Mr. Jim Studenski, P.E. City of Lino Lakes November 5, 2002 Page 2 3 Show proposed easements for drainage purposes. Show drainage and utility easements parallel and along the proposed property lines. 4. The proposed infiltration swale along the northerly development property line is shown with a 2% slope but computes to only a 1.6% slope between the rainwater garden and the west infiltration basin. Correct on plans and in stormwater calculations. 5. Correct and revise parking stall grades as water appears to be trapped in the northerly stall of six (6) stalls on the east of the site and south of access road from Lake Drive. 6. Recommend that when on -site or imported soils are used to fill low areas that they must be a minimum "SCS - Soil Group B" material. 7. All development site concrete curb and gutter is to be Mn/DOT B618. For the proposed "flat" areas, it is recommended that a pattern be established to maintain the back of the curb to the maximum extent possible. This will be a better guide to vehicle drivers and will protect the adjacent stormwater system from damage. The pattern should consist of a three (3) foot opening with one (1) foot tapers along areas designated for "flat" curb, as shown on the plans. 8. Provide to the City a copy of the Anoka County Highway Department permit (approval) for driveway access requirements prior to construction start-up. B. Watermain: This extension and service would require plans and specifications that follow City standards for utility construction in public rights -of -way. It would also require Anoka County, Lino Lakes, and Minnesota Department of Health permits. C. Sanitary Sewer. In general, the proposed sanitary sewer alignment from 4th Avenue to the Development site is acceptable with the following comments: 1. Provide the City with a permanent 20' wide easement that is parallel to the proposed sanitary line. Also, grading along the easement that provides future maintenance access. 2. A sanitary manhole will be needed at the junction of the N-S 8" sanitary pipe and the 6" sanitary service pipe to the building. Also, check with the City regarding the size and material of the service pipe to the building as well as clean-out or other manhole requirements.
