1992-03-17 Prelim Plat Review MEYER-ROHLIN, INC. ENGINEERS-LAND SURVEYORS 1111 Hwy. 25 N., Buffalo, Minn.55313 Phone 612-682-1781 March 17, 1992 Albertville Planning Commission c/o Linda Houghton, Clerk PO Box 131 Albertville, MN 55301 Re: Psyks 5th and 6th Additions Preliminary Plat Planning Commission Members: Mr. Doug Psyk, the applicant, has submitted an application for preliminary plat approval of a 19-1ot, single-family subdivision to be named Psyke's Fifth Addition and an 18-1ot, single-family subdivision to be named Psyk's Sixth Addition. It is our understanding that preliminary plat approval is requested for both the 5th and 6th Additions; however, only the 5th Addition can be developed at this time. A release from MPCA for additional sewer service will be required for the 6th Addition. Both the 5th and 6th are submitted at this time to assure compatibility of street grades, drainage, etc. for the two. 1. The property in question is zoned R-3, single and two-family district. The following chart indicates the zoning requirements and the proposed plats' conformance to the requirements: Requirement Required Proposed Met Min. lot size 12,500 12,500 to yes 20,200 Lot width at building line Interior 90 90 to 115 yes co rn er 100 100 to 118 yes Setbacks Front 35 35 yes Side 10 10 yes Co rner 20 20 yes Rear 25 min. 25 yes Thore P. Meyer, Professional Engineer Robert Rohlin, Licensed Land Surveyor Albertville Planning Commission Page 2 2. The proposed preliminary plat indicates the required fi ve- (5) foot drainage and utility easement along all lot lines. The plat also provides a la-foot easement along the street lines. Additional drainage easements are shown in areas subject to storm water drainage and storage. 3. The walkway, or access to the wetland area, shall be over a 14-foot dedicated park land between Lot 1, Block 4 and Lot 1, Block 5. This dedicated walkway coincides with the sanitary sewer trunk easement. 4. The drainage system for the 5th Addition utilizes the existing lowlands as detention ponds with outlets into the wetland areas. storm sewer will be provided for the street and rear lot line drainage system with eventual outlet into the wetland areas. As the general terrain is relatively flat with very little relief from high land to the wetlands, cross sections have been provided with the drawings to assure each house pad will receive proper drainage. The grading of the streets and sites wi 11 be done under a city contract and supervision, to be assessed back to the developer, to assure proper drainage of all critical areas. Final construction plans may vary slightly from the preliminary plans. The drainage for the 6th Addition will be dependent upon a drainage easement over the adjacent property. The natural drainage direction from the 6th Addition is to the northeast into the large 7-acre wetland area located on the Marx property. A storm sewer easement or temporary drainage way easement will be needed on this adjacent property if the 6th Addition is to be developed. 5. The utilities, water and under a city contract and compatibility with the expansion areas. sani tary sewer, shall be installed supervision to assure coordination and existing system and planned future 6. street grades are at or greater than the minimum street grades (0.5%) required by the ordinance. street construction will be done under city contract and supervision and will be according to the city standard for residential streets (36--foot width, concrete curb and gutter, 12" gravel base and 3" bituminous surfac ing) . 7. This subdivision is subject to the City's Parkland Dedication requirements. As no parkland is shown on the preliminary plat, a per-lot deposit for parkland will be required. This should be clarified with the Park Board. Albertville Planning Commission Page 3 Based upon the above review, our office would recommend approval of the proposed preliminary plat subdivision that would create 19 single-family lots and 18 future single-family contingent upon the following: 1) Clarification of the parkland dedication requirement, 2) The developer enters into any required developer agreements, 3) Enter into Chapter 429 Improvement Agreements with the City for all platting, site and street grading, utility and street construction.
