Re: Falls Village Shopping Center Variance Request
Wake County
Dear Mr. Rice:
As you are aware, the North Carolina Environmental Management Commission (EMC)
granted Agora Developments , LLC a variance from the Neuse River riparian buffer
rules (T15A. NCAC 2B .0233) for the proposed expansion of the Falls Village Shopping
Center at 6683 Falls of the Neuse Road in Raleigh. The variance was granted for the
proposed shopping center expansion and stormwater treatment as shown on the plats
dated May 11, 1999. The EMC also requested that a conservation easement be placed on
the remaining riparian buffers on the property to protect them from impacts in the future.
Agora Developments will now need to submit a completed Pre-construction Notification
(PCN) application for authorization under the US Army Corps of Engineers 404 permit
program and the Division's 401 water quality certification program. Along with the PCN
form to the State, you should include a payment of $475.00 for the 401 application fee
and the conservation easement that you propose for the remaining riparian buffer areas.
If you have any questions concerning this matter, please feel free to call Pete Colwell or
myself at 733-1786.
Sincerely,
Cc: Steve Mitchell, Raleigh Regional Office

GENERAL
SUMMARY OF PROCEDURE AND RESULTS
The proposed project will consist of constructing multiple 1-story buildings and two 2-story
building additions within an existing shopping center. The project will have a total of
249,500 square feet of gross building area and approximately 519,500 square feet of
parking areas and drives.
• The undeveloped portion of the site proposed for expansion contains a Neuse River Basin
Stream and associated buffers. As mitigation for disturbing the NRB Stream Buffer the
developer proposes to construct an engineered wetland. The wetland is designed to trap
and settle out suspended solids in stormwater runoff from a majority of the existing
shopping center, all of the proposed shopping center addition, and,offsite existing
development consisting of a country club and golf course, an apartment complex, and
single family subdivisions. The developer also proposes to maintain an existing 100 foot
wide natural buffer along the north properly line that will "filter" storm water runoff from
existing developed single family subdivision lots.
• The drainage area that will be treated consists of 33.4 acres (see attached page). The
on-site drainage is from the shopping center and is 52.5% (17.5 acres) of the total
drainage area. The developer proposes to construct a "wet" pond in accordance with the
Stormwater Best Management Practices handbook of the North Carolina Department of
Environment and Natural Resources.
DESIGN PARAMETERS
The engineered wetland was designed in accordance of NCDEHNR Best Management
Practices.

METHODOLOGY
' • To model the detention pond the HydraflowTM "Hydrographs for Windows" by Intelisolve
software package was used.
• This software created an inflow hYdro9raPh based on drainage basin characteristics input
by the user.
' • The user modeled the wetland as a reservoir, which was used as the basin of interest. The
inflow hydrograph was routed through the designed pond and the stage-storage, stage-
discharge and drainage characteristics were plotted.

Part 2: Demonstration of Need for a Variance
NOTE The variance provision of the Neuse Riparian Area Rule allows the Environmental Management
Commission to grant a variance to an affected party when the following conditions apply on a given project
(a) pracdcal difficuldes or hardships would result from strict application of the rule:
(b) such difficulties or hardships result from condidos which are peculiar to the property involved; and
(c) the general purpose and intent of the Rule would be preserved, water quality would be protected and
substantial justice would be done if the variance were granted.
This part of the application is to explain how the project meets criteria (a) and (b).
1. Attach a detailed description (2-3 pages) explaining the following:
• The practical difficulties or hardships that would result from strict application of the Rule.
• How these difficulties or hardships result from conditions that are unique to the property
involved.
• Why reconfiguring and/or reducing the built-upon area to preserve a greater portion of the
riparian area is not feasible on this project. If economic hardship is the major
consideration, then include a specific explanation of the economic hardship and the
proportion of the hardship to the entire value of the project.
Part 3: Water Quality Protection
NOTE: This part of the application is to explain how the project meets criterion (c): the general purpose and
iintant of the RLda woaL-f be presereedl water quality .could be protected and subs anuaf jusdca would be done if
the variance were granted.
11, Briefly summarize how water quality will be protected on this project. Also attach a detailed
narrative (1-2 pages) describing the nonstructural and structural measures that will be used
for protecting water quality and reducing nitrogen inputs to surface water.

PRACTICAL DIFFICULTIES OR HARDSHIPS
The site containing the Neuse Riparian Area is a 25.2 acre tract of land, of which,
17.4 acres was developed as a shopping center in the 1970's and 7.8 acres that has
remained undeveloped. It is the intention of the developer to redevelop and provide a
face lift to the existing buildings and.expand the site by building new shops and a free
standing retail building on the undeveloped portion of the site.
The property is located in a heavily developed urban environment and the
undeveloped land is irregularly shaped from a road frontage and accessibility
standpoint. These two factors are unique to this property when comparing it to other
undeveloped sites normally found at the periphery of urban settings. Current zoning
and zoning conditions, buffer requirements, building setbacks, and the site topography
also contribute to limiting development options, especially in light of the Neuse
Riparian Area being located in the middle of the undeveloped portion of the property.
According to zoning conditions, a 100-foot wide undisturbed buffer along the
northern property line must be provided. The buffer extends a distance of 740 feet for
a total of 1.7 acres, or 22% of the undeveloped portion of the site. A separate area
consisting of a perimeter band of residentially zoned land, 1.3 acres, comprises 17%
of the undeveloped portion of the site. In addition, there exists approximately 0.5
acres of Neuse Riparian Area outside of the 100-foot wide buffer and the residentially
zoned area, or 6% of the undeveloped portion of the site. The total unusable area is
3.5 acres, or 45% of the undeveloped portion of the site.
In order for the developer to make it financially feasible to upgrade the existing
shopping center it will be necessary to develop the undeveloped portion of the site, in
particular a portion that is covered by a Neuse Riparian Area. Initial plans called-for
disturbing approximately 650 lineal feet of the Neuse Riparian Area. After meeting
with DWQ Staff to review our proposed plan, we reduced the length of disturbance by
more than 200 feet to substantially minimize the affected area. In addition, the
developer proposes to install and maintain an engineered wetland and storm water
detention basin to remove dissolved nutrients and suspended particles. Marsh areas
provided within the engineered wetland will contain plants that effectively remove
urban pollutants.
Extensive landscaping and buffering will be installed and will serve a dual purpose.
First, to screen adjacent developed and undeveloped. residential property, and second,
to provide additional areas to infiltrate and cleanse storm water runoff. The site plan
currently before the City of Raleigh for consideration and approval will add 184 new
trees and 2074 new shrubs to the existing developed shopping center. The proposed
addition to the shopping center will include 148 new trees and 1228 new shrubs. In
addition, the proposed engineered wetlands and storm water detention basin will treat
the storm water runoff from 8.2 acres of offsite development consisting of a portion of
a country club and golf course, an apartment site, and commercial sites.
This commercial site cannot be feasibly developed without a variance. The east-west
Neuse River buffer extends to the existing developed shopping center. Any expansion
of the existing center will encroach into the buffer regardless of configuration. We
have reduced the impact to buffer by reconfiguring the site and providing building
walls which serve as retaining walls. This reconfiguration arose from our meeting with
DWQ staff. Without the approval of the variance, neither the shopping center
expansion nor the wetland/detention basin construction will occur. If the constructed
wetlands are not built, then the untreated runoff from the 25.6 developed acres in the
33.4-acre watershed will continue to flow without any filtering or detention. It is the
opinion of the Engineer that the storm water quality, from a nutrient loading
standpoint, to the Neuse River Buffer will be greatly enhanced. The water quality
improvements that will be installed as part of the shopping center redevelopment will
remove pollutants from both existing development runoff and new construction runoff.
The owner of the shopping center purchased the property prior to the institution of the
Neuse Riparian rules. The shopping center is in a developed portion of the city. It
was reasonable for the owner to expect to be able to develop the remaining portion of
the shopping center. With zoning in place and conceptual plans prepared, the owner
entered into contract to sell the land for the expanded center for 1.7 million dollars.
The ability to expand the current center adds value to the property. Without the
expansion, not only is the value of the expansion lost, but the value of the existing
center is reduced.
ATTACHMENT TO VARIANCE REQUEST
Part 3: Protection of Water Quality
Water quality at Falls Village Shopping Center will be protected by a collection system
that gathers storm water and deposits the runoff in an engineered wetland. Also,
intensive landscaping along the perimeter of the project limits will aid in the treatment
of overland flow.
The collection system utilizes existing and proposed storm structures (catch basins and
drain inlets) to collect storm runoff and convey the water to the engineered wetland.
The water is released into the forebay of the wetland where the velocity is reduced
significantly, allowing the particulate matter to settle. The storm runoff then meanders
through the wetland and is released through an outlet structure. The treated water
enters the existing City of Raleigh storm drainage system and is eventually released to
Mine Creek. The wetland is designed according to the NCDENR manual,
"Stormwater Best Management Practices". A copy of the design is included in this
application.
Nitrogen compounds are found in a variety of forms in surface water. Some of the
compounds are not dissolved but rather adsorbed onto particulate matter. The
"tortuous path" provided by the engineered wetland allows settling to occur, 85% TSS
removal, thereby reducing the nitrogen load into the receiving body of water. Settling
the particulate matter has the added effect of removing metals and nonsoluble
pollutants as well.
The length of the flow path and the settling time provided by the wetland will have the
added benefit of increasing infiltration. The filtering action of soil and plants, and
biological activities in the soil, take up a variety of nutrients as stormwater moves
through the engineered wetland.
For dissolved nutrients, vegetation in the engineered wetland will be the focal point of
reducing inputs to surface water. The aquatic plants provide longer contact times with
pollutants, aid in the settling of particles that have pollutants adsorbed on them, and
greatly increase biological uptake as they consume dissolved nutrients through the
water. It is the case that the aquatic plants should be harvested periodically, usually in
the autumn after the plant has died, to prevent eutrophication and algal blooms as the
plant decays.
It should be of note that this project will improve water quality down stream. Prior to
the construction of this wetland, storm water from this drainage area was deposited in
the Neuse River Buffer directly. This project will route 33.4 acres of drainage through
an engineered wetland where previously no retention, detention, storage or treatment
of any kind was offered.

' HYDRAULIC CALCULATIONS
' All constructed wetlands have been sized to accommodate the 10 and 100-yr events. The
constructed wetlands will capture the first one (l) inch of runoff from the site and store that
volume for a minimum of two (2) days.
' HYDROLOGIC SOIL TYPES
' The geologic information concerning this site was obtained from the "Soil Survey of Wake
County, North Carolina" (US Department of Agriculture Soil Conservation Service). The
' drainage basin of this site is composed of both the Appling and the Cecil soil types (ApB,
CeC, and CeC2). The soil types are in hydrologic group "B". It is assumed the hydrologic
soil type is type "B", reflecting saturated conditions.
The existing drainage basin (33.4 acres) is composed of a shopping center, off site
apartments, off site residential with a 100-foot undisturbed buffer, and portions of an off site
golf course. The shopping center is assumed to be impervious except for the traffic islands
and landscaping. The apartment site is light residential as most of the contributing area has
vegetative cover. The residential area is wooded and the undisturbed buffer is thickly
wooded. The golf course has vegetative cover over most of the area.
In formulating the SCS curve number, a composite curve number was used (CN 86). The
Shopping Center comprises 52.5% of the drainage basin and has a CN of 98. The
apartment site comprises 7.8% of the drainage area and has a CN of 85. The golf course
comprises 29.8% of the drainage area and has a CN of 70. The wooded area makes up
9.8% of the drainage area and has a CN of 70. These numbers yield a composite curve
number of 86.

' SUMMARY OF PROCEDURE AND RESULTS
1
' GENERAL
• The proposed project will consist of constructing multiple 1-story buildings and two 2-story
' building additions within an existing shopping center. The project will have a total of
256,406 square feet of gross building area and approximately 436,800 square feet of
parking areas and drives.
• A portion of the site that is undeveloped and is proposed for development contains a
' Neuse River Basin Stream and associated buffers. As mitigation for disturbing the NRB
Stream Buffer the developer proposes to construct a storm water detention basin to trap
and settle out suspended solids in storm water runoff from a majority of the existing
' shopping center, all of the proposed shopping center addition, and offsite existing
development consisting of a country club and golf course, an apartment complex, and
single family subdivisions.
' The drainage area that will be treated consists of 33.37 developed acres (see attached
page). The on-site drainage is from the shopping center and is 52.5% (17.5 acres) of the
' total drainage area. The developer proposes to construct a "wet" pond in accordance
with the Stormwater Best Management Practices handbook of the North Carolina
Department of Environment and Natural Resources.
• The developer proposes to maintain an existing 100 foot wide natural buffer along the
north property line that will "filter" storm water runoff from existing developed single family
' subdivision lots.
METHODOLOGY
' • To model the detention pond the HydraflowTM "Hydrographs for Windows" by Intelisolve
software package was used.
' • This software created an inflow hydrograph based on drainage basin characteristics input
by the user.
' • The user also designed a reservoir, which was used as the basin of interest. The
inflow hydrograph was routed through the designed pond and the stage-storage, stage-
discharge and drainage characteristics were plotted.
RESULTS OF DETENTION BASIN SIZING AND STORM WATER ROUTING
9 Total drainage area = 33.7 acres
' On-site drainage area = 17.5 acres
• Developed peak run-off for 10-year event without storm water detention = 184.9 CFS
• Proposed peak run-off for 10-year event with storm water detention = 84.9 CFS
' • Developed peak run-off for 100-year event without storm water detention = 214.0 CFS
' • Proposed peak run-off for 100-year event with storm water detention = 87.3 CFS
• Detention basin designed to contain first 1 " of runoff and release in a 24-hour period.
' • Detention basin outlet structure to be a 30" reinforced concrete
pipe to an existing storm
system in Suburban Drive.
I
• 24-hour drawd own will be accomplished by infiltration into the soil and by the 4" orifice
' which will outlet at the normal water surface, into the structure.
' THE PROPOSED STORM WATER DETENTION POND WILL REMOVE >85% OF
SUSPENDED SOLIDS BY CAPTURING THE INITIAL 1- INCH OF STORM WATER RUNOFF,
DETAINING THAT VOLUME AND RELEASING IT OVER A 24-HOUR PERIOD.

BASIN CALCULATIONS
The detention basin for this site has been designed to comply with the manual for Stormwater
Best Management Practices for the North Carolina Department of Environment and Natural
Resources. The basin has been sized to accommodate the 10 and 100-year events. The
"wet basin will capture the first 1 " of runoff from the site and release it over a 24-hour
period. Additionally, the basin and outlet structure have been designed so that the post-
development peak flow from each basin is less than or equal to the pre-development peak
flow.
BASIN
• 1 " of Runoff: 1 " * Rv * 33.37 acres * 1 ft/12" = 1.91 acre feet = 83,200 cf
where: Rv = 0.05 + 0.009(1)
1 = 70 = percent impervious in drainage area

• Bottom Elevation of Pond: 412.00
Volume of Pond at Elevation 412.00: 147,712 cf
Since permanent pool is present, this volume is unusable for detention.
Usable Volume at Elevation 412.00: 0 cf
• Elevation of Pond at Structure Weir: 414.00
Volume of Pond at Elevation 414.00: 87,777 cf of usable volume
• Volume needed to store first 1 inch: 83,200 cf
Volume provided to store first 1 inch: 87,777 cf
• Required Surface Area = SA/DA
For a 5' deep permanent pool with 70% impervious surface, a percent SA/DA = 1.96%
Required Surface Area = (33.37)*(43560)*(0.0196) = 28, 772 SF for 85% TSS removal
Surface Area Provided (Elevation = 412.0) = 39,142 SF
• Drawdown over 24 period
87,777 cf / 24 hr * 1 hr/60min * 1 min/60 sec = 1.01 cfs

HYDROLOGIC SOIL TYPES
The geologic information concerning this site was obtained from the "Soil Survey of Wake
County, North Carolina" (US Department of Agriculture Soil Conservation Service). The
drainage basin of this site is composed of both the Appling and the Cecil soil types (ApB,
CeC, and CeC2). The soil types are in hydrologic group "B". It is assumed the hydrologic soil
type is type "B", reflecting saturated conditions.
The existing drainage basin (33.37 acres) is composed of a shopping center, off site
apartments, off site residential with a 100-foot undisturbed buffer, and portions of an off site
golf course. The shopping center is assumed to be impervious except for the traffic islands
and landscaping. The apartment site is light residential as most of the contributing area has
vegetative cover. The residential area is wooded and the undisturbed buffer is thickly wooded.
The golf course has vegetative cover over most of the area.
In formulating the SCS curve number, a composite curve number was used (CN 86). The
Shopping Center comprises 52.5%0 of the drainage basin and has a CN of 98. The
apartment site comprises 7.8% of the drainage area and has a CN of 85. The golf course
comprises 29.8% of the drainage area and has a CN of 70. The wooded area makes up
9.8% of the drainage area and has a CN of 70. These numbers yield a composite curve
number of 86.

Re: Falls Village Shopping Center Variance Request
Wake County
Dear Mr. Rice:
After reviewing the Variance request for the Falls Village Shopping Center there are
several items that could use some clarification. In the hydraulic calculations document it
appear that there is an error in the "volume to be stored" calculations. Also, I think it
would be helpful to clarify on the final plats to be sent to the EMC that the back of the
major retail building will be a retaining wall. As we discussed on the phone, I think you
need to strengthen your argument for uniqueness and hardship.
We will need 17 copies of the final variance request for the EMC and 2 more for our
office and the regional office. The 19 copies should be delivered to me by June 24 so I
can get them downtown. The plats should be reduced in number and size. If you would
like to meet and discuss these matters further, please feel free to call me at 733-1786.
Sincere .

As per your request, I am providing this memorandum to confirm that our client, Agora
Development, petitioner for the above referenced variance request, agrees with the EMC
approval condition as follows:
ACCEPTED CONDITION OF APPROVAL
The developer agrees not to pursue the commercial development of that portion of the

Dear Mr. Brooks:
Our firm is making application to the North Carolina Department of Environment and Natural

center is located at 6683 Falls of the Neuse Road in Raleigh, North Carolina. I am sending a copy
of the master plan and a portion of the USGS quadrangle with the location of the site highlighted.
We are providing you this information as part of the documentation process for the 401 permit.
Should you need any additional information or have any questions, please call me at 462-8474.

Re: Falls Village Shopping Center Variance Request
Wake County
Dear Mr. Rice:
As you are aware, the North Carolina Environmental Management Commission (EMC)
granted Agora Developments , LLC a variance from the Neuse River riparian buffer
rules (T15A. NCAC 2B .0233) for the proposed expansion of the Falls Village Shopping
Center at 6683 Falls of the Neuse Road in Raleigh. The variance was granted for the
proposed shopping center expansion and stormwater treatment as shown on the plats
dated May 11, 1999. The EMC also requested that a conservation easement be placed on
the remaining riparian buffers on the property to protect them from impacts in the future.
Agora Developments will now need to submit a completed Pre-construction Notification
(PCN) application for authorization under the US Army Corps of Engineers 404 permit
program and the Division's 401 water quality certification program. Along with the PCN
form to the State, you should include a payment of $475.00 for the 401 application fee
and the conservation easement that you propose for the remaining riparian buffer areas.
If you have any questions concerning this matter, please feel free to call Pete Colwell or
myself at 733-1786.
Sincerely,

Opening Comments
Chairman Peterson
1. Request for Approval of Recommendations from Tar-Pamlico Stakeholder Team Regarding
Voluntary Wetlands Restoration Actions - (Action Item) (Rich Gannon)
One of the Tar-Pamlico rule-making stakeholder teams that met over the winter of 1998 developed
recommendations regarding restoration activities to help achieve the basin's nutrient loading goals.
The recommendations included a request for the EMC to approve a voluntary restoration goal for
the basin, and to. establish the NC Wetland Restoration Program as lead agency and chair of a
technical committee that would facilitate attainment of that goal. This item was discussed at the
April WQC and May EMC meetings. In May, the EMC determined that the restoration
recommendations merited closer scrutiny, and agreed to have the WQC consider them in July.
Staff requests that the WQC approve the restoration stakeholder team's recommendations. Those
recommendations and supporting information are included in this package.
2. Request to Proceed to Notice of Text and to Public Hearings with Draft Tar-Pamlico Nutrient
Reduction Rules (Action Item) (Rich Gannon)
In May, the EMC directed staff to submit Notice of Rule-making Proceedings, or subject matter
notice, for draft Tar-Pamlico Nutrient Reduction rules. Draft rules developed by stakeholder teams
for agriculture, urban stormwater, nutrient management, and riparian buffer protection were to be
included in the Notice. In addition, the subject of atmospheric emissions of nitrogen was to be
included in the Notice. Staff will summarize comments received to date on the subject matter
notice, and will request approval from the WQC to proceed to the July EMC for approval to
publish notice of text and hold public hearings on the draft nutrient reduction rules. (Copies of the
draft rules are included in the EMC package.)
3. Request Permission to Send the Final Tar-Pamlico Basinwide Water Ouality Plan to the
EMC for Approval. - (Action Item) (Alan Clark)
DWQ staff will present the final draft Tar-Pamlico River Basinwide Water Quality Plan to the
Committee and request permission to take the plan to the Commission the following day for final
approval. NPDES permit renewals for this basin will commence in January 2000. The draft plan
was presented to the Committee in February 1999 and permission was granted to take the plan to
public meetings. Public meetings were held in Greenville and Rocky Mount in April 1999. A
number of comments were received and revisions were made to the final draft plans as necessary
based on these comments. (Copies of the plans with summaries of the public meetings and written
comments were sent to each EMC member in their EMC package.)
4. Consideration of a Request for a Variance From the Neuse River Riparian Area Protection
Rule - (Action Item) (Pete Colwell)
Agora Developments, L.L.C. proposes to add six new retail stores and associated parking to the
Falls Village Shopping Center at 6683 Falls of the Neuse Road in Raleigh. The existing shopping

8. Request Permission to Send the Draft Catawba River Basinwide Water Quality Plan to
Public Meetings. - (Action Item) (Darlene Kucken)
DWQ staff will present the draft Catawba River Basinwide Water Quality Plan to the Committee
and request permission to take the plan to public meetings in September. A final draft plan would
be developed based on public review comments. This final draft will be brought to the Committee
for final approval in December 1999 along with a request to present the plan to the full
Commission. (See enclosed copy of draft plan.)
9. Discussion of Division's Policies for Protection of Wetlands - (Information Item)(John
Dorney)
As of March 1, 1999, the Water Quality Staff has been using the water quality standards to address
recent large-scale wetland draining activities occurring in several eastern North Carolina counties.
Since announcing to the Water Quality Committee in February of this year the staffs intention to
enforce the Water Quality standards in these situations, there has been considerable controversy
about the issue. At the May EMC meeting, the staff was directed to bring this issue back to the
Water Quality for fin-ther discussion. Staff will present this as an information item.
10. Update on the City of High Point's Progress in Developing an Alternative Management
Strategy for High Density Development in the Randleman Lake Water Supply Watershed
(Information Item) - (Liz Kovasckitz)
The EMC approved rules in November of 1998 that established the proposed Randleman Lake
Water Supply Watershed as a Critical Water Supply Watershed pursuant to G.S. 143-214.5(b). The
rules also specified a nutrient management strategy for the watershed that included wastewater
discharge requirements, the protection and maintenance of riparian areas and stormwater control
requirements. The stormwater control requirements for the lower Randleman Lake watershed allow
local governments to develop alternative management strategies for the provisions in the High
Density Development Option of the rule, if they are determined by the Commission to provide
equal or greater water quality protection. The City of High Point developed a draft alternative
watershed management plan and requests this strategy be presented to the Water Quality
Committee for your consideration and comment prior to beginning their water supply watershed
protection ordinance development and public review process. Following this process, the City will
adopt, begin implementation and submit their ordinance to the Water Quality Committee for final
approval. Water supply watershed protection ordinances for Randleman Lake are due by January
1, 2000. (See attached information from the City of High Point.)

; h S z.e
6. Should reduce nutrients in watershed 40 - 50% . Should meet or exceed the
recommended N treatment for urban areas.
?I o 1 j ss 14.e6 - ?? ?? ? ii 41,rn ?
Staff Recommendation: 6't
Staff does not support the removal of riparian buffers for this kind of
development. However, there should be a net improvement in downstream
water quality because of the proposed stormwater treatment.
40
Mitigation under New Rules
1. Impacting - 45000sgft or 1.03 ac
2. Mitigation Required is 2.48 ac or 2160 linear feet of buffer
Zone 1 - 0.62 ac x 3 = 1.86ac
Zone 2 - 0.41 ac x 1.5= 0.62
3. Payment to Restoration Fund $103,223

Dear Mr. Colwell,
Attached you will find nineteen (19) copies of supplemental materials in support of our
variance request and nineteen (19) sets of reduced site plans. Also, we are including
three complete revised copies of the variance request. We had a typographic error in
the acreage of the drainage area in our support information. We have corrected this
error and added additional financial justification for our request.
If you have any questions, or need any additional materials, please call me and we
will promptly provide them.

Re: Falls Village Shopping Center
Proposed Redevelopment
Dear Mr. Colwell:
Thank you for taking time out of your busy schedule the other week to meet with me,
our soils scientist, and architect to walk the site and give us an opportunity to
introduce you to the existing site conditions and discuss development options. Based
on your input during the meeting and our previous meeting with you, Steve Mitchell,
and John Dorney we have modified our site plan to minimize the amount of Neuse
River Basin Stream Buffers (NRBSB) affected by the proposed development. Our
modifications include the following:
The storm water detention basin has been modified to include engineered
wetlands to provide removal of suspended particulate urban storm water pollutants
and dissolved nutrient uptake by the wetland plants in the proposed marsh areas.
2. The engineered detention/wetland area was reconfigured and relocated out of the
NRBSB area to minimize the disturbed area.
3. The proposed building located at the northwest corner of the site was moved to the
east to further minimize disturbance of the NRBSB. (The back side of the building
will serve as a retaining wall.)
4. The disturbance of the NRBSB has been reduced by more than 200 lineal feet
from our original plan submitted to you and your staff. (Total disturbed length of
NRBSB now proposed is less than 450 lineal feet.)
5. The landscaping of the site has been upgraded to provide additional buffers, trees,
and shrubs around the perimeter of the site and in the area of disturbance to

provide additional storm water filtering capability and dissolved nutrient
assimilation.
Attached you will find three (3) copies of our site plans showing the proposed site plan
improvements and three (3) copies of our storm water detention and engineered
wetland calculations.
Rice & Associates sincerely believes that the proposed treatment of the storm water
runoff from the shopping center and offsite developed areas will greatly improve
downstream water quality. Upon your concurrence that we have adequately
addressed your concerns we will provide you with an operation manual and a
maintenance agreement as part of the final package.
We request staff approval of the proposed improvements and that you place our
variance request on the agenda of the next Environmental Management Commission
meeting for consideration.
Rice & Associates appreciates your assistance and cooperation with this project and
we look forward to working with you.

FROM: Steve Rice
SUBJ: Falls Village Shopping Center - Neuse River Basin Stream Buffer Variance
EMC Water Quality Committee Approval of July 7, 1999
DATE: July 8, 1999
As per your request, I am providing this memorandum to confirm that our client, Agora
Development, petitioner for the above referenced variance request, agrees with the EMC
approval condition as follows:
ACCEPTED CONDITION OF APPROVAL
The developer agrees not to pursue the commercial development of that portion of the
proposed project which is currently zoned residential, but reserves the right to develop the
subject land as single family lots as long as the remaining undisturbed Neuse River Basin
Buffers within the residentially zoned land remain undisturbed. This restriction will serve as a
conservation easement for the mentioned riparian buffers.
