. proposed expansion does not impact the golf course, and that valued trees are protected whenever possible. <br />3 Staff is currently drafting an agreement to be signed by the MHCC to allow this work to occur and provide <br />3� the City a ponding and drainage easement. Staff is working with both the golf course and adjoining <br />3� property owners to finalize the plant restoration plan to ensure that the plant selection is acceptable to all <br />a� parties and enough screening is provided between the golf course and the homes. <br />a; As part of the wetland expansion project, the City will be required to obtain a permit from the Minnesota <br />a: Pollution Control Agency (MPCA) for management of dredged materials. Regulations have recently been <br />a. enacted, requiring dredged materials to be tested for contamination and disposed of accordingly. Test <br />a� samples will be taken from the wetland prior to excavation, and the City will need to work with the MPCA <br />a� to meet these regulations. <br />a� This project is proposed for construction this fall. Due to the nature of the project, and that homes have <br />a� experienced flooding, staff recommends moving forward with this project at this time. Several <br />5� neighborhood meetings have been held, and residents have indicated they are in favor of a project to <br />5 improve drainage throughout their neighborhood. City staff is currently providing construction engineering <br />5; on several other city projects at this time and does not have the capacity to provide these services at this <br />5: time. Staff will be seeking assistance from the design consultant for implementation of these <br />5. improvements. <br />5! <br />5i POLICY OBJECTIVE <br />5 In 2007, the Walsh Lake subwatershed was added as a problem area to the City's Comprehensive Surface <br />5� Water Management Plan (CSWMP.) One of the goals from the City's CSWMP is to provide flood <br />�� protection for all residents and structures as well as protect the integrity of conveyance channels and storm <br />water detention areas. This project is also consistent with City water quality goals. <br />FINANCIAL IMPACTS <br />s, The estimated cost to construct the rain gardens and underground storage chamber is $310,932. The <br />s: estimated cost to complete the Rosewood Pond expansion is $100,000. This project is proposed to be paid <br />s. for using Storm Water Sewer Infrastructure Funds. Staff is working with the Rice Creek Watershed <br />s� District and Ramsey Conservation District on possible cost-sharing grants for this project. WSS has <br />� provided a proposal for design of the underground storage chamber, MPCA permit coordination, and Phase <br />1 bidding services and construction observation in an amount not to exceed $18,380. <br />STAFF RECOMMENDATION <br />s� Staff recommends construction of the Walsh Lake Subwatershed Drainage Improvements Project and to <br />�� authorize staff to advertise for bids. Staff also recommends engaging WSS and Associates, Inc. to assist in <br />� implementation of this construction project as described above. <br />7; REQUESTED COUNCIL ACTION <br />�: A motion to approve the Walsh Lake Subwatershed Drainage Improvements Project, authorize staff to <br />� advertise for bids, and engage WSS and Associates, Inc. for additional services through Phase 1 not to <br />exceed $18,380. <br />Prepared by: Kristine Giga, Civil Engineer <br />Page 2 of 2 <br />
