4. Proposed Activity U
..........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
Provide a detailed description of the proposed activity including its purpose and include the type of equipment to be used: *
The overall purpose of the Welcome Venture Park is to provide flexible space to accommodate industrial users that need office space,
warehousing, and light manufacturing, particularly in the initial phase of the project. The project will consist of approximately
1,300,000 square feet of light industrial & flex space. The building spaces are designed for those needing 4,000-10,000 sf of space.
The target end users are those in the Life Sciences field. The site is located within the Industrial Light and Residential zoning districts.
Most of the site will be rezoned to Industrial Light when the site is annexed into the City of Durham's corporate limits.
The location of the proposed project was chosen because it is located near Durham with close access to 185 and RTP. Additionally,
the site allows for access to existing utilities. Existing industrial and commercial operations are operating in the immediate area.
The future Northern Durham Parkway — Phase 2 will be permitted separately. Welcome Venture Park will be constructed in phases.
Phase 1 is planned to be constructed immediately, with future phases constructed after Northern Durham Parkway is completed.
Typical construction equipment will be utilized to complete the work.

Comments:
The proposed impacts are necessary for construction of a temporary perpendicular bridged crossing, SCM outfalls, and sewer
crossings. Modifications from the previous submittal include changes to impacts for the temporary road crossing and the addition of
SCM #2 outfall.
The proposed temporary bridged road crossing is necessary to access the developable uplands in the northwestern portion of the site
to source needed fill material for Phase 1. The road has been designed to cross Stream 1 perpendicularly and will span the entire
stream. The only impacts associated with the bridged road crossing are temporary buffer impacts (Zone 1: 2,281 sf, Zone 2: 1,533 sf).
The temporary road needs to be widened to accommodate side by side truck traffic.
Impacts for two non -perpendicular sewer crossings will result in 2,674 sf of permanent Zone 2 impacts. The two non -perpendicular
sewer crossings are only impacting Zone 2 and therefore are considered "Deemed Allowable" under (11)(II) in the Neuse Buffer Rules
and are being included here for clarity.
Two SCM outfall impacts are proposed. The outfall for SCM 1 will result in 827 sf of permanent buffer impacts (Zone 1: 479 sf; Zone
2: 348 sf). SCM 2 outfall will result in 622 sf of permanent buffer impacts (Zone 1: 276 sf; Zone 2: 346 sf). The outfall for SCM 2 is a
new impact and was not included on previous submittals. The SCM outfalls meet (9)(a)(i) in the Neuse Buffer Rules and therefore are
deemed allowable impacts. The outfalls are included in the attached exhibits and impact tables for reference.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and
"waters" could be minimized.
Buffer impacts have been minimized to only those necessary for a temporary bridge to access developable uplands in the
northwestern portion of the project, two sewer line impacts, and two SCM outfalls. The overall site has been designed to avoid
impacts to streams, wetlands, and buffers to the greatest extent practicable.
The temporary bridged stream crossing has been designed to cross Stream 1 at a perpendicular angle at a straight segment of
stream channel. This crossing will span the entire stream channel and no impacts to the stream will occur.
Upon completion of sewer line construction, impacts for the construction easement will be restored to pre -construction conditions and
grades, and temporarily stabilized with biodegradable matting and seeded to provide temporary stabilization until natural regeneration
of native vegetation permanently stabilizes the area.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Construction techniques used to avoid or minimize impacts include installation of erosion & sediment control devices prior to
construction activities and construction access occurring in high ground.
E. Diffuse Flow Plan
la. What type of SCM are you providing? *
Level Spreader
(] Vegetated Conveyance (lower SHWT)
O Wetland Swale (higher SHWT)
O Proposed project will not create concentrated stormwater flow through the buffer
O Other SCM that removed minimum of 30% nitrogen

1 b. Describe how diffuse flow will be maintained: *
The stormwater management plan for Welcome Venture development consists of seven constructed stormwater wetland SCMs which
provide a minimum of 30% nitrogen removal and therefore diffuse flow is not required. The stormwater management plan will be
reviewed and approved by the City of Durham as the certified municipality.
SCM's will outfall through dissipater pads to prevent erosion of riparian buffers.
