STORMWATER POLLUTION PREVENTION PLAN - CONSTRUCTION 1. Hydrologic Unit Code 05120201090030 2. Receiving Waters Discharge is to a municipal separate storm sewer. Ultimate discharge is to Cool Creek – Grassy Branch and Little Cool Creek. 3. Peak Discharge – Post Construction (10-year) The proposed site is a 0.83-acre area. (See Attachment 4 for proposed drainage area map). Due to the limited area for detention on the site, release rates based on Carmel’s redevelopment standards were used. This calls for the 10-year and 100-year storms of the proposed site to be released at the rates of the 2-year and 10-year storms of the existing site. Detention was sized to accommodate both onsite and offsite flow while accounting for direct discharge. See Table 1 for the drainage summary of the site. Table 1: Site Drainage Summary Onsite Offsite Drainage Area (ac) 0.83 0.24 2-yr 10-yr 100-yr Existing Onsite Flow 3.15 4.16 6.21 Existing Offsite Flow - 1.14 1.70 Total Existing Discharge - 5.30 7.90 Allowable Discharge - Onsite (cfs) - 3.15 4.16 Proposed Direct Discharge of Onsite Flow (cfs) 0.79 1.17 Carmel Clay Community Building Project No. 1963-1025-90 5 Detention Outflow of Onsite Flow (cfs) 1.47 2.03 Total Onsite Discharge (cfs) 2.26 3.20 Proposed Direct Discharge of Onsite and Offsite Flow (cfs) 1.04 1.55 Detention Outflow of Onsite and Offsite Flow (cfs) 1.48 4.09 Total Onsite and Offsite Discharge (cfs) 2.52 5.64 Storage Volume (cuft) 595 834 4. Stormwater Discharge Drainage from the building roof, west side of the site and south side of the site will be collected and routed through an underground detention basin located under the service drive on the south side of the building. Areas to the east of the building will direct discharge to Veterans Way and be picked up by the existing street drainage system. Area to the north of the building will be picked up by a drainage trench with an underdrain and discharged to the storm system in Veterans Way. Areas draining to the detention basin are made up of concrete, roof, mulched plantings, turf and decorative stone mulch. 5. Stormwater Discharge - Groundwater No stormwater will be directly discharged to groundwater. 6. Soils Map See Attachment X. 7. Potential Pollutant Sources - Construction Pollutants that may be generated during construction include oil, grease, antifreeze, brake fluid, brake dust, rubber, gasoline, diesel, metals, grit, fuel and oil leakage from equipment and vehicles, debris from materials storage, and sediment runoff. 8. Stormwater Quality Measures See Sheets SD3.5, SD4.1 and SD6.1 Attachment 2 for location, dimensions, and construction details of temporary and permanent stormwater quality measures. Carmel Clay Community Building Project No. 1963-1025-90 6 Temporary A. Construction entrance shall be provided from Veterans Way in the southern portion of the project site and constructed per the detail on Sheet SD3.5 in Attachment 2. Any sediment or debris tracked out of the project area must be cleaned up the same day it occurs as noted on the plans. B. Storm sewer inlet protection will be provided as indicated on Sheet SD3.5 and Detail 1/ Sheet SD3.6 in Attachment 2. C. Perimeter protection will provide runoff control during construction as indicated on Sheet SD3.5 and Detail 2/ Sheet SD3.6 in Attachment 2. Permanent A. Detention is provided by a 48-inch diameter concrete pipe located on the south side of the property. The piped storm system is designed to carry the 10 -year storm of both the onsite flow and offsite flow with the Hydraulic Grade Line of 100-year storm remaining below rim elevations. The water quality unit will treat approximately 0.18 acres of offsite flow to offset the approximately 0.19 acres of onsite direct discharge. Water quality for the site consists an Aqua Swirl XCelerator Model XC-3 (off-line) just prior to the detention basin with a maximum treatment flow of 1.13 cfs. Monitoring and Maintenance A. On-site monitoring will be performed by the Contractor. The Contractor shall monitor the following measures, as well as any other additional measures installed on site: perimeter protection, inlet protection, and cleanup of sediment tracked offsite. Maintenance shall include keeping an up-to-date record onsite of any alterations to the Stormwater Pollution Prevention Plan. B. The contractor has full responsibility of inspecting the erosion control measures daily. The Contractor shall designate an individual responsible for installation, inspection, and maintenance of these measures. At a minimum, practices need to be inspected weekly, within 24 hours after each storm event over ½ inch and daily during prolonged storm events. Inspection of practices during a storm event is advantageous because the inspector can easily identify where measures need to be repaired or replaced. Failing practices shall be repaired or replaced immediately. C. The owner shall be responsible for all maintenance and costs associated with the maintenance of the BMP (Aqua Swirl XCelerator Model XC-3) for this development. 1. The City of Carmel has a right to enter the property to inspect and maintain the BMP for this development as necessary. 2. Annual inspection reports are to be submitted to the Carmel Engineering Department. The first report is due one year after construction is completed, with subsequent reports each year thereafter in the same month of the initial report. If there are any deficiencies found during the inspection, these s hould be Carmel Clay Community Building Project No. 1963-1025-90 7 addressed. If the inspection report is not received within the month it is due, if there are deficiencies which were not included in the report, or if any deficiencies included in the report are not addressed in a timely manner, the BMP owner face s enforcement action from the City. 9. General Construction Sequence A. Construction Routes, Equipment Parking Areas –All ingress and egress points shall be stabilized with a gravel construction entrance. B. Perimeter Controls and Inlet Protection – Install principal barriers including silt sock and inlet protection of existing inlets after construction site is assessed and before land disturbance begins. C. Building Construction – Proceed with construction of new building. D. Pavement Removals, Grading, and Inlet Installation – Proceed with removal of existing pavement, followed by earthwork and installation of new inlets/BMP’s where required. E. Temporary Stabilization – If needed, apply temporary stabilization measures immediately on all disturbed areas where work is delayed or completed for 7 days or more. Temporary mulching is also required over the winter season per Indiana Stormwater Quality Manual. F. Paving – Permanently stabilize areas with pavement as shown on plans. G. Permanent Turf/Mulched Planting Beds – Install vegetative measures as shown on plans after adjacent building and hardscape construction is completed. H. Construction Close Out – Remove remaining temporary measures (perimeter protection – fiber roll, construction entrance, inlet protection) and restore affected areas as needed. Temporary measures can be removed once 70% density of permanent vegetation is established or another stabilization measure such as pavement is in place. I. Final Site Inspection - A final site inspection will take place to assure that all requirements of the SWPPP, construction plans, and supporting documents have been fulfilled. 10. Proposed Stockpiles, Borrow and Disposal Sites During excavation soils will be hauled offsite, building framing will be stored in side the building footprint. The jobsite trailer we will be in northeast corner of the site. No lay down areas are anticipated outside site perimeters. No onsite construction parking will be allowed. 11. Stabilization Measures Temporary A. Temporary mulching will be installed on any cleared areas that will be undisturbed for 7 days or more. In the case that land is disturbed outside of appropriate seasonal planting periods, temporary mulching must be installed to provide winter stabilizatio n until such time as a permanent stabilization measure can be implemented. Carmel Clay Community Building Project No. 1963-1025-90 8 Permanent A. Most areas will be permanently stabilized with pavement. The remaining areas will be stabilized with turf sod, mulch plantings, and filter fabric/ decorative stone mu lch as indicated on Sheets SD2.3 and SD4.1 in Attachment 2. 12. Erosion and Sediment Control Specifications for Individual Lots Not applicable to this project. 13. Material Handling, Storage, and Spill Prevention Prior to the commencement of construction, the Contractor will be required to submit a material handling and spill prevention plan. The Contractor is responsible for prevention and cleanup of any of these sources. The Contractor is urged to protect the s ite and maintain a single storage on site. It is the responsibility of the contractor to handle the pollutant properly and respond to a spill. Materials should be stored in a manner that prevents or minimizes the chance that a spill will reach soils, groundwater or surface water. If a spill does occur, then the spill must be contained immediately utilizing appropriate response techniques including diking and absorbents. Clean up of the spill should occur as soon as possible once the spill is stabilized and contained. Spills shall be cleaned up using acceptable methods such as, absorbents on impervious surfaces or removal of contaminated soils. All spills that occur near an inlet to the stormwater conveyance system must have “curbing” implemented immediately. “Curbing” is the use of a barrier (absorbent material) which prevents the spill from contacting the stormwater conveyance system or stormwater runoff. In all cases cleanup standards must adhere to local, state and federal requirements. Failu re to clean up any spill is a violation of the Indiana State Spill Rule (327 IAC 2 -6.1), which is enforced by the Indiana Department of Environmental Management (IDEM). Certain spills must be reported to the local response agency, Local Emergency Planning Committee and/or IDEM. Initial calls should be made to the 911 system if the spill exceeds reportable quantities or is a threat to public safety. The 911 system will typically notify the Fire Department. IDEM (1-888-233-7745) can typically assist with information on clean-up operations or clean up contractors. 14.
