MSD Project Clear is seeking contractors to join the Participating Contractor List  for design and installation are reimbursable to grantees if a participating contractor was used. For more information, please see the Contractor Application and Contractor Guide. 


Project Clear is MSD’s initiative to improve water quality and alleviate many wastewater concerns in the St. Louis region. MSD will invest billions of dollars over a generation for community rainscaping projects, system improvements, and an ambitious program of maintenance and repair. Rainscaping investments alone will total $100 million.  Last season (2016-2017), over 100 applications were selected to receive grant funding, totaling more than $300,000.  Please let us know if you would like us to visit your community event to talk about the Rainscaping Small Grants Program!


Location –   Please see if your property is located within the Rainscaping Grants Program Area.

Orientation –  All applicants are required to attend at least one Landowner Orientation Session within the current (2018-2019) or previous (2017-2018) program year.  REGISTRATION FOR THE 2018-2019 ROUND LANDOWNER ORIENTATIONS IS CLOSED.  If you are interested in participating in a future grant round, please send your name, phone number, email address, and the mailing address of the property you are looking to apply for, to or call 314-577-0202 and you will be placed on a confidential list to be contacted with information for next year.


Grant Amount –  If approved, landowners within the Program Area can be reimbursed up to $3,000 for rainscaping projects.

Plan Help –   Applicants may seek bids and advice from contractors. Costs for design and installation are reimbursable to grantees if a Participating Contractor was used.  Don’t forget to plan for maintenance, such as watering plants, weeding, pruning, and mulching.

Approval –  Applications will be competitively scored. Priority consideration will be given to projects that manage a large amount of stormwater. Additionally, projects that propose a high percentage of native plants, are cost effective, well designed, available for outreach, and have a detailed maintenance plan, will all be considered in the approval process.

Boulders – Decorative boulder expenses, or rock work that is not serving the functionality of the stormwater feature, will be capped at a 10% aesthetic cost maximum reimbursement for approved applicants.

Multiple Grants – Multiple grants may be submitted under the following criteria:

  • One (1) grant is permitted per residential address.  No additional grants will be awarded for residential addresses that already have received grants in previous years.
  • Up to four (4) grants are permitted per commercial address. No additional grants will be awarded for commercial addresses that already have received the maximum number of grants in previous years.
  • Each individual address counts as a separate property, excluding individual buildings that have more than one address.
  • One (1) representative must attend a Landowner Orientation Session within the current (2018-2019) or previous (2017-2018)  program year for each property or organization with multiple properties.
  • For multi-family or duplex properties with a single property owner, you may submit an application for the total number of units (up to 4).
  • If there are multiple owners, EACH OWNER may submit one (1) application, totaling up to four (4).  *NOTE – We do not recommend applying for a Green Roof for shared ownership of a multifamily home.
  • Each grant must be for a unique project, and each project must meet minimum requirements, as applicable. For example: a rain garden covering 100 square feet – would be one grant. A lawn alternative and pervious pavement area with a combined area of 100 square feet – would be a second grant. A large rain garden covering 200 square feet – would only be one grant.


  • Applications must be received by August 1, 2018.  
  • Participants have two time frames in which to complete their projects:
    • Fall planting period is September 10, 2018 – October 31, 2018
