Variance 4646 Dakota Street SE Prior Lake, MN 55372 PLANNING COMMISSION AGENDA REPORT MEETING DATE: JULY 17, 2017 AGENDA #: 4B PREPARED BY: PRESENTED BY: CASEY McCABE, COMMUNITY DEVELOPMENT DIRECTOR CASEY McCABE AGENDA ITEM: PUBLIC HEARING AND CONSIDER APPROVAL OF A RESOLUTIION AP- PROVING VARIANCES FROM THE MINIMUM STRUCTURE LAKE SETBACK, MAXIMUM IMPERVIOUS SURFACE COVERAGE, MINIMUM LOT AREA AND MINIMUM ACCESS ELEVATION FOR A PROPERTY IN THE R-1 SD (LOW DENSITY RESIDENTIAL SHORELAND) ZONING DISTRICT DISCUSSION: Introduction Copper Creek Development is requesting variances from the minimum structure setback from the Ordinary High Water (OHW) elevation; the maximum impervi- ous surface requirement; the minimum lot area for development of a nonconform- ing lot of record; and minimum elevation for vehicular access to allow the con- struction of a single-family home on a property located at 14468 Shady Beach Trail NE. The property is currently vacant and is located along the northern shore of Lower Prior Lake, south of Shady Beach Trail, on Lot 4, Shady Beach No. 2 (PID 250460040). The following variances are requested: ➢ A 30.16-foot variance from the required minimum 50-foot structure setback from the Ordinary High Water (OHW) elevation of Prior Lake using the aver- age lake setbacks of adjacent properties (Subsection 1104.308 (2)) ➢ A 3.8% variance from the 30% maximum impervious surface requirement for a residential property in the Shoreland District (Subsections 1104.306 & 1104.902 (1)) ➢ A 58-square foot variance from the minimum 7,500 square foot lot area re- quired for development of a nonconforming lot of record (Subsection 1104.902 (1)) ➢ A 2.2-foot variance from the required minimum vehicular access elevation of 906.9 feet (Subsection 1105.402 (4)) History The property is zoned R-1 (Low Density Residential), and is guided R-LD (Urban Low Density) on the 2030 Comprehensive Plan Land Use Map. The property is currently vacant.

The low density residential lot is 7,442 square feet in area and the vehicular ac- cess point is at a 905.7’ elevation. The applicant is proposing an impervious surface coverage of 33.8% and a structure setback of 19.84 feet from the OHW. Lake Setback: The applicant is proposing the structure would be located a min- imum 19.84 feet from the 904’ OHW elevation in the rear yard. The average structure setback distance of properties to the immediate east and west of the subject property, as identified on the survey, is 13.45 feet. Impervious Surface Coverage: The current City Ordinance requires a maxi- mum of 30% impervious surface per residential property in the Shoreland District. The applicant is proposing an impervious surface area of 33.8% of the total lot area above the OHW. Lot Area: The lot area of the subject property is 7,442 square feet. While the Shoreland Ordinance does require a lot to be a minimum of 7,500 square feet for development of the property into a single-family dwelling, this property has been valued and assessed as a buildable lot for single-family dwelling purposes for many years. Minimum Vehicular Access Elevation: Residences are required by City Code to have vehicular access at or above an elevation not more than 2 feet below the regulatory flood protection elevation. The regulatory flood protection elevation of Prior Lake is 909.9’ which requires an access point above 907.9’. The site has an access point of 905.7’, requiring a 2.2’ variance. While not requiring a variance, the garage floor (not the dwelling portion of the house) is proposed to be constructed with a finished garage floor elevation of 908.10, which is located below the regulatory flood protection elevation of 909.9’. Floodproofing techniques are proposed which would allow water to flow into and out of the garage in the event of a flood. These techniques are required per FEMA and state flood plain regulations for structures constructed below the reg- ulatory floodplain elevation. The garage cannot be located at a higher elevation without creating a steep driveway situation greater than permitted by City Ordi- nance (10% max.) or lengthening the driveway thereby reducing the lake setback of the home even further than proposed. Conclusion City staff believes the variances requested are warranted due to the lot con- straints unique to the property and practical difficulties as stated in the findings below. City staff does recommend the following conditions be included with the variance approval: ➢ The variance resolution shall be recorded at Scott County. ➢ An acknowledged City Assent Form shall be submitted to the Community De- velopment Department prior to the issuance of a building permit. ➢ Due to its proposed elevation below the regulatory floodplain of Prior Lake, the attached accessory garage shall be floodproofed according to FP-3 or FP-4 floodproofing classification in the State Building Code. 3 ISSUES: This project includes requests for variances. Section 1108.400 states that the Board of Adjustment may grant a variance from the strict application of the provi- sions of the Zoning Ordinance, provided that: (1) There are practical difficulties in complying with the strict terms of the Ordinance. “Practical difficulties,” as used in connection with the granting of a Variance, means the property owner proposes to use the property in a reasonable manner not permitted by the Zoning Ordinance. Economic considerations alone do not constitute practical difficulties. There are practical difficulties in complying with the strict terms of the Or- dinance. This residential property has some unique characteristics includ- ing the nonconforming lot area and low lot elevation. (2) The granting of the Variances are in harmony with the general purposes and intent of the City Subdivision and Zoning Ordinances and the Comprehensive Plan. The granting of the variances appears to be in harmony with the general purposes of the Ordinance and Comprehensive Plan. A purpose of the Zoning Ordinance to “Promote the most appropriate and orderly develop- ment of the residential, business, industrial, public land, and public areas”. Furthermore, the Shoreland Ordinance (Section 1104) policy states, “it is in the best interests of the public health, safety, and welfare to provide for the wise development of shoreland of public waters.” (3) The practical difficulty is due to circumstances unique to the property not resulting from actions of the owners of the property and is not a mere convenience to the property owner and applicant. The small lot area of 7,442 square feet and low lot elevation are circum- stances unique to this property are do not result from actions of the prop- erty owner. (4) The granting of the variances will not alter the essential character of the neighborhood or be detrimental to the health and safety of the public welfare. The granting of the variances will not alter the essential character of the Shady Beach Trail neighborhood. There are many riparian properties in this area with similar lot conditions. (5) The granting of the Variances will not result in allowing any use of the property that is not permitted in the zoning district where the subject property is located. The requested variances would allow construction of a residential dwelling which is an allowed use within the R-1 (Low Density Residential) Zoning District. 4 ALTERNATIVES: 1. Motion and a second to approve a resolution approving the variances re- quested for 14468 Shady Beach Trail NE with the listed conditions, or ap- prove any variance the Planning Commission deems appropriate. 2. Motion and a second to deny the variance requests because the Planning Commission finds a lack of demonstrated practical difficulties under the zon- ing code criteria. 3. Motion and a second to table or continue discussion of the item for specific purpose as directed by the Planning Commission. RECOMMENDED MOTIONS: Alternative #1. ATTACHMENTS: 1. Location Map 2.
