The WQCD’s General Permit for Stormwater Discharges from Construction Activities allows for dewatering of groundwater and stormwater to the ground surface to allow for infiltration on the site. No groundwater from construction dewatering will be discharged as surface runoff or to surface waters on the site. It is not anticipated that dewatering activities will be required during this project. However, if dewatering becomes necessary, groundwater and/or stormwater may be pumped from excavations or trenches to the ground surface on the site for infiltration or evaporation. The location of pumping and deposition of the groundwater or stormwater will be marked on the site plan prior to the start of pumping activities. If it becomes necessary to pump groundwater off site or into a waterway or storm sewer, then a groundwater discharge permit must be obtained from the State prior to engaging such activities. The following table lists remaining non-stormwater discharge activities and the associated BMPs (structural and non-structural) used to minimize and eliminate discharge of pollutants. Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 10 Note to SWMP Administrator: The populated list below will serve as an initial guidance to non-stormwater discharge activities. The list also provides BMPs (structural and non- structural) for the associated activities. However, it is the responsibility of the SWMP Administrator to continually update and monitor the inventory list and ensure that each activity has a BMP installed to eliminate any discharge possibility. Non-Stormwater Discharge Activity Associated BMPs Vehicle Equipment Maintenance and Fueling • Designate a specific location for vehicle maintenance. • Provide proper containment around the perimeter of maintenance area. • Designate a specific location for vehicle fueling. • All fuel to be used and stored on site shall be placed in secondary containment. • Spill kits should be available at maintenance and fueling areas. • Areas shall be inspected thoroughly preferably at more frequent intervals than regular stormwater inspections. • Educate all personnel on proper fueling and maintenance practices to avoid any discharge of pollutants. • Educate personnel on spill response techniques. • Identify maintenance and fueling location(s) on the SWMP site map.

Material Storage Please note that vehicle fueling/washing, concrete waste management, construction dewatering, sanitary/septic waste management are all addressed in Section 2.1.4. of this SWMP. Solid Waste Management Solid waste management procedures and practices are designed to prevent or reduce the discharge of pollutants to stormwater from solid or construction waste by providing designated waste collection areas and containers, arranging for regular disposal, and training employees and subcontractors. All waste materials will be collected and stored in a securely lidded dumpster. All trash and construction debris from the site will be deposited in the dumpster. The dumpster shall meet all local, State, and Federal solid waste management regulations. The dumpster will be emptied a minimum of twice per week by a qualified and licensed solid waste management contractor, and will be hauled to an approved dumping site. No construction waste materials will be buried on the project site. All personnel will be instructed regarding the correct procedure for waste disposal. Notices stating these practices shall be posted on the job site. The SWMP Administrator will ensure these practices are being followed. Hazardous Materials Management Prevent or reduce the discharge of pollutants to stormwater from hazardous waste through proper material use, waste disposal, and training of employees and subcontractors. The responsible parties shall manage Hazardous Materials on site by implementing the following five BMPs to Hazardous Materials Management: • Material Use • Waste Recycling Disposal • Disposal Procedures specified by local, State or Federal regulations • Education Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 14 • Inspection and Maintenance Liquid Waste Management Liquid waste management includes procedures and practices to prevent discharge of pollutants to the storm drain system or to watercourses as a result of the creation, collection, and disposal of non-hazardous liquid wastes. The responsible parties shall manage Liquid Waste on site by implementing the following five BMPs to Liquid Waste Management: • Education • Containment • Capture • Disposal • Inspection and Maintenance Material Storage The purpose is to prevent, reduce, or eliminate the discharge of pollutants from material storage to the stormwater system or watercourses by minimizing the storage of hazardous materials on- site, storing materials in a designated area, installing secondary containment, conducting regular inspections, and training employees and subcontractors. The site will designate a specific location where the Material Storage Area or areas will be located. The following BMPs will be implemented at each Material Storage location on site: • Designate entrance and exit points. • Install vehicle tracking control at entry and exit point(s) • Appropriate perimeter BMPs need to be installed. All materials must be properly and tightly sealed in original containers with manufacturer’s label for identification. Damaged or illegible labels should be replaced immediately. Materials must be stored at a minimum on pallets, but preferably in secondary containment to prevent any leaks or spills to exit into the ground or come into contact with stormwater. Materials preferably will be stored under a cover or tightly secured tarp to prevent contact with stormwater. The Material Storage Area must be inspected at a minimum during regularly scheduled stormwater inspections. Inspector should pay close attention to any signs of leaks or spills. Spill kits should be present at the Material Storage Area. All on site workers shall be trained and educated in proper material handling and storage prior to conducting any work with materials. Material Safety Data Sheets (MSDS) sheets should be made available for all materials stored on site. Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 15 If more than 1,320 gallons of petroleum products in 55 gallon drums or larger containers will be stored on-site overnight, then a site specific Spill Prevention, Control and Countermeasure plan, stamped by a certified engineer is required. Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 16 3.0 BEST MANAGEMENT PRACTICES 3.1.1 Purpose Section 3.0 of this Stormwater Management Plan will identify the Best Management Practices associated with the project. This section will call out phasing of the BMPs that will coincide with the sequencing for major construction activities on the site. A section of technical drawings and installation specifications of each BMP will also be included. Note to SWMP Administrator: It is the responsibility of the SWMP Administrator to ensure all BMPs called out in this plan are adequate for the current conditions on site. It is the responsibility of the SWMP Administrator to make necessary changes to the SWMP concerning BMPs, when BMPs are replaced or new BMPs are needed on site due to changing site conditions in order to keep the site in compliance with the stormwater permit. 3.1.2 Description and Maintenance Structural and non-structural BMPs shall be implemented on site to help prevent erosion and sedimentation. Below is a description of each on site BMPs purpose, limitations, installation, inspection, and maintenance requirements. Temporary and permanent erosion sediment controls shall be used to provide soil stabilization and divert stormwater runoff for both pre- and post-construction conditions. Structural controls, such as fugitive dust mitigation and a concrete washout area will be used to limit off-site tracking of sediment during construction onto Lincoln Ave. All BMPs used on site must be maintained in effective operating condition and in accordance with good engineering, hydrologic, and pollution control practices. During routine inspections, the site BMPs must be inspected for their effective operating condition. If a BMP or several BMPs are found not to be operating effectively, maintenance to those BMPs must be initiated immediately. Replacement of failed BMPs must occur immediately upon findings of noncompliance and failed performance of any particular BMP on the project site. New BMPs that are installed or replaced will result in a need to properly update the SWMP and the site map to show the changes. Note: CONTRACTOR SHALL TAKE ALL NECESSARY MEASURES DURING UTILITY INSTALLATION TO ENSURE THAT SEDIMENT IS NOT RELEASED FROM THE SITE. TO INCLUDE, BUT NOT LIMITIED TO: UTILITY TRENCHES EXIST ONLY FOR INSTALLATION OF CORRESPONDING UTILITIES. SPOILS SHALL BE PLACED ON THE UPHILL SLOPE SIDE OF THE TRENCH. Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 17 3.1.3 Water Quality Control Plan Several temporary sedimentation and erosion control devices will be used during construction to reduce the amount of sediment transport from and across the site. During Phase 1, silt fence will be installed along the perimeter of the site, wattles will be installed up slope of the silt fence along the river, vehicle tracking control, stabilized staging area, concrete washout and the inlet protection for the rain garden in Lincoln Avenue just west of the project site. This will protect the Cache La Poudre from any sediment release from the construction site. While construction is underway the BMP’s in place will work in conjunction such that if one fails there will be redundant measures to prevent any sediment from reaching the river. During Phase 2, a treatment train of redundant BMP’s are in place starting with rock check dams, then to inlet protections, running into the sediment basin, wattles up slope from the river, and silt fence around the disturbed area of the site. In Phase 3 the treatment train of redundant BMP’s starts in the north with rock check dams and runs south past inlet protections, towards the rain garden which is surrounded by wattles. Silt fence is also in place along the outside of the site disturbed area with wattles up slope from the river. For the Phase 4 treatment train, the site will be seeded and mulched in all landscaped areas, and sediment erosion will be limited and mitigated by the detention pond and rain gardens, and the outfall to the river will be controlled by the pond outlet structure. The detention pond will serve as a sediment basin during overlot grading and until Phase 3. The Inlets noted on the plan sheets along Lincoln Ave impacted by the project will be protected with BMP’s through Pase2 and 3 to mitigate sediment pollution into existing storm systems. Once the Infrastructure and hardscape are installed in Phase 3 the sediment basin will converted over to the detention pond and rain garden. The rain garden will be protected by wattles until the site is completely stabilized in Phase 4. In Phase 4, seed and mulch will be installed to stabilize slopes and allow vegetation after construction is completed. Permanent stormwater quality features incorporated into this development include one extended detention basin and one rain garden. The rain garden is located in the bottom of the extended detention basin. The detention facility is designed to treat the water quality capture volume in the Rain Garden. The Rain Garden is designed to drain within 12 hours. 3.1.4 Phasing and Sequencing The following table lists the phases of construction for the Project and the implementation of structural and non-structural BMPs associated with the particular phase of construction. The phases are defined as follows: • Phase 1: Initial / Pre-Overlot Grading phase • Phase 2: Overlot Grading and Vertical Construction Phase • Phase 3: Infrastructure Phase, paving, curb and gutter • Phase 4: Final Stabilization and Permanent BMPs Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 18 Sediment/Erosion control BMP Phase of Construction Description* Silt Fence 1-3 A woven geotextile fabric attached to wooden posts and trenched into the ground. Its purpose includes intercepting sheet flow runoff from disturbed areas. Vehicle Tracking Control 1-3 Provides stabilized construction site access where vehicles exit the site onto paved public roads. An effective vehicle tracking control helps remove sediment (mud or dirt) from vehicles, reducing tracking on the paved surface. Stabilized Staging Area 1-3 A designated area where construction equipment and vehicles, stockpiles, waste bins, and other construction related materials are stored. Concrete Washout Area 2-3 Concrete waste management involves designating and properly managing a specific area of the construction site as a concrete washout area. A concrete washout area is one of the following: excavation of a pit in the ground, use of an above ground storage area, or use of prefabricated haul away concrete washout containers. Inlet Protection 2-3 Permeable barriers installed around an inlet to filter runoff and remove sediment prior to entering a storm drain inlet. Can be constructed from rock socks, sediment control logs, silt fence, block and rock socks, or other materials approved by the local jurisdiction. Seed & Mulch 2-4 Seeding includes preparing a seedbed selection of an appropriate seed mixture, proper planting techniques and protection of the seeded area with mulch. Seeding is used to stabilize areas that will be inactive for an extended period. Mulch consists of evenly applying straw, hay, shredded wood mulch, rock, bark or compost to disturbed soils and securing the mulch by crimping, tackifiers, netting or other measures. Mulch is used to help reduce erosion by protecting bare soil from rainfall impact, increasing infiltration, and reducing runoff. Stock Pile 1-3 Stockpiles should be located away from all drainage systems. If practical use undisturbed areas. The stockpile surface shall be stabilized with surface roughening, temporary seeding and mulching, erosion control blankets, or soil binders. Seeding and mulching will be used to prevent wind erosion. When the stockpile is no longer needed, dispose of the excess materials and revegetate area. Curbside Checkdam Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 19 4.0 FINAL STABILIZATION 4.1.1 Purpose Section 4.0 of the SWMP details how the site will achieve final stabilization/re-vegetation for the project. It is required by the permit for Stormwater Discharges associated with Construction Activities that final stabilization will be achieved when all ground disturbing activities are completed and a uniform vegetative cover has been established with an individual plant density of at least 70% pre-disturbance level, or equivalent permanent, physical erosion reduction methods have been employed. Note to SWMP Administrator: The removal of temporary BMPs must not take place until the site has completed ground disturbing activities and a uniform vegetative cover has been established in the designated re-vegetation areas with the individual plant density of 70% pre-disturbance levels. Note: Landscaping shall be installed per the landscape plan. Site Specific Re-Vegetation Plan The re-vegetation plan for the project consists of landscaping and seeding and mulching (if necessary) upon completion of all construction activities. All disturbed areas not covered by gravel paving or the building pad shall be seeded & mulched or landscaped per the enclosed erosion control plan and accompanying notes. Areas in close proximity to Natural Areas will use a Native Seed Mix. Refer to following notes for proper native seed area installation: 1. Prepare soil as necessary and appropriate for native seed mix species through aeration and addition of amendments, then seed in two directions to distribute seed evenly over entire area. 2. If changes are to be made to seed mix based on site conditions then approval must be provided by city environmental planner. 3. Appropriate native seeding equipment will be used (standard turf seeding equipment or agriculture equipment shall not be used). 4. Drill seed application recommended per specified application rate to no more than 1/2 inch depth. For broadcast seeding instead of drill seeding method double specified application rate. Refer to native seed mix table for species, Percentages and application rates. 5. Treat native seed mix area prior to installation of seed with appropriate herbicide to proactively mitigate herbaceous weed species growth during establishment period then after appropriate time period apply native seed as called for On approved plans. 6. After seeding the area shall be covered with crimped straw or other appropriate methods and provided temporary irrigation until seed is established. 7. Contractor shall monitor seeded area for proper irrigation, erosion control, germination and reseeding as needed to establish cover. Spirit at the River Hotel, SWMP Spirit at the River Hotel 017-0150 20 8. The approved seed mix area is intended to be maintained in a natural like landscape aesthetic. If and when mowing occurs in native grass seed mix areas do not mow lower than 6 to 8 inches in height to avoid inhibiting native plant growth. 9. Native seed area will be considered established when seventy percent total cover is reached with no larger than one foot square bare spots and/or until deemed established by city planning services The project will utilize sod, ornamental grasses, native plantings, rock mulch, trees, and shrubs as a final stabilization method of all disturbed areas. Note to SWMP Administrator: It is the responsibility of the SWMP Administrator to oversee seeding operations to ensure proper application for expected growth. 4.1.2 Post-Construction BMPs Post Construction BMPs or permanent structures that will remain on site include permanent landscaping. An Operating and Maintenance manual may be developed in accordance to the CDPHE requirements and can thus be referenced for future maintenance procedures. Phasing of the stabilization plan, changes in inspection frequency, and closing of the CDPS permit shall be documented.
