(a) Any person or persons proposing to develop or redevelop land within the City for any of the uses listed in Section 1049.03(a) shall design, develop, and submit a site development plan (SDP) as described below. Said plan will be evaluated to determine the potential for erosion, runoff, and sedimentation impacts that may result from such development activities and the need for submission of a storm water management plan (SMP).
(b) No earth disturbing activity subject to regulation under this chapter shall be undertaken for any land proposed for development or redevelopment for uses specified under Section 1049.03(a) without an approved SDP and, if appropriate, an approved SMP.
(c) This final plan must be signed by an Ohio licensed professional engineer (PE), who will verify that the design of all storm water management practices meet the submittal requirements outlined in the Rainwater and Land Development Manual.
(d) Final approval of a proposed development or redevelopment shall not be given unless:
(1) A determination is made by the authorized agent based on submission of a SDP that the proposed earth disturbing activity will not cause accelerated runoff, erosion, and/or sediment impacts harmful to the quality of off-site lands and waters; or
(2) A SMP has been approved by the authorized agent of the City based on the recommendation of its authorized agent that determines that the proposed earth
disturbing activity will not cause accelerated runoff, erosion, and/or sediment impacts harmful to the quality of off-site lands and waters.
(3) Any person seeking approval of land development proposals for use types listed in Section 1049.03(a) shall develop and submit a SDP. The applicant is encouraged to have a pre-submission meeting with the City authorized agent.
(e) Storm Water Design Manual. The Rainwater and Land Development Manual includes a list of acceptable storm water treatment practices, including the specific design criteria and operation and maintenance requirements for each storm water practice. The manual may be updated and expanded from time to time, at the discretion of the local review authority, based on improvements in engineering, science, monitoring and local maintenance experience. Storm water treatment practices that are designed and constructed in accordance with these design and sizing criteria will be presumed to meet the minimum water quality performance standards.
(f) Site Development Plan Requirements.
(1) Each applicant shall provide information that details the location of the area proposed for development, the site in relation to its general surroundings, predevelopment site conditions, existing characteristics of the site, and the extent of proposed earth disturbing activities. At a minimum the plan shall include the following elements:
A. Contact information. The name, address, and telephone number of all persons having a legal interest in the property and the tax reference number and parcel number of the property or properties affected.
B. General location map that shows the area proposed for development and pertinent adjacent areas and features.
C. A description of the nature and type of the earth disturbing/construction activity (e.g. residential, commercial, highway, etc.) *
D. A photocopy of the appropriate soil survey sheet found in the USDA Soil Survey of Montgomery County with location of site identified.
E. A site plan map that shows the location of existing features and proposed improvements on the site including:*
1. Total area of the site and the area of the site that is expected to be disturbed (i.e. grubbing, cleaning, excavation, filling or grading, including off-site borrow areas).*
2. Surface water locations, including springs, wetlands, streams, lakes, water wells, etc., on or within 200 feet of the site, including the boundaries of wetlands or stream channels and first subsequent named receiving water(s) the permittee intends to fill or relocate for which the permittee is seeking approval from the Army Corps of Engineers and/or Ohio EPA.*
3. The general directions of surface water flow and 100-year floodplain when applicable.
4. All improvements, including buildings, retaining walls, sidewalks, streets, parking lots, driveways, utilities and storm water basins, drainage impoundments, channels and outlets, etc.*
5. An estimate of the impervious area and percent imperviousness created by the earth disturbing activity.*
F. Landscaping and stabilization requirements. In addition to the above requirements, a landscaping plan must be submitted with the final design describing the vegetative stabilization and management techniques to be used at a site after construction is completed. This plan will explain not only how the site will be stabilized after construction, but who will be responsible for the maintenance of vegetation at the site and what practices will be employed to ensure that adequate vegetative cover is preserved. This plan must be prepared by a registered landscape architect or by the Montgomery County Soil and Water Conservation District, and must be approved by the authorized agent prior to receiving a permit.
(2) The items in this section marked with an asterisk (*) are also requirements of the storm water pollution prevention plans (SWP3s) required in the Ohio EPA's NPDES Construction Activity Permit #OHC000002, effective April 21, 2003.
(g) Site Development Plan Submission, Review and Action.
(1) Submission of a site development plan by an applicant seeking approval initiates the review process. The City's authorized agent shall review the site development plan and conduct a site inspection of the proposed site. Review of the site development plan shall be completed within ten business days of submittal.
(2) Following the review, the authorized agent shall:
A. Approve the site development plan;
B. Conditionally approve the site development plan pending additional information and/or the incorporation of required changes; or
C. Require the submission of a SMP based on written findings of the authorized agent.
