1.4. Describe your system, in narrative, identifying use of pipe, open channels, to give a
general feel for how the system performs and the general condition of the streams and
other water bodies receiving runoff.
The Chapel Hill storm sewer system is a combination of open channel and closed channel.
Stormwater is conveyed to receiving streams by a combination of overland flow, swales
and open channels, pipes, culverts, and bridges.
The major receiving streams to which stormwater discharges are Bolin Creek, Booker
Creek, Little Creek, and Morgan Creek.
Using summer interns, a portion of the stormwater conveyance infrastructure was
previously field located and mapped using the Town's Geographic Information System. .
Under average conditions, the Town's stormwater management systems perform
adequately in containing and conveying stormwater runoff. Localized drainage problems
periodically occur in some locations under certain conditions due to inadequate or
deteriorated conveyance facilities. During large storm events, culverts and streams in the
lower segments of the Town's watersheds periodically flood as a result of high volumes of
runoff in conjunction with low flow velocity (gradient) in these areas of Town.
Some of the Town's perennial and intermittent streams have been listed as impaired on
North Carolina's §303(d) list. Most pollution in Chapel Hill streams is a result of
sedimentation and non-specific pollution from urban runoff and storm sewers.
Maintenance of the stormwater system located within the Town's rights -of -way is
performed by staff in the Stormwater Management Division. Seven full-time staff are now
dedicated to this function.
Bridges and road crossings are inspected biennially and after significant storm events.
Other drainage system components are not inspected on a routine basis but are evaluated
on a site -specific basis in response to complaints and/or observed problems.
Maintenance is performed on an as -needed basis in response to functional problems,
using a combination of hand -tools and small power equipment, pressure -flushing, and/or
jet -vacuuming as appropriate.

3. EXISTING WATER QUALITY PROGRAMS
0 3.1 Local Programs .
• Water Supply Watershed Protection Program
Section 3.6.4 of the Chapel Hill Land Use Management Ordinance carried over the
Watershed Protection District from the Town's Development Ordinance. Its purpose is
to provide long-term water quality protection of the watershed that drains into Jordan
Lake Reservoir, a drinking water source. The area of the Watershed Protection District
extends five miles from the normal pool elevation of Jordan Lake Reservoir or the
ridgeline of the watershed, whichever is less. This program includes water quality
requirements for high density development and stream buffer requirements.
• Stormwater Management
Section 5.4 of the Chapel Hill Land Use Management Ordinance specifies the
stormwater management requirements, including a water quality regulation, for all
development that adds impervious area. This section states that "stormwater treatment
shall be designed to achieve average annual eighty-five (85) per cent total suspended
solids (TSS) removal and must apply to the volume of post -development runoff resulting
from the first one -inch of precipitation."
• Erosion and Sediment Control
Article V of Chapter 5 contains the Town's Erosion and Sediment Control Ordinance.
For land development projects disturbing 20,000 square feet or more of land, an erosion
and sediment control permit is required. The program is administered by the Orange
County Erosion Control Division.
• Steep Slopes
Section 5.3, Critical Areas and Environmental Performance Standards, of the Chapel Hill
Land Use Management Ordinance cross references the Town's Erosion and Sediment
Control Ordinance and establishes limitations on the development of steep slope areas
and construction techniques.
• Resource Conservation District
Section 3.6.3 of the Chapel Hill Land Use Management Ordinance established stream
buffers along all perennial streams. intermittent streams, and perennial waterbodies
within the Town's planning jurisdiction in order to preserve the water quality of the
Town's actual or potential water supply sources, to minimize danger to lives and
properties from flooding in and near the watercourses to preserve the water -carrying
capacity of the watercourses, and to protect them from erosion and sedimentation, to
retain open spaces and greenways and to protect their environmentally -sensitive
character, to preserve urban wildlife and plant life habitats from the intrusions of
urbanization, to provide air and noise buffers to ameliorate the effects of development,
and to preserve and maintain the aesthetic qualities and appearance of the Town.
• Tree Protection
Section 5.7 of the Chapel Hill Land Use Management Ordinance regulates the
protection, installation, removal, and long-term management of trees, shrubs and soils in
Chapel Hill and its extraterritorial jurisdiction.

Long Range Transit
Continue long-range transit planning.
Community, Town staff
Completion of Long Range
Planning
The transportation goal in the 2000
Transit Plan
Comprehensive Plan includes the
enhancement of a balanced, multi -modal
transportation system that will improve
mobility for all citizens, reduce automobile
dependence, and preserve/enhance the
character of Chapel Hill. To do this, the
Town wishes to increase the use of public
transportation so that new development
can be accommodated without the need
for major expansion of the existing arterial
road network.
A major component to reach this goal is
the preparation of a Long Range Transit
Master Plan for the Chapel Hill Transit
Partners, encompassing the Town of
Chapel Hill, Town of Carrboro and the
University of North Carolina at Chapel Hill.
On June 26, 2006 the Town Council
approved a proposed request for
qualifications to seek consultants to assist
in preparing a Long Range Transit Master
Plan. In.particular, the Plan will focus on
the transportation needs of the Carolina
North development project that is being
planned by the University of North
Carolina.
The purpose of the Long Range Transit
Town of Chapel Hill Page 36
NPDES Permit Renewal Application

Plan is to support the continued
development of regional transportation
plans. The Long Range Transit Plan is
intended to inform the ongoing process of
preparing the 2035 Long Range
Transportation Plan by providing more
detailed identification and analysis of
transit alternatives. The development of
the 2035 Long Range Transportation Plan
will address broader issues of new or
expanded roadways and related
transportation improvements.
Sustainability
Continue sustainability initiatives. Please
Community, Town staff
description of Sustainability programs
below.
The Town of Chapel Hill is committed to the sustainability of our community. Qualified as a Sierra Club "Cool City" by the U.S. Council
of Mayors, we have set a goal of reducing carbon emissions 60 percent below 2005 levels by 2050. We have joined the Cities for
Climate Protection Campaign, a program sponsored by the International Council of Local Environmental Initiatives (ICLEI), and work
with Carrboro, Hillsborough, and Orange County to reduce regional greenhouse gas emissions.
The Town's Comprehensive Plan is the centerpiece of policies that promote compact, mixed -use development, alternative
transportation, greenway development, and environmental protection. Each of these measures is aimed toward minimizing fossil fuel
dependency, thereby reducing greenhouse gas emissions and their contribution to global warming.
In 2007, the Town formed the Sustainability Committee, to be made up of citizens interested in developing a sustainability plan for the
community and carrying out education and outreach activities. The Town's Sustainability, Energy, and Environment (SEE) Committee
is made up of Council Members who develop and support sustainability policies and programs. The SEE Committee's work has led to
Town policies which encourage developers to address energy efficiency and alternative energy in their projects, and which provides
incentives for developers seeking to "build green".
The Town has a bond -supported revolving loan fund, called the "Energy Bank," to promote installation of energy efficient equipment in
Town -owned buildings. This acts like a revolving loan fund and provides financial assistance for departments wishing to undertake
such projects. Money saved on utilities is put back into the "Energy Bank" to fund similar projects in the future.

We are also committed to purchasing environmentally sensitive products, including biofuel and hybrid vehicles for our municipal fleet.
We've ensured that all Town buildings built after 2005 are outstanding examples of sustainable building practices, such as those
prescribed by the LEED "Silver" certification program. A good example of this is the Town Operations Center, which opened in
September 2007. The $52 million Town Operations Center project reflects the Council's key values of sustainability, environmental
sensitivity and fiscal prudence. The project includes a geothermal heating system, underground tanks to hold rainwater for flushing
toilets and irrigation, and passive and active solar design feature of daylighting.
SUSTAINABILITY POLICIES AND PROGRAMS
• Carbon Reduction Program
In 2006, the Town of Chapel Hill became the first U.S. municipality to commit to a 60 percent reduction in carbon dioxide emissions by
2050 through the Carbon Reduction Program. The Council authorized the pledge to reduce carbon dioxide emissions from Town
municipal operations on a per capita basis, beginning with an initial goal of 5 percent reduction by 2010.
• LEED-Based Energy Ordinance
Any new or expanded building constructed by and for the town and meeting the applicability criteria in Section 5-123 shall employ the
Leadership in Energy and Environmental Design (LEED) Green Building Rating System throughout their design, construction, and
operation unless the town council determines that such certification is not in keeping with the use or purpose of the building or is
otherwise inappropriate. The LEED Green Building Rating System refers to the most recent version of the Leadership in Energy and
Environmental Design (LEED) Commercial Green Building Rating System, or other related LEED Rating System, approved by the
U.S. Green Building Council. Read more about the LEED-Based Energy Ordinance.
• Joint Chapel Hill-Carrboro-Orange County Greenhouse Gas Emissions Inventory and Reduction Plan
This plan is part of ICLEI's Cities for Climate Protection Campaign. Read more about the Memorandum of Agreement for the Joint
Chapel Hill-Carrboro-Orange County Greenhouse Gas Emissions Inventory and Reduction Plan.
• Energy Bank
In the November 4, 2003, bond referendum, the citizens of the Town of Chapel Hill voted in favor of a $500,000 (current balance is
$475,000) bond for creation of an Energy Bank. The purpose of these bond funds is to acquire, construct, equip and install energy
efficient facilities in certain existing public buildings, including, without limitation, the acquisition of lighting, heating, ventilating, air
conditioning and related fixtures, machinery and equipment. It is envisioned that the documented savings attributable to projects
completed with these funds will be used to reimburse the fund for the cost of the project. Energy Bank Policies and Procedures

• Renewable Energy Planning in Rezoning Applications
It is the expectation of the Council that applicants seeking approval of conditional use rezoning with accompanying special use
permits will demonstrate site planning, landscaping, and structure design which maximize the potential for energy conservation and
use of renewable energy by reducing the demand for artificial heating, cooling, ventilation, and lighting, and facilitating the use of solar
and other energy resources. The Council expanded this policy in April 2007 to encourage applicants to include a "20 percent more
energy efficient" feature in their development plans.

• Resource Conservation District
In 1985, Chapel Hill established the Resource Conservation District as an overlay zoning district. Underlying general -use zoning (e.g.,
Residential-1, Neighborhood Commercial, etc.) establishes what uses are permitted on a property, along with dimensional standards
for structures. Overlay zones, such as the Historic Districts, Airport Hazard District, and Resource Conservation District, place
additional restrictions on properties because of special considerations.
In the case of the Resource Conservation District, those special considerations are the protection of stream corridors and prevention
of property damage from floods. RCD regulations were significantly modified on January 27, 2003, with the adoption of the new Land
Use Management Ordinance.
• Watershed Protection District
The Watershed Protection District iss-a sensitive area of land that drains to Jordan Lake Reservoir, a drinking water source for
thousands of North Carolinians, and a potential future drinking water source for Chapel Hill. As part of the NC Division of Water
Quality's Water Supply Watershed Development Regulations, land use within this area has strict requirements for density, Resource
Conservation Districts, use of toxic materials, and construction standards.
• Protecting Trees in Chapel Hill
The Council has initiated proposed changes to the Tree Protection Ordinance that would establish a new vision statement that calls
for no net loss of trees/canopy cover and an increase in trees proportional to population growth. Regulations propose a permitting
process for tree removal on private property, including residential. The first step of the phased proposal would require a permit to
remove trees in a cumulative area of more than 5,000 square feet. Changes are also proposed to lower the threshold size of trees
that must be surveyed. The ordinance revision is linked to a Townwide commitment to sustainability with the potential to reduce
carbon emissions and decrease the urban "heat-island" effect.
Fare Free Transit
In January 2002, Chapel Hill Transit began providing fare -free bus services to the Chapel Hill-Carrboro-University community. Chapel
Hill created a Town -operated bus service in 1974 in response to increased concerns about traffic on Town streets, inadequacy of
parking at the University and UNC Hospitals, and environmental issues. The University contracted with Chapel Hill to help support the
system and has been a partner in the operation for the past 30 years. Carrboro joined the partnership in 1977 and has participated
continuously since that time.
• Green Fleets Policy
The Council established a Green Fleets Policy in 2005 that requires the Town to obtain energy efficient vehicles and to operate its
fleets in a manner that is energy efficient and minimizes emissions. The Town endeavors to decrease energy expenditures for its
fleets by 3 percent at the end of 2007-08. The policy expresses the Council's commitment to reducing energy consumption and
dependence on foreign oil, and to improving air quality.
• Town Creates Economic Development Officer Position (April 2007)
Town of Chapel Hill Page 19

• • s
The economic development officer works with the Town Manager and Council to develop a clear economic development strategy
using the Town's adopted plans; works with the Town Manager and staff to seek improvements in the Town's development process
that maintain excellent results; and identifies potential projects and begin conversations to forge redevelopment.
• Rural Buffer
An area surrounding Chapel Hill and Carrboro that will remain at lower density. The Rural Buffer defines the urban services boundary
and the limit of Chapel Hill and Carrboro's growth.
• Chapel Hill ETS Planning Jurisdiction
This area is subject to Chapel Hilt's Land Use Management Ordinance for development activities.
• Go! Chapel Hill Active Living
Go! Chapel Hill Active Living by Design is a program that the Town of Chapel Hill has adopted to encourage "Active Living by Design."
The program promotes active living in schools, neighborhoods and businesses. The program recognizes the link between the
pedestrian and bicycle mobility and the increasing trend -of obesity in the American population.
• Town Sustainability Committee
A permanent Town committee was established in May 2007 to address all forms of renewable energy and energy efficiency.
