HomeMy WebLinkAboutBSP Master Plan MODModification to Sports Park Master Plan – Municipal Groundwater Well Project Background The City has been pursuing development of a groundwater supply to expand its available municipal water supply to support and allow for continued City growth. A groundwater investigation was initiated in 2015 by the engineering consulting firm of Respec. Investigation conclusions found a significant groundwater aquifer exists under the Bozeman Sports Park. The investigation work to-date has been a desktop exercise utilizing existing publicly available well logs, streamflow data, and geologic mapping to develop a hydrogeologic model. The City has not yet drilled any exploration or test wells into the aquifer under the Sports Park to validate the desktop findings that large quantities of high quality groundwater are available for development. This physical groundwater testing data is necessary, in conjunction with the hydrogeologic model, to support an application for a beneficial water use permit from the MT DNRC. This permit is required under the Montana Water Use Act in order to obtain a legal water right to appropriate groundwater for municipal purposes. Municipal Groundwater Well at Sports Park The attached exhibit provides a conceptual plan level depiction of a municipal groundwater well facility at the Sports Park. The facility would occupy a portion of the southeast corner of the park near the intersection of Flanders Mill Road and Oak Street. Essentially, the groundwater facility could eliminate the portion of the current Sports Park Master Plan programmed as a dog park depending upon the number of wells drilled. Two wellhead locations are shown, which generally represents the maximum amount of area needed for the groundwater facility. Depending on the yield of the aquifer, two wells may be needed to produce sufficient quantities of groundwater. The number of municipal wells constructed will be determined once a test well is drilled and aquifer testing data is acquired and analyzed. A 100’ radius wellhead isolation zone required pursuant to DEQ regulations is shown on the exhibit for each wellhead. The isolation zone must be kept free of encroachments that may cause contamination of the groundwater aquifer. The municipal groundwater well facility includes the following major components: Primary groundwater pumping well located within a 10’x10’ well house Potential secondary groundwater pumping well located within a 10’x10’ well house 100’ wellhead isolation zones for each well A 3,000 square foot building annex to the master planned park maintenance facility that houses chlorination equipment to disinfect the groundwater supply and treatment equipment needed to meet secondary drinking water quality standards under the federal Safe Drinking Water Act. Pipelines to connect each wellhead to the 3,000 square foot treatment building A pipeline connecting the treated groundwater to the City’s existing public water supply main in either Flanders Mill Road or Oak Street. It must be noted that the dimensions of the well houses and treatment building are conceptual only and subject to change. Final dimensions will be determined during final design of the groundwater facility and be reviewed and approved under the City’s plan review process prescribed in its municipal code. The purpose of the modification to the Sports Park Master Plan is to reserve the area identified on the concept exhibit for a municipal groundwater facility. The ultimate area needed will be determined once the test well and aquifer testing is complete. What is shown is the maximum area that could be needed for the facility for Sports Park master plan modification purposes. Open Space Bond A legal question was presented to the City Attorney asking if a municipal well and its appurtenant infrastructure (foregoing bullets) at the Sports Park is legally permissible given the property was acquired under the Montana Open Space Land Act. A legal review was conducted of the general obligation bond question that was put before the City electorate during the 2012 general election in light of a municipal groundwater facility occupying a portion of the Sports Park property. The legal opinion is that a municipal groundwater facility is consistent with the GO bond question and the Open Space Bond Act and does not trigger the Act’s land conversion requirement. Opportunities for Public Works Department and Parks Department Collaboration Fair Market Value The Public Works Department is committed to providing fair market value compensation as determined by a qualified appraiser for the land area that the municipal well facility occupies. The income generated would be reserved for future Sports Park improvements programmed on the current park master plan. The Parks Department supports this proposition. Opportunities in Constructing Co-located Park Improvements There is an opportunity for Public Works and Parks to collaborate on the design and construction of planned building and site improvements at the southeast corner of the park. Proportionate cost share of the design and construction of the maintenance building and groundwater treatment building could be arranged; same for site improvements such as access, parking, sidewalk and landscaping. It may be that the groundwater facility is constructed in advance of the maintenance building given available Parks Department capital funding. Should this occur Public Works is committed to working collaboratively with Parks on a detailed site design and then constructing surface improvements needed to support the groundwater facility use and future park maintenance building use. Work Sequence and Preliminary Schedule for Municipal Groundwater Facility A series of actions are needed to ultimately secure a beneficial water use permit for the municipal groundwater facility. These actions are provided in sequential order below along with a preliminary schedule. 1) Obtain City Commission approval of a Modification to Sports Park Master Plan for the municipal groundwater facility use. [September 2020] (Note: an assurance is needed before significant public monies are spent for the test well and aquifer testing.) 2) Respec to prepare test well construction bid documents and assemble an aquifer testing and data collection plan. [October 2020 – December 2020] 3) Bid and award test well construction contract. [January 2021 – March 2021] 4) Drill test well and perform aquifer testing and data collection [April – May 2021] (Note: If aquifer testing reveals unsatisfactory groundwater quantity and/or quality, Public Works will focus its groundwater development efforts on other potential groundwater sites and abandon the Sports Park for use as a groundwater facility) 5) Prepare application for beneficial water use permit for submittal to MT DNRC and receive ‘correct and complete’ application determination. [June 2021 – December 2021] 6) Prepare and receive site plan approval for groundwater facility and parks maintenance facility. [January 2021 – March 2021] 7) Perform land appraisal of Sports Park land area needed for groundwater facility identified in the approved site plan and transfer funds. [April 2021] 8) DNRC review of correct and complete beneficial water use application, issuance of Preliminary Determination to Grant, and close of objection period. [January 2021 – May 2021] 9) Approval of beneficial water use permit by MT DNRC [June 2021] (note: DNRC approval assumes no objections to the permit were received, thus avoiding a contested case. A contested case decision is a quasi-judicial DNRC administrative proceeding that is subject to appeal within the MT judicial system. Remainder of schedule is contingent upon the date the beneficial water use permit is secured.) 10) Prepare detailed engineering design of groundwater facility and obtain MT DEQ design approval. [June 2021 – September 2021] 11) Prepare groundwater facility, including site improvements, construction bid documents and award construction contract. [October 2021 – January 2022] 12) Construct groundwater facility [February 2022 – July 2022] 13) Put groundwater supply to use.

BACKGROUND: Resolution No. 4521 was unanimously approved by the Commission April 14, 2014 for the allocation of Trails, Open Space and Parks (TOP) bond funding in an amount not to exceed $7,500,000, “for the acquisition of park land and development of the Bozeman Sports Park Project (“Park Project”), which requires the assistance of a professional design and engineering team. The resolution allocated up to (i) $2,100,000 for the acquisition of approximately 80 acres of park land; (ii) up to $1,788,000 for infrastructure improvements as stated in the Commission motion adopted April 7, 2014; and (iii) the remainder of the $7,500,000 for park development and construction through a yet to be completed park master plan.” The land purchase was completed in 2014 for $2,022,413 leaving $3,689,587 for design and construction of park improvements, reserving the $1,788,000 for infrastructure. The master plan was developed through an interactive design process with a public input committee comprised of key stakeholders (Bozeman Sports Park Foundation, Gallatin Valley Land Trust, Run Dog Run, City departments, and representatives from the Recreation and Parks Advisory Board, and the Bozeman School District). The Consultant team led the process by developing three alternatives, which were refined into the preferred Preliminary Concept Plan (Attachment A). The Master Plan was recommended for approval by the Recreation and Parks Advisory Board on February 11, 2016. A complete review by the Development Review Committee was completed and the Bozeman Sports Park Master Plan was recommended for approval on April 27, 2016. The process for hiring a General Contractor Construction Manager was then followed, bringing on a firm to work with the design team and address issues associated with phasing and construction feasibility. The overall layout of the master plan features has been finalized with future phases to be determined by funding availability. 442 The Master Plan components include: • 14 multi-purpose sports fields • Central park plaza area featuring restrooms, vending, storage playground, picnic shelter(s), open play areas, and splash pad • Maintenance yard with a storage building and parking • Dispersed play items and picnic sites • Wayfinding station and small restrooms at north and south park entries • Interconnecting trails and access points • 2-acre dog off-leash park and agility course • Spectator areas with room for shade structures • Irrigation storage pond • Parking for up to 700 vehicles (including overflow areas) • Perimeter sidewalks and street trees • Relocated Farmer’s Canal irrigation pipe and overflow • Landscaping, irrigation, and stormwater detention with “green infrastructure” components Phase I construction will include a minimum of 4 fields, parking, stormwater detention, a wayfinding station (informational kiosk) and restroom building (Land and Water Conservation Fund grant), basic vending facility (pending donation), landscaping and irrigation. Additional fields (possibly 2 – 4) are expected to be funded through donations to the Bozeman Sports Park Foundation.
