§ 92-18. Engineered site grading plans, contents.

(a)

One hard copy and one electronic copy of engineered site grading plans for a development shall be submitted by the proprietor to the city; provided, however, if and to the extent the same information has been previously submitted as required under a separate ordinance requirement, then, the applicant shall provide copies of the previous submission, together with new information required hereunder which has not been previously submitted.

(b)

The engineered site grading plan shall include the following information subject to the exception specified in subsection (a) above:

(1)

A plan showing the layout of the area intended to be developed will be submitted by the applicant or their representative. This plan will be prepared under the direction of, and sealed by, a registered professional engineer or a registered land surveyor, and shall fit on a sheet of paper that does not exceed 24" x 36", drawn to a standard engineering scale not less than 1" = 50'.

(2)

The legal property description and a north indicator.

(3)

Existing grades on a 50-foot grid to a minimum of 50 feet beyond the site property line and sufficient intermediate grades to determine such things as ditches, swales, adjacent pavement, buildings, and other pertinent features.

(4)

Location of any watercourses, wetlands, woodlands, environmental feature setback areas (as specified in the zoning ordinance), lakes, and ponds on the site.

(5)

Existing easements.

(6)

Existing utilities, manholes, and culverts.

(7)

Road rights-of-way, existing and proposed.

(8)

Proposed topography of the site.

(9)

Location and description of any existing and proposed stormwater management and soil erosion control measures.

(10)

Flow direction(s) of stormwater runoff onto and from the site before and after development, including the direction of overland flow.

(11)

Proposed elevations shall be underlined or boxed in to differentiate from existing elevations. It is expected that all elevations shall be in hundredths of a foot.

(12)

A location map.

(13)

The general stormwater management scheme for the proposed development indicating how stormwater management will be provided and where drainage will outlet.

(14)

A description of the off-site outlet and evidence of its adequacy. If no adequate watercourse exists to effectively handle a concentrated flow of water from the proposed development, discharge will be reduced to sheet flow prior to exiting the site, and cannot exceed the allowable outlet rate defined in the engineering design standards. Additional volume controls may be required in such cases and/or acquisition of rights-of-way from downstream property owners receiving the stormwater flow.

(15)

Any on-site and/or off-site stormwater management facilities and appropriate easements, dedicated to the entity that will be responsible for future maintenance.

(16)

Any drainage originating outside of the development limits that flows onto or across the development. (In general, drainage from off-site shall not be passed through on-site stormwater BMPs).

(17)

Any natural watercourses and county drains that traverse or abut the property.
