Marshan Lakeview /Funkhouser Estates Page 2 January 21, 2005 . City of Lino Lakes, Minnesota 2) The proposed site development results in grading (disturbing of property) of over 1.0 acre. The development shall therefore be subject to the requirements of NPDES (National Pollution Discharge Elimination System) as most recently adopted by the Minnesota Pollution Control Agency (MPCA) and the City of Lino Lakes. The applicant shall therefore be responsible for retaining and administering a Stormwater Pollution Prevention Plan (SWPPP) in accordance with State of Minnesota law. Grading 1) As noted in the previous review, a drainage concern was expressed with regards to Lots 2 and 3 of Block 1. Although the grading plan does indicate an acceptable routing of runoff, special care must be taken during actual construction and final grading to assure that drainage between the two units is attained. 2) As mentioned in the previous review, the applicant shall ascertain the adequacy of the existing soils for the roadway, utility, and house constructions. No soil or geotechnical report is provided. Although the Resource Inventory Survey identifies fine sands for much of the site, any imported material for the site shall be subject to the approval of the City Engineer. In addition, floor elevations for the proposed housing units must meet the requirements of the City of Lino Lakes as follows: The lowest building opening must be a minimum of 1 -foot higher than detention basin emergency overflow elevation. Basement floor elevations must be at least 4 -feet above the normal water elevation and 2 -feet above the design flood level. The applicant shall be responsible for attaining any permits as required for de- watering. Utilities 1) It is proposed to connect to existing sanitary sewer and water, recently constructed on Marshan Lane. The applicant shall be aware that the sewer is relatively shallow and that low floor elevations and sewer plumbing for the proposed housing units must be designed accordingly. A sewer forcemain service has therefore been proposed for Lot 1. 2) The applicant shall be responsible for the coordination of private utilities (electric, gas, cable, etc. as needed. 3) Individual sanitary sewer and water services for all three units are provided. However, as stated in the previous review, the 6 -inch diameter water main extension shall be revised to 8 -inch diameter in accordance with City standards. The 8X6 reducer proposed at the connection to the existing watermain should be replaced by an 8 -inch gate valve. Insulation must be provided for all sanitary sewer and water (mains and /or services) that will have less than 7.5 feet of cover over the top of the pipe. A detail for the type and installation of insulation must be provided.
