The <br />site is located at 1365 Tonkawa Drive (C.R.135) north of North Shore Drive (C.R.51) in the <br />southeast quarter of Section 8. We have the following comments in regards to engineering matters. <br />1. Access: Outlet A as shown on the plat does not provide adequate width for a public or private <br />street as outlined in the City Ordinance. A minimum right-of-way of 50 feet should be provided <br />for cither public or private streets. Private streets .serving three to seven units must be paved 24 <br />feet wide. Public streets should be paved to 28 feet in width. We recommend that the shared <br />driveway to .serve Lots 2 and 3 be reconsidered. A cul-de-sac would provide more room for <br />emergency vehicle turning movements than the proposed shared driveway / hammer handle <br />design. Outlot A should be extended to the westerly property lire of Lot 1 if the City is <br />considering a future easterly extension of Birch Lane. The construction of Birch Lane to <br />Tonkawa Road could eliminate a substandard shared driveway and reduce the number of <br />accesses onto C.R. 51. The fire department should review the plans and provide comments. <br />Plans should be submitted to Hennepin County for their review. <br />2. Utilities: Sanitary sewer exists along the southerly lot line of the property. Sewer stubs have <br />been provided to the 3 proposed lots. The well location for the existing house should be shown <br />on the final plans. Utility construction plans should be submitted for review. <br />3. Grading: A grading and erosion control plan for the entire site should be submitted for review. <br />Erosion control measures should be in place prior to any grading, particularly along the <br />lakeshore. Additional erosion control will be needed during construction of the houses. <br />4. Drainage: The draft version of the City ’s Comprehensive Storm Water Management Plan <br />(SWMP) shows that the site lies within the North Arm drainage district. The entire site <br />drains northerly to the lake. A water quality pond should be located on the site to provide for <br />stonn water treatment. A drainage area map w ith pre and post development calculations should <br />be submitted for review. <br />2335 West Highway 36 • St. Paul, MN 55113 ■ 612*636*4600 ■ Fax: 612*636*1311
