1.( t) - conveyance of suitable replacement property to satisfy the Ramsey County "no net loss" policy, as well as federal LA WCON requirements and will also require Metropolitan Council concurrence, Subject to further investigation, and based on initial contacts with the St. Paul Water Utility, the City proposes to lower the two aqueducts over a distance of approximately 400 feet to allow for the Rice Creek Parkway crossing. This is necessary to.match the grade of Rice Creek Parkway at County Road I. Further coordination with the St. Paul Water Utility will occur to assure that the offset will not negatively affect the flow in these lines. Relocation of the aqueducts will likely occur during the off-peak water usage months of October to April, and only one line will be allowed to be out of service at a gi ven time. The proposed development site requires water distribution service to the site. Trunk water main will be "looped" through Ramsey County Rice Creek North property, the development site and connected to the City of Shoreview's existing system at Schutta Road and Lexington Avenue. Construction of the water main will create a temporary disturbance to sensitive areas. The trench will be restored to the original grade and backfilled with organic materials where removed. The proposed development site trails will connect to existing trail systems outside of the project limits. The trail connection is proposed to cross Rice Creek and connect to the recently constructed Rice Creek North Corridor Trail. The exact location of the trail crossing bridge is unknown at this time. The trail alignment and crossing is expected to follow the water main trench alignment to minimize construction impacts. The final alignment chosen for the water main and trail will minimize impact to the open space, creek and wetlands. The proposed project is designed to minimize impacts to the environment to the maximum extent feasible and practicable. The southeastern portion of the U of M property is designated as scenic easement and is included within the Rice Creek North Corridor. No development is allowed in the scenic easement. The project site includes about 9 acres of wetlands. The proposed project will impact about 2 acres of wetlands within the proposed development site. Construction of the proposed Rice Creek Parkway through Rice Creek North property will affect an additional 2.8 acres of wetlands. As discussed in Section 4.1.3, unavoidable wetland impacts will be mitigated at a 2: I ratio by a combination of on-site wetland creation and public value credits. The project site includes portions of the Rice Creek floodplain. The proposed Rice Creek Parkway will encroach on 7.8 acre-feet of the IOO-year floodplain in the Rice Creek North property southwest of the project site. Compensatory storage consistent with Rice Creek Watershed District requirements will be provided. The proposed project and related Rice Creek Parkway will include a storm water management plan consistent with City and Rice Creek Watershed District requirements. In general, post-development runoff from all impervious areas and from much of the pervious areas will be routed through water quality treatment ponds prior to discharge from the project site.
