<br />additional drainage facilities to divert flow away from paved areas. <br />'!he system can be designed to direct surface water into the existing <br />area drainage system. Actual drainage patterns will remain <br />essentially unchanged. <br /> <br />RunOff will increase slightly due to the introduction of additional <br />paved areas. These increases, however, appear to be insignificant <br />relative to the downstream system design. New drainage facilities at <br />the aiJ:port will be designed in accordance with FAA Advisory Circular <br />150/5320-5, Airport Drainage, thus minimizing the amount of nmoff and <br />~Jimil'\ating significant land erosion and increases in turbidity. <br /> <br />~t..-.d.. of n-.~-Qt14t.1a1 Act, Sect:ia1 4 (f) <br /> <br />No publicly-owned land from a public park, recreation area, or <br />wildlife and waterfowl refuge of national, state or local significance <br />will be utilized or affected by either of the proposed airport sites. <br />'1berefore, there will be 00 significant adverse impacts relating to <br />Depart:Dtent of 'lDnsportation Act, Sectim 4(f). <br /> <br />~ Arcbit&~I'm!II1, ~.a. r"!~lo]:ical cmd CI1ltural Reswxoes <br /> <br />The proposed airport development program is confined primarily to <br />existing, disturbed land.

Additionally, since the airport development <br />program is confined to existing disturbed areas wi thin the airport <br />property it is highly unlikely that rare or endangered species of <br />flora or fauna will be significantly impacted by the proposed program. <br />Furthermore, the program will not affect water resources, Le., <br />wetlands, groundwater, or impoundment, diversion, deepening, <br />CXI1trolling, modi.fyi.ng, polluting, dredging, or filling of any stream <br />or other body of water.
