These items should appear on the erosion and sediment control map required. *Items in red/pink are required to be filled in. iii. For the following sections, select the best management practices from the list that will be used and show location(s) on the map. If a practice will be used that is not on the list, describe the practice in “Other” section. If NA was selected for any of the items, explain why in the “Not applicable” section. 1. Inlet Protection – Inlets receiving site runoff require best management practices (BMPs) that filter stormwater before flowing into underground infrastructure. 2. Outlet Protection – Outlets receiving site runoff require BMPs that prevent erosion. 3. Stabilization & Erosion Control – Disturbed areas require BMPs that prevent erosion of barren ground. 4. Perimeter Control – Project boundaries require BMPs that contain stormwater flowing from disturbed areas. 5. Sediment Control – Sediment and stockpiles require containment and BMPs that prevent erosion and displacement of loose material. ---PAGE BREAK--- P a g e I 5 6. Stockpile Control – Sediment and stockpiles require containment and BMPs that prevent erosion and displacement of loose material. 7. Tracking Control – Travel and exit points require BMPs that prevent tracking of debris off-site onto the right-of-way and meet the City of Kalispell’s Standards for Design and Construction. 8. Waste, Spill, & General Pollution Prevention – Construction activities create waste and pollution and require BMPs to prevent contamination of local waterways. 9. Wind Erosion Control – Wind can erode barren land and stockpiles and requires BMPs to reduce erosion. 10. Run-on Protection – Sites below slopes may have issues with run on and require BMPs to prevent run on from eroding the site. 11. Permanent Erosion Control – Disturbed land related to the project activities require BMPs before final occupancy of structures to prevent erosion. iv. Project Schedule – Enter the estimated start, completion, and final stabilization dates. v. List water bodies within 200 feet of the project vi.

Applications are not reviewed until the online submission, payment, and the erosion and sediment control map are received. ---PAGE BREAK--- P a g e I 6 Single Family Residential Recommendations WHY: Kalispell’s stormwater system typically runs untreated to our local lakes, rivers, and streams. When pollutants and trash are on the street or flow offsite during rain events, they flow down the curb, into storm drains, and discharge into and pollute local water bodies. WHAT: The intent of the permit application is to review the plan on how all pollutants, including sediment, will be kept onsite during construction at the project site. HOW: Below are the recommended best management practices (BMPs) for *most single-family residential builds. *Items may vary depending on existing site conditions. 1. Inlet Protection a. If there are storm drains/inlets near the project, it is highly recommended to protect the inlet (i.e. witches hat or similar product). Use the online map to find stormwater inlets: http://kalispell.com/469/Map 2. Stabilization & Erosion Control a. Preservation of existing vegetation i. This item is recommended, when possible. If maintained, existing vegetation is cheap, easy, and effective at filtering and preventing sediment-laden stormwater from leaving the site. 3. Perimeter Control a. Vegetated buffer i. Keeping a vegetated buffer around the outside of the site can be very helpful to reduce sediment moving offsite when it is maintained. Once the site is ready for final vegetation/sod, the existing vegetation can be removed. b. Silt fence/fiber roll i. If there is no vegetation on your site, we have seen very few, if any, sites prevent sediment from leaving the site without some other type of perimeter control. 4. Sediment Control a. Street sweeping i. If dirt is tracked off the site, it needs to be removed from the streets. Street sweeping can be utilized to do this. 5. Stockpile Control a. Water b. Cover/Tarp c. While these items can be as needed, please select which will be used if they are indeed needed. 6. Tracking Control a. Stabilized construction entrance/exit (i.e. tracking pad) i. This item is highly recommended. For most residential builds, we see angular rock placed where the proposed driveway will be to provide some area to get dirt/mud off the tires of vehicles entering and exiting the project. Installing the concrete driveway ASAP is also a good method to help reduce debris tracking offsite. 7. Waste, Spill & General Pollution Prevention a. Concrete washout area i. Having a designated concrete washout area prevents washout from occurring throughout the site and reduces the potential for vehicles to drive through it. ii. If concrete washout will occur offsite, please indicate. b. Saw cutting and grinding controls i. If water, vacuum, or any other method will be used to reduce pollution from cutting and grinding, you can take credit for that. c. Enclosed waste collection ---PAGE BREAK--- P a g e I 7 i. Most builds utilize some sort of trash container/trailer onsite. If you are not using this, please explain why. d. Sanitary waste facilities i. Most builds utilize porta-potties. If you do not need this, please explain why. e. Spill prevention and control measures i. It is highly recommended to have some sort of plan/basic materials (absorbent material) for a spill. If something did spill (i.e. hydraulic fluid, concrete, paint, etc.), can you contain, clean up, and dispose of it properly? If so, you can take credit for this. f. Covered storage of chemicals, paint, petroleum, fertilizer, and pesticides i. While there might not be many of these products onsite, paint is common at some point. If these types of materials can be stored under cover (i.e. garage, trailer), you can take credit for this. 8. Wind Erosion Control a. Watering i. If needed, can you water to keep dust down? 9. Run-on Protection a. Are there any steep slopes that run onto this project/site? If so, how will the extra stormwater running from the slope onto the site be handled? 10. Permanent Erosion Control a. Landscaping/Vegetation i. Once construction is complete, will landscaping, seeding, or sod be utilized for permanent erosion control? b. Seeding c. Sod 11. List water bodies within 200’ a. Use the online map to identify: http://kalispell.com/469/Map 12. Discharge to an Impaired Waterbody a. This question refers to where the runoff eventually drains regardless of distance. b. Our stormwater website has an interactive map (http://kalispell.com/469/Map) showing drainage basins and stormwater infrastructure. Information on local water quality impairments can be found on our website and on DEQ’s site 13. List storm conveyance system within 100’ a. Use the online map to identify: http://kalispell.com/469/Map 14. Agreements (all items are required and require initials) a. Install applicable best management practices (BMPs) prior to the start of land disturbing activities. b. Keep this permit posted on-site and updated to reflect current site conditions. (A digital copy is fine.) c. Inspect & maintain all control measures at the end of EACH workday. d. Contain & dispose of all pollutants generated by local, state, & federal regulations. e. Maintain a spill kit on-site, which includes, at a minimum, absorbent material, cleanup tools, and covered waste container. 15. Responsible Party Signature a. "By signing the Permit, the Responsible Party shall assume full responsibility for the contents of the Permit and prevent pollutants from leaving the site - enter full name & date". ---PAGE BREAK--- P a g e I 8 Once the recommended items above have been selected, the required erosion and sediment control map will need to include the approximate location of the selected items. Items that will need to be added to the map, if selected, include: - Project boundary, north arrow & adjacent streets - Directions of stormwater run-on and runoff - Public & Private stormwater infrastructure on or adjacent to site - Receiving waters on or adjacent to the site - Material storage and spoil area(s) / Stockpile location - Equipment staging area(s) - All best management practices (BMPs) selected on the application o Inlets and indication of inlet protection o Perimeter control o Any locations where silt fence or straw wattles / fiber roll will be used o Tracking pad o Concrete washout o Enclosed waste collection/trash o Sanitary waste facilities/porta-potty o Any other selected BMPs that have a set location
