• • 28. Impact on infrastructure and public services. Will new or expanded utilities, roads, other infrastructure or public services be required to serve the project? El Yes ❑ No. If yes, describe the new or additional infrastructure or services needed. (Note: any infrastructure that is a connected action with respect to the project must be assessed in the EAW; see EAW Guidelines for details.) A private drive and bridge is proposed as a part of this project to provide access to the seven lots on the island. The bridge would be approximately 300 feet long. The bridge as proposed would be supported by 150 foot steel trusses. The 150 feet spans come in three pieces. One pier is proposed in the center of the bridge to provide center support for the four 150 foot trusses. The bridge will be supported on driven piles. The piles will driven at each end abutment and at the center pier. The piles will be driven approximately 40 feet to 65 feet below present grade. The private drive will cross the bridge and continue along the south side of the island. On the island, the proposed pavement width is 20 feet, with no curb and gutter. This reduces impervious surface. Stormwater will be handled through swales, infiltration, and ultimately ponding. Sewer and water facilities will also be extended and installed to City specification to serve this project. A lift station will be required for sanitary sewer service. The specific location of the lift station on the island has yet to be determined. The bridge, drive, and utilities will be owned and maintained by the homeowners' association. The City will require provisions in the development agreement to enable the City to step in and effect repairs, should the association fail to maintain the infrastructure, and assess the cost to the property owners. This development is not expected to significantly impact the existing public infrastructure. City standard cul -de -sac radii are proposed to serve as adequate turn around area for emergency vehicles and snow removal equipment. The proposed bridge will have a 9 -ton weight capacity. The addition of eight homes will not overburden the delivery of public services such as police and emergency services. The bridge and road will be built to accommodate fire trucks and other vehicles. Any damage to existing streets caused by construction traffic must be repaired at the developer's cost. Though the site does not experience a great number of watercraft, some people do use canoes in the area. If the bridge is high enough above the water surface, canoe use will not be prevented. 29. Cumulative impacts. Minnesota Rule part 4410.1700, subpart 7, item B requires that the RGU consider the "cumulative potential effects of related or anticipated future projects" when determining the need for an environmental impact statement. Identify any past, present or reasonably foreseeable future projects that may interact with the project described in this EAW in such a way as to cause cumulative impacts. Describe the nature of the cumulative impacts and summarize any other available information relevant to Environmental Assessment Worksheet Page 22 Pheasant Hills 12'" Addition
