Madden <br />Twenty-Second Floor <br />410 Seventeenth street <br />Denver, Colorado 80202 <br /> <br />Re: Bruchez Farms Property Adjacent to BIg Dry Creek <br /> <br />Dear Mr. Loewl: <br /> <br />We are pleased to present thIs revIsed report detailing our InvestigatIons concern- <br />Ing the defInItIon of the floodplain in the vIcInity of the Bruchez Farms property on <br />BIg Dry Creek just downstream of Standley Lake. Our origInal report was completed <br />on September 10, 1987 and was subsequently reviewed by the Urban DraInage and <br />Flood Control DIstrIct and the city of WestmInster. <br /> <br />The 1986 FHAD report by Greiner EngIneerIng placed almost all of the Bruchez Farms <br />property withIn the floodplain of Big Dry Creek, Our report represents a more <br />detailed, in-depth study of this reach of Big Dry Creek. Changes were made to the <br />existing HEC-1 computer models by IncorporatIng an Improved inlet wIth the existing <br />Colorado 8. Southern Railroad culvert, by utilizIng the existIng storage upstream of <br />the railroad, and by IncorporatIng the changes requested by the reviewing agencies. <br /> <br />The results of our Investigations IndIcate that the depth of water just upstream of <br />the railroad during the 100-year flood event Is several feet lower than that shown in <br />the 1986 study. ThIs lower water surface removes most of the Bruchez property <br />from the floodplaIn of BIg Dry Creek. <br /> <br />Very truly yours, <br /> <br />WRIGHT WATER ENGINEERS, INC. <br /> <br />By ~/~~ <br /> <br />RonaldL.
