Feasibility Report Northeast Lino Lakes Drainage Improvement Project WSB Project No. 02029-790 Page 11 Given the complexity of the project it is anticipated that the City and staff will need to meet with the above agencies individually in order to facilitate permit approvals. 4.6. Right-of-Way / Easements Right-of-way needs will be evaluated during final design. It is anticipated that some temporary construction easements will be required. Easement acquisition for the pipeline is anticipated: the easements related to the regional storage basins will be acquired as part of the platting process for individual developments. 4.7. Project Phasing The project will be constructed in several phases (Appendix A, Figure 8), as funding and land development allows. The project will be constructed from downstream to upstream, starting with the new Peltier Lake outfall and finishing with upstream regional storage facilities. Phase 1 will include construction of the new outlet at Peltier Lake and the installation of the 72- inch storm sewer from Peltier Lake Drive to 20th Avenue. Once this outlet pipe is installed, the immediate neighboring properties can develop and discharge treated stormwater to the outlet pipe. Development of the regional stormwater facility between Peltier Lake Drive and 20th Avenue would need to be constructed concurrently with any development. The new 72-inch storm sewer will also provide an outlet for the proposed ponding facility being constructed between 20th Avenue and I-35E, also part of Phase 1. Phase 2 will include the installation of a new 60-inch crossing under I-35E and an extension of the storm sewer beyond the MnDOT right-of-way to allow for future extension of the sewer along Otter Lake Trail. Phase 3 would be constructed concurrently with the Otter Lake Trail extension and includes expanding the storm sewer system east of I-35E to the Otter Lake Trail extension and within the proposed right-of-way. Future phases include construction of additional regional storage facilities, water quality features, recreational enhancements, and additional storm sewer infrastructure as needed for development. The timing of these features will depend on individual landowners and development interests. At all times during project construction and phasing, upstream drainage will be maintained by realigning the county ditches, at the developers expense, or leaving them in place for future abandonment when the study area is fully built out. 4.8. Private Utilities The Koch Pipeline Company has three crude oil pipelines that run through the study area, roughly from 20th Avenue and 80th Street in the northwest to Main Street at the Hugo border. The proposed 60-inch crossing under I-35E avoids the Koch pipeline, but final design of the storm sewer infrastructure east of I-35E will need to ensure there are no conflicts with the
