Ms.Katie Larsen 7/72021 Page 2 The existing parcel is within the Reshanau Resource Management Unit. The applicant is proposing approximately 23,614 square feet of new impervious surface for the proposed roadway, driveways, and building pads. If only considering the Block 1, Lots 1 &2 of Block 2, and Outlot A, this amount of impervious is above the 40% maximum impervious surface cover as stated in the City of Lino Lakes Zoning. The applicant will be required to work with the Rice Creek Watershed District and obtain a CAPROC if they move forward with development. A stormwater BMP is needed to meet City stormwater requirements because the site is over one (1) acre. The applicant is proposing to meet City stormwater requirements by constructing a stormwater pond on Outlot A. The design of the pond shall meet the requirements of Table 6 of the City's Stormwater Management ordinance. • Water Supply The existing property is identified as a Stage 1A Planned Service Area in the 2040 Comprehensive Plan. There is existing 8-inch diameter ductile iron pipe (DIP)water main along Oak Hollow Lane north of the site and 8-inch diameter DIP water main east of the site along Ware Road. A stub extends to the property line of 6149 Ware Road. The existing single family home is connected to the City's water system along Ware Road. It is feasible to extend the 8-inch diameter water main to service the proposed lots. The proposed townhomes will be required to connect to the City's water system. • Sanitary Sewer The existing property is identified as a Stage 1A Planned Service Area in the 2040 Comprehensive Plan and straddles the 1A and 1C sanitary sub-districts. There is existing 8-inch diameter polyvinyl chloride (PVC) sanitary sewer, 4-inch diameter PVC force main, and an 18-inch diameter MCES interceptor along Ware Road. There is existing 8-inch diameter polyvinyl chloride (PVC) sanitary sewer along Oak Hollow Lane north of the site that flows north to 8-inch diameter sewer along Ravens Court. A sewer stub extends to the north property line of 6149 Ware Road with an invert of 894.33 according to the record plans for Raven's Hollow development. The existing house is connected to the sanitary sewer on Ware Road. Assuming the sanitary sewer is extended for the entire length of the development at minimum grade, the sanitary depth would range from 894.33 to approximately 895.00. It is possible to extend the 8-inch diameter sanitary sewer to serve the townhomes in Huntson Addition. However, staff recommends that this be the last extension of the sanitary sewer in this area due to concerns with grades and shallow pipe depth. The proposed townhomes will be required to connect to the City's sanitary sewer system. • Transportation The site is located at 6149 Ware Road and abuts the southern portion of Oak Hollow Lane. Oak Hollow Lane was extended to the south with the intent of future development access during the construction of Raven's Hollow. Ware Road has a 66-ft wide right-of-way in this area, but requires 80-ft wide right-of-way as a minor collector road. Oak Hollow Lane has a 60-ft wide right-of-way. Oak Hollow Lane is a local city street and has capacity to handle the Huntson Addition Concept Plan Engineering Review
