Q:        Why am I receiving a notice entitled “Notice of Public Hearing Regarding Sewer Service Charge Rate Increase”?
A:        All property owners within Castro Valley Sanitary District (CVSan) boundaries received this notice for each property that they are identified as the property owner.  The property address is printed in the upper right corner of the notification letter (ex. “Re: 12345 Main Street”).

Q:        What does this notice mean?
A:        The notice is a requirement for Prop 218 (Cal. Constitution Articles XIII C & D), in which CVSan must notify property owners when: a rate increase is being proposed, the amount of the rate increase, and the basis for the rate increase. This information can be found in the notification letter you received.

Q:        Why are you increasing the sewer service charge rates?
A:        CVSan has determined that rate increases are necessary to enable the District to: (1) recover current and projected increases in the costs of operating and maintaining the sewer system; (2) construct capital infrastructure improvements needed to repair, replace and update the District’s aging sewer system; (3) fund new capital infrastructure; (4) maintain the operational and financial stability of the utility; (5) avoid operational deficits and depletion of reserves; and (6) comply with state and federal regulatory wastewater treatment and disposal requirements. The proposed fees include costs of customary goods and services used by CVSan, which have increased by an average of 3%; and are consistent with the Bay Area average for cost of living adjustments. 

CVSan is proposing to budget and spend approximately $7,801,085 during the next two-year budget cycle on vital improvement projects.  CVSan plans to spend about $6,835,000 on the wastewater collection system, including gravity sewer rehabilitation, trunk sewer capacity projects, the Lateral Replacement Grant Program, and new large sanitary service cleaning equipment.  CVSan will pay $457,714 for treatment plant capital improvement projects.  The proposed increases will continue to position CVSan with one of the lowest rates in Alameda County, as well as throughout the Bay Area.  Additionally, the rate continues to be lower than the average annual service charge in the State of California.  

Q:        What should I do if I agree with the proposed rate increase?
A:        If you agree with the proposed increase in rates for sewer service charges, no action is necessary.

Q:        What should I do if I don’t agree with the proposed rate increase?
A:        As the property owner identified to be subject to the proposed rate increases, you may submit a written protest in opposition of the proposed rate increases.  If the identified property has more than one owner, only one written protest will be counted.  To qualify, each protest must:

·         Be in writing.
·         State that the protest is being submitted in opposition to the proposed rate increases.
·         Provide the location of the identified property (by street address or APN).
·         Include the original signature of the property owner submitting the protest. 

Written protests may be submitted by mail or in person to: Castro Valley Sanitary District, 21040 Marshall Street, Castro Valley, CA 94546, or at the public hearing on May 23, 2017 at 6:30 p.m., and must be received prior to the conclusion of the Public Hearing.  Any protest submitted via e-mail or other electronic means will not be accepted as a formal written protest.  Please identify on the front of the envelope for any protest, whether mailed or submitted in person, that the enclosed letter is for the Public Hearing on Sewer Rates.

Q:        If I submit a protest letter, do I still have to pay the increased rate if it is passed?
A:        Yes, you will still be required to pay the increased rate even if you submit a letter in protest.

Q:        Who do I talk with about the Public Hearing?
A:        Call CVSan at 510-537-0757 extension 106 or email board@cvsan.org.  The Public Hearing will be held at the Regular Board of Directors Meeting on May 23, 2017 at 6:30 p.m. in the CVSan Board Room, located at 21040 Marshall Street, Castro Valley, CA 94546.  The Public Hearing is a public meeting and is open to the public.  Members of the public may speak for three minutes.  Oral comments at the Public Hearing will not qualify as formal protests unless accompanied by a qualifying written protest.  CVSan offices are open Monday-Friday 7:00 a.m. – 4:00 p.m.   

The purpose of the hearing is to consider all written protests against the proposed rate increases to rates for sewer service charges within CVSan boundaries.  Please review the notice for guidelines for what constitutes a qualifying written protest.  Protests submitted by e-mail, facsimile, or other electronic means will not be accepted.

Q:        When was the last time CVSan sent a Prop 218 notification?
A:        A Prop 218 notification of rate increase for sewer service charges was mailed to all property owners within CVSan boundaries in March of 2015 for rates effective July 15, 2016 and July 1, 2017, and the Board of Directors approved maximum rates through June 30, 2017. 

Q:        I lost my notice.  Can I get another one?
