Technical Advisory Committee - Public Meeting, 6-10-26

The McHenry County Technical Advisory Committee held a public meeting on June 10, 2026, focusing primarily on proposed amendments to the Stormwater Management Ordinance (SMO). Key procurement-related discussions included updates to permit application requirements, particularly regarding wetlands and jurisdictional determinations, and revisions to runoff rate reduction and stormwater attenuation standards to incorporate green infrastructure practices. The committee reviewed simplified methods for runoff calculations, including curve number tables and compaction factors, aiming to streamline permit submittals and improve consistency. They also discussed new provisions for solar farms, defining impervious and pervious areas under solar arrays and establishing native vegetation performance standards with enforcement mechanisms. The meeting addressed long-term maintenance requirements for stormwater management facilities, potential certification programs, and coordination with municipalities for enforcement. Additionally, the committee previewed upcoming watershed planning RFPs and shared flood event data and mapping tools. No specific contract awards or vendor selections were mentioned, but the discussions indicate future procurement opportunities related to watershed projects and stormwater infrastructure improvements.
