comprises a significant portion of the proposal. The process will include identification of drainage basins without an outlet, perennial ponding areas that require remedial • action to protect structures and streets. The process will also include creation of a storm water model for the City that can be manipulated by the staff in the future. This will provide the ability to assess the potential impact of new development on downstream properties. Currently we receive models for each site that show how the storm sewer on site will function; however, we lack the capability of dete the cumulative effect of multiple projects on a drainage way. The City has been part of the FEMA Flood Insurance Program since 1979. There were several areas in that study where the flood elevation was not determined. The WRMP will provide data for updating the Flood Insurance Maps for Ramsey for the areas where the elevation was not established and reviewing areas where significant development has occurred. This plan will be an update of the 1980 Comprehensive Storm Drainage Plan. There were amendments in 1987, 1997 and 2002. The 1997 and 2002 amendments only covered the southeast quadrant of the city where updated topographic information was available. The 1980 plan was prepared using USGS 10 foot contours, which were the best available data at the time. This update will utilize the 2003 Aerial maps with 2 foot contours commissioned by the city. Data for areas developed after the aerial maps were created will use the approved plans on file at the city. Staff has requested that the WRMP be a working document, organized so that the • recommendations and action items are easily identifiable and can be implemented in a systematic approach. The storm sewer model requested will assist in this process. The request for proposal (RFP) was approved by the Public Works Committee in January 2007 and ratified by the City Council in February. Requests were sent out in March to seven consultants identified by staff as having experience in preparing studies of this nature. Staff met with each consultant after they had a chance to review the REP and answer their specific questions. Proposals were received on April 12 and then reviewed and ranked. Each consultant prepared a quality proposal and evaluation to determine the finalists was a lengthy process. The evaluation criteria were spelled out in the RFP and are summarized below: 1. Project Understanding: The firm's understanding of the project and concerns of the City as presented in the proposal. 2. Project Approach: Clarity, innovation, organization and overall responsiveness to the RFP. 3. Project Personnel: The assignment of qualified and experienced staff who have proven their ability to work together as a team. 4. Firm References: Firm's past performance on City projects, inquiries with previous clients and other references. 5. Firm Experience: Qualifications and expertise of the firm and key project • personnel in performing services required for this project as demonstrated by the quality of the firm's previous and current projects. —116—
