A. Site grading is the excavation or filling of any lot or parcel that changes the existing contours of the parcel. A permit shall be required for:
1. The site grading of any lot or parcel of land within the city which is one-fourth (1/4) of an acre or larger and which has not previously been granted a building permit or approved development plan relating to the proposed site grading for the site.
2. Sites where a building permit is under review and developer/owner would like grading to commence as long as all site grading issues have been addressed and resolved.
3. Any site that contains a stormwater management area, i.e., detention/retention basin, bioswales, etc., and will be doing any type of grading work, including maintenance activities.
4. Sites that are located in an SFHA (special flood hazard area), i.e., floodplain/floodway.
B. A site grading permit application, together with the following documents, shall be submitted for approval by the city engineer:
1. A topographic survey of the parcel showing the existing and proposed contours, existing utilities, foundation elevation of adjacent buildings within one hundred feet (100'), nearest storm sewer structure or culvert, and, where applicable, the 100-year flood elevation and wetlands delineation (the limits of both which shall be staked at 50 foot intervals). The survey shall be signed and sealed by an Illinois registered professional engineer.
2. A detention facility design appropriate for the zoning classification showing point release of stormwater channeled or piped to the nearest storm sewer system.
3. An erosion control plan, and for parcels one acre or larger, an NPDES permit from IEPA shall also be required.
C. Following the grading, the completed site shall be topsoiled and stabilized by either seed and mulch or sod within the requirements of the Illinois ILR10 permit.
D. A fee of one hundred fifty dollars ($150.00) shall be paid to the city of Batavia for processing the permit application. In addition, a letter of credit will be due at the time of issuance of the grading permit to cover the cost of grading and stabilization measures based on an engineer's estimate approved by the city engineer. The terms of the permit are as follows:
1. A grading permit shall be valid for one year from the date of issuance.
2. A grading permit may be extended for one additional year with submission of a renewed permit application, payment of a one hundred dollar ($100.00) renewal fee prior to the expiration of the original grading permit and justification for extension of permit.
a. Site grading work under a renewed grading permit must be completed by the end of the one year renewal period.
b. Site grading work not completed at the expiration of an approved renewed site grading permit shall be in violation of this code. At that time, the city shall draw on the letter of credit to complete the grading and stabilize the site.
c. Any grading permits previously granted prior to approval of this amendment shall only be allowed one additional year to comply with this updated provision from date of expiration, i.e., no more than two (2) years to complete grading without being in violation of this code.
E. Upon completion of the site grading a topographic survey showing that the completed work is in compliance with the approved grading plan must be submitted. The survey shall be signed and sealed by a professional engineer or land surveyor registered in the state of Illinois. (Ord. 16-04, 2-15-2016)
