Wl <br />Dear Mike: <br />We have reviewed the preliminary plat for the proposed four lot VanMoorlehem subdivision. The <br />site is located at 4490 Watertown Road near the intersection of County Road 6, McCulley Road and <br />Watertown Road in Section 31. We have the following comments in regards to engineering matters. <br />1. Access: The existing intersection of County Road 6 / Watertown Road and McCulley Road / 6'^ <br />Avenue is controlled by stop signs in the easterly direction of County Road 6 and in the westerly <br />direction of Wcuerlowf. Road. McCulley Road / 6*^ Avenue is a through street with a high point <br />h.'cared appi o/ imately 150 feet southwest of this intersection. The configuration and control of the <br />Miterseciion may change based on this summer’s proposed intersection improvements by Hennepin <br />County. Lot 1, Block 2 fronts both McCulley Road and County Road 6. Lots 1 and 2, Block 3 abut <br />McCulley Road, Watertown Road and Tumham Road. Steep slopes exist on McCulley Road along <br />all three lots. The existing access to Lot 1, Block 1 appears acceptable. Access to Lot 1, Block 2 <br />could be off ol County Road 6 or McCulley Road provided the access is located at least 600 feet <br />from the intersection. If the access is off of County Road 6, the location should be reviewed by <br />Hennepin County. Access to Lots 1 and 2, Block 3 should be from Turnham Road. The plat may <br />reed to be revised to provide access to Lot 2 from Tumliam Road. <br />». Existing and proposed well locations should be shown on the plan set. Utility <br />con^truclion clans 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 measure.s should be in place prior to any grading. Additional erosion control will <br />be needed during construction of the homes. <br />4. Drainage: The draft version of the City’s Comprehensive Storm Water Management Plan <br />(SWMP) shows that the site lies within the drainage districts PC-29 and PC-37. Lot 1, Block 1 and <br />Lot 1, Block 2 drain northerly to an existing ponding area identified as PC-P99 in the SWMP. Lots <br />I and 2. Block 3 drain southwesterly to pond PC-P40. Water quality and quantity issues should be <br />•:idd:essed as part of tl:e design in accordance with City standards. The post development runoff <br />leaving the site ihould be maintained at prcdevelopment levels. Ponds PC-P99 and PC-P40 have <br />■ itni. been classihed as moderately susceptible wetlands. These wetlands will require that <br />2335 West Highway 36 ■ St. Paul, MN 55113 ■ 612-636-4600 ■ Fax: 612-636-1311
