NOTICE OF PUBLIC HEARING
NOTICE IS HEREBY GIVEN that the City Council of the City of Carlsbad will hold a virtual public hearing at 5 p.m. on Tuesday, Jan. 11, 2022 to consider approving three-year rate increases for potable water, recycled water, and wastewater services. Those wishing to protest the proposed rate increases must submit their concerns in writing to the office of the City Clerk any time before the close of the public hearing. You may hand deliver your written protest or mail it to City of Carlsbad, Office of the City Clerk, 1200 Carlsbad Village Drive, Carlsbad, CA 92008.

In order to be counted, protests must be signed by the property owner or ratepayer and include the protester's printed full name and the specific rate being protested. Only one protest notice is allowed per parcel. Emailed protests do not satisfy the signed written protest requirement. If a majority of ratepayers protest the increase, it will not be passed. You are welcome to speak at the public hearing, but official protests must be made in writing. Consistent with SB 323, which was signed into law in late 2021, any judicial action challenging these fees for water or sewer service shall be commenced within 120 days of the date of the resolution approving the increased rates.

In the interest of public health and safety, we are temporarily taking actions to prevent and mitigate the effects of the COVID-19 pandemic by holding City Council and other public meetings online only. All public meetings will comply with public noticing requirements in the Brown Act and will be made accessible electronically to all members of the public seeking to observe and address the City Council. All comments received by 2 p.m. the day of the meeting will be shared with the City Council prior to the meeting and all protests that satisfy the requirements above received by the clerk's office before the close of the public hearing will be counted. However, any comments received against the proposed rate increase will not be counted as protests unless they each satisfy the protest requirements described above. Written comments will not be read out loud. If you wish to participate virtually, you may visit:
https://www.carlsbadca .gov/city-ha II/meetings-agendas for meeting instructions.

Copies of the staff report will be available on and after Jan. 7, 2021. Those persons wishing to speak on these proposed rate adjustments are cordially invited to attend the public hearing. If you have any questions about how to protest the proposed rates, please visit carlsbadca.gov/rates . If you have any questions about the rate adjustments in general please contact Vicki Quiram, Utilities Director/General Manager of the Carlsbad Municipal Water District at (760)-438-2722 or [email protected] .

To: The Citizen Elected Members of the Carlsbad City
Council:

We are submitting as directed by the written paper
notice of the Carlsbad Municipal Water Districts, a
protest letter to OBJECT STRONGLY to all three
proposed water rate hikes upcoming in March 22, January 23, and January 24. Reason: We are the only city in
California to have a working water desalinization plant (thank you Bud Lewis) that was approved by the Coastal
Commission to more than adequately supply water for
future needs in our area. The small country of Israel with only 170 miles of coastline has 31 desalinization plants.

We are UNFORTUNATE enough to endure and pay
for the State Governor's mistakes, who was advised by an EXPERT in water conservation for future demands, to
build more collecting reservoirs for water use. HE DID
NOTHING and all along the coast, cities can build water desalinization plants (like Santa Barbra), to supply theirs and their inland neighbor's needs.

DO NOT raise our rates. Carlsbad can be an example
of self-sufficiency to other municipalities along the coast.

All this state does is RAISE rates to pay for other non related issues while those who work hard give hand-outs to decision makers such as yourselves ( citizen elected council members). You tell us you need it for pipe repair.

Why now, we have had the pipes for a long time. You are like the State who repeatedly asks for gas tax hikes for highway repairs only to never use the funds for highway repair but for more give outs to people who don't work.

DO THE RIGHT THING, announce you don't need
to GOUGE the public anymore this difficult year. NO
RA TE HIKE!! Be a good example and set the example,;
don't raise rates and announce it. Because we in Carlsbad do BETTER at management than the average city. NO
rate hikes because we have a water desalinization plant.

NO RA TE HIKES BECAUSE INFLATION IS KILLING
US FROM EVERY OTHER ANGLE.

We are submitting a written protest to the proposed wastewater increases for single-family residents. The exponential increases over three years will hit families the hardest because there is no way to pass these expenses on to others like businesses or multi-family residential setting can. The flyer has a graphic of three green bills that states that even after the rates are approved, "Carlsbad will still have among the lowest wastewater rates in the region". Where is the data to support this? What is the "region" this statement is referring to? Where is a table of the current and proposed rates in the "region" mentioned?
This increase comes out of NOWHERE, with no warning, and very little time to digest, research and protest. It is interesting that this HAS to be done now, right after the holidays. I feel like the city is hoping people will overlook this because they are busy with family and friends.

We would like to see the protest deadline pushed back into February. We would like to have more information about this. We would like to see the research that went into deciding the increases. An increase is fine - an increase that will have each household paying $300 more per year in three years is ludicrous. We are discouraged that our city operates this way.

CITY CLERK'S OFFIC E
January 7, 2022
I have been a resident of Carlsbad for 31 years, and a home owner since 1992. This is a first for me to even have to respond with a letter of protest. Never have I seen the proposecl rates jump the amount of percentage points as the current proposal suggests. First off, I can't believe there are 17 different published customer class rates. That i s very confusing to keep track of, especially when trying to figure out the amount of wastewater created by different groups of people, not to mention what the Customer Class "Other" represents. It may be the agenda for the City to disguise and figure out how to railroad this in order to sell it to the public, but in reality it is not that simple, not easily understood and doesn't make any sense. Really, are you able to figure out the wastewater stream of a Junior High student to justify a higher rate than that of an Elementary student or a High School student? We all should be paying a more equal portion on an easy, simple, and fairly calculated method. A home owner that sits at a brewery all day and uses their toilets is paying a Residential rate and the brewery is paying a different rate which is passed on to their customer. That customer is paying for little use at home, but is still paying, plus is paying at the brewery, too . A toilet flushed from an Elementary student is still equal to a toilet flushed from a Junior High student and so on. Are you going to breakdown figures by gender, also?
I see by the published pie chart that the costs for Depreciation, Operation and Maintenance of the system are less than 50%. There are also little icons of a worker, and an excavator, symbolizing some share of regional operations and projects. Odd, those regional operations and projects aren't readily broken down with details for the public awareness as to costs and what is proposed to be done. Rates should not be put in place on ambiguous information, especially when more than 50 percent of the costs are not openly revealed.

Lastly, the compared breakdowns of proposed rates for all the classes vary from the lowest increase of

3.79 to the highest 21.88 percent, just for the year of 2022. In 2023 the class comparisons vary from of

19.72 percent to a high of 21.35. The year 2024 shows the low percent increase of 19.88 percent to the highest of 20.47 percent. If one just adds the three increases proposed just for a Single Family Resident, which happens in a two year span, the total increase comes to 75.27 percent. If rates are passed, 2024 will see a increases that vary from 49.48 percent to 75.86 percent, all in just two years. That's wrong .

I cannot support rate increases of this magnitude. These proposed rates are inflationary and are beyond any reasonable request. I can support up to a 3 or 4 percent increase but not 75.27 percent. That is more than inflation and all the other cost increases creeping up. As a business owner, I couldn't justify my goods and services going up that much, I would be out of business in short order. Get back to a fair and simple to understand rate for all. I deeply protest these proposed rates fo r sewer increases. Water rate increases are somewhat in line and not an issue - YET. ~~ ~)!7~ cfbr.

ESTIMATED 2022 WATER BILL

SOME CONTROL

VERY LITTLE CONTROL

ADDITIONAL COST DRIVERS
• Aging infrastructure throughout the city’s and the Encina Wastewater Authority • Delayed project implementation by Encina, resulting in higher construction costs • Decreasing wastewater volumes associated with water conservation are causing higher treatment costs due to more concentrated wastewater that is harder to treat
• The wastewater authority’s decision to pay off 100% of the CalPERS retirement liability in three years, while other agencies choose to remain closer to 80% funded (City of Carlsbad) or payoff the liability over a longer time span • The wastewater authority’s $95 million of capital requirements for infrastructure budgeted over the next 10 years
• Materials such as steel, copper, chlorine and odor control chemicals have not only risen in cost but are now difficult to obtain

RESERVES
• Past rate increases included the use of reserves, but much of those reserves have now been allocated to the updated Sewer Master Plan. • In the FY 2021-22 budget for wastewater, there is an estimated $24 million in capital reserves, however $35 million is needed to execute the Sewer Master Plan, creating a $9 million deficit.
• City and CMWD staff are developing a reserve policy for potable water, recycled water and wastewater, which will be in line with industry standards.
• Potable water capital funding is sufficient for planned projects.
