Flood depth for are is 9.0-ft, per FIRM map #06077C0430F. Site is approximately 18-feet below flood level (Elev. = -9.0-ft). Describe the current depth of the ground water and depth to potable water: Current ground surface to water surface depth = approximately 18.4-feet Describe any existing drainage courses or eroded areas on or near the project site (e.g. rivers,creeks, swales or drainage ditches): Drainage ditch or swale abuts on North, East and West side of property. Land, Land Use and Biota Describe the site's topography(e.g. land forms, slopes, etc.): Site is relatively flat and slopes from the South to the North to drainage swale. There is approximately a 3-ft change in elevation from the South to the North side of the property (Slope = less than 1.0%). Describe agricultural land that will be lost as a result of the project(type of crops,acres, quality of soil, etc.): The proposed location of the blast-resistant modular buildings is already graded and base rocked. Therefore, no agricultural land will be lost. Describe any wildlife habitat on-site and species that are or may be present: A preliminary screening of the site has been conducted and no endangered wildlife appear to be present that could be affected by the project. Prior to releasing the project into construction, a detailed environmental review of the site will be conducted in order to address environmental sensitivities located at the site. Describe any vegetation on-site by type and extent: The proposed location of the blast-resistant modular buildings is already graded and base rocked. Therefore, no additional vegetation will be removed. Air Quality Describe air pollutants that may result from the project(e.g.construction related dust,vehicle trips per day, fire places, incinerators, etc.): Flatbed trucks will deliver a total of (7) - 12'x40' blast resistant modular (BRM) to site. Assumed that this would equate to total of 7 truck trips. F:IDEVSVC1Planning Application FormsTlood Variance.doc.(Revised 5-11-09) Page 4 of 7
