COUNCIL COMMUNICATION FORM Engineering & Infrastructure Memorandum NO. 2002-78 December 4, 2002 TO: Honorable Mayor Howley and City Council FROM: Steve Garman, City Manager Stephen Swanson, P.E., Director of Engineering & Infrastructure Matthew C. Newell, P.E., City Engineer�� SUBJECT: Drainage Area 18/Karen Drive Area Drainage Improvements, City Project 2002-36 SUMMARY RECOMMENDATION: An item on the agenda for the December 16, 2002, City Council Meeting is the authorization of an agreement for a preliminary drainage study with Phillip W. Cochran Consulting Engineer (PWC), for a fee not to exceed $13,900 for the Drainage Area 18 / Karen Drive Area Drainage Improvements. Staff recommends that the City Council approve the attached agreement. BACKGROUND: Drainage Area 18 is the area of the City, north of Pershing Road, that drains to Spring Creek. A map showing the proposed drainage study area is attached hereto. Three years ago the City completed a major drainage improvement to a portion of Drainage Area 18 south of Karen Drive along Greenridge Drive. At the time, it was staffs goal to begin addressing the known drainage problems in the area north of Karen Drive. Budget priorities and time constraints have not allowed this design study to proceed. With the proposed development of the Mound Middle School site, the drainage problems in this area take on a greater urgency. If City drainage policies are adhered to, it is likely that drainage will not increase from the site, however, area drainage will be impacted. For years, the proposed study area has been plagued by poorly defined drainage ways and ditches that have not efficiently conducted storm water runoff through the area. Many of the drainage ways are in back yard areas that are inaccessible to routine City maintenance.
