Dublin Municipal Code Art. IV Site Plans and Documentation

In addition to the site plan requirements of the building code and Appendix G, additional site plan information shall include, as applicable to the proposed development:

A. Location of the proposed activity and proposed structures; locations of water supply, sanitary sewer, and other utilities; and locations of existing buildings and structures.

B. Location, extent, amount, and proposed final grades of any filling, grading, or excavation.

C. Where the placement of fill is proposed, the amount, type, and source of fill material; compaction specifications; a description of the intended purpose of the fill areas; and evidence that the proposed fill areas are the minimum necessary to achieve the intended purpose.

D. Existing and proposed alignment of any proposed alteration of a watercourse.

E. A nonconversion agreement signed by the applicant if the building in a flood hazard area has enclosed areas below the lowest floor.

(Ord. 13-22 § 3 (Exh. B))

When additional hydrologic, hydraulic or other engineering data, studies, and additional data and analyses are submitted to support an application, the applicant has the right to seek a Letter of Map Change from FEMA to change the base flood elevations, change floodway boundaries, or change boundaries of flood hazard areas shown on FIRMs, and to submit such data to FEMA for such purposes. The analyses shall be prepared by a qualified registered professional engineer in a format required by FEMA. Submittal requirements and processing fees shall be the responsibility of the applicant. Provided FEMA issues a Conditional Letter of Map Revision, construction of proposed flood control projects and land preparation for development are permitted, including clearing, excavation, grading, and filling. Permits for construction of buildings shall not be issued until the applicant satisfies the FEMA requirements for issuance of a Letter of Map Revision.

(Ord. 13-22 § 3 (Exh. B))

For projects proposing to enclose areas under elevated buildings, include a signed Nonconversion Agreement (Declaration of Land Restriction) which shall be recorded on the property prior to issuance of the certificate of occupancy.

(Ord. 13-22 § 3 (Exh. B))

Where flood hazard areas are delineated on the FIRM and base flood elevations data have not been provided, the Floodplain Administrator is authorized to:

A. Require the applicant to include base flood elevation data prepared by a qualified professional engineer in accordance with currently accepted engineering practices. Such analyses shall be performed and sealed by a qualified professional engineer. Studies, analyses and computations shall be submitted in sufficient detail to allow review and approval by the Floodplain Administrator. The accuracy of data submitted for such determination shall be the responsibility of the applicant.

B. Obtain, review, and provide to applicants base flood elevation and floodway data available from a federal or state agency or other source or require the applicant to obtain and use base flood elevation and floodway data available from a federal or state agency or other source.

C. Where base flood elevation and floodway data are not available from another source, where the available data are deemed by the Floodplain Administrator to not reasonably reflect flooding conditions, or where the available data are known to be scientifically or technically incorrect or otherwise inadequate, require the applicant to include base flood elevation data in accordance with subsection A of this section.

D. Where the base flood elevation data are to be used to support a request for a Letter of Map Change from FEMA, advise the applicant that the analyses shall be prepared by a qualified professional engineer in a format required by FEMA, and that it shall be the responsibility of the applicant to satisfy the submittal requirements and pay the processing fees.
