* Does not include GWMA Administrative Fee and Indirect Administrative Fee (approved by GWMA Board annually).
Notes:
• The LSGR Watershed Group will determine and approve a budget each year for the following fiscal year necessary to comply with the MS4 permit(s).
• The average Watershed budget for the next four years is anticipated to range between $656,984.85 and $795,297.45, (Average = $726,141.15) depending on the potential for a new regional MS4 Permit to go in effect, plus GWMA administrative fees. The current MS4 Permit is scheduled to expire on September 11, 2026. The watershed budgets may be higher if reassessments of the Watershed Management Program (WMP), the Coordinated Integrated Monitoring Program (CIMP), and the Reasonable Assurance Analysis (RAA) are required for the new Permit.
• Other agencies may participate upon approval of cost sharing agreements by the L SGR Watershed Committee and GWMA. Future participants shall be assessed a late entry cost as if they had been a participant from the beginning of the Metals TMDL MOU, as of March 1, 2012, unless otherwise determined by the LSGR Watershed Committee.
• Watershed Permittees and the cost share are subject to modifications due to, but not limited to, changes in the number of participating agencies, refinements in mapping, and changes in boundaries.
• LACFCD’s annual contribution shall not exceed $100,000 unless otherwise amended.
