HomeMy WebLinkAbout_BMP - O&M Manual-Final RecordedA. A Water Quality BMP is a “Best Management Practice” for handling stormwater as it leaves a developed site and enters the surrounding waterways. The objective of Water Quality BMPs is to minimize contaminants that are present on developed land, such as sediment, debris, oils, and other pollutants, from being collected during rain events and entering local streams and rivers. B.Owner Contact: STAR Financial Bank Ryan McIntosh 735 Main Street Anderson, Indiana 46015 (765) 622-4135 Rayn.McIntosh@starfinancial.com C. The owner shall be responsible for all maintenance and costs associated with the BMPs for this development. D. The City of Carmel has Right-of-Entry to the development to inspect and maintain the BMP as necessary. Easements have been provided around the BMPs for this development. Figures showing these easements are included in this manual. E. BMPs for this development: 1. Pave Drain (Pervious Paver)- (See appendix A) Water coming from site will filter through the pave drain system and flow through under- drains to storm sewer 2. Underground Detention with Isolator Row (Proposed Detention System) – The stormwater that outlets from the existing drainage system flows into an underground detention system. The water will infiltrate through the ground and store water during storms. During large storms, the water will outfall through a proposed outlet control structure then to an 18” pipe into existing storm sewer. F. Specific maintenance guidelines are provided within this manual. STAR Financial Bank, or its delegated subcontractor will perform required BMP maintenance so long as STAR Financial Bank or its affiliates retains ownership of the subject property. G. See enclosed drawings for BMP locations, access easement, points of stormwater discharge from the site, and BMP details. H.Requirements regarding the submittal of annual inspection reports to the City of Carmel Engineering Department: The first report is due one year after construction is completed, with subsequent reports due each year within the same month of the initial report. If there are any deficiencies found during the inspection, these should be 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 faces enforcement action from the City.

Inspec tion is easily accomplished through the manhole or optional inspection ports of an Isolator Row. Please follow local and OSHA rules for a confined space entry. Inspection ports can allow inspection to be accomplished completely from the surface without the need for a con- fined space entry. Inspection ports provide visual access to the system with the use of a flashlight. A stadia rod may be inserted to determine the depth of sediment. If upon visual inspection it is found that sediment has accumulated to an average depth exceeding 3" (76 mm), cleanout is required. A StormTech Isolator Row should initially be inspected immediately after completion of the site’s construction. While every effort should be made to prevent sediment from entering the system during construction, it is during this time that excess amounts of sediments are most likely to enter any stormwater system. Inspection and maintenance, if necessary, should be performed prior to passing responsibility over to the site’s owner. Once in normal service, a StormTech Isolator Row should be inspected bi-annually until an understanding of the sites characteristics is developed. The site’s maintenance manager can then revise the inspection schedule based on experience or local requirements. 12.2 ISOLATOR ROW MAINTENANCE JetVac maintenance is recommended if sediment has been collected to an average depth of 3" (76 mm) inside the Isolator Row. More frequent maintenance may be required to maintain minimum flow rates through the Isolator Row. The JetVac process utilizes a high pressure water nozzle to propel itself down the Isolator Row while scouring and suspending sediments. As the nozzle is retrieved, a wave of suspended sediments is flushed back into the manhole for vacuuming. Most sewer and pipe maintenance companies have vacuum/ JetVac combi- nation vehicles. Fixed nozzles designed for culverts or large dia meter pipe cleaning are preferable. Rear facing jets with an effective spread of at least 45" (1143 mm) are best. The JetVac process shall only be performed on StormTech Rows that have AASHTO class 1 woven geotextile over the foundation stone (ADS 315ST or equal). Looking down the Isolator Row. A typical JetVac truck. (This is not a StormTech product.) Examples of culvert cleaning nozzles appropriate for Isolator Row maintenance.

Remove lid from floor box frame ii. Remove cap from inspection riser iii. Using a flashlight and stadia rod, measure depth of sediment iv. If sediment is at, or above, 3" (76 mm) depth proceed to Step 2. If not proceed to Step 3. B) All Isolator Rows i. Remove cover from manhole at upstream end of Isolator Row ii. Using a flashlight, inspect down Isolator Row through outlet pipe 1. Follow OSHA regulations for confined space entry if entering manhole 2. Mirrors on poles or cameras may be used to avoid a confined space entry iii. If sediment is at or above the lower row of sidewall holes [approximately 3" (76 mm)] proceed to Step 2. If not proceed to Step 3.

Consult with the manufacturer of the pipe header system for specific I&M procedures. Inspection of the header system should be carried out quarterly. On sites which generate higher levels of sediment more frequent inspections may be necessary. Headers may be accessed through risers, access ports or manholes. Measurement of sediment may be taken with a stadia rod or similar device. Clean - out of sediment should occur when the sediment volume has reduced the storage area by 25% or the depth of sediment has reached approximately 25% of the diameter of the structure. 12.4 ECCENTRIC PIPE MANIFOLD MAINTENANCE Cleanout of accumulated material should be accom- plished by vacuum pumping the material from the head- er. Cleanout should be accomplished during dry weath- er. Care should be taken to avoid flushing sediments out through the outlet pipes and into the chamber rows.

A: This will depend on the project. Following the initial installation, the PaveDrain system should be checked bi-monthly to assess the amount of infiltration still occurring. Ideally, the visual inspection should occur during a rain event. A residential or urban setting with a significant amount of debris may need to be checked more frequently in order to properly determine an appropriate maintenance schedule. Several options exist for maintenance of the PaveDrain system, (in order of preference); PaveDrain VAC Head, PaveDrain Air Compressor Wand, Vacuum truck, or as a last resort, mat or block removal and cleaning of the aggregate base. PaveDrain VAC Heads are available from local distribution. http://www.pavedrain.com/pdf/PaveDrain-Sales-Distribution-Partners.pdf The most effective tool is the PaveDrain VAC Head. A video of the PaveDrain VAC head in action is available on line. http://www.youtube.com/watch?v=l2U-4xsy3wo Unlike other permeable systems, even if maintenance is not regularly carried out the PaveDrain system can be back in working order by the PaveDrain VAC Head. Although not required, it is recommended that any existing vegetation be sprayed with an appropriate vegetation killer prior to use of the PaveDrain VAC Head. If a combination truck is not available, then the second best option is to utilize compressed air with a wand attachment. A video of this process is available on line. http://www.youtube.com/watch?v=ohy96g3PdGw The use of an air compressor with wand will NOT void the warranty of the PaveDrain system. Proper use of all equipment listed within the manual is to be expected. EXAMPLES of air compressor equipment are shown below. NOT AN ENDORSEMENT. Compressor Features  15.7 CFM@175 psi  Cast iron two stage compressor  Aluminum head for heat dissipation  8 Gallon Twin tank receivers  Manual drive valves for proper maintenance Generator  120 volts @60 Hz.  3.8 Hr. run time @full load  80.4 decibel rating  1.7 gallon fuel tank capacity The third maintenance option for the PaveDrain system is with a Vac truck. However, the thickness of the block (5.65”) can make this less than effective under most conditions. Especially when maintenance has not been carried out in quite some time and the area is not pre-wetted. Sweeping alone is not as effective because the debris is simply moved around as opposed to being removed. The PaveDrain joints are designed to be left open so that the operator of the vacuum truck can turn the equipment on its highest setting with little worry of damage to the system. http://www.elginsweeper.com/Products/AirSweepers/Whirlwind/tabid/109/Default.aspx The fourth option and the last resort is the removal of the blocks/mats and the subsequent cleaning of the aggregate layer. Once cleaned, then everything is RE- Installed as a sustainable stormwater solution.  SAFE  OHSHA Approved  Ergonomic  Made in USA Q: Can the PaveDrain System be snow plowed with steel snow plow blade? A: Yes. However, it should be noted that the edges of the block may be scored or slightly damaged by a steel snow blade. (SEE BELOW). Fast, Clean, Quiet Snow Removal: Our edges have a “squeegee action” to clean faster, better & much quieter than steel cutting edges. Q: Should the PaveDrain System be sealed? A: A sealant is not discouraged, but it is not mandatory. A sealant is an economical way to assist the PaveDrain System to resist the damage caused by salting of adjacent hardscape surfaces. Sealing of the PaveDrain System will increase its longevity. Some of the more popular brands are shown below. Both are available in 55 gallon drums. Natural Look – iN www.techniseal.com/web/product.php?prodID=291 Code Size Color Coverage 221- 318 55 gallons - Covers up to 6600 sq. ft. In order to minimize any surface damage to a PaveDrain block, the recommended snow plowing method would be with a rubber tipped snow blade. The following is an excerpt from a popular rubber snow blade provider. NOT AN ENDORSEMENT www.plowrubber.com Long Lasting: Our rubber snowplow edges are made of a tough, resilient rubber compound that shows very little wear after many hours of use. They can outlast steel edges many times. No Gouging: Rubber edges easily adjust to irregular road surfaces & pavement markers-without gouging. Rubber edges save you costly repairs to submerged lighting and surfaces such as cobblestone and brick. Its distinctive feature is its ability to protect without changing the appearance of the surface. As an oil repellent, it makes cleaning easier by preventing oil, grease (barbecue) and dirt from penetrating the material. As a water-repellent, it helps prevent the appearance of mold and protects against water damage. Easy to apply, it provides maximum effectiveness and durability. It won’t make surfaces more slippery and hence is ideal for protecting pool decks, patios, steps, sidewalks, etc. It resists the elements (freeze-thaw cycles, sun, rain, etc.), as well as salt. SRW (PS-X) Penetrating PAVER www.srwproducts.com SEALTM SSSPLUS10 55GAL 485 lbs Used to protect and seal any clean and dry cementitious surface, above ground, vertical or horizontal. It protects the surface against damaging effects of water intrusion, acid rain, deicing chemicals, freeze/thaw exposure, airborne dirt, smog, industrial fumes, and most other atmospheric chemicals. It retains the original appearance of pavers, brick, retaining walls, stone, masonry, cultured stone and concrete surfaces with a non-yellowing UV resistant finish. Q: Should the PaveDrain System be salted or sanded? A: A light salting is preferred over sanding. Covering the PaveDrain surface with a heavy salting is not recommended. Salting is hard on everything, sanding will help with traction, but also has the adverse effect of washing the sand between the joints and into the base material, which will decrease the performance of the base material. Of note, it will take years if not decades to show any decreased drainage performance to the PaveDrain System’s aggregate bedding layer in typical parking lot applications. Pre-wetting salt has become common. Wetting provides moisture to make brine. Faster melting action may be expected. In addition, the wet salt has less of a tendency to bounce off the surface during installation or by traffic therefore saving money. While any liquid de-icing chemical can be used to pre-wet, liquid calcium chloride is used widely. Applications of 6-10 gallons per cubic yard of salt are recommended. Calcium chloride has the added advantage of producing extra melting due to its effectiveness. Initial projects have shown a penchant for the surface of the PaveDrain System to remain dry and mostly…ice free. Stormwater does not collect on the top surface of the PaveDrain blocks; therefore it runs down the sides and into the base material. The only slipping issue that has been documented is early mornings where a frost cover has coated the surface of the blocks. Once the sun hits the surface, this is quickly melted and does not warrant a salting. Q: Can an individual PaveDrain Block be replaced? A: If a PaveDrain block breaks under pressure or sudden impact, it is easy to replace the single block without having to pull out the entire mattress. Follow these steps to repair a single block. Step 1 Step 2 Step 3 Break out the broken block using a 3 lb. hammer, being careful not to damage any surrounding blocks. It is best to start in the middle of the block and work your way out. A concrete masonry chisel can help as well. Once you have loosened the concrete, remove the remaining pieces from the area. If pieces are stuck, continue to use the hammer to break them free. Once the block is free, perform one final check to clear the cables and any block pieces that may have collected under adjacent blocks. Pull as much slack as possible from the cables. This will allow you to tuck the cable into the arch of the replacement bock. Step 4 Step 5 **If you have issues with the existing cable (as shown in Step 3 above) you can cut the cable and remove it from the hole. It will not affect the performance of the system. This will need to be noted on the mat layout or site plan drawings in the event the mats are required to be removed for utility work. Please go to www.pavedrain.com and review the Maintenance Video located under the “media” section or the “installation and maintenance” section of the site. Now that the damaged block is fully removed, you are ready to place the new block in. Line up the replacement block to fit the hole where the old block was. Slide the new block down into place. You may use a rubber mallet to tamp it down securely at the edges, be sure not to damage the new block by using your 3 lb hammer with too much force.
