Impact Justification and Mitigation
1.
Avoidance and Minimization
1 a.
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
S&EC completed a wetland delineation and Neuse River Buffer evaluation for the entire property in order to identify
natural resources so that impacts could be avoided & minimized to the maximum extent practicable. Impact 1A is a
proposed road impact to Zones 1 & 2 of the Neuse riparian buffer. This impact is necessary to access the property from
an existing stub road from the west. The road alignment has been shifted to the north to avoid stream impacts and
minimized the riparian buffer impacts. In addition, a retaining wall has been utilized to minimize the riparian buffer
impacts. Impact 1B is proposed fill to a jurisdictional wetland. intermittent stream and riparian buffers for a road
crossing. This impact is proposing permanent and temporary wetland impacts (i e. 0. 044), 10 linear feet of temporary
stream impact (i.e. construction corridor) and 8linear feet of permanent, no permanent loss impact (i.e. riprap dissipater)
for a road crossing at the upper end of a stream system and headwater wetland. This impact is necessary to access the
southern portion of the northwestern section of the proposed subdivision. Headwalls have been utilized to minimize
wetland, stream and riparian buffer impacts Impact 2 is a proposed road crossing to an intermittent stream system and
riparian buffers. Proposed impacts include impacts to two streams, stream C was determined buffered. Impacts to stream
C includes 106 linear feet of permanent stream, 21 linear feet of temporary stream (i.e. construction corridor), 20 linear
feet of permanent -no permanent loss stream impact (i.e. riprap dissipater) and associated riparian buffer impacts. Stream
Z includes 76 linear feet of permanent stream impact (i.e. non -buffered stream). Headwalls and retaining walls have been
utilized to minimize stream and riparian buffer impacts. This impact is necessary to access the southern portions of the
proposed subdivision. Impact 3 are proposed wetland impacts necessary for a road and lot fill. These impacts are
cumulatively proposing 0.035 acres of wetland fill. These impacts are necessary because the City of Durham requires a
street stub in this location; therefore wetland impacts for the road are unavoidable. Additionally, this project will require
mass grading, which is necessary to control the direction of post -construction stormwater flow.
Furthermore, the applicant is aware of the regional conditions associated with the Nationwide Permits 29. With
respect to residential development conditions (NWP 29 -Regional Conditions section 4.0) the applicant does not
anticipate any impacts to streams or wetlands associated with stormwater facilities, there are no impacts associated
with single-family recreation facilities, there are no permanent wetland or stream fills proposed within the
floodway/floodplain and the stream classification for this project is C, NSW (i.e. not Outstanding Resource Waters,
High Quality Waters, Coastal Wetlands or wetland adjacent to these waters) and riprap stabilization is not anticipated.
1 b.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
As per the project engineer. Standard Erosion Control measures will be incorporated during construction including
but not limited to sediment riser basins, silt fencing and outlets, diversion ditches and storm structure inlet
protection. Bypass pumping will be utilized where necessary to maintain construction in the dry (see sheet IE5).

additional development, which could impact nearby downstream water quality?
3b.
if you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWO policy. 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
Courtyards at Andrews Chapel project is a residential development. Additionally, the project is located within the City of
Durham jurisdiction, 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 to "diffuse flow" requirements and
Best Management Practices that control nitrogen if diffuse flow cannot be achieved, and 2) the Phase 11 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.
4.
Sewage Disposal (DWQ Requirement)
