MN 55323 Re: Stonebay File No. 139-03-000 Plat No. 02-2789 Dear Mike: We have reviewed the final construction plans for the proposed Stonebay development. The site is located in the northwest quadrant of the intersection of Willow Drive and T.H. 12. The proposal provides for a mix of residential housing and future commercial development. We have the following comments in regards to engineering matters. Sanitary Sewer: • All sanitary sewer services should be «-fect deep. Any services less than 8-fect deep shall be adequately insulated. No services shall be less than 5-fcct deep. The plans show sewer service inverts on Cascade Lane and Sandstone Circle with less than 3-fect of cover. These should be revised to prevent fi^eezing and to avoid contlicts with private utilities. • All sanit.iry and water services should be stubbed to the backside of the 1 0-foot drainage and utility casement as shoMu on the plans. Water Main: • The applicant has requested using PVC water main as an alternative to DIP. This is acceptable provided the pipe used meets all specifications that the DIP meets. If PVC water main is used it must be installed uith tracer wire and kll tracer wire shall be tested prior to water main acceptance. • The City wishes to extend the proposed water main on Kelley Parkway southerly within the east 10-foot drainage and utility easement over Outlot D. The applicant should provide a 1 2-inch stub and valve to a point 10-fccl south of the southerly Kelley Parkway right-of-way for the City’s funirc extension. • Water mam high points should be eliminated or hydrants added at the following locations: 1 . On Boulder Drive 40-fcct east of San. MH-25. 2. Near San. MH-9. 3. Near San. MH-6. 4. Between San. MH-14 and San. MH-13. 5. At San. MH-16. 6. Bc^veen San. MH-1 5 and San. MH-2. • Stainless steel bolu shall be used on all fittings, joint restraint, valves and hydrants. • A 1 2-mch w s :cr main should be stubbed easterly across Willow Drive to the easterly right-of-way at the Kelley Parkway intersection for future extension to the well house. • 1 he proposed water main between Kelley Parkway and T.H. 1 2 should be 1 2-inch. Storm Server: A drainage area map, storm sewer and ponding calculations should be submitted for our review. The plans should identify the overland emergency overflow (EOF) routes for all wetlands and ponding areas. Spot elevations should be shown along all overland EOF routes including any routes north of the site (Willow View). All storm sewers within the street sections shall have a minimum of 3-feet of cover between the finished street 2335 West Highway 36 • St. Paul. MN 55113 • 651-636-4600 • Fax: 651-636-1311
