E. Impact Justification and Mitigation
1. Avoidance and Minimization
U

1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
S&EC completed a wetland delineation and Neuse River Buffer evaluation for the entire property to identify natural resources so that impacts could be
avoided and minimized to the maximum extent practicable. Impact 1A is proposed permanent -no permanent loss wetland impacts for a utility crossing.
The crossing will occur perpendicular at the narrowest portion of the wetland to minimize wetland impacts and tie into the existing utility easement that is
located west of the crossing. Compensatory mitigation @ 1:1 ratio has been proposed to offset permanent wetland impacts. Impact 1 B is proposed
permanent -no permanent loss wetland impacts and permanent zone 1 buffer impacts for a utility crossing. This crossing is necessary to tie into the
existing utility easement to the north. The crossing has been placed as far west of the stream to avoid any stream impacts and most zone 1 buffer
impacts. Per the Neuse River Buffer Rules (15a ncac 02b .0714 (ll(i)), the Zone 2 buffer impacts have been determined "deemed allowable'.
Compensatory mitigation @ 1:1 ratio has been proposed to offset permanent wetland impacts. Impact 2 is proposed permanent and temporary stream
impacts for a road crossing. The road crossing will cross the stream at a perpendicular angle near the top of the drainage and is necessary to access a
portion of the northwestern development. A retaining wall is being utilized to minimize stream impacts to the maximum extent practicable. The location of
the crossing is necessary as the City of Durham requires interconnectivity and minimum radii on the corners. Compensatory mitigation @ 2:1 ratio is
being proposed to offset permanent stream impacts. Impact 3A is proposed permanent and temporary stream impacts for an underground storm pipe. A
retaining wall is being utilized to minimize stream impacts. This impact is necessary as the City of Durham requires that all impervious area is captured
and directed toward a stormwater control measure (SCM). Compensatory mitigation @ 2:1 ratio is being proposed to offset permanent stream impacts.
Impact 3B is proposed permanent, permanent -no permanent loss, and temporary stream impacts for a utility crossing. This utility crossing is necessary
to connect sanitary sewer to the southwestern portion of the project and will cross the stream at a perpendicular angle to minimize stream impacts. A
retaining wall and riprap dissipator will be utilized to reduce flow velocities and minimize stream degradation. Compensatory mitigation @ 2:1 ratio is
being proposed to offset permanent stream impacts. Impact 4A is proposed permanent stream impacts for a road crossing. This impact is necessary to
provide a cul-de-sac to access lots. The location of this impact is occurring at the top of the drainage and is located near a stormwater and sewer
easement. This area is designed at the maximum slope allowed by the City of Durham. Compensatory mitigation @ 2:1 ratio is being proposed to offset
permanent stream impacts. Impact 4B is proposed permanent stream impacts for an underground storm pipe. This pipe will cross the stream at a
perpendicular angle to minimize stream impacts. This impact is necessary as the City of Durham requires that all impervious area is captured and
directed toward a stormwater control measure (SCM). Compensatory mitigation @ 2:1 ratio is being proposed to offset permanent stream impacts.
Impact 4C is proposed permanent and temporary stream impacts for a utility crossing. This utility crossing will cross the stream at a perpendicular angle
to minimize stream impacts. A retaining wall will be utilized to minimize stream impacts. Compensatory mitigation @ 2:1 ratio is being proposed to offset
permanent stream impacts. Impact 5 is proposed permanent, permanent -no permanent loss, and temporary stream impacts as well as permanent buffer
impacts for a road crossing. This crossing is necessary to connect the northern portion of the development with the southern portion. The road crossing
will occur perpendicular to the stream and utilize retaining walls to minimize impacts to the maximum extent practicable. A riprap dissipator will be
utilized at the end of the culvert to reduce flow velocities and minimize stream degradation. Compensatory mitigation @ 2:1 ratio is being proposed to
offset permanent stream impacts. Impact 6A is proposed permanent and temporary stream impacts for an underground storm pipe. The pipe will cross
the stream at a perpendicular angle to minimize stream impacts. As previously stated, this impact is necessary as the City requires that all impervious
area is captured and directed toward a stormwater control measure (SCM). Compensatory mitigation @ 2:1 ratio is being proposed to offset permanent
stream impacts. Impact 6B is proposed permanent, permanent -no permanent loss, and temporary stream impacts for a utility crossing. The utility will
cross at the stream at a perpendicular angle and utilize a riprap dissipator to reduce flow velocities and minimize stream degradation. Compensatory
mitigation @ 2:1 ratio is being proposed to offset permanent stream impacts. Impact 7 is proposed temporary stream impacts for a utility crossing. Per
the Neuse River Buffer rules, (15a ncac 02b .0714 (kk(i)), the buffer impacts for this crossing are considered "deemed allowable". The crossing will occur
at a perpendicular angle with the stream to minimize stream impacts to the maximum extent practicable. Impact 8 is proposed permanent and temporary
wetland impacts, permanent and permanent -no permanent loss open water impacts, and permanent buffer impacts for a road crossing. This road
crossing is necessary to connect the entire eastern and western portions of the development. The crossing will occur perpendicular to the open water
(i.e. beaver impoundment) and utilize retaining walls to minimize impacts to the maximum extent practicable. Three box culverts will be utilized for
connectivity and allow for continuous flow of water. It should also be noted that this crossing is occurring at the narrowest portion of the open water and
avoids any stream impacts to the north. The crossing was considered to be placed further to the south, however, a culvert crossing in this location would
create off -site impacts to the flood elevations to the upstream properties. For velocity dissipation, permanent turf reinforcement matting will be installed
on the outlet side of the box culverts. Per the project engineers, the proposed turf reinforcement matting will provide the necessary velocity dissipation,
erosion control benefits, and reduction of scour required, but will still allow the natural wetland functions that benefit water quality to occur. Specifically,
turf matting is porous and allows water to travel freely through to the subgrade below. This will allow the wetland to function properly in the wetting and
drying cycle by allowing water to enter the soil profile when the water table is low or between storm events as necessary to allow for the removal of
harmful bacteria. Also, because the material is porous, it will allow water to travel into the soil profile after storm events allowing for saturation. During
this period of saturation, denitrification will occur within the soil profile just as in a natural wetland. And finally, the turf matting will help to reduce velocity
by providing a higher roughness coefficient. This will slow the water down and promote sedimentation. This will help to remove sediment particles and
attached phosphorus just as in a natural wetland. Turf matting also allows for vegetation to grow through the mat providing additional support for the
vegetation. The vegetation will absorb and store nitrogen and phosphorus within their structure just as in a natural wetland. Compensatory mitigation @
2:1 ratio is being proposed to offset permanent wetland impacts. Compensatory mitigation @ 3:1 for Zone 1 buffer impacts and @ 1.5:1 for Zone 2 buffer
impacts is also being proposed to offset permanent buffer impacts. Impact 9 is proposed permanent -no permanent loss wetland impacts and temporary
open water impacts for a utility crossing. The crossing will occur perpendicular to the open water and the proposed road crossing to minimize impacts to
the maximum extent practicable. Per the Neuse River Buffer rules, (15a ncac 02b .0714 (kk(i)), the buffer impacts for this crossing are considered
"deemed allowable". Compensatory mitigation @ a 1:1 ratio for permanent -no permanent loss impacts will be proposed to offset wetland impacts. Impact
10 is proposed zone 2 buffer impacts for a utility crossing. This crossing is occurring parallel to the stream and was designed to avoid any Zone 1 buffer
impacts. Per the Neuse River Buffer Rules (15a ncac 02b .0714 (ll(i)), the Zone 2 buffer impacts have been determined "deemed allowable'. Impact 11A
is proposed temporary stream and permanent -no permanent loss wetland impacts for a utility crossing. The crossing will occur perpendicular to the
stream to minimize impacts. Per the Neuse River Buffer rules, (15a ncac 02b .0714 (kk(i)), the buffer impacts for this crossing are considered "deemed
allowable'. Compensatory mitigation @ a 1:1 ratio for permanent -no permanent loss impacts will be proposed to offset wetland impacts. Impact 11 B is
proposed zone 2 buffer impacts for a utility crossing. This crossing is occurring parallel to the stream and was designed to avoid any Zone 1 buffer
impacts. Per the Neuse River Buffer Rules (15a ncac 02b .0714 (II(i)), the Zone 2 buffer impacts have been determined "deemed allowable'. Impact 12 is
proposed permanent, permanent -no permanent loss, and temporary stream impacts as well as permanent buffer impacts for a road crossing. This
crossing is necessary to connect the northeastern portion of the development with the southeastern portion. The road crossing will occur perpendicular
to the stream and utilize retaining walls to minimize impacts to the maximum extent practicable. A riprap dissipator will be utilized at the end of the
culvert to reduce flow velocities and minimize stream degradation. Compensatory mitigation @ 2:1 ratio is being proposed to offset permanent stream
impacts. Impact 13 is proposed temporary stream and permanent buffer impacts for a utility crossing. This crossing is necessary to connect to the
proposed sewer line to the existing pump station to the north. The crossing will occur at a perpendicular angle with the stream and will utilize temporary
silt bags, temporary pump around, and temporary impervious dike to minimize stream impacts during construction activities.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Measures being taken to avoid/minimize proposed impacts through construction techniques include coffer dams during the culvert installation and pump
arounds to ensure the stream baseflow is safely routed around the construction site. Dewatering pumps will remove water from the construction area
and discharge it to silt bags. Silt fencing will be utilized and placed downstream of all other disturbed areas to ensure no sediment laden water escapes
the construction area.

3c. Comments
S&EC reviewed the NCDWR Approved mitigation banks in NC list, there were five (5) banks listed within the HUC 03020201 that had riparian wetland,
buffers, and/or stream credits available. All five (5) were contacted, one had all the buffer and wetland credits available. Only one other bank had a
portion of the stream credits we needed available. Permanent wetland loss impact = 0.088 acres; 0.088 @ 2:1 mitigation ratio = 0.176 acres,
Permanent -No Permanent wetland loss = 0.219 @ 1:1 mitigation ratio = 0.219 acres, Total = 0.176 acres + 0.219 acres = 0.395 acres.
Total permanent stream loss = 620 LF @ 2:1 ratio = 1,240 LF.

G. Supplementary Information
1. Environmental Documentation
No
1a. Does the project involve an expenditure of public (federallstatellocal) funds or the use of public (federal/state) land? *
Yes No
2. Violations (DWR Requirement)
2a. Is the site in violation of DWR Water Quality Certification Rules (15A NCAC 2H .0500), Isolated Wetland Rules (I SA NCAC 2H .1300), or DWR Surface Water or Wetland Standards or
Riparian Buffer Rules (15A NCAC 2B .0200)? *
Yes No
3. Cumulative Impacts (DWR Requirement)
3a. Will this project result in additional development, which could impact nearby downstream water quality?
Yes No
3b. If you answered "no," provide a short narrative description.
We have reviewed the "Draft Internal Policy, Cumulative impacts and the 401 Water Quality Certification and Isolated Wetlands Programs" document
prepared by the NC Division of Water Quality on April 10, 2004, version 2.1. The draft states that many private developments are unlikely to cause
cumulative impacts, including projects such as urban in -fill, most residential subdivisions and small commercial developments as well as agricultural and
silvicultural operations. The Solana project is a residential development. Additionally, the project is located within the City of Durham ETJ, therefore the
adjacent properties that have potential for development will have the following regulations to protect downstream waters: 1) the Neuse River Basin
Riparian Buffer Protection regulations, these regulations require limited development within the riparian buffer area, in addition Best Management
Practices may be required that control nitrogen if diffuse flow cannot be achieved; 2) the Water Supply, Watershed Protection Program which limits
development densities as well as requires protective riparian buffers; 3) the Phase II NPDES Stormwater Permit Program, this program includes
permitting requirements for Municipal Separate Storm Sewer Systems (MS4s) in addition to post -construction stormwater management requirements.
We anticipate that the DWR will advise us if any additional information is needed.
