STORMWATER MAINTENANCE PLAN FOR THE PINES APARTMENTS PHASE II
PLANNING APPLICATION # 22-341
Responsible Party for Operation and Maintenance: Rustic Home, LLC.
The following facilities will be inspected and identified deficiencies shall be corrected. Clean-
out must include the removal and legal disposal of any accumulated sediments and debris from
the entire stormwater management system.
Storm Water Facilities:
1. Pipe Networks convey storm water to different discharge locations underground.
2. Inlets are facilities where storm water runoff enters a pipe network. Inlets include storm
water manholes and drains.
3. Catch Basins are sumps typically located directly below storm water inlets and allow
sediment to settle before storm water enters the pipe network.
4. Outlets are points where storm water exits a pipe network.
5. Drywells/Gravel Pits are underground storm water collection facilities that collect and
temporarily store runoff from roof tops and landscaped areas before allowing storm water
to infiltrate into the ground.
Post Construction Inspection:
1. Observe drain time in retention facilities for a storm event after completion of the facility
to confirm that the desired drain time has been obtained. If excessively slow infiltration
rates are observed, then excavate a minimum 5 ft by 5 ft drain to native gravels (or native
well-draining material) and backfill with well-draining material (pit-run).
2. Observe that drywells/gravel pits, catch basins, and outlet structures are clear of any
material or obstructions in the drainage slots. Inspect these structures to ensure proper
drainage following a storm event. Immediately identify and remove objects responsible
for clogging if not draining properly.
Semi-Annual Inspection:
1. Check drywells 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, catch basins,
drywells/gravel pits, and culverts. Flush and/or vacuum drywells/gravel pits or storm
water pipes if excessive material is observed in the facilities.
Standard Maintenance:
1. Remove sediment and oil/grease from retention facilities.
2. Inspect and remove debris from drainage swales, catch basins, and drywells/gravel
pits/boulder pits. Use a vacuum truck to clean catch basins and drywells/gravel pits.
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.
Note on sediment disposal:
In most cases, sediment from a detention 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.
Design Life:
In most cases, storm water facilities have a design life of 15-20 years if properly inspected and
maintained. When storm water facilities need to be replaced, it is the responsibility of the property
owner to determine which component needs to be replaced and scheduling the replacement
installation.
