East Airfield Development Area Draft Environmental Assessment East Airfield Development Area Draft Environmental Assessment ON-SITE ALTERNATIVES ENVIRONMENTAL IMPACT DETERMINATION – SUMMARY TABLE Category Significance Threshold Significant Impact No Significant Impact with Mitigation No Significant Impact Project exceeds one or more of the National Ambient Air Quality Air Quality X Standards (NAAQS) Biotic Resources Action effect on population dynamics X Action effects on sustainability and reproduction rates X Compatible Land Use Section 4(f) Resources Federally-listed Endangered or Threatened Species Natural and artificial mortality The minimum population size needed to maintain the affected populations Same threshold as noise – A DNL 1.5 dB increase at a noise sensitive use within the DNL 65 dB Project constitutes a “use” or “constructive use” of potential Section 4(f) properties USFWS or NMFS determines that the action would likely jeopardize the continued existence of a federally-listed species under the ESA Destruction or adverse modification of designated critical habitat under the ESA Energy Supply, Natural Resources, and Sustainable Project energy demands exceed available supply. X Design Floodplains Notable adverse impacts on natural and beneficial floodplain values X would occur Hazardous Materials Action involves a property on or eligible for the National Priority List X The sponsor would have difficulty meeting applicable local, state, or X Federal laws and regulations hazardous materials. There is an unresolved issue regarding hazardous materials X Historic and Archeological Action adversely affects a protected property under NHPA X 1 SHPO or THPO findings of adverse affects on protected property. X Noise A DNL 1.5 dB increase at a noise sensitive area within the DNL 65 dB X Social Impacts The action would cause extensive relocation, but sufficient X replacement housing in unavailable The action would cause extensive relocation of community businesses X that would cause severe economic hardship for affected communities. 2 Substantial reduction in Level of Service for roads serving the airport X area. Substantial loss in community tax base. X Water Quality Action would not meet water quality standards. X 3 Wetlands Adversely affect a wetland’s function to protect the quality or quantity of a municipal water supply, including sole source aquifers and a X potable water aquifer. Substantially alter the hydrology needed to sustain the affected wetland’s values and functions or those of a wetland to which it is X connected. Substantially reduce the affected wetlands’ ability to retain floodwaters or storm runoff, thereby threatening public health, safety or welfare. 4 X The last term includes cultural, recreational, and scientific public resources or property. Adversely affect the maintenance of natural systems supporting wildlife and fish habitat or economically-important timber, food, or fiber X resources of the affected or surrounding wetlands. Promote development that causes any of the above impacts. X X X X X X X 5 Be inconsistent with applicable State wetland strategies. X Cumulative Impacts Cumulative effect of the Proposed Action will exceed the significance X Source of Significance Thresholds: FAA Order 5050.4B 7 SCHENKELSHULTZ 8 SCHENKELSHULTZ
