CASE# J 7 <br />APPROVE CHANGE ORDER TO GLEN REHBEIN COMPANIES FOR <br />SUNWOOD DRIVE NW STORM SEWER ADDITIONS <br />By: Leonard Linton, Civil Engineer <br />Background: <br />This project was authorized for construction of MSA Streets in Ramsey Town Center. <br />The work includes extension of trunk Storm sewer through the Ramsey Town Center <br />Project. The storm sewer installed in this project connects to developer installed utilities <br />north and south of Sunwood Drive. <br />The developer requested revision of the trunk storm sewer system to accommodate the <br />needs of the purchaser of the parcel located in the southwest quadrant of Sunwood Drive <br />and Zeolite Street. A large regional pond was located on this site in the Final Plat <br />documents. The purchaser requested that the pond size be reduced to provide more <br />developable space on this site. The RTC design group submitted a revised design to staff <br />for review which incorporated redirecting some storm water from the south west pond to <br />other regional ponds onsite. The changes do not affect the rate of discharge from the site <br />to the Mississippi River. The Lower Rum River Water Management Organization has <br />reviewed the proposed changes and found they were acceptable. <br />The changes to the regional storm sewer system require increasing the size of some of the <br />pipes installed under Sunwood Drive and relocation of some storm sewer structures. <br />These modifications are in the project area covered by this contract, however they do not <br />improve the fiinction of the MSA street so the developer was requested to cover the cost. <br />The RTC LLC has submitted a letter indicating they will reimburse the city for the cost of <br />the storm sewer changes in this change order. <br />Recommendation: <br />Staff recommends approval of Change Order #4 to Project 03-29. <br />Action: <br />Motion to approve Change Order #4 to Improvement Project #03-29 in the amount of <br />$79,083.30 and adopt attached Resolution #04-11-XXX accepting Change Order #4 to <br />improvement project #03-29, MSA streets in Ramsey Town Center. <br />Reviewed By: <br />Public Works Director <br />Assistant Public Works Director <br />CC: 11/09/04 <br />
