The site is located west of Stubbs Bay Road Noth and south of TH 12 in the north half of Section 32. We have the following comments in regards to engineering matters. 1. Access: The proposed access location off from Stubbs Bay Road appears accq}table. The proposed roadway will need to have a minimum paved width of 28 feet to meet City standards for a public or private street serving 7 or more units. The proposed cul-de-sac is approximately 1100 feet long where City standard allow for a maximum cul-de-sac length of 1000 feet. The plans should be reviewed for any conflicts with the future realignment of T.H. 12. The developer should be aware that the City will reconstruct Stubbs Bay Road this summer and eliminate the at grade railroad crossing and the existing access at T.H. IZ 'fhere is a need for a future east west roadway between Stubbs Bay Road and Orchard Park Road. It makes sense at this time to make provisions for a future westerly extension of the proposed roadway serving this property. City staff should research and further review possible alignments for a future westerly roadway extension prior to preliminary plat approval. It may make sense to dedicate 33 feet of right-of-way along some or all of the west boundary of the parcel. Thirty-three feet of right-of-way currently exists west of the west property boundary. Thirty-three feet of right-of-way also exists from the southwest comer of this parcel to Orchard Park Road. Final plans should include geotechnic.al recommendations and street design including horizontal and vertical curve information. 2. Grading: A grading and erosion control plan for the entire site should be submitted for review. It appears that driveway and street construction will require some wetland filling. Driveway locatiotu. should be shown and wetland impacts identified on the final plan set. Erosion control measures should be in place prior to any grading, particidarly along the wetlands. Additional erosion control will be needed during construction of the houses and septic systems. 3. Drainage: The draft version of the City ’s’ Comprehensive Storm Water Management Plan (SWMP) shows that the site lies within two major drainage districts. The northerly and southerly portions of the site flow to the west and lie within the Painters Creek drainage district. Final plans should include water quality provisions for storm water leaving the northerly and southerly portions of the site. The central portion of the site flows easterly and lies within the Lake Classen drainage district. The receiving water body for the Lake Classen portion of the site is a wetland identified as LC-C-32 in the SWMP. The wefiand is located E 2335 West Highway 36 ■ St. Paul, MN 55113 ■ 651-636-4600 ■ Fax: 651-636-1311
