4.3.c Storm Sewer/Drainage Storm sewer exists under the permanent section of Puma Street constructed in 2018. The proposed Puma Street improvements includes construction of a permanent urban street section with bituminous pavement, concrete curb and gutter, and storm sewer improvements, including connections to an adjacent stormwater pond in the Riverstone development. 4.4 Estimated Costs / Funding Sources Staff proposes to utilize Bolton & Menk to prepare plans and specifications for the Puma Street improvements since they designed the streets and utilities for the south end of Puma Street, and since they previously surveyed the north end, meaning only minimal survey work would be required to allow design work to commence. An engineering services proposal was therefore secured from Bolton & Menk on March 17, 2020, for preparing plans and specifications, obtaining permits, and bidding the project. The proposal, which is included in Appendix B, includes a not - to -exceed fee of $53,125. This includes $5,500 for Northern Technologies Inc. to complete a Geotechnical Evaluation. The proposal also includes a not -to -exceed fee of $8,930 for construction administration and staking, which will be considered at the time bids are accepted. A preliminary engineer's estimate for the proposed Puma Street improvements was prepared by Bolton & Menk and is included in Appendix C. The preliminary project cost estimate totals $925,000, which includes $625,000 for street and trail improvements, $70,000 for storm sewer improvements, and $230,000 for trunk utility improvements. Estimated costs include 10-percent contingency and 15-percent indirect (administrative, engineering, finance and legal) costs. Based on consensus direction at the February 11, 2020, joint Planning Commission/City Council work session, a City cost contribution of one-third seemed reasonable given that the City owns 4 acres of real property fronting Puma Street, and since Puma Street is a collector street. The current cost share model is therefore based on this direction. As also discussed during the joint work session, Capstone Homes requested that the City assess them for their share of project costs benefitting their property. Conversely, AKM Farm/Paxmar does not support an assessment at this time so the Chapter 429 assessment process must be followed requiring a public hearing and acceptance of this Feasibility Report after. Several funding sources are available to pay for the City's share of street and trail project costs including the Public Improvement Revolving (PIR) fund, the Anoka County Redevelopment Authority (ACHRA), and Municipal State Aid (MSA) funds. All project costs required to extend trunk utilities along Puma Street are proposed to be paid through City sewer and water funds. The developer's share of these costs will be recovered through trunk fees at the time of development. 4.5 Preliminary Schedule A preliminary project schedule is included in Bolton & Menk's proposal in AppendixB Feasibility Report Puma Street Improvements City of Ramsey Project No. 20-04 6
