(A) For land-disturbing activity associated with development of a single-family dwelling or a two-family dwelling, a plot plan of the lot or site on which the building is to be located shall be submitted to the building inspector for review and approval by the Director.
(B) The plot plan shall be prepared by a registered surveyor, professional civil engineer, or other qualified professional approved by the Director and shall show the finished floor elevation of the building in relation to the natural ground surface and in relation to the uppermost point of the crest, summit or ridge top of the mountain or hill on which the building is constructed.
(C) The plot plan shall also indicate the limits of the area to be disturbed and the slope of the buildable area. Areas proposed or required to remain undisturbed shall be marked on the plot plan and in the field with tape, orange plastic fencing, or other approved marker until a certificate of occupancy is issued or as otherwise approved by the Director.
(D) The following additional information shall be submitted along with the plot plan.
(1) Level I requirements. Every application for authorization to undertake land disturbing activities associated with development of a single-family dwelling or two-family dwelling within a subdivision that was previously approved under the provisions of this chapter shall contain a topographic survey and/or analysis as outlined in § 156.11(C)(1) above.
(2) Level II requirements. Every application for authorization to undertake land disturbing activities associated with development of a single-family dwelling or two-family dwelling not within a subdivision that was previously approved under the conditions of this chapter shall contain a topographic survey of the lot with contour intervals of no more than two feet and a certification of maximum structure height as per § 156.11(C)(1) and (2) above. An analysis of the county soils map shall accompany the application. If the soils map indicates the presence of problematic soils or the topographic survey indicates that the average slope of the proposed building and grading envelope is greater than 30%, then the application requirements found in division (D)(3) below shall apply.
(3) Level III requirements.
(a) Level III requirements apply to any application to develop a single-family dwelling or two-family dwelling where:
1. The soils report confirms the presence of problematic soil types; and/or
2. The natural slope of the proposed building and grading envelope equals or exceeds 30%.
(b) In addition to the topographic survey and certification of maximum building height required in division (D)(2) above, level III applications shall also contain the following information:
1. A soils report meeting the requirements of § 156.11(C)(3) above, if one has not already been provided;
2. A hydrological report and plan meeting the requirements of § 156.11(C)(4) above; and
3. A geotechnical analysis and report meeting the requirements of § 156.11(C)(5) above.
