PUBLIC AWARENESS AND PARTICIPATION PROGRAM <br /> <br />In order to develop a successful project implementation plan, the said plan must receive the support <br />of the community, public officials and the City Council. WRC recognizes the importance of public <br />awareness and participation throughout the planning and adoption process. <br /> <br />Based on our past experience in this area of soliciting public input and securing approvals from the <br />Community, different Commissions, Boards and the City Council, WRC proposes the following: <br /> <br />a. Upon selection of WRC for this project, WRC will recommend to the City/CWCB to consider <br />setting up a Committee to provide input during the preparation of this work. <br /> <br />b. WRC will recommend that the committee membership be comprised ofleaders from the business <br />community in the City (representing such groups as home builders association, realtors, <br />Chamber of Commerce, commercial and industrial sector), selected environmental groups, <br />outdoor recreation groups, League of Women Voters, homeowners associations, representatives <br />of applicable boards and commissions, applicable county state and federal government agencies, <br />and others as identified by the City and CW CB. <br /> <br />c. Once the Committee identified in Item 2 is formed, the City, CWCB and WRC Staff will meet <br />with the Committee periodically, present information, and solicit input. <br /> <br />5. HYDROLOGIC ANALYSES <br /> <br />It is our understanding that previous hydrologic analyses work will be used for this smdy. The <br />City/CWCB will provide WRC with the design flows and hydrographs at critical design points. Our <br />effort in this task will be minimal, and will be directed at reviewing information and assuring <br />ourselves of its reasonable accuracy. For those systemwide tasks which require combined <br />hydrographs from two or more different sources, WRC will review with the City and CWCB any <br />modelling inconsistencies (i.e. time base differences) to obtain a consensus on methodology and <br />results. <br /> <br />6. HYDRAULIC ANALYSIS <br /> <br />The hydraulic analysis for this project could consist of a number different types of analyses. These <br />analyses can be categorized as follows: <br /> <br />a. Floodplain Hydraulics: This task is essentially the verification, computer input and model <br />correlating of existing HEC-2 analysis. <br /> <br />I) Obtain from the City, CWCB, or Federal Emergency Management Agency any available <br />HEC-2 analysis input and output files currently used to regulate the floodplain / floodway. <br /> <br />2) If necessary, convert said data into P.C. Files and provide said files on diskette to the Client <br />with accompanying descriptions and hard copy printouts. <br /> <br />Having previously made HEC-2 conversions, WRC is aware that exact duplication of water <br />surface and energy grade line elevations is not achievable due to the use of different analysis <br />algorithms in the current P.C. version of HEC-2 as compared to the original versions. This <br />knowledge allows us to quickly identify real errors in data conversion versus spending <br />extensive time examining apparent errors which are really ouly caused by changes in the <br />analysis algorithms. <br /> <br />I <br /> <br />CITY OF STERLING/CWCB 4 WRC ENGINEERING, INC. <br />
