City ofC~nlerviJ~ Cel/lervi/k DOWIIlOWn /l2deWlnpmflnl Prc1ecl Dec.!mber 19. 2006 PGge 1 Idenlifying the areas or concern will be accomplished through discussion with local government staff and regulatory agencies, and. if appropriate.. other affected parties. Soliciting input and addressing environmental concerns from all parties early on in the EA W process is invaluable in minimizing project delays. Should previously unrecognized environmental issues become evident during this process. (he scope or the environmental analysis (see Task 5) can be modified to address the concerns. . Supporting studies that appear at this time to be needed include analyses of traffic impacts. air quality and noise impacts. and wetland impacts (see Tasks 1-4 below). A stonnwater analysis wilJ also be needed but will be completed under a separate scope of work. It is assumed that the results of tlle stonnwatcr analysis will be available in time for use in preparation of the EA W. For the purposes of this proposal, it is asswned that other studies or field surveys (such as cultural resources/archaeological surveys. etc.) will not be necessary to complete the EA W, or that they will be completed under a separate scope of work. If additional studies or field surveys become warranted, we will contact you immediately and discuss bow you wish to proceed. Task 2: Traffic Analysis The traffic study included in the CSAH 14 study docs not appear to include sufficient future growth to cover the proposed land uses in the City's redevelopment area. Therefore. a rraffic study relative specifically to the proposed redevelopment project will be completed in order to detennine the traffIC impacts that could be expected to result from the project. We propose the following activities to complete the traffic portion of this proposed developmenl's EA W: · Collect necessary background infonnation on the project, including traffic counts at six (6) intersections during the a.m. and p.Ol. peak hours. · Prepare peak hour traffic tOTecasts for the study intersections for the years 2010 and 2030. Prepare average daily traffic forecasts on CSAH 14 and CSAH 21 for the years 2010 and 2030. . Analyze the traffic impacts oftbe proposed development for the years 20 10 and 2030. The analyses would include the peak hour operations at the study intersections and the daily volumes on the study roadways. . Prepare a draft report discussing our process, results, and recommendations for the traffic operations associated with the proposed development. Our collection of background data includes confinning that less intense development was used in the CSAH 14 EA W to ensure this traffic study is needed. Three meetings with the City. developers, andlor the County are also expected to discuss our processes and results, including a kick-off meeting to discuss initial assumptions and study direction. Task J: Wetland DeterminationJDelineadoD Since we are outside of the growing season (April- October), a wetland detennination will be performed to identifY wetlands located within the project ara. We anticipate investigating at least three areas based on aerial photo, National Wetlands Inventory, and hydric soils map review. We wiD provide preliminary wetland boundaries based on the freld investigation. In the spring (during the growing season). a wetland delineation will be performed in accordance with U.S. Army Corps of Engineers standard jurisdictional wetland delineation protocol to identify wetland areas and detennine potential impact or avoidance issues. A wetland delineation report will be prepared and submitted to the Rice Creek Watershed District for approval as the LocaJ Government Unit (LOU) responsible fortbe adminislration of the Wetland Conservation Act (WCA). 3J
