Following the tragic wildfires of October 2017, the Sonoma County Board of Supervisors directed Sonoma Water to explore the possible extension of sewer service to residents of the Larkfield Estates neighborhood who lost their homes in the fires.
The Airport/Larkfield/Wikiup Sanitation Zone (ALWSZ) is owned and operated by Sonoma Water to collect and treat wastewater. Sonoma Water is planning to (1) make sewer service voluntarily available to current property owners within the ALWSZ boundary that were impacted by the Tubbs Fire, and (2) provide low cost financing for property owners wishing to connect. It is anticipated that sewer service will be available in 2020. Permit Sonoma has indicated that 'properties with compliant septic systems will not be compelled to connect' to the new sewer system. For more information please visit the Permit Sonoma website at www.sonomacounty.ca.gov/Rebuild/Permits/Well-Septic-Sewer/.
On Feb. 5, 2019, the Board of Directors of Sonoma Water approved the Larkfield Estates Sewer project, which will bring sewer service to willing property owners in Larkfield Estates. The Board’s action starts the clock running for property owners to participate in the sewer project. Participation in the sewer project is entirely voluntary.
Permit Requirements: Once construction and sewer system testing is completed, Sonoma Water will send a letter to property owners giving the “green light” to connect to the system. At that point property owners will need to secure the below three permits from the Sonoma Resilience Permit Center:
The permits do not require mandrel testing as previously stated in a letter issued by our organization to you last month.
Construction update: Construction is now complete on all phases.
The costs for design and construction of the new sewer system in the public streets would be paid for by the ALWSZ and then allocated to each parcel within the area served by the sewer collection system.
The bids for construction of the Larkfield Estates Sewer Collection System project were opened on September 17, 2019 and came in well below our previous estimates. While the precise amount that will be used for the signing of final documents by property owners is still being calculated, we can announce that this cost will not exceed $42,000.
The actual costs will be determined based on actual sewer construction costs.
View the October 2, 2019 Community Meeting presentation, which explains the cost schedule.
In addition to each property owner’s share of construction costs, property owners connecting to the sewer system will pay a connection fee and an annual sewer service charge:
Property owners in ALWSZ will have the option of a 20-year, 2% interest loan, to pay connection fees. The estimated annual connection fee loan payments, based the FY 2018/19 Connection Fee ($11,940), would be about $731 per year. An Accessory Dwelling Unit of up to 1,200 square feet would pay a connection fee of $9,552.
The loans will be secured by a lien against the property and shall be repaid over a period not to exceed 30 years for the construction and design costs, and 20 years for the connection fees.
If participating in the financing program for construction and connection fees, please consult your mortgage holder as the financing is considered a lien on your property, much like a property assessed clean energy (PACE) loan. Sewer financing will not subordinate to your mortgage.
Construction of the sewer system is expected to begin in December 2019 and be completed by August 2020.
Construction costs per parcel will be determined by September 24, 2019 when the lowest qualified bidder for the project is confirmed.
Participation in this project is strictly voluntary. There is no requirement to connect to the sewer upon transfer or sale of the property. Property owners who have functioning septic systems approved by Permit Sonoma may continue to use those, subject to requirements of Permit Sonoma.
However, if property owners choose not to participate at this time, future connection to the constructed sewer collection system will be possible, but financing under this program will not be available at that time:
