Respectfully Submitted, Murphy, Planning Depar Approved by the Apple Valley Planning Commission on Tom Melander, Chair city of Applen Valley ITEM: PLANNING COMMISSION MEETING DATE: SECTION: March 15, 2017 Land Use/Action Items PROJECT NAME: Johnson Deborah Variance PROJECT DESCRIPTION Jeff and Deborah Johnson, owners of 13500 Embry Way, want to add a 12' x 17' (204 sq. ft.) addition onto the rear of their home. The zoning code requires the rear of the house to be set back a minimum of 75' from the ordinary high water elevation of 902.4' of Pilot Pond (classified as Long Lake by the DNR). This request is to reduce the setback from 75' to 66' (9' variance). STAFF CONTACT: Kathy Bodmer, Planner DEPARTMENT/DIVISION: Community Development Department APPLICANT: Jeff and Deborah Johnson PROJECT NUMBER: PC17-05-V APPLICATION DATE: 60 DAYS: 120 DAYS: February 27, 2017 April 27, 2017 June 26, 2017 Proposed Action The Staff reviews variance applications based strictly upon the requirements of the state statutes and the City Code which require that the applicant establish that there are practical difficulties present in order for a variance to be granted, and that logical alternatives are not available. Staff therefore is unable to recommend approval i2DALEys because it does not meet the staffs strict interpretation of the zoning code and practical difficulties test. If the Planning Commission concurs with staffs finding, the following motion would be needed: • Recommend denial of the variance because the variance request fails to meet the City Code requirement for a practical difficulty. If, instead, the Planning Commission wishes to recommend approval of the variance, the Commission should state any practical difficulties and the following motion would be needed: • Recommend approval of a variance to construct a 12' x 17' four -season dining room addition subject to compliance with all City Codes and City development standards. Project Summary/Issues Background information: Jeff and Deborah Johnson, owners of 13500 Embry Way, request a variance to add a 12' x 17' addition onto the rear of their home to expand their existing dining room area. Pilot Pond is classified as part of Long Lake by the DNR and is therefore subject to the shoreland overlay zoning requirements; the rear yard of the lot falls within the SH setback. The minimum setback is 75' from the ordinary high water elevation of 902.4'. This request is to encroach into the SH setback by approximately nine feet (9') on the north side of the addition and five feet (5') on the south side of the addition. The Johnson home was built in 2013 on Lot 2 of Knottywoods 3rd Addition. The subject lot was created in 2006 by splitting an existing oversized single family parcel into two parcels. Variances were granted for the project to reduce the minimum lot area of Lot 1 abutting Pilot Pond from 20,000 sq. ft. to 18,742 sq. ft. Variances were also granted to allow a detached garage to be reconstructed on Lot 1 by reducing the required OHW setback from 75' to 50' and by reducing the Embry Way setback from 30' to 22'. The Knottywoods 3rd Addition development agreement specifically identified a building pad area on Lot 2 that would meet all the required setbacks. The development agreement states: 14. Any improvement constructed or built on Lot 2 shall be located within the building pad area as shown and noted on Exhibit `B' attached hereto. The requested variance would exceed the limits of the approved building pad area. It is staff's view that the approved building pad has sufficient room available to construct a sizable addition onto the home. However, such an addition may require internal remodeling. The owners state that internal remodeling would make the project infeasible. The proposed addition is convenient for the property owner, but staff finds that reasonable alternatives exist. The Johnsons state that the proposed addition is needed to provide a larger and more functional dining room area. A photo is provided that shows the existing dining area. The 12' x 17' addition is proposed to be constructed on posts in order to minimize impacts to the shoreland area. The Building Official states that any construction on posts will require additional engineering and design. The owners are aware of the rear yard setback constraints, but state that a larger dining room is needed for the home and that reasonable alternatives are not available. The impervious surface coverage of the lot is estimated to be 19% which would increase to 20.4% as a result of this addition. The impervious coverage is well below the maximum 30% allowed. The current footprint of the home and garage is 1,958 sq. ft. DNR Comments: A letter was sent to the DNR notifying them of the requested variance and providing an opportunity for comment. No comments have been received to date. Previously Granted Variances: Staff is conducting research into variances that have been granted to homeowners that abut one of the City's Recreational Development Waters lakes. In many cases, the Shoreland Overlay zoning district requirements were enacted after the homes were constructed, making it difficult for homeowners to make improvements to their homes. In the Johnson case, the building pad was identified at the time the lot was created. Variance Test: In order to grant a variance, the City considers the following factors to determine whether the applicant established that there are practical difficulties in complying with the provision(s) of this Chapter: 1. Special conditions apply to the structure or land in question that are particular to the property and do not apply generally to other land or structures in the district or vicinity in which the land is located; 2. The granting of the proposed variance will not be contrary to the intent of this chapter; 3. The special conditions or circumstances do not result from the actions of the owner/applicant; 4. The granting of the variance will not merely serve as a convenience to the applicant, but is necessary to alleviate practical difficulties in complying with the zoning provisions of this Code; and 5. The variance requested is the minimum variance necessary to alleviate the practical difficulty. Definition of "Practical difficulties": • The applicant proposes to use the property in a reasonable manner not permitted by the zoning provisions of the code; • The plight of the applicant is due to circumstances unique to the property not created by the applicant; and • The variance, if granted, will not alter the essential character of the locality. • Economic considerations alone do not constitute practical difficulties.

(0.36 acres) Topography: 10' drop in elevation from the basement floor level (918.16) to the rear property line (908.4) near Pilot Pond. Existing Vegetation Urban landscape. Other Significant Natural Features The parcel does not directly abut Pilot Pond, but is impacted by the "SH" overlay zoning district setback from the ordinary high water (OHW) level. The DNR classifies Pilot Pond as a part of Long Lake and therefore a Recreational Development Water and further subject to the "SH" requirements. The OHW of Pilot Pond is the 902.4' elevation.

The addition that would be built would be 12 feet deep by 17 feet wide (maximum). Only part of the addition would require a variance. A copy of the survey of the property with a sketch of the proposed addition is enclosed. Our home was built in 2013 by Wageman Homes on a narrow building pad. We are applying for a variance to create space for the dining room. Presently the dining room space is minimal and the expansion space for the dining room requires a variance. A picture of the current dining room space is also enclosed. The house is a walkout rambler and this addition would be on the upper level. The addition would be supported by posts and there would be no part of the addition structure that would go to ground level (except for the footings for the posts). The house is set back from Pilot Pond that is considered part of Long Lake (Long Lake is on the other side of Pilot Knob from the pond). The current location of the house from which the addition would be built is approximately 80 feet from the Pond on one end of the proposed variance and 82 feet from the Pond on the other end. We are requesting a variance of approximately 9 feet on one end and 5 feet on the other end. We may not end up using that much of the variance, depending on final design and pricing. Jerry Wageman of Wageman Homes is the contractor who would build the proposed dining room expansion. In summary: - The practical difficulty we face is the lack of dining room space - There is no alternative location, absent major and cost -prohibitive reconstruction - The percentage of impervious surface on our lot compared to the total lot size is much less than is allowed - currently the percentage of impervious surface is only about 18% - The percentage of impervious surface on our lot (even if we completed the addition) compared to the total lot size would still be much less than is allowed — the percentage of impervious surface would be about 19% - There would be no construction on ground level — only the post footings would be on surface level - The pond high water mark is 19 feet below the elevation of the house - The variance requested is only 9 feet at the maximum (and less on the other side of the build out) Thank you for your consideration of this matter.

Valley ITEM: PLANNING COMMISSION MEETING DATE: SECTION: f3 March 15, 2017 Land Use/Action Items PROJECT NAME: Valley Middle School and Southview Elementary Building Additions and Site Improvements PROJECT DESCRIPTION Site Plan Review/Building Permit Authorization for three building additions totaling 7,900 sq. ft., exterior building updates and reconfiguration of parking areas to enhance school security and improve internal traffic circulation. STAFF CONTACT: Kathy Bodmer, Planner DEPARTMENT/DIVISION: Community Development Department APPLICANT: Independent School District 196 PROJECT NUMBER: PC17-03-B APPLICATION DATE: 60 DAYS: 120 DAYS: February 1, 2017 April 1, 2017 May 31, 2017 Proposed Action 1. Recommend approval of the Site Plan Review/Building Permit Authorization for 7,900 sq. ft. building additions, parking lot modifications and site improvements subject to compliance with all City Codes and construction standards, subject to the following conditions: a. The site plan shall be revised to address the City Engineer's March 9, 2017, memo. b. The City Engineer shall review and approve the final grading, utility and stormwater plans prior to issuance of the building permit. c. A nursery bid list shall be submitted at the time of application of the building permit confirming that the value of the landscape plantings meets or exceeds 2-1/2% of the value of the construction activity. d. The landscape plan shall be revised to provide berming and landscaping of the north parking lot at Valley Middle School and the west parking lot at Southview, subject to final review and approval of the Natural Resources Coordinator. e. The Natural Resources Coordinator shall review and approve the final landscape plan prior to the issuance of the building permit. f. A Stormwater Infiltration Basin Installation and Maintenance Agreement shall be executed prior to issuance of the building permit. g. A staging and temporary parking plan shall be submitted prior to issuance of the natural resources management permit or building permit subject to review and approval by the City Engineer. 2. Recommend approval of a Variance waiving the requirement to plat the property in order to issue a building permit. Project Summary/Issues ISD 196 submitted plans for a construction and remodeling project of both Valley Middle School at 900 Garden View Drive and Southview Elementary School at 1025 Whitney Drive. The project includes building additions and internal remodeling to update and enhance security at the entrances. Parking lot modifications are proposed to better separate parent drop-off/pick-up traffic from bus traffic within the site and to minimize the backups that are occurring on Garden View Drive. Landscaping and stormwater retention will be added to the site as part of this project. Valley Middle School Project: A 5,100 sq. ft. addition is proposed for the main entrance on the east side of the building to update the exterior building design and improve school security. A 400 sq. ft. addition is also proposed at the north entrance to enhance security at the bus entrance location. Curb is proposed to be installed to separate the parking lot into two lots to separate parent traffic from the bus traffic. Buses are proposed to use the north entrance and parents will use the east entrance. Extensive internal remodeling is proposed in connection with the middle school project that will have no impact on the site plan or zoning requirements. Landscaping and berming will be needed of the north parking area to minimize impacts to adjacent properties. Southview Elementary Project: ISD proposes to relocate the front office and front entrance of the elementary school from the south side to the west side of the building. The entrance project will include a 2,400 sq. ft. addition with architectural elements that will help to easily identify the front of the building and provide additional security measures. A new 143 -stall parking lot and parent drop-off/pick-up area will be constructed on the west side of the building where two ball fields, hard surface and soft surface play areas currently exist. Parent traffic will be directed to the west lot while buses will continue to use the south lot. An existing driveway on the southeast corner of the site will be removed from Whitney Drive to provide additional bus queuing on the site. The hard surface and soft surface play areas would be relocated north of the new west parking lot. Impervious surface area is being added to the site as a result of the project which will require stormwater infiltration measures. A new infiltration basin is shown located between the new parent parking lot on the west and the running track. Landscaping will be required at 2.5% of the value of the construction of the building improvements. Additional berming and plantings are needed around the new parking lot and along Whitney Drive to help to mitigate impacts created by the new traffic and activity that will occur on the west side of the building. Street Impacts: The property abuts Garden View Drive to the east and Whitney Drive to the south. A traffic study was conducted that analyzed impacts to adjacent streets and intersections. Overall, the proposed improvements do not require modification to adjacent intersections. However, the study notes that back-ups and blocked lanes occur currently on Garden View Drive as parents and buses wait to enter the school site during peak times. The study does not address whether the issue of back-ups and blocked lanes is fully addressed as a result of the new parking lot configurations. Garden View Drive is a very busy major collector street in the City. The City Engineer is reviewing the proposed development to ensure that the project will address the congestion that occurs on Garden View Drive during peak times. Variance for Waiver of Platting: § 153.20 in the subdivision chapter of the City Code states: "No building permit shall be granted for the erection of any building or structure upon lands which are not platted in accordance with the requirements of [Chapter 153] ..." The Valley Middle School and Southview Elementary property was never platted, but building permits have been issued over the years. It is likely that the review of the building permit for the initial construction of the schools occurred at the State Building Official's office and that the subdivision requirement was not identified at that time. The construction will not occur near property lines, so staff is comfortable recommending a variance from this requirement. Building permits have been issued over the years without requiring platting. ISD 196 is concerned that requiring the preparation of a plat will delay the project timeline Budget Impact N/A Attachment(s) 1. Engineering Memo 2. Location Map 3. Zoning Map 4. Oblique Aerial 5.

A right of way permit will be required for all work within public easements or right of way. 16. A Natural Resource Management Permit (NRMP) will be required prior to any land disturbing activity commences. Site 1. The traffic study submitted by Wenck indicates a shift of 15-40 trips at the middle school to the Baldwin entrance by relocation of the teachers and buses. The plans need to show more clearly this updated change. Indicate on the plans where the new bus loading, parking and circulation is to occur in the north parking lot. 2. Internal routing patterns should be more clearly identified to determine if adequate vehicle storage is present to limit impacts to the adjacent roadways. The Wenck study also indicates the recommendation of the development of a Traffic Management Plan that will detail how drop-off, pick-up and parking activities will occur when fully operational. This should be provided with Traffic Impact Study. 3. Additional discussion in the Traffic Study is needed to identify the number of buses that will utilize each parking area to ensure adequate parking areas are provided. 4. Consider/evaluate modifications to the north and east VMS parking to maximize internal vehicle storage to limit impacts to the adjacent roadways. This may be achieved by extending the sidewalk and center parking lot median north from the eastern edge of building in lieu of angled sidewalk at NE corner of VMS as shown on site plans. Vehicles would enter the existing drive and turn right (north) and loop back south along the eastern side of building. This configuration would better utilize existing parking stalls to the north and create additional 300' of internal stacking length within the site for pick-up and drop-off. Additional signage to direct staff and pick-up and drop-off parking is recommended to be shown at the main VMS entrance to better direct traffic flow into the site. This would also better circulate traffic between the east and north lots for event parking and staff usage. 5. Remove the existing sidewalk connection shown from Whitney Drive to the existing entrance in the center of the bus drive along the south side of Southview. 6. Pavement section for median cut shall match existing Whitney Drive and be indicated on the plans. 7. Provide Auto tum drawing indicating vehicle movements to parking areas and internal circulation for both buses and vehicles. 8. Pedestrian curb ramps in accordance with City of Apple Valley standards are required at sidewalk crossings of entrances. 9. The east parking lot 2 should have yellow painted curb lines as this entrance and parking lot will still function as the primary emergency vehicle response access to the school. Additional striping and signage is recommended for emergency vehicle use. Grading, Drainage and Erosion Control 1. Final Grading Plans shall be reviewed and approved by City Engineer. 2. Final Stormwater Management Plan shall be reviewed and approved by City Engineer. 3. Provide the overall site composite Curve Number (CN) along with the impervious % on the area tabulation. 4. The NWL, 100 -year HWL and EOF should be indicated on plan sheets for storm water pond and infiltration basins. Hydraulic calculations shall be approved by the City Engineer. 5. The City of Apple Valley is required to find additional treatment options prior to discharging to Keller Lake as part of MS4 permit. 6. Runoff rate control will be required to reduce peak discharge from site as existing 66" storm sewer in Whitney drive has no additional drainage capacity. 7. Provide landscaped berms outside ROW and drainage and utility easements at the following locations for screening: a. Along Whitney Avenue from the proposed new drive entrance to Garden View. b. Along the north side of proposed soft lay 1 and hard surface play. Additional trees behind the proposed infiltration area and soft play 1 may be more appropriate due to drainage concerns with a berm. c. Along Baldwin Avenue adjacent to the existing access drive from the north parking lot 8. Drainage Areas P05, PO3BLDG, PO3A, PO3B, PO3C and PO2C are not drainage to proposed infiltration basin and continue to directly flow to existing 66" storm sewer in Whitney Avenue. 9. PO2A (3.1 acres) drains to proposed infiltration basin. The total site is 26.674 acres. Drainage areas PO3A and PO3B should be provided with Volume/Water Quality control (infiltration) in the open area between bus drive at Southview Elementary downstream of proposed CB -11 (sheet C1.51). The rerouting of CB 9 and CB 10 to CB 11 is recommended. 10. 2% minimum drainage should be provided for all turfed areas. 11. Perimeter protection is indicated on the proposed plan. 12. Street sweeping shall be provided should tracking occur during construction. 13. Rock construction entrance is indicated on the proposed plan. Additional entrance may be necessary during site and utility work as part of Building Addition 2 and proposed bus drive on the south side of Southview Elementary. 14. Inlet protection, silt fence and other erosion control features shall be maintained throughout the project. 15. Additional inlet protection will be required along Whitney Drive and Garden along the proposed trucking route. Sanitary Sewer and Water Main 1. Final locations and sizes of sanitary sewer and water main shall be reviewed with the final construction plans and approved by City Engineer. 2. Limits of removals should be shown for the connection to existing 9" VCP Sanitary Sewer along the east side of Garden View. 3. Clarify the need for multiple sanitary sewer services from Valley Middle School addition. Services not in use should be removed back to the main. Storm Sewer 1. Final locations and sizes of Storm Sewer shall be reviewed with the final construction plans and approved by City Engineer. 2. Provide storm sewer calculations for stormwater requirements. (Rational method including Hydraulic grade lines). 3. Storm sewer within right of way and public drainage and utility easement for purposes of connection to public infrastructure shall be reinforced concrete pipe and meet all City standards. 4. Provide a dewatering plan for the construction of manhole over existing 66" line in Whitney Drive. 5. Storm Sewer Manhole in ROW shall be in accordance with City Standards. Include City of Apple Valley Standard Detail Plate No. STO-3 16. 12" RCP connecting to 66" storm sewer in Whitney at MH 102 should outlet above the HGL to prevent surcharging and backups. The rerouting of CB 11 to the west and connect to existing 18" storm sewer is recommended in lieu of connecting to trunk storm in Whitney Drive. 17. Provide outlet structure to proposed infiltration basin. Landcape and Natural Resources 6. Keep infiltration area protected from vehicle traffic and stockpiling to prevent further compaction. It is unclear from the notes if adequate soil borings were completed prior to design to determine soil conditions and infiltration capacity in the infiltration basin. Provide soil borings in proposed infiltration areas. 7. Given the nature of a ballfield, it will be required to de -compact the soils in work areas in addition to the addition of top soil. 8. Clarify the emergency overflow for the infiltration basin is not onto the public sidewalk. 9. The ribbon curb from the new west parking area is not sufficiently angled for water to enter the infiltration basin. There could be some bypass. 10. Raingarden design and construction standards, plans, and details are incomplete for the project at this time. The City would recommend following the guidelines of the Dakota County LID Standards (http://www.dakotaswcd.org/pdfs/Dakota%2OLID%20Standards%2oRevised%2002-09- 12.pdf) for construction and design as well as the Minnesota Stormwater Manual. a. Dakota County Soil and Water Conservation District may be available to suggest alternative stormwater practices for the site. 11. Raingardens directly adjacent to parking lot need to provide buffers and/or pretreatment to prevent snow piles from winter maintenance within the basins. Snow storage must not occur in raingardens. Signage is required. 12. Plans should specify shredded hardwood mulch for the infiltration basin. 13. The infiltration basin planting template may be complex for maintenance in the future. Designs in clusters or rows of native grasses or shrubs may be easier to maintain. Also, all shrubs would reduce pedestrian traffic through the basin. a. How will prevent pedestrian traffic be prevented in the basin through establishment, not just during construction? Pedestrian traffic has implications for compaction and erosion if great enough. With the adjacent track and ballfields there may be more potential for extra pedestrian traffic. 14. The sediment control log detail is inadequate. Depending on the material the log is made of, it needs to be trenched/keyed in slightly. This should be reflected in the standard detail provided. 15. Sheet L1.11 shows four ash trees as existing but were cut down several years ago on the eastern side of Southview Elementary. Please update tree inventory with what currently exists on site. a. Clearly indicate which trees are proposed for removal with an "X". 16. In the Valley Middle Park parcel a majority of the ash trees along Baldwin Drive and Garden View Drive have been preventatively treated for Emerald ash borer by the City. The City would prefer any berms or grade changes required for screening do not negatively impact these ash trees. 17. Of the —46 existing trees on the school property, 11 are ash trees and approximately 12 are maples. Consider preventative treatments to save the mature healthy ash trees. (The City has discounted prices available to preserve significant ash trees.) a. An additional consideration could be phasing of the removal and replacement of selected trees with a wide diversity of new trees along Garden View Drive. There will be no mature trees on the school property along Garden View Drive when Emerald ash borer infests and kills the row of ash. 18. The replanting plan indicates 12 additional maples. Given the quantity of maples currently on site, please diversify the species and consider limiting maples as the next invasive insect species favors maples. The hackberry, oak, and elm are great choices for this area. 19. The applicant needs to ensure that the basin drains within 2 days when completed. If the basin does not drain within the required timeline, the applicant will have to make corrections until it does. 20. Care needs to be taken that the plants do not get drowned out before reaching maturity. 21. Vegetation establishment does not end with installation of plantings and mulch within the infiltration basin. The property owner should plan on at least a year of watering and weeding following the year of installation for a quality garden effect. 22. Restoration/Landscape plan should indicate required buffers and appropriate seed mixtures for infiltration area, aquatic bench and upland areas associated with any stormwater basins. Signage is required to be placed along perimeter of proposed basin. The buffer should provide separation from manicured lawn area. 23. Landscape plan should clearly indicate drainage and utility easements and property line. 24. No major tree plantings shall be located over any underground utilities. Clusters of trees shall be used near or around these areas instead of planting in a row. The Drainage and Utility Easement will require clearance around the underground utilities, or the expectation that trees may have to be removed for access when needed. 25. Trees and shrubs planted around the infiltration areas should be above the designated HWL. 26. Plant schedule and labeling is not consistent with plans: 27. Plant schedule missing definitions for UD. 28. Greenspire Linden is listed as TC on the Schedule but GL on the plan. 29. Tree cluster "3 UD" at South end of West Parking shows 9. 30. Tree cluster "3 UD" at North end of West Parking shows 4. 31. Tree cluster directly East of this "9 TL" shows 7. 32. Tree cluster directly East of this "5 SR" shows 7. 33. Trees listed on East side of Garden View as part of existing trees — this is not school property. ConsultingGroup, Inc. To: E NGINEERS P LANNERS D ESIGNERS Brandon Anderson, PE, City Engineer City of Apple Valley From: Matthew Pacyna, PE, Senior Associate Tom Sachi, PE, Senior Engineer Date: March 3, 2017 Subject: Draft Review Summary SRF No. 10460.00 Review of Traffic Study for Southview Elementary and Valley Middle Schools Apple Valley, MN Introduction As requested, SRF has completed a review of the Traffic Study for Southview Elementag and Vall6y Middle Schools in Apple Vally, MN document, dated February 22, 2017 completed by Wenck Associates. The proposed development is generally bounded by Garden View Drive to the east, Whitney Drive to the south, and Baldwin Drive to the north. Review of the travel pattern changes, operations analysis, access, and queuing identified the following questions and comments for consideration. Review Summary Based on our review, the following items were identified: 1. Travel Pattern Changes — The total entering/exiting vehicles were compared for the existing conditions versus post construction conditions. Under post construction conditions, 10 additional entering and exiting trips were included compared to existing conditions. This occurred in each scenario except for entering volume in the 6:45 to 7:45 a.m. peak hour, but is not expected to significantly change the study results. 2. School Information and Buses — Traffic counts were taken during the arrival and departure periods of the schools. However, the exact times for the schools are not listed in the report nor were the exact number of buses identified for either school, which are necessary to review any potential parking, access, and circulation modifications. 3. Traffic Operations — The operations analysis focused only on the Garden View Drive and Whitney Drive intersection, excluding any of the existing school access points. A Synchro analysis was completed using the Highway Capacity Manual and peak hour factor adjustments to account for school conditions. The method of the traffic operations analysis appears to have been completed accurately for the study intersection. However with school studies, it is important to understand internal (pick-up/drop-off) and access operations, particularly from a queuing perspective. The study does not address internal queuing (under existing or future conditions) and the relative impact or interaction to adjacent roadway operations. Access, circulation, and queuing should be reviewed under existing and proposed conditions to determine if adequate internal storage is provided to ensure minimal impacts to the adjacent roadways.
