This article is enacted to assure compliance
with this chapter and all applicable ordinances and regulations, to
protect and enhance the values of the natural environment in Northumberland
County, to protect the economic value of the natural environment from
unwise and disorderly development, to ensure the efficient use of
land and to create standards in the layout, design, landscaping and
construction of development.
A.
The site plan development process as described in
this article must be followed for all development or redevelopment
in CBPAs requiring a zoning permit, special exceptions permit, conditional
use permit, or rezoning request; or for a subdivision, planned unit
development or cluster development.
B.
Any development or redevelopment exceeding 2,500 square
feet of land disturbance shall follow the site plan development process
prior to any clearing or grading of the site or the issuance of any
building permit, to assure compliance with all applicable requirements
of this chapter.

A.
Purpose. The purpose of the water quality impact assessment
is to:
(1)
Identify the impacts of proposed land disturbance,
development, or redevelopment on water quality and lands within RPAs
and other environmentally sensitive lands;
(2)
Ensure that, where land disturbance, development,
or redevelopment does take place within RPAs and other sensitive lands,
it will be located on those portions of a site and in a manner that
will be least disruptive to the natural functions of RPAs and other
sensitive lands;
(3)
Protect individuals from investing funds for improvements
proposed for location on lands unsuited for such development because
of high groundwater, erosion or vulnerability to flood and storm damage;
(4)
Provide for administrative relief from terms of this
article when warranted and in accordance with the requirements contained
herein; and
(5)
Specify mitigation which will address water quality
protection.
B.
Water quality impact assessment required.
(1)
A water quality impact assessment is required for:
(2)
There shall be two levels of water quality impact
assessments: a minor assessment and a major assessment.
C.
Minor water quality impact assessment. A minor water quality impact assessment pertains only to proposed land disturbance, development, or redevelopment within CBPAs which creates impervious surfaces that total less than 16% of the parcel size and/or which proposes to modify or encroach into the landward 50 feet of the one-hundred-foot-wide buffer area as permitted under § 54-16C(2). A minor assessment must demonstrate through acceptable calculations that the undisturbed buffer area, enhanced vegetative plantings, and any necessary best management practices will result in removal of no less than 75% of sediments and 40% of nutrients from postdevelopment stormwater runoff and that will retard runoff, prevent erosion, and filter nonpoint source pollution the equivalent of the full undisturbed one-hundred-foot-wide buffer area. A minor assessment shall include a site drawing to scale which shows the following:
(1)
Location of the components of the RPA, including the
one-hundred-foot-wide buffer area and the location of any water body
with perennial flow.
(2)
Location and nature of the proposed encroachment into
the buffer area, including type of paving material; areas of clearing
or grading; location of any structures, drives or other impervious
cover; and sewage disposal systems or reserve drainfield sites.
(3)
Type and location of proposed best management practices
to mitigate the proposed encroachment.
(4)
Location of existing vegetation on site, including
the number and type of trees and other vegetation to be removed in
the buffer to accommodate the encroachment or modification.
(5)
Revegetation plan that supplements the existing buffer
vegetation in a manner that provides for pollutant removal, erosion,
and runoff control.
D.
Major water quality impact assessment.
(1)
A major water quality impact assessment shall be required
for any development which:
(a)
Exceeds 5,000 square feet of land disturbance
within CBPAs and proposes to modify or encroach into the landward
50 feet of the one-hundred-foot-wide buffer area;
(b)
Proposes to disturb any portion of the seaward
50 feet of the one-hundred-foot-wide buffer area; provided, however,
that for lots recorded prior to September 20, 1990, only a minor water
quality impact assessment shall be required.
(c)
Is located in an RMA and is deemed necessary
by the Administrator.

be considered that some of the elements are unnecessary due to the
scope and nature of the proposed use and development of the land.

(4)
As part of any major water quality impact assessment
submittal, the Administrator may request review by the Chesapeake
Bay Local Assistance Department (CBLAD). Upon receipt of a major water
quality impact assessment, the Administrator will determine if such
review is warranted and may request CBLAD to review the assessment
and respond with written comments. Any comments by CBLAD will be incorporated
into the final review by the Administrator, provided that such comments
are provided by CBLAD within 90 days of the request.
(5)

The cumulative impact of the proposed development,
when considered in relation to other development in the vicinity,

of the butter area.
(e)
Impervious surface is minimized.
(f)

revegetation plan and site design, result in minimal disturbance to
all components of the RPA, including the one-hundred-foot-wide buffer

Editor's Note: Former § 54-32, Period
of validity of approved final plan, was repealed 10-14-2004.
A.
After a final plan has been approved by the Administrator,
minor adjustments of the final plan, which comply with the spirit
of this article and other provisions of this chapter and with the
general purpose of the comprehensive plan for development of the area,
may be approved by the Administrator. Deviation from an approved final
plan without the written approval of the Administrator shall void
the plan, and the Administrator shall require the applicant to resubmit
a new plan for consideration.
B.
Any major revision of an approved final plan may be
made in the same manner as originally approved, and any requirements
of this article may be waived by the Administrator in specific cases
where such requirement is found to be unreasonable and where such
waiver will not be adverse to the purpose of this chapter.
In the event that the final plan or any component of the final plan is disapproved and recommended conditions or modifications are unacceptable to the applicant, the applicant may appeal such administrative decision to the governing body. The appeal must be made in writing and filed within 30 days after notification of the decision as provided in § 54-30C(4) of this chapter. In granting an appeal, the governing body must find such plan to be in accordance with all applicable ordinances and include necessary elements to mitigate any detrimental impact on water quality and upon adjacent property and the surrounding area, or such plan meets the purpose and intent of the performance standards in this chapter. If the governing body finds that the applicant's plan does not meet the above-stated criteria, it shall deny approval of the plan.
