City Manager Biggs then spoke of the City’s recognition of Ms. Flores’ service at the Summer Picnic where she was presented with a proclamation, a crown, and lei given the Hawaiian theme of the event.
E. PUBLIC FORUM
Michael Kirby said he has lived in Orinda for 10 years and he spoke of his declining health, stating there are only 3 disabled spaces near the theater and he suggested the City add more disabled parking spaces throughout the City.
K. MATTERS INITIATED
Councilmember Iverson said economic development and downtown revitalization are something they talk about a lot and are one of their high strategic priorities. She has heard about one space downtown on the Theater Square side has had several potential tenants and, because of the City’s parking regulations, the tenants wound up not being able to make a deal moving along.
The rules are that if it is a nail or hair salon, 2 parking spaces are needed for every station, and when they are told to either buy it out with an in-lieu fee or to provide those spaces such as for 6-8 stations, this is going to be 12 to 16 parking spaces of street parking right downtown. If those tenants or landlords cannot provide that they cannot have those businesses. What they have been told is just to have fewer stations which feels tone deaf about fixing problems downtown.
She has asked questions about what can be done about it and has been told that because they have the choice of going before the Planning Commission to get a variance on the parking requirement, the only alternative with this is to pay the in-lieu fee which can be very expensive. These businesses have to choose between either scaling down to where it is not feasible or paying a parking fee that is infeasible or finding parking that is infeasible.
She would like the Council to consider a period of time where the City might waive or significantly reduce the in-lieu parking fee in the downtown core for change of use of existing businesses. If there are vacant spaces downtown and they want to get a different use in there, if it is within the next 12-18 months the City gives them a break on the parking fee so they can go before the Planning Commission, get that change of use, and get the variance in a way that will not be a deal-killer for these types of small businesses. It should also apply to retail and restaurants as well. This can be an incentive to recruit and attract some businesses into some of the long-term vacant spaces.

Said motion carried by unanimous (4-0) roll call vote.

Item Removed from the Consent Calendar:
F.3. Response to Grand Jury Report No. 2306, Affordable Housing Recommendation:
Approve the City of Orinda Response to Grand Jury Report No. 2306, Affordable Housing.
Councilmember Iverson commented that she thought the Grand Jury Report itself was an interesting analysis of the Housing Element and it felt more accurate than some aspects of the Housing Element. She thought the Response Letter was very thoughtful, well done, and accurate. The one thing that felt missing was the RHNA numbers themselves and it seemed like a given that those RHNA numbers were acceptable.
What the Council hears the most is how upset people are at the growth numbers that are forced upon the City. Adding density in the downtown and existing neighborhoods concerns people, especially for fire safety. While the letter did a good job of mentioning the fire safety in two places, she thought somewhere the fact of getting the RHNA numbers was done so unilaterally that the City had to work entirely within that paradigm including a portion of affordable and very affordable income levels along with the absolute numbers.
Mayor Miller opened the Public Forum, and there were no speakers.
Mayor Miller agreed with Councilmember Iverson’s comments and she asked and confirmed that Councilmember Iverson said the RHNA numbers were not mentioned at all along with the process by which they are assigned. She felt the whole premise of the report and response is about how the City deals with those numbers. And, from a wildfire safety standpoint, the numbers given are too high.

City Manager Biggs said he thinks this point is made about fire and the conflict in State law in the report. He thinks not covered at all is the RHNA allocation process. He suggested this go at the end of the introductory letter to state it was not addressed in the report of how RHNA numbers are determined and allocated, that there is not a lot of input from local government, and they do not factor the competing constraints into it. Staff can include such a paragraph. This is due on September 13th and staff could add it or delegate it to the Mayor’s finalization and signature of the transmittal letter.
Mayor Miller and Councilmember Iverson agreed to delegate it to staff as provided by the City Manager and to also comment on the appeal process. There were a certain number of RHNA units applied throughout communities and if Orinda had been successful in an appeal, those housing units would have been delegated to one of their sister communities. This was a factor with the City deciding not to appeal the number.
Mr. Biggs stated the League on a statewide basis is starting to look at the next RHNA allocation process. The State is conducting outreach and the League is engaged. There are still cities without certified Housing Element that are 3-4 years in and so Southern California will receive allocations in the next year or two. Staff will continue to weigh in on that as well.
MOTION by Councilmember Iverson, and seconded by Vice Mayor Gee, to approve Consent Calendar Items F.3, as amended, to make additions to the cover letter.
Said motion carried by unanimous (4-0) roll call vote.
G. PUBLIC HEARING – None.
H. POLICY MATTERS
H.1. Moraga Orinda Fire District Proposed Ordinance 23-08 Regarding Fuel Break Requirements on Certain Parcels in Both the State Responsibility and Local Responsibility Areas within the Fire District Recommendation:
Receive Report, Discuss, and Provide Direction, if any.
Mayor Miller explained development of the ordinance and timing for the Council to discuss comments. They have the ability for the public to provide comments and she felt MOFD board members and staff did want to hear the City’s comments but they were not able to provide it timely, and this is why she has asked that it be on the agenda.
One thing she was concerned about was the landslide potential and removing of vegetation on the hillsides because those serve as protection against erosion. Also, as they are 4-5 years into hard work on vegetation removal, many areas are left bare. Those are either getting very dry, the soils are no longer retaining water, and she is seeing many invasives sweeping around town, Lake Cascade, streets, and private properties.
F.1.a

Attachment: City Council Minutes of September 5, 2023 (3208 : City Council Minutes) Orinda City Council Minutes Page 7 of 19 09.05.23
The Fire Chief reviewed the comments and indicated he has no problem proposing to his board that the same requirements in the fuel ordinance that has already been in effect this year, with regard to trees less than 15 feet, he could propose they just be limbed up one-third.
Lastly, because this was not the normal process of initiating it, staff may not be able to provide much information about the ordinance. The ordinance covers all of the districts which are communities at risk. The ordinance applies differently on parcels less than 1 acre than on 1 acre or more, applies to the entirety of the parcel if the parcel is less than 1 acre. If it is applying to a parcel more than 1 acre, it is 100 foot buffer around the property.
She personally had a concern about street trees downtown which the City Manager worked to keep from the PG&E work. There are some codes whereby if a building is proposed there, the tree would have to come out as parcels are developed unless the parcel is developed and uses alternative means for purposes of getting ladders there.
She would like clarity from MOFD on where they can find that exact code and see how they can work with this or around it to ensure street trees are not removed.
Vice Mayor Gee said staff has seen a lot of correspondence the Council has received, and she suggested staff comment around the common themes.
Mr. Biggs said it was towards the end of last week when staff recognized there was going to be a special meeting of the Fire Board this week to consider introduction of this ordinance. The reason is because they are not currently enforcing Ordinance 24-04; the fuel break ordinance which has been suspended. They can only introduce a matter at a special meeting and cannot adopt. Their goal was to be able to adopt the ordinance to get provisions back in place.
Staff is not expert in these areas but have become more familiar over time. Part of what they tried to do quickly was to compare the prior ordinance which was approved in February to see if there were changes to it. There were in a number of areas and there is some new language talking about slopes and what is needed, revisions to definitions of fuels in a few other things, they have clarified and broadened a modification process, added more substantive language of what is involved in modification and how to apply, clarified modification is something that can be appealed to the Fire Board.
Often times, more detailed language is added from the State Fire Code they look to for guidance on some of these things, and the Chief has been deployed the last 10 days for fires on the Oregon border but to the extent the Council and the public have comments, they can be passed on. If the Fire Board adopts at their second meeting, there could be some modifications, and if not heard, it would be put off until October.

Councilmember Iverson said she thinks of the MOFD residential and downtown areas as voluntary home hardening and she thinks of a fire break as a perimeter that is the protective layer between the wildland and the City. This, however, defines all of Moraga and all of Orinda as a fire break, every house, every yard of both cities is a fire break.
The significance of that for all landscaping and grasses, trees, and critters is extremely significant. She asked and confirmed with Mayor Miller this is what she is saying.
Mayor Miller said this is her question as to what MOFD means as “fuel break”. This ordinance and there is Ordinance 23-03 which was used this year. There is a provision in 23-03 that says if there is a conflict between 23-03 and 23-04 or its successor, the more constrictive of the part of that law applies. So, this proposed ordinance talks about allowing vegetation on lesser sloped hillsides. For more steeper hillsides it is more constrictive. So, she was unsure of their thoughts.
Councilmember Iverson said it is a paradigm shift for a City that has so much natural beauty and animal life. There was a lot of thought put into exceptions for things like animals and streams, but it feels the default is that everything is to be cleared unless you can argue for it to be retained.
Mayor Miller said she spoke with Assistant Chief Haley today from EBRPD and he wanted to make sure that he was happy for her to let people know that if there are other public agencies that wanted to use their modification, he was happy to provide that as a template because they went back and forth with MOFD with different types of proposals as to what could be a modification, etc.
Councilmember Riley asked if the modification section is based on the State ordinance or if it is unique.
Mayor Miller said it is unique and Assistant Chief Haley said their template that EBRPD created was approved by MOFD. He shared that he was happy for their work to serve as a template because there was no template. They had to figure out how to seek a modification. The modification must achieve the same degree at least of fire protection as if it is not applied. They felt they were able to achieve that. However, EBRPD’s template would not be used for a residence because of the different public CEQA processes for that.
Mayor Miller then distributed the Fire Chief’s response to her questions. He said there is a website and he said the modification process and link to submit modification requests are included on this website. This information is included on pre-citation and citation correspondence. Modifications are included in the definition section of the ordinance and explained in Section 5.
Mayor Miller asked for any comments from Councilmembers to provide to MOFD tonight.
They can also ask questions for staff to return with, such as the downtown treescape and how that will work with development. There has been an application; the 25A example related to this.

Councilmember Riley asked if the new ordinance is based on the State ordinance.
Mayor Miller said the staff report does not make any mention of how this relates to what other agencies such as Marin, Oakland or Berkeley are implementing. She asked what communities are already implementing any of the elements of this ordinance, and which elements are taken from this ordinance and implemented there. The Chief said, “This ordinance was developed in consultation with District Counsel, environmental consultants and lawyers specializing in CEQA compliance. I defer to the AHJ’s in the communities referred above about what steps they are taking.” Mayor Miller said she spent many hours reviewing the ordinance and while she is not a land use attorney, but this did not cite other ordinances of local areas.
Mayor Miller opened the Public Forum.
Barbara Leitner said she has worked as a plant ecologist since 1975. Her concerns regarding the proposed fuel break requirements are several. One is they are so broad as to be difficult for a responsible homeowner to implement. They are not clear, her reading is there may be exceptions, but it will be sophisticated homeowners who will know to ask for that. Others may just implement the guidance and not know what they are doing and thereby cause great ecological harm. If fully implemented, she believes the fuel breaks would have a devastating effect on biodiversity in a City that claims to value its semi-rural character and natural resources.
The regulations claim they would ensure there would be no significant impact to rare and endangered species, yet homeowners are left with no information about where those species are. As a consultant to the City on stream resources, she said most homeowners have no idea what the resources are in their own backyard when it comes to streams.
The proposed guidance states there will be no impact and no environmental review which is not the way it is done. She suggested MOFD and the City look at how practical the measures to be implemented are in the way they are currently proposed.
Michael Bowen, President, Friends of Orinda Creeks, thanked the Council for placing this on the agenda. This issue is so crucial and fundamental to who we are as a community and what they are surrounded by. The opportunity to begin this dialogue is so valuable.
When asking people why they moved to Orinda they say the schools and the natural beauty. Sometimes he asks why they stay after their kids are grown, and often times he hears it is the sense of community and the natural beauty. He is happy that the Chief brought up Marin County because that could be a place that is very volatile, very polarized on some issues and, like Orinda, it is full of attorneys and highly educated people. This could make for lively and late Council meetings.
What they decided to do is try to broker a dialogue amongst all community members and encourage participation and discussion because everybody wants fire protection and a fire safe community. There are ways to do it that will leave them who they are when done and in a place they want to live in when done. He is very grateful to Councilmembers in helping to start to engage in this as a community.

Sandy Pearson echoed Mr. Bowen’s comments, said they are appreciative the Council is taking an interest in this subject, as it has been very frustrating. Fire and residents have their priorities which need to be balanced. There are two different committees the City interacts with the Fire District, and this might be helpful in this situation. On the topic of the modifications the Mayor mentioned, she followed the link in the proposed ordinance and the Chief’s answers.
In visiting their website under modifications it states if you are seeking a modification of the standards for environmental or geologic reasons, you need to hire a professional biologist or a professional geologist to evaluate one’s property, write a report, and submit that to the Fire District who will evaluate the professional’s credentials and decide whether to listen to their report. Some neighbors have received modifications and they did not go through this process. This is an example of the confusion and chaos residents are facing as they try to figure out what is going to be allowed. She would like examples from MOFD of examples of modifications made in the past, but was not sure what is technically allowed. The previous ordinance was for 30 feet so if they cannot enforce the present ordinance of 100 feet, they still have 30 feet and there is a trade-off in the severity of the treatment and width of the treatment.
Laura Abrams said she is realtor working in Orinda and she works well with the point of sale ordinance for resale with MOFD. The personnel are prompt, reasonable, and do not slow down the process and she has an excellent working relationship with staff. She applauds implementation of the program, is aware of insurance issues and the importance of reducing fuel loads, and urged consideration of the rule of unintended consequences. She thinks CEQA is great as it addresses collateral issues, but there is not the oversight of CEQA from what she can tell in this process and it is thought to be exempt. So, it falls to the elected body and staff to think ahead of the impact of what is being considered. Her concerns are irrigation of an area and which moves soils, landslides, mention of herbicide use, legal implications and liability, water usage, and an example of removal of the entire creek bank.
Mayor Miller stated the requirements apply to the entirety of the property and they allow a couple of unirrigated plants on hillsides. The other ordinance does not allow any nonirrigated plants.
Kirsty Peter said she would love to see a model of what Orinda and its neighborhoods would look like if all public and private parcels were in full compliance of the suggested ordinances. This would provide wonderful guidance to homeowners who are confused and nervous about what to implement. She is also concerned about erosion and excess irrigation, asked if MOFD has worked with EBMUD to model the increases in expected water usage and impact on supply, and whether MOFD has studied the effects of irrigating dry hillsides.
Vice Mayor Gee noted MOFD’s special meeting is tomorrow night and they are looking to hold the second reading of the ordinance on September 20th, which is a tight timeline.
She asked what realistically can the City provide by tomorrow evening for their special meeting.

Mr. Biggs said he would hope that everyone who commented tonight is also sharing their comments directly with MOFD. The City could package everything received and more importantly, the Council could engage with more of a process with MOFD to understand how this would work. This is, to a great degree, about operationalizing and implementing the ordinance. There was an example in a riparian area where a homeowner cleared this out which requires a mitigation process with regional agencies. The property owner ignored the orange fencing set up which was a “do not enter” area, and sometimes not everyone enjoys a natural setting necessarily.
MOFD has the final say and City staff does not want to give people advice. They have developed some materials with the Fire District which they have signed off on, which he described and staff is working with master gardeners to come up with information that “translates” to a certain degree, but they do not know if MOFD will accept that interpretation or not. He spoke with the Chief regarding this item and he indicated they welcome the input, as they are trying to respond to a particular issue at the moment, but over time, implementation will evolve.
The Council can also agendize a discussion for the next meeting which would be the evening prior to their adoption and report any modifications made based on community and Council input and suggestions.
Councilmember Riley said she thinks they should come up with some recommendations for MOFD for tomorrow night and did not think they should wait until the next meeting. It seems they are rushing through this because of fire season, but all year is fire season to her. They are operating off of Ordinance 23-03 now, and now they are proposing 23-08.
Mayor Miller said she believes the litigation stems from enforcement of 23-04 so it may just be suspended as a result of the lawsuit. Mr. Biggs confirmed.
Councilmember Riley said she thinks they will get a lawsuit on 23-08 if they rush through this, take comments, take into consideration points, and she would recommend they slow down, listen, and avoid another lawsuit. She is sure people will be very upset with 23-08 in addition to those here today. Also, they should have a lot more user-friendly information.
Councilmember Iverson referred to the lawsuit and observed that in reading the correspondence is when you are defending a lawsuit, there is an undercurrent in the communication of MOFD having to make sure they are being consistent with the fact they are in a defensive position. So, they always must say there is not an issue to endangered species or erosion because if anyone has a problem, they ask to come to them and they will issue a variance. It is a convenient and frankly bullet-proof response, but it makes for a difficult approach. The fire break is supposed to protect the City and not be the City. To say they will outlaw vegetation but residents can come and ask for a variance is upside down. What concerns her is the need to maintain a CEQA defense is impacting some of the tone. So, she also thinks this should slow down as heard from speakers.

Vice Mayor Gee said most of the people in this room read and look at ordinances and pay attention to this a lot more than the average resident does. She frankly found this as confusing as anything she has ever encountered in terms of trying to figure it out. It is not easy and she does not see how there can be an expectation. She would hope the MOFD Directors pay attention to how implementation could occur with all the things mentioned. The guidance is so obtuse and people cannot figure it out. One of the concerning things is everyone cares deeply about fire prevention. MOFD cares deeply about fire prevention. She thinks this actually does the opposite of incentivizing people.
The average person would have no idea of how to find a registered geologist and some of the requirements are too onerous.
Councilmember Iverson said she thinks Michael Bowen’s comments were spot on in talking about the need to balance. MOFD has one thing they are measured on which is fire prevention and suppression. The City is measured on the totality and the fact MOFD is the one passing the ordinance and while the Board cares, MOFD by its charter has only one thing to balance. So, she was not sure how the City can comment that if the City is not a partner in this they will wind up with a badly broken unenforceable, unworkable law.
Mayor Miller echoed all Council and speaker comments made. She spoke about an early talk with Fire Chief Winnacker who indicated he is here for fire and not here to look at all of these other community concerns. In her experience, MOFD does listen and is hearing that he was fighting a fire in Oregon, yet he is responding to questions. So, they are looking for input and be a partner. She thinks it would be wonderful to have more community dialogue and thinks people have a mis-impression that they are not going to be treated the same in this process where rules are mushy. There is a real concern that people will not get a variance and she does not think this is accurate. So, she thinks the Council can do some good to possibly hold a meeting with MOFD and Morage Town Council to hold a forum about these things.
Councilmember Iverson said downtown planning went on for 7 years and 40+ meetings for a Downtown Precise Plan, and here is one of the most defining issues of making a very high wildfire risk community fire-safe and a semi-rural, famous for its beauty-City preserved, and this is rushing it in 2 weeks. It just feels like a slower process and it will not be in time for this fire season. Inside of a calendar year they could get there and she suggested broadening the outreach.
Mayor Miller said during the break she drafted a proposed letter and there is a State Fire Code, Section 307 of Title 19. It has exceptions, talks about shrubs, exceptions for landslides, slope stabilization, and she leans towards providing comments to slow it down rather than make specific requests, and asked how other Councilmembers felt.
Councilmember Riley said she thinks the message should be it should be more userfriendly and bring the State regulations into the local ordinance as well to make it easier on the user.

Vice Mayor Gee asked and confirmed MOFD is doing hybrid meetings and have access for people to be remote.
Mayor Miller referred to Title 19 of the California Code of Regulations, Division 1, State Fire Marshal, Chapter 1, General Fire and Panic Safety Standards, Subchapter 1, Administration, Article 3, General Provisions. She read the section on ground clearances, fire breaks, and read, “The section does not apply to single specimens of trees, ornamental shrubbery, or similar plants which are used as groundcover if they do not form a means of rapidly transmitting fire from the native growth to any building or structure.” She said this ordinance does not apply an objective standard but applies the standard as determined by the Fire Code official which is defined as “either the Fire Chief or their appointees.” In a legal sense, it could be anyone and fire ambassadors who are volunteers. So, it is difficult for homeowners to know.
Councilmember Iverson said in listening to this, it reminds her so much of design guideline books in homeowner associations which do a good job of things a lay person has never dealt with before, taking technical standards, and then gives a few examples so people with their design professional can design their homes. So, she thinks this is a great avenue to work with the proposed ordinance and not seem they are trying to totally derail it, and then go that next layer where it gives specific illustrations and examples.
Vice Mayor Gee said she would also like to share with MOFD that the templates are important. She also thinks there needs to be resources provided that the public can tap into. MOFD should have an on-call contract with a geologist, an environmental specialist, or someone that looks at riparian habitats so that anyone with questions or concerns could ask them to help. She did not see that being so onerous for MOFD to be able to have those services as opposed to trying to impose that on individual homeowners, as well as the consistency factor. There should be some consistency in the resources that they allow people to tap into.
Mayor Miller continued reading from Title 19 regarding, “Removal of all bush, flammable vegetation, or combustible growth which is located from 30 feet to 100 feet from such building or structure, or the property line, whichever is nearer, as may be required by the enforcing agency IF he finds that because of extra hazardous conditions a fire break of only 30 feet around such building or such structure is not sufficient to provide reasonable fire safety. Grass and other vegetation located more than 30 feet from such building or structure and less than 18” in height above the ground may be maintained where necessary to stabilize the soil and prevent erosion.”
She said this defines a more typical space for a home and possibly 100 feet if a situation is extra hazardous. This tells people to not remove vegetation that is holding their hillside up. The City has produced lists of plants and other things and promoting these things.
She thinks it would be a good idea to press for a broader community meeting and discussion in order to get that next layer.
Councilmember Riley asked if the proposed ordinance is going beyond what the State is requiring and if so, whether MOFD can require more than what the State requires.

Mayor Miller said she believes that is an open, legal question and in reading the ordinance, she had serious questions about that to the extent she would advise that the Council ask the City Attorney to review this ordinance because it applies to City land.
They also have a legitimate interest from the perception of residents and thinks the City has a fiduciary position to make sure what they are promoting in doing this work and that it is a legal ordinance.
City Attorney Osa Wolff asked if the Council is requesting she analyze MOFD’s legal authority to proceed with the ordinance.
Mayor Miller said it took her a significant amount of time to review the ordinance. It describes many codes that are mostly based on the State responsibility area which she is unsure is for new housing.
Ms. Wolff said she does not have any Fire District clients and so this is not an area she has any prior experience with. She has analyzed their authority as it relates to local modifications of the State Fire Code that resides in the building standards. That comes to the City for ratification and she has familiarity with this. The Council is talking about ordinances that are not in what came to the City for ratification, and she has not reviewed that.
Councilmember Iverson said when the City was dealing with drought ordinances, the question came up of, if the City ordinance was more conservative than the State ordinance, this was the rule of thumb, and that the City cannot be less conservative than the State.
Mayor Miller said the language was talking about the “site pre-construction” so these codes were designed for development of communities post-1991 and for the very high fire severity zone post 2021 and on. So, they were not designed for communities with already established vegetation. Also, the other legal basis may have been described where MOFD was a regulator; that there is an exception to CEQA where a regulator who is acting in a performance of environmental regulation does not have to comply with CEQA. They felt that as a fire agency acting in prevention of wildfire that they constituted a regulatory agency acting in the course of protecting the environment. It appeared to her that this might be a bit of a stretch.
Her point was more for purposes of understanding the pure landscape the Council is dealing with. She asked what are Marin, Oakland, and Berkeley doing.
Councilmember Iverson said she believes Orinda was the only city that got declared an entire fire break. The City is the fire break and not the fire break for the City, so this creates the ability to regulate everything in the City, which does not make sense. She thinks this is a legitimate question—how do City resources best help get to a good outcome.

Mayor Miller said she thinks another alternative would be to have these community meetings where they could look at Marin and Berkeley and then not have to know what the landscape looks like there. They are all very active and she was on a Zoom meeting last week with an Oakland City Councilmember and Orinda is not the only ones trying to get clarity, so there is value getting buy-in so people feel heard and that they end up with a better product that makes them more fire-safe and ensure they avoid unintended consequences.
Vice Mayor Gee suggested that more than digging into the legal issues to provide comments heard from their residents, feedback received, as well as discussion tonight which had definite points of concern which they could raise as legitimate issues. She thinks there could be a lot of legal explorations but she did not think this is for their meeting tomorrow night. She thinks the Council should emphasize that the process is moving too quickly and that there is a great deal of concern in the community about the lack of real understanding, resources and concerns of other consequences to the community. She also thinks they should relay it is very difficult to understand.
Councilmember Iverson also suggested emphasizing the cost, noting that MOFD has a legal position and it is not a tax, but the cost of an unfunded mandate this imposes on people is scary and she thinks people should be provided with access to experts and guidance. It is not just respecting people’s ability to comply and to actually make people more compliant than less, but when there is a big unknown cost, people will be less compliant.
Councilmember Riley emphasized the user-friendly point and the template and the Vice Mayor’s point to provide people with an incentive to comply as opposed to reasons to run and hide and suggested keeping it broad.
Councilmember Iverson thanked the Mayor for spending the holiday weekend of mastering the subject.
Mayor Miller asked and confirmed that staff had direction. Mr. Biggs stated he would draft a letter and include the correspondence they received, thinks the Board should be able to access the recording of this meeting, and he asked and confirmed the Mayor will sign it.
H.2. Consider Appointing Additional Council Liaisons
Recommendation:
Receive Report, Discuss, and Provide Direction, if any, about Appointing Additional Council Liaisons including for CalShakes.
City Manager Biggs stated this was a Matter Initiated for the Council to consider the option of appointing additional Council Liaisons, including for CalShakes. Also attached in the staff report are other Liaison assignments, which have been to non-profits and other governmental agencies.

Mayor Miller stated she and Councilmember Riley met with Clive Worsley and learned there are grant opportunities. Councilmember Iverson had also mentioned at the time the Orinda Theater and the potential for a cultural liaison as well as other groups.
Councilmember Riley suggested the Village Starlight Players, as well.
Mayor Miller spoke about the cultural liaison role where it might include performance arts as well. Councilmember Iverson suggested it be limited to “iconic cultural institutions” to get started.
Mayor Miller opened the Public Forum.
Clive Worsley thanked Councilmembers for agendizing the item and he said he wanted to speak about how California Shakespeare Theater and the Bruns Amphitheater is continuing its transformation from being only a classical theater company into a multidisciplinary performing arts and cultural center with the CalShakes as its anchor. Going forward, rather than devoting their entire calendar just to pieces of classical theater they will produce one or two pieces of classical theater in a season and devote the rest of the calendar to other activities such as dance, comedy, live music, programming for families and youth audiences, civic events, corporate events and private events. He then spoke about his background with the theater and performing arts and their desire to improve their financial success and hope the City will join them in this success.
Councilmember Riley said the Council does not have the tradition of having a liaison for a for-profit business and have always done non-profits and she wondered about the Orinda Theater which is a for-profit business.
Councilmember Iverson said her thought was the analogy seemed very similar where they have had to branch out into live entertainment, comedy, music, a food and beverage program. They have to fundraise from the community to keep their sign lit up at times, and she thinks it is fine to start with CalShakes which she initially thought it felt very specific relative to the other list of committees.
Mayor Miller said each is located in different areas. When they began with talks about the downtown, they spoke about competition among restaurants which were struggling. She thinks it might be the same as CalShakes is further from the downtown. She recognized that Mr. Worsley has worked with other theaters, and noted critical mass is helpful.
Mr. Worsley agreed and commented that what is good for performing arts associations is good for the rest.
Mayor Miller said she believes she and Councilmember Kosla were liaisons to Friends of Orinda Creek because it was too much for one Councilmember. Similarly, here the City could have 2 liaisons that shared the task.
Councilmember Iverson suggested getting started with one liaison and an alternate.

Councilmember Riley said she thinks they want both theaters to thrive and survive and supported 2 liaisons.
Councilmember Iverson voiced support to start with CalShakes and the liaison could have the occasional conversation with the Orinda Theater as well.
Vice Mayor Gee voiced support, said she thinks it fits into the spectrum of evaluation of their economic redevelopment and attracting people. She agrees it is best to start something new simpler, and she made a motion to create a position to have a liaison to CalShakes and go from there.
Councilmember Riley agreed to volunteer to serve as Liaison.
MOTION by Vice Mayor Gee, and seconded by Councilmember Iverson, to create a position to have a Council Liaison for CalShakes and appoint Councilmember Riley. Said motion carried by unanimous (4-0) roll call vote.
H.3. City Council Meeting Schedule for 2024
Recommendation:
Review, Amend, and Adopt City Council Meeting Schedule for 2024 City Clerk Sheri Smith said at the last meeting there were 3 proposed changes. All dates were run by Councilmember Malkani. She can made 2 meetings in April and May but she cannot make the meeting on Monday, June 3rd. Therefore, staff would like direction before finalizing the calendar.
Councilmember Riley said another date could be May 28th instead of June 4th which is 1 week earlier but still 2 weeks apart. The second meeting for the budget would be June 18th. She would have to run this by Mr. Alessio.
Vice Mayor Gee asked if they would still have the meeting on May 21st, and Mayor Miller said they would have 3 May meetings and 1 June meeting.
Councilmember Riley said alternatively, they could hold 2 June meetings and switch them. She suggested adopting the changes Councilmember Malkani agreed to and then decide the June dates later.
Mayor Miller suggested continuing this item for the next meeting. City Manager Biggs stated Vice Mayor Gee will not be at the next meeting, and Vice Mayor Gee said she is fine with what is being proposed, and commented that not all 5 Councilmembers can always be at all meetings.
Mayor Miller asked and confirmed there was Council consensus for the dates scheduled for 2024.

I. COUNCILMEMBERS’ REPORTS – Councilmember Iverson reported she and Mayor Miller met with the Wilder 2x2 subcommittee and it was very well attended.
Most interesting was the discussion about the developer progress, the GHAD, the event that got a little bit out of control with lessons learned and measures taken, and they looked at some of the trails originally considered and the final trail map.
They will likely hold another subcommittee meeting in another 2 months so some of the concerns can be heard and addressed.
Mayor Miller reported today she attended a nice meeting with Assemblymember Rebecca Bauer-Kahan and Mayor and Councilmembers from other cities on ACA13 which is a Constitutional Amendment to require that any voter measure to change the threshold by which we pass local measures cannot be passed by a lesser threshold, such as changing the requirement for a 2/3 vote with a simple majority vote. Apparently, opponents are trying to make people that the ACA is a repeal of Prop 13, so she has asked Councilmembers to ensure their constituents understand the ACA has nothing to do with Prop 13.
Mayor Miller said they also heard from their Mosquito and Vector Control Manager.
There is an uptick in West Nile virus. They have needs for funding and she forwarded the information to the City Manager for a future meeting.
City Manager Biggs said many birds are testing positive with West Nile virus and precautions are asked to be taken by dump out any standing water outside, contact the District at contracostamosquito.com who can assist with eradication, recommends reducing the risk of mosquito bites and wear repellant, be active before mosquitos are out before and after sunset and sunrises, and report dead birds by calling 877-968-2473 or report it online at westnile.california.gov. He will also share this information through the City’s social media channels.
Councilmember Iverson noted there are interested people who had spoken regarding rats, and Mayor Miller stated the City Manager can discuss coming to an upcoming meeting.
J. CITY MANAGER’S REPORT – City Manager Biggs reported this weekend is the Classic Car Show and the Council had approved the Traffic Order for the event on Saturday. The event benefits the Orinda Association programs and there will be street closures downtown. Friday night the Orinda Rotary is holding the Dancing with the Cars event at the Community Center.
K. MATTERS INITIATED – Councilmember Riley said several residents have raised concerns since the Maui fire about the effective use of sirens. Recently, Berkeley installed 10 new sirens and they are planning on installing 5 more. She would like this to be a high priority and knows staff is working on this topic.
City Manager Biggs stated he has spoken with the Police Chief about this and they would invite the Director of the County’s Office of Emergency Services to come talk about the subject, and staff will circle back and look at scheduling this item.

AGENDA TITLE: Quarterly Report of Cash Disbursements for the Period April 1, 2023 through June 30, 2023 and Summary of Revenue, Expenditures, and Preliminary Fund Balances for July 1, 2022 through June 30, 2023
RECOMMENDATION:
Staff recommends that the City Council receive and file this report of cash disbursements, and preliminary fund balances for the period of April-June 2023.
BACKGROUND:
This report combines quarterly reporting to the City Council of two separate financial benchmarks: 1) The issuance of checks and payments for obligations incurred by the City during the quarter; 2) A report of Revenue and Expenditures for the quarter and preliminary fund balances based on year-to-date activity.
State Code References to City Financial Reporting
Section 37208 of the Government Code specifies the presentation of payments made by the City to the City Council. An option is available to forgo the presentation of these lists provided the City Council ratifies an audited Annual Comprehensive Financial Report (ACFR). The City practice has been to present a quarterly listing of payments, which goes above and beyond the minimum requirements in State law. Separate from the Payment Listing, California Government Code Section 41004 requires that the City Treasurer submit a quarterly report and accounting of all receipts, disbursements, and fund balances. This is contained in the second half of the report.
DISCUSSION:
Payment Listing
The disbursement listing includes detail for the months of April through June including A) Checks and electronic fund transfers (EFT) issued for accounts payable (Listed in ascending order of the check numbers); B) A summary of purchases made with Credit Cards (US Bank Corp); and C) A listing by name of payroll checks and direct deposits.
The total payroll costs are disclosed in the aggregate.
The payment and disbursement report includes detailed itemization of City issued payments as follows:

The General Accounts Payable payments totaled about $4.7 million. Approximately 63% of the general accounts payable were comprised of the following categories of expense: 1) County contract services for Police, Library and Animal Control totaling $1,083,961, 2) Capital Project costs ($1,061,907), this included payment of $536,688 for the annual pavement projects, 3) Debt service payment of $460,122 for the Civic Center Certificate of Participation, and 4) Replacement costs of $386,432 for two police vehicles and a street sweeper.
Included in the listing of General disbursements are payments to US Bank Corporation for expenses made with purchase cards. In addition to disclosing the total payment to the bank for credit card purchases, a separate summary list detailing the charges is provided (Attachment B). The purchases were made between February 16 to May 15, 2023 and the total expenditures made with credit cards was $56,773.
Report of Revenue / Expenditures and Fund Balances as of June 30, 2023 The following Table displays the activity for the fourth quarter (April through June 2023) in the first three columns. The right side of the table reports year to date results including the preliminary beginning and ending fund balance as of June 30, 2023.
Rather than listing all the funds individually the table combines funds by common groups.

The increase in General Fund, Library Fund, and Debt Service Fund balances reflected the semi-annual property tax revenue of $4.7 million received in April and June. Other significant revenue items included $2.2 million sales tax revenue, the receipt of a $1.4 million Property Tax In-Lieu of Vehicle License Fees payment disbursed by the County in May, and Park & Rec summer camp and rental revenue of $1.4 million.
The Stormwater Fund shows a negative balance as of June 2023, due to lag in the receipt of funds from the Contra Costa County Public Works program.
As noted in the Table above, the total fund balance across all funds as of June 30th has increased by approximately $3 million from the July 1, 2022 beginning balance of $37.1 million. The largest contributors for the increase are $2.2 million in Grants Fund for the receipt of American Rescue Plan (ARP) Federal Local Fiscal Recovery Fund in July 2022, $1.8 million in General Fund, and $1.3 million in Add-on Sales Tax Measure R, offset by a decrease of $2.2 million in Add-on Sales Tax Measure L for the Pavement projects and the Camino Sobrante Slide Project.

Agenda Item: F.4
Date: September 19, 2023
Department: City Council
AGENDA TITLE: Authorize Contract Amendment No. 3 with Schaaf & Wheeler Consulting Civil Engineers for On-call Civil Engineering Services for the San Pablo Creek Culvert Repair Project (#4187)
RECOMMENDATION:
Staff recommends that the City Council approve Contract Amendment No. 3 with Schaaf & Wheeler Consulting Civil Engineers to increase the contract value by $174,000 and extend the term of the agreement to June 30, 2026.
BACKGROUND:
The city currently has an on-call professional services contract with Schaaf & Wheeler Consulting Civil Engineers, who specialize in civil engineering hydraulics. The city assigned them a task in 2021 to determine repair options for the 1,300 lineal foot reinforced concrete box culvert which conveys San Pablo Creek in downtown Orinda, from the Safeway Parking lot to Orinda Way. The city is the owner of this culvert, which is within accepted drainage easements which traverse the private properties.
Schaaf & Wheeler performed field inspections and provided a report of their findings and recommendations, and provided a proposal to perform design work for the repairs.
The contemplated repair work was to reline the culvert invert (floor), where abrasion has led to exposed rebar. Their preliminary engineering was authorized in contract Amendment 2, which was executed in January 2022 and increased the value of the contract from $60,000 to $348,000. The scope of work included material sampling/testing, hydraulic analysis, completing plans and specifications, and applying for regulatory permits. The scope also included investigations and survey/monitoring an out of plumb west wall in an open-channel section of the culvert. Based on the findings of that work, they evaluated repair options for the leaning wall and have provided a report with recommendations (Attachment A, Memorandum dated August 18, 2023).
Regulatory permits were recently obtained and the current project schedule is to advertise for bids in late 2023 to perform construction work in summer 2024. The repair work may take two or more construction seasons to complete, since the work will be limited to the low flow summer months and as required by the regulatory permits from May 1 to October 31. However, construction may be further restricted if any nesting birds are found in the area or if there are significant flows in the culvert.
DISCUSSION:
Schaaf & Wheeler’s proposal for design work addressing the leaning culvert wall, and other necessary services, is shown in Attachment B. (The other services are bid and F.4
Packet Pg. 53
construction/environmental support services during construction, which were not included in prior tasks or proposals). The estimated value of work is $145,000. Staff recommends approving Amendment #3 (Attachment C), which would increase the contract value by $174,000 (the estimated $145,000 plus a 20% contingency) to a new not-to-exceed contract value of $522,000. The work will be invoiced on a time and materials, actual cost basis, as is typical for Orinda’s on-call professional services contracts. Since this work will extend beyond the expiration date of the current contract (June 30, 2024), the amendment also extends the term to June 30, 2026.
Overall Project Cost Estimates
To date, approximately $250,000 has been expended with Schaaf & Wheeler for their work. A summary of overall project costs, including the cost of the subject Amendment #3 and the leaning wall repair, is shown in Attachment D. The overall estimated cost of the project is $4,334,000. The latest CIP for the San Pablo Creek Culvert Project No. 4187 has a total budget of $4,200,000. As the project progresses, cost forecasts will be updated and when construction bids are received, Staff will compare costs to the budget and determine if funding changes/appropriations are necessary.
NEXT STEPS:
Upon City Council authorization, Contract Amendment No. 3 will be executed by the parties, subject to review by the City Attorney.
FISCAL IMPACT:
There is adequate funding in the current project budget to accommodate the subject Amendment.

MEMORANDUM
DATE: August 18, 2023
TO: T. Ryan O’Kane, PE, City of Orinda
FROM: Ben Shick, PE
SUBJECT: San Pablo Creek Culvert, Leaning Wall Evaluation Introduction
The City of Orinda contracted Schaaf & Wheeler to evaluate and provide recommendations for repairing of the San Pablo Creek culvert that is located on the northeast side of Camino Pablo and runs from approximately 31 Orinda Way to the outfall near 104 Camino Pablo. During field investigations it was noted that the concrete walls on the open channel section of the culvert, just downstream of Avenida de Orinda are leaning inward and significant cracking along the walls and invert were observed (see photos included as an attachment to this memorandum).
Additionally, there is pavement cracking and subsidence along the adjacent roadway, Camino Pablo. The location of the leaning walls is shown in Figure 1.
Figure 1. Location of Leaning Walls
Subsequently Schaaf & Wheeler was tasked with further investigating the leaning walls and developing recommendations for supporting and repairing the walls. Investigations include topographic surveying of the leaning wall to monitor the movement, geotechnical investigations and laboratory testing, material sampling and testing, and structural analysis. This memorandum summarizes the evaluation and provides recommendations for supporting and repairing the walls.

Field Investigations & Evaluation
Schaaf & Wheeler and structural engineering subconsultant, Peoples Associates Structural Engineers (PASE), formerly Finn Design Group, conducted field investigations to evaluate the existing conditions of the leaning walls. A summary of the observations and evaluation is included herein.
The existing open portion of San Pablo Creek consists of a U-shaped concrete channel with a concrete invert and a concrete wall on each side. The channel is approximately 20 feet wide with 10-foot-tall walls. Record drawings for the channel are not available; however, BSK Associates has performed materials forensic services to determine the following:
1. The walls are approximately 10-inches thick with two layers of reinforcing steel. The vertical reinforcement is approximately 8-inches on center, and the horizontal reinforcement is approximately 18-inches on center.
2. The middle portion of the invert is approximately 9-inches thick with two layers of reinforcement in each direction at approximately 18-inches on center. Near the walls, the invert increases to approximately 12-inches thick.
3. Samples of the concrete were tested for compressive strength and found to have minimum f’c = 4,000 psi. Samples of the reinforcing steel were tested and found to be consistent with ASTM A615 Grade 40 steel (fy = 40,000 psi).
The existing walls are divided into approximately 15-foot-long panels and are leaning inward into the channel. The amount of lean varies along the length of the channel and is worse on the west side. The west walls lean a maximum of about 11¼”, and the west walls lean a maximum of about 5”. There is also damage to the channel invert in front of the walls which is again worse on the west side. The damage consists of a crack in the invert about 24 inches in front of the walls and running parallel to the walls. At the west side, the crack is up to 2¼” deep and includes loss of material.
The exact cause of the distress and damage is unknown but could be due to any or all of the following:
1. Actual loads on the walls and invert may exceed what they were originally designed for.
2. The presence of expansive soils behind the walls.
3. The drainage system behind the walls may not be functioning properly.
4. Surcharge loads on both sides from large trees.
5. Increased loads on the west side due to the nearly 1:1 backslope and possible surcharge loads from the adjacent Camino Pablo roadway. This is likely why the distress and damage to the west side is worse than the east side.
The cracking and damage to the invert is possibly due to 1) the invert not being thick enough, 2) the invert not being reinforced well enough, and/or 3) there not being enough of a heel on the invert behind the walls. It is possible that the cracking is occurring where the invert thickness F.4.a

transitions from 12-inches thick to 9-inches thick. The invert cracking has allowed rotation of the walls and, hence, the leaning of the top of the walls.
Geotechnical Investigations
Geotechnical investigations were conducted by Schaaf & Wheeler’s subconsultant, BSK Associates, to classify the subsurface conditions adjacent to the leaning wall locations. Soil borings were performed along Camino Pablo immediately upslope of the west culvert wall and within a private property adjacent to the east culvert wall. The conclusions and recommendations are presented in the geotechnical report which is included as an attachment to this memorandum.
Materials Forensics Services
Materials Forensics Services were conducted by Schaaf & Wheeler’s subconsultant, BSK Associates, to determine concrete thicknesses, concrete compressive strength, and rebar reinforcement of the walls and invert. The results are summarized in a letter which is included as an attachment to this memorandum.
Survey Point Monitoring
Survey monitoring points were established and surveyed by Schaaf & Wheeler’s subconsultant, Kier & Wright, to determine the movement of the walls over time. The survey points were established on 2/17/2022 and were monitored for movement on 3/21/23. Both sides of the leaning walls were recorded to move 0.02 feet (1/4-inch) inward during the monitoring period.
The movement is not significant for one year of monitoring; however, over time it would result in significant defects and potential failure of the walls. The walls are slowly rotating and leaning further into the channel.
Survey monitoring points were also established on the eastern edge of pavement on Camino Pablo, adjacent to the leaning walls. The monitoring points were recorded to move between
0.01 and 0.02 feet towards the culvert. Again, this movement is not significant for one year of monitoring; however, over time it may cause significant issues to the roadway and culvert.
The survey monitoring points and results are included as an attachment to this memorandum.
Wall Repair Alternatives
Schaaf & Wheeler’s structural engineering subconsultant, PASE, evaluated several different wall repair concepts as listed below:
1. Installation of steel beams transverse across (perpendicular to) the channel. The beams would act as struts between the walls and prevent further movement of the top of the walls into the channel. This concept that has been chosen as the preferred alternative as described in the following section.
2. Installation of soil nails through the walls into the existing backfill behind the walls. The soil nails would consist of a steel tendon inserted into a hole drilled at an angle of 10 – 20 degrees below a horizontal plane and filled with concrete grout, bonding them to the surrounding soil. The tendons would be anchored to the face of the walls, holding the F.4.a

wall back from further movement. Two rows of soil nails, each at about 5 feet on center horizontally, would be installed on each side of the channel. Soil nails were initially identified as a likely preferred alternative; however, some potential problems were identified including 1) right of way issues with installation into the open parcel on the east side and 2) possible difficult drilling conditions due to roots from the numerous trees behind the walls (including the large redwood trees on the east side).
3. Construction of continuous concrete “fillets” or buttresses inside the channel along both walls. The fillets would strengthen the wall to invert connection as well as the walls themselves. However, the fillets would reduce the cross-sectional area of the channel which, from a hydraulic perspective, was deemed to be unacceptable.
4. Combination of a top row of soil nails with a lower continuous concrete fillet.
5. Discretely spaced concrete buttress columns founded on CIDH concrete piers installed through and into the soil below the invert. The leaning tops of the walls, though, would require the piers to be drilled away from the face of walls, and the columns would extend significantly into the channel. Though they would be discretely spaced elements, this would again affect the hydraulic capacity and flow in the channel.
Recommended Wall Repairs
Steel beams installed across the channel have been identified as the preferred alternative. The beams will be installed at approximately 7.5 feet on center, two per wall panel, for a total of 10 beams. Although the beams will create new shading in the channel, it will fit within the current environmental permits for the proposed project. A continuous reinforced concrete beam element will also be required along the top of the walls in order for the existing concrete walls to be able to span vertically and horizontally between the invert and the new beams. A conceptual wall repair detail is included as an attachment to this memorandum. The new concrete beams will be doweled to the top of the existing walls, and the steel beams will be bolted in place with field-drilled holes to provide field adjustability. Repairs to the channel invert will also be performed as part of the larger channel rehabilitation project.
Hydraulic Evaluation of Proposed Repairs
The preferred repair alternative includes a 1’ x 1’ concrete beam that will extend below the top of the channel wall. Schaaf & Wheeler evaluated the hydraulic conditions of the culvert at the proposed repair location and determined that the hydraulic grade line of the 100-year flow rate is below the limits of the proposed concrete repairs. Therefore, the proposed repairs will not have a hydraulic impact on the culvert.
Conclusion
Based on the assessment and analysis discussed herein, it is recommended to repair the leaning walls of the San Pablo Creek Culvert in the near future. The repairs will include 10 steel beams spanning across the culvert and a continuous reinforced concrete beam along the top of the walls.
The estimate of probable construction cost for the proposed repairs is included in Table 1 below.

1. INTRODUCTION
This report presents the results of our geotechnical investigation to evaluate a portion of the San Pablo Creek culvert along the eastern side of Camino Pablo, just north of Camino Sobrante, from south of the Safeway shopping center to just north of Avenida De Orinda in Orinda, California. A Vicinity Map showing the location of the project site (Site) is presented on Figure 1. Thisreport contains a description of our site investigation methods and findings, including field and laboratory data. It also provides conclusions and recommendations, which may only be used for this project.
1.1 Project Understanding
As shown on the Site Plan, Figure 2, the pertinent segment of the San Pablo Creek culvert being evaluated for this investigation (i.e., Site) consists of an open concrete culvert extending for about 100 linear feet in length. The portions of the San Pablo Creek culvert extending to the north and south of the Site are covered (i.e., consist of box culverts). During a recent routine inspection of the culvert by Schaaf & Wheeler, they noticed that some of the wall panels in the open segment of the culvert are leaning into the culvert. They also noticed that the reinforcing steel has been exposed and corroded for portions of the concrete slab at the bottom of the culvert. In other areas, water was observed seeping between the concrete slab joints and through the weep holes located near the bottom of the culvert walls. We understand that there are no as-built plans or previous geotechnical data/report available for this segment of the culvert.
If the actual project understanding differs significantly from that described above, we should be notified so that we can review our scope of services for applicability.
1.2 Purpose and Scope of Services
The purpose of this investigation was to explore and evaluate the subsurface conditions along the sides of the open segment of the concrete culvert to provide geotechnical input to remediate the distress. The scope of services, as outlined in our February 4, 2022, proposal (Proposal No. GL21-22953), consisted of pre-field activities, a subsurface investigation, laboratory testing, engineering analysis, and preparation of this report. BSK’s scope also includes provision of materials forensics services for this project, but these services are not covered by this report. This investigation specifically excludes the assessment of site environmental characteristics, particularly those involving hazardous substances.

2. SITE INVESTIGATION
2.1 Subsurface Investigation
A subsurface investigation was performed on March 21 and 22, 2022 to evaluate the subsurface conditions along the eastern and western sides of the creek culvert. As outlined in our proposal, the subsurface investigation consisted of drilling three (3) soil borings at the approximate locations shown on Figure 2 (labeled borings B-1 through B-3). The soil borings were performed by using a truck-mounted rig equipped with solid stem augers These borings extended to depths of approximately 5 to 22½ feet below the existing ground surface (BGS). The borings were logged by a BSK geologist and soil samples were obtained from the borings at selected intervals. Taber Drilling of West Sacramento, California was subcontracted to provide drilling services.
Prior to the start of our subsurface exploration, Underground Service Alert (USA North 811) was contacted to provide utility clearance. A private utility locator was also subcontracted to clear the exploration location at 20 Avenida De Orinda. Drilling permits were obtained from the Contra Costa County Environmental Health Division (County). Upon completion of the subsurface investigation, the borings were backfilled with cement grout under the supervision of County inspector and capped with Rapid Set® concrete mix in paved areas. Excess cuttings generated during drilling were spread near the exploration locations.
The locations of the borings were estimated by our field geologist based on approximate GPS coordinates collected from a phone-based application and rough measurements from existing features at the Site.
Elevations shown on the boring logs were estimated using Google Earth Professional. As such, the elevations and locations of the borings should be considered approximate to the degree implied by the methods used.
Relatively undisturbed samples of the subsurface materials were obtained using a split spoon sampler with a 2.5-inch inside diameter (I.D.) and a 3-inch outside diameter (O.D.) fitted with stainless steel liners.
In addition, disturbed samples were obtained with a Standard Penetration Test (SPT) split spoon sampler with a 1.4-inch I.D., without stainless steel liners. The samplers were driven 18 inches using a 140-pound, automatic trip hammer falling 30 inches, and blow counts for successive 6-inch penetration intervals were recorded. The blow counts corresponding to each 6-inch interval were reported on the final boring logs.
Disturbed bulk samples of near-surface soils were also collected from the auger cuttings at some of the borings.
After the samplers were withdrawn from the boreholes, the lined samples were removed, sealed to reduce moisture loss, labeled, and returned to our laboratory. Prior to sealing the samples, strength characteristics of the cohesive soil samples recovered were evaluated using a hand-held pocket penetrometer. The results of these tests are shown adjacent to the samples on the boring logs.

Soil classifications made in the field from the borings were re-evaluated in the laboratory after further examination and testing. The soils and bedrock were classified in the field in general accordance with the Unified Soil Classification System (Visual/Manual Procedure - ASTM D2488) presented on Figure A-1 and the Rock Description Criteria shown on Figure A-4 in Appendix A. Where laboratory tests were performed, the designations reflect the laboratory test results in general accordance with ASTM D2487 as presented on Figure A-1. A Soil Description Key is presented on Figure A-2 and a key to the symbols used in the boring logs is presented on the Log Key, Figure A-3. Sample classifications, blow counts recorded during sampling, and other related information were recorded on the boring logs. Logs of our borings are also presented in Appendix A. A discussion of the subsurface conditions encountered at the Site is presented in the “Subsurface Conditions” section of this report.
2.2 Laboratory Testing
Laboratory tests were performed on selected soil samples to evaluate their physical characteristics and engineering properties. The laboratory testing program included dry density and moisture content, Atterberg limits, unconsolidated-undrained triaxial compression (TXUU), and sieve analysis. Most of the laboratory test results are presented on the individual boring logs. The results of the Atterberg limits, TXUU, and sieve analysis are also presented graphically in Appendix B.
Analytical testing was performed as part of our investigation on soil samples obtained from borings B-1 and B-3 at depths of approximately 13½ and 11 feet BGS, respectively, to assist in evaluating the corrosion potential of the site soils and bedrock. The corrosivity testing and evaluation was performed by CERCO Analytical, State-certified laboratory in Concord, California for pH, resistivity, chloride content, and sulfate content in accordance with Caltrans test methods. The results of the corrosion testing are discussed in the “Corrosion” section of this report and presented at the end of Appendix B.

3. SITE GEOLOGY AND SEISMICITY
The Site is located within the central, southern portion of the Briones Valley Quadrangle, which is in the central portion of the Coast Ranges Geomorphic Province of California. The Coast Ranges is a region dominated by northwest trending ridges and valleys that generally parallel the San Andreas Fault and other actives faults. Within the East Bay Hills, the Coast Ranges consist primarily of a thick sequence of Tertiary sedimentary and volcanic rocks that overlie older Mesozoic rocks. The Tertiary rocks are generally tightly folded along northerly to northwesterly fold axes. Low lying areas are generally filled with Holocene to Pleistocene alluvial and fluvial deposits.
Several geologic maps prepared by the California Geological Survey (CGS) and the United States Geological Survey (USGS) cover the Orinda area. According to the USGS (20001), the Site is mapped as late Miocene sedimentary and volcanic rocks (map symbol Tus) that includes conglomerate, sandstone, and siltstone with interbedded basalt and limestone as shown on the Area Geology Map, Figure 3. This unit is similar to the late Miocene Orinda Formation – distinctly to indistinctly bedded, nonmarine, pebble to boulder conglomerate, conglomeratic sandstone, coarse- to medium-grained lithic sandstone, and green to red siltstone and mudstone.
Several periods of tectonic deformation have occurred during Mesozoic and Cenozoic time which has led to the production of numerous faults, both active and non-active. Currently, active faulting in the San Francisco Bay Area occurs most frequently along faults associated with the San Andreas fault system, including Hayward and Calaveras faults. Seismicity in the Orinda area is related to the active Hayward and San Andreas Faults. The Hayward is located approximately 3 miles southwest of the Site and the San Andreas is about 21 miles to the southwest. The Moraga Fault is located approximately 600 feet southwest of the Site but is not considered active by the CGS. The Site is not located within an Alquist-Priolo Earthquake Fault Zone, and no active faults are known to cross or project towards the Site.
3.1 Geologic and Seismic Hazards
3.1.1 Fault-Related Ground Surface Rupture and Ground Shaking The Site is not situated within a State-designated Alquist-Priolo Earthquake Fault Zone where site-specific studies addressing the potential for surface rupture are required and no known active faults traverse the Site. Therefore, the potential for fault-related ground surface rupture at the Site is considered low.
However, active faults in the region surrounding the Site are capable of producing significant ground shaking at the Site.

In 2015, scientists and engineers released a new earthquake forecast for the State of California2. It updates the earthquake forecast made for the greater San Francisco Bay Area by the 2007 Working Group for California Earthquake Probabilities. According to this recent study, there is a 72 percent probability that one or more magnitude M6.7 or greater earthquakes will occur in the San Francisco Bay Area between 2014 to 2044.
Based on the above information, we conclude that Site will likely be subjected to moderate to intense ground shaking from a significant earthquake on the aforementioned faults or other active faults in the San Francisco Bay Area in the future.
3.1.2 Expansive Soils
According to our Atterberg limits test results for our investigation, the site soils in the upper approximately 15 feet BGS have a moderate to high expansion potential when subjected to changes in moisture content.
Soils with a high expansion potential exert higher earth pressures on retaining walls than soils with lower expansion potential.
3.1.3 Liquefaction Potential
Liquefaction is a condition where saturated, granular soils undergo a substantial loss of strength and deformation due to pore pressure increase, resulting from cyclic stress application induced by earthquakes. In the process, the soil acquires mobility sufficient to permit both horizontal and vertical movements if the soil is not confined. Soils most susceptible to liquefaction are loose, clean, uniformly graded, silt and fine sand, as well as some lean clay deposits.
In order for liquefaction triggering to occur due to ground shaking, it is generally accepted that four conditions will exist:
• The subsurface soils are in a relatively loose state
• The soils are saturated
• The soils have low plasticity
• Ground shaking is of sufficient intensity to act as a triggering mechanism In addition, after soil liquefies, dissipation of the excess pore pressures can produce volume changes within the liquefied soil layer, which can result in ground surface settlement.
The Site is located with the Briones Valley quadrangle, which has not been mapped by the California Geological Survey for liquefaction hazard zones. Based on the composition, consistency, and relative 2 Field, E.H., and 2014 Working Group on California Earthquake Probabilities (2015), UCERF3: A new earthquake forecast for California’s complex fault system: U.S. Geological Survey 2015–3009, 6 p., https://dx.doi.org/10.3133/fs20153009.

Orinda, California Page 6
density of the soils, the depth to bedrock, and lack of free groundwater in our borings, we conclude that the potential for liquefaction to occur at the Site during a significant seismic event is low.
3.1.4 Lateral Spread Potential
Lateral spread is a potential hazard commonly associated with liquefaction where extensional ground cracking and settlement occur as a response to lateral migration of subsurface liquefiable material. These phenomena typically occur adjacent to free faces such as slopes and creek channels. Because the potential for liquefaction to occur at the Site is deemed to be low, we conclude that the potential for lateral spread to occur at the Site as a result of a future seismic event is low.
3.1.5 Dynamic Compaction/Seismic Settlement Potential
Another type of seismically induced ground failure, which can occur as a result of seismic shaking, is dynamic compaction or seismic settlement. Such phenomena typically occur in unsaturated, loose granular material or uncompacted fill soils. Based on the consistency/density of the soils and the depth to bedrock encountered in our borings, we conclude that the potential for seismic settlement to occur immediately behind the culvert walls or below the base of the culvert is low.
3.1.5 Slope Stability
Although no readily visible signs of deep-seated slope instability were observed within the slope located immediately west of the open culvert, it is possible that this slope could experience some instability during a future significant seismic event in one of the active faults in the region surrounding the Site. Further discussion about this potential is discussed in the “Conclusions” section of this report.

4. SURFACE CONDITIONS
According to preliminary drawings for the project, the open culvert is approximately 20 feet wide at the base. The ground surface elevation is relatively flat on the east side of the open culvert except for the southern part where a concrete ramp is located and where the ground slopes up to match grade at Avenida de Orinda. A large redwood tree is located immediately behind the southern portion of the east side of the open culvert. The ground surface slopes upwards on the west side of the open culvert until it meets the east shoulder of Camino Pablo. According to Google Earth Pro, ground surface elevations range from about 405 to 410 feet behind the east side of the open culvert and about 420 to 425 feet immediately behind the outboard edge of the shoulder of the northbound lane of Camino Pablo. The slope gradient immediately behind the west side of the open culvert is unknown at this time but is believed to be somewhere between a 1H:1V to 3H:1V (horizontal to vertical). The slope is covered with trees and bushes.
We visited the Site with a representative from the Finn Design Group (the structural engineer for the project) on February 18, 2022. Based on our observations and approximate measurements made at the Site on that day, the open culvert wall panels are about 10 feet high and appear to be about 9½ inches thick based on measurements made through the weepholes. Two of the wall panels at both sides of the open culvert have a horizontal offset relative to each other of about 3 inches at the top. The top of the wall panels at the west side of the open culvert are leaning about 10 to 11¼ inches towards the culvert, while wall panels at the east side of the open culvert are leaning about 2 to 5 inches towards the culvert based on measurements made using a plumb bob and measuring tape. There was no water flowing through the weepholes for the open culvert wall on the west side, but there was water flowing through the weepholes for open culvert wall on the east side. Water approximately 0 to 2 inches deep was flowing through the open culvert except for an approximately 1-foot-wide zone adjacent to the west culvert wall, which was dry.

5. SUBSURFACE CONDITIONS
According to our soil borings, the Site is underlain by fill, native alluvial soils, and bedrock as follows:
• Fill consisting of medium dense clayey sand with gravel and containing bedrock fragments was encountered within boring B-1 in the upper approximately 8 feet BGS. The fill was underlain by firm to hard lean clay and dense clayey gravel. Moderately weathered claystone was encountered at about 21½ feet BGS.
• Boring B-2 encountered approximately 5 feet of loose silty sand fill. An unmarked pressurized sanitary sewer line was encountered at a depth of 5 feet BGS. The boring was immediately terminated and we notified Schaaf Wheeler, the City of Orinda, the Central Contra Costa Sanitary District (CCCSD), and 911. A CCCSD crew then arrived at the Site to repair the sewer line. • Boring B-3 encountered approximately 11 feet of fill consisting of interbedded layers of loose to medium dense poorly graded gravel and clayey gravel and firm sandy silt. Beneath the fill, moderately to highly weathered bedrock consisting of shale was encountered.
Free groundwater was only observed within boring B-3 at approximately 8½ feet BGS. However, it is possible that the groundwater observed in boring B-3 is perched above the soil/bedrock contact line and its source is the adjacent culvert. Groundwater was not observed in the remaining borings. According to the State Water Resources Control Board GeoTracker website, groundwater data from the mid-2010s indicate levels ranging from about 5 to 15 feet BGS near the Site area.
The above is a general description of soil, bedrock, and groundwater conditions encountered at the Site.
For a more detailed description of the soils encountered, refer to the boring logs in Appendix A.
It should be noted that subsurface conditions can deviate from those conditions encountered at the boring locations. If significant variation in the subsurface conditions is encountered during construction, it may be necessary for BSK to review the recommendations presented herein and recommend adjustments as necessary.

6. CONCLUSIONS
As previously discussed, the top of the walls for the open culvert are leaning approximately 2 to 11¼ inches towards the culvert. Without having the original design plans for the open culvert, it is difficult for us to pinpoint the exact cause(s) of this movement. However, possible causes could include the presence of expansive soils behind the walls in combination with under-designed walls, saturation of the backfill behind the walls in combination with poor drainage behind the walls, and surcharge loads imposed by large trees near the open culvert walls and by the sloping surface on the west side of the open culvert.
Based on our previous discussions with Schaaf & Wheeler and the Finn Design Group and review of conceptual remediation drawings, possible repair options to stop further movement of the open culvert walls could consist of:
1. The installation of concrete cross braces connecting the top of the walls,
2. Installation of soil nails through the walls, and
3. The installation of buttress columns in front of the walls.
If used, the buttress columns will be supported by cast-in-drilled hole (CIDH) piers. Although not considered as part the conceptual remedial drawings, tiebacks could be used in lieu of soil nails if deemed appropriate by the design team. Therefore, we included recommendations for tiebacks in the “Recommendations” section of this report. In addition, consideration should be given to adding a 3- to 5- foot-tall screen wall above the west wall of the open culvert in case the slope immediately west of the culvert experiences instability during a future significant seismic event in one of the active faults the region surrounding the Site.
Based on the results of our subsurface investigation and our experience, it is our opinion that the proposed repair options are feasible. This conclusion is based on the assumption that the recommendations presented in this report will be incorporated in the design and construction of this project. Recommendations regarding geotechnical design and construction aspects for the project are presented in the “Recommendations” section of this report.

7. RECOMMENDATIONS
Presented below are recommendations for lateral earth pressures, seismic wall pressures, 2019 CBC seismic design parameters, CIDH piers, soil nails, tiebacks, and earthwork as well as associated construction considerations for this project.
7.1 Lateral Earth Pressures
The lateral earth pressures recommended for use in the design of the wall repair are presented in the table below and are expressed as equivalent fluid pressures (unit weights) in units of pcf. We provided both drained and undrained earth pressures. Undrained lateral earth pressures should be used for the wall repair unless as-built plans are located for the existing open culvert walls that show a robust drainage system behind the walls. Because free groundwater was observed at a depth of approximately 8½ feet BGS at boring B-3, we recommend using a design groundwater depth of 5 feet BGS behind the walls. A triangular lateral earth pressure distribution should be used.

Orinda, California Page 11
7.2 Seismic Wall Pressures
According to Section 1803.5.12 of the 2019 California Building Code (CBC), dynamic seismic lateral earth pressures need to be included in the design of foundation walls and retaining walls supporting more than 6 feet of backfill height. Based on Agusti and Sitar (2013)3 and a PGAM value of 1.009g (refer to table in the “2019 CBC Mapped Seismic Design Parameters” section of this report), we recommend using a seismic increment pressure of 43 pcf for flexible walls and a seismic increment of 74 pcf for restrained walls. The seismic increment pressure should be applied as a triangular distribution with the resultant force acting 1/3 times the wall height above the base of the wall.
7.3 Surcharge Loads
For surcharge loads imposed on culvert walls, a rectangular distribution with a uniform pressure equal to one-third of the surcharge pressure should be used for unrestrained walls (active earth pressure condition) and one-half of the surcharge pressure for restrained walls (at-rest earth pressure condition).
Surcharge loads caused by vehicular and/or construction traffic adjacent to the wall may be assumed to consist of a rectangular distributed uniform pressure of 100 psf acting from the ground surface to a depth of 10 feet BGS. Additional analyses during design may be needed to evaluate the effects of non-uniform surcharge loads such as point loads, line loads, or other such presently undefined surcharge loads. In that case, we should be consulted for supplemental geotechnical recommendations.
7.4 Screen Wall
As discussed in the “Conclusions” section of this report, consideration should be given to installing a 3- to 5-foot-tall screen wall above the west wall of the open culvert in case the slope immediately west of the culvert experiences seismic instability in the future. If this screen wall is incorporated into the wall repair, it should be designed to temporarily resist the lateral earth pressures presented in the “Lateral Earth Pressures” section of this report. We recommend reducing the earth pressures by about one-third to account for their temporary nature as we anticipate the slope to the west of the screen wall would need to be reconstructed relatively quickly in order to reestablish the shoulder of Camino Ramon. Likewise, we do not believe it would be appropriate to design this screen wall to resist seismic wall pressures because of the temporary nature of soil that could be accumulated behind it after a significant seismic event.
Also, if this screen wall is included above the west wall of the open culvert, the added lateral earth pressures imposed by the screen wall should be considered in the evaluation of the existing culvert wall. 3 Agusti, G.C. and Sitar, N.(2013), Seismic Earth Pressures on Retaining Structures in Cohesive Soils, Geotechnical Engineering Department of Civil and Environmental Engineering, University of California at Berkley, Report No.

7.5 2019 CBC Mapped Seismic Design Parameters
The seismicity of the region surrounding the Site is discussed in the “Site Geology and Seismicity” section of this report. From that discussion, it is important to note that the Site is in a region of high seismic activity and will likely be subjected to moderate to intense ground shaking during the life of the project.
Therefore, the wall repairshould be designed in accordance with applicable seismic provisions of the 2019 California Building Code (CBC) and the seismic parameters presented in the table below. 2019 MAPPED CBC SEISMIC DESIGN PARAMETERS

7.6 CIDH Piers
If used, the buttress columns will be supported by cast-in-drilled hole (CIDH) piers, which would derive their load capacity from skin friction between the concrete and the surrounding soil. An allowable skin friction of 500 pounds per square foot (psf) may be used to resist downward loads. Resistance to upward loads, if applicable, may be calculated using 2/3 of the allowable skin friction plus the weight of the piers.
These allowable values include a factor of safety of at least two and may be increased by one-third for supporting total loads, including wind and seismic loads. Piers should have a minimum diameter of 18 F.4.a

inches and be a minimum of 15 feet deep below lowest adjacent grade. Piers should not be spaced less than 3 diameters apart (center to center) or reduction to axial capacity would apply. Settlement of CIDH piers is expected to be negligible.
Resistance to lateral loads for CIDH piers can be provided by passive resistance against the face of the piers using an allowable equivalent fluid pressure of 350 pounds per cubic foot (pcf) up to a maximum of 3,000 psf acting against the piers. The passive resistance may be applied to a width of twice the diameter of the piers. The passive pressure value includes a factor of safety of about 1½.
We recommend that drilled pier steel reinforcement and concrete be placed within about 4 to 6 hours upon completion of each drilled hole. As a minimum, the holes should be poured the same day they are drilled. If the holes cannot be backfilled the same day they are drilled, the hole needs to be checked for caving, sloughing or squeezing prior to setting the rebar cage and checked again before pouring concrete.
The steel reinforcement should be centered in the drilled hole. Concrete used for pier construction should be discharged vertically into the holes to reduce aggregate segregation. Under no circumstances should concrete be allowed to free-fall against either the steel reinforcement or the sides of the excavation during construction.
If water more than 6 inches deep is present during concrete placement, either the water needs to be pumped out or the concrete needs to be placed into the hole using tremie methods. If tremie methods are used, the end of the tremie pipe must remain below the surface of the in-place concrete at all times.
Unit prices for dewatering and/or tremie placement methods should be obtained during the bidding process.
Concrete for drilled piers should be designed and placed in general conformance with the recommendations provided in ACI 336.3R-14, Design and Construction of Drilled Piers . The recommendations provided within ACI 336.3R-14 should be followed, especially when concrete placement is necessary below groundwater level, in caving or sloughing soils, or in sand, which may necessitate casing or the slurry displacement method for concrete placement. These methods require concrete placement at higher slumps than “dry” conditions and concrete mix specifications, including the addition of concrete admixtures and consideration of consolidation methods, should be provided by the design team. If temporary casing is used, it should consist of smooth walled steel. Corrugated metal pipe (CMP) should not be used as temporary casing because it has a tendency to create voids or disturbed zones during removal.
7.7 Soil Nails
Typically, soil nails are comprised of a steel tendon that is inserted into a hole drilled at an angle of between 10 to 20 degrees below a horizontal plane into the cut face and subsequently filled with concrete grout. The entire length of soil nails is considered bonded to the surrounding soil/bedrock.

7.8 Tiebacks
Typically, tiebacks are comprised of steel tendons that are inserted into holes drilled at angles of between 15 to 30 degrees below a horizontal plane into the soil or backfill to be retained and subsequently filled with concrete grout. Only a portion of the total length (referred to as the bonded length) of the tieback tendons is bonded to the surrounding soil. Corrosion protection for the tiebacks and other corrosion sensitive components of the wall should be included in the wall design. The corrosivity test results we performed are summarized in the “Corrosion” section of this report and are presented at the end of Appendix B.
Based on our interpretation of the subsurface data obtained from our borings, associated laboratory test results, and FHWA (1999)5, we recommend that the tieback design parameters shown in the table below be used for design of the tiebacks.

7.9 Other Aspects of Soil Nails and Tiebacks
7.9.1 Design and Testing
The preliminary ultimate bond stress/strength values indicated above for soil nails and tiebacks were derived based on experience with similar subsurface conditions and typical values provided in FHWA (1999, 2015). These preliminary design values should be confirmed and validated during construction via testing as recommended below.
The wall designer will be responsible for designing the actual soil nails/tiebacks and their horizontal/vertical layout/spacing, design of the soil nail/tieback protective facing, and developing acceptance criteria for verification, proof, and creep testing (for soil nails) and proof, creep, and performance testing (for tiebacks) during construction. The layout/spacing of the soil nails/tiebacks should be modified as needed during construction based on the testing, such as adding more soil nails/tiebacks, decreasing the spacing between soil nails, adding more rows of tiebacks, etc.
For soil nail walls, at least 2 verification tests should be performed for each soil/bedrock unit and at least 5 percent of the production soil nails should be proof tested. All soil nails that undergo verification and proof testing should be creep tested.
For tiebacks, performance testing should be performed on at least the first two tiebacks installed for each soil/bedrock unit and on a minimum of 2 percent of the remaining production tiebacks thereafter. The remaining tiebacks that are not performance tested should be proof tested. All tiebacks should be creep tested.
Prior to the start of construction, the geotechnical aspects of the design calculations, plans, and specifications for these soil nails/tiebacks should be reviewed by BSK.

Orinda, California Page 16
7.9.2 Construction
The contractor selected to install soil nails or tiebacks should provide proof of at least 5 years of continuous experience designing and constructing these types of soil nails/tiebacks under similar subsurface conditions and accessibility constraints as those found at the project site.
A BSK representative should be present at the Site on a full-time basis during drilling, installation, and testing of soil nails/tiebacks.
7.10 Earthwork
We expect earthwork activities for this project to be limited to the excavation of CIDH Piers (if applicable) and possibly placement of fill and backfill for excavations. Earthwork activities should be observed by a representative from BSK. If subsurface conditions vary from those described in this report, a representative from BSK should observe and evaluate the competency of existing soils and bedrock. In general, soft/loose or unsuitable materials encountered should be overexcavated, removed, and replaced with compacted engineered fill material under the observation of a representative from BSK.
Site preparation and grading for this project should be performed in accordance with the site-specific recommendations provided below. A summary of compaction requirements for this project is presented in Appendix C. Additional earthwork recommendations are presented in related sections of this report.
7.10.1 Site Preparation and Grading
Prior to the start of grading and subgrade preparation operations, pertinent areas of the Site to be excavated or filled should first be cleared and stripped to remove all surface vegetation, organic-laden topsoil and debris within the project limits. Stripping to a minimum depth of approximately 6 inches is expected to remove a majority of organic laden surficial soils. If significant amounts of organics are encountered below this depth, additional stripping or grubbing may be required. Stripping should extend laterally a minimum of 3 feet beyond the repair limits, where feasible. Stripped topsoil, deleterious matter, and debris should be disposed of offsite; such material should not be reused for backfill. Any buried tree stumps, roots, or major root systems thicker than approximately 1-inch in diameter uncovered during site stripping and/or grading activities should be removed. During the stripping operation, it is important that a representative from BSK be present to observe whether any undesirable material is encountered in the construction area.
Following stripping and removal of deleterious materials, exposed subgrade areas and areas to receive fill should be scarified to a minimum depth of 12 inches, moisture conditioned, and recompacted as indicated in Appendix C unless otherwise indicated by BSK in the field. Scarification and recompaction should extend laterally a minimum of 3 feet beyond the repair limits, where feasible.

Orinda, California Page 17
All fill and backfill should be compacted in lifts of 8-inch maximum uncompacted thickness. A summary of compaction requirements for the project is presented in Appendix C. Laboratory maximum dry density and optimum moisture content relationships should be evaluated based on ASTM D1557.
Proper moisture conditioning is important. After subgrade soils are properly moisture conditioned, their moisture content should be maintained until they are covered by improvements. This may require periodic moisturizing of the subgrade soils if they are allowed to dry. Where aggregate base is used, it should be placed immediately over the prepared subgrade to avoid drying of the subgrade.
All site preparation and fill placement should be observed by a representative from BSK. It is important that a representative from BSK be present during the stripping and scarification process to observe and evaluate whether any undesirable material is encountered in the construction area and that exposed soils and bedrock are similar to those encountered during the field investigation.
7.10.2 Re-Use of On-site Soil and Imported Fill Material On-site soils are considered suitable for re-use as general engineered fill and backfill provided they are free of debris, vegetation, topsoil containing more than 3 percent organic content by dry unit weight, and other deleterious matter. A representative from BSK should be present on-site during grading to visually confirm the suitability of the on-site soil to be used as fill and backfill. Particles larger than 6 inches within the on-site soils should either be removed and disposed offsite or broken down to 6 inches or less prior to using the soil as engineered fill. Nesting (i.e., concentration) of larger particles should be avoided to reduce the potential that this could create voids and allow future settlement in the overlaying fill/backfill.
Maximum particle size for fill material should be limited to 6 inches, with at least 90 percent by weight passing the 1-inch sieve. Where imported fill is required, it should be granular in nature, adhere to the above gradation recommendations, and conform to the minimum criteria presented in the table below.
IMPORTED FILL CRITERIA
Plasticity Index 12 or less
Liquid Limit Less than 30%
% Passing #200 Sieve 8% – 60%
Highly pervious materials, such as “pea” gravel, should not be used as imported fill because they could allow migration of the fine-grained soils into void spaces, thus causing subsidence and settlement of the surrounding area. Imported fill material should not be classified as being more corrosive than “moderately corrosive.” Based on the May 2021 Caltrans Corrosion Guidelines (Version 3.2), we recommend that import fill material have a minimum resistivity greater than 2,000 ohm-cm (per CT 643), a Chloride concentration of less than 250 ppm (per CT 422), a sulfate concentration of less than 500 ppm (per CT 417), and a pH value of between 5.5 and 10.0 (per CT 643). Prior to transporting proposed import materials to the Site, the contractor should make representative samples of the material available to BSK at least 5 working days in advance to allow us enough time to confirm the material meets the above requirements.

Orinda, California Page 18
Additional time may be required if corrosion test results for the proposed imported materials are not readily available at the time the material is submitted to BSK for review. All on-site or imported fill material should be compacted to the recommendations provided in Appendix C.
7.10.3 Weather/Moisture Considerations
Based on our experience in the area, grading during the rainy season (usually November to May) may be extremely difficult due to the type of soil at the Site. If earthwork operations and construction for this project are scheduled to be performed during the rainy season or in areas containing saturated soils, provisions may be required for drying and/or stabilizing the soil through the use of scarification and air drying, geotextile fabric and dryer soils, and/or via admixtures, such as lime- or cement-treatment of the soil prior to compaction. If desired, we can provide recommendations for wet weather earthwork and alternatives for drying the soil prior to compaction. Conversely, additional moisture may be required during dry months. A suitable source should be made available during construction to provide adequate water during earthwork operations.
7.10.4 Excavation and Backfill
We anticipate that excavations for the project can be made with standard earthwork equipment, such as excavators, dozers, and backhoes. Where shallow bedrock is encountered during grading, we expect that it should be rippable with conventional grading equipment as well because the underlying bedrock is generally weak and moderately to highly weathered. However, strong, well-cemented zones of bedrock may be encountered in which difficult excavation may be experienced by the contractor, which may require the use of more powerful earthwork equipment, such as excavators, drill rigs, or hydraulic hammer attachments.
Excavations deeper than 5 feet may become unstable and should be evaluated to monitor stability prior to personnel entering them. All excavations should conform to the current OSHA requirements for work safety. It is the contractor’s responsibility to follow OSHA temporary excavation guidelines and grade the slopes with adequate layback or provide adequate shoring and underpinning of existing structures and improvements, as needed. Slope layback and/or shoring measures should be adjusted as necessary in the field to suit the actual conditions encountered in order to protect personnel and equipment within excavations.
Construction equipment and soil stockpiles should be set back a minimum horizontal distance of “H” away from the edge of excavations and “R” from the edge of the existing culvert walls, where “H” is equal to the depth of the excavation and “R” is equal to the height of the culvert walls. This setback distance also applies to shored excavations unless the shoring design takes into account any surcharge loads associated with the construction equipment and stockpiles.
Care should be taken during construction to reduce the impact of excavations on adjacent structures and pavements. Excavations should be located so that no structures, foundations, and slabs, existing or new, F.4.a

are located above a plane projected 1H:1V upward from any point in an excavation, regardless of whether it is shored or unshored unless otherwise indicated by BSK in the field or by the project plans.
Free groundwater was observed in the boring B-3 at a depth of 8½ feet BGS drilled for this investigation.
However, the actual depth at which groundwater may be encountered in excavations may vary. As a minimum, provisions should be made to ensure that conventional sump pumps used in typical excavation projects are available during construction in case substantial runoff water accumulates within the excavations as a result of wet weather conditions.
Appropriate provisions should be made to prevent surface water from ponding adjacent to the top of excavations and flowing over the sides of the excavations, otherwise the excavation side walls and/or slopes could be compromised. Backfill for excavations should be compacted as noted in Appendix C.
Special care should be taken in the control of excavation backfilling under pavements. Poor compaction may cause excessive settlements resulting in damage to the improvements.
7.11 Corrosion
Soil samples were collected during our subsurface investigation at depths of approximately 13½ and 11 feet BGS at borings B-1 and B-3, respectively, and were submitted for corrosion testing. The samples were tested by CERCO Analytical, a State-certified laboratory in Concord, California, for pH, resistivity, chloride content, and sulfate content in accordance with Caltrans test methods. The test results are presented at the end of Appendix B. Also included is the evaluation by CERCO Analytical of the corrosion test results.
Based upon the resistivity measurements, the samples tested are classified as “moderately corrosive” by CERCO Analytical. The sulfate ion concentrations results were none detected to 18 mg/kg (ppm). These results are indicative of an exposure category S0 per Table 19.3.1.1 of ACI 318-19. For an S0 exposure class, Table 19.3.2.1 indicates that the minimum f’c of the concrete is 2,500 psi. All buried iron, steel, cast iron, ductile iron, galvanized steel, and dielectric coated steel or iron be properly protected against corrosion depending upon the critical nature of the structure. All buried metallic pressure piping, such as ductile iron firewater pipelines, should be protected against corrosion. Because we are not corrosion specialists, we recommend that a corrosion specialist be consulted for advice on proper corrosion protection for underground piping which will be in contact with the soils and other design details.
The above are general discussions. A more detailed investigation may include more or fewer concerns and should be directed by a corrosion expert. BSK does not practice corrosion engineering. Consideration should also be given to soils in contact with concrete that will be imported to the Site during construction, such as topsoil and landscaping materials, which typically contain fertilizers and other chemicals that can be highly corrosive to metals and concrete. Any imported soil or landscaping materials should not be any more corrosive than the on-site soils and should not be classified as being more corrosive than “moderately corrosive.” Also, on-site cutting and filling may result in soils contacting concrete that were not anticipated at the time of this investigation.

7.12 Plan Review and Construction Observation
We understand BSK will be provided the opportunity to review the geotechnical aspects of the project plans and specifications before they go out to bid. It has been our experience that this review provides an opportunity to detect misinterpretation or misunderstandings of our recommendation prior to the start of construction.
Because limited subsurface investigation was conducted for this project, we recommend that BSK be retained to provide observation and testing services during construction. This will allow BSK the opportunity to observe actual conditions exposed during construction and to provide supplemental recommendations if warranted by the exposed conditions. Earthwork should be performed in accordance with the recommendations presented in this report, or as recommended by BSK during construction. BSK should be notified at least two weeks prior to the start of construction and prior to when observation and testing services are needed.

Boring log data represents a data snapshot.
This data represents subsurface characteristics only to the extent encountered at the location of the boring.
The data inherently cannot accurately predict the entire subsurface conditions to be encountered at the project site relative to construction or other subsurface activities.
Lines between soil layers and/or rock units are approximate and may be gradual transitions.
The information provided should be used only for the purposes intended as described in the accompanying documents.
In general, Unified Soil Classification System designations presented on the logs were evaluated by visual methods.
Where laboratory tests were performed, the designations reflect the laboratory test results.
The Responsible Geotechnical Engineer, Professional Engineer, or Professional Geologist uses professional judgement and visual-manual procedures in general conformance with ASTM D2488 to classify soil when the full classification suite of tests per ASTM D2487 is not conducted.

No visible sign of rock material weathering; perhaps slight discoloration on major discontinuity surfaces.
Discoloration indicates weathering of rock material and discontinuity surfaces. All the rock material may be discolored by weathering and may be somewhat weaker externally than in its fresh condition.
Less than half of the rock material is decomposed and/or disintegrated to a soil. Fresh or discolored rock is present either as a continuous framework or as corestones.
More than half of the rock material is decomposed and/or disintegrated to a soil. Fresh or discolored rock is present either as a discontinuos frame or as corestones.
All rock material is decomposed and/or disintegrated to soil. The original mass structure is still largely intact.
All rock material is converted to soil. The mass structure and material fabric are destroyed.

IMPORTANT INFORMATION ABOUT THIS
GEOTECHNICAL-ENGINEERING REPORT
F.4.a
Packet Pg. 116 Attachment: Culvert Wall Repair Memo_081823 (3210 : San Pablo Creek Culvert Repair Project (#4187) Amd. No. 3) Geotechnical-Engineering Report
Important Information about This
Subsurface problems are a principal cause of construction delays, cost overruns, claims, and disputes.
While you cannot eliminate all such risks, you can manage them. The following information is provided to help.
The Geoprofessional Business Association (GBA)
has prepared this advisory to help you – assumedly
a client representative – interpret and apply this
geotechnical-engineering report as effectively as
possible. In that way, you can benefit from a lowered
exposure to problems associated with subsurface
conditions at project sites and development of
them that, for decades, have been a principal cause
of construction delays, cost overruns, claims,
and disputes. If you have questions or want more
information about any of the issues discussed herein,
contact your GBA-member geotechnical engineer.
Active engagement in GBA exposes geotechnical
engineers to a wide array of risk-confrontation
techniques that can be of genuine benefit for
everyone involved with a construction project.
Understand the Geotechnical-Engineering Services
Provided for this Report
Geotechnical-engineering services typically include the planning, collection, interpretation, and analysis of exploratory data from widely spaced borings and/or test pits. Field data are combined with results from laboratory tests of soil and rock samples obtained from field exploration (if applicable), observations made during site reconnaissance, and historical information to form one or more models of the expected subsurface conditions beneath the site. Local geology and alterations of the site surface and subsurface by previous and proposed construction are also important considerations. Geotechnical engineers apply their engineering training, experience, and judgment to adapt the requirements of the prospective project to the subsurface model(s). Estimates are made of the subsurface conditions that will likely be exposed during construction as well as the expected performance of foundations and other structures being planned and/or affected by construction activities.
The culmination of these geotechnical-engineering services is typically a geotechnical-engineering report providing the data obtained, a discussion of the subsurface model(s), the engineering and geologic engineering assessments and analyses made, and the recommendations developed to satisfy the given requirements of the project. These reports may be titled investigations, explorations, studies, assessments, or evaluations.
Regardless of the title used, the geotechnical-engineering report is an engineering interpretation of the subsurface conditions within the context of the project and does not represent a close examination, systematic inquiry, or thorough investigation of all site and subsurface conditions.
Geotechnical-Engineering Services are Performed
for Specific Purposes, Persons, and Projects,
and At Specific Times
Geotechnical engineers structure their services to meet the specific needs, goals, and risk management preferences of their clients. A geotechnical-engineering study conducted for a given civil engineer will not likely meet the needs of a civil-works constructor or even a different civil engineer. Because each geotechnical-engineering study is unique, each geotechnical-engineering report is unique, prepared solely for the client.
Likewise, geotechnical-engineering services are performed for a specific project and purpose. For example, it is unlikely that a geotechnicalengineering study for a refrigerated warehouse will be the same as one prepared for a parking garage; and a few borings drilled during a preliminary study to evaluate site feasibility will not be adequate to develop geotechnical design recommendations for the project.
Do not rely on this report if your geotechnical engineer prepared it:
• for a different client;
• for a different project or purpose;
• for a different site (that may or may not include all or a portion of the original site); or
• before important events occurred at the site or adjacent to it; e.g., man-made events like construction or environmental remediation, or natural events like floods, droughts, earthquakes, or groundwater fluctuations.
Note, too, the reliability of a geotechnical-engineering report can be affected by the passage of time, because of factors like changed subsurface conditions; new or modified codes, standards, or regulations; or new techniques or tools. If you are the least bit uncertain about the continued reliability of this report, contact your geotechnical engineer before applying the recommendations in it. A minor amount of additional testing or analysis after the passage of time – if any is required at all – could prevent major problems.
Read this Report in Full
Costly problems have occurred because those relying on a geotechnicalengineering report did not read the report in its entirety. Do not rely on an executive summary. Do not read selective elements only. Read and refer to the report in full.
You Need to Inform Your Geotechnical Engineer
About Change
Your geotechnical engineer considered unique, project-specific factors when developing the scope of study behind this report and developing the confirmation-dependent recommendations the report conveys.
Typical changes that could erode the reliability of this report include those that affect:
• the site’s size or shape;
• the elevation, configuration, location, orientation,
function or weight of the proposed structure and
the desired performance criteria;
• the composition of the design team; or
• project ownership.
As a general rule, always inform your geotechnical engineer of project or site changes – even minor ones – and request an assessment of their impact. The geotechnical engineer who prepared this report cannot accept F.4.a
Packet Pg. 117 Attachment: Culvert Wall Repair Memo_081823 (3210 : San Pablo Creek Culvert Repair Project (#4187) Amd. No. 3) responsibility or liability for problems that arise because the geotechnical engineer was not informed about developments the engineer otherwise would have considered.
Most of the “Findings” Related in This Report
Are Professional Opinions
Before construction begins, geotechnical engineers explore a site’s subsurface using various sampling and testing procedures. Geotechnical engineers can observe actual subsurface conditions only at those specific locations where sampling and testing is performed. The data derived from that sampling and testing were reviewed by your geotechnical engineer, who then applied professional judgement to form opinions about subsurface conditions throughout the site. Actual sitewide-subsurface conditions may differ – maybe significantly – from those indicated in this report. Confront that risk by retaining your geotechnical engineer to serve on the design team through project completion to obtain informed guidance quickly, whenever needed.
This Report’s Recommendations Are
Confirmation-Dependent
The recommendations included in this report – including any options or alternatives – are confirmation-dependent. In other words, they are not final, because the geotechnical engineer who developed them relied heavily on judgement and opinion to do so. Your geotechnical engineer can finalize the recommendations only after observing actual subsurface conditions exposed during construction. If through observation your geotechnical engineer confirms that the conditions assumed to exist actually do exist, the recommendations can be relied upon, assuming no other changes have occurred. The geotechnical engineer who prepared this report cannot assume responsibility or liability for confirmation-dependent recommendations if you fail to retain that engineer to perform construction observation.
This Report Could Be Misinterpreted
Other design professionals’ misinterpretation of geotechnicalengineering reports has resulted in costly problems. Confront that risk by having your geotechnical engineer serve as a continuing member of the design team, to:
• confer with other design-team members;
• help develop specifications;
• review pertinent elements of other design professionals’ plans and specifications; and
• be available whenever geotechnical-engineering guidance is needed.
You should also confront the risk of constructors misinterpreting this report. Do so by retaining your geotechnical engineer to participate in prebid and preconstruction conferences and to perform constructionphase observations.
Give Constructors a Complete Report and Guidance
Some owners and design professionals mistakenly believe they can shift unanticipated-subsurface-conditions liability to constructors by limiting the information they provide for bid preparation. To help prevent the costly, contentious problems this practice has caused, include the complete geotechnical-engineering report, along with any attachments or appendices, with your contract documents, but be certain to note conspicuously that you’ve included the material for information purposes only. To avoid misunderstanding, you may also want to note that “informational purposes” means constructors have no right to rely on the interpretations, opinions, conclusions, or recommendations in the report. Be certain that constructors know they may learn about specific project requirements, including options selected from the report, only from the design drawings and specifications. Remind constructors that they may perform their own studies if they want to, and be sure to allow enough time to permit them to do so. Only then might you be in a position to give constructors the information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Conducting prebid and preconstruction conferences can also be valuable in this respect.
Read Responsibility Provisions Closely
Some client representatives, design professionals, and constructors do not realize that geotechnical engineering is far less exact than other engineering disciplines. This happens in part because soil and rock on project sites are typically heterogeneous and not manufactured materials with well-defined engineering properties like steel and concrete. That lack of understanding has nurtured unrealistic expectations that have resulted in disappointments, delays, cost overruns, claims, and disputes.
To confront that risk, geotechnical engineers commonly include explanatory provisions in their reports. Sometimes labeled “limitations,” many of these provisions indicate where geotechnical engineers’ responsibilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions.
Your geotechnical engineer should respond fully and frankly.
Geoenvironmental Concerns Are Not Covered
The personnel, equipment, and techniques used to perform an environmental study – e.g., a “phase-one” or “phase-two” environmental site assessment – differ significantly from those used to perform a geotechnical-engineering study. For that reason, a geotechnical-engineering report does not usually provide environmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated subsurface environmental problems have led to project failures. If you have not obtained your own environmental information about the project site, ask your geotechnical consultant for a recommendation on how to find environmental risk-management guidance.
Obtain Professional Assistance to Deal with
Moisture Infiltration and Mold
While your geotechnical engineer may have addressed groundwater, water infiltration, or similar issues in this report, the engineer’s services were not designed, conducted, or intended to prevent migration of moisture – including water vapor – from the soil through building slabs and walls and into the building interior, where it can cause mold growth and material-performance deficiencies.
Accordingly, proper implementation of the geotechnical engineer’s recommendations will not of itself be sufficient to prevent moisture infiltration. Confront the risk of moisture infiltration by including building-envelope or mold specialists on the design team.
Geotechnical engineers are not building-envelope or mold specialists.

SUBJECT: Materials Forensics Services
San Pablo Creek Culvert Distress Evaluation
Orinda, California
Dear Mr. Shick:
At your request, BSK Associates has completed the Materials Forensics Services for the San Pablo Creek Culvert Distress Evaluation located in Orinda, California. Our services were performed as described in our proposal dated February 4, 2022 (Proposal No. GL21-22953), in accordance with the testing program provided by the project structural engineering firm for this project, Finn Design Group Inc. (FDG).
SCOPE OF SERVICES
Our scope of services, as discussed with Mr. Tim Elliott of FDG and described in our proposal was as follows:
1. Destructive Sampling and Testing – Concrete core samples were collected from locations designated by FDG. The cores were drilled completely through each concrete element to evaluate the member thickness. The extracted cores were tested at our materials laboratory for compressive strength testing in general accordance with ASTM C39 and ASTM C42 test procedures. The cores were four inches in diameter.
2. Non-Destructive Location of Reinforcing Steel – A ground penetrating radar unit was used to evaluate the location of reinforcing steel at designated locations on the existing concrete slab and walls of the channel. An approximation of reinforcing steel depth and spacing was made using the results of the scan.
3. Repair of Sampled Areas – A high-strength, non-shrink grout was used to patch all removed concrete at cored or chipped locations during our field visit for destructive sampling and testing.
4. Report - Provide a report including test results and observations related to the project.

PROCEDURE AND RESULTS
On August 25 & 26, 2022, BSK Associates visited the project site to perform the aforementioned scope of services. Upon arrival, we met with Mr. Elliott and reviewed and adjusted the locations where concrete core sampling and rebar scanning were selected by FDG prior to the start of services. The concrete core sampling and rebar scanning locations are shown on Figure 1 – Test Locations.
Non-destructive scanning was performed at each location using a ground penetrating radar unit in order to evaluate the presence and location of the reinforcing steel at each sample location and to avoid cutting reinforcement during the coring operation. Core samples were extracted using a water-cooled, diamondbit core drilling machine. Core samples were collected at Locations #1 through #6 as shown on Figure 1.
As directed by Mr. Elliott, reinforcing steel samples were collected at random locations where the rebar was exposed and was not connected to the concrete at one end. Patching of the cored locations was completed using a high-strength non-shrink grout.
The cores were returned to our laboratory and tested for compressive strength according to ASTM C-39 & C-42 procedures. The reinforcing steel samples were also returned to our laboratory for tensile strength testing in accordance with ASTM A-370.
The results of our observations, measurements, sampling and testing are discussed below and presented on Figure 1 and Appendix A.
Figure 1 – Test Locations – Shows the approximate locations where observations and sampling were performed relative to the testing program plan drawings provided by FDG. Appendix A – Test Reports – Presents the laboratory test reports for the compressive strength and reinforcing steel testing performed.
The tensile strength, yield and elongation test results of the reinforcing steel samples indicate that each of the samples tested meet the criteria for ASTM A615 Grade 40 steel.
OBSERVATIONS
Location 1 – The culvert slab was scanned to locate the steel reinforcement at this location. The reinforcement was found to be approximately six inches on-center in the transverse direction of the culvert and approximately 18 inches on-center in the longitudinal direction of the culvert. The reinforcement is a double mat with the top mat at approximately 2 inches and bottom mat approximately 7 inches from the top of the slab. A core sample was removed from this location for compressive strength testing and to check the thickness of the slab. The thickness of the slab was found to be approximately 11½ inches at this location.
Location 2 – The culvert wall was scanned to locate the steel reinforcement at this location. The reinforcement was found to be approximately eight inches on-center in the vertical direction and approximately 18 inches on-center in the horizontal direction. The reinforcement is a double mat with the mats at approximately 2 inches and approximately 7 inches from the face of the wall. A core sample was removed from this location for compressive strength testing and to check the thickness of the slab.
The thickness of the slab was found to be approximately 10 inches at this location.

PROPOSAL MEMO
VIA EMAIL
DATE: August 18, 2023
TO: T. Ryan O’Kane, PE, City of Orinda
FROM: Ben Shick, PE
SUBJECT: San Pablo Creek Culvert – Proposal for Wall Repair Design and Construction Support Services
Schaaf & Wheeler is pleased to provide you with this scope and fee to provide additional services for the City of Orinda, San Pablo Creek Culvert Repair Project. The additional services include preparing design documents for the recommended repairs to the leaning walls within the culvert, and to provide biological compliance support services for the project. The work will be performed in conjunction with the previously approved tasks. It is assumed that the design for the leaning wall repairs will be completed with one set of bid documents with the culvert invert repairs being designed under previously approved tasks.
Schaaf & Wheeler will provide the following tasks for the fee identified in the attached table.
Task 1: Leaning Wall Design
Schaaf & Wheeler and structural engineering subconsultant, Peoples Associates Structural Engineers (PASE, formerly Finn Design Group) will prepare construction documents for the recommended repairs to the leaning walls as outlined in the memorandum dated August 18, 2023. The repairs will include 10 steel beams spanning across the culvert and a continuous concrete beam along the top of the wall. Plans, specifications, and estimates will be submitted at the 100% draft and final bid document phases.
An additional site visit will be performed during the dry months of 2023 to document the existing conditions and to determine if any additional erosion or damage occurred during the previous winter.
Task 2: Biological Compliance Support Services (Year 1 Construction) Schaaf & Wheeler’s subconsultant, WRA Environmental Consultants, will provide the following scope of services for the anticipated biological compliance requirements of the project. This scope of services assumes that the construction contract will take two construction seasons to complete. This task covers the anticipated scope for year 1 of the construction contract.
Task 2A: WEAP Training Session for Personnel
Per Measure 6 of the USFWS Concurrence Letter, a qualified biologist from WRA will develop a Worker Environmental Awareness Program (WEAP). The WEAP will include a discussion of the biology and general behavior of any sensitive species that may be in the area, how they may be encountered within the work area, and procedures to follow when they are encountered.
Translation into any other language will be provided by a member of the crew; if translation into F.4.b

Schaaf & Wheeler 2
Spanish is required, WRA can provide this service for an additional fee. This task will require one (1) site visit to provide the WEAP in person to construction personnel no later than the first morning prior to the start of work.
Task 2B: California Red-legged Frog, Alameda Whipsnake, and Nesting Bird Survey Per Measure 7 of the USFWS Concurrence Letter, a qualified biologist from WRA will conduct a survey for California red-legged frog (CRLF) and Alameda whipsnake (AWS). The survey will be conducted at least 14 days prior to the commencement of ground-disturbing activities. This survey will cover the Project area and 200-feet upstream and downstream of the Project area for CRLF and AWS individuals. If CRLF or AWS are observed at any time during the preconstruction survey efforts or the biological monitoring, they shall be allowed to move off site on their own volition and USFWS will be contacted for next steps. Following the survey, the qualified biologist will establish 12 photo points and take the pre-construction photos as required by RWQCB Measure 13.
Per Measure 5 of the USFWS Concurrence Letter and the CEQA Project Description, if construction is scheduled between February 1 to August 31, a qualified biologist from WRA will conduct a nesting bird survey within 14 days of the start of construction. To reduce costs, this survey will be conducted during the same site visit as the CRLF and AWS survey. The survey area will include a 500-foot buffer of the project site. Per Measure 5 of the USFWS Concurrence Letter, if active nests are detected, the qualified biologist will set an appropriate buffer distance or “No Work Zone” until the chicks have fledged or the nest otherwise becomes inactive. The buffer distance will be established by the biologist based on factors such as the species observed, type of adjacent disturbance, and sensitivity of the nesting bird to disturbance. This task does not include separate site visits to monitor the nests, should separate site visits be necessary, WRA can conduct these efforts for an additional fee.
One letter report will be prepared following the survey to document the methods and results of the CRLF, AWS, and nesting bird (if conducted) surveys. The survey will be sent to the City for compliance records.
Task 2C: As-Needed Agency and Client Coordination
WRA will conduct agency notifications and coordination, including the RWQCB commencement of construction notice per Measure 12. This task also includes coordination with the Schaaf & Wheeler and City, scheduling, coordination with the construction contractor, invoicing, and other project management tasks. One site visit is included in this task for a post-construction site walk and photo point documentation (RWQCB Measure 13) at the end of the Year 1 work season. In addition to the site meeting and agency notifications, this task assumes up to 20 additional hours of project management and communications may be needed. No annual postconstruction report is required by RWQCB, but a final post-construction report will be completed following the full project completion and is included in Phase 5 Task 3. If additional needs arise that will require time commitments greater than this amount, these can be addressed for an additional fee.
Task 3: Biological Compliance Support Services (Year 2 Construction) Schaaf & Wheeler’s subconsultant, WRA Environmental Consultants, will provide the following scope of services for year 2 of the construction contract.

If construction is scheduled to be reinitiated between February 1 to August 31, a nesting bird survey will be conducted simultaneously as the CRLF and AWS survey. Following the surveys, the biologist will take photos at the established photo points for use in the postconstruction report. One letter report will be prepared describing the methods and results of the surveys. The surveys and letter report will be conducted as described above in Task 2B.
Task 3C: Agency Coordination and Post-Construction Reports WRA will conduct agency notifications and coordination, including the RWQCB annual commencement of construction notice per Measure 12. One site visit is included in this task for a post-construction site walk and photo point documentation (RWQCB Measure 13) at the end of the Year 2 work season. Following completion of construction in Year 2, an as-built report including the pre- and post- photo documentation will be prepared in accordance with RWQCB Measures 13 and 14. This task will require coordination with the project construction contractor and/or engineer for the final plan set with mark-up on changes during construction.
Separate notices of completion are required for RWQCB (Measure 15) and for the Corps, and WRA will coordinate and submit these notices.
Task 3D: Project Management and Coordination
This task includes coordination with Schaaf & Wheeler and City, scheduling, coordination with the construction contractor, invoicing, and other project management tasks.

Staff Report
Agenda Item: G.1
Date: September 19, 2023
Department: Planning Department
AGENDA TITLE: (a) Discussion of a proposed dedication of a portion of the parcel at 11 Orinda Way (Chevron Station) that was part of a convenience market project approved by the Planning Commission, contingent upon City Council adoption of Ordinance 23-04; and (b) Public Hearing regarding Ordinance 23-04 which would Amend Section 17.2.3 (Definitions) and Section 17.8.5 (Downtown commercial district— Use restrictions) of the City’s Zoning Code to Update Rules Applicable to Convenience Markets and Other Ancillary Retail Uses at Service Stations (applicant: Chevron).
RECOMMENDATION:
Staff recommends that the City Council 1) consider the question of the dedication of the creek portion of 11 Orinda Way as fee or through an easement; 2) waive the full reading of the text and introduce Ordinance 23-04, amending Section 17.2.3 (Definitions) and Section 17.8.5 (Downtown commercial district-Use restrictions) to update the City’s rules regarding convenience markets and other ancillary retail uses at service stations; 3) find this ordinance is not subject to the California Environmental Quality Act (“CEQA”) pursuant to CEQA Guidelines (Title 14 of the California Code of Regulations) Sections 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) because it has no potential for resulting in physical change in the environment, directly or indirectly.
BACKGROUND:
Service station convenience markets are a conditionally-permitted use in the Downtown Commercial District but may not exceed 40 square feet in size pursuant to Orinda Municipal Code (OMC) Subsection 17.8.5-H.2. This Zoning Text Amendment, sponsored by Chevron Products Company, would allow convenience markets larger than this as a conditionally-permitted use at service stations, subject to a use permit with new required criteria. Highlights of the proposed changes include:
1. Eliminate the 40 square-foot limitation to convenience market sizes at service stations as well as minimum distances to other land uses such as churches and schools.
2. Allow convenience markets at service stations subject to the following:
a. Require a noticed public hearing for a commercial use permit; b. Be 2,250 – 3,000 square feet (but no more than 20% of a lot size); c. Contain a pedestrian entrance within 35’ of public right-of-way (ROW); d. Provide at least 25’ of frontage to the ROW; and
e. Require the inclusion of “fresh food”
3. Change the definition of liquor store to clarify that a liquor store primarily sells alcoholic beverages for off-site consumption.
G.1
Packet Pg. 141
This Zoning Text Amendment was initially presented to the Planning Commission in conjunction with a proposed development project at 11 Orinda Way (the Chevron service station). This project included the conversion of the existing service bay area into a convenience market. Proposed changes include interior and exterior remodel of the building, modification of the fuel canopy, construction of an observation deck, site improvements, installation of an additional fueling station, and installation of an electric charging station. The property owner also proposed to dedicate a portion of the site to the City that contains San Pablo Creek for future restoration and public access. The Commission approved this project and no appeal was filed.
Following is a brief timeline of the project:
• February 9, 2021: An early version of the project was presented to a joint meeting of the Orinda Planning Commission and City Council. The minutes of this meeting are included as an attachment to the July 12, 2023 agenda (Weblink - Attachment D)
• November 29, 2022: A second iteration of the Chevron proposal was presented to the Planning Commission and continued for changes. The minutes of this meeting are included as an attachment to the July 12, 2023 agenda (Weblink - Attachment D)
• March 24, 2023: The applicant withdrew and resubmitted the project to benefit from AB-2097 state legislation that went into effect on January 1, 2023. AB-2097 eliminates automobile parking requirements for most development projects located within ½ mile of public transit.
• July 12, 2023: The project was presented to the Planning Commission. During the public testimony portion of the hearing, 12 members of the public spoke in favor of the project and the code amendment and one member of the public spoke in opposition. The Planning Commission adopted a Statement of Official Action (Attachment C) approving the entitlements for the project. Additionally, with 5 Commissioners voting in favor, one against, and one absence, the Planning Commission adopted PC Resolution 23-03 recommending the City Council adopt an Ordinance for Zoning Text Amendment ZTA-2023-001 (Attachment B). Action on the project is contingent on City Council approval of the proposed text amendment to Orinda Municipal Code Section 17.8.5.
DISCUSSION:
The discussion is arranged in three sections: Section 1: Zoning Text Amendment description; Section 2: General Plan Consistency, applicability & additional impact, and OMC intent; and Section 3: Staff discussion of the Chevron-proposed dedication.
Section 1: Zoning Text Amendment description
The applicant is seeking a Zoning Text Amendment to the definition of “Convenience Market.” Under the existing Orinda Municipal Code (OMC), a convenience market is a conditionally-permitted use in the DC district, provided that it complies with the additional requirements as stipulated in Subsection 17.8.5H.2 of the OMC, including:
G.1
Packet Pg. 142
• A maximum size of 40 square feet;
• A prohibition within the immediate vicinity of a church or hospital, or within 600 feet of a school, public playground, or nonprofit youth facility; and • A prohibition on any variance permit for these standards.

General Plan Consistency
The proposed Zoning Text Amendment would be consistent with and promote the following policies identified below:
• 2.1.3 Downtown: Guiding Policies
o (B) Favor retail services needed frequently by residents by limiting the amount of office space in predominantly retail areas. Office space in retail areas should serve Lamorinda uses and generally not exceed retail space on any one lot.
o (E) Make downtown shopping more attractive by diverting through traffic off local streets in the business district, providing more convenient circulation for shopping traffic, managing the parking supply more efficiently, creating safe and pleasant pedestrian routes, and developing and maintaining sufficient landscaping.
• 2.1.4 Downtown: Implementing Policies
G.1
Packet Pg. 145
o (E) Enact regulations that will ensure that the central business area will be predominantly retail and which permit only a limited amount of offices that favor local use needs.
Applicability & additional impact
The proposed amendments may be applicable to the existing service stations in Orinda, as indicated in Table 1.
Table 1: Existing Service Stations in Orinda
Address Service Station Lot Size (Sq. Ft.)
11 Orinda Way Chevron 35,118
9 Orinda Way Shell 28, 750
67 Moraga Way 76 14,375
22 Bryant Way Mash Gas & Food 14,289
Additional impact on alcohol sales
The State of California grants local government wide latitude to regulate alcohol sales through discretionary permitting processes such as conditional use permits. In addition, alcohol sales are regulated by the Department of Alcoholic Beverage Control (ABC).
However, in the mid-1990s, the state legislature amended part of the ABC code to limit local authority over off-premise sale of beer and wine at service stations. The new law stated, in part, that “no city, county, or city and county shall, by ordinance or resolution adopted on or after January 1, 1988, legislatively prohibit the concurrent retailing of motor vehicle fuel and beer and wine for off-sale consumption in zoning districts where the zoning ordinance allows motor vehicle fuel and off-sale beer and wine to be retailed on separate sites” (Alcoholic Beverages Code, Chapter 5, Article 1, 23790.5(2)). The same state regulation also establishes the minimum 5-foot distance between a cashier or front door and any alcohol displayed for sale. In adopting the prohibition on convenience markets over 40 square feet, the Orinda City Council also ensured that alcohol sales would not take place at service stations.
Although the State preempts local control of alcohol sales at convenience markets, ABC has its own permitting process that still applies, based on the type of alcohol sales proposed and the location of the business; proximity to schools and churches is one of the factors ABC considers. Although ABC allows a person to protest the issuance of a liquor license based on location, according to ABC staff there is no guarantee that a license will not be issued because of the proximity to a business to a church, school, public playground, or nonprofit youth facility.
Amending the 40 square-foot limit on convenience markets at service stations to allow larger markets limits the City’s ability to control alcohol sales at these establishments.
G.1
Packet Pg. 146
Currently alcohol sales are technically permitted, however the maximum size of 40 square feet effectively bans alcohol sales as it would be difficult to meet a state requirement that prohibits alcohol sales within 5 feet of a front door or a cash register at service stations.
Conformance to OMC Downtown Districts intent
The proposed text amendment requires that a convenience market at a service station be consistent with the OMC intent section at the beginning of the Downtown Districts chapter of the zoning ordinance. The Downtown intent section in its entirety is as follows:
17.8.1 Intent.
In addition to the general purposes listed in Chapter 17.1, the specific purposes of the downtown district regulations are to:
A. Create every opportunity for the downtown area to function as a vital, thriving yet traditional Main Street area, serving local needs and providing for specialty retail activities, consistent with the general plan;
B. Create a vibrant community center by encouraging a variety of businesses which will create pedestrian interaction and pedestrian-scale activities. Emphasize uses which involve pedestrian spaces, including outdoor dining, garden settings, walkways and seating areas;
C. Encourage areas of distinctive character by identifying preferred uses and development standards unique to these locations;
D. Regulate development so as to achieve a vibrant community center over time. All development, including incremental development, small building additions or increases in intensity of existing land uses, shall be consistent with this goal; E. Establish incentives, such as additional building height, higher floor area or broader range of permitted uses to help achieve a vibrant community center; F. Discourage and eventually terminate nonconforming office uses in retail spaces; G. Establish development standards which define desired character, but which allow and encourage flexibility in how this character is to be achieved, including standards involving building heights, setbacks, site planning, building bulk/mass, landscaping, parking, lighting and architecture, as presented in the downtown design guidelines;
H. Protect adjoining residential areas from inappropriate or disruptive commercial or office activities;
I. Encourage parking solutions which will serve long-term needs and will minimize the adverse effects of parking, traffic and circulation on the function and viability of downtown;
J. Encourage activities and development which will showcase the creek, where possible, for low-intensity pedestrian-oriented activities and strolling; K. Provide for multifamily housing, including affordable housing, in downtown areas, consistent with the housing element of the general plan.

Section 3: Staff discussion of a Chevron-proposed dedication The proposed remodel of Chevron includes a discretionary Zone Text Amendment to change the City’s code to allow for the Convenience Store proposed. The Planning Commission has recommended that Zoning Text Amendment to the City Council. In a related action, the Planning Commission also approved the Conditional Use Permit and other entitlements for the project, contingent on Council approval of the proposed Zoning Text Amendment. The CUP and related entitlements were not appealed by the deadline; however, the Zoning Text Amendment does require a separate City Council consideration and action.
As part of the project consideration, Chevron has offered a portion of their property along the creek for dedication to the City in fee, along with an easement for access from Orinda Way. Staff supported the easement for access from Orinda Way, but recommended at the Planning Commission that the City should ultimately accept an easement that would allow for public access along the creek, not fee title. Chevron did not agree to Staff’s recommendation that access along the creek be addressed through an easement, and the Planning Commission opted to approve the project as requested by Chevron with an offer of a fee dedication.
City staff opted to not appeal the CUP and other entitlements approved by the Commission as we knew that there was the discretionary Zoning Text Amendment pending, and that Council could consider the matter as part of that item, and we did not want to give rise to any broader considerations as would have occurred through an appeal. This is because Staff is very supportive of the Chevron project and the sole area of disagreement is the form in which public access along the creek would be handled. As such, Staff would recommend that if the Council approves the Zoning Text Amendment then it provide direction to Chevron that the City will ultimately only accept an offer of dedication for public access to the creek via easement, not fee title.
The City already has an easement on a portion of the subject property for flood control purposes, however, the underlying fee remains in the ownership of Chevron.
Easements are quite commonplace for the trails and open space. Advantages for the City in the easement approach include:
• The City’s liability is limited to that related to the public use of the parcel, issues like soils contamination (this is a service station site), and possible issues associated with flooding or land subsidence would remain with the property owner;
• The property stays on the tax rolls and will generate property tax; • The desired public use and access can be fully accommodated through an easement with the property owner provided with indemnity language from the City for that use;
• Grant of other funds can be secured through an easement as well as through ownership approach;
• There is no need to undertake any type of lot line adjustment or parcel split; G.1
Packet Pg. 148
• The property owner (Chevron) would remain responsible for annual fire fuels reduction and basic maintenance of the parcel;
• Regional Regulatory Agencies like Fish & Wildlife, the Regional Water Quality Control Board, and others, would look to the property owner to meet their requirements.
It should be noted that acceptance of an offer of dedication (of either fee or easement) would be a discretionary action of a City Council at a future date and in keeping the current approval intact does not commit the City to accepting any offer of dedication. An offer of dedication would also require that at the time of dedication, if accepted, that the appropriate language regarding indemnification for the City and other concerns be addressed through the appropriate instruments, together with any necessary adjustment of the parcel lines being completed through the correct vehicle. The main difference in approach, is which entity to assuming the greater risk/responsibility.
From staff’s perspective, the property along the creek is not being offered for dedication by Chevron to the City because it is a prime parcel without any encumbrances or constraints, but rather because it is transferring certain types of liability and cost issues to the public via the City.
At the time of a project’s approval, these types of concerns often don’t rise to the forefront of the decision maker minds. However, a few years down the line, or sometimes even decades later, when something occurs or the City is exposed to unanticipated costs, it is important that there be a record of these considerations having been identified and factored into the decision making process.
PUBLIC COMMENT:
