Stormwater Narrative
Parker Business Park
New Hanover County_ NC
TE 04026
Parker Business Park is a 2.82 acre existing vacant tract proposed for a commercial retail
and office complex. The site proposes 14,400 sf of buildings, 44,925 sf of asphalt parking
and 3,293 sf of concrete sidewalk. The total 62,618 sf area or 50.98% impervious will be
routed to proposed open infiltration basins.
The project owner and designer's envision the vegetated open basins linked together with
bio-log spillways to be a standout example for stormwater treatment. A cumulative total
of 3 inches of runoff will be treated and allowed to overflow across a 100 ft wide
vegetated filter. Runoff volumes will meet New Hanover County's 2, 10_ and 25-vear pre -
post requirements with a check for the 100-year storm. Overflow will route to a tributary
of Everet's Creek. classification SA.

Dear Robert:
In response to your email dated September 9, 2005, we offer the following:
1. The corrected infiltration basin supplement is enclosed.
2. A detail is provided on the C-3 sheet.
3. I did not misunderstand the 4" layer of sand. Every disturbed area on site is
required to be stabilized in accordance with the seeding specifications unless
otherwise noted. The back side of the basin is required to be vegetated much
more heavily, therefore we have noted this. We do not want this thick
vegetation within the basin, so I request not to add this note.
4. I used 30 bottom elevation and 33.5 spill elevation, therefore 3.5' in depth. I
then just divided the depth by the infiltration rate of 5". 42"/5"/hr = 8.4 hrs.
This type of calculation has nothing to do with the surface area of the bottom.
Please review for approval and contact us with any questions; comments or if you
need additional information. Thank you.
Sincerely,
Tripp Engineering, P.C.

Charlie,
I am writing the Parker Business Park permit. I still need a few clarifications.
* The total basin volume on the new calculation does not match the
volume and basin dimensions listed on the infiltration basin
supplement that I have on file. Could you send me an updated
supplement with corrected basin dimensions and volume? * Also, I don't know
how I forgot to mention this on the first
add -info; there is no detail for the infiltration swales. You
spoke of a 1.3' biolog dam in the narrative, but I need a detail
to approve. * Maybe you misunderstood the intent of the 4" sand layer. The
entire basin still needs to be vegetated (not just the back
side). The sand layer was necessary to remove the topsoil (which
is not suitable for infiltration) and replace with a more
permeable material. Please change the note to require vegetation
in the entire basin
* Please list the elevation and surface area in the basin that was
used to calculate the drawdown time (because the bottom is not
flat). It appears it was about half, but I was not sure.
Please give me a call if there are any questions. Thanks

Dear Robert:
In response to your correspondence dated August 30, 2005, we offer the following:
1. Bar scale has been corrected.
2. 15" pipes are to be used.
3. No wetlands exist on site. This has been noted.
4. The bottom and storage elevations have been noted.
5. A 4" layer of clean sand has been specified for the first two feet of storage,
30.0 - 32.0.
6. The basin bottom is proposed to meet the natural ground. This is shown by the
proposed contours tying into the existing within the bottom of the basin.
7. A stage storage calculation is enclosed.
8. We have clarified the filter to be 5:1. This will allow for a 27.5' x 100' filter.
Please review for approval and contact us.with any questions, comments or if you
need additional information. Thank you.
Sincerely,
Tripp Engineering, P.C.

Parker Business Park
New Hanover County
Dear Mr. Parker:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Parker Business Park on August 29, 2005. A preliminary review of that information has
determined that the application is not complete. The following information is needed to
continue the Stormwater review:
1. Please correct the bar scale on the site plan as well as the drainage area map.
2. Please clarify what size pipes will be used (both 15 and 18" are specified).
3. It is unclear if there are any wetlands on site. If not, please add a statement to the plans
that indicate there are no wetlands on site.
4. Specify the bottom and storage elevations on the basin detail.
5. Please specify a 4° layer of clean sand in the bottom of the infiltration basin (remove 4"
of topsoil)
6. Is the bottom of the basin sloped (natural ground) or is it to be graded flat? Please
clarify.
7. Please provide a stage storage chart for the basin in the calculation.
8. There are discrepancies with the proposed vegetated filter. The backside is specified
both 5:1 (site plan) and 6:1 (detail). The max length measured from the berm to the
property line is 20 ft (not 30), unless it is a scale issue (see #1).
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to September 8, 2005, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter. The
request must indicate the date by which you expect to submit the required information.

Storm water Narrative
Parker Business Park
New Hanover County, NC
TE 04026
Parker Business Park is a 2.82 acre existing vacant tract proposed for a commercial retail
and office complex. The site proposes 14,400 sf of buildings, 44,925 sf of asphalt parking
and 3,293 sf of concrete sidewalk. The total 62,618 sf area or 50.98% impervious will be
routed to proposed open infiltration basins.
The project owner and designer's envision the vegetated open basins linked together with
bio-log spillways to be a standout example for stormxvater treatment. A cumulative total
of 3 inches of runoff will be treated and allo-vved to overflow across a 100 ft wide
vegetated filter. Runoff volumes will meet New Hanover County's 2, 10, and 25-year pre -
post requirements with a check for the 100-year storm. Overflow will route to a tributary
of Everet's Creek, classification SA.
