Private Property Drainage Assistance Program
Program Information

Private Property Drainage Assistance Program

The City of Warrenville has created a Private Property Drainage Assistance Program for residents. The program allows owners of single-family residential properties to apply for City assistance to help alleviate storm water and/or surface water drainage issues on private property. 

Participation in this program is based on a first come, first serve basis. Availability of funds for each fiscal year and proposed projects will be considered in accordance with the City's fiscal year budget (May 1 to April 30). Any funds provided under this policy shall be subject to such budget limitations and other restrictions, as set by the City. The City will maintain a rolling list of projects that will be considered for funding, and reserves the right to require applicants to update their application materials from time to time. 
Program Requirements

In order to be eligible for the program the following requirements must be met:

  • The proposed project shall involve at least four single-family residential homes located within the corporate limits of the City of Warrenville.
  • The proposed project shall demonstrate a need to address standing water issues with a documented duration of at least 48 hours. 

Projects not meeting the above criteria shall not be eligible for the program; however, City Council reserves the right to consider such projects, if staff presents a recommendation for discussion and City Council consideration at a committee of the whole meeting. For those projects not approved, City staff will still provide advice to the property owner. 

Application Fee
Each application will be charged a fee of $500. The purpose of this fee is to cover the initial cost for staff to visit the site, develop a scope of work, and a conceptual plan and estimate of design and construction cost for each application, for purposes of calculating cost-benefit and evaluation of the budget implications. 

Example of Possible Solutions

Option 1: Re-grading yard(s) to reestablish proper pitch.

Project improvement should minimize future maintenance requirements. Re-grading the yard(s) by utilizing a combination of filling low areas with soil and removing high points along the drainage profile where appropriate requires less future maintenance than other improvements such as the installation of storm sewers.

Option 2: Private gravity storm sewer installation.

In instances where Option 1 is not viable, installation of a storm sewer to drain a low area may be the appropriate option. This option also requires that a receiving storm sewer is available in the vicinity of the problem area. This might be an existing rear yard storm sewer system in close proximity to the problem area or a storm sewer system in a near street the subject property that can be accessed by extending a storm sewer/drain to the street via a side or rear property line. A gravity system is one that maintains a positive pitch and drains via gravity to the receiving storm sewer system without the aid of a sump pump.

The City will be responsible for maintaining the storm sewer main and connections. Property owners will be responsible for the maintenance of landscaping as well as any pipe from the connection point to their sump pump or other individual facility on their property.

Evaluation Process

City of Warrenville staff will consider the following factors when evaluating project(s) each year of the program:

  • Locations where flooding also occurs in the public right-of-way to the degree which the public roadway must be closed to traffic; no structures are adversely affected.
  • Flooding conditions where flooding is limited to private property of at least four, contiguous, single family residential homes; however, no structures are adversely affected.
  • Located in a development constructed before the modern Countywide Stormwater Ordinance was adopted in 1992.  These developments would not have been subject to the same level of regulation or City inspection as developments constructed after 1992.
  • Number of sump pumps connected to the sanitary sewer.  These connections are illegal and the City is seeking opportunities to eliminate these connections and provide a storm sewer to receive the sump pump flows instead.
  • Cost-benefit of a project will be calculated simply by dividing the total cost of the project by the number of benefitted properties.

Other criteria during the evaluation process shall include the severity of the drainage issue, number of project applicants, location of the drainage issue, type of drainage damage and duration of the drainage issues. Project prioritization is one of many criteria considered during the process. City staff will rank the projects utilizing a consistent ranking system to ultimately decide which projects will be considered for funding during any individual funding year. 

The first round of applications will be accepted through May 31, 2019. Applications sent after this date may not be considered in 2019.
