(A) The stormwater management plan, required in § 153.04, shall apply the stormwater management technical criteria set forth in § 153.09 to the entire land disturbing activity, consider all sources of surface runoff and all sources of subsurface and groundwater flows converted to surface runoff, and include the following information:
(1) Information on the type and location of stormwater discharges; information on the features to which stormwater is being discharged including surface waters or karst features, if present, and the predevelopment and post-development drainage areas;
(2) Contact information including the name, address, and telephone number of the owner and the tax reference number and parcel number of the property or properties affected;
(3) A narrative that includes a description of current site conditions and final site conditions;
(4) A general description of the proposed stormwater management facilities and the mechanism through which the facilities will be operated and maintained after construction is complete;
(5) Information on the proposed stormwater management facilities, including:
(a) The type of facilities;
(b) Location, including geographic coordinates;
(c) Acres treated; and
(d) The surface waters or karst features, if present, into which the facility will discharge.
(6) Hydrologic and hydraulic computations, including runoff characteristics;
(7) Documentation and calculations verifying compliance with the water quality and quantity requirements of 9 VAC §§ 25-870-62 through 25-870-92 of the regulations; and
(8) A map or maps of the site that depicts the topography of the site and includes:
(a) All contributing drainage areas;
(b) Existing streams, ponds, culverts, ditches, wetlands, other water bodies, and floodplains;
(c) Soil types, geologic formations if karst features are present in the area, forest cover, and other vegetative areas;
(d) Current land use including existing structures, roads, and locations of known utilities and easements;
(e) Sufficient information on adjoining parcels to assess the impacts of stormwater from the site on these parcels;
(f) The limits of clearing and grading, and the proposed drainage patterns on the site;
(g) Proposed buildings, roads, parking areas, utilities, and stormwater management facilities; and
(h) Proposed land use with tabulation of the percentage of surface area to be adapted to various uses including, but not limited to, planned locations of utilities, roads, and easements.
(B) A stormwater management plan for a land disturbing activity shall apply the stormwater management technical criteria set forth in this part to the entire land disturbing activity. Individual lots in new residential, commercial, or industrial developments shall not be considered separate land disturbing activities.
(C) If an operator intends to meet the water quality and/or quantity requirements set forth in § 153.09 through the use of off-site compliance options, where applicable, then a letter of availability from the off-site provider must be included. Approved off-site options must achieve the necessary nutrient reductions prior to the commencement of the applicant’s land disturbing activity except as otherwise allowed by the VA Code.
(D) Elements of the stormwater management plans that include activities regulated under VA Code §§ 54.1-400 et seq. shall be appropriately sealed and signed by a professional registered in the state pursuant to VA Code §§ 54.1-400 et seq.
(E) A construction record drawing for permanent stormwater management facilities shall be submitted to the Administrator. The construction record drawing shall be appropriately sealed and signed by a professional registered in the state, certifying that the stormwater management facilities have been constructed in accordance with the approved plan. An Administrator may elect not to require construction record drawings for stormwater management facilities for which maintenance agreements are not required pursuant to § 153.10(B).
