With final plat applicant shall show storm pipe sizes for all pipes crossing Rosemary Way. • Water Supply There is existing 8-inch diameter ductile iron pipe (DIP)watermain located in the northwest corner of the intersection of Main Street(CSAH 14) and 24th Avenue. The City of Lino Lakes Comprehensive Plan designates trunk watermain extending along a future road extension west of the site. Staff has evaluated the need for the trunk line to go through this site to meet anticipated fire flow needs. The applicant is proposing an 8-inch diameter DIP watermain to serve the development. The watermain will extend north along 24th Avenue and then to the west along the proposed Rosemary Way and dead end at the end of the proposed road. The applicant currently shows 8"watermain stubs to each lot to provide service to the buildings. Comments: 1. Watermain along Rosemary Way and 24th Avenue shall be 12" in diameter. 2. Applicant is responsible for verifying water suppression needs for the buildings. Potential looping within the sites may be necessary. 3. All watermain stubs shall end with a temporary hydrant and gate valve. Do not include gate valves on the stub legs of the watermain. Permanent gate valves will be installed when the watermain is extended in the future. 4. The Deputy Director of Public Safety- Fire division will review the hydrant layout. • Sanitary Sewer There is an existing 27-inch diameter poly-vinyl chloride (PVC) Metropolitan Council interceptor line located in the northwest corner of the intersection of Main Street (CSAH 14) and 24th Avenue. The invert of the stub is approximately 899.93 and is to be field verified. The City of Lino Lakes Comprehensive Plan designates a trunk sanitary sewer line to go through this site. The applicant is proposing to extend the 27-inch line to the north and then serve the development with 8-inch diameter PVC sanitary sewer. Two 8-inch diameter sanitary stubs are proposed to serve the proposed buildings. Comments: 1. Applicant to install 27-inch diameter sewer along Rosemary Way. The City will cover the costs of oversizing the sanitary sewer. 2. Applicant to add City Standard Detail SAN-4 for drop manholes. 3. Manholes shall not be located within the pipeline easement. 4. Applicant shall verify if 8" sanitary stubs or 6" sanitary stubs are being installed to the Lot 1 and Lot 2. Belland Farms plans show 8", but AECP plans show connecting to a 6" stub. 5. Staff has concerns with the current location of the sanitary sewer along 24th Avenue based on its depth. The sanitary is too close to the building to be able to safely make future repairs. Staff recommends switching the location of the watermain and sanitary sewer along 24th Avenue. Belland Farms&Associated Eye Care Partners Engineering Review
