WETLANDS PROTECTION DIVISION 1. GENERALLY Sec. 78-1601. Purpose and intent. (a) The purpose of this section is to recognize, preserve and protect the environmental, aesthetic and hydrologic functions of the city's wetlands by regulating the use of wetlands and their adjacent properties in conjunction with the goals of the environmental protection plan within the community management plan. These functions include, but are not limited to, sediment control, pollution control, filtration, fish and wildlife habitat and aquifer recharge. The surface water management plan will provide guidance for stormwater treatment requirements and wetland restoration opportunities in order to protect the integrity of wetlands. (b) The intent of this section is to protect wetlands to the maximum extent possible while allowing a reasonable use of the property. This section adopts the regulations and standards of the Wetland Conservation Act of 1991 (WCA), Laws of Minnesota 1991, chapter 354, as amended, and the rules adopted pursuant to the WCA. It also establishes a wetland overlay district. This overlay district further regulates the underlying land use as allowed by other districts or the WCA. (c) This article applies to, and wetland buffer areas must be created or existing buffer areas must be maintained around, a protected wetland located partially within, wholly within, or directly adjacent to the property in the following situations: (1) When the wetland is required to be replaced or restored, or when the wetland is being altered; (2) When new development occurs. For purposes of this subsection, new development means: a. Any subdivision that creates a new lot that has no principal structure on it; b. Construction of a principal structure on an existing vacant parcel of land; (3) When redevelopment occurs that has the potential to adversely impact a wetland. For purposes of this subsection redevelopment means the removal of the principal structure to the extent of more than 50 percent of its market value and volume and reconstruction on the same property. This requirement does not apply if construction is the result of less than 75 percent of the building being damaged by an involuntary force, such as fire, wind, or vandalism; (4) When any construction or land alteration activity that does not fall within the meaning of 'redevelopment' has the potential to adversely impact a wetland. For purposes of this section, "the potential to adversely impact a wetland" exists when all of the following three conditions exist: a. The portion of the property disturbed by construction or land alteration activity drains to the wetland; and b. The amount of grading exceeds 50 cubic yards or the construction activity involves the disturbance of more than 5,000 square feet of area; and c. The redevelopment activity results in a net increase in the square footage of impervious surfaces that drain to the wetland, or results in the relocation of impervious surfaces closer to the wetland, or results in changes to drainage patterns (slopes, meander patterns, etc) that the city engineer determines will increase the velocity or rate of runoff to the wetland. For new development, all wetlands on the property shall be subject to the buffer requirements. For redevelopment or other grading or construction situations that are not new development, only the wetland that is potentially adversely impacted shall be subject to the buffer requirement. In the event that the wetland is on an adjacent property but near enough to the subject property so that buffers to said wetland would extend into the subject property, the buffer requirements apply. (Ord. No. 28 3rd series, § 1, 8-22-2005 November 16, 2011 85 Old Crystal Bay Road S Page 3 of 6 DIVISION 2. DESIGNATION OF PROTECTED WETLANDS Sec.78-1602.Wetland types. The wetlands protected and regulated by this section are types 1, 2, 3, 4, 5, 6, 7, and 8 wetlands, as defined in circular 39, 'Wetlands of the United States", 1971 edition, United States Department of the Interior, unless the wetland is within a shoreland district in which case the more restrictive rules regarding setbacks would apply. Protected wetlands are further defined as follows: (1) Type 1—Seasonally flooded basins or floodplains: Type 1 wetlands are seasonally flooded basins or flats in which soil is covered with water or is waterlogged during variable seasonal periods but usually is well-drained during much of the growing season. Type 1 wetlands are located in depressions and in overflow bottom lands along water courses. Vegetation varies greatly according to the season and duration of the flooding, and includes bottom land hardwoods, as well as herbaceous plants. (2) Type 2--Inland fresh meadow: Occurs along the shallow edges of lakes, marshes and floodplains, or in perched depressions. The soil is usually without standing water during much of the growing season, but is waterlogged within at least a few inches of the surface. Vegetation includes grasses, sedges, rushes and various herbaceous plants. (3) Type 3—Inland shallow fresh marsh: Soil is usually water logged during the growing season, often covered with as much as six inches or more of water. Vegetation includes grasses, bulrushes, cattails, arrowheads, smartweeds and other emergent aquatic vegetation. (4) Type 4--Inland deep fresh marsh: Soil covered with six inches to three feet or more of water during growing season. Vegetation includes cattails, reeds, bulrushes and wild rice. Open water areas may contain pondweeds, naiads, coontail, water milfoils and other submergent aquatic vegetation. (5) Type 5—Inland open fresh water: Water is usually less than ten feet deep and is fringed by a border of emergent vegetation. Vegetation includes pondweeds, naiads, coontail, water milfoils and other submergent aquatic vegetation. (6) Type 6--Shrub swamp: Occurs along sluggish streams or on floodplains. The soil is usually waterlogged during the growing season, and is often covered with as much as six inches of water. Vegetation includes alder, willow and dogwood. (7) Type 7--Wooded swamp: Occurs along sluggish streams, on floodplains, on flat perched depressions and in shallow lake basins. The soil is waterlogged to within a few inches of its surface during the growing season and is often covered with as much as one foot of water. Vegetation typical to this wetland includes tamarack, white cedar, black spruce, balsam fir, red maple and black ash. (8) Type 8--Bog: Occurs along sluggish streams, on flat perched depressions and shallow lake basins. The soil is waterlogged and supports a spongy covering of mosses. Vegetation typical to this wetland type includes sphagnum moss, heath shrubs and sedges. Minnesota bogs contain leatherleaf, Labrador tea, cranberries and pitcher plants. Scattered stunted black spruce and tamarack also are common features of bogs. (Ord. No. 28 3rd series, § 1, 8-22-2005) November 16, 2011 85 Old Crystal Bay Road S Page 4 of 6 Sec. 78-1603. Boundaries of the wetland overlay districts and designation of official city wetland map. This section establishes wetland overlay districts. These districts are subject to additional requirements beyond those required by the WCA. The boundaries of the wetland overlay districts are identified graphically on the official city wetland map (CWM) which is hereby adopted by reference, a copy of which shall be kept on file in the office of the city clerk and shall be available for public review during all normal office hours. Wetlands in addition to those shown on the city wetland map may exist, and may be identified by wetland delineations under WCA rules. If a specific wetland delineation has been done under WCA rules, then the boundaries of the wetland overlay district for that location will be as shown in the delineation. The city may require wetland delineations to determine compliance with WCA rules and to determine administrative wetland boundaries; however, property owners may have wetland delineations done for their properties on their own initiative. The delineation must be done by a qualified professional according to WCA rules and be acceptable to the planning director, who may require review by city consultants or a technical evaluation panel if necessary. Approved WCA wetland delineations must be provided to the city in a hard copy format and a CAD or GIS format in Hennepin County coordinates. The planning director will have the approved WCA wetland delineations shown on the official city wetland map. Public waters are not included in the overlay district, unless a wetland is part of a public water. (Ord. No. 28 3rd series, § 1, 8-22-2005) Sec. 78-1604. Interpretation of wetlands boundaries. Whenever a wetland boundary is disputed or uncertain, the planning director may require the submission of a registered survey of the property and field staking showing the city-designated wetland contour or a delineation of the wetland, and such other information as the director may require in order to resolve the dispute or uncertainty. The planning director may require review by city consultants or a technical evaluation panel if necessary. No boundary change may be authorized on the basis of fill that was placed on the site after the city designated the area as part of the wetland overlay district. Persons aggrieved by a decision of the planning director may appeal such decision in accordance with the provisions of section 78-99 of this chapter and the WCA rules. (Ord. No. 28 3rd series, § 1, 8-22-2005) DIVISION 3. BUFFER AREAS Sec. 78-1605.Wetland buffer areas. (a) This subsection establishes requirements for wetland buffer areas around protected wetlands. Buffer areas are necessary and beneficial to maintain the health of wetlands. Buffer areas protect the edge of wetlands from erosion while filtering sediment, chemicals and other nutrients from runoff that drains into wetlands. Buffer areas can improve the biological diversity and health of a wetland environment while reducing the adverse impacts of human activities. (b) Buffer areas regulated by this section are areas of vegetative cover that are upland of the wetland edge, and that occur in a natural condition or through restoration. Buffer areas consist of shrubbery and trees, native grasses and/or forbs that are not mowed, fertilized or manicured in any manner. Mowing, fertilizing, manicuring, or vegetation removal within a buffer area is not allowed unless the city has issued a permit for such activity in conjunction with an approved buffer management plan. (1) Acceptable buffer areas shall have the following qualities: a. A continuous dense layer of perennial grasses that have been uncultivated or unbroken for at least ten consecutive years, or b. An over story of trees and/or shrubs with at least 80 percent canopy closure that have been uncultivated or unbroken for at least ten consecutive years, or c. A mixture of the plant communities described in a. and b. above, which have been uncultivated or unbroken for at least ten consecutive years. November 16, 2011 85 Old Crystal Bay Road S Page 5 of 6 (2) Unacceptable buffer areas have the following qualities, including but not limited to: a. Undesirable plant species (including but not limited to reed canary grass, common buckthorn, purple loosestrife, leafy spurge and noxious weeds), or b. Lacking a layer of organic thatch or duff, or c. Topography which tends to channelize the flow of surface runoff, or d. Is characteristically unlikely to retain nutrients and sediment. (3) Buffer areas which have been broken or cultivated within the past ten consecutive years must be restored to a condition consistent with an acceptable buffer area defined in section 78-1605(b)(1), a restoration or landscape plan must be submitted to the planning director, which restoration shall include, replanting and maintaining according to each of the following guidelines: a. Buffer areas shall be planted with a seed mix containing 100 percent perennial native plant species, except for a one-time planting of an annual nurse or cover crop such as oats or rye. b. The seed mix to be used shall consist of at least 12 pounds pure live seed (PLS) per acre of native prairie grass seed and five pounds PLS per acre of native forbs. Native prairie grass and native forb mixes shall contain no fewer than four and five species respectively. c. The annual nurse or cover crop shall be applied at a rate of 20 pounds per acre. d. Native shrubs and or trees may be used in addition to forbs and grasses. Shrubs shall be distributed so as to provide a natural appearance and shall not be planted in rows. e. Native prairie grasses and forbs shall be planted by a qualified contractor. f. No fertilizer shall be used in establishing new buffer zones, except on highly disturbed sites when deemed necessary to establish acceptable buffer vegetation and then limited to amounts indicated by an accredited soil testing laboratory. g. All seeded areas shall be mulched immediately with clean straw at a rate of one and one-half tons per acre. Mulch shall be anchored with a disk or tackifier. h. Buffer areas (both natural and created), shall be protected by silt fence during construction and the fence shall remain in place until the area crop is established, and at that time the fence shall be removed. (c) Buffer area widths will be based on the wetland protection strategies established in the Orono Surface Water Management Plan (SWMP) (December 2002). A protection classification has been assigned to each wetland in Orono based on the stormwater susceptibility and functional assessment for each wetland. The four protection classifications are described as follows: Protection Susceptibility Rating Description Classification "Preserve" Highly Susceptible Highly susceptible to both quantity and quality impacts from runoff; have the highest degree of protection "Manage 1" Moderately Moderately susceptible to quantity and quality impacts; Susceptible protection is less stringent than Preserve, provides protection to maintain their characteristics "Manage 2" Slightly Susceptible Less stringent protection than Manage 1 wetlands; maintenance of characteristics is desirable "Manage 3" Least Susceptible Wetlands are significantly degraded (e.g., cultivated or canary grass monotype) or lack of wetland characteristics; not typically impacted by runoff; no quantity and only limited quality treatment of runoff is required The protection classification for each wetland will be found on the "Wetland Management Classification Map & List" which is hereby adopted by reference, a copy of which shall be kept on file in the office of the city clerk and shall be available for public review during all normal office hours. The following are the required buffer area widths for each protection classification: November 16, 2011 85 Old Crystal Bay Road S Page 6 of 6 Protection Width of Buffer Area Additional Protection Requirements (B = Bounce = Classification from Wetland Change in water level due to runoff event) (P = Boundary Phosphorus) "Preserve" 50 feet B: Maintain bounce at or below existing conditions P: Limit loadings to predevelopment loading (0.14 Lbs./Ac/Yr) "Manage 1" 35 feet B: Maintain bounce at or below existing conditions plus 0.5 foot P: Limit loadings to predevelopment loadings times 2 (0.28 Lbs/Ac/Yr) "Manage 2" 25 feet B: Maintain bounce at or below existing conditions plus 1.0 foot P: Limit concentration to predevelopment concentrations (200 ppb) "Manage 3" 16.5 feet B: No quantity requirement P: Limit concentration to 225 ppb (d) In cases of new development or redevelopment the city shall require that vegetation in the wetland buffer be installed prior to the issuance of the certificate of occupancy. The city may waive this requirement in lieu of a cash escrow or letter of credit equal to 150 percent of the cost to install the required buffer. (e) The city may allow the disturbance of an existing buffer area during the course of construction activity. This disturbance must be kept to a minimum, soils must be decompacted to a level that will accommodate root growth, and the buffer area must be re-established as required by the city. The city will determine the amount of allowable disturbance. The city may require a cash escrow or letter of credit equal to 150 percent of the cost to re-establish the buffer to its original condition. (f) The city may require buffer area planting and maintenance when the city determines that there is inadequate vegetation in the buffer area to meet the intent of this section. The city may require a cash escrow or letter of credit equal to 150 percent of the estimated cost of the vegetation and installation. The escrow or letter of credit must be valid for up to two years and may be used by the city to replace any vegetation that dies. (g) The affected property owner or homeowner association that is responsible for the maintenance must: (1) Maintain and repair damage to buffer areas from such activities as mowing, cutting, grading or other prohibited activities, unless mowing is approved by the city as a buffer management plan. Permission must be obtained from the city before implementing buffer management plans, which may include mowing, burning, and the use of herbicides. (2) Maintain only the permitted vegetation in the buffer area and must remove all noxious weeds and invasive, non-native species such as European buckthorn, upon obtaining a vegetation removal permit from the city in conjunction with an approved buffer management plan. (3) Ensure that all soil surfaces in the buffer area are planted with the permitted vegetation and that there is no open soil surface that may result in erosion. (4) Ensure that livestock or other domesticated animals which have the potential to permanently disturb the buffer area by compaction or vegetation removal be kept from entering the buffer area and wetland by a fence or other suitable means. (h) The final upslope edge of the buffer shall be provided to the city in a hard copy and in a CAD or GIS format in Hennepin County coordinates. (i) Golf course partial exemption. Public and private golf courses existing and in operation on the date of adoption of this article shall be allowed a partial exemption from buffer creation and maintenance requirements with regards to mowing or cutting buffer vegetation in areas subject to golf play, subject to the following: (1) At such time that this article requires establishment of a buffer, applicant shall submit a certificate of survey identifying the location, size and type of the wetland for which buffer exemption is requested. (2) Applicant shall submit a buffer management plan for city council approval, identifying those areas where exemption is requested and providing for alternative methods of wetland protection equivalent to an unmowed buffer. (Ord. No. 28 3rd series, § 1, 8-22-2005) Memo Stantec Bonestroo To: Melanie Curtis From: John Smyth File: 139-11000 Date: November 14, 2011 Reference: Wetland Code Review —85 Old Crystal Bay Road We have reviewed the City of Orono Wetland Code Requirements for the proposed driveway. The proposed driveway triggers the wetland buffer requirements of the City Wetland Code. The wetland located adjacent to the area of disturbance is classified as a Manage 2 wetland and will require a 25 foot buffer to protect the wetland. A wetland buffer is required for the portion of the wetland adjacent to the proposed driveway disturbance (see attachment). It appears that as part of a Minnehaha Creek Watershed District approval of the house construction, buffers were required around all of the wetlands. The landowner is responsible to deal directly with the watershed to ensure they are in compliance with their previous approval. Buffer Vegetation Requirements Most of the buffer is in a natural state (not mowed or turf) and the ordinance only requires that it is preserved. It appears that a small portion of the buffer may contain turf. The portion of the buffer that is turf will need to have the turf removed and be restored to native vegetation. A written description of the proposed native seed mix to be seeded and method of site preparation and seeding should be provided to the City for review and approval. According to the ordinance Div. 3 Sec. 78-1605 (3) the seed mix must contain at least 12 pounds (PLS) per acre of native prairie grass seed and 5 pounds (PLS) per acre of native wildflower seed. The grass mixture must contain a minimum of four species while the wildflower mixture must contain a minimum of five species. Wetland Buffer Markers At the time of construction staking for the grading of the proposed driveway the upslope edge of the wetland buffer shown on the attached exhibit should be staked so it is clear to the City and landowner where the buffer is located.

The plan was received 11-4-11. We have the following comments with regards to engineering matters: • This property shows a delineated wetland along the south side of the existing and proposed driveway. • The city wetland maps indicate that this is a Manage 2 wetland. The plan shows the required 25 foot wide buffers area. • It is our understanding that past permits generated the necessary buffers, easements, and agreements for the wetland and the plan is acceptable from an engineering standpoint. • This project will disturb more than 100 CY of material. Sediment and erosion control information meeting the requirements of Orono's City Code 79-7(c)(2)must be submitted. The minimum $2000 sediment and erosion control financial security should be required of the owner for this permit.
