DATE <br />CITY OF RAMSEY LAND USE APPLICATION <br />TECHNICAL REVIEW FILE <br />MAY 24, PROJECT ADDRESS SOUTH END OF BOWERS <br />2017 <br />PROJECT. TITLE PEARSON PLACE <br />EscRow # 115701 <br />DEPARTMENT: Engineering <br />Name: Leonard Linton <br />TECHNICAL Phone: 763 433-9834 <br />Email: llinton@ci.ramsey.mn.us <br />REVIEWER: <br />DRIVE <br />We offer the following comments regarding the Sketch Plan submittal for Pearson Place. The <br />submittal consists of 2 sheets prepared by Otto Associates dated May 4, 2017. <br />We offer the following comments on these sheets: <br />Sheet 1: <br />1. No comments. <br />Sheet 2: <br />1. Soil borings will be needed for each of the primary and alternate septic areas. The septic <br />areas should be laid out to allow access to the back yards without driving over the primary <br />or alternate areas. <br />2. Soil borings will be needed for the house pad areas and proposed infiltration areas to <br />document groundwater levels. <br />3. Proposed infiltration areas will need to be in drainage and utility easements. <br />4. This project is adjacent to a plat that was approved in 1949, prior to any stormwater <br />regulations. Runoff from the project must be attenuated prior to reaching the existing <br />street. This project will need to meet the Lower Rum River Watershed Management <br />Organization requirements for volume control, water quality and rate control. The volume <br />reduction requirement is infiltration of the first 1 inch of runoff from new impervious <br />surfaces. Rated control is limiting developed runoff rates to the existing rates for the 2, 10 <br />and 100 year storms. Water quality standards are met by providing wet detention equal to <br />the 2.5 inch storm and removing 60% total phosphorus and 90% total suspended solids <br />from the discharge. <br />
