Sec. 23.2-8.  Water Quality Impact Assessments (WQIA).

(a) A water quality impact assessment (WQIA) shall be required for:

    (1) Any proposed land disturbance, development or redevelopment activity within a RPA as permitted by this chapter;

     (2) Any buffer modification, noncomplying use and development waiver, exception, exemption, allowable land development or encroachment as provided for in this chapter;

     (3) Any development activity in the RMA as deemed necessary by the CBPA Manager due to the unique site characteristics or intensity of the proposed use or development.

(b) The purpose of the WQIA is to:

     (1) Identify the impacts of proposed land disturbance, development or redevelopment on water quality and lands in the RPA and other environmentally sensitive lands;

     (2) Ensure that where land disturbance, development or redevelopment does take place within the RPA and other sensitive lands, it will occur on those portions of the site and in a manner that will be least disruptive to the natural functions of the RPA and other sensitive lands;

     (3) Provide documentation for requests for development approval or administrative relief from terms of this chapter when warranted and in accordance with the requirements contained herein; and

      (4) Specify mitigation that will address water quality protection.

(c) A WQIA shall include a narrative and site drawings that address the evaluation criteria and that depict, address and includes the following:

      (1) Location of the components of the RPA;

    (2) Location and nature of the proposed encroachment, noncomplying use or development waiver, exception, exemption, allowable land development or modification of the buffer area, including: type of paving material; areas of clearing; filling 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 and supporting calculations to mitigate any proposed encroachment and/or modification;

     (4) Location of existing vegetation, including the number and type of trees and other vegetation in the buffer proposed to be removed to accommodate the encroachment, noncomplying use and development waiver, exception, exemption, allowable land development or modification, and number and type of trees to remain;

     (5) Revegetation plan that supplements the existing buffer vegetation and specifies the proposed replacement vegetation in accordance with the Buffer Guidelines;

     (6) Erosion and sediment control and construction sequencing; and

     (7) A copy of all required permits from all applicable agencies necessary to develop the project or a status of the acquisition of each.

(d) The WQIA shall be submitted to the CBPA Manager for review and approval concurrent with the submission of applications for review and approval of site plans, subdivision plans, applications for land disturbing activity permits, building permits, buffer modification, buffer encroachment, noncomplying use and development waiver, allowable land development, exemptions or exceptions.

(e) Upon completing review of a WQIA the CBPA Manager will determine whether the proposed buffer modification, buffer encroachment, noncomplying use and development waiver, allowable land development, exemption, or application for a exception is consistent with the provisions of this chapter and make a finding based upon the following evaluation criteria:

(f) The CPBA Manager may require additional mitigation where potential impacts have not been adequately addressed.
