(A) A drainage plan that does not contain as much information as drainage plans prepared to fulfill the requirements of § 152.20 and that is not prepared or certified by a registered professional engineer, land surveyor or architect engaged in storm drainage design, may be submitted when:
(1) No part of the parcel or property for which the drainage permit is requested is in an impacted drainage area; and
(2) The primary basis on which a drainage permit is required is the construction, enlargement or location, on a permanent foundation, of a one-family dwelling, two-family dwelling or accessory structure appurtenant to either a one-or two-family dwelling.
(B) (1) The drainage plan must be submitted in triplicate and shall indicate the nature and location of all work to be accomplished pursuant to a drainage permit. The drainage plan must be neat, accurate and readable. One copy of the drainage plan will remain on file with the Board.
(2) The following information must be submitted for approval under this section:
(a) The legal description and the street address for the property;
(b) The dimensions and borders of the parcel;
(c) The name and address of the owner;
(d) An arrow indicating north;
(e) Location and measurements of all existing and proposed improvements, structures and paved areas on the site;
(f) Existing and proposed grading showing positive drainage by contouring or sufficient spot elevations; and
(g) Location of all existing or proposed swales, ditches, culverts, drainage channels, surface and subsurface drainage devised and the direction of the flow.
(C) The drainage plan shall include information necessary to demonstrate conformity with all drainage requirements of this subchapter. The plot map shall illustrate the surface drainage pattern of the site away from structures and the final distribution of surface water off site, either preventing or planning for surface ponding.
(D) Notwithstanding provisions of §§ 152.20 and this section, submission of a drainage plan shall not be required as a precondition for obtaining a drainage permit in the instance of a one- or two-family dwelling constructed in a subdivision for which a plat has been approved in accordance with the subdivision control regulations, and for which a drainage plan meeting the requirements of this subchapter has been approved and a permit issued, so long as the permit applicant certifies that the land alteration shall be accomplished in compliance with the specifications and information found on the approved plat and on such drainage plan. Any deviations from the drainage provisions as approved in the plat and drainage plan for the subject plot must be submitted to the Board for approval and the Board may require the submission of plans or other information relative to the deviation which may be required as a precondition to approval.
