Alpine Drive trail connection (CSAH 5 (Nowthen Blvd) to Krypton Street) —
<br />Numerous trails exist in the project area but a gap exists in the trail system north of Alpine Drive between CSAH 5 (Nowthen Blvd) and Krypton Street where
<br />the trail abruptly ends approximately 100 feet west of Krypton Street. Staff has always intended to connect this gap, and the opportunity now exists to
<br />cost-effectively connect this gap with this project. Staff therefore recommends providing Anoka County with the requested drainage easement over the City's
<br />0.57 acre parcel in Alpine Acres for the County's use as a stormwater ponding facility. This will then be in exchange for Anoka County preparing the plans and
<br />specifications and procuring the necessary right-of-way and temporary construction easements to construct the trail connection, which is approximately 700 feet
<br />in length. Anoka County staff soon plans to meet with the abutting property owners to discuss associated tree removals and right-of-way/temporary construction
<br />easement needs, including potential compensation for these items.
<br />The estimated construction cost for the trail connection is $17,000. There will also likely be additional costs for securing the necessary right-of-way and
<br />construction easements (+/- 2 feet of right-of-way and temporary construction easements) and compensating for tree removals, though these costs are still
<br />unknown. Anoka County has designed the trail connection and incorporated it into their construction plans, and they would bid and inspect the trail during
<br />construction, all of which provide additional benefit to the City.
<br />The County therefore proposes the following cost sharing methodology related to the stormwater ponding and trail connection. The City will provide the
<br />necessary drainage easement over our 0.57 acre platted parkland property to allow the County to use the land for stormwater ponding, in exchange for which the
<br />County will pay to secure the necessary right-of-way and temporary easements to construct the trail connection, as well as provide compensation for tree
<br />removals as needed. The City will then pay all costs to construct the trail, although the County has also agreed to apply federal funds to the trail (federal funds
<br />are currently covering about 60% of construction costs) instead of requiring the City to pay 100% of construction costs per standard practice for work not
<br />required for their project. This will result in an estimated total cost to the city of $6,800 to construct the trail connection with this project, thereby saving the City
<br />about $10,200.
<br />Trunk watermain connection / loop —
<br />City staff recommends constructing a watermain connection to loop the trunk watermain system in this area to provide additional flexibility for maintaining the
<br />trunk watermain lines. The watermain would be constructed under the new trail connection north of Alpine Drive between CSAH 5 (Nowthen Blvd) and
<br />Krypton Street, which will avoid the need to reconstruct any portion of Alpine Drive outside the current project limits. The estimated cost for this work is
<br />$40,000.
<br />Existing Trails —
<br />Any existing trails impacted by this project will be replaced with identical trail sections having the same width and pavement section, and new ADA compliant
<br />pedestrian curb ramps will be installed on all pedestrian facilities in all 4 corners of the intersection.
<br />Alpine Drive Culvert Replacement (separate project) —
<br />Staff wants Council to be aware that an RCP equalizer pipe crossing Alpine Drive about one -quarter mile west of CSAH 5 was recently repaired and needs to be
<br />replaced. Since the intersection of CSAH 5 (Nowthen Blvd) and Alpine Drive will be temporarily closed during this project, staff would propose to replace the
<br />pipe at that time to avoid disruptions to traffic and to save on traffic control costs. This work, which is not included in the CIP and would be completed under
<br />separate contract, is estimated to cost $35,000.
<br />Estimated Proiect Costs:
<br />The estimated construction cost of the total project is $1,692,666.35. Federal funds are available for this project and are capped at $936,000. The federal funds
<br />shall be split based on the ratio of eligible cost incurred by each party to the total eligible project cost. Eligible costs are the costs of items that can participate in
<br />federal funding as shown on Exhibit B of the attached JPA.
<br />The total estimated construction cost to the City is $385,918.61 (prior to application of federal funds available). After federal funding percentage is applied, the
<br />cost to the City for our share of the construction costs of the project is $195,140.81 ($385,918.61 minus $190,777.80, the federal funds available to the City).
<br />The City participation in construction engineering will be at a rate of eight percent (8%) of our designated construction share of $385,918.61, which equals
<br />$30,873.49. In summary, the total City share of this project before federal funds are applied is $296,883.36 which includes construction and construction
<br />engineering costs. The total cost to the City after federal funds are applied, including construction engineering which is not eligible for federal funding, is
<br />$226,014.30.
<br />Upon award of the contract, the City will need to pay the County, upon written demand by the County, ninety five percent (95%) of its portion of the cost of
<br />the project, which is estimated at $214,713.58. Prior to billing, this estimate will be updated by the County to reflect the actual bid prices as awarded. An
<br />updated cost estimate shall be provided to the City at the time of billing. The City's share of the cost of the project shall include only construction and
<br />construction engineering expense and does not include engineering design and administrative expenses incurred by the County.
<br />Upon final completion of the project, the City's share of the construction cost will be based upon actual construction costs. If necessary, adjustments to the
<br />initial ninety five percent (95%) charged to the city will be made in the form of credit or additional charges to the City's share. Also, the remaining five percent
<br />(5%) ofthe City's portion ofthe construction costs shall be paid.
<br />Public Works Committee Recommendation —
<br />Staff from the City and Anoka County reviewed the proposed improvements with the Public Works Committee on Tuesday, December 3rd. The following is a
<br />summary of the comments received by the Committee.
<br />• Access modifications — The Committee generally agreed that they would prefer that raised concrete median islands not be constructed on County Roads
<br />within City limits. However, in this case it seems to be more acceptable given that County staff met with the affected property owners who generally
<br />supported the access restrictions created by the raised medians because of the increased safety provided by them.
<br />. Stormwater ponding — The Committee was generally supportive of providing a drainage easement over this property for use as stormwater ponding.
<br />• Alpine Drive trail connection (CSAH 5 (Nowthen Blvd) to Krypton Street) — Two of the three Committee members (CM Backous and CM Kuzma)
<br />supported constructing this trail connection due to the regional benefits provided by this trail connection. However, CM Riley was not supportive of
<br />constructing the trail connection as two of the abutting property owners recently contacted him to note their objections due to reduced green space along
<br />their front yards, as well as potential impacts to their driveway alignments / grades. If Council approves the trail connection, staff will work with Anoka
<br />County to ensure that the proposed driveway alignments / grades will meet the property owner's needs.
<br />. Trunk watermain connection / loop — The Committee was generally supportive of constructing the trunk watermain connection given the benefits
<br />provided by looping the system as noted above.
<br />The Public Works Committee recommended City Council approval of the draft Joint Powers Agreement as drafted by a vote of 2 to 1. CM Riley voted in the
