Dear Linda:
Attached for your review are three copies each of revised sheet C-1 and C-2. Sheet C-1 has been
marked with the drainage basins. The revisions should address your comments of April 9, 1997.
1. The drainage areas are marked on sheet C-1. This information was marked up for inclusion with
the last submittal, but apparently did not make it to your office. I apologize.
2. The dimensioned area of Contour 19.3 for Basin 1 was within 2 percent of that shown in the
calculations. The long leg of the basin has been widened 5 inches. The Basin #3 dimensioned
contour area (22.8) was 1 percent above that of the calculations. My calculations of the contour
area are attached. T;�e areas shwitin are adequatC to fiieet tiir 610(age cri eria.
3. The square footage shown on the plans is heated square footage, as is the customary convention.
The dimensioned impervious surface was used for calculation and is now shown on the plans.
4. We will remind the Owner that the original Operation and Maintenance Plan is required.
Sincerely,

Dear Mr. Sneeden:
The Wilmington Regional Office received previously requested information for the Stormwater
Management Permit Application for Primrose Medical Center on April 1, 1997. 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. As previously requested, please provide a drainage area map.
2. Based on the storage contour dimensions provided, I am still unable to verify the storage
volumes shown in the calculations. Please msize basins 1 and 3 to provide additional storage.
3. The given building dimensions do not multiply out to 9,657 square feet. Please revise.
4. The original Operation and Maintenance Plan has not yet been received.

Attached are three sets of revised plans and signed O&M agreement. The plans reflect
your comments of March 13,1997, notwithstanding the following similarly numbered
exceptions or comments.
3. T he originai agreement will be forwarded upon receipt.
12. The grading in the area of the 16th Street driveway maximizes the area draining
into the infiltration basins. A curb cut has been added to increase the area. With
the relatively steep grades, driveway entrance, handicap access, and the
medical use of the site, I hesitate to provide more of a roller -coaster ride in order
to increase infiltration coverage by a few square feet. This design provides for a
minimal amount of run-off being untreated.
14. The sites to the south of this tract do not drain onto this property.

Dear Mr. Sneeden:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Primrose Medical Center on March 7, 1997. 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 provide the finish contours in the 17th Street side parking lot, ie., the 27, 28 and 29
contours are missing.
2. Indicate the roof drain locations. Add a note to the plans that roof drains must be located so
as to be picked up by one of infiltration basins.
✓ 3. A signed Operation and Maintenance Plan.
v""'4. Delineate all wetlands on site, or note on the plans that none exist.
2 5. Delineate/highlight the drainage area to each basin.. Nab Ord v4ed
✓6. Delineate the storage contour in each basin.
V,`�7. Please number the basins to correspond to the calculations.
\OlC'\ 8. What is the elevation of the back of the sidewalk along 16th Street?

9. Several areas will need to be regraded in order for the runoff to get into the catch basins. At
the NW corner of the parking area, the top of CB lA is 19.9, but the pavement around the
comer is at 19.5 and 19.7, which makes the corner the low spot. Please raise the pavement
elevation in the NW corner to drain to basin 1A. At the dumpster pad, the back is at 19.9,
but the grade break is at 20.3, making it impossible for the runoff to get into Catch Basin 2.
Please raise the back elevation of the dumpster pad.
✓ 10. Add a spot elevation at the end of the long arm of Basin V.
.�5
ny� /11. Provide dimensions of the basin bottom contours, and a cross-section indicating the 3:1 or
flatter side slope.
✓12. Add catch basins and pipe to Basin II at the driveway cut onto 16th Street, where a chunk of
the pavement is allowed to bypass the infiltration system. Reposition the 20 contour there to
direct runoff into the basins.
13. Is the City OK with using the streetyard as part of the infiltration system? What about the
impact of trees and shrubbery on the functioning and maintenance of the system?
,% 14. There appears to be some off -site runoff into Basins II, V, and VI from the Burgess site and
0\ the Simmerman site. Please account for this runoff or redirect it.
�y►
_ 15. The basins surface areas reported in the calculations do not match up the the scaled areas I
get from the contour lines drawn on the plans. Please make sure that the contours accurately
reflect the proposed condition.
16. Several of the top of pavement and top of curb elevations are switched around. Please correct.
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 April 13, 1997, or the application will be
returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
