Compliance with Stormwater Best Management Requirements It is the property owner’s responsibility to inspect and maintain the stormwater infrastructure installed on the subject property as described within the City’s Urban Runoff Management Plan and attached Stormwater Maintenance Agreement. Therefore, it is important that the property owner or assigned property manager understands the overall operations of the stormwater mitigation system as well as how to inspect and maintain this infrastructure. This document outlines the overall operational aspects of the stormwater mitigation improvements as well as the maintenance associated with the various components of the system. A copy of the Grading and Drainage Certificate is included as Exhibit A which illustrates the overall storm water mitigation improvements installed at the property. B. Stormwater Infrastructure Operations Burlingame Ranch Affordable Housing is a multi-family development project located within the City of Aspen, State of Colorado. The site is accessed off State Highway 82 via Harmony Road. The subject property consists of the previously constructed Phase I and Phase II subdivisions with Phase 3 completing the remaining 79 units. The Phase III improvements are primarily located along both sides of Paepcke Road and are primarily broken into two primary drainage collection systems with different ultimate discharge points. System 1 includes drainage facilities that ultimately contributing runoff that ultimately discharges to the existing Harmony Pond. Harmony Pond is an existing stormwater detention pond located within Harmony Park, which lies at the southeast corner of the Harmony Road/Forge Rd intersection. Runoff tributary to Harmony Pond primarily includes the southern portion of Deer Hill, a portion of Building 9, Buildings 10-15, Residential Lots 3-4, parking areas P10-P14, Park 3, and approximately 825 feet of Paepcke Road. Phase III rain gardens tributary to Harmony Pond all have a “B” suffix in their rain garden identifier as depicted on the attached Stormwater Maintenance Map (i.e. “1B”). System 2 describes the drainage facilities contributing runoff to the existing Pond 2 located within Park 1, near the southern extents of the Phase II improvements. Runoff from the Phase III improvements tributary to Pond 2 includes portions of Buildings 8 & 9, and approximately 1,870 feet of Paepcke Road. Phase III rain gardens tributary to Pond 2 all have a “A” suffix in their rain garden identifier as depicted on the attached Stormwater Maintenance Map (i.e. “1A”). C. Stormwater Maintenance & Inspection Recommendations Owners, or their assigned property managers, are required to maintain all stormwater management facilities outlined within this plan. It is important that the individual(s) responsible for the maintenance have a complete understanding of the entire drainage system as well the associated maintenance and inspection requirements. A copy of the Maintenance Agreement and Grading and Drainage Certificate are provided as attachments for referencing purposes. In addition, blank inspection logs are provided as an attachment and should be filled out and filed onsite whenever routine inspections are performed. Inspection recommendations for the various stormwater improvements outlined above are provided below. Burlingame Ranch Affordable Housing – Phase III Stormwater Operation & Maintenance Plan Rain Gardens (RG) Operations: Rain gardens are depressed landscaping areas designed to capture and filter or infiltrate the water quality capture volume into the underlying soils. The grow media/filter material consists of a mixture of sand with high quality topsoil (60%-70% sand & 30%-40% topsoil). The depth of grow media shall be 18-inches min. The subject property has multiple rain gardens located throughout the development as depicted on the attached Stormwater Operations & Maintenance Exhibit. Inspection and maintenance of the respective rain gardens should be performed annually (at a minimum) by a qualified individual and should include the following tasks: Maintenance: RAIN GARDEN DATE INSPECTED [ ] Drainage System Feature Potential Defect Conditions When Maintenance is Needed Results Expected When Maintenance is Performed or Note Needed [ X ] Sediment accumulation Sediment depth exceeds 1/2 inch No sediment deposit that would impede permeability of the filter section [ ] Trash and debris Trash and debris accumulated on rain garden bed Trash and debris removed from rain garden [ ] Sediment/ debris in cleanout When the clean-out becomes full or partial plugged with sediment and/or debris Sediment removal from clean-outs [ ] Filter media Drawdown of water through the filter media takes longer than 24 hours, and/or flow through the overflow pipes occurs frequently Top several inches of media are scraped. May require replacement of entire filter media depth depending on extent of plugging (a sieve analysis is helpful to determine if the lower sand has too high a proportion of fine material) [ ] Prolonged flows Sand is saturated for prolonged periods (several weeks) and does not dry out between storms due to continuous base flow or prolonged flows from detention facilities Low, continuous flows are limited to a small portion of the facility by using a low wooden divider or slightly depressed sand surface [ ] Short circuiting When flows become concentrated over one section of the sand filter rather than dispersed Flow and percolation of water through filter media is uniform and dispersed evenly across the entire bed area [ ] Erosion damage to slopes Erosion where cause of damage is prevalent or potential for continued erosion is evident Slopes stabilized using proper erosion control measures [ ] Scour at inlet Soil beneath inlet erosion control is visible Replace inlet erosion control pad [ ] Damaged pipes Any part of the piping is crushed or deformed more than 20% or any other failure to the piping Pipe repaired or replaced [ ] General Permeable Pavers (PP) Operations: Permeable pavers, also known as permeable interlocking concrete pavements (PICP), are installed with layers of varying-sized stone and are designed to infiltrate captured stormwater runoff into the existing underlying soils. Maintenance of permeable pavers should be minimal but is critical to ensure the system functions effectively. Permeable pavers are located in multiple locations beneath the parallel parking areas along Paepcke Road as depicted on the attached Stormwater Operations & Burlingame Ranch Affordable Housing – Phase III Stormwater Operation & Maintenance Plan Maintenance Exhibit. Permeable pavers located in the parallel parking areas in front of Buildings A9, B9, A8 and B8. All permeable paver areas have a perforated underdrain collection pipe with an at grade cleanout located on the upstream end of the paver area. Maintenance: PERMEABLE PAVERS DATE INSPECTED [ ] Drainage System Feature Inspection Conditions When Maintenance is Needed Results Expected When Maintenance is Performed or Note Needed [ X ] Annually Routine maintenance as needed Clean pavement surface using one or a combination of the following methods: (1) Remove sediment, debris, trash, vegetation, and other debris deposited onto pavement (rakes and leaf blowers can be used for removing leaves). (2) ShopVac or brush brooms (small areas). (3) Vacuum/sweep permeable paving installation using high efficiency regenerative air or vacuum sweeper. Note: Vacuum settings may have to be adjusted to prevent excess uptake of aggregate from paver openings or joints. Vacuum surface openings in dry weather to remove dry, encrusted sediment [ ] Annually Surface is clogged: Ponding on surface or water flows off the permeable pavement surface during a rain event (does not infiltrate) (1) Review the overall performance of the facility (note that small clogged areas may not reduce over- all performance of facility). (2) Test the surface infiltration rate using ASTM C1701 as a corrective maintenance indicator. If the results indicate an infiltration rate of 10 inches per hour or less, then perform corrective maintenance to restore permeability. Clogging is usually an issue in the upper 2 to 3 centimeters of aggregate. Remove the upper layer of encrusted sediment, and fines, and/or vegetation from openings and joints between the pavers by mechanical means and/or suction equipment (e.g., pure vacuum sweeper) [ ] Annually Sediment present at the surface of the pavement Assess the over-all performance of the pavement system during a rain event. If water runs off the pavement and/or there is ponding, then see above. Determine source of sediment loading and evaluate whether or not the source can be reduced/eliminated. If the source cannot be addressed, consider increasing frequency of routine cleaning(e.g., twice per year instead of once per year) [ ] Annually Paver block missing or damaged Remove individual damaged paver blocks by hand and replace or repair per manufacturer's recommendations [ ] Annually Loss of aggregate material between paver blocks Refill per manufacturer's recommendations for interlocking paver sections [ ] Summer Weeds or grass inhibit infiltration Manually remove weeds and grass. Presence of weeds may indicate that too many fines are present (refer to Actions Needed under "Surface is clogged" to address this issue) [ ] Interlocking concrete paver blocks Drywells (DW) Burlingame Ranch Affordable Housing – Phase III Stormwater Operation & Maintenance Plan Operations: Drywells are a permanent structural Best Management Practice (BMP) that incorporates manhole structures with perforated barrels at the deeper depths to allow infiltration of captured stormwater runoff into the underlying soils. There are two separate drywells within the development and are depicted on the attached Stormwater Operations & Maintenance Exhibit. Collected stormwater is routed subsurface to the respective drywell’s storm water collection pipes as noted above. Each of the storm drains enter the dry well structure within the upper chamber which contains a perforated riser pipe (“gooseneck”) wrapped with filter fabric. This upper chamber is intended to capture sediment and debris prior to runoff entering the lower chamber. The lower chamber is the infiltration component of the structure and consists of a concrete structure with perforated side walls. Washed screened rock is installed around the exterior of the perforated sections to help promote collected and treated stormwater to infiltrate into the underlying soils. Inspection of the dry well structures should be performed by an individual qualified to work in confined spaces and may include the following tasks: Maintenance: DRYWELL DATE INSPECTED [ ] Drainage System Feature Potential Defect Conditions When Maintenance is Needed Results Expected When Maintenance is Performed or Note Needed [ X ] Does not dissipate stormwater Does not dissipate stormwater Replace or repair [ ] Opening clogging Openings are clogged, reducing capacity Water-jet clogged openings [ ] Trash and debris Trash, debris, or floatables that impact functionality No trash or debris in drywell [ ] Sediment Sediment in drywell exceeds 60% of the depth below the inlet pipe No sediment in drywell [ ] Structure damage Maintenance person judges the structure is unsound Drywell replaced or repaired to design standards [ ] Contaminants and pollutants Any evidence of oil, gasoline, contaminants, or other pollutants, sheen, obvious oil or other contaminants present. (1) Identify and remove source AND (2) Report to City of Aspen Engineering Department No contaminants or pollutants present [ ] Cover not in place Cover is missing or only partially in place. Any open cover requires maintenance Cover is closed [ ] Cover difficult to remove One maintenance person cannot remove lid after applying normal lifting pressure (intent is to keep cover from sealing off access to maintenance) Cover can be removed by one person [ ] Trash and debris Trash and debris that is blocking more than 20% of grate surface inletting capacity Grate free of trash and debris [ ] Damaged or missing Grate missing or broken member(s) of the grate Grate is in place and meets design standards [ ] General Drywell manhole Metal Grates (if Applicable) Storm Pipe & Inlets Burlingame Ranch Affordable Housing – Phase III Stormwater Operation & Maintenance Plan Operations: Storm pipe, inlets and gutters are located throughout the site to collect and convey collected surface water runoff. Inlet and stormwater collection pipes are depicted on the attached Stormwater Operations & Maintenance Exhibit. Maintenance: INLETS DATE INSPECTED [ ] Drainage System Feature Potential Defect Conditions When Maintenance is Needed Results Expected When Maintenance is Performed or Note Needed [ X ] Trash or debris which is located immediately in front of the catch basin opening or is blocking inletting capacity of the field inlet by more than 10% No trash or debris is located immediately in front or on grate opening [ ] Trash or debris (in the field inlet) that exceeds 60% of the sump depth as measured from the bottom of basin to invert of the lowest pipe onto or out of the basin, but in no case less than a minimum of six inches clearance from debris surface to the invert of lowest pipe No trash or debris in the field inlet [ ] Trash or debris in any inlet or outlet pipe blocking more than 1/3 of its height Inlet and outlet pipes free of trash or debris [ ] Dead animals or vegetation that could generate odors that could cause complaints or dangerous gasses (e.g. methane) No dead animals or vegetation present within the field inlet [ ] Sediment Sediment (in the basin) that exceeds 60% of the sump depth as measured from the bottom of basin to invert of the lowest pipe into or out of the basin, but in no case less than a minimum of six inches clearance from the sediment surface to the invert of the lowest pipe No sediment in the field inlet [ ] Top slab has holes larger than two square inches or cracks wider than 1/4 inch. (Intent is to make sure no material is running into basin) Top slab is free of holes and cracks [ ] Frame is not sitting flush on top slab, i.e. separation of more than 3/4 inch of the frame from top slab. Frame not securely attached. Frame is sitting flush on the riser rings or top slab firmly attached. [ ] Maintenance person judges that structure is unsound Basin replaced or repaired to design standards [ ] Grout fillet has separated or cracked wider than 1/2 inch and longer than one foot at the joint of any inlet/outlet pipe or any evidence of soil particles entering field inlet through cracks Pipe is regrouted and secure at basin wall [ ] Settlement/ Misalignment If failure of basin has created a safety, function, or design problem Basin replaced or repaired to design standards [ ] Vegetation growing across and blocking more than 10% of the basin opening No vegetation blocking opening to basin [ ] Vegetation growing in inlet/outlet pipe joints that is more that is more than six inches tall and less than six inches apart No vegetation or root growth present [ ] Contaminants and pollution Any evidence of oil, gasoline, contaminants, or other pollutants, sheen, obvious oil or other contaminants present. (1) Identify and remove source AND (2) Report to City of Aspen Engineering Department No Contaminants or pollutants present [ ] Vegetation Fractures or cracks in basin walls/bottom Structure damage to frame and/or top slab Trash and debris General Open Channels/Swales: Burlingame Ranch Affordable Housing – Phase III Stormwater Operation & Maintenance Plan Operations: Numerous shallow vegetated swales are located throughout the development to convey collected surface water runoff to specific design points. An additional vegetative swale is located north of the development and is designed to collect offsite runoff from the vegetated hillside above the improvements and route it around the development. Swales requiring routine inspection and maintenance are depicted on the attached Stormwater Operations & Maintenance Exhibit. Maintenance: SWALE DATE INSPECTED [ ] Drainage System Feature Potential Defect Conditions When Maintenance is Needed Results Expected When Maintenance is Performed or Note Needed [ X ] Sediment accumulation on grass Sediment depth exceeds two inches Remove sediment deposits on grass treatment area of the swale. When finished, swale should be level from side to side and drain freely. There should be no areas of standing water once inflow has ceased. [ ] When water stands in the swale between storms and does not drain freely Any of the following may apply: sediment or trash blockages removed, grade from head to foot of swale improved, clogged check dams removed [ ] Poor vegetation coverage When grass is sparse or bare or eroded patches occur in more than 10% of the swale bottom Grass growth is determined to be poor and that condition corrected. Plugs of grass from the upper slope are re-planted: planted in the swale bottom at 8 inch intervals or re-seeded into loosened, fertile soil [ ] Vegetation When grass becomes excessively tall (greater than 10 inches); when nuisance weeds and other vegetation starts to take over Mow vegetation or remove nuisance vegetation so that flow not impeded. Mow grass to a height of three to four inches. Grass clippings removed [ ] Excessive shading Grass growth is poor because sunlight does not reach swale If possible, over-hanging limbs trimmed back and brushy vegetation on adjacent slopes removed [ ] Inlet/outlet Inlet/outlet areas clogged with sediment and/or debris Remove material so there is no clogging or blockage in the inlet and outlet area [ ] Trash and debris Trash and debris accumulated in the swale Remove trash and debris from swale [ ] Eroded or scoured swale bottom due to flow channelization, or higher flows For ruts or bare areas less than 12 inches wide, the damaged area repaired by filling with crushed gravel. If bare areas are large, generally greater than 12 inches wide, the swale should be re-graded and re-seeded. For smaller bare areas, over seed when bare spots are evident, or take plugs of grass from the upper slope and plant in the swale bottom at 8 inch intervals [ ] General D.
