Implementation of Ordinance No. 3413 regarding wastewater service charges for the Los Osos Wastewater System

While Ordinance No. 3413 was adopted by the Board of Supervisors on April 20, 2020, the rate increase was postponed until 30 days after the County Emergency Proclamation has been terminated. This delay has resulted in the wastewater system taking on more debt to cover the revenue shortfall. Additional impacts include the inability to build financial reserves and implement planned capital improvements.

The State of California moved beyond the Blueprint for a Safer Economy on June 15, 2021 and most sectors have returned to normal operations. Following a year of deferment, the staff recommended implementation of the wastewater service charges scheduled for the Fiscal Year 2021/22 was approved by the Board of Supervisors on June 22, 2021. Ordinance No. 3413 is in full effect on July 23, 2021. 

At the Public Hearing on August 10, 2021, the community will have an opportunity to review the rates and charges that will be added to their property tax bill for Fiscal Year 2021-22.

For customers experiencing hardship in paying utility bills, Federal funding is available for eligible tenants and landlords to assist with unpaid rent and utility bills between April 1, 2020, and March 31, 2021 through the CA COVID-19 Rent Relief program.

August 27, 2019: Valve Turning Ceremony for the Sea Pines Golf Resort Recycled Water Connection Proposed Los Osos Sewer Rate Increase - Public Hearing Information

There will be a valve turning ceremony to celebrate the completion of the first recycled water connection from Los Osos Water Recycling Facility to Sea Pines Golf Resort.  The event will take place on Tuesday, August 27, 2019, at 10:00 a.m. at Sea Pines Golf Resort intersection of Glenn Street and Howard Avenue in Los Osos and will include light refreshments. The Los Osos Water Recycling Facility was designed to deliver highly treated wastewater for irrigation and other purposes to promote sustainability within the Los Osos Groundwater Basin. Sea Pines Golf Resort is the first connected to receive recycled water for irrigation use since the plant began operation in 2016. The recycled water they receive supplements up to 200,000 gallons of groundwater water per day, which would otherwise be pumped from the Los Osos aquifer. Additional recycled water connections are planned for other high demand water users.
