§ 9. Southern Rivers Watershed Management Plan.

(a)

The developer of any land within the Southern Rivers Watershed shall, prior to undertaking any land-disturbing activity, submit a Southern Rivers Watershed Management Plan if such development is subject to the requirements of section 7(e) hereof. No such land-disturbing activity shall take place until the plan is approved and all required permits and approvals have been granted. There shall be included in the plan sufficient information for the development services center and the departments of planning, agriculture and public works to evaluate the environmental characteristics of the affected areas, the potential and predicted impacts of the proposed activity on waters and wetlands within the Southern Rivers Watershed and the effectiveness and acceptability of those measures proposed by the applicant for preventing or minimizing adverse impacts. The plan shall contain maps, charts, graphs, tables, photographs, narrative descriptions and explanations and citations to supporting references, as appropriate, to communicate the information required by this section.

(b)

The plan shall contain the name, address and telephone number of the owner of the property sought to be developed and the developer of such property and a statement signed by the owner indicating his or her consent to the proposed development. In addition, the legal description of the property shall be provided and its location with reference to such landmarks as major water bodies, adjoining roads, railroads or subdivisions shall be clearly identified by a map.

(c)

The plan shall include a detailed description of the existing environmental and hydrologic conditions of the site and receiving waters, including the following information as appropriate to the circumstances:

(1)

The direction, flow rate and volume of stormwater runoff under existing conditions;

(2)

The location of areas on the site where stormwater collects or percolates into the ground;

(3)

A description of all watercourses, water bodies and wetlands on or adjacent to the site or into which stormwater flows. Information regarding their water quality and the current water quality classification, if any, given them by the Virginia Water Control Board shall be included;

(4)

Groundwater levels, as indicated by the Virginia Beach Soil Survey;

(5)

Location of floodplains, including floodways and special flood hazard areas;

(6)

Identification of vegetation existing on the site;

(7)

The topography of the site; and

(8)

Soil types or taxonomic units existing on the site.

(d)

Proposed alterations of any site containing, or adjacent to, a wetland or shoreline shall be prescribed in detail. Such description shall address:

(1)

Changes in topography resulting from development;

(2)

Areas where vegetation will be cleared or killed;

(3)

Areas to be covered with impervious surfaces, including a description of the surfacing material; and

(4)

The size, location and proposed use of any buildings or other structures.

(e)

Predicted impacts of the proposed development on existing conditions shall be described in detail. Such description shall address:

(1)

Changes in water quality;

(2)

Changes in groundwater levels;

(3)

Changes in the incidence and duration of flooding on the site and upstream and downstream from it; and

(4)

Impacts on wetlands and natural heritage resources.

(f)

A plan for the control of stormwater runoff, identifying all components of the drainage system and any measures for the detention, retention or infiltration of water, shall be described in detail.

(g)

The location of on-site potable water wells and wastewater facilities shall be identified.

(h)

A plan for the maintenance of best management practice facilities.

(i)

Erosion and sedimentation facilities shall be maintained in accordance with the Virginia Erosion and Sediment Control Handbook.

(j)

Stormwater management facilities shall be inspected twice each year and following every storm which causes the capacity of the facility to be exceeded to ensure that the facility remains operational. Any failures shall be corrected immediately.

(k)

The plan shall include any other information which the developer or the departments of planning and public works believe is reasonably necessary for an evaluation of impacts of the development upon water quality.
