All the City parking facilities are located in the downtown area. The City parking facilities function similarly regarding stormwater, so all five sites are included in this FSWPPP. Specifically, all the City parking lot facilities are comprised of stabalized parking surfaces that drains stormwater to the City’s stormdrain infrastrucutre. The Parking Garage includes two pre-treatment technologies: a sand/oil separator and a hydrodynamic separator. The Parking Garage has two drainage basins: a. Drainage basin #1: 0.75 acres of 100% impervious surface drains from the upper parking level and conveys runoff to a hydrodynamic separator for pretreatment before discharging into stormdrain infrastructure. b. Drainage basin #2: 0.25 acres of 100% impervious surface drains stormwater off the retail suits rooftops which are located on the western and northern faces of the Facility. This stormwater runoff is pre-treated with a sand/oil separator before flowing into the sanitary sewer system. Public Parking Lots #1,2,3, and 4, respectively, have the following drainage basins: a. Drainage basin (Parking lot #1): 0.37 acres of 100% impervious parking space b. Drainage basin (Parking lot #2): 0.25 acres of 100% impervious parking space. c. Drainage basin (Parking lot #3): 0.55 acres of 90% impervious parking space. d. Drainage basin (Parking lot #4): 0.40 acres of 100% impervious parking space. 4.0 WATERBODY Stormwater runoff from the Parking Garage receives pretreatment in a hydrodynamic separator before discharging to Bozeman Creek at outfall ID: OF.F04.00441. Stormwater from all four Public Parking Lots discharge to Bozeman creek without pretreatment. The Montana Department of Environmental Quality classifies Bozeman Creek as a 303(d) listed impaired waterbody because it does not fully support aquatic life and primary contact/recreation beneficial uses. Bozeman Creek’s impairments include: Alterations in stream-side (littoral) vegetative cover, Chlorophyll-a, E. coli, total nitrogen, and sedimentation and siltation.

Locate spill kit and put on PPE. If necessary, deploy the Public Works spill response vehicle. Control spill by stopping or securing the source. Protect all storm drain inlets near the spill using absorbent booms or inlet barrier. Identify spilled material. Clean spill using appropriate absorbents or other methods. Never wash spills down the drain! Place spill material and absorbents in secure containers. Consult with Stormwater Team Leader and the Saftey Data Sheets (SDS) for spill and waste disposal procedures. Dispose of spilled material and the absorbent in compliance with state and federal regulations. Consult with Stormwater Team Leader for appropriate reporting procedures. 8.2 Large and Continuous Spills: Typically, the major dimension is greater than 6’, continuous flow, and cannot be contained, cleaned, and eliminated using onsite personnel. Leave the area and notify Emergency Responders (911). Give the operator the spill location, chemical name, and approximate amount. If safe, protect nearby storm drain inlets using absorbent booms or inlet barrier. Provide SDS information for the spilled chemical to emergency responders. Advise responders of any absorbents, containers, or spill control equipment that is available. Consult with Stormwater Team Leader for appropriate reporting procedures. 8.3 Spill Reporting Report all chemical spills, regardless of size, to a Stormwater Program Coordinator. 9.0 TRAINING Staff receives training related to this Facility per the requirements within the City’s MS4 Permit and maintains training documentation in the SWMP. 10.0 INSPECTIONS Stormwater staff completes an annual facility inspection and provides results to the Program Coordinator who determines compliance with the City’s Facility Minimum Standards listed in the SWMP.

Center, Registered Agent Bridger Creek Subdivision Community Association, Inc. PO Box 4592 Bozeman, MT 59772 RE: Bridger Creek Subdivision High-Priority Stormwater Facility Inspection Kim Center, Bridger Creek Subdivision Community Association is responsible for the maintenance of a stormwater facility the City of Bozeman has deemed as a high-priority due to its size and discharge location. Stormwater facilities are engineered systems designed to capture, store, infiltrate, and release urban runoff to local waterways. Unmaintained stormwater facilities pose a risk to residents, property, and the environment by increasing the chance of urban flooding and waterway pollution. As such, the City completes annual inspections of high-priority facilities. On September 1st, 2021, Stormwater Division personnel completed an inspection of the Bridger Creek Subdivision Community Association facility and have compiled the following information for your review: 1. Bridger Creek Stormwater Facility Map 2. Stormwater Facility Inspection Report, including findings and maintenance items 3. Stormwater Facility Maintenance Guide In summary, we have identified the following issues during the inspection: 1. The stormwater facility contains sediment, overgrown dead and dying vegetation, and excessive live vegetation which may prevent stormwater from accessing the outlet structure. 2. Stormwater capacity may be reduced over time, and potentially negatively affect detention time (increasing flood risk and erosion) and downstream water quality of the East Gallatin River. The City asks that Bridger Creek Subdivision Community Association submit a plan for maintenance of these issues. I am available to answer questions regarding this letter and the attached information and can be reached at rsmith@bozeman.net or 406-582-2937.

DocuSign Envelope ID: 5EB6CD9B-9275-4C9C-BBB3-D27F70A49913 1 - Version 5 September 7, 2021 Stormwater Facility Maintenance Guide What is a stormwater facility? A stormwater facility is an engineered depression constructed to capture and treat polluted stormwater flowing from roads, parking lots, and driveways. Maintenance of stormwater facilities is necessary to ensure their proper function, reducing negative impacts on local waterways and flooding. What is the benefit of a stormwater facility? A stormwater facility:  Controls the rate of stormwater runoff flowing into streams, reducing flooding and erosion.  Removes stormwater pollutants, such as sediment, fertilizers, pet waste, metals, and oils, protecting the public and the environment. Who is responsible for stormwater facility maintenance? Typically, the City requires developers to create and implement a stormwater facility maintenance plan when constructing a subdivision or property. Home Owner Associations (HOAs) assume responsibility when the subdivision changes ownership, and the developer is no longer involved. How do I maintain a stormwater facility? The City recommends HOAs complete the following:  Compile relevant documents, such as infrastructure plans, maintenance plans, and contracts.  Complete a facility inventory, documenting facility location, and condition information.  Develop a comprehensive plan, including budget, inspection frequency, and a record-keeping process. Assistance from a qualified professional may be helpful. Important stormwater facility characteristics to consider include:  Capacity: Excess vegetation and sediment reduces capacity and affects performance.  Soil infiltration: Compaction and accumulated sediment reduce infiltration rates, resulting in stagnant, standing water that can breed mosquitos and algae.  Vegetation height: 6” or taller reduces flow velocity and provides water treatment. Images 2 through 5 show the results of inadequate stormwater facility maintenance.

The City recommends the following maintenance strategy: 1. Routine Maintenance Activities (1-3 Months)  Designate “no-cut zones” in the bottom of the facility  Remove trash, leaves, grass clippings, and debris  Establish a chemical-free zone in and around the facility  Inspect for uniform ponding, and that water disappears three days after rain events 2. Annual Maintenance Activities (Annually)  Cut vegetation to 6” in fall, remove clippings  Re-establish vegetation on eroded and barren areas  Remove excess sediment buildup  Update maintenance plan and inspection log 3. Long-Term Maintenance Activities (10-15 Years)  Consult a qualified professional to inspect and return the facility back to its initial design and capacity  Dredge facility if sediment buildup is greater than 6”  Re-establish vegetation along the facility’s banks and bottom Contact Information It is important HOAs maintain their stormwater facilitys to ensure Bozeman continues to be “The Most Livable Place”. Please contact the Stormwater Division for more information or to schedule a voluntary inspection.
