HomeMy WebLinkAbout7.0 Stormwater Maintenance Plan 2019.05.20INSPECTION AND MAINTENANCE FOR
STORMWATER MANAGEMENT FACILITIES
The Property Owners Association shall be responsible for the maintenance of the stormwater
drainage facilities within the Jennifer Place Condominiums development.
Storm Water Facilities:
1. Drainage swales slope toward retention and detention ponds to collect storm water
runoff and channel it to the retention or detention pond.
2. Retention Ponds collect storm water runoff and store the water until it evaporates and/or
infiltrates into the ground.
Semi-Annual Inspection:
1. Check retention ponds three days following a storm event exceeding ¼ inch of
precipitation. Failure for water to percolate within this time period indicates clogging or
poor-draining soils. Clear any clogs and replace any poor-draining soils with well-
draining gravely soils.
2. Check for grass clippings, litter, and debris in drainage swales and retention ponds. Flush
and/or vacuum drywells or storm water pipes if excessive material is observed in the
facilities.
Standard Maintenance:
1. Remove sediment and oil/grease from retention ponds
2. Inspect and remove debris from drainage swales and retention ponds. Use a vacuum truck
to clean catch basins and dry wells.
3. Monitor health of vegetation and revegetate as necessary to maintain full vegetative
cover.
4. Inspect for the following issues: differential accumulation of sediment, drain time, signs of
petroleum hydrocarbon contamination (odors, oil sheen in pond water), standing water,
trash and debris.
Sediment accumulation:
In most cases, sediment from a retention pond does not contain toxins at levels posing a hazardous
concern. However, sediments should be tested for toxicants in compliance with current disposal
requirements and if land uses in the drainage area include commercial or industrial zones, or if
visual or olfactory indications of pollution are noticed. Sediments containing high levels of
pollutants should be disposed of in accordance with applicable regulations and the potential
sources of contamination should be investigated and contamination practices terminated.
