Local Project Soliciation

Projects may be submitted to the Regional Water Management Group (RWMG) for inclusion into the IRWM Plan at anytime. Project proponents should use this form to provide basic information about new projects.


Projects must meet at least one IRWM Plan Objective to be considered for the IRWM Plan's Full Project List. Project information will be reviewed to evaluate the projects; additional information may be requested as needed.


At a minimum, this Full Project List will be submitted annually to the RWMG for approval. Special circumstances (i.e. Grant opportunity, Plan Update, etc.) may necessitate a Full Project List update and those situations will be handled on a case-by-case basis. In any case, a submitted project might not be immediately be incorporated into the approved Full Project List.
