its MSA system. Staff would propose adding Andre Street/164th Lane, a 1.87 mile street segment to the City's MSA system. This segment meets the requirement of beginning and terminating on the existing system and this roadway functions as a local neighborhood collector. The street was constructed in 1985, is over 20 years old, and is eligible to collect full needs. Mr. Jankowski indicated it would still be necessary to revoke the mileage on portions of 142nd Avenue and Traprock Street to be able to accommodate this mileage addition. The City will be within 0.28 miles of the maximum allowed with these modifications. Mr. Jankowski stated. staff recommends adding Andrie Street from Alpine Drive to 164th Lane and 164th Lane from Andrie Street to Jarvis Street to the City's MSA system. He noted an alternative MSA designation could be a portion of Waco Street through Rivers Bend. Councilmember Dehen requested clarification that this MSA designation would not affect the neighborhood as far as widening the street. Public Works Director Olson replied that would be a separate action for Council to act on. It would be decided atthatfime what level to upgrade the street to. . City Engineer Jankowski explained there are certain standards that have to be met for upgrading an MSA street, but there is a lot of latitude. Motion by Councilmember Dehen, seconded by Councilmember Olson, to recommend to City Council that Andrie Street from Alpine Drive to 164thLane, ~d 164th Lane from Andrie Street to Jarvis Street be added to the City's MSA system. Councilmember Olson commented this is the best street to designate; it is on the western edge of the City where it is really needed. Motion carried. Voting Yes: ChairpersonElvig, Councilmembers Dehen and Olson. Voting No: None. Case #7: Receive Request from Green Valley Greenhouse for Drainage Improvements City Engineer Jankowski stated included in the Committee's packet is a letter dated March 16, 2007 from Mr. John Rowe of Green Valley Greenhouse requesting the City to address a drainage issue which exists along the portion of the property fronting along CR 63, Green Valley Road. Included in the Committee's packet are two photos illustrating the nature of the problem on March 12,2007 during a recent snow melt event. During the March snow melt event the Public Works Department provided equipment to pump the water several hundred feet to the south to a point where the water could flow by gravity to the Trott Brook. The Public Works Department has responded twice to this problem in the last five years as a similar situation occurred several years ago. Mr. Jankowski stated a drainage plan had been prepared in 2006 by MFRA Associates, an engineering consulting firm hired by the greenhouse. The plan has been submitted to the City as documentation for a credit toward the storm water utility fee. This drainage plan appears to correct the problem situation. Mr. Rowe has explained that the concern expressed in his letter centered on the cost of the improvements and.. whether the proposed drainage system would be handling runoff coming from areas outside of his property.
