WATERSHED REGULATIONS
Section 7-1 General
7-1.1 Jurisdiction
The provisions of these regulations shall apply within the area designated as a
Public Water Supply Watershed by the North Carolina Environmental
Management Commission and shall be defined and established on the map
entitled, "Watershed Protection Map" which is adopted simultaneously herewith.
The watershed map and all explanatory matter contained thereon accompanies and
is hereby made a part of these regulations.
7-1.2 Authority
These watershed regulations are adopted and enforced pursuant to G.S. 160A,
Article 19, Planning and Regulations (see also Article I, Section 1) and G.S.
143214.5 Water Supply and Watershed Protection.
7-1.3 Adoption and Effective Date
The Water Supply Watershed Protection Regulations were duly adopted September
13, 1993 by the Town Council of Jonesville, North Carolina. These amendments to
the Jonesville Zoning Ordinance shall be effective October 1, 1993.
7-1.4 Exceptions to Regulations
(a) Existing development, as defined in Section 7-2 Definitions, is not subject
to the requirements of these regulations. Expansions to structures
classified as existing development must meet the requirements of these
regulations, however, the built-upon area of the existing development is
not required to be included in the density calculations.
(b) A pre-existing lot owned by an individual prior to the effective date of
these regulations, regardless of whether or not a vested right has been
established, may be developed for single-family residential purposes
without being subject to the restrictions of these regulations.
7-1.5 Criminal Penalties
In addition to the penalties imposed by Section 14-3 of the Jonesville Zoning
Ordinance, the North Carolina Environmental Management Commission may
assess civil penalties in accordance with G.S. 143-215.6(a). Each day that the

Section 7-2 Definitions
The following definitions apply specifically to the watershed overlay districts.
Agricultural Use. The use of waters for stock watering, irrigation, and other farm purposes.
Animal Units. A unit of measurement developed by the U.S. Environmental Protection Agency
that is used to compare different types of animal operations. One hundred animal units equates to
70 dairy cows, 100 beef cattle, 250 hogs, 50 horses, 1,000 sheep, 5,500 turkeys, 3,000 chickens
with liquid manure systems, 10,000 chickens with continuous overflow waterers, or 500 ducks.
Best Management Practices (BMP's). A structural or nonstructural management-based practice
used singularly or in combination to reduce nonpoint source inputs to receiving waters in order to
achieve water quality protection goals.
Buffer (watershed). An area of natural or planted vegetation through which stormwater runoff
flows in a diffuse manner so that the runoff does not become channelized and which provides for
infiltration of the runoff and filtering of pollutants. The buffer is measured landward from the
normal pool elevation of impounded structures and from the bank of each side of streams or
rivers.
Built-upon Area (impervious area). Built-upon areas shall include that portion of a development
project that is covered by impervious or partially impervious cover including buildings, pavement,
gravel roads, recreation facilities (e.g. tennis courts), etc. (Note: wooden slatted decks and the
water area of a swimming pool are considered pervious.)
Cluster Development. The grouping of buildings in order to conserve land resources and provide
for innovation in the design of the project. This term includes non-residential development as
well as single-family residential subdivisions and multi-family developments that do not
involve the subdivision of land.
Critical Area. The area adjacent to a water supply intake or reservoir where risk associated
with pollution is greater than from the remaining portions of the watershed. The critical
area is defined as extending either one-half mile from the normal pool elevation of the
reservoir in which the intake is located or to the ridge line of the watershed (whichever
comes first); or one-half mile upstream from the intake located directly in the stream or river
(run-of-the-river), or the ridge line of the watershed (whichever comes first). Local
governments may extend the critical area as needed. Major landmarks such as highways
or property lines may be used to delineate the outer boundary of the critical area if these
landmarks are immediately adjacent to the appropriate outer boundary of one-half mile.
Development. Any land disturbing activity which adds to or changes the amount of
impervious or partially impervious cover on a land area or which otherwise decreases the
infiltration of precipitation into the soil.
Discharging Landfill. A facility with liners, monitoring equipment and other measures to
detect and/or prevent leachate from entering the environment and in which the leachate is
treated on site and discharged to a receiving stream.
Existing Development. Those projects that are built or those projects that at a minimum
have established a vested right under North Carolina zoning law as of the effective date of
this ordinance based on at least one of the following criteria:
(1) substantial expenditures of resource(time, labor,money)based on a good faith reliance
upon having received a valid local government approval to proceed with the project,
or
(2) possession of an outstanding valid building permit as authorized by the General
Statutes (G.S. 153A-344.1), or
(3) substantial expenditure of resources (time, labor, or money) and having an approved
site specific or phased development plan in compliance with 160D-102.
Hazardous Material. Any substance listed as such in: SARA section 302, Extremely
Hazardous Substances, CERCLA Hazardous Substances, or Section 311 of CWA (oil and
hazardous substances).
Industrial Development. Any non-residential development that requires an NPDES permit
for an industrial discharge and/or requires the use or storage of any hazardous material for the
purpose of manufacturing, assembling, finishing, cleaning or developing any product or
commodity.
Landfill. A facility for the disposal of solid waste on land in a sanitary manner in accordance
with Chapter 130A Article 9 of the N.C. General Statutes. For the purpose of this ordinance
this term does not include composting facilities.
Major Watershed Variance. A variance that would completely eliminate a management
requirement, or reduce a management requirement with a numerical standard by more than ten
percent (10%).
Minor Watershed Variance. Any variance of the watershed regulations not considered a
major one as defined above.
Non-residential Development. All development other than residential development,
agriculture and silviculture.
Plat. A map or plan of a parcel of land which is to be, or has been subdivided.
Protected Area. The area adjoining and upstream of the critical area in a WSIV water supply.
The boundaries are defined as ten (10) miles upstream and draining to the intake located
directly in the stream or river.
Residential Development. Buildings for residence such as attached and detached single-family
dwellings, apartment complexes, condominiums, townhouses, cottages, etc. and their
associated outbuildings such as garages, storage buildings, gazebos, etc. and customary home
occupations.
Structure. Anything constructed or erected, including but not limited to buildings, which
requires location on the land or attachment to something having permanent location on the
land.
Toxic Substance. Any substance or combination of substances (including disease causing
agents), which after discharge and upon exposure, ingestion, inhalation, or assimilation into
any organism, either directly from the environment or indirectly by ingestion through food
chains, has the potential to cause death, disease, behavioral abnormalities, cancer, genetic
mutations, physiological malfunctions (including malfunctions or suppression in reproduction
or growth) or physical deformities in such organisms or their off spring or other adverse
health effects.
Water Dependent Structure. Any structure for which the use requires access to or proximity
to or citing within surface waters to fulfill its basic purposes, such as boat ramps, boat houses,
docks and bulkheads. Ancillary facilities such as restaurants, outlets for boat supplies,parking
lots and commercial boats storage areas are not water dependent structures.
Watershed. The entire land area contributing surface drainage to a specific point (e.g. the
water supply intake.)
Section 7-3 Development Regulations
7-3.1. Yadkin River - Critical Area (WS-IV-CA).
Density and Built-upon Limits:
1. Single-family residential development shall not exceed two (2) dwelling
unit per acre on a project-by-project basis. No residential lot shall be
less than one-half (1/2) acre, except within an approved cluster
development.
2. All other residential and non-residential development shall not exceed
twenty-four percent (24%) built-upon area on a project-by-project basis.
For the purpose of calculating the built-upon area, total project area shall
include total acreage in the tract on which the project is to be developed.
7-3.2 Yadkin River - Protected Area (WS-IV-PA).
Density and Built-upon Limits
1. Single-family residential development shall not exceed two (2) dwelling
units per acre, as defined on a project-by-project basis. No residential
lot shall be less than one-half (1/2) acre, or one-third (1/3) acre for
projects without a curb and gutter system, except within an approved
cluster development.
2. All other residential and non-residential development shall not exceed
twenty-four percent (24%) built-upon area on a project-by-project basis.
For projects without a curb and gutter street system, development shall
not exceed thirty-six percent (36%) built-upon area on a project-by-
project basis. For the purpose of calculating built-upon area, total project
area shall include acreage in the tract on which the project is to be
developed.
7-3.3 Cluster Development
Clustering of development is allowed in all drinking supply watershed areas
under the following conditions:
(a) Minimum lot sizes are not applicable to single-family cluster
development projects; however, the total number of lots shall not exceed
the number of lots allowed for single-family detached developments in
subsection 7-4.4(d) above. Built-upon area or stormwater control
requirements of the project shall not exceed that allowed for the critical
area or balance watershed, whichever applies.
(b) All built-upon area shall be designed and located to minimize stormwater
runoff impact to the receiving waters and minimize concentrated
stormwater flow.
(c) The remainder of the tract shall remain in a vegetated or natural state.
Where the development has an incorporated property owners association,
title of the open space areas shall be conveyed to the association for
management. Where a property association is not incorporated, a
maintenance agreement shall be filed with the property deeds.
7-3.4 Watershed Buffer Areas Required
(a) Stream Buffers: A minimum thirty (30) foot vegetative buffer for
development activities is required along all perennial waters indicated
on the most recent versions of U.S.G.S. 1:24,000 (7.5 minute) scale
topographic maps or as determined by local government studies.
Desirable artificial stream bank or shoreline stabilization is permitted.
(b) Development in Buffers: No new development is allowed in the buffer
except public projects such as road crossings and greenways where no
practical alternative exists. These activities should minimize built-upon
surface area, direct runoff away from the surface waters and maximize
the utilization of stormwater best management practices.
Section 7-4 Administration
7-4.1 Additional Duties
