NOW, THEREFORE, BE IT RESOLVED by the City Council of Orono, Minnesota: FINDINGS 1. This application was reviewed as Zoning File #1807.. 2. The property is located in the LR-lB Lakeshore Residential Zoning District requiring one acre in area. The property consists of 27,930 s.f. or .64 acres. 3. The Orono Planning Commission reviewed the application on April 19, 1993 and recommended unanimous approval of the proposed conditional use permit and variance as set forth above and based approval on the following findings and hardships: a. The lakeshore yard consists of steep bluffs/banks. Page 1 of 4 TRANSFER ENTERED DEPT. OF PROPERTY TAX 8, PLIOLIC RECORDS JUN 4 1993 F.5W MAde A �Ild F G~/ CITY of ORONO RESOLUTION OF THE CITY COUNCIL NO. Severe erosion of lakeshore bank. Scouring action of waves along west bank of North Arm. Severe erosion will eventually impact mature tree and structural improvements within lakeshore yard if condition is not remedied. The proposed land alterations within the lakeshore yard will not result in additional hardcover. All land alterations will be above the 929.4 elevation. 4. The Council finds that granting a conditional use permit to allow the land alterations as set forth in the amended plan will not be detrimental to the health, safety or general welfare of the public, would not adversely affect light, air nor pose a fire hazard or other danger to neighboring properties, nor will its use depreciate surrounding property values and that the proposed level of use of the property will be in keeping with the intent and objectives of the Zoning Code and Comprehensive Plan of the City. 5. The City Council finds that the conditions existing on this property are peculiar to it and do not apply generally to other property in this zoning district; that granting the variance would not adversely affect traffic conditions, light, air nor pose a fire hazard or other danger to neighboring properties; would not merely serve as a convenience to the applicant, but is necessary to alleviate a demonstrable hardship or difficulty; is necessary to preserve a substantial property right of the applicant; and would be in keeping with the spirit and intent of the Zoning Code and Comprehensive Plan of the City. CONCLUSIONS, ORDER AND CONDITIONS Based upon one or more of the above findings, the Orono City Council hereby grants a variance to Municipal Zoning Code Section 10.55, Subdivision 8 to allow land alterations within the lakeshore protected area and grants a conditional use permit per Municipal Zoning Code Section 10.03, Subdivision 9 as the land alterations involve land movements in excess of 100 cubic yards. This approval is subject to the following conditions: Page 2 of 4 F.500f M*Y �0 �4 CITY of ORONO RESOLUTION _OF THE CITY COUNCIL NO. `y 1. Silt fence must be installed along the perimeter of the shoreline prior to any construction to protect the lake from erosion. 2. Applicant shall file for the legal combination of Lots 1 and 2. This must be completed before the City staff can issue a land alteration permit. Applicant's contractor must obtain a land alteration permit before the work can begin. 3. Authorities granted by this resolution run with the property not with the owner, but are permissive only and must be exercised by application for a land alteration permit within one year of the date of Council approval or this variance/conditional use permit will expire on that date (May 10, 1994). 4. Violation of or non-compliance with any of the terms and conditions of this resolution shall constitute a violation of the Zoning Code, shall automatically terminate any authority granted herein, and shall be punishable as a misdemeanor. 5.

Lund noted that since it was installed they have struggled with ground cover in this area due to erosion. Johnson felt that was not an issue as clay could be compacted and the area sodded. Lund said he would need to confer with the other half of the estate before agreeing. It was moved by Johnson, seconded by Cohen, to recommend approval of Application #1818 for Russell Lund Estate, 905 Tonkawa Road, approving a preliminary subdivision subject to conditions set forth in the staff memo and the removal of the asphalt ramp to the lake in the 0-75' zone on Parcel B.

Mabusth explained at the last review of this request the applicant was asked to confirm the alternate drainfield site and to have surveyor locate the proposed court on the survey. The location of the alternate septic site has been confirmed, and the applicant has: agreed that the tennis court be moved 5' further from the road, maintaining a 17' setback. The structure is also located in front of the principle structure Bellows stated all other issues were addressed at the previous review. Mabusth added they have not received any negative comments from the neighbors. It was moved by Bellows, seconded by Cohen, to recommend approval of Application #1806 for Jon and shirley Bill igmeier, 2935 Farview Lane, approving a street setback variance of 33' and allowing the accessory structure to be placed in front of the principle structure, per conditions set forth in the memo and that there be no outside lighting.

Mabusth explained this application involves major filling and grading in the iakeshore yard to eliminate a severe erosion problem, and to save a 2+ Inch diameter elm tree. She noted the applicant has submitted an amended proposal addressing all of staff's concerns and requests. She said there is no need for further review by other agencies. Sumey presented photos showing the rip rap was in existence. Bellows commended her for quickly resolving issues brought up by staff. Mabusth added this form of restoration is excellent. It was moved by Schroeder, seconded by Peterson, to recommend approval of Application #1807 for Susan Marie Sumey, 1330 Cherry Place, approving a conditional use permit and variance to allow filling and grading in the lakeshore yard. Ayes 5, nays 0. (#7) #1808 JAMES R. ABRAHAMSON, 4630 TONKAVIEW LANE — VARIANCE — PUBLIC HEARING 7:24 — 7:30 P.M. The Affidavit of Publication and Certificate of Mailing were noted. Mr. and Mrs. Abrahamson were present for this application. Weckman explained the applicants request a lot area variance to build a residence on this substandard property. He noted the similar type of development in the area. He added there is no additional acreage that the applicants could purchase. The access easement is provided for this property across Parcel D. Bellows noted this request is slightly below the 80% margin allowed by code without variance approval. Cohen asked if the applicants knew this was an unbuildable lot when they purchased it. Mr. Abrahamson stated their purchase is contingent upon approval of the variance request. He added, a new residence is being constructed on Parcel B. It was moved by Johnson, seconded by Schroeder, to recommend approval of Application #1808 James R. Abrahamson, 4630 Tonkaview Lane, approving a lot area variance to construct a new residence.

Ayes 5, nays 0. (#6) #1810 HENRY DENERO, 1245 SIXTH AVENUE NORTH — CONDITIONAL USE PERMIT — RESOLUTION #3274 Mr. DeNero was present. Mabusth explained the applicant seeks approval of a conditional use permit for a second story guest apartment over an attached garage that has existed for years. Because of the extensive remodeling and because of the kitchen in the guest apartment, the applicant was required to file the application. There is a breezeway that connects the residence to a garage. The breezeway area does not connect directly to a stairs that takes you to the upper level apartment. Access is through a separate door at the exterior of the garage. The fact that this did not meet the requirement of an internal access concerned the Planning Commission. But they also noted the breezeway does not have a permanent foundation, and there is adequate area to support a guest house unit on the property. Jabbour and Goetten disagreed with the Planning Commission's findings. Goetten stated to have a guest house the property must have the ability to be divided and the guest house survive on its own. Mabusth stated the property meets only the area standards for such. Jabbour said if this is to be considered as a guest house, it must meet all required setbacks. 3 To: Mayor Callahan & Orono Councilmembers Orono Planning Commission Members Ron Moorse, City Administrator From: Jeanne A. Mabusth, Building & Zoning Administrator Date: May 4, 1993 Subject: #1807 Susan Marie Sumey, 1330 Cherry Place Conditional Use/Variance - Resolution Additional Exhibits J - Applicant's Addendum K - Amended Land Alteration Plan Brief Review of Application The application involves major land alterations within the lakeshore yard involving filling and grading activities to restore and prevent further erosion of the steep lakeshore bank. The original restoration plan was reviewed by the City Engineer, Exhibit G. The original plan lacked a substructure needed to support and sustain the layers of geo-grid fabric. The amended plan, Exhibit K, has been reviewed by Gustafson and found to meet all of the installation criteria set forth by the manufacturer and as recommended by the City Engineer. The restoration project will involve no hardcover within the lakeshore yard as all the fabric and support structure will be covered with earth. Lots 1 and 2 have not been legally combined. The applicant has agreed to legally combine the two parcels. The resolution has included the required legal combination as a condition of approval. Planning Commission Recommendation The Planning Commission recommended unanimous approval of the amended land alteration proposal. The enclosed approval resolution has been drafted per the findings and conditions of the Planning Commission approval. Please review the Planning Commission minutes of April 19th and the enclosed Planning Commission packet for more detail and background on this review. lsv TO: Mayor Callahan and Orono Council Members Ron Moorse, City Administrator FROM: Jeanne A. Mabusth, Building & Zoning Administrator DATE: April 12, 1993 SUBJECT: #1807, Susan Marie Sumey, 1330 Cherry Place - Conditional Use Permit/ Variance Pertinent Ordinances Section 10.03, Subd. 19 - Conditional use permit required for alterations within lakeshore setback. Application involves the regrading and filling of lakeshore bank to prevent further erosion.

List of Exhibits A - Application B - Plat Map C - Property Owners List D - Hardcover Facts E - Landscape Contractors Description of Improvement Project F - Profile of Fill Area and Tiered Installations of Miragrid G - Shawn Gustafson Report, City Engineer H - Information on Miragrid I - Topographic Survey Zoning File #1807 April 12, 1993 Page 2 Description of Request Applicant proposes the filling of approximately 134 cubic yards of fill to stabilize major portions of the lakeshore bank that is sustaining serious erosion. Major portions of the lower areas have washed downhill to lake. A 24" ehn at the top of the bank will be lost if repairs are not made. In the early '80's the neighbor to the immediate west applied for similar alterations of bank based on similar erosion problems. Both the DNR and MCWD have been asked to review the proposal to determine if permits will be necessary. The DNR will not require a permit review as long as all alterations are above the 929.4. As alterations are proposed between the 930 and 931.5, an MCWD permit will be required. Applicant has been advised of the need to file a permit application. The repair of the bank consists of cutting and filling and the installing of a geogrid fabric in tiered layers and all will be covered over with earth. The enclosed improvement will not result in any hardcover. Please review Exhibit G. Shawn Gustafson has advised that he has contacted the Miragrid manufacturer. In reviewing the proposed plan for installation, the manufacturer concurred with the City Engineer that the proposed use of the miragrid would not be adequate to sustain the bank and that additional anchors and support system would be necessary. The engineer has recommended the following additions and changes in the current proposal: 1. Fill soil must be of a granular material not clay. 2. Fill soil should be compacted no greater than at 6" lifts to minimum specified density of 95 %. 3. Miragrid needs to be anchored to soil bank and suggest use of duckbill anchors set into soil bank and tied to a series of pipes or bars laid parallel to shoreline. Miragrid could then be attached or wrapped around these pipes and anchored to side slope. 4. Seeding with Crown Vetch or other quick spreading plant with good root base. Possible use of permanent turf restoration such as miramat. Gustafson advises proposed American Excelsior Biodegradable turf is temporary and will not prevent future erosion unless adequate vegetation is restored. 5. Rip rap to prevent undermining of restored bank. 6. Silt fence installed along shoreline prior to construction. Zoning File #1807 April 12, 1993 Page 3 Staff has contacted the applicant to review some of the concerns expressed in Engineer's report. Ms. Sumey advises that rip rapping exists at the shoreline except that it has been covered up by the eroding bank. The City Engineer shall inspect the rip rap once it is uncovered. It is imperative that applicant's contractors not cover existing rip rap until a evaluation is made by the City. Staff realizes that the additional improvements to the original plan will result in major increases in cost. Rip rap may be upgraded at a later stage but based on potential of scouring from wave action, the bank restoration may be completely undermined if functional rip rap is not a part of the original improvement. Issues for Consideration 1. Proposed land alterations within the lakeshore yard will not result in additional hardcover. Hardcover excesses exist within the 0-75' and 75-250' setback. Will applicant be asked to reduce hardcover? 2. If members find the current proposal objectional, what other methods are available for applicant to pursue to preserve her lakeshore yard. Statement of Hardship 1. Lakeshore yard consists of steep bluffs/banks. 2. Severe erosion of lakeshore bank. 3. Scouring action of waves along west bank of North Arm. 4. Severe erosion will eventually impact mature tree and structural improvements. Options of Action Approval as proposed; or Approval as amended with conditions; or Denial. ch n 1�0 CITY OF ORONO - GENERAL LAND USE APPLICATION ------------------------- 9'^ -------- ------- PROPERTY LOCATION a 't Site Address 3 30 CAe YV a ��Q C C 01r-7 11 0" Property Identification Number (P.I.D.)

Engelhardt e-- r----- —7- PR 793 We have reviewed the proposed shoreline restoration proposal for Susan Sumey's property at 1330 Cherry Place in Section 8. The property is adjacent to the North Arm of Lake Minnetonka and has a severely eroded soil bank along the shoreline. The proposed restoration is not acceptable from an engineering standpoint, and we recommended the following modifications. Silt fence must be installed along the perimeter of the shoreline prior to any construction to protect the lake from erosion. The fill soil should be a granular material. Clay soil is not recommended for this type of application. The fill soil should be compacted in no greater than 6 inch lifts to a minimum specified density of 95% of the standard proctor density. The proposed fill and Miragrid is proposed to be installed up to the existing failure plane, as shown on the detail. There is nothing shown to anchor the Miragrid into the existing soil bank. We believe that future problems are likely at the same failure plane as before. We recommend using a system of duckbill anchors that are set into the existing soil bank and tied to a series of pipes or bars laid parallel to the shoreline. The Miragrid could then be attached or wrapped around these pipes to anchor it to the side slope. The proposed American Excelsior Biodegradable turf reinforcement is a temporary turf restoration and will not prevent future erosion unless an adequate vegetation and root base has been established. Maintenance of the 1:1 slopes will not be possible. We recommend seeding the slopes with a low maintenance vegetation such as Crown Vetch. The Crown Vetch is a spreading plant with a low profile and good root base. There are several permanent turf restoration products available such as Miramat which will further increase the stability of the surface. If there is a possibility of scouring of the embankment due to wave action along the shoreline, we recommend the placement of riprap with filter fabric to prevent erosion and undermining. 2335 West Highway 36 111 St. Paul, MN SS113 111 612-636-4600 L� Ms. Jeanne A.

Here is an amended drawing of my proposed shoreline restoration. In response to Shawn D. Gustafson's recommendations to you in a letter dated April 6, 1993 we have modified the plan to include the engineer's recommendations: A silt fence will be installed along the perimeter of the shoreline prior to any construction to protect the lake from erosion. The fill soil will be a granular material. A system of duckbill anchors will be set into the existing soil bank and tied to a series of pipes for the miragrid to be attached to anchor it to the side slope. In addition to the American Excelsior Turf reinforcement we will plant Crown Vetch to prevent future erosion. Riprap is already present along the property shoreline and since the proposed restoration is above the 929.4 elevation Ellen Klanderman of the Minnehaha Creek Watershed District said that type of permit isn't necessary.

PRODUCT PRESENTATION Mil Since 19a3, Mirafi has developed Miragrid products specifically to fulfill the require- ments of sal reinforcement technology. Cost effective reinforced sal structures can now be built, using high modulus, high strength, creep resistant polymer geogrids to meet stringent design criteria for performance over long service lives. Miragnd can be easily incorporated into your next project to increase useable land area, reduce site acquisition and%or development Machine Direction Strand Aperture J 1.3° I t.2" Node Cross Machine Direction Strand J costs, using reinforced steep slopes, retain- ing walls and aggregate rafts. Miragrid is a coated biaxial geogrid made of polyester yarns knitted into a stable geo- metric configuration. The yams are bundled into machine (roll) direction strands and cross machine (roll) direction strands, and spaced to provide uniform, large openings approximately one inch square These aper- tures allow soil to penetrate easily and form an efficient mechanical interlock with the reinforcing geogrid. The large percentage of soil particle to particle contact with Miragrid along with its flexible nature, make a very effective tensile reinforcement for both cohe- sionless and cohesive soils.

Multiple layers of Miragrid laid horizontally during slope construction inter- sect all potential failure planes due to the steepened slope. Thus providing tensile strength along the failure plane to increase its overall factor of safety against sliding, as shown below. Design procedures are avail- able to determine specific geogrid layout. MIRARID DIFFERENCE The Miragrid Difference, Slopes: Miragrid reinforced slopes generally reduce land acquisition costs, provide more useable area at the slope crest or toe, eliminate retaining walls or lower site development costs. Miragrid steepened slopes make a big cost saving difference by effectively solving problems, with. • Soft foundation soils • limited property boundaries • large earthwork volumes • Marginal fill soils 01 MIRAGRID Center for Failure Potential Plane —� Rotational Failure Plane MWemem an"tension Develop Along Plane ,� of Failure IF �Mw Reinforcement Soil Shearing ��� Tension Maintains Stability Resistance Maearftl PovMes bnseH reHarosrrrent m sat •rP=1 MNeeweleo® Slope Applications: Steep embankments using Miragrid are appropriate for the following project types: • Highway Embankments • Shooting Ranges • Earth Dams • Residential Developments • Mining/Mine Reclamation • CommerciallOffice Parks • Landfills • Dikes and/or Levees • Stream Channelization USES/APPLMr MNS Landslide Repairs Landslide repair is steep embankment con- struction for projects where conventional earthwork procedures were inadequate.

Miragrid's tensile reinforcement allows the aggregate to function as a much stiffer (rigid) layer, spreading applied loads over a larger area. A schematic section of the ap- plication is shown below.

Other sections related to this work: • Excavation • Embankment • Site Grading 1.0 Material Handitng & Storage Upon arrival at site, the geognif shhould be checked to ensure the proper material (strength) is received A product certification should be provided with each shipment stating the material conforms tothe product specifications published by the supplier. For ease of installation, the material should be stored above -10•F during winter months. Care should be taken to prevent mud, wet cement, epoxy, and like materials, which may permanently affix themselves to the gridwork, from coning in contact with the geogrid. The rolled material may be laid flat for storage and should be covered with a light colored tarpaulin to prevent long-term exposure to sunlight. 2.0 Material 3pecflica6ons The ggeeooggrid shall be composed of polyester yarn encapsulatedinaprotectivecosting Thepolyester yarns shall be pined by knitting or ultrasonic weld- ing at evenly spaced junctions to form a minimum aperture of 1.0 inch square. The geogrid should possess the following strength and tension creep characteristics. 3.0 Reinforcement Placement Prior to placing the reinforcement, the excavation shall be cleaned of all excess material and the foundation base proMrolled. The reinforcement shall be rolled out, cut to length, and laid at the proper elevation, location, and orientation as shim on the contract drawings. Orientation of the reinforcement is of extreme importance since geogrids vary in strength with roll direction. The roll direction of Miragrid should be laid in the direction of main reinforcement .ct The contractor shall be responsible for corre orientation. Reinforcement should be placed coincident with the compaction lift nearest the design elevation on the drawing. No partial or half -lift thickness are required. Geogrids can be placed directly on the existing fill surface. No special surface treatment, leveling or smoothing, is required. If a sheepsfoot roller is utilized, the imprints are an acceptable surface for reinforcement placement. Afterbeing rolled out, the reinforcing material should be tensioned by hand until it is taut, free of wrinkles, and lying flat. Overlaps as shown on the drawings should be maintained. No overlaps WIN be allowed in the direction of strength. Adjacent MH widths should Overlap a minimum of 4 inches. Mechanical connections between adjacent rolls should be made at this time, it required. Certain fill Properties, fill placement procedures, and/or weather conditions may require the reinforcement to be held in place by staples, pins, sand bags, or fill, as directed by the engineer MIRAGRID PHYSICAL PROPERTIES TENSILE Main TENSION CREEP Main STRENGTH & Reinforcing Cross- Reinforcing Cross.
