§ 16-30. Site plans.

(a)

All site plans submitted in accordance with applicable provisions of this chapter must meet the requirements for their preparation and must also provide information to enable a determination to be made by the community development director as to plan conformance with the public policy statements of this chapter.

(b)

All persons proposing developments, redevelopments or construction must submit site plans to the community development director illustrating the means by which conformance with policy provisions may be achieved and illustrating compliance with applicable development standards before issuance of a development or building permit.

(c)

Electric, telephone and gas utilities must submit plans and obtain a development permit only for major transmission installations located within rights-of-way or easements devoted exclusively to installations of utility facilities. Individual single-family lots within approved subdivisions are exempt from these requirements for new residential construction with the exception that individual single-family lots where site plans for each are required by special designation on the recorded plat or where such lots are located within special flood hazard areas must be submitted for review and approval in accordance with this division and other applicable provisions of this chapter. Owners and developers of individual single-family lots are required to use best management practices to prevent sedimentation from leaving the site.

(d)

Grading, erosion control, sedimentation control, water quality control and stormwater management plans must be prepared by or under the supervision of a state-registered and authorized professional, as may be appropriate for project planning and design. Tree protection plans may be prepared by and implemented under the supervision of a currently state-registered professional architect, forester, landscape architect or engineer as may be appropriate for project planning and design. When the hydrologic engineering analysis includes applications of the principles for flood routing, super critical flow, high energy dissipation or conversion, backwater curves, floodplain studies or other advanced hydrologic engineering techniques, the analysis must be made by a currently state-registered professional with demonstrated proficiency in hydrology.

(e)

Site plans and supporting documentation to show conformance with this chapter must be submitted in accordance with the applicableprovisions of the city zoning ordinance and all conditions of zoning and must include the following:

(1)

Evidence of conformance with the requirements of this chapter for grading, vegetation alteration, erosion control, sedimentation control, water quality control and drainage system alteration or development. Grading plans must illustrate existing and proposed contours to the two-foot interval at a minimum. Water quality plans must include the identification of existing wetland areas within the development site and must demonstrate use of the stormwater quality site development review tool. Related plans must show locations of structures, roads, surface drainage, existing and proposed drainage conduits, buffer areas, stream buffers, state buffer zones, and proposed alterations to the existing site.

(2)

A hydrologic engineering analysis of stormwater runoff under pre-developed and post-developed site conditions and a detailed evaluation of the projected effects on upstream and downstream properties within the affected drainage basin. In determining downstream effects from stormwater management structures, BMPs, and the development, hydrologic-hydraulic engineering studies must extend downstream to a point where the proposed development represents less than ten percent of the total watershed. This analysis must include a determination of the culvert, floodplain and channel cross-section area required to carry the affected runoff.

(3)

Delineation of the boundaries of the special flood hazard areas for streams draining in excess of 100 acres. The actual building site in relation to the special flood hazard areas boundaries must be shown; the same information must be indicated by the seller to the purchaser of each property so affected.

(4)

The projected sequence of work represented by the grading, vegetation, erosion control, sedimentation control, water quality control and stormwater management plans as related to other major items of construction.

(5)

Upon development project completion, location, size and invert elevations of piped segments of the stormwater management system, of control weirs, BMPs and water surface elevations and volumes in detention ponds must be shown on the final plat for a subdivision, and on as-built drawings for other developments, which must be submitted to the community development director prior to approval. The authorized, state-registered professional reviewing the construction must provide a certificate that the development is in substantial compliance with approved plans. As-built elevation certifications prepared by currently state-registered land surveyors or currently state-registered professional engineers for all developments, including fill, allowed within a floodprone area, must be submitted to the community development director.

(6)

A separate tree protection plan in conformance with the requirements of this chapter.
