Storm Drainage System Improvements <br /> Dear Steve, <br /> This letter proposal represents our proposed Scope of Services and cost estimate to provide a <br /> hydrologic/hydraulic analysis and preliminary design of drainage system improvements for the <br /> Frederick Ct. storm drainage system. The Scope o~~,Services describes our approach to provide a <br /> hydraulic analysis of the storm drainage system from Monroe St. to its outfall into Amazon Creek. <br /> Based on the results of the hydraulic analysis, we will complete a preliminary design of drainage <br /> system improvements. This letter proposal contains the following information: <br /> • Our understanding of the existing flooding problems <br /> • scope of services for the hydraulic analysis and preliminary design <br /> • City services required <br /> • project lead person and technical support staff <br /> • estimate of hours and costs by task to complete the scope of work <br /> • schedule of work <br /> EXISTING CONDITIONS <br /> The Frederick Ct. stormwater drainage system, located in the Amazon Creek Basin, originates at <br /> the City limits along Sundial and W. 40th. The drainage system upstream of Frederick Ct. is a <br /> combination of pipes and open waterways. Near W. 34th and Olive, the drainage system is piped <br /> ' until its outfall into Amazon Creek. Piped segments adjacent to Delwood Drive and between W. <br /> 37th and Frederick Ct. appear to constrict flows from upstream development. In addition, several <br /> of the open waterway segments do not have adequate access for maintenance. In response to these <br /> ' problems, we have developed the following scope of work and cost estimate: <br /> SCOPE OF SERVICES ` <br /> Task 1-Frederick Ct. Storm Drainage System Analysis <br /> Objective: Develop ahydrologic/hydraulic model of the Frederick Ct. drainage system. Use the <br /> model to complete a hydraulic analysis of the drainage system. Identify pipe segments or open <br /> waterways that do not have adequate capacity. <br /> <br />
