Stewardship Incentive Program (SIP)

The stewardship Incentive Program (SIP) is a voluntary, “mini-grant" program for Lewis County landowners, provided by the Lewis County Noxious Weed Control Board (LCNWCB) with the goal of providing financial assistance to landowners in their efforts to control high priority noxious weeds, as identified by Lewis County. Through a simple application process, LCNWCB will provide site specific noxious weed identification, consultation on appropriate control measures, and reimbursement of up to 75% for the cost of approved herbicide(s), hiring a contractor, or tool rental, up to $500.

Introductory materials, offering all the details you need to navigate the process, can be found here 2026 SIP Program: Introduction. Please review these instructions in their entirety.

To apply, please fill out the 2026 SIP Application to the best of your ability and submit it back to us via email or paper mail.

We are also able to offer reimbursement for pesticide application licensing. This application is available here 2025 SIP Pesticide License Reimbursement Application

Residents may participate in both aspects of the program simultaneously. Acceptance into one will not negatively affect the application status for the other.

Please Note: A "W9" will be required before reimbursement is distributed. Please make sure to fill out this form and submit it with your receipts if you didn't submit it with your application.
