2 1.0 PROJECT DESCRIPTION Sourdough Creek changes to Bozeman Creek after crossing an imaginary line while flowing beneath Kagy Boulevard. The character of the Creek changes as well. As the Creek flows north towards downtown Bozeman the amount of pollutants entering the Creek increases proportionally with an increase in urbanization. Pollutants entering the Creek abide by no geographical boundary and therefore by the time water from Bozeman Creek reaches the East Gallatin River the variety and concentration of pollutants has increased exponentially. Water quality in Bozeman Creek has been impaired to such a degree that the Montana Department of Environmental Quality has indicated that certain reaches of Bozeman Creek may not be able to support aquatic life, a cold water fishery or primary recreational contact. An investigative study conducted by a local Environmental Engineering Firm confirmed Bozeman Creek has exceeded Total Maximum Daily Load (TMDL) levels for nutrients, suspended sediment and E.coli bacteria. Most of the pollution entering the Creek occurs through stormwater runoff and illicit discharges. Some of the concerning pollutants found in stormwater runoff and illicit discharges include suspended sediment, strains of bacteria, fertilizers, herbicides, pesticides, oils and grease, heavy metals and volatile organics. In attempt to mitigate removal of these contaminants from stormwater runoff kN, are proposing for our Bozeman Creek Neighborhood a Community Park that will include a .elute of the art stormwater treatment system. y ie s a er treatmen s m will effectively treat stormwater runoff from 45 acres of the Bozeman Creek Neighborhood and overflow from a pond located on the Valley View golf course property, south of the Bozeman Creek Neighborhood. Currently overflow from the pond is conveyed through the Bozeman Creek Neighborhood stormwater infrastructure and empties into Bozeman Creek at the East Lincoln Street outfall. Rate of flow has been measured at 48 gallons per minute during normal base flow conditions and the flow is continuous year round. The proposed Bozeman Creek Neighborhood Community Park and Water Quality Improvement project is a shovel ready project with many years of broad based community support. All research, field engineering studies, architectural designs and feasibility investigations have been completed. The storm water treatment system will provide the city of Bozeman with a cost effective demonstration pilot project that can be replicated in other stream side neighborhoods throughout the city. The Bozeman Creek Neighborhood Community Park will fulfill the objectives of the Bozeman's Parks and Trails Bond by improving water quality in Bozeman Creek and creating a connector trail that links up to the existing Galligator and Burke Park community trail system. Additionally as an educational facility (outdoor classroom) the Bozeman Creek Community Park and accompanying Best Management Practice (BMP) storm water (Water Quality Treatment) system will help cultivate a visitor's interest in science, technology, engineering and math (STEM) principles. The Community Park will serve as an educational outdoor classroom for students and community citizens of all ages. There are approximately 7 schools within walking distance of the proposed Park. The Community Parks Water Quality Treatment facility will help the City of Bozeman keep in compliance with the Phase II National Pollutant Discharge Elimination System (NPDES) permit for discharges from 3 its (MS4) Municipal Separate Storm Sewer System. New Federal and State regulations require action by the City of Bozeman to minimize pollution carried by stormwater runoff. The Montana Department of Environmental Quality regulates stormwater runoff through the United States Environmental Protection Agency (EPA) stormwater Phase II permitting process of the Clean Water Act. In adherence to the Phase II permit of the Clean Water Act, Bozeman has developed a Stormwater Management Program, which involves six minimum control measures that are meant to control storm water pollutants to the maximum extent possible. Three control measures that will be addressed through the creation of a Bozeman Creek Community Park and the Bozeman Creek Water Quality Improvement project are ➢ Public Education and Outreach ➢ Public Participation/Involvement ➢ Illicit Discharge Detection and Elimination The Bozeman Creek Community Park Water Quality Treatment project will achieve these control measures through design and demonstration. The Park will also help the Bozeman community waste water treatment plant keep in compliance with the facilities state issued discharge permit by reducing water quality impairments that occur upstream of the East Gallatin River treatment facility. The Bozeman Creek Community Park has been designed to be supportive and consistent with the goals and objectives of the Bozeman Creek Neighborhood Plan adopted by city commissioners on 12/l/ 2003, City of Bozeman Storm Water Management Program ordinance adopted on 4/16/2007, Bozeman Creek Storm Water Demonstration Project Evaluation Plan, adopted by the Gallatin Local Water Quality District, Montana Department Of Environmental Quality (Watershed Protection Section) 6/25/2007and the Bozeman Creek Enhancement Plan adopted by the City of Bozeman's Commissioners on 7/23/2012. The Bozeman Creek Community Park and Water Quality Improvement Project has been presented to the City of Bozeman Public Works Director, Engineering and Planning, Recreation Department Director and City Manager. The Bozeman Creek Community Park and Water Quality Treatment project will be developed through the following Scope of Work ➢ Installation of state of the art storm water treatment system ➢ Construct lined overflow detention pond ➢ Install landscape vegetation and irrigation system ➢ Create educational interpretive kiosks. Develop an interpretive educational tour and literature packages that can be taken home ➢ Construct a trailhead and viewing area. Install park benches, and in place exercise and stretching stations 4 ➢ Establish a maintenance program. Develop a sampling and analysis plan with oversight from the City of Bozeman, Local Water Quality District and Montana Department of Environmental Quality 2.0 PROJECT LOCATION The Bozeman Creek Community Park will be centrally located within the Bozeman Creek Conservation corridor. The corridor is approximately 106 acres in size and is bordered by Kagy Boulevard to the south, Ice Pond Road to the north, Church Avenue to the east and South Wilson Street to the west. More specifically the Community Park will be located within the 400 block of East Lincoln Street east of South Rouse, within the East Lincoln Street right-away and adjacent private property, north of the east Lincoln Street Right-Away. Part of the project is located on the applicant's property. The property was preliminarily approved in 1998 as the 3 lot Minor Suiter subdivision. The project site lies approximately 400 feet to the west of Bozeman Creek. 3.0 BUDGET (Engineers Estimate) Scope of Work Quantity Unit Unit Cost Total Cost LAND ACQUISITION Property purchase(survey,appraisal, public 1 LS $5.70 sq ft $87,800.00 meetings, permits,recording) subtotal $87,800.00 ENGINEERING AND DESIGN Final engineer and architectural design 1 LS $3,100.00 $3,100.00 Construction/Materials Testing 1 LS $3,725.00 $3,725.00 Oversight/project management 1 LS $16,158.00 $16,158.00 subtotal $22,983.00 INFRASTRUCTURE Stormwater treatment unit 1 Each $63,185.00 $63,185.00 Storm water Manhole 1 Each $2,500.00 $2,500.00 Flow Control Structure 1 Each $3,500.00 $3,500.00 24" PVC Schedule 40 90 LF $50.00/LF $4,500.00 subtotal $73,685.00 CONSTRUCTION Excavation filtration system installation 1 LS $29,540.00 $29,540.00 detention pond temporary by-pass feature geomembrane liner in Installation detention pond 1 LS $17,270.00 $17,270.00 landscape, rock,trees and bushes 1 LS $14,780.00 $14,780.00 5 irrigation system 1 LS $9,658.00 $9,658.00 Construction trail head 1 LS $4,678.00 $4,678.00 educational kiosks 1 LS $4,167.00 $4,167.00 exercise and stretching equipment 1 LS $2,397.00 $2,397.00 subtotal $82,490.00 MONITORING Water quality sampling and analysis (4)/yr Each $912.00 $3,648.00 Water Quality biannual report production (2) /Yr Each $1,786.00 $3,572.00 and presentation subtotal $7,220.00 MAINTENANCE floatable trash removal (4) /Mnth Each $180.00 $720.00 sediment removal(vac truck)sediment disposal (2) /Yr Each $789.00 $1,578.00 subtotal $2,298.00 INCIDENTAL S Development educational outreach tour/workshops 1 LS $2,985.00 $2,985.00 Filter replacement every 6 yrs LS $12,875.00 $12,875.00 dependant on loading rates subtotal $15,860.00 TOTAL $292,336.00 4.0 FUNDING REQUESTED SOURCE OF FUNDING AMOUNT APPLICATION DATE REQUESTED City of Bozeman TOP Fund $150,000.00 March 15, 2014 City of Bozeman, Storm Water Utility $107,513.00 Gallatin, Madison Trout Unlimited $12,000.00 Valley View Golf Course $10,000.00 Bozeman Deaconess Health Services $10,000.00 NorthWestern Energy $5,000.00 TOTAL $294,513.00 6 5.0 FUNDING and ASSISTANCE RECIEVED Source of Funding Type of Funding Value of donated services Services Confluence Consulting In-Kind donation $17,600.00 GIS data mapping, hydrologic investigation, engineering design HKM/Dowl Engineering In-Kind donation $12,900.00 Engineering design, surveying Pure Water Technologies In-Kind donation $2,300.00 Water quality Bridger Analytical sample collection and analysis Rogue Pony Architects In-Kind donation $9,500.00 Architectural rendition Gossel Appraisals In-Kind donation $2,700.00 Project Site appraisal Greenspace Landscaping In-Kind donation $1,900.00 Landscape design and proposal Contech Environmental In-Kind donation $2,870.00 Engineering design, onsite analysis feasibility review and recommendations Manion Family(Applicant) In-Kind donation $67,000.00 Project development, research, Transfer of Development Rights,trail easement dedication NorthWest Energy In-Kind donation $39,000.00 Removal of approximately 27 tons of concrete and asphalt materials from the banks of Bozeman Creek across the creek from the outfall of East Lincoln Street TOTAL $155,770.00 7 6.0 OPEN SPACE/NATURAL AREAS The Bozeman Creek Community Park will be centrally located within the Bozeman Creek Conservation corridor. The corridor area is approximately 106 acres in size with a housing density of less than 1 house per 10 acre. The corridor contains some of the most intact wildlife and riparian habitat within the City of Bozeman's corporate boundaries. To protect this area a Bozeman Creek Neighborhood Plan was adopted by the City Commission in 2003. The Plan was created to facilitate preservation of this natural area through the Purchase of Development Rights, Conservation Easements and Fee Title Acquisition. The Bozeman Creek Community Park will be located on a parcel land that has had Development Rights Transferred and a new dedicated trail easement established. A great deal of effort will be expended to naturalize this parcel of land. A large number of trees will be planted and surface water detention features created within the boundaries of the Bozeman Creek Community Park. 7.0 PARKS Bozeman Creek Community Park will become Bozeman's first community Park to specifically address environmental impacts to Bozeman Creek, with a shovel ready mitigative solution. Visitors of all ages will be provided hands on opportunity to learn more about water quality issues affecting Bozeman Creek. The project will illustrate how these issues can be mitigated through the use of state of the art water treatment technology. The Parks proximity (walk able distance) to a number of schools in the area makes it a great location for an outdoor environmental classroom. The Bozeman Creek Community Parks Water Quality Improvement Project has been developed through science, technology, engineering and math (STEM) principles. Students of all ages have these principles built into their academia and are expected to understand how STEM principles are used to solve real world problems. The applicant a hydrologist and water quality specialist will be available to lead educational tours. Educational kiosks will be constructed to further explain the importance of the Parks dual purpose of naturalizing an urban landscape and how a storm water treatment system works. As visitors sit on park benches they will experience a beautiful uninterrupted view of the Bridger Mountains to the north east and view wildlife as it moves through the Park. Some stretching and in-place exercise stations are planned for the Northwest corner of the Park. 8.0 TRAILS The Bozeman Creek Community Park would be centrally located between the Galligator trail 300 yards to the west and Burke Park trails approximately 1/4 mile to the East. A spur from the Galligator trail through Cristie Park could easily be established to facilitate a connective trail system to the west. A donated Conservation Easement lies 250 yards to southeast of the proposed park. Due to the wildlife rich character and riparian habitat of this corridor great care would be taken to not encroach upon areas that are well known feeding and bedding areas. Recently the applicant has Transferred Development Rights from this parcel of land and dedicated a 4,400 (40ft x 11Oft) sq ft trail easement to the City of Bozeman. This trail travels in a north to south direction along the applicant's west property boundary. This trail head is the first segment of a trail within the Bozeman Creek corridor. This recently established trail head could 8 provide a catalyst for other land owners to follow in establishing new trail easements north and south across their properties. 9.0 STREAM ENHANCEMENT/WATER QUALITY Bozeman Creek in addition to 15 other streams that flow through Gallatin County provide the headwater flows for the East and West branches of the Gallatin River. The Montana Department of Environmental Quality (MDEQ) has listed these 16 streams as impaired according to water quality records listed in a MDEQ (303) d database. Bozeman Creek impairments include high levels of phosphorous, nitrogen, sedimentation/siltation and pathogens Escherichia coli (E. coli) bacteria. A Total maximum Daily Load (TMDL) study was conducted to determine the degree of impairment. In conclusion of the TMDL study it was determined that phosphorous, nitrogen and sedimentation/siltation and E. coli bacteria are at such concentrated levels that current pollution controls are not sufficient to attain or maintain applicable water quality standards that are needed to support aquatic life, a cold water fisheries or primary contact recreation. E. coli bacteria levels have exceeded the primary contact recreation levels of 125 colony forming units (CFU) / 100 ml sample by an average of 2,000 %. These dangerous levels commonly occur from Kagy Boulevard Park to North Rouse Avenue and Tamarack Street. A Community Survey conducted by the Bozeman Creek Enhancement Committee in 2011 overwhelming concluded that improving water quality in Bozeman Creek was the number one priority that should be undertaken in order for this resource to be considered a useable community asset. NorthWest Energy has taken a lead interest in this priority by removing seventeen, 9 cubic yard dump trucks full of asphalt and old sidewalk, curb and gutter debris from the stream banks of Bozeman creek, at their substation, directly across from the project site. The Bozeman Creek Community Park Water Quality Improvement Project will significantly improve stream habitat that is capable of supporting aquatic life, create environmental conditions that enhance the viability of a cold water fisheries and of equal if not most important ensure safe primary recreational contact for all those who recreate in the creek. The Bozeman Creek Water Quality Improvement Project will remove pollutants from water through a 3 step process ➢ Trash rack to remove floatable debris ➢ Hydrodynamic vortex oil/grit separator to remove sediment and suspended solids ➢ Media blend membrane filter to remove bacterial pathogens Component Constituents removed Percent removal Trash rack filter Floatable debris 100% Hydrodynamic vortex oil/grit separator Oil, grease 96% Total suspended solids 85% Metals 81% Nitrogen 79% Phosphorous 70% Media blend membrane filter Fecal coliform 91% Enterococcus 89% E.coli bacteria 83% 9 10. SITE IDENTIFICATION The Bozeman Creek Community Park will be centrally located within the Bozeman Creek Conservation corridor. The corridor is approximately 106 acres in size and is bordered by Kagy Boulevard to the south, Ice Pond Road to the north, Church Avenue to the east and South Wilson Street to the west. More specifically the Community Park will be located within the 400 block of East Lincoln Street east of South Rouse, adjacent to the north boundary of the East Lincoln Street right-away. The proposed Bozeman Creek Community Park would be located on approximately 16,000 square foot parcel of land along the western edge of property that is currently owned by the applicant. Upon approval of this TOPS application this parcel of land would be professionally surveyed and separated from the applicant's estate and conveyed to the City of Bozeman. The applicant has transferred development right (TDR) from the estate recently and dedicated an approximately 4,400 square foot trail easement to the City of Bozeman. At this time the TDR has not been funded and there is no certainty that it will be funded in the near future. The proposed Bozeman Community Park lies adjacent (north) of an active 24 inch storm water outfall. The outfall services approximately 45 acres of urban development. Currently, a constant flow of.1 cubic foot per second or 48 gallons per minute of water flows from the outfall into Bozeman Creek untreated daily. According to an investigation conducted by the City of Bozeman in 2012 this flow originates from an artesian pond located on the Valley View Golf Course property. Drainage tile conveys this flow to the storm water system that connects directly to the outfall adjacent to the project site. This flow is constant, even during the hottest and coldest days of the year. Upon filtration and treatment this source of water could provide a reliable and much needed perennial source of water to Bozeman Creek during low base flow conditions. 11. LONG TERM VALUE FOR RESIDENTS OF BOZEMAN Long term value for the residents of Bozeman would occur through education about impairments to our local streams and rivers and how these impairments can be mitigated and reversed through the use of readily available technology. A hands on approach and community outreach programs will help facilitate this endeavor. This involvement will help promote civic pride and better stewardship of Bozeman Creek so that our children's children and equally important visitors to Bozeman will have an opportunity to enjoy and appreciate our improved community asset far into the future. As a pilot project valuable information will be collected to help replicate this same type project in other stream side neighborhoods throughout the community. Additional long term value and compelling reasons why Bozeman Creek Community Park and Bozeman Creek Water Quality Improvement project should be funded are ➢ 16 streams that flow through Gallatin Valley are listed on MDEQ 303(d) data base. These bodies of water have impairments that affect the ability of these streams to support aquatic life, a cold water fishery or ensure safe primary recreational contact. Pollutants are not geographically bound to one location but collectively concentrate and move downstream. 10 ➢ The new municipal waste water treatment plant is having difficulty complying with the facilities MDEQ waste water treatment discharge permit. The reason is that numerous bodies of water that form the headwaters of the East Gallatin River are severely impaired. ➢ Annual sales tracked by the Chamber of Commerce indicate that thirty seven percent of all recreational sales in Bozeman are for fishing related activities. ➢ Montana Conservation Corp members along with youth from the Montana Outdoor Science School will participate in the construction, monitoring and maintenance of the Park. This is a community project and we would like to include any other group that would like to get involved with this project. 12.0 LIST OF ALL GROUPS/ORGANIZATIONS INVOLVED,LONG AND SHORT TERM COMMITMENT The following organizations have written letters of support for a Bozeman Creek Water Quality Enhancement project ➢ Executive Committee, Bozeman Creek Neighborhood Association ➢ Bozeman Creek Enhancement Committee ➢ Natural Resources Conservation Services ➢ Gallatin Local Water Quality District ➢ Montana Wetlands Legacy ➢ Trout Unlimited Madison-Gallatin Chapter ➢ Montana Fish, Wildlife&Parks ➢ The City of Bozeman, Department of Engineering ➢ Gallatin Valley Land Trust This project could not have progressed to this point without thousands of dollars of In-Kind services provided by the following businesses ➢ Confluence Consulting ➢ HKM/Dowl Engineering ➢ Pure Water Technologies ➢ Bridger Analytical ➢ Rouge Pony Architects ➢ Gossel Appraisal Services ➢ GreenSpace Landscaping ➢ Contech Environmental ➢ Royal Environmental Enterprises Efforts to develop a Bozeman Creek Water Quality Improvement project began approximately 9 years ago. Numerous meetings have been conducted over the years with conservation groups, businesses and government agencies. A tremendous number of hours have been spent collecting and analyzing water quality samples, researching for the best water quality treatment equipment and creating an engineered designed system that would help mitigate impairments to the Creek. 11 All of the different conservation groups, businesses and government agencies that contributed time and money to this project agree collectively that this water quality improvement project should be available for the public to view and learn from. It was further agreed to by these groups that this water quality treatment project should be placed within a Bozeman Creek Community Park to help increase visibility of the project and showcase efforts that are being undertaken to mitigate impairments to Bozeman Creek. Funding will also be sought through the following ➢ Trout Unlimited,Madison and Gallatin Chapters ➢ Fish Wildlife and Parks Future Fisheries ➢ City of Bozeman Capitol Improvement Fund (Storm water Utility) ➢ Community businesses and stake holders 13.0 DESCRIPTION OF ANTICIPATED MAINTENANCE REQUIREMENTS The Bozeman Creek Community Park itself will require very little maintenance at tax payer's expense. Maintenance of natural areas of the Park will be maintained by the applicant and the applicants heirs for as long as the applicant resides at 425 East Lincoln Street. The Bozeman Creek water Quality Improvement Project located within the Bozeman Creek Community Park will require funding for monthly maintenance and environmental monitoring in accordance with the enclosed (Sampling and Analysis (SAP Plan). The City of Bozeman, Gallatin Local Water Quality District and Montana Department of Environmental Quality will be asked to assist with project oversight. The City of Bozeman Capital Improvement program namely the newly created storm water utility will be asked to assist with costs associated with labatory analysis of collected water quality samples, data analysis and bi-annual reporting. Monthly maintenance will include trash removal and disposal, which the applicant is willing to perform at his own expense. Periodic sediment removal, dependant on loading rates, lab analysis and proper disposal to a Resource Recovery Act(RCRA facility), Logan Landfill, should be paid for by the City of Bozeman. Storm water filter replacement will be the responsibility of the City of Bozeman. Depending on loading rates filter removal, disposal and replacement will occur every 5 to 7 years. 14.0 MITIGATION NEEDS ON THE PROPOSED PARKLAND PROPERTY The proposed Parkland property will need to be subdivided from the applicant's estate. This should not present a problem considering the property was once the preliminary platted 3 lot Minor Suiter Subdivision when purchased by the applicant in 1999. 12
