Technical Services

It is the intent of the District to maximize the water quality benefits during and after construction, while also minimizing the potential for soil loss and impacts on habitat, trees, wetlands and floodplains.  This requires that both temporary and permanent best management practices be thoroughly considered during the design, construction, and long term maintenance of the facility.  The use of current standards, identified in the Illinois Urban Manual, is encouraged. Often the facility is designed to only satisfy ordinance requirements pertaining to stormwater runoff. Opportunities to provide additional benefits exist but are seldom included in the stormwater management design.

In the development of the facility concept, consideration should be given to minimizing impacts on other competing objectives and that the concept be part of the overall site plan development from an aesthetics viewpoint.

Aerial  Maps
NCCSWCD can provide digital copies of historic aerial maps of sections of our District.

For the purpose of funding the reproduction and restoration of our historic aerial collections, the following is our policy for all reproductions made:

• Paper Reproduction In-House:  You may make paper copies for $1.00 a sheet.
• Digital Reproduction In-House: Use of a personal scanner to make record of a photo will be billed at $20 per photo. Digital photographs taken of aerial photos will be billed at $10 per picture taken.
• Request for Mailing: Aerial research, copy, and mailing will be billed at $10 for the first two sheets and $4 per sheet thereafter.

Natural Resources Information Reports (NRI) Policies
1) If an NRI application covers property which lies partially in two different counties, the county with the most acreage involved will issue the report.

2) If there is no natural resource information available on a site, i.e. soils, no floodplains, or wetlands, or no changes to the tributary diversions and there would be very minimal environmental impact, send a cover letter to all involved.  This includes the village officials and the petitioner.
This letter should state that the petitioner has complied with Section 22.02a.    Fee:  $50

3) If a site has been previously reviewed and the same petitioner applies again, we will check to make sure that proposed development is the same or similar and that there is no zoning change.  Dependent on development changes on adjacent property, there may or may not be significant impacts.  Send a new cover letter stating these possible impacts. However, we will need to review the site for wetlands, since this has become an important issue lately.  It may not have been considered in the original report.     Fee: $75

4) If a site has been previously reviewed and the same petitioner applies again, we will check to make sure the proposed development is the same or similar and that there is no zoning change.  However, after reviewing the site, we will need additional thought from the first report.  This will require a cover letter and a change of conclusions from the first report.  We will amend original report using some of the information in that report.   Fee: $150

5) If a different petitioner applies for an assessment on a site, which previously has been reviewed, check for zoning changes and how many years since the last report.  If it has been many years since the last report, and if there are significant changes in the proposed use and adjacent land use practices, we will issue a full report.  We will mention the old report in the new assessment.  In cases like this, be aware of the fact that a developer may not have developed this property for a reason.  If an area was planned as stormwater detention for a project, then many years later that detention area gets developed, they may have skirted the required detention issue.  In this case, the Metropolitan Water Reclamation District (MWRD) should receive a copy so they will be notified.  Fee:  normal NRI fees apply

6) Dependent upon the natural resources on the site, we will send copies of our report to other agencies:
a.  if there is modification or construction within the designated floodway, send a copy to IDOT/IDNR Office of Water Resources Permit Section.
b. if there is wetland modification or filling, contact the U.S. Army Corps of  Engineers, Permit Section.
c. Questions about stormwater management send copies to MWRD.
d. Cook County Highway Department, Drainage & Utility Section or the Township Highway Department should be notified when appropriate.
