MEMO TO: Kathy Glanzer, Scott Tangen FROM: Paul Heuer RE: Petrina Park Terrace Twinhome Development FILE: BRA File No. 37233 DATE: May 16, 1997 nBonestroo 0 Rosene Anderlik & Associates Engineers E. Architects We have received and reviewed the preliminary plat (dated 4- 29 -97), drainage and erosion control plan (4- 17 -97), utility plan (4- 17 -97), and the grading and drainage plan (4- 17 -97) for the above mentioned project and offer the following comments. SANITARY SEWER & WATER MAIN A 12 inch diameter trunk sanitary sewer and a 16 inch diameter trunk water main run through the Allen extension between Centerville and Desoto. Although the City has no Comprehensive Sewer Plan or Comprehensive Water Plan to check capacities with, it is assumed that capacities will be no problem if the area was designed for the higher flows that an industrial area typically generates. We urge the owner to utilize as many of the existing sanitary sewer services as possible along the Allen extension. These existing services (and manholes) should be shown and labeled on the utility plan. Sanitary sewer services are shown connecting directly to manholes. The City's policy is to have in -line wye connections to avoid blockages in manholes. When more detailed plans are developed, gate or butterfly valves should be shown that allow the cul -de -sac water systems to be isolated. A stretch of about 900 feet of property along the west side of Centerville Road south of the Allen extension currently has no City water main. We understand that at least one resident has approached the City with a request for installing this water main as part of the Pitrina Park Terrace development. We recommend that the affected residents be surveyed to determine the level of interest in serving them with City water main. If the response is positive, then two viable options are: 1) have this work included in the Pitrina Park Terrace development, or 2) attach this work to the existing Arcade Street contract. All necessary bid items already exist in the Arcade Street contract at very competitive prices. If this option were chosen, a decision should be made by the end of June to allow the Contractor time to plan his work. Page 13
