Pheasant Hills Preserve 12th Addn. page 2 • which lists the criteria to be considered to determine if a project has the potential for significant environmental effects —that is, if an EIS is warranted. 4410.1700 DECISION ON NEED FOR EIS. Subpart 1. Standard for decision on need for EIS. An EIS shall be ordered for projects that have the potential for significant environmental effects. Subp. 7. Criteria. In deciding whether a project has the potential for significant environmental effects, the following factors shall be considered: A. type, extent, and reversibility of environmental effects; B. cumulative potential effects of related or anticipated future projects; C. the extent to which the environmental effects are subject to mitigation by ongoing public regulatory authority; and D. the extent to which environmental effects can be anticipated and controlled as a result of other available environmental studies undertaken by public agencies or the project proposer, including other EISs. The EAW review highlighted several issues. The main environmental issues are noise and vibration from the pile driving activity during construction of the bridge, and the visual impact of the bridge. Noise: The noise from the pile driving will be unpleasant for nearby residents. It will be temporary —the duration of the bridge construction. Construction hours will be limited by a standard city requirement in all development agreements: 7:00 a.m. to 7:00 p.m. Monday through Friday; 9:00 a.m. to 5:00 p.m. Saturday; no work on Sundays or holidays. There likely will be dewatering pumps running beyond those hours. Temporary noise walls will be required around the pumps to minimize any disturbance to existing homes. Vibration: As with construction noise, this is a temporary, though unpleasant impact. A pre - construction survey and ongoing monitoring program, as well as additional fmancial security, will be required. Visual: A flat bridge design will minimize the visual impacts compared to a truss bridge. The bridge will be visible: it will be about 10 feet higher than the tops of the vegetation. The City will require the use of wooden railings, which will fit into the wooded environment. There will be a visual impact, and it will be permanent. The impact will be similar to the type and extent of changes that occur when new roads are constructed and homes are built in previously undeveloped areas. However, the bridge will be more visible than most roads because the top of the railings will be about ten feet above the vegetation tops.
