DWQ project # 00-1449
February 26, 2007 Comments from DWQ
Reviewer: Annette Lucas
Land Design contact: Julie Roberts
1. Please redesign Extended Detention Wetland #1 so that all stormwater runoff is
directed to a single forebay. Also, please place the inlet and outlet pipes as far
apart as possible to maximize the flow path and improve the wetland's pollutant
removal capability.
RESPONSE:
As discussed in the phone conversation with Annette Lucas on March 1St, 2007,
construction for this project is already underway. Therefore, it would be difficult
to revise the storm piping into the wetland. The fine grading for this wetland was
revised to create a sort of baffle between the forebays and the micropool. This
will increase detention time in the wetland.
2. Please redesign Extended Detention Wetland #2 to maximize the flow path
between the inlet and outlet pipes.
RESPONSE:
See response to comment 1 above. Fine grading for Wetland #2 was revised to
provide for increased detention time.
3. Please include a separate extended detention wetland worksheet for each of the
proposed constructed wetlands.....
RESPONSE:
These worksheets have been provided.
4. Please provide all information requested in the extended detention wetland
worksheets, including a planting plan with plant species and densities and nursery
and soil specifications.
RESPONSE:
See sheets C-15 through C-17b.
5. Please provide all the information requested in the bioretention worksheet,
including: soil specifications, aprofile of the soil layers and underdrain system, a
planting plan with plant species and densities, and plan details for the inlet and
outlet structures.
RESPONSE:
See sheets C-15 through C-17b.
6. Please provide plan details for the level spreader....

CERTIFIED MAIL: RETURN RECEIPT REQUESTED
Mr. Bob Dienst

Mooresville, NC 28117
Subject Property: Catawba Hills Subdivision, Village D - Townhomes
REQUEST FOR MORE INFORMATION
Dear Mr. Dienst:
On Apri18, 2003, the Division of Water Quality (DWQ) issued a 401 Water Quality Certification to
impact to impact 0.18 acre of wetland and 600 linear feet of stream or waters for the purpose of
constructing a residential subdivision you described. in your application dated November 17, 2000. In
order to meet Condition 4 of the 401 Certification for this project, a revised stormwater management plan
was submitted to the DWQ on November 15, 2006. The DWQ has determined that your stormwater
management plan was incomplete as discussed below.
Additional Information Requested:
1. Please redesign Extended Detention Wetland #1 so that all stormwater runoff is directed to a single
forebay. Also, please place the inlet and outlet pipes as far apart as possible to maximize the flow
path and improve the wetland's pollutant removal capability.
2. Please redesign Extended Detention Wetland #2 to maximize the flow path between the inlet and
outlet pipes.
3. Please include a separate extended detention wetland worksheet for each of the proposed
constructed wetlands. Currently, the submittal only includes one worksheet and it is for a wet
detention basin, not an extended detention wetland. The extended detention wetland worksheet is
available on our web site at: http://h2o.enr.state.nc.us/ncwetlands/wetlndwk.pdf.
4. Please provide all information requested in the extended detention wetland worksheets, including a
planting plan with plant species and densities and nursery and soil specifications.
5. Please provide all the information requested in the bioretention worksheet, including: soil
specifications, aprofile of the soil layers and underdrain system, a planting plan with plant species
and densities, and plan details for the inlet and outlet structures.
6. Please provide plan details for the level spreader. The DWQ highly recommends that the level
spreader include a concrete lip to avoid failures and maintenance problems in the future.

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, ri~rap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
.reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The mtasuring device used to detetniine`the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads o.s3 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads o.s3 ~ feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be minimized to the maximum extent practical.

' Level spreaders in series can be used on slopes of up to 15°~ in forested areas with leaf littler cover or on slopes of up to 25% in areas
with thick ground cover or grass if designed according to the Draft Level Spreader Design Option Document. This potentially requires a
minor variance in protected buffer areas. In any event the second level spreader cannot be located in Zone 1 of a protected buffer area.

Bioretention Facilities Operation and Maintenance Agreement
The homeowners association is responsible to periodically clean the facility, remulch and replace dead,
dying or diseased plant material. Under no circumstances will there be allowed to have any sediment or
erosion transported material to the bioretention facilities of any other influent which may create an
impermeable layer on the facilities.
The bioretention system is defined as the retention area (ponding area), mulch and landscaping within the
retention area, amended soil or planting soil subgrade and subdrain with gravel bed and filter fabric.
For the first couple of years, plants and trees may need water until they become established.
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Visually inspect and repair any eroded areas, remove trash and debris. '
b. Re-mulch any void areas by hand 'as needed.
c. After rainstorms, inspect the retention cell and make sure drainage paths are clear and
that ponding water dissipates over 4-6 hours. Keep in mind, the bioretention cell is not a pond
should not provide a breeding ground for mosquitoes. Mosquitoes need at least 4 days of
standing water to develop as larva.
d. Weed regularly, if needed.
2. Every 6 months:
a. Add a fresh layer of mulch °as needed. The previous mulch may be removed and discarded to an
appropriate disposal area or retained if it is decayed. The mulch should be placed to depths not to
exceed 3". Seeded ground cover.or grass areas should not receive mulching.
b. Visually inspect vegetation for disease or pest problems, if treatment is warranted use least toxic
approach. Remove and replace all dead and diseased vegetation considered beyond treatment.
3. Annually:
a. Check the pH of the planting soils. Apply an alkaline. product, such as limestone, if needed.
b. Prune excess growth. Trimmed materials may be recycled back in the replenished mulch or
land filled if there is a concern of heavy metals accumulation.
c. Core aeration or cultivating of unvegetated areas may be required to ensure adequate filtration.
d. The overflow structure should be inspected to ensure that it is functioning. Accumulated
trash and debris sfiould be removed as necessary.

I acknowledge and agree by my signature below that I am responsible for the performance of the seven
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to
any changes to the system or responsible party.
