• the project area. The survey was submitted to the State Historic Preservation Office (SHPO) for comment. The SHPO raised no issues with the survey. • • Property Boundary, Regional Park Reserve The preliminary plat, Figure 11 in the EAW, shows the property boundaries. The northern border of the property cuts off approximately 30 feet of the northern tip of the island. Property north of this line is within the regional park reserve and is owned by Anoka County. This is within an area acquired by the City by eminent domain in 1997 -98 and conveyed to Anoka County. The surveying needed for the development project was more extensive and detailed than what was prepared for the eminent domain action. The more detailed survey revealed that the property border cuts off a tip of the island. While this is unfortunate and creates a clumsy situation, it has no serious effect on the park reserve or the proposed project. The project grading plan does not include disturbing the tip of the island that is north of the boundary line. SUMMARY OF ISSUES The main environmental issues are noise and vibration from the pile driving activity during construction, 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. Vibration: As with construction noise, this is a temporary, though unpleasant impact. A pre - construction survey and ongoing monitoring program, as well as additional financial security, will be required. Visual: A flat bridge design will minimize the visual impacts compared to a truss bridge. While the bridge will be visible, it will be only about 10 feet higher than the tops of the vegetation. The City can require the use of wooden railings, which will fit into the wooded environment. There will be a visual impact, and it will be permanent. However, the extent of 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. In addition, the following issues will require future attention or enforcement and will be addressed as part of the plat review and approval: 1. The City will require a specific and extensive tree preservation plan for the plat and individual plans for custom graded lots. These are required in the City's newly adopted subdivision and zoning ordinances. DRAFT July 1, 2004 Pheasant Hills Preserve 12th Addn. EAW Record of Decision page 6
