TPC FILE: 236.02 — 21.04 BACKGROUND Olivia Gavic, representing Creative Homes Inc. has made an application for a Planned Unit Development Amendment to allow for changes to a boulder rock retaining wall for Lot 8, Palmer Station located at 5573 Oak Cove North. The Planned Unit Development Amendment is required to vary from the changes to the original grading plans and locations of the retaining wall. The City Council approved the request for the rezoning, Planned Unit Development, and Preliminary and Final Plat for the thirteen-lot subdivision of the Palmer property at their July 22, 2014 meeting. On July 28, 2020, the City Council approved a Planned Unit Development Amendment for reduction in the front yard setback from 30 feet to 20 feet for Lots 7, 8 and 9 of Palmer Station or 5606, 5573, and 5607 Oak Cove North, respectively. The current proposal is to place the new dwelling 20.5 feet from the property line for Lot 8 and to make changes to the retaining wall. The property is zoned R-1 Single Family Residential District. The review is based upon the following submittals: Exhibit 1: Certificate of Survey for Lot 8 Exhibit 2: Elevation Diagram of Boulder Wall Exhibit 3: Site Pictures Exhibit 4: Report of the City Engineer PROJECT DESCRIPTION Ms. Gavic has indicated that the reason for the request is to allow the expansion of the existing retaining wall to allow construction of a three-car garage and to keep proper drainage through the lot. The house will be pulled forward to 20 feet from the property line which will keep it aligned with the adjacent existing house. The site plan indicates a portion of the retaining wall to be removed and the line marked in red on the survey shows the proposed retaining wall location. The elevation diagram shows the wall to be constructed from fieldstone boulders with a wrought iron fence at the top of grade. The highest part of the wall is 12 feet tapering to one foot. The fence is needed for any part of the wall over a four-foot elevation. ISSUES ANALYSIS Comprehensive Plan. The Comprehensive Plan 2018 designates this area as Low Density Residential. The Palmer Station development is in conformance with the Comprehensive Plan. Zoning. The property is currently zoned R-1 Single Family Residential District. The R- 1 District requires a front yard setback of 30 feet, side yard setbacks of 10 feet and rear yard setback of 30 feet. The Planned Unit Development Amendment approved in July 2020 reduced the front yard setback by 10 feet to 20 feet. Exhibit 1 shows the proposed building footprint at the 20.5-foot setback. The change to the retaining wall was considered enough of a variation to the grading plan that it required a Planned Unit Development. The retaining wall and grading shall be subject to approval of the City Engineer. Planned Unit Development Amendment Review. The Planning Commission and City Council should review the criteria for a Conditional Use Permit in considering the Planned Unit Development: The conditional use permit criteria, found in Section 401.03.A.7 of the Zoning Ordinance, are found as follows: 1. Relationship to the specific policies and provisions of the municipal comprehensive plan. 2. The conformity with present and future land uses in the area. 3. The environmental issues and geographic area involved. 4. Whether the use will tend to or actually depreciate the area in which it is proposed. 5. The impact on character of the surrounding area. 6. The demonstrated need for such use. 7. Traffic generation by the use in relation to capabilities of streets serving the property. 8. The impact upon existing public services and facilities including parks, schools, streets, and utilities, and the City's service capacity. 9. The proposed use's conformity with all performance standards contained herein (i.e., parking, loading, noise, etc.). 2 Comment: The Planning Commission should comment if any of these criteria will be at odds with the Planned Unit Development Amendment proposed for the site. The changes to the retaining wall and grading will not negatively impact any of the above criteria. City Staff does not see any issues with the request. Grading and Drainage. A grading plan has been provided as part of the submittals. The City Engineer shall review and approve all of the grading and drainage plans including the boulder rock retaining wall. The City Engineer has provided a letter that is found as Exhibit 4 and includes a condition that the City shall be notified when the final grading of the lot is complete, prior to placement of sod, so that the grades and drainage can be confirmed. Easements. No existing easements will be impacted, nor new easements are required with this request. CONCLUSION / RECOMMENDATION Upon review of the request for a Planned Unit Development Amendment to allow for changes to a boulder rock retaining wall and grading for Lot 8, Palmer Station located at 5573 Oak Cove North, City Staff recommends the application with the following conditions: 1 . The final grading and drainage and plan for the boulder rock retaining wall for Lot 8 shall be subject to approval of the City Engineer. 2. The boulder rock wall shall be constructed as per the certificate of survey dated March 4, 2021 and the wall elevation dated March 24, 2021 including the addition of the wrought iron fence as indicated. 3. The City shall be notified when the final grading of the lot is complete, prior to placement of sod, so that the grades and drainage can be confirmed, subject to approval of the City Engineer. 4. Any other conditions of the Planning Commission, City Council and City Staff. pc: Julie Hultman 3 N Revisions: BENCHMARK Certificate of Survey for: 1 ,,ComminM_3/4/71 -� 70P OF SPINE 2 v Commmle-�/�I/21 ,-1 1 t1 E1.95&22 / ^ r t 1�R 1 f' Ea1e H CREATIVE HOMES, INC. - r ,� r•r�v L- / 1 ra,or Faye = A I/ �`� /, #959.+ House Address: L- i-, r. 4,u - j (ynder a �� Ed. �� i / °`"°"> /j� 5573 Oak Cove North,Oak Park Heights,MN Retaining Wolf-N 5B• 1 ,/ /1� A to be removed I a *4. 11 1 /J'° 9sB.2 f a 1 ti�/ n House Model: \`-I .._ �� �� X40 a s . .4ljb► � W center of aft.wide basin Victoria Bearings shown are assumed arom 1 -s ��0 ,, q `..,/ .„ ,--maderg lan acc.ve Per GRAPHIC SCALE $8 `--`C a S� 'J/ r b 9y,1!' / r/ grading Dlan Existing s n_ _ a trw Fence `,♦J Ege `-T2.a�!•, 5 2, -/ :09.9,s t'/i \ ,,- .._9N‘4 \ /� Total Lot Area. 121,iJ2 sq.ft. 0 15 / aw 53., c=23'zzp_t,..,-.1,45....„,..„..-• '�- yB6• `Y �( / Total Sod Area to Back of Curb 15,286 q.ft.

Oak Park Heights, MN 55082 Reference: Palmer Station: Certificate of Survey Review, Lot 8 (5573 Oak Cove North) Dear Eric, We have reviewed the certificate of survey submitted for Lot 8, Palmer Station, dated 3/31/2021 (attached). The survey shows proposed retaining walls that have been reconfigured compared to the originally approved grading plan. The proposed revised concept for Lot 8 is consistent with the intent for the lot drainage indicated on the approved grading plan and the as-built site grading. As a condition of the permit for this lot, include the requirement that the City be notified when the final grading of the lot is completed (before the sod is placed)so that the grades and drainage can be confirmed before the sod is placed. If you have any questions or require further information, please do not hesitate to contact me. Regards, St«ii«c Consulting Services Inc. Lee M.
