The project involves the redevelopment ot' <br />30 parcels (126 acres) ofland with light industrial, office/sho\\Toom. and commercial busiJh..'sses. <br />The following comments are offered for consideration and response by the city in its decisiolll)Il <br />the need for an Environmental Impact Statement. <br /> <br />Item 9 Land Use <br /> <br />The EA W makes note of soil and ground water investigation and cleanup activities conducted in <br />conjunction with development plans. This discussion also serves to emphasize the need to advise <br />developers or property owner of their potential liabilities for cleaning up any significant levels of <br />contaminants which may be encountered. Questions regarding the cleanup of petroleum releases <br />under the Voluntary Investigation and Cleanup (VIC) program may be directed to <br />Michael Kanner, Chief, Tanks and Emergency Response Section. Hazardous Waste Division <br />(297-8564). Questions on the Superfund VIe program may be directed to Richard Sandberg. <br />Chief, Site Response Section, Ground Water and Solid Waste Division (296-7290). <br /> <br />Item 18 Surface Water Runoff <br /> <br />Projected changes in runoff volumes for ten-year and 100-year events are given. We request that <br />infonnation for the corresponding analysis be provided for a two-year event as well. This is <br />based on the significant erosion potential of stonns in this range and the potential for their <br />attenuation through runoff controls compared to more catastrophic events. <br /> <br />Item 19 Wastewater <br /> <br />Part 19a requests a description of the quantities of all potential wastewater that could be <br />generated including domestic sewage. How is the wastewater flow expected to change compared <br />to previous uses of this site? Also, please summarize infonnation available which demonstrates <br />that the projected flows from the project area plus all adjacent contributing areas wil! not exceed <br />the design of the receiving sewers. <br /> <br />520 L,,'a:iet!e Rc 1'J S' P,,> ;"1'~ 5::'5::.~':;''':612' 29~d::30rJ "/8'':0 6:2: 222.5332 <br /> <br />q-::.~.,")...2. ;J.. ~:-:-:; - 'r-" =..~ ----:-"::. :~::.~: - - -:~-:-~.
