduced expenditures for minimum-structural or source control of nonpoint sources of pollution. The study recommendation was that "abatement of nonpoint pollution from urban runoff should receive high priority in future water pollution programs". The Minnehaha Creek Watershed District's overall plan (1969) noted that: "Urban development rapidly increases the amount of storm run-off in an area because the hard-surfacing of streets and construction of buildings reduces the amount of water absorbed by the soil. In addition, urban areas are usually graded and drainage provided to prevent accumulation of surface water. Since ground water aquifers are normally recharged by seepage of surface water, increased urbanization may be expected to bring not only greater surface water run-off but a decrease in the natural recharge of ground water". This finding lead to the MCWD policy that each municipality prepare a drainage plan for surface water resulting from urban runolTand that "each community should identify swamps and marshes to be left in their natural state", thereby acting as settling ponds and filters and avoiding direct runolTinto Lake Minnetonka. The "Harza Study", a program for prescr\ing the quality' of Lake Minnetonka, (1971) determined that the limiting nutrient for algal growth in Lake Minnetonka was phosphorus and that the natural function of marshland and wetland was to retard surface water flow and remove nutrients, especially the phosphorus. And, stomi water, especially that portion which runs off from urban lands, is expected to become an ever more important source of phosphorus pollution. The Harza Study noted that presets ing wetlands will play an important part in the future handling of storm water. As the watershed continues to increase in population, the rate of flow following stomis will tend to increase. The existing urbanized areas were found to be approximately 25% imper\ious while new urbanization tended to be 35% impcr\ious. Ihis factor plus the general rate of urbanization was at that time having the effect of increasing the water resources of Lake Minnetonka by an equivalent of 4.25 inches per year. This accelerated flow rate was causing pressure for the construction of storm sewers or other structures to convey the stomi water through the low areas and to reduce the w ater level increase. But. the construction of storm sewers or paved channels allows stomi water to CMP 3A- 16 by-pass marshes, thereby curtailing the benefit to be derived from them. On the other hand, by anticipating problems of localized flooding, development can be restrained in those areas, storm sewers can be avoided and storm water can be allowed to meander naturally through the natural filtration system of the marshes. Therefore, the Harza Study recommended that "the present policy of preserving lakes and marshes from filling be continued. It is further recommended that the future construction of storm sewers be minimized to those required to alleviate local problems. Storm runoff from the watershed should be encouraged to flow over marshes, not through them in conduits or around them. An attempt should be made to locate those areas adjacent to marshes which may be flooded intermittently because of increased runoff caused by future developments. These areas should be reserv ed from further development just as tho’igh they were a portion of the adjacent marsh". The Metropolitan Council's Storm Water Impact Investigation (1973) included several pertinent conclusions, as follows; 1. The total quantity of storm water runoff will increase if present urban development practices are continued. 2. The impact of converting an area of undeveloped land to dense residential use w ill increase the pollution load from that area by more than ten (10) times. 3. The storm water from dense residential areas averagesfourteen limes greater phosphorus concentrations than the lakes, based on the results of this study, other similar studies in Minnesota, and that found in literature. These concentrations are over nine times greater than the concentrations associated with nuisance algae blooms. 4. Storm water runoff accounts for almost all of the nitrogen and phosphorus added to the lakes and streams. This conclusion is based on average flows and quality of the effluents from sewage treatment plants compared to the flow s and quality of the storm water runoff. Based on this data and the previous published studies, the Storm Water Study included the following recommendations; I.The objectives of storm drainage design should be revised from rapid disposal to concepts w hich w ill decrease the impact of storm water by reducing peak flows and improving quality. CMP3A- 17 I I I I I I I I * 1-^ M H I* N H N 2. The design criteria should include concepts such as on-site disposal, retention ponds, retention of recharge areas and marshes, grass waterways, and other new methods of management of storm water which may decrease capital requirement for new development. The following storm water policies and guidelines were then recommended for consideration and adoption by the Metropolitan Council. These guidelines apply applied to the development of municipal and private drainage plans and storm water drainage systems including additions to existing facilities, and particularly apply applied to Orono in its endeavor to protect and preserve Lake Minnetonka; a. b. c. d. e. f. g h. The systems shall be compatible with metropolitan and local flood control plans. Storm water drainage shall be discharged to marshlands, swamps, retention basins or other treatment facilities prior to entering the public waters Diversion of storm water to marshlands or swamps shall be encouraged for existing or planned surface drainage wherever marshes and swamps occur naturally and are feasible as receiving bodies. Marshlands and swamps receiving storm waters shall include provisions for water level control. Temporary storage areas or retention basins scattered throughout developed areas shall be encouraged where feasible to reduce peak flows, erosion damage, and possibly reduce the total cost to the community. Wide, shallow, grass waterways, where feasible, shall be used as overflow channels from the retention basins to form an above-ground drainage network. This waterway concept should be coordinated with the greenways and open-space plans of the municipalities. Natural vegetation shall be used to reduce erosion in the waterways and act as a buffer between developed land and the retention basins. The practice of storing all stonn water from natural units on that unit shall be encouraged. Many residential lots may be amenable to this concept and thus, ideally, whole subdivisions may be handled by this method. M H I CMP3A- 18 1.If marshland swamp disposal is not practical, some means to reduce the level of settleable and suspended solids shall be constructed. j. The drainage system components should be designed to maximize upstream storage. k.Facilities for temporary storage or for treatment of surface runoff shall be designed for the discharge from a 100-year storm. Finally*, Orono ’s 1974 Surface Water Management Plan is was a detailed quantitative analysis of Orono's entire surface water drainage system. All wetlands and marshes were individually reviewed as far as watershed, urbanization, runoft characteristics, nutrient assimilative capacity and ponding capacity. Pollution loads to the marshes and ponds were determined based on phosphorus as the limiting nutrient. These loads took into consideration tributary acreage and potential development on the tributary lands. The maximum phosphorus loading comes from high density residential development and is 3.46 Ibs/acre/year. The assimilative capacity of the marshes was determined using two rates. Permanent standing water has an assimilative capacity of 4 Ibs/acre/year. Permanent standing water was defined as areas of the marshes having cattails and other emergent vegetation. The drver areas of the marsh, which have water in them only intermittently, absorb a greater amount of phosphorus and have an assimilative rate of 20 Ibs/acre/year. The study data was then compiled into one table listing all identified marshlands in the Citv (as shown on Map hlo. 4 and as legally identified in Orono s Flood Plain Management Ordinance No. 213) for purposes of determining minimum required marsh areas necessaiy to properly detain the surface water runoff, thereby avoiding Hooding and affecting nutrient assimilation. The data included in this table is outlined as follows: 1. Names of watersheds and code names for sub-watersheds. 2.Acreage drained to the individual marshes, with totals for the drainage areas where necessary . 3.The acreage of permanent water in the specified marshes and totals when necessary. 4.The acreage of intermittently flooded wetland and totals when necessary'.

The maximum residential density pollution potential for each specific drainage area with totals when necessary. The percentage of the marsh needed to assimilate the projected pollution in its drainage area. The acreage, if any, with the potential for development of duck ponds, within a marsh (located in permanent standing water and computed from the water quality data). The acre feet of storage available within the marsh. The acre feet of storage required to prevent the flood level from rising more than 1/2 foot. The percentage of each marsh needed to control flooding from a 24-hour, 100-year storm. The statistical result of this study was the realization that a natural storm water drainage and filtration system was economically practical for Orono. but that excessive urbanization would outstrip the natural capacity of most of the wetlands leading to flooding potential and to increasing levels of nutrient pollution in Lake Minnetonka. Three of the twelve study recommendations are most significant in terms of the effect on this the 1980 CMP: 1. 2. 3. Every available means should be utilized to preserve the natural w'ater storage and treatment system, which is one of Orono’s best assets. The City of Orono should protect land adjacent to marshes which require more than their total existing areas to control storm water runoff and preserve the water quality. The City of Orono should acquire supplementary land which is needed to preser\ e the integrity of the natural system of pollution treatment and runoff control. Orono took these recommendations to heart in its planninu durinu the mid-1970's, via adoption of more stringent develoment standards that allowed for the preservation of wetlands and required large minimum lot sizes to avoid the detrimental effects of urbanization CMP 3A - 20 I Orono 2000 Comprehensive Stormwater Management Plan The 1982 Metropolitan Surface Water Mana2ement Act ("Chapter SOQ") compelled regional and local watershed management planning. includin£ preparation of a watershed management plan bv the MCWD. Development of the MCWD plan was commenced in 1983 and completed in 1993. The MCWD plan establishes 7 general goals for surface water management: 1) reduce the severity of flooding: 21 improve water quality: 31 control sediment transport and deposition: 41 preserve flood storage capacity: 51 minimize dredging impacts on surface water quality: 61 maintain watercourse integrity: and 71 preserve the quality and appearance of shoreland areas. The MCWD plan and the Metropolitan Surface Water Management Act requires local cities, including Orono. to take certain actions to carry out the District’s plan: al prepare a local water management plan (or amend an existing planl in conformity with the Watershed District plan: bl establish a capital improvement program: and cl adopt local ordinances for implementation of the plan. The City of Orono concurrently with adoption of this update of the Community Management Plan, will adopt and implement the Citv of Orono Comprehensive Stormwater Management Plan (SWMPl completed bv Bonestroo and Associates. The general objectives of this Plan are: 1- Preserve Orono’s wetlands, streams and lakes, esneciallv Lake Minnetonka: 2. Reduce to the greatest practical extent the public capital expenditures necessary to upgrade the stomiwater system in order to meet water quantity and quality standards Improve stormwater quality in all protected waterbodies bv maximizing the amount of areas available for treatment: Minimize existing flooding, erosion and sedimentation problems generated b\ surface Hows.

The objectives of the Orono Stormwater Management Plan conform with the goals of the MCWD plan, and the Orono Plan conforms to all Regional. State and Federal requirements for local plans. The Orono Plan contains the following goals and policies: (INSERT GOALS AND POLICIES FROM SWMP Pages 10-14) SHORELAND MANAGEMENT fDraft 1-2 page summary of Orono*s philosophy on shoreland management and referenec the existing ordinances and history of regulation) (Insert Shoreland Overlay District Map here) TREE PRESERVATION (Draft brief 1-2 paragraph discussion of philosophy on tree preservation.

Orono will promote the formulation and active use of environmental protection policies by other Lake Minnetonka area municipalities and responsible government agencies. Even though Orono plays a key role in the protection of Lake Minnetonka, permanent preservation of the quality of Lake Minnetonka is impossible without coordinated policies and without active implementation of proven protective measures. Environmental enforcement may be difficult in the face of development pressures, but without commitment and sacrifice, a nibbling effect will surely place the goal beyond reach and beyond recoveiy. Environmental protection policies will be utilized in the formation of all other goals and policies in this CMP. Orono's commitment to environ ­ mental quality is carried throughout each element in this comprehensive plan, coloring the goals, policies and implementation practices in every facet of municipal responsibility. Development densit>' will be limited to a level which will not overload the natural surface water drainage and filtration system. Urbanization increases the speed and quantity of surface runoff while decreasing the water quality. Developed land use densities will be determined by comparison between known levels of volume and pollution generation and known marshland capacity for ponding and nutrient assimilation. Surface w ater runoff w ill be directed through the natural drainage system. Direct runoff into the lake will be avoided and will be prohibited whenever possible. The longer the routing of storm water between source and the lake and the longer the duration of ponding in a wetland, the more nutrients are assimilated and the more silt is settled. The transfer of storm water runoff from one local watershed to another or recycling water through the same marsh, will be pursued and encouraged as a practical method for increasing the duration of water retention before runoff enters the Lake. The result of extended retention w ill be improved lake water quality. Natural drainageways will be favored over artificial storm sew ers. Storm sewers speed runoff and provide no natural filtration or nutrient assimilation. Storm sewers will only be utilized in local flood prone areas or where there is soil erosion insolvable by natural means. Whenever possible, storm sewer outlets will be directed into marshland or natural drainageways and not directly into the lake. Storm sewer systems will not be considered for new developments or where satisfactory natural drainage systems already exist. I’ H CMP 3A - 24 6. 7. 8. 9. 10. The wetlands and marshlands of the city will be protected and preserved as wildlife habitats, as unique open spaces, and as the only economically practical method of flood protection and storm water runoff filtration. The Harza Study, the 208 Water guality Management Study, and Orono's Surface Water Management Plan all recommend this approach to permanent water quality management for Lake Minnetonka. In addition, the Orono Plan goes on to identify individual wetlands and marshlands that require protection as part of the City's storm water management program. It is the policy of this plan to effectuate the policies and recommendations of the 1974 Orono Surface Water Management Plan. Protection of the city 's marshland, wetlands and drainageways shall include protection of adjoining lands and prevention of drainage, filling dredging or wetland's vegetation removal. Ordinances will establish setbacks for all land alteration or construction. Wherever possible, the City will acquire open space and flowage easements for conservation of these lands. Protection of lake resources w ill allow reasonable access, use and enjoyment while preventing overcrow ding and excessive encroachment. In conformance with Mn. DNR Shoreline Management regulations for Recreational Development lakes, the City will prohibit overly dense development within 1,000 feet of Lake Minnetonka. Lake use regulations will be promoted to limit excessive boat density and overuse of sensitive bays. Land use regulations will be developed to provide reasonable control over building density, land alteration and lakeshore encroachment. Lake shorelines will be protected from alteration. Natural vegetation in shoreland areas will be preserv'ed insofar as practical and reasonable in order to retard surface runoff and soil erosion, and to utilize excess nutrients. Clearcutting will be prohibited. In areas of soil or wave action erosion, natural stone rip rap shoreline protection will be encouraged. Lake bed alterations will be discouraged because of adverse short-term and long-term effects on water quality. Dredging of lake beds releases large amounts of otherwise trapped nutrients and silt which adversely affects water quality for long periods of time. Dredging of new channels or inlets will not be approved to provide riparian access where none existed naturally. Dredging will be permitted in limited circumstances only where absolutely necessary to maintain existing natural riparian access permanently lost by something beyond the control of the landowner. Periodic low water conditions or the owner's desire for deeper draft watercraft are not sufficient reasons for disrupting sensitive lake beds. CMP 3A - 25 I I 1 1 :i » I ••I •M I I I I r r r r 11. Development or alteration of floodplains will be restricted. Most of the City's identified floodplains are located along the shoreline or within designated marshlands and will be protected by other provisions applicable to those areas. In addition, where floodplains do exist on otherwise dry buildable land, construction, filling or alteration will be strictly controlled so as to avoid flow restrictions, to avoid flood level increases on other properties, and to avoid costly flood damage or pollution dangers. 12. Natural resource investigation will be required as part of all development proposals. 1 his will include topographical intormation, soil analysis, drainage plans, vegetation plans, erosion control measures and similar site data related to each project, whether public or private. The extent of each such review will be determined by probable environmental impact. Greater detail will be required of larger projects than of smaller ones. As proximity to Lake Minnetonka or a major wetland increases, so will the care and concern increase in direct proportion. 13. On-site water retention facilities will be required as part of all residen* tial, commercial or industrial development projects whenever necessary' to maintain or improve the existing storm water runoff patterns. Whenever a development’s location, size, scope or hardcover would tend to increase the quantity' of runoff, increase the speed of runoff, or decrease the quality of runoff, that development will be required to provide on-site retention facilities sufficient to maintain the existing situation or to improve the resulting runoff by reducing quantity, reducing speed and/or improving quality. No development will be pemiitted to adversely impact it's neighbors, or the City, by changing drainage patterns or by otherwise adversely affecting storm water drainage. National Urban Runoff Program (Nl IRP) standards will be applied to the desiun of new stormw ater ponds. (This amendment was required by Met Council per CMP Amendment No. 5 adopted via Resolution No. 3343 on 10-25-93) 14. Land use and development will not be permitted at the expense of environmental protection. No land will be permitted to be subdivided or built upon which is held unsuitable by the City for the proposed use because of flood hazard, inadequate drainage, soil formations with severe limitations for development, severe erosion potential, unfavorable topography, inadequate w ater supply or sewage disposal capabilities, or any other feature likely to be harmful to the health, safety, or welfare of the future residents of the proposed subdivision or of the community. No land use will be al lowed to adversely affect the neighborhood ’s air or water resources nor w ill any use be permitted to emit noise, dust, electrical or radiation pollution. C.MP 3A - 26 I 15.Erosion control plans and programs will be required in all land alteration projects. Each contractor will be required to minimize the probability of soil erosion on site and/or siltation damage downstream. The smallest amount of bare ground shall be e.xposed for as short a time as possible. Temporary ground cover will be required until permanent cover is provided. Sediment traps will be required on slopes and between construction sites and public roadways. Fill must be compacted and stabilized for permanence. Erosion control Best Management Practices shall be annlied to all land alteration projects. The MPCA’s Urban Best Manatzement Practices entitled “Water Quality in Urban Areas” shall be annlied to the review of proposed developments to reduce non-point source pollutant loadings in storm water runoff. To implement this policy, the Citv wioll incorporate these standards and requirements in its its stormwater manatzement plan and land use controls. (This amendment was required by Met Council per CMP Amendment No. 5 adopted via Resolution No. 3343 on 10-25-93) I I 1 1 1 1 URBAN AREA POLICIES FOR NATURAL RESOURCE MANAGEMENT 1. 2. 3. Land use standards will limit the impact of urban encroachment on Lake Minnetonka. Minimum lot widths will space out docks and structural encroachments while increasing areas of natural vegetation. Lake use regulations will limit the number of boats per property and the amount of public waters available for private docking and boat storage. Retention of natural vegetation will limit the impact of urbanization as visible from the lake. Building heights will be limited to less than the typical tree height. Minimum green belts will be provided with prohibitions against clearcutting or e.xccssive thinning of vegetation. Natural vegetation will be preserved on slopes. Retaining walls will be discouraged except when absolutely necessaiy to pre\ent erosion, in which case they will be screened with natural vegetation Direct runoff into the lake will be minimized. Standards will be established and maintained to limit the amount of impervious hardcover in proportion toclosene.ssofthe shoreline. Maximum hardcover will be limited to 30% of each parcel within 1,000 feet of the shoreline pursuant to Mn. DNR recommended shoreline practices. CMP 3A - 27 I I 4.All existing urban wetlands will be maintained and protected for surface water retention and filtration. The existing urban runoff exceeds the capacity of the urban marshes to assimilate all nutrients, therefore additional pollution hazards would be created if any wetlands would be lost. Additional steps to improve nutrient assimilation include on-site retention on all new developments and storm water recycling through the existing marshes. 5.City maintenance practices will be designed to improve storm water quality. Salt use for winter street treatment will be minimized. Snow- removal practices will locate temporary storage sites where they will not overload the natural drainage system or where foreign matter, especially salt, will not directly enter a marsh or lake. Spring cleanup will promptly remove road sands and salts before environmental damage occurs. 6.A signiflcant amount of natural woodlands and open space will be retained on each property. Retention of the natural environment requires careful siting and preservation of trees and open space on each urban property. 7.All developments will be designed to assure protection of light, air, and solar access for neighboring properties. Requirements for minimum lot size, amounts of open space, minimum yard setbacks, and maximum building heights will be designed to assure protection of these values for all urban residents. RURAL AREA POLICIES FOR NATURAL RESOURCE MANAGEMENT 1.Land use standards will limit the pollution loading of rural marshes and drainageways. Rural densities will be low enough to ensure permanent reliance upon satisfactory on-site sewer and water systems where municipal sewer is not feasible and to ensure that rates of phosphorus and nitrogen generation will not adversely affect the water quality in the natural drainage system. 2.Rural land use densities w ill allow maximum retention of private woods and open space. Low rural densities will accommodate homesites without affecting the traditional vistas of open fields and woods. The retention of these woodlands and marshlands will then assure permanent habitat for our abundant wildlife. CMP 3A - 28 3. 4. Rural wetlands and marshland will be maintained and protected for surface water retention and filtration. As total watershed population increases, even at our relatively low rural densities, the volume of runoff increases as does the nutrient input. Upland marshes and wetlands will be required for flood control water retention and for maximum nutrient assimilative capacity. The City will promote farming practices designed to conserve the soil and ground water. Where farming occurs in the rural areas, the use of innovative tilling methods, land banking, crop rotation and wind breaks are encouraged to protect the native soil from erosion and deterioration. Animal sanitation methods will be enforced to assure minimal pollution of drainageways or ground waters. I I 1 1 1 1 1 1 CMP 3A - 29 I I f ii 1. 2. 3. t * 4. 5. 6.

Housing is basic to the quality of life of all people yet many persons, particularly those of low and moderate income level and those on fi.xed incomes, are living in substandard housing or are denied adequate choice in housing type or lifestyle. The rapid increase in prices and the inadequate supply of newly built affordable and lifecvcle housing have meant that middle as well as low income persons are increasingly unable to afford housing that meets their needs and desires. At the same time, much of the area’s housing is aging, and there is an increasing need for neighborhood preservation and housing rehabilitation. The Metropolitan Land Planning Act requires that local comprehensive plans include "official controls and land use planning to promote the availability of land for the development of low and moderate income housine" (Minn. Stat. Sec. 473.859. Subd. 2). To flirther address housing needs, the Minnesota Legislature in 1995 enacted th»" Metropolitan Livable Communities Act, establishing a fund for communities to invest in local economic revitalization and affordable housing initiatives. The Act provided for funding in three specific areas: cleaning up polluted land: revitalizing communities and promotimi efficient development: andproviding housing affordable to people with moderate incomes. The Metropolitan Council has identified (and the Citv Council has acknowledged) three major housing problems that e.xist in the Metropolitan Area that affect Orono : 1.There is an inadequate supply of lower cost housing in good condition and large numbers of people arc inadequately housed. Much of Orono's housing stock consists of winterized summer cottages or farmhouses dating to the early 1900's, although these are steadily being converted to. or replaced with, more substantial housing of significantly higher valuation. l.ow and moderate income housing is largely concentrated within the two center core cities. W'hile this is true for the Metropolitan Area as a whole, it is also true for Orono and other lake area communities on a smaller scale that have where substantial neighborhoods of older homes built 50-100 years ago are in need of repair or upgrading. CMP 3C - 1 V 3. Middle income persons are increasingly unable to afford housing suitable to their needs and wishes. The gap between the price of housing and incomes has been steadily widening, with ever greater numbers of people priced out of the housing market. The result is that even the middle income family is faced increasingly with substantial difficulties in finding affordable housing which is suitable to its needs. This is of particular concern in Orono. whprp fully 1/3 of the housing stock is valuable lakeshore property, and the developing off-lake housing in rural Orono has been skvrocketinp in value due to a keen dema nd for the low-densitv lifestyle and amenities. This Housing Plan is an indication of the ongoing policies and concerns of Orono residents toward solving our own housing problems. This Ph n is a refinement and restatement of the planning direction established in the 1974 Orono Village Comprehensive Guide Plan and the 1980 Orono Community Management PInn and is prepared and presented for the following purposes: 1. The Housing Improvement Plan is intended to provide a review of Orono's existing housing stock. As an outlying municipality on the d eveloping fringe of the Metro area, especially one with miles of desirable lakeshore, it is easy to forget or to overlook the true housing situation in Orono. By providing a brief review of e.xisting housing statistics, one quickly realizes that Orono is not a typical "new" suburb of middle income monotony. 2. The Housing fmprorcmmt Plan is intended to be a management tool for City officials. City staff and other parties interested in improving the condition of Orono's available housing supply. As such, the Housing Plan includes goals and policies aimed at guiding housing improvement consistent w ith our Land Use Plan, local housing needs, and the Metropolitan Council s policies for low and moderate income housing. The Housing impros eiiieiit Plan is the housing element of tmr Orono's Community Management Plan, designed to advise the Metropolitan Council of our hou.«ing needs and intentions. The Metropolitan Council is the responsible regional agency charged with reviewing subsidized housing plans and ^.i^grams foi the jica the housing element of local land use plans asirequired bv the Metropol itan Land Plannino Act. This plan is designed to advise the Metropolitan Council of our existing housing situation, our analysis of local and Lake Minnetonka area housing needs and our proposed programs for meeting those needs. 3. CMP3C - 2 BASIC HOUSING CONCEPTS AND PRINCIPLES I The Housing linpr ovcmciit Plan is an integral part of Orono's Community Management Plan. Although the statistics and detailed policies apply specifically to this one element of community planning, the overall goals and objectives have been derived from Joint and concurrent consideration of all community planning elements. Therefore, the policy decisions relating to Orono's housing improvement programs complement and balance regional plans with local concerns for historic development patterns, environmental protection, public health, fiscal responsibility and general land use. Orono's urban and rural areas provide distinctly different lifestyles, amenities and services which jointly benefit the community as a whole. Each area has separate planning priorities and separate environmental considerations. Urban areas and urban services will not be permitted to encroach on or destroy the rural area of the cit>'. Historic development patterns established 100 years ago are responsible for the dual personality that characterizes Orono. The lure of the Lake drew summer residents and resorters who established the crossroads of Navarre, which continues to this day as the commercial center of Orono. Likewise, away from the Lake, Orono has developed slowly as a community of •'ural residential w oodlands and open space. The lifestyles are different, the needs and desires of the citizens are different and the requirements for public services are different from the urban area of Orono. Orono's urban areas have historically provided ample opportunity for a vast spectrum w ide ranee of housing opportunities and all of the neighborhood ser\ ices necessar>* to support the residents of the City, urban and rural alike. These areas contain most slightly over half of Orono's existing housing stock and most of the existing substandard housing stock. Orono's rural areas in the past have provided the opportunity for low density housing at affordable prices, orchards, greenhouses, hobby farms and recreation areas not possible in either urban areas or in commercial agricultural areas. This low density of land use is has been and will continue to be particularly valuable as a protection for the marshlands, woodlands and other natural resources that dot the area. Here, where housing is often as old as in the urban areas is scattered among housing developed over the last 20-30 years, btrt the overall density is low and no urban services are available. CMP 3C - 4 As the rural area has developed over the last two decades, particularly in north central Orono. land values have skyrocketed, driven bv market demand for the rural lifestyle provided bv low-densitv development. The resulting conversion of farmsteads into primarily higher value single family neighborhoods, has occured at a rate that iust keeps UP with demand. New rural lot developments are typically sold out within the first year. This ongoing demand has made it difficult to acquire land at prices that would allow For development of affordable housing without conversion to urban densities. Clearly, the needs for affordable and lifecycle housing will not be met in Orono's rural area. Orono has acknowledged the need for a wider range of housing alternatives, both within Orono and within the Lake Minnetonka area, and has taken steps to provide new locations for development of urban density housing where it will not be in conflict with the rural area. These areas will be rezoned to allow for appropriate urban housing densities and will become a part of Orono's urban serv’ice area. Orono's land use plan calls for development in both the urban and the rural portions of the City. The urban area will see new residential development on the existing vacemt lots and undeveloped parcels similar to the forms of development projected for typical of the closer-in suburbs. Opportunities exist for substantial rehabilitation projects in the older urban neighborhoods and for scattered-site new construction of subsidized affordable and lifecvclc housing units. Overall urban density will remain relatively low because of the ecological considerations of proximity to Lake Minnetonka. New areas proposed for urban development located primarily outside of the defined Shoreland area will be developed at densities ranging from 1 to 4 or more units per acre, commensurate with the City's identified need for a wider ranue of housing alternatives to serve an expandinu ramie of housing needs. The rural area will sec continued residential development at a steady pace with most land divisions resultinu in the creation of 3-8 lots being of the t\w to four lot variety. Strict subdivision review will ensure adequate retention of privately owned and maintained open space, wetland conservation, and on-site sewage treatment system site evaluation. Scattered rural rehabilitations will be necessary on the older homes and cottages in certain existing rural housing clusters. The typical rural lot will continue to provide modera te income alternative a hiuhlv desirable lifestyles as the low investment in public scr\ ices continues to make the land competitive with more fully developed suburban properties. I I 1 I I I I I I C.MP 3C - 5 I I I Orono's land use plans and programs allow new urban and rural developments to provide comparable cost housing opportunities. Orono has never had regulations requiring arbitrary minimum square footage in homes. Orono has never required such cost increasers as garages, paved driveways or mandatory landscaping. Any structure which conforms to State Building Code safety requirements can be built on any residential lot in the City. In addition, Orono has had long experience with rural residential development including a full six years a quarter century of requiring at least 2.0 acres of dry buildable land for each rural dwelling. From this experience, Orono has found that housing built on rural lots of 2 acres per dwelling can be and is often comparably priced with housing built on ty pical 10.000 square foot 1/4 to 1/3 acre suburban lots in neighboring developing cities. The difference is one of lifestyle and necessary ’ public improvement investment. The typical suburban lot requires massive amounts of investment for improvements necessary to allow urban density, including sanitary sewers, municipal water, storm sewers, p aved public streets, street lights, large-scale earth moving and landscaping or erosion control measures. Indirect costs include park development fees, and increasing taxation to pay for schools, police, fire and general governmental expansion. Development time often exceeds a year or two from concept to reality. All these costs, plus large, long-term carry’ing charges, are built into the cost of each urban home. On the other hand, rural development as practiced in Orono is relatively quick and inexpensive. Small rural subdivisions have been completed within 90 days. Each rural lot is subject to extensive site and soil evaluation to ensure adequate, permanent on-site septic system operation. But, the installation of on-site septic systems and individual wells cost s co ns iderably less per un it th an are comparably priced with municipal sewer or and water systems. There is n o extensive The extent of land alteration and no storm sew er n ecessary construction is minimized . A11 access is via the existing street system or by new roads privately owned and maintained by the landowner. Road construction is less expensive, because of the limited-use rural sections need not be built to urban design standards. Municipal tax levels remain the same because the development density can be accommodated within the means of the existing public services and facilities. Thus Orono's two acre lots provide a vastly different lifestyle for the same market price as other cities' 10.000 square foot 1/4-1/3 acre urban neighborhoods. t * CMP 3C - 6 B POPULATION FORECASTS HOUSEHOLD FORECASTS YEAR 1970 1980*1990 2000 Saturation 1970 1980*1990 2000 Saturation i .-i Urban Area 4160 4250 5120 5900 7200 1400 1450 1740 2000 2400 Rural Area Kill 3040 3220 3640 3800 746 980 1040 1180 1267 % Total City 61S1 7290 8340 9540 11000 2146 2430 2780 3180 3667 1 I I I r 4 I I (NEW TABLE) ORONO POPULATION PROJECTIONS (November 1999) Population Forecasts Year Urban Area (1/2 & 1 ac.)

Orono's land use plan accommodates all expected population growth in a wide variety of housing opportunities. The forecast population increase of 2,240 appro.ximatelv 1500 persons in the ne.xt twenty years translates into a housing demand of approximately ?50 900 new dwelling units. This average of-3? ^ new dwellings per year is consistent with or slitihtlv above Orono's rate of actual building permit issuance during the T9764 past three decades . From past experience and based on the Land Use Plan, approximately 40% half of these new units are expected to develop in the urban area and approximately 6 0% half in the rural area. The Metropolitan Council's Regional Blueprint and the Minnesota Livable Communities Act emphasizes the advantages of free choice a wide range of housing alternatives and in housing locations such as that afforded by Orono's differing urban and rural neighborhoods. The location of housing alternatives is directly related to the opportunities and services enjoyed by residents of the Metropolitan Area. Location intluences not only access to employment, but also the availability of neighborhood parks and recreational programs, libraries, health care facilities, day care centers, and access to major retail centers, highways, and public transit. Thc-Metropolitan Council therefore rccommend s-that-people freedom of choice in the location of tfaefr housing. CMP 3C - 8 I The Metrop oli tan ■ Coun cil - has designated Oro no as a "third prio rity” co mmunity insofa r as urban ho using po licy is co ncerned. Co mmunities with Imd n-ithin the Metro po litan Urban Service Area (MUSA) are expected to plan adeqiate land fo r pro jected ho using gro vMh and to pro vide an appropr iate share o f ho using fo r perso ns o f a «mge o f inco me levels. The regional ho using po licy calls fo r subsidized housing to be located near activity centers or as part of ' new towns ' or large scale Planned Unit Devrlop ment offering adequate levels o f services and facilities, and near high amenity areas. As a third prio rity co mmunit}*-; Oron o dees no t co ntain such large scale acti\nty centers and therefo re is generally lew in prio rity* fo r the alloc ation of such housing. Plans o f third»prierity co mmunities’are expected to be more long-term and less detailed than plans o f inner»ring suburbs, with unit alloc atio ns being fairly limited numbers and in so mewhat more distant future. The need for rehabilitation and redevelop ment is generally no t high in third-apriority communities, but it is an impor tant need in Oro no because o f the age o f so -much of our urban ho using stock. Successful development of a wide ranee of housing alternatives is directly related to the ability to obtain the necessary infrastructure and public services. In today’s market, affordable housing and many forms of lifecvcle housinu are only feasible at urban densities, which require urban infrastructure such as municipal sewer and water, and the wide range of urban services not available in the 80% of I Orono that is planned for low-densitv rural residential development. New housing alternatives in Orono are planned primarily to occur within the existing urban area as well as in specified urban area expansions that are detailed in the Land Use Plan. These housing options will include a range of housing styles and types at densities of 1 to 4 units per acre. Where feasible, affordable housing units will be incorporated within multi-unit new^ housing development. The Metro po litan Cou ncil recognizes that rural commun ities require different housin g programs than do urban comm unities. Metropoli tan Co uncil po licy do es not enerrurage urban'-scalc residential dcvelo pment"hr the Rural Service-Area, nor does C-Ouncil policy suppoi t the de vx lopment of subsidized housing in the rural areas? Rural needs for subsidized housing are to be met within the Freestanding Growth Centers such as Maple Plain, or within the existing Urban Service Area, including Orono s urban neighborhoods and other urbanized lalce area cities such as \A^ayzata,‘ Lo ng Lake and Mound , where urban services and amenities are available.

This is true of both the urban and the rural areas of the City. The number of multi-familv structures has remained small with most of these units located in the Navarre Area. The small amount of existing multi-family development is traceable to a lack of undeveloped urban land, to a lack of available transportation or significant shopping facilities, and to the availability of numerous apartments in nearby Mound, Spring Park, Wayzata and Excelsior.

The high percentage of seasonal/vacant units mav be a reflects reflection of the lake-cottage heritage. While many old cottages have been converted to rental or year-round dwellings in the past, there remain a significant number of cottages on the islands which will likely not be converted in the future. Age of Existing Housing Stock Table indicates the ranee in ages of Orono's existing housing stock bv defining the decade of construction. Approximately 30% of the housing stock is more than 50 years old, which raises concern about its continued functionality if attention is not paid to significant upkeep activities. The percentage of housing units constructed prior to 1950 is significantly higher in Qrono than that for the Lake Minnetonka area as a whole. These units generally occur in the rural area or in clusters that developed historically around Lake Minnetonka, such as the Crystal Bay. Stubbs Bay. CMP3C- 11 I I I 1 \ I J' J \ I I J I I I Minnetonka Bluffs and Navarre neighborhoods. Over 40% of the housing stock is in the 20-50 year aee range, where style updatin2 and normal maintenance such as roofs, heating systems, etc, require ongoing investment. The numbers in Table do not necessarily reflect the extensive remodeling and upgrading that many Orono residences, especially lakeshore homes, have undergone in the last two decades.

To acco mplish-this task, recogniz ed gutdelines were used to rate each unit surv eyed by exte rior structural co nditio n, with the-ho using units being rated as Goo d, Fair, Deterio rated or Dilapidated. The results of this the 1978 windshield survey indicates indicated that a very high proportion of the housing stock in the City is was in good condition by exterior appearance. Most of the deteriorated or dilapidated structures are were located in the older areas of Navarre or in some of the rural housing clusters as identified in the 1980 CSPP. Others are were isolated houses which hare had not been maintained or c ccupied in many years. It was also noted during the windshield survey that several of the deteriorated housing units arc were either in the process of or have had already undergone certain amounts of rehabilitation. A further review of housing in the City in 1997 suctzested that while the condition of housing in the rural areas and on the lakeshore had remained generally good, much of the older housing in the Navarre area appeared to be in need of major maintenance. Because Navarre provides a significant portion of Orono's 'affordable* housing stock (housing meeting established rent/valuation guidelines for low and moderate income groups), the poor apparent housing condition was deemed to be a critical concern. As a result, the Citv initiated the Navarre Housing Study in June 1997. including a field study, a mail survey, and research. The survey collected demographic and income information, as well as information regarding residents' plans for, and ability to complete, future rehabilitation. A summary of the study is included in the following table: CMP3C- 13 RENT RANGE OF RENTAL UNITS (1990) Monthly Rent it of Units % of Units <$:oo s 3.7% S200-299 5 2.3% S300-399 21 9.6 $400-499 34 15.6% S500-599 37 17.0% $600-749 45 20 6% S750-999 23 10.6 SIOOO or more IS .S 3 “» Total with Cash Rent 191 87.7 % No Cash Rent 27 12 3 "o Total 218 100.0 % Source: 1990 U.S. Census Low 3nd N'locicrjtc Income llousirui In 1 9 70. approximatd>H-7.6 perreent of Oronn’s total-housing stock was in the price rcinyc litt'orcIiiHlo lownnd nioJcrjtc incviiie pcrsviiis «is Jcfincid by the Nlctropolittin Cmincil and using federal gu idelines.

Suhsid'/cd Hou.sinu Units At the present time, the City of Orono does not eontairj any units of subsidized housing. I his is due in part to the lack of. or limited shopping and employment opportunities, public transportation, medical facilities and limited extent of other eommunity ser\ ices such as municipal seuer and water systems. C'MI’sC- 17 I I I I I I I I [ I I I I I I I I METROPOLITAN HOUSING SUBSIDY ALLOCATfON The Metropolita n Council ha s adopted a Subsidized Housing Alloca tion Pl;m to help achiev e the goa l of increasing locati onal choice For low an d moderat e income households throughout the a rea. To a ccomplish this, the Council has determined priority a reas to assis t in the distribution of all ocat ed units. Orono. due to its lev el of serv ’ices and fa cilities has been designated a third priority community and bas ed upon this, has been all ocated a modest am ount of subsidized units. On rebrua r>‘ 28,-F98 0 ,-the Metropolitan Council ad opted a new allocation procedure for subsidized housing units for the period 1980 -1983. The formula has changed whereby a dolla r am ount for different subsidized housing programs has been all oca ted to ea ch commonit}*. These all oca tions were made on the basis cf tou^ census population an d projected population growth. No adjus tment was ma de in considera tion of Orono's limited urban are a or limited urban sendee capabilit>‘. The following tabl e indica tes the dollar am ounts all ocat ed to Orono al ong w4th the preferred usage for those funds as determined by the Metropolita n Council, and as rev ised by Orono to reflect only our urban populat ion percentage: only 58% of Orono's popula tion and 59^ij of Orono's households ar e located within the Urban ooC rvic e Area. 1 lOUSCl lOLD-TYPE-ALLOCATION—(TABLE FROM P. CMP 5-10) Orono's local needs assessment program has identified a strong need forelderh’ assis tan ce senior housing and a broader ranee of housing choices, and a strong need for substantial housing rehabilitation. In many cases, this is the identical need which has been generated by the major development surge that occurred in Orono between 1946 and 1955. These post war years were when most of our population increase occurred as returning ser\ icemen purchased former seasonal lake cottages and turned them into year-round residences. They raised families and stayed in their home. These people are now retired and on fixed incomes, fhey are often widows or widowers without ready resources. This phenomenon also accounts for Orono's relatively low persons per household figure as used in tnc CSPP. These long term Orono residents are living in substandard conditions by todays standards. They need help or they will be forced from their homes w ith nowhere to go. Thus. Orono has identified one of our greatest needs as housing rehabilitation for elderly senior-citi/en homeowners and for alternative elderly senior housing accommodations in the immediate lake area. CMP3C- 18 I I I I In response to the Met Council benchmarks, the City Council in Junel996 adopted a Housinti Action Plan identifying rehabilitation of existing substandard housing as the City ’s top priority, citing limited commercial-industrial development or employment opportunities, and limited availability of public services, as barriers to providing opportunities for life-cvcle and affordable housing in Orono. The Livable Communities Act additionally established a minimum required level of annual local spending towards affordable and life-cvcle housing needs, known as the Affordable Life-cvcle Housing Oportunities Amount (ALHOA) based on the City ’s homestead net tax capacity excesses. Orono*s oast expenditures toward the ALHOA have been primarily from Community Development Block Grant funds earmarked for residential rehabilitation urants and loans. I [ I I Meeting Sub-Regional Housing Needs Requires a Sub-Regional Approach The Metropolitan Council's Regional Blueprint suggests that each metropolitan area community is expected to provide a range of housing options to meet the needs of residents at all stages in the lifecvcle. and where feasible, increase options for affordable housing. Once needs have been identified, th r . a plan for meeting those needs must be established and implemented. The Lake Minnetonka area is comprised of a number of individual cities, both larue and small, each of which have the capacity to provide housing for certain 'niches'of the population, but few of which have the capacity to provide for all cateuories of lifecvcle or affordable housimi. In order to identify the existing life-cvcle and diversified housing, and to identify opportunities for such housing from a sub­ regional perspective, the 16 Lake Minnetonka Area Cooperatinti Cities (l.MACC) in 1998 prepared a Sub-Retiional Housing Study. The LMACC Study identified a number of kev issues which set the stage for addressini: problems and identifvimi opportunities for development ot adequate housinu in the subretiion. The kev issues re. tte to two primar\ factors: the changing profile of the LMACC cities, includinti demouraphics, life-cvcle housinu. population turnover, and low/moderate income households: and the housing stock, includin g market trends, housimi conditions, housinti valiics. and housing options The Study proposes a series of 6 Housine Initiatives, iiidudmg: A Subregional Approach to addressimi housimz needs; Actions to create Sustainable Communities; Development of Diversified Housing Options: listahlishment of Sunnort Scr> iecs such as transit access, child care assistance, etc. 21 21 4j CMP 3C - 20 I Establishment of a Subregional Housing Redevelopment Authority fHRA^: and Protection of Existing Housing, Housing Needs Related to Highway 12 Bypass The Highway 12 Bypass expected to be completed ca. 2006 will result in the acquisition bv MnDOT in 2000-2001 of approximately 90 homes within the City of Long Lake and another in Orono. The Citv of Lone Lake does not have sufficient land area to accommodate relocation of these homes, many of which are in the $ 1 00.000-200.000 price ranee. Orono’s CMP now proposes to expand the MUSA in the area east of Willow Drive between the Burlington Northern Railroad and Watertown Road, and plans to re­ guide this area from 2-acre Rural SFR to Urban SFR at a density of 2-3 units per acre, similar to the adjoining development in Orono’s Hackberrv Hill neighborhood and to abuttinu residential development in Lone Lake. The primary purpose for this expansion is to provide land for in-kind relocation of Lone Lake home displaced bv the Highway 12 Bypass. Because market forces would potentially tend to result in development of this area with homes in the S250.000-500.000 ranee, the Cit>' of Orono will investigate and promote methods bv which the desired price range housing can be assured. I I I I I 1 CMP3C-21 HOUSING IMPROVEMENT GOALS AND POLICIES Orono's Housing Improvement Plan is based upon the following Goals and Policies which are designed to be consistent with our regional housing responsibilities and with the Goals, Policies and Plans of the other elements of the Community Management Plan. HOUSING IMPROVEMENT GOALS 1. 3. 4. 5. To improve the housing conditions of persons residing in substandard housing. 2. To provide safe, healthful, and blight-free residences and neighborhoods. To provide opportunities for a mix of housing types, locations, and cost ranges which will meet the needs and provide adequate housing for all age and family groups. To provide housing types and residential densities consistent with environmental and land use plans and with the availability of public services and facilities. To provide immediately beneficial housing programs for the greatest number of needy Orono residents. URBAN HOUS 1 NG PQLl C 1 ES 1. 2. The residential areas of urban Orono are primarily suitable for single family homes. Because of historic development patterns, most of Orono's urbanized neighborhoods are located along the Lake Minnetonka shoreline, or within 1,000 feet cf the shoreline. These lands are environmentally sensitive to overuse or over development such as typically occurs with large scale developments. Low density residential land use is compatible with Orono's environmental policies of limited hardcover and ma.ximum retention of natural open space and vegetation. Alternative housing types will be provided by planned residential developments. A limited amount of land is available within the Urban Service Area for planned developments of attached townhomes. garden tj'pe apartments or mi.xed residential and limited commercial land uses. These housing clusters or multiple family developments will be acceptable only where full urban services are available and only where the proposed density I CMP 3C - 22 is compatible with the neighborhood and with local environmental constraints. Multiple family developments generally will not be considered appropriate for lands within 1,000 feet of Lake Minnetonka nor for areas such as Navarre that have limited transportation access to outside employment or shopping facilities. Increased density housing alternatives will be primarily developed along Orono’s Highway 12 corridor in specifically identified areas that are or will be served by urban services. I I I 3. 4. 5. 6. Urban density residential development must occur within the existing deflned Urban Serv ice Area. Orono's Community Management Plan is not a staged growth plan. The Urban Serv ice Area as defined in this Plan will not be expanded into the defined rural area and urban services and facilities will not be extended into the rural area for purposes of fostering or allowing increased development in those areas. Urban density residential development will utilize existing or planned public services and facilities. New residential development will be allowed to infill existing vacant properties within the Urban Service Area consistent with environmental limitations and with the existing or planned capacities of water, sewer, drainage, transportation and recreational facilities. New development will not b-* permitted to overburden these services at the expense of the existing users. New urban development will not be permitted if it requires additional unplanned local or regional facilities capacity. The city will promote scattered site development as opposed to large scale tract development within the existing developed urban area. Scattered site development has less impact on the existing neighborhoods or on the existing jj’iblic facilities capacities than does a concentration of development at one location. In addition, most of Orono's existing urban neighborhoods are a homogenous mix of newer and older homes intermingled with an occasional vacant lot ora larger, divisible lot. There is no single neighborhood which is in need of complete renewal or rehabilitation. Therefore, there is no need for nor any economical way of assembling a large tract of property for single-project development. The City will promote rchabilitutioii of existing older or substandard homes. Whereas there is no identifiable block of deteriorated housing in the City, there are a substantial number of older homes or converted cottages that are in need of repair, energy conservation measures, or major rehabilitation. In man; cases, these-homes arc occupied by low income or fixed income persons who cannot undertake the needed work within their means. The Citv’ will promote private and subsidized public rehabilitation efforts to improve the existing housing stock, to improve and maintain the neighborhoods, and most importantly to improve the living conditions of the affected citizens. CMP 3C - 23 I I I p f • I » 7.The City will promote development or rehabilitation that is compatible with the existing neighborhood. The City will encourage all homeowners and developers to be conscious of the neighborhood, the site and the environment in the design and improvement of residential properties. The City will encourage, and in many cases, require the retention of woods and vegetation, open spaces, light, air and scenic views. No new development will be permitted to conflict with or to adversely affect the established neighborhood character. 8.The City will promote subsidized rehabilitation that benefits the existing, often long term, Orono resident. Our citizens are Orono's greatest asset. As they grow older, we should not turn them out of their homes, but rather we should help them provide safe and comfortable living conditions in their existing neighborhood. RURAL HOUSING POLICIES 1.Housing in rural Orono will be limited to single family homes at established rural densities. Orono's Land Use Plan iw will result in an ultimate rural density of one dwelling per seven acres on minimum lot sizes of 2-to 5 dry-buildable acres each, and one dwellimi per four acres where the zonina requires a minimum 2-acre lot size. This density is consistent with the City's environmental protection commitment and is consistent with the overall Goal of preserving the historic rural character of the area. Because of this preferred use, and because there is no provision for any municipal sewer, water or other urban services, multi-family development or any densely clustered residential development will not be appropriate for rural Orono. 2.The Cit>' will promote rehabilitation of existing older or substandard rural homes. Rural Orono contains a significant number of older homes, which also require repair, energy conservation measures or major rehabilita ­ tion. These rural owners also require the same type of assistance often reserved for urban areas. Therefore, the City will promote private and subsidized publie rehabilitation efforts in both urban and rural housing improvements programs. CMP 3C - 24 i HOUSING fMPROVElVfE?ff ArXION PI AN Orono's Housing Improvement Plan is a set of implementation policies designed to achieve the above stated Housing Goals and Planning Policies. As has been indicated, the dominant land use in the City of Orono is primarily that of single-family residential homes. There is very limited industrial-commercial development or opportunities for employment and shopping within the City. Orono residents have always relied on the historic town centers in adjacent communities for shopping as well as employment. The general lack of commercial and industrial development and the limited availability of city services such as municipal sewer, water and mass transit will limit the opportunities for, and make it difficult, if possible at all, to provide opportunities for new subsidized h o using de velopinciits anywhere life-cycle and afford able housing in Orono. On the other hand, there are deteriorated and dilapidated housing units located throughout the City. Most of Orono's urban dwellings have been upgraded from seasonal cabins through either private or public rehabilitation programs. Others remain in need of attention. As-stated in the Metiopuli tan Council's Development rramewoi lc Guide, ^'liiipiuviiig A top priority in Orono must be improving the housing conditions of persons who are presently inadequately housed and eliminating substandard housin g must be a tup concern". Thus, rat.her than pursuing construction of new subsidized life-cvcle and affordable housing units in the City, Orono's Housing lmprovemeiit Actioii Plan is aimed principally at improving the condition of Orono's older homes, both urban and rural, and improving the housing conditions of Orono's many low, moderate and fixed income residents. Orono will encourage community pride. Private initiative has always been a characterstic of Orono residents. Programs will be pursued to encourage continuing maintenance and upkeep of all properties and to promote the privately financed rehabilitation of older and under-used properties. 21 Orono w ill participate in housing rehabilitation subsidy programs. Many Orono residents, both urban and rural, are occupying older housing that has code-related structural, safety or health hazards, substandard living conditions or energy inefficiencies. They would like to improve their housing condition and their neighbor; •' .od's appearance, but are unable to because of insufficient income. In man^ eases, older couples are forced to choose between heat or food or leaving their place of long residence. Orono will continue to actively participate in L .<inniunity Development Block Grant and Minnesota Housing Finance Assistance programs designed to help these citizens meet their veiy immediate housing n.- Is. CMP 3C - 25 I I ^ i r 1 ^ • t m I I I I I I I I I [ r I 36. Orono will promote energy conservation methods and procedures. The Building Inspection Department will actively keep abreast of all new systems and products and will assist all homeowners in auditing and improving the energy efficiency of their homes. Orono will actively pursue and advertise all available programs for energy conservation funding. 4r 53. 62. ?4. Orono will subsidize land costs for certain new low and moderate income housing opportunities. Zoning variance s will be granted whenever reasonabl e to allow use of existing urban lots for new moderate income pro^'idi L h ousing.-Tax*f orfeited lots will be purchase d for resale at cost to min imal cost property for th e cons truction of low and moderately pneed h ousing: Orono wiH may encourage developers to provide a variety of housing types and cost ranges. Whenever a multiple family or clustered housing development is proposed, Orono will actively encourage setting aside a reasonable number of units for large families and/or for low and moderate income families. Orono will participate and assist developers in applications for loan guarantees or other suitable forms of housing subsidy aids which may be available. Orono does not hav e suitable land for extensive new development and therefore will not individually pursue nc"vv construction subsidy programs. In addition. Orono is philosophically opposed to rcgrcssi\ c subsidy programs that place ex.^cssivc burdens or debts on future la.\payers. There fore. Orono will be extremr.ly reluctan t to participate in long term or open “cn ded programs such as 1 lUD Section 8\ Orono will cooperate with neighboring cities to fulfill area-wide housing needs. Most apparent is the need of manv etderlr senior Orono residents who desire to live in the immediate area, but who cannot find available elderly senior housing. Orono will actively participate with nearby municipalities tn poolin g of quotas;-allocations, bonding capacity , subsidy dollars and/or staff ex pertise in order to work toward jointly providing cost effective elderly senior housing at locations that are near to home yet also convenient to necessary shopping, transportation and medical facilities. Housing construction will be subject to uniform state building code requirements but will not be burdened with unnecessary zoning requirements. Orono does not intend to require arbitrary minimum dwelling sizes or minimum amenity installations as these artificial standards only drive up the cost of housing while limiting the buyer ’s freedom of choice. Zoning standards for lot area and lot density will be based strictly upon environmental concerns and public facilities availability. Zoning performance standards will be based upon minimum health and safety standards such as fire protection and open space availability. State Building Code performance CMP 3C - 26 E standards will be enforced to ensure structurally sound, weather resistant buildings providing adequate health and safety protection for the future occupant and for the general public's welfare.

TRANSPORTATION PLAN I I I I I I 1 INTRODUCTION Transportation services and facilities arc important elements in the community's ability to accommodate expected development. This plan is a refinement and updated version of the transportation policies adopted in the 1974 Orono Village Comprehensive Guide Plan and the 1980 Orono Community Manaaement Plan. The Plan reflects the growing'energy awareness of the region and its significant effect on commuter practices as well as reflecting the current long range plans of the Minnesota Department of Transportation and the iV'letropolitan Councrl as regards exp ected transportation facility improvements chamtes in the nature of Metropolitan Area development expansion since the late 1970's, as well as the current short and loutz ranee plans of the Minnesota Department of Transportation. This Plan is prepared and presented for the following purposes: 1. 2. The transportation plan is intended to be a management tool for City ’ oHIeials, City ’ staff, and other parties involved in providing, managing and maintaining a transportation system in the city ’ sufficient to accommodate the needs of Orono citizens while also addressing regional transportation needs. 1 he content and direction of the Transportation Plan is based upon our environmental protection commitment and our expected development position within the immediate Take Minnetonka Area and within the fwin Cities Metropolitan Region as a whole. For this purpose, the Transportation Plan contains goal and policy statements consistent with the overall planning objectives of the City; it reviews the existing roadway system and the type of usage it receives; it reviews environmental and land use considerations; and it includes plans for accommodating future transportation requirements for travel both within the City and within the region. This plan is the transportation element of Orono's Community Management Plan, designed to address and conform to all the applicable provisions of the Metropolitan Council's Development Framework C-hndc RecMonal Blucnrint. For this purpose, the Plan's inventory and planning considerations include sulficient detail to explain how Orono’s plans and facilities are consistent with those of neighboring municipalities and with the metropolitan facilities of the region as a whole. This purpose and content is consistent with the City ’s Community Management Plan, with the requirements of the 1977 Mandatory Land CMP 4A - 1 I Planning Act and vvith-thc4ocal "systems statement ” issued to Orono by the Metropolitan —Council and with the Metropolitan CounciPs 1996 Transportation Development Guidc/Policv Plan . I I I SCOPE The time framework of the Transportation Plan is intended to be consistent with the regional planning period of 19 80 through 199 0 2000 through 2020 . and with the City's permanent planning policies for rural Orono and for environmental protection of Lake Minnetonka. The goals, policies and proposed transportation plans contained in this chapter are set in the context of the legislative mandate to plan for regional needs through the year 1990 2020 . In addition, Orono’s long range land use plans call for permanent maintenance of the existing low density rural residential areas. There is to he no staged growth plan, no expansion of the existing urban service area, and therefore, no significant increase in the transportation requirements to serve Orono residents . Because of Orono's environmental protection commitment and because of the location of County Roads 15 and 19 so close to Lake Minnetonka, this Plan also includes permanent goals and policies for protecting Lake Minnetonka including providing alternati\'c transportation routes away from and around the lake. CMP 4A - 2 1 I J I I I J I I I I I I BASIC TRANSPORTATION CONCEPTS AND PRINCIPLES The Transportation Plan is an integral part of Orono's Community ’ Management Plan. Although the statistics and detailed policies apply specifically to this one element of community planning, the overall goals and objectives have been derived from joint and concurrent consideration of all communitv planning elements. Therefore, the policy decisions relating to Orono's transportation requirements complement and balance regional plans with local concerns for historic development patterns, environmental protection, fiscal responsibilitv ’ and general land use. The basic responsibility of the City Is the protection of its citizen's health, safetv and welfare. In terms of transportation systems, this means that a street system must be provided for safe access to all developed properties with sufficient capacity to accommodate the expected number of trips generated by the planned land use. Design and construction standards of the system must be flexible enough to accommodate different potential traffic requirements. I rattle control and curb cut regulations will be necessary to minimize or prevent conflicting movements or unsafe conditions. A uniform system of identification must be provided for street names and house numbers to permit etticient location ot properties and particularly to facilitate quick response in emergency situations. Alternative transportation modes must be investigated to provide alternative transportation opportunities to lessen our dependence on the automobile. The City's transportation system must reinforce the land use plan. One of the basic functions of the transportation plan is to reinforce the development policies and the resultant land use plans ol the city. In Orono, this means reinforcing the permanent urban/rural land use goals. This means providing sutllcient capacity for trips between Orono's residential neighborhoods and the commercial centers of Navarre and other lake area municipalities as well as the metropolitan area to the cast of Orono As a pructiwal matter, this means little or no need for expansion of any highways or roads in the city in the fu tu re to serve new development in Orono_; rather, expansion and iinurade of l ake area and reuional transportation corridors will be driven bv the nattem of commuters livimi in communities west of Orono . Ilistorie development patterns have resulted in a city which Is partially urban and partially rural. Development patterns established 100 years ago are responsible for the dual personality that characterizes Orono. The urban areas provide higher density housing opportunities and all of the neighborhood services necessary to support the residents of the City, urban and rural alike. The rural areas provide areas for low density housing and quasi-agricultural activities. The lifestvles are different, the needs and desires of the citizens are different and the requirements for public ser\ ices are different. CMP 4A - 3 Orono is partly in the Metropolitan Urban Service Area and partly in the Rural Ser\'ice Area. The Metropolitan Council as part oF its Reeional Growth Siratetiv has established a MUSA lirrc boundar\- that rings the Twin Cities separating urban and rural areas defininti the urban area, the permanent rural area, and an urban reserve which is expected to be converted from rural to urban over the next 40 years . Within the MUSA area, metropolitan facilities, including more extensive transportation systems, will be provided for urban development. Outside the MUSA area, in the Permanent Rural Area, developed density is expected to be low and metropolitan facilities and capacities will not be provided. Map No. 6 indicates th e actual location t)f th e boundaiy between th e Urban Semce Area ar.d th e Rural- Service Area as it-passes th rough Orono. In the past the Metropolitan Council's broad-brush maps have shown the MUS.A boundar\- to be running throiuih Orono dividimi our Citv into Urban and Rural sections. While the current MUSA boundary does divide Orono. the illustrative 2020 MUSA shown in the Regional Growth Strategy places all but the northwest tip of Orono within the MUSA, and virtually all of Orono is shown within the MUSA bv 2040. Urban and rural neighborhoods require differing levels of public ser> ices and facilities. The urban areas of Orono have sufficient density to require and to financially support, municipal services such as a typical urban roadway network. The rural areas, on the other hand, have limited density and have environmental restraints prohibiting urban density encroachments. The planned rural densities do not require extensive public roadway systems nor can these rural densities support any type of mass transit system. I RH-DO THE FOLLOWING SIMILAR TO LAND USE SECTION LANGUAGE- Recent changes in national priorities, population trends, metropolitan plans, and metropolitan facilities reinforce the planning and development objectives of Orono. The 1950's and 1960's were years of great expansion and reliance upon the powers of science and industry' to solve all problems. Population graphs showed growth projections running off the paper. Suburbs boomed while core cities were lighting for their vcr>' survival. The 1970's brought a new en\ ironmental awareness and an understanding that nature, not science, was the key to our planet's survival. New social concerns revived the cities and showed how characterless the suburbs had become. Inflation and population stabilization brought unlimited expansion to a halt as roads, schools, and all public services began scrambling for maintenance dollars while overbuilt facilities quickly became tenible taxpayer burdens. The cost of energy is dramatically refocusing every one's attention on conservation and carelul planning of anv new facility. CMP 4A - 4 I I I The results of these changes on the Twin Cities region and on Orono are significant. Orono's ultimate population projections have been dropping from estimates of 37,000 made in 1970, to 23.000 in 1972, to 14,000 in 1974, to the Metropolitan Council's most recent figure projection of 11.000 made in 1979. Population trends durme the last 20 years and a careful analysis of development capabilities of remaining land as compared to Orono's current zoninu, suggest an ultimate oooulatiL ti of around 9,400. This figure is verv- close to our existing estimated population of 7.300 7,800 . and is still probably potentially high considering the new ener gy pro blems and our recent growth trends,—The 11,000 populati on projection and would be easily obtainable within our existing land use planning and zoning densities.

(?) Hie projected population is in line with Orono's rural land u.se preservation policies and with the proposed public facilities plans of Orono. the State Department of Trimsportation and the Metropolitan V\’aste Control Commission. CMP 4A - b I I Changes in population trends and projections have brought on modifications in metropolitan facilities affecting emr Orono’s transportation planning. Regio nal re%%’er~facilities capacities have chang ed drastically. Qnginal plans called for sewering all of Orono with capacity for 37.;060 people. But the final Orono-LuUg Lake~Interceptoi vvas leloeated and is in place with a design capacity for less than 8.400 Orono residents and a service area limited to the existing urban and lakcshore neighb orhoods. In addition, regional transportation plans have been chang ed as commuters mo\'e in toward the center cit%*. 1 he State ot Minnesota has dropped plans for rclucating and e.x panding llig hwas-12 through -Orono as had been .sho^^n in our 19 74 Comprehensive Guide Plan. Interstate jQ4 may be built between Minneapolis and Interstate* 494. but there are no plans tor additional idinu of State-Hiehwav 12 west of Wayzata. Indeed. -Ilig hw-a}-13 wasttpgr resurfaced-in 1978 after statewide priorities shifted from lIighwayl-2 to Highway 212 as the major east»west arterial forccntral Minnesota: As a result of Orono’s low-densitv land use plan, metropolitan sewer facilities capacity allotments for Orono were significantly reduced in the late 1970's. In addition, while as of 1980 MnDOT plans for relocating Hielnvav 12 had been shelved. Interstate 394 became a reality from Minneapolis to 1-494. providinu improved commuter access for the western suburbs. .Although Hiehwav 12 was resurfaced in 1978 after statewide priorities shifted from lliuhwav 12 to Hiiihwav 212 as the major east-west arteial for central Minnesota, in the late IQSO's pressure from outstate intere.sts auain brought focus onto Hiuhwav 12 as a vital transportation corridor. .Additionally, as residential development leap-frogged past Orono to the far western suburbs and into Wright Countv. commuter traffic on Highway 12 through Orono has created high traffic counts and backups that eventually add traffic to parallel corridors such as County Road 6. The increased ‘througir traffic has had significant effects on transportaion plans for Orono and Long Lake. Orono's coninicrcial and economic development have always been centered in the historic town centers. I hc shopping, employment, educational and social needs of Orono residents have been more than amply met by commercial facilities and shopping centers located in Na\arre and in surrounding communities. Rural and urban residents alike utilize these tacilitics and in fact, the commercial stability of the neighboring cities relies in part upon the regional service area that includes all of Orono. Orono's transportation plans there lore As a result, Orono s transportation plans address not onlv the efficient movement of commuter traffic through Orono. hut also the local service needs of our residential neighborhoods and the transportation links between these neighborhoods and the established town center commercial areas. I I I 1 I I J CMP 4A - 6 I I 1 1 I I I A principal goal of Orono's planning program is the protection of natural resources and environmental amenities, particularly the water quality of Lake Minnetonka. This goal has its most profound impact on Orono's land use policies and is therefore indirectly linked to transportation concerns. The most direct connection, however, is that occasioned by County Road 1 5's location along Lake Minnetonka's shoreline. As the western Lake Minnetonka communities have grown and developed they have generated more commuters and the resulting traffic on County Road 15 has increased significantly. Yet there is no room to e.xpand the road without filling into the lake or removing a significant number of lakeshore homes. Any increase in road size, or any appreciable increase in roadway use, will only create an intolerable barrier between these homes and their platted riparian shoreline. Thu s-.-Qrono's Orono maintains a deep concern for finding alternative routes for these commuters in order to protect Lake Minnetonka and to preserve shoreline amenities, landowner's property rights, and the general public's ability to e.xperience a slow-paced journey along Lake Minnetonka's most scenic and most accessible shoreline. Mass transportation alternatives are scarce in Orono and other Lake Minnetonka cities. Region-wide, mass transit has been the neglected stepchild of the post-war auto boom. Lver since Minneapolis's last streetcar ran in 1954, the only public transit has been a less than adequate bus system supplemented by e.xpensive taxis. Metropolitan fransit Authority control of the bus network has increased service lev els including the prov ision of regularly scheduled routes through Orono. This serv ice is provid ed through Navarre and most of our more densely populated urban neighborhoods, but schedules are spread out and off»peak-serv ice is minimal. MetroTransit. which operates the Twin Cities metropolitan mass transit system under the auspices of the Metropolitan Council, provides a limited level of express bus service to the Navarre, and Long Lake areas. While most of Orono's more densely populated urban areas are served bv the express routes, schedules are spread out, and off-peak ser\ ice is limited. Orono residents do have the option of using Park-and-Ride facilities in Navarre or Wavzata. Rural Orono. however, has no direct bus service. A new experimental Tonkamobilc tixcd timc-flcxiblc route seivicc is being tried in 1 9 80. Th is serv ice will fill a prev ious voi d of .serv ’icc bet ween Nava rre and nxcel.sior. but additional serv ice withi n Orono is still to b e desired. 0 CMP 4A - 7 I Rail transit or light rail transit alternatives deserve renewed-invcstigaliuii. Th ere has -been no rail passenger service to Orono since th e last train from Mound ran in 1958. At one time up to 18 trains da ily ran on ho urly he adways between ^^ft)ttnd and Minneapolis %vith five stops inside Orono and t\%~enty Tninine service to d cn\Tito\\T>. Th e increased population of th e lak e area, th e- increasing energy problonis, the incrcasinjily crowded roads and the decreasing roadway niuintonancc bnd g ets all—combine—to—make —the —time—ripe—to reinvestiga te—ah emative transportation mode s such as ligh t rail transit utilizing th e existing under-used uil right-of“\vay th rough urban Orono. Light rail transit seizing the western suburbs deserves renewed investigation. There has been no rail passenger service to Orono since the last train from Mound ran in 1958. At one time un to 18 trains daily ran hourly between Mound and Minneapolis with five stops inside Orono and twenty minute service to downtown. The potential exists For a light rail corridor along 1-394 which would provide an alternative to commuting via bus or passenger automobile. Rail freight service operates along both of Orono's Burling ton North ern existing rail lines. Main line serv'ice is provided on the east west Burlington Northern line along Highway 12 past the Orono Industrial Park. Local freight service operates week ly regularly between \Vav7.ata and Hutchinson on the branch line paralleling County Road 15. although no Orono properties arc ser\ed because this line traverses residential neighborhoods in Orono. The Citv is reviewing the possibility of conversion of this rail line to a regional trail. Orono's trail system provides recreation opportunities as well as local transportation alternatives. As part of our recreation-open space plan. Orono is proposing has developed and is imnlementing an extensive road-side bike-hike trail plan link ing th e commercial area-of Navarre with Spring Park . Tonka Day (and-Lxcelsior) Wayrata. Long l;ake and most of Orono's urban neigh borho ods providing links between both local and regional recreational and open space areas, as well as links within the urban area for pedestrian and bicvcle access to Orono's Navarre commercial area. Besides offering walking and bicycle recreation, this trail system provides an excellent local alternative to auto travel between home and shopping or friends. In addition, the DNR's Luce Line Trail provides extended east-west linkage between several other cities and between several of Orono's north-south bike trails. Taken together, these trails provide a cohesive network of alternative local transportation routes. Orono's air transportation involvement is limited to seaplane operation on Long l.ake and Lake Minnetonka. Orono is not within any metropolitan airports search area and Orono is not within the normal landing or takeoff flight pattern of any regular airport. Maple Plain has a small Held (?) south of that City used by private planes that ma\ fly over northwest Orono on one runway pattern, but there is no adverse effect from the current usage level and the location is such that there are no special land use or height restrictions necessaiy’. I I I I 1 1 I I t I CMP 4A - 8 I I I All of Lake Minnetonka is open for sea plane usage except for the restricted bays of French Lake, Forest Lake and Tanager Lake (?). Sea plane usage has been generally very limited although the potential for conflicts on crowded bays does exist. The most critical problem to date, however, has been one of noise associated with sea plane takeoffs at odd hours. This has been occasional enough so as not to warrant any significant policy formation in this Plan. Completion of the Highway 12 Bypass (?can wc find a better name for it) system to accommodate ^through ’ commuter and commercial traffic is the most significant factor in long-range transportation planning for Orr^no. The Highway 12 Bypass is intended as a two lane freewav connection between western Orono and the current multi-lane U.S.12 /1-394 freewav terminus east ot Long Lake. The Bypass has become necessary due to the severe bottlenecks on current Highway 12 due to signal iyntion at 4 kev intersections and the ever increasing volume of traffic ilowi ng .Srough Long Lake and Orono. Completion of the Bvnass is expected to r-o vide relief for existing Highway 12 as well as its northerly parallel route. Countv >-'oad 6 which has seen tremendous peak hour volume increases as Highway *2 has become clogged. Completion of the Bypass is expected to increase use of the Ring Route, a connection between Countv Roads 6 and 19 along Orono's western border constructed in the carlv 1980's to provide an alternate to Countv Road 15 for the downtown commute from western Lak e Minnetonka. Roadway maintenance concerns arc perhaps the second most significant factor in long range transportation planning for Orono. Every level of government has been increasingly faced with skyrocketing increasing road maintenance pro blems challenges . Initial construction costs are significant, but the maintenance problem is never ending. Vehicle weights have been increasing, speed has been increasing, and winter safety solutions have caused rapid deterioration of roadway surfaces and bridges. At the same time, maintenance budgets are crimped by inflation, the rapidly rising cost of asphalt, and limited maintenance fund income. This crunch is most severe at the local level where levy - limitations prevent impede the hiring of sufficient maintenance crews or the leplacement of well-used equipment sufficient expenditures for road repairs . Thus, the planning concerns for new roadways include not only the initial cost-benefit question, but also the worr y ab o ut issue of spreading future maintenance capability beyond the reach of limited views or limited budgets. CMP 4A - 9 y LAND USE IMPACTS ON TRANSPORTATION As density of residential development increases, the demand on local and collector streets similarly increases. However. Qrono's commitment to low- densitv residential development for protection of Lake Minnetonka, and the concurrent infrastructure limitations that functionally and hv desitzn prevent commercial expansion into the 80% of Orono that is zoned tor low-density residential uses, have resulted in a level of development that does not require major additions to or expansions oF the existing local and collector street system. The maiorin of Qrono’s existing collector road system was established many decades ago to ser\c the separate needs of the Cit> ’s hvo priman historic land uses. The straight-line road tirid system in central and northern Orono was established alomi section lines a century ago to efficiently serve the auricultural activity in the Citv. This tirid has rcadilv adapted to use as a collector system for the many local and private roads that have been created to serve new rural residential subdivisions in the last 30-40 years. l.ikewise. the seasonal recreational uses that iirew up along Qrono ’s 40 miles of l ake Minnetonka shoreline a centurs' atio resulted in a network of windinu roads that commonly followed the center of the narrow peninsulas between bays, creatimi local road frontaee tor lakeshore lots while also often servinu as the main road between settlements. One significant result is that manv existirm homes have their onlv access directly to the collector roads rather than to local streets. Manv of these collector roads have over time evolved into minor arterial roads based on their level of use: the increased traffic is incompatible with direct individual driveway accesses, and elimination of individual accesses is virtually impossible in many locations. County Road 15 ;s the primar\- minor arterial for commuter traffic throuah southern Orono. Because County Road 15 abuts the shoreline alona much of its route, the Citv is committed to retaininii its character as that of a scenic parkway servine local residences. Such a character is incompatible with its minor arterial function. It would therefore be preferable to reduce the volume of tralfic on County Road 15 bv providing an additional east-west corridor in southern Orono,. However, the confiuuration of Lake Minnetonka ’s bavs and the severe topography between them, as well as the laree number ot wetlands in the shoreland areas, preclude the development of such a corridor. I CMP 4A - 10 I I I TRANSPORTATION GOALS AND POLICIES Orono's Transportation Plan is based upon the following goals and policies which are designed to be consistent with our regional responsibility for coordinated transportation planning, and with the goals, policies, and plans of the other elements of the Community Management Plan. TRANSPORTATION GOALS 1. 2. 3. To provide an adequate, safe transportation nehvork sufficient to ser\ e the needs of all Orono residents. To provide a coordinated transportation system providing alternative modes and travel choices for most Orono neighborhoods. Extend bus ser\’ice to Old Crxstal Bav Road and Highway 12 to serve commercial/industrial areas and planned higher density residential development. To provide a coordinated plan for lake area transportation which will satisfy both economic and environmental concerns. 4.To achieve the above goals w ithin the financial capabilities of the Cit>‘ and its citizens. GENERAL TRANSPORTATION POLIC IES 1. 2. Commuter and general arterial traffic must be directed away from Lake Minnetonka. County Road 15 has become the "Main Street" of the Lake Area primarily because of habit and the lack of alternative routes. Shoreline Drive was originally built as a militaiy road in the 1860’s. The road provides the only access to Minnetonka Beach and to many Orono residences. Meanwhile, traffic has increased substantially to where the road is crowded because of commuter traffic. The sensitive en ironment of Lake Minnetonka, and the property rights of the riparian landowners, are being damaged by continued reliance on this outmoded roadway location. Orono will actively promote use of the Ring R«)ute concept and the Highway 12 Bypass to provide viable efficient alternatives to continued over-use of County Road 15. Ihc Citv' has constructed one link in this~sv ‘stcm which already ha.s reduced travel time by up to ten minutes between Mound and—Way rata:—With additional linkages and IiiteI section impiv»v emcnts, a ti aiir»poi"tation voiiidor can be dev eloped to handle the majority ot truck traltic and commuter tiips from the Westonka CMP 4A - 12 I I I a rea while Tclieving the strain fro m Co unt>‘ Ro ad 15. In 1980 the City constructed the first link in this system, the McCullev Road connection between Countv Road 19 and Countv Road 6, In 1998 Orono worked with Hennepin Countv to provide for nonstop eastbound access from McCullev Road to County Road 6: and the final link will be direct nonstop access from County Road 6 to the Miahwav 12 Bvpass. This svtem will provide an eri'icient corridor tor handling a substantial share of the truck traffic and commuter trips from the W'estonka area while providinu a viable alternative to Countv Road 15. Thus, in one motion, thru-traffic movement will be increased in speed and safety while environmentally sensitive areas will be protected from deuradation. 3. I I I I I I I I I 4. Orono will actively promote a scenic parkway system to designate those roads traversing environmentally sen: itive and scenically attractive areas. The intention of the scenic parkway system is to provide a special designation connoting the typically narrow, curvy, slow-speed character of these roads. Scenic parkways provide special vistas of Orono ’s natural amenities and are best suited for rela.\ing unhurried travel. High \ olumc traffic, commuter traffic, and commercial traffic is not appropriate on scenic parkways because these u.sers do not benefit from the attraction and the physical nature of the road is not conducive to efficient thru-traffic nun cment. Because of natural topographic limitations, scenic parkways will also continue to provide local property access and limited collector road functions. Orono will encourage improved transit systems and investigation of alternative transit modes. Orono will support innovative approaches toward providing transportation alternatives to the private auto. This includes such concepts as pedestrian and bicycle trails. pa ra»tr ansi t. improved bus ser\ icc, and investigation of light rail transit. Orono will support the Lake Minnetonka Conservafi.on District in the control of seaplane operation on I.akc Minnetonka. The e.xisting level of seaplane operation is satisfactory to Orono. The City will support the LMCD in their monitoring of seaplane operation and in any reasonable changes in regulations necessary to prevent .seaplane conllict with the primary boating use of the lake. CMP 4A - 13 I I I r I I I I I I I I I I i i I i URBAN TRANSPORTATION POLICIES 1. 3. 4. 5. 6. Local streets in the urban area will be owned and maintained by the Cit>’. Because the land use and street use density of the urban neighborhoods is relatively high, the City will provide public street access to all urban properties. City responsibility for proper maintenance levels will ensure passable, all-weather streets available at all times for emergency vehicles and for general public ingress and egress. All urban properties should be directly served by the public street system. Urban density development is not appropriate on narrow or poorly maintained private roads. Significant exceptions to this rule are in the case of a planned residential or commercial development having private maintenance personnel, or on sensitive lakeshore lots where two homes could be served by one common private driveway to reduce hardcover and topographical problems. Urban streets will be constructed to urban design standards. Ail urban streets will be paved and of sufficient width to accommodate the number of properties being served. Intersections and driveway aprons will be designed and regulated according to commonly accepted engineering safety standards. Street drainage will be designed to utilize existing natural drainage systems and to avoid direct runoff into the Lake. Curb cuts and driveway locations will be limited for traffic safety. All new curb cuts and driveway locations will be subject to performance standards relating to sight distance, lot width and proximity to intersections or other driveways. All properties will be allowed access, but the number of access points and the location of allowable access will be limited for public traffic safety purposes. On-strcct parking will be strictly limited. No parking will be permitted on narrow streets or at hazardous locations. All urban development must provide adequate on-site parking facilities. The City will pursue additional pedestrian and bike-hike trail facilities. The completion of an interconnected bike-hike trail system is important to the furtherance of alternative transportation incentives. The City will encourage Hennepin County to speedily implement the planned bike-hike trail system along several county roads. The separation of bicycle and pedestrian traffic from vehicular traffic is of the utmost importance in accident prevention. CMP 4A - 14 I 7.The City will promote improved mass transportation services for urban neighborhoods. Orono has established a Park and Ride Transit System. Orono encourages improved bus scheduling and improved ser\dce, especially at off-peak hours. Orono strongly supports the "Tonkamobile" (?) program and encourages expansion to provide improved Excelsior- Wayzata service via Orono's North Shore neighborhoods. I I I RURAL TRANSPORTATION POLICIES 1. 2. Public streets in the rural area will be primarily limited to the existing collector and arterial grid system. The low rural land use density does not require nor can it economically support an extensive public street system. Rural lot arrangements have always been served by the existing grid streets and are capable of subdivision to the planned rural density without requiring additional public street investments. The Ring Route concept utilizes as much as possible the existing rural highway system. The principal corridor for traffic from .Minnetrista and points west utilizes Hennepin County Roads No. 6 and 19 and State Highw ay 12. The City of Orono has constructed a key link betw een County Roads 6 and 19. Additional Ring Route traffic uses the existing north-south collector roads to travel away from the Lake toward these principal travel routes. 3. 4. The City of Orono will encourage all neccssaiy road surface and intersection improvements required to accommodate and to facilitate through traffic on the Ring Route. This will include cooperation with the City of Long Lake in accommodating traffic on Highway 12. Rural residential developments will utilize private road feeders to supplement the existing public road grid. Because of topographical limitations, the historic shape of rural land divisions, and the low^ density of rural land use, most new rural residential lots are best prescrx ed by short dead-end roads running off the existing street system. The low number of dwellings on each road, the dead-end configuration and the scattered road locations make public roadway maintenance excessively costly compared to any public benefit. Therefore, most new rural lots will be directly served by privately owned and maintained roadways. New public streets will be accepted where a "through" configuration provides a general public benetit and'or where the number of residences justifies public maintenance expense. CMP 4A - 15 I I I r I I I I I L L 5. 6. 7. 8. 9. Private rural roadways will be constructed to rural design standards. The City will regulate private road design standards to ensure environmental protection and adequate all weather access to all properties. The type and width of road surface required will vary with the number of residences to be served and hence the amount of expected vehicle usage. The length of dead-end roads will be limited for public safety purposes. The City will guarantee reasonable maintenance levels and public access on all private roads. In the process of approving rural subdivisions, the City will acquire underlying public ingress, egress, and access easements over all private roads. These easements will ensure legal access of the public to all properties served by the private road. Development contracts backed by acceptable forms of financial responsibility will assure that all private roads are designed and constructed according to City approved standards and specifications. The City will further guarantee that all private roads are maintained to reasonable standards at all times through required maintenance agreements and/or homeowner's associations, and that failure of the private group to so maintain their private road will be cause for the City to accomplish needed maintenance and to assess the benefitted properties for the direct cost of such maintenance. Driveway locations and rural street or private road intersections will be limited for traffic safct>'. Rural traffic speed is generally taster than that in urban neighborhoods requiring greater sight distances and a lesser number of intersection conflicts for the same degree ot tratlic safety. Joint use of carefully located private roads will generally be preferred over direct access onto public highways from separate properties. Rural trails arc an integral part of the total alternate transportation system. Rural trails offer access to the Hennepin County Park Reserve Lands from all areas of the City. Rural trails offer horseback riding as well as walking and bicycle opportunities. The City will encourage completion of the planned bike-hike trail system and the private development of rural trails connecting the public trail system with individual rural properties. The City will continue to restrict motorized use of trails within Orono as inappropriate to the trail's basic purpose and as incompatible with adjacent residential properties. The City will not promote mass transportation scr>ices for rural Orono. The planned rural land use density cannot economically support public transit ser%ices. E.xisting bus routes pass through the rural area enroute between Long Lake, Wayzata and urban Orono.' These routes are sufficient to scr\’c Orono's rural needs and will in lact provide additional rural service as the need for additional urban service increases. No new CMP 4A - 16 0 I I I THE TRANSPORTATION PLAN Orono's location on the perimeter of the Metropolitan Urban Sen'ice Area has pretty well dictated that our Transportation Plan will be essentially a plan for streets and roads. Orono has no planning needs for airports and has little planning requirement for mass transit. The principal need is a plan to provide for local movement between residential neighborhoods and commercial centers, and for efficient commuter movement away from the congested, environmentally sensitive lakeshore. The principle components of Orono's Transportation Plan are as follows; 1. 2. 3. 4. Developing the Ring Route concept including designation of collectors and minor arterials to direct traffic away from Lake Minnetonka. Developing the Scenic Parkway concept including designation of parkways for slow-spced recreational access along the Lake Minnetonka shoreline and other scenically attractive routes. Developing the Private Road concept for access to low density rural residential properties. Promoting reasonable levels of public transit service for Orono’s urban neighborhoods including maintenance ot the existing MTC bus routes and investigation of alternative public transit modes for commuter travel to the center of the Twin Cities region. PRIMARY CORRIDORS (Draft discussion in regards to issues/policies regarding each ol the following 3 corridors) County Road 15 Old Highway 12 The Ring Route CMP 4A - 18 ORONO'S ROADWAY CLASSIFICATION SYSTEM A commonly accepted way to describe and analyze a transportation system is through a classification system which indicates different levels of services and different levels of construction standards. This Plan follows the classification system developed and adopted by the Minnesota Department of Transportation as applied to the types of roadways seiz ing Orono. Map No. 14 indicates the classification plan for streets and roads in Orono. This plan is consistent with the regional transportation plans and facilities of the Metropolitan Council, the Minnesota Department of Transportation and the Hennepin County Department of Transportation. This plan is consistent with the roadway systems of adjoining municipalities and wiui Orono's urban and rural land use plans. The following descriptions provide detailed explanations of each of Orono's roadwav classifications; I I I (Add infoiiiiatiuii as to Hennepin Countv ’ r-o-w requirements for various Count> roads, and how those may differ from Orono’s requirements...) » ' PRINCIPAL ARTERIAL A Principal Arterial is a grade-separated, high capacity, controlled access highway designed to move vehicles through an area, not within a community. Principal arterials have no local land use access. I he only principal arterial near Orono is that portion of State Highway 12 that becomes limited-access east of Orono’s eastern boundaiy w ith Wayzata. INTHRMEDIATE .ARTLRIAL An Intermediate Arterial is a controlled-acccss, moderately high capacity highway designed to move vehicles between cities and, in Orono's situation, between the free-standing growth centers and out-state cities west of Orono into the metropolitan area. Intersections are limited and controlled. Land use access is intended to be limited to major traffic generators without direct access to residential properties. State Highway 12 is an Intermediate Arterial through Orono although many access and intersection characteristics are typical of a minor arterial or collector. JURISDIC HON: S I AH- DI-I’ARTMnNT OF TRANSPORTATION RIGHT-OF-WAY WIDTH: MINIMUM 100 FLET FOR TWO LANE HIGHWAY CMP 4A - 19 MINOR ARTERIAL A minor Arterial is a controlled access, moderate capacity street or highway designed to move vehicles within planning subregions and between adjacent subregions. The Lake Minnetonka Ring Route is a minor arterial functioning to move, principally commuters and truck traffic, from the western Lake Minnetonka communities into the urbanized areas of the Twin Cities. The minor arterial route channels traffic away from Lake Minnetonka to State Highways 12 and 55, and in the near future, to a direct intersection with Interstate 494 in Plymouth. Land use access is intended to be limited to major traffic generators and local street intersections without direct access to individual residences. JURISDICTION: HENNEPIN COUNTY DEPARTMENT OF TRANSPORTATION RIGHT-OF-WAY WIDTH; MINIMUM 80 FEET FOR TWO LANE HIGHWAY COLLECTOR A Collector street functions to collect traffic from local streets and move it to neighborhood activity centers or to intersections with minor or intermediate arterials. Local land use access is permitted but is regulated as to location and number with direct access to be avoided whenever alternative local street access is available. Intersections with other collectors are olten controlled with signals or with four-way stop signs. Traffic usage is moderate. JURISDICTION: COUNTY OR CITY RIGHT-OF-WAY WIDTH: 60-66 FEET SCENIC PARKWAY Scenic parkway is a designation and classification used by the Cities of Minneapolis and Saint Paul and applied by Orono to those roads which traverse especially scenic and environmentally significant areas of the City. The scenic parkway is typically a narrow, curv)'. slow speed road which provides access to recreational areas and speeial vistas of scenic attractions. High volume through traffic and commercial traffic is not appropriate on scenic parkways because these users do not benefit from the attraction and because the physical nature of the roadway is not conducive to efficient through traffic movement. Because of environmental sensitivity, scenic parkways cannot be rebuilt into higher capacity collectors or minor arterials without adversely affecting the natural setting, the scenic quality of the road and/or the property rights of abutting landowners. Because of the natural topography of the area, scenic parkways also provide some of the traf fic and local access functions of both local and collector streets. JURISDICTION: COUNTY OR CITY RIGHT-OF-WAY WIDTH; 50-66 FEET I I CMP 4A - 20 LOCAL STREETS Local streets are public streets that function to provide direct access to abutting properties. Local streets carry traffic within neighborhoods rather than through traffic between neighborhoods. Intersections with collector streets are controlled by stopping the local street traffic. JURISDICTION: CITY RIGHT-OF-WAY WIDTH: 50-60 FEET DEAD-END: LENGTH WILL BE LIMITED BY PUBLIC SAFETY CONSIDERATIONS PRIVATE ROAD A private road is a privately owned and privately maintained road, located in the rural area or within a planned development, that functions as a local access street. The City will require that private roads be constructed and maintained to City standards. The City will acquire an easement for public ingress, egress and access to all properties, but the City will allow the property owners to limit normal use of the road to the benefitting landowners and their invitees. Private roads will be located on platted outlets intended for joint and several ownership by all the benefitted property owners. JURISDICTION: HOMLOW'NERS ASSOCIATION WITH UNDERLYING EASEMENT TO CITY MAXIMUM SERVICE: APPROXIMATELY TEN RESIDENTIAL PROPERTIES RIGHT-OF-WAY WIDTH: 30-50 FEET DEPENDING UPON NUMBER OF USERS DEAD-END: LENGTH WILL BE LIMITED BY PUBLIC SAFETY CONSIDERATIONS PRIVATE DRIVEWAY A driveway is a privately owned and privately maintained \ehicle path between the street and private property. Private driveways shall be subject to access permits according to the classification of the abutting street. Private driveways will not be subject to any public easement or access right, but do require recorded private easements where driveways cross an intervening private lot between the residence seiz ed and the street. JURISDICTION:PROPERTY OWNER MAXIMUM SERVICE: I RESIDENCE TYPICAL; JOINT DRIVEWAYS ALLOWED WITH MAXIMUM THREE RESIDENTS PER DRIVEWAY IN RURAL AREAS MORE USERS REQUIRE PRIVATE ROAD STANDARDS DRIVEWAY WIDTH: WILL BE REGULATED WHERE MORE TH.\N ONE USER IS INVOLVED OR FOR PUBLIC SAFETY PURPOSES WHERE THERE IS E.XCESSIVE LENGTH BETWEEN THE RESIDENCE AND THE PUBLIC ROAD Kiuht of Wav Presen ation and Lake Access Management f-add a section here about lakeshore access right-of-wavs. and City’s intent to retain them permanently) CMP 4A - 21 I I I 1 I I I 1 1 1 ] I I I I I J I I I Existing roadway maintenance jurisdictions arc reasonable as they relate the classification plan. The State of Minnesota has appropriate jurisdiction over the only Intermediate Arterial in the City. The Hennepin County Department of Transportation has jurisdiction over the only Minor Arterial designated in the Plan. It is anticipated that Hennepin County will assume jurisdiction in the future over the City-built Ring Route link between County Road 19 and County Road 6. Hennepin County has jurisdiction over most of the designated Scenic Parkways which is appropriate in that these roads serve as access to Lake Minnetonka and to County maintained landings for many County residents who do not reside in Orono. The City has jurisdiction over those Scenic Parkways that are away Irom the immediate lakeshore, including the access road to the Orono Golf Course The City has appropriate jurisdiction of most of the Collector and all ot the local streets which serve all Orono residents. Certain key street segments have been designated for Municipal State Aid construction assistance, including: OLD CRYSTAL BAY ROAD from County Road 6 to Fox Street, County Road 84 WILLOW DRIVE from County Road 6 to State Highway 12 and from the Long Lake border to Fox Street FOX STREET from Willow Drive to County Road 146 McCulley Road (Ring Route link) between County Road 6 and County Road 19 (UPDATE AND ADD TO THIS LIST) Finally, individual property owners have appropriate private jurisdiction over those Private Roads serving only their individual properties. I I i I PUBLIC TRANSPORTATION SERVIC ES Map No. 15 indicates the existing extent of public transit serv ice »n Orono. fhe most frequent service is provided on Shoreline Drive through the neart of the Navarre commercial area and closest to the greatest number of Orono ’s urban residents. Commuter frequency service is provided through the remainder of Orono's urban area and the experimental service provides flexible-route service to loeal urban neighborhoods. Existing rail facilities provide the potential for future public transit and for future industrial freight service. The branch rail line through southern Orono once had frequent passenger .service to Minneapolis and has the potential for CMP 4A - 22 renewed service as a part of a region-wide alternative light-rail transportation system. The main rail line through northern Orono has immediate potential for providing direct rail freight service to the Orono Industrial Park should such service ever be desired by one or more of the industries located there. The proposed recreational trail system offers alternative transportation facilities. The complete bike-hike and recreational trail system is described in Chapter 8 and is shown on Map No. 16. These trails provide a coordinated alternative to auto transportation for local trips by almost all Orono residents. Bicycle and Pedestrian Facilities (Draft discussion regarding City/County bike-hike trail system plan and how/whether this relates to Scenic Parkway roadway classification) I I I 1 1 1 ] ] ] I I I r I I L EXPECTED TRANSPORTATION IMPROVEMENTS (ENTIRE SECTION NEEDS UPDATING) No major changes or improvements are expected in Orono's public street system. The existing public road grid system is properly located and of adequate capacity to serve all of Orono's expect: j rural developments without new public street requirements. New rural resiJ.v-ntial developments are expected to rely entireh' on private roads where new access is required by new lot arrangements. In the urban area, a few short local street extensions may occur within the next ten years. Map No. 11 indicates forecast urban development in three locations each of which will probably be ser\ed by a new' public street cul-de-sac. No new urban collector capacity will be required because of the limited number of dwellings in these developments. Orono's major forecast street improvement was the construction of McCulley Road as a link in the Ring Route between County Road 6 and County Road 19. This entirely new road is expected to be completely finished early in the summer of 1980. !!!REVISE THE FOLLOWING PARAGRAPH!!!!!!! The State of Minnesota does not expect to improve or relocate Highway 12. When the 1974 Orono Village Comprehensive Guide Plan was prepared, the State Highway Department was reviewing plans to relocate and upgrade Highway 12 into a principal arterial. These plans have now been completely dropped from State planning consideration at least until after the year 2000. The only physical improvements scheduled or expected are as follows; — THE FOLLOWING SECTIONS NEED MAJOR UPDATING ™ OLD CRYSTAL B.\Y ROAD INTERSECTION - Scheduled to receive turn lanes and traffic signals in 1981. Orono actively pursued this project and heartily recommends early completion because ol the heavy school traffic and school bus traffic utilizing this i'^tersection. COUNTY ROAD 6 INTERSECTION - Scheduled to receive turn lane improvements in 1980. This intersection has many turning movements complicated by an odd street crossing, a closely located rail crossing, and poor sight distance to the east. Orono encourages early completion of this work to facilitate improved Ring Route traffic safety. Orono encourages further planning for improvement in the sight distance and for possible signaling or rail crossing changes to further improve traffic movements through the intersection. CMP 4A - 24 Hennepin County is undertaking bridge improvements affecting traffic in Orono. Improvements have been completed on Tanager Lake Bridge, Boy Scout Bridge, Noerenberg Bridge and Coffee Bridge. Areola Bridge is scheduled for major redecking work in 1980 and 1981, The Narrows Bridge and Hendrickson Bridge are scheduled for work in following years. While essentially of a maintenance nature, these are major construction jobs requiring partial or total bridge closure. Therefore, Orono and adjoining municipalities ha\e been deeply in\olved to assure reasonable traffic flow and emergency access during the construction. In addition, Orono is concerned that all bridge alterations provide completed roadways of a width compatible with our scenic parkway plans including provision for adequate walking and bicycle paths over the channels. Mound and Spring Park arc contemplating changing their portion of Counh' Road 15 to four lane width. This does not directly affect Orono, but does have the indirect complication of increasing traffic flow toward the center of Lake Minnetonka. Orono is opposed to any widening of County Road 15 within Orono. Orono would like to discourage widening of County Road 15 at any location. Instead, Orono is encouraging completion of the Ring Route concept to take traffic volume off of County Road 15. thereby effectively inereasing its local service capacity. The completion of a two lane ring route connection north from Mound to McCulley Road in Orono will greatly reduce travel time to Wayzata and will be consistent with the transportation needs of the Westonka Area and the transportation plans of Minnetrista and Orono. Orono further encourages the development of a new or improved connection south to Highway 7 for areas west of Orono as another alternative commuter link to the metropolitan area.
