Re: Tree Farm Subdivision - Starterwood Lane (Phase 3)
PIN, 9853-20-3133 Orange County, NC
Stormwater Management Plan Revision
Neuse Buffer Rules Authorization
DWQ Project # 05-0172
Dear Brianne:
On February 18, 2009 your firm submitted revisions to the stormwater management
plan for Starterwood Lane under construction in Tree Farm Subdivision. Tree Farm is a
low-density (10+ acre lot size) residential development. Starterwood Lane is a private
roadway that serves lots in phase 3 of the subdivision. The road included a stream
crossing of an unnamed tributary to Crabtree Creek located within the Neuse River
basin.
The 401 Water Quality Certification was issued for the crossing by the North Carolina
Division of Water Quality (DWQ) on February 13, 2008. That approval included the use
of level spreaders to meet the diffuse flow requirement under the Neuse Buffer rules.
However, during an onsite meeting on February 17, 2009 your firm and the developer
expressed feasibility concerns with the proposed level spreaders. As a result, we
agreed to consider an alternative design to meet the diffuse flow requirement to protect
the stream buffer.
The revised stormwater plan includes the use of a series of "diversion spreaders" that
will turn out runoff to stable, forested ground through a trapezoidal shaped swale
designed pursuant to DWQ's stormwater BMP manual. This will reduce the amount of
water flowing through the roadside ditches that discharge to the stream. Since this was

a new concept, we discussed the proposed revisions with Ms. Annette Lucas,
Stormwater Engineer with DWQ's 401 permitting section. She concurred that the
concept should function to meet the regulatory requirements of diffuse flow. Thus, the
County as local delegated authority under the Neuse rules, approves the proposed
revision in the stormwater management plan.
Specifically, you have been granted approval, in accordance with the conditions listed
below, to install "diversion spreaders" rather than level spreaders to meet the diffuse
flow requirement under the Neuse Buffer rules.
This approval is only valid for the purpose and design described in your submittal dated
February 18, 2009. Any change to the project requires notification to our Office and
may require submittal of a new application. If ownership of the property is transferred to
another person(s) or entity, the new owner(s) will be responsible for complying with all
conditions of approval. You are required to supply a copy of this approval letter to the
new owner as well. For this approval to be valid, you must follow the conditions listed
below as well as any other conditions identified within 15A NCAC 2B .0233.
Conditions:
1. Modify the Road Maintenance Agreement to include maintenance and operation
of the proposed diversion spreaders. Provide a copy of the recorded agreement
to our office for our files.
2. Our office intends to make periodic inspections to observe how the diversion
spreaders are functioning. However, we are requesting that the developer
monitor the effectiveness of the diversion spreaders. Monitoring will consist of the
following:
a. Inspect the diversion spreaders quarterly for the first year after they are
constructed. At least one of the inspections must be conducted during a
rainfall event of 0.5 inches or greater.
b. After each inspection provide a simple email report documenting the
condition of the diversion spreaders; this should include date of inspection,
whether erosion is observed, stability of the vegetation, maintenance (if
necessary) and supporting photographs.
c. After one year the diversion spreaders should be inspected annually as
part of the routine maintenance described above.
If you do not accept any of the conditions of this approval, you may ask for an
adjudicatory hearing. You must act within 60 days of the date that you receive this letter.
To ask for a hearing, send a written petition, which conforms to Chapter 150B of the
North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box
27447, Raleigh, N.C. 27611-7447. This approval and its conditions are final and binding
unless you ask for a hearing.
