§ 8-211. Stormwater Management Plan.

(a)

The applicant shall also submit a separate plan labeled Stormwater Management Plan which identifies the methods to be used to control run-off, erosion, sedimentation and drainage expected to occur while the project is ongoing, and before final grading, that may adversely impact adjacent properties or public rights-of-way. The Stormwater Management Plan shall also include:

(1)

Detail regarding the intended interim on-site storage, placement, fill and disposal of earth materials; and

(2)

A specific plan to eliminate the adverse impacts from stormwater runoff, including, but not limited to, interim soil stabilization devices and proposed measures for erosion and sedimentation control for all times during construction work and specifically during demolition; between completion of demolition and the commencement of construction work; and continuing through the construction work, until final grading. All such proposed measures shall be based upon the standards and requirements contained in the latest edition of the Illinois Urban Manual, compiled by the IEPA and Department of Agriculture.

(b)

Final grading. To the extent the Village Engineer determines that the proposed final grade, land contour or drainage pattern may, upon project completion, adversely impact adjacent properties or public rights-of-way, the Site Grading Plan shall also include:

(1)

Data regarding the classification, distribution, strength and erodability of existing soils;

(2)

Data regarding the nature, distribution, strength and erodability of earth materials, if any are to be placed on the site;

(3)

Level of water table;

(4)

Plans for permanent soil stabilization upon project completion;

(5)

Design criteria for corrective measures, when necessary; and

(6)

An alternate proposal for final grading that will eliminate the identified adverse impacts.

(c)

As-graded. Upon final completion of the work, the Village Engineer may require an as-graded plan which would include the following:

(1)

Approved Site Grading Plan;

(2)

Ground surface elevations;

(3)

As-graded ground surface elevations;

(4)

Lot drainage patterns;

(5)

Locations and elevations of all surface and subsurface drainage facilities;

(6)

Location, species and size in DBH of each existing tree retained on the subject property and each new tree proposed to be added to the subject property.
