Agenda packet — Coronado City Council, July 18, 2023 (part 4 of 4)

Chronology of Site Surveys Performed to Date
Memorandum to Jim Heintz from Dudek dated 9/1/22
The first study prepared for the subject property consisted of a ‘memorandum’ commissioned by an adjacent homeowner purporting to detail community noise conditions in, and around, the subject property. This memorandum provides a mixture of dubious aggregate short- and long-term acoustical measurements, concluding that the facility is in non-compliance.

Forensic Investigation from ISE to Sunset West Development dated 1/15/23 The second assessment prepared for the subject property was performed by ISE on 1/15/23, in response to the project operator receiving the NOV. This forensic assessment identified the subject area as a highly-acoustically-contaminated area, suffering from past encroachment on the subject property; excessive surface street traffic noise; high levels of structural reflection; military overflight noise; fixed operational noise exceedances, and landscaping noise, from the adjacent condominium use; nonpermitted loading dock operations; and non-code-compliant music levels from adjacent gymnasium uses.

As a result of the high level of acoustical contamination, and the refusal of the City of Coronado to communicate any specific information regarding the nature of the perceived violation, ISE was forced to acoustically isolate the subject property operations to determine just the noise produced by the subject property, per the requirements of Municipal Code Section 41.10.010. ISE identified that one complete car wash cycle, sans any surrounding community sources, multiplied by the yearly average hourly throughput of the facility, resulted in aggregate hourly noise levels of 59.7 dBA Leq-h, and was compliant with the CUP at the closest property line.

Noise Measurement Study from RECON dated 5/25/23
Finally, as a result of the ISE report, the City of Coronado commissioned its own technical report. This study, prepared by RECON, by-and-large replicated the same technical mistakes seen in the 9/1/22 Dudek memorandum, with the perplexing addition of computer-generated findings for operational events at the facility that did not occur.

Ironically, the RECON report, while concluding non-compliance of the subject property, arrived fundamentally within the same range of acoustical levels as the ISE report, but attributes the difference between the two reports to two minor points – which are also incorrectly stated in the RECON report.

Technical Opinions Regarding the NOV and Chronology
Based on the above review, it is this author’s opinion, that the subject property, as currently operated, does not constitute a violation as defined under the CUP or Municipal Code Section 41.10.010. The following conclusions are cited in support of this statement.

The City of Coronado Issued a NOV without Proper Due Diligence.

Based on the document trail, the City of Coronado acted in an arbitrary and capricious manner by sending the project operator a NOV based solely on a complaint from the public, without either vetting the accuracy of the data contained within the complaint, or performing their own due diligence analysis prior to issuing the NOV.

The City of Coronado Demanded Acoustical Remedies without Defining the Problem.

The City states that the subject property contained “pressure washers” and “blowers” in violation of the CUP, and demanded correction of these ‘defects’, without ever verifying that the aforementioned equipment was the cause, and refusing to discuss specifics of the problem with the project operator, or their acoustical engineer. This finding and demand on the part of the City is remarkable in that the independently-contracted ‘memorandum’ provided to the City by Dudek never performed any testing to uniquely isolate what purported noise source was the problem: blower, washer, or otherwise.

The 9/1/22 Dudek Memorandum Contains Numerous Technical Anomalies.

The 9/1/22 Dudek memorandum, upon which the City purportedly based its NOV, contains numerous technical anomalies guaranteed to give artificially high noise readings and incorrect results. These errors include: improper meter placement and orientation, incorrect time constants applied to the monitoring equipment, artificially time-limited measurement not consistent with Municipal Code Section

41.10.010, incorrect calculation metric, and utilizing a wholly uncontrolled test environment.

The 9/1/22 Dudek Memorandum Never Really Measured the Noise from the Subject Property.

The Dudek memorandum, while heavy on small, time-sliced, sampling data, and using the wrong time constant, never actually measured the acoustical exposure from the subject property. Instead, it provided a computer-generated predicted response using what the author describes as being, “Consistent with acoustic principles...” This statement in the report (i.e., ‘consistent with acoustic principles’) appears to be a nonsensical bridge to jump from dubious field data to a final conclusion, without the benefit of the necessary scientific framework to make a compelling argument.

The Balconies of the Condominium Development Area are not Sensitive Use Spaces.

The 9/1/22 Dudek memorandum, upon which the City purportedly based its NOV, took all of it measurements from elevated receptor locations within the balcony areas of the condominium development. Not only do the chosen locations artificially increase the community noise received by the meters, the area itself (e.g., the balconies) would not be considered sensitive use space, either under the City’s General Plan, or the State of California, as based on the completion date of the condominium development with respect to the subject property, no acoustical mitigation was applied to these balcony spaces, as required by the City, nor is there any apparent architectural mitigation for the condominiums consistent with CCR Title 24, Part 2 (1974) requirements.

The 5/25/23 RECON Report Replicates Numerous Technical Mistakes Seen in the Dudek Memorandum.

The 5/25/23 RECON report makes some of the same measurement mistakes as the Dudek memorandum, although they do correctly apply the proper time constant to the equipment they are using. Unfortunately, this report also applies an incorrect integral summation of acoustic pressures in a highly confined, high community noise environment, making any disaggregation of the data impossible, due to lack of experimental controls. These errors include, but are not limited to: improper meter placement, artificially time-limited measurements not consistent with Municipal Code Section 41.10.010, incorrect calculation metric, and utilizing a wholly uncontrolled test environment (but with far better controls than the Dudek memorandum).

The RECON Report Does Not Make the Argument for an Impact Further, the RECON report appears to utilize its somewhat-contaminated field data to calculate the requisite subject property operational throughput, and concludes an impact by virtue of false reasoning, by reverse engineering an acoustical metric. This would imply that the author is uncertain as to whether there’s an impact or not, instead providing tables of possible scenarios upon which the subject property would either comply with the CUP, or not comply.

Ironically, using this peculiar approach, Table 4 of the RECON report provides similar findings to the ISE report for an average throughput of 10 vehicles per hour (i.e., no acoustical impact).

The RECON Report Erroneously Describes the Differences Between their Report and the ISE Report.

Finally, the RECON report makes two assumptions in its report not supported by physical evidence, or in direct contradiction to physics.

First, while identifying that their findings, and the ISE findings, are very similar, they ascribe the difference as being due to their claim that ISE applied the wrong propagation coefficient. This is incorrect. The propagation coefficient applied is consistent with a spherical point source close to the ground. The RECONreferenced propagation rule only applies to spherical propagation with no interference in the wavefront (i.e., slow moving aircraft or elevated point source).

This is not the case for a sound level meter positioned on a tripod above the ground as was done in the ISE report, and the RECON report for that matter. In fact, one can even demonstrate that the propagation rule applied by ISE is wholly conservative as noise leaving the subject property is actually hemispherical in nature, producing even greater levels of attenuation.

Secondly, the RECON report, in an attempt to justify an impact when their regenerated data showed findings consistent with the ISE report, makes an arbitrary statement that, “The actual number of maximum hour car washes is not known, and may be greater than 10”, and then applies a capricious finding that, “…more than 10 washes per hour could occur during busy days.” This is incorrect in that all environmental compliance studies, consistent with CEQA, rely on the necessary condition that the project operates in a reasonable and foreseeable manner, thereby allowing the determination of whether a facility is operating in substantial conformance with its permit requirements.

Based on a review of operational records, performed by ISE, the subject property was found to have serviced a total of 46,576 cars in FY 2022. This equates to approximately 127.6 cars per day over 13 hours of operation, or 9.81 cars per hour. While ISE does not dispute that some random hours can have more than 10 vehicles, it is also true that quite a few hours of operation have far less than this as well. Thus, an average of 10 cars per hour for the purposes of determining conformance with the CUP is fully acceptable under CEQA.

Should you have any questions regarding these findings, please do not hesitate to contact me.

Rick Tavares, Ph.D.

ISE claims that the RECON report does not make an argument for an impact and reverse engineers an acoustical metric. RECON disagrees with this claim. Additional calculations were conducted in the RECON report in order to arrive at a level of car wash activity that would result in an exceedance of the property line noise level limits. This was done because car wash activity naturally varies hour-by-hour, day-by-day, season-by-season. If it can reasonably concluded that a peak hour car wash activities exceeds the number of washes per hour provided in the RECON report, then the property line noise level limit is exceeded.

ISE disagrees with the propagation coefficient used in the RECON analysis (i.e. 20Log(D1/D2)). This is an industry standard propagation rate reflective of a hard site environment, and is supported by technical documentation including Caltrans Technical Noise Supplement to the Traffic Noise Analysis Protocol. It is representative of spherical propagation, as mentioned by ISE. The sources of noise are elevated above the ground and noise does spread in a spherical manner. Further, as discussed in the RECON report, this propagation rate matches the measurement data well as evidenced by the measurements taken of the Tunnel 2 blower at measurement locations 2 and 3.

Lastly, ISE claims that the RECON report makes an arbitrary statement about the number of car washes per hour. This is untrue. ISE arrived at 10 car washes per hour using annual wash data and assuming an even distribution of car washes over all days of the year and all hours of each day. This is not representative of actual car wash operations.

For example, more car washes may occur during peak weekend days and afternoon hours than would occur during early morning or late night hours. The Municipal Code and Special Use Permit noise level limits apply to any hour between 7:00 a.m. and 10:00 p.m.

Mr. Jesse Brown
Senior Planner
City of Coronado
Community Development Department
1825 Strand Way
Coronado, CA 92118
Reference: Philthy Philz Car Wash Noise Compliance (RECON Number 9641-1) Dear Mr. Brown:

RECON Environmental, Inc. (RECON) has reviewed the letter prepared by Investigative Science and Engineering, Inc. (ISE) dated June 8, 2023. In response to some of the claims raised in the letter, we provide the following responses:

ISE claims that RECON’s report “applies an incorrect summation of acoustic pressures in a highly confined, high community noise environment, making any disaggregation of the data impossible, due to lack of experimental controls. These errors include, but are not limited to: improper meter placement, artificially time-limited measurements not consistent with Municipal Code Section 41.10.010, incorrect calculation metric, and utilizing a wholly uncontrolled test environment”.

RECON disagrees with these claims. Noise meters were placed at the property line in accordance with the Municipal Code and Special Use Permit, and noise levels were measured for over a one hour period. Table 1 of RECON’s report presents the measured noise level at the property lines, all of which exceeded 60 dB(A) Leq. Since there are other sources of community noise in the area and the car wash is not located in a noise vacuum, noise measurements cannot be taken of car wash activities alone. Therefore, calculations were conducted to arrive at the ambient noise environment. As described in the RECON report, detailed notes about every car wash noise event were taken and time periods were removed from the measurement data, resulting in a reasonable approximation of the ambient noise levels. These noise levels are presented in Table 1. The measured noise level due to car wash activities alone can be determined by subtracting the ambient noise level from the overall measured noise level. These noise levels due to car wash activities are also presented in Table 1. As shown, these car wash only noise levels exceeded 60 dB(A) Leq at the property line during the observed measurement period.

CITY COUNCIL STAFF REPORT

REQUEST COUNCIL DIRECTION FOR FINAL DESIGN AND AUTHORIZE BID

ADVERTISEMENT FOR THE LAWN BOWLING GREEN TURF REPLACEMENT PROJECT RECOMMENDATION:

Provide direction for final design to complete the bid documents and authorize bid advertisement for the Lawn Bowling Green Turf Replacement project using two bid packages: 1) Install concrete root barriers and drainage system; and 2) Remove existing turf, repair/replace existing base, install new turf. In addition, staff requests Council provide direction on the proposed removal of the leaning torrey pine tree P-56.

BACKGROUND:

In 2010, the John D. Spreckels Center’s (JDSC) Lawn Bowling Green complex (Complex) was constructed. The construction replaced the existing turf surface with an artificial surface (Green).

The Green had a 10-year life expectancy.

In September 2019, staff responded to a request to investigate numerous mounds that had developed under the Green on the D Avenue side of the Complex. Approximately twenty mounds were identified ranging from as small as a golf ball, to the size of a softball, thus rendering portions of the Complex unplayable. The mounds were the result of the puffball mushroom fungus Pisolithus arhizus/tinctorius (common name: dyeball or deadman’s foot fungus). Staff temporarily slowed the progress of the fungus through fungicidal injections, but this process required puncturing the Green numerous times and was detrimental to the playability and longevity of the Green.

On February 16, 2021, staff presented an overview of the project to Council and stated that the fungus lived on both live and dead conifer tree roots. Staff recommended the removal of the four canary pine trees on D Avenue, installation of a (root) barrier along the north side of the Green, replacement of the substrate and Green, and installation of a pump to divert the drainage away from the Green that was coming from the JDSC roof and being treated by the northerly planter.

In the Analysis portion of the staff report, staff included the following: “At this time, there are no known remedies for the fungus and eradication is difficult to impossible. The more mitigation measures employed, the greater the opportunity for success.” The Council discussed staff’s recommendation and alternatives provided by the West Coast Arborists, Inc. (WCA) report (Attachment 1). Discussion also centered around the Rutgers University and PACE Turf, LLC (excerpts included in the WCA report), both of which did not provide confidence that there was a definite solution to the issue. In a 3-2 vote, the City Council supported staff’s recommendation with the exception of the removal of the trees. In addition, direction was provided to design a barrier of some sort (concrete, gravel, etc.) to prevent roots from reaching the Green, within a reasonable budget.

Over the course of approximately a year and a half the city saw a significant amount of turnover in personnel involved in the project which resulted in significant delays. Due to the timing of onboarding of new staff in multiple departments, management of the project was moved from City of Coronado Page 967
Recreation and Golf Services to Public Services and Engineering.

On June 7, 2022, City Council approved a contract with Nasland Engineering to design and prepare the bid documents.

From late June to November of 2022, city staff and the consultant prepared draft design documents and met with the Coronado Lawn Bowling Club (bowlers) regarding the project. In discussions with the bowlers every facet of the project was questioned. This included: the cause and nutrient source of the fungus, use of herbicides/barriers on the Green, use, placement, and depth of the root barriers, determining tree health and need for tree protection, need for a drainage system under the Green, replacement of the hedges, and much more. Ultimately it was determined that definitively identifying the cause and nutrient source of the fungus was the most important factor to address these questions and ensure the optimal design solution was reached.

Because there were differing opinions and no conclusive solution from the original consultants on the project (Rutgers, Pace Turf, WCA), staff decided to obtain more definitive research. Pace Turf recommended a mycologist-plant pathologist who is an expert on the specific mushroom, pisolithus arhizus/tinctorius that is invading the City’s lawn bowling green.

Staff contacted Ms. Pat Nolan, who spent 27 years as a plant pathologist in the Department of Agriculture, Weights and Measures for the County of San Diego including work in mushroom identification. Now retired, she continues to use her mycological skills in mushroom identification as a long-time member of the San Diego Mycological Society, and especially in unusual cases.

For this project, she has and continues to volunteer her time.

On February 9, 2023, staff, consultants, bowlers and Ms. Nolan visited the Complex. Ms. Nolan confirmed the other consultants’ findings: a symbiotic “mycorrhizal” relationship exists between the fungus and the nearby conifer trees growing along D Avenue and adjacent to the Library. But she added an important distinction: this mushroom is created only on living roots and not dead roots or organic debris (Attachment 2). Staff also received a second confirmation from a microbiology and plant pathology professor at UC Riverside (Attachment 3). Therefore, excavating the soil beneath the green to remove all dead organic matter and fungal spores is not necessary as this fungal mushroom will not fruit or multiply unless a living root is present to supply it with nutrients.

ANALYSIS:

Given this new knowledge about the specific mushroom invading the City’s turf, staff was able to tailor a new solution. Based on the collective opinion of the involved parties and the City, staff recommends splitting the original project into two bid packages with the following scopes of work:

Phase I

1. Construct a concrete barrier along D Avenue and the Library to block root intrusion from nearby trees.

2. Complete the roof drain system by installing a pump to redirect water away from the Green.

Phase II

3. Remove existing Green exposing the base material, repair base material as needed.

4. Install new Green.

By splitting the project into two, each of the projects can be completed by contractors who perform work within their expertise. Separately, the root barriers can be installed as one of the first items City of Coronado Page 968
of work which would provide an opportunity to visually observe the quantity and size of the roots under the Green coming from the trees. Applying herbicide to the roots at this time will also be considered.

Staff believes that constructing a concrete root barrier at a depth of five feet in conjunction with WCA recommendations for tree health will reduce/prevent tree roots from growing under the Green. The consensus from speaking to several arborists is that tree roots are generally two to two and half feet deep. Staff does not believe roots from the hedges along D Avenue are a source for the fungus under the Green.

Staff reviewed the option of placing a concrete/gravel barrier beneath the Green, but significant costs were a concern along with feedback from the bowlers that this was not preferred. A drain system was also considered; however, it added additional costs and was also not preferred. In general, preserving the existing base to the Green was preferred by the bowlers.

In the course of significant coordination and interaction with the bowlers to understand the issues and with a goal to construct a project that met their needs, the bowlers made one request: to remove the four canary island pine trees (F-9 through F-12) thereby eliminating any possibility of tree roots intruding under the Green and averting the need to install a concrete root barrier along D Avenue. It is also staff’s understanding that these trees add maintenance duties due to the trees dropping sap and leaves onto the Green.

Lastly, as part of staff’s review of the project, the health of one of the torrey pines was questioned.

The arborist working under Nasland Engineering recommends removing the leaning torrey pine P-56 (WCA) / Tree #5 (Rappoport) because it overcrowds the adjacent pines and is detrimental to their health (Attachment 4). Staff requests Council provide direction on removing tree P-56.

As part of staff’s presentation to the City Council, project estimates and individual tasks costs will be provided. Overall, it is staff’s opinion that an additional $600,000 or more will be needed to complete the project as outlined above. Costs for remediation of the soil below the base material are anticipated at another $150,000 or more.

FISCAL IMPACT:

There is no significant fiscal impact associated with advertising the project(s) for bid. This project was added during the FY 20-21 Capital Improvement Program midyear adjustment process with an allocation of $800,000 (400700000-98090-21003). To date, a total of $110,200 has been expended for design, leaving a balance of $689,800 for construction. Requests for additional appropriations will be included during award of each of the contracts for construction.

ALTERNATIVE:

The Council could choose not to authorize staff to advertise the project for bid and return with additional options/information.

CALIFORNIA ENVIRONMENTAL QUALITY ACT:

The project is categorically exempt from the provisions of CEQA based on Article 19, Sections 15301 (existing facilities), 15302 (replacement or reconstruction), and 15304 (minor alterations to land).

Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com 1 BACKGROUND AND ASSIGNMENT
In September of 2020, West Coast Arborists, Inc. (WCA) was contacted by the City of Coronado regarding the assessment of one Torrey pine (Pinus torreyana) and two Canary Island pines (Pinus canariensis) trees located on the northwest side of the Coronado lawn bowling club. In Arbor Access (WCA's tree inventory database), the trees are inventoried as 2 X SPRECKELS PARK WEST PLAZA P-55, 601 D AV F-10, and 601 D AV F-11. For this report, the trees will be referred to as Tree P-55, Tree F-10, and Tree F-11. The site map below identifies the location of these three subject trees with this icon " ", and six other surrounding trees with this icon " ".

The City had concerns regarding fungal fruiting bodies that were creating lumps within the artificial lawn bowling turf. The City requested that WCA assess the situation and provide management recommendations from an arboricultural perspective1, specifically regarding the three subject pine trees (P-55, F-10, & F-11) being considered for removal to mitigate these turf problems.
1 The City had already acquired a pathology report from Rutgers University as well as a report from PACE Turf LLC. Both of these reports were provided to WCA to review.

Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com 2 OBSERVATIONS
The subject trees and site were inspected on September 30, 2020. On-site, the health and structure of the trees was assessed in accordance with the ISA Best Management Practices (BMPs)2. The inspection of defects within the crowns was limited to a ground-level visual inspection, below ground parts such as roots was limited by soil, hardscaping, artificial turf, and photos within a PACE Turf, LLC report from 9/23/2020 when some turf was cut open. On-site and within the two provided reports, the following relevant observations were noted:

Refer to Photos in Appendix A
General Site & Report Observations
• The trees were located on the northwest side of the Coronado lawn bowling club and surrounded by irrigated turf grass.
• Judging by the color and density of foliage, the trees were in fair-good health for the species and time of year. The trees also exhibited generally good structure having a dominant central leader with subordinate branching.
• There were various other trees in close proximity to the lawn bowling area, including a young magnolia (F-4) to the south and several other pines to the north. There was also a privet hedge (Ligustrum spp.) adjacent to the lawn bowling area to the northwest. • There was a plastic root barrier between the privet hedge and the lawn bowling area. • There were several noticeable bumps and depressions on the northwest side of the artificial lawn bowling turf as well as repairs and holes from fungicide injections. These bumps ranged between 35 and 60 feet from the subject trees.
• There were numerous fungal fruiting bodies growing in the same planting area as the privet hedge. The mushroom species appeared to match the tentative identification of the dyemaker's puffball from the pathology report.
2 Terms appearing in boldface type are defined in the Glossary at the end of this report.

Attachment 1
City of Coronado Page 973
Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com 3 • The pathology report from Rutgers University tentatively identified the fungus as a dyemaker's puffball (Pisolithus tinctorius). It also stated that these mushrooms "are quite capable of producing enough turgor pressure to force their way through asphalt and other hard surfaces.

These fungi usually grow in decaying organic matter, such as buried tree stumps, tree roots, or even buried construction lumber, and some live symbiotically with the roots of living trees.

They will eventually disappear after the organic matter food source is exhausted, however, it can take up to ten years for a large stump or root to decay. Be aware that the fungus can also thrive in sand, asphalt, gravel, or other poor soil conditions which have little or no organic content. It is difficult to totally eradicate puffballs from the landscape. The only adequate control would be to dig up and destroy the underground sources of organic debris, but we have little faith in this approach."
• PACE Turf, LLC's report differed slightly from Rutgers University's pathology report, saying that "effectiveness of the repair is unknown as long as conifer roots are present under the green." The report offered a recommendation of removing all trees and the privet hedge from the surrounding area as well as any existing roots under the green before it is rebuilt. The report had an image of a small root that was said to be a likely source of nutrition for the fungus. This root appeared to be dead, decaying, and was not identified as belonging to a conifer. The report also stated that "effectiveness of fungicides or other chemical barriers to growth of the fungus is unknown."
Tree Specific Observations
• Tree P-55 had a height of about 90 feet and had a trunk diameter of 42 inches. The tree had a slight lean towards the northwest, likely in response to sunlight. The tree was quite mature and appeared to have multiple bird nests in the upper canopy (likely egrets or herons). The tree's trunk was about 12 feet northeast of the bowling area's concrete footing and about 60 feet from the nearest bump/ repair in the artificial turf.
• Tree F-10 had a height of about 60 feet and a trunk diameter of 27 inches. The tree was growing within a parkway about 35 feet from the nearest bump in the artificial turf. • Tree F-11 had a height of about 60 feet and a trunk diameter of 24 inches. The tree was growing within a parkway about 35 feet from the nearest bump in the artificial turf.

Species/Root Profiles
Pinus torreyana is a pine tree native to coastal San Diego and on Santa Rosa Island. Several sources say it is the rarest native pine tree in North America (possibly the world). It is a protected species in several areas of San Diego, but to my knowledge, it is not protected in Coronado; however, mature specimens may be eligible for protected heritage tree status. Aside from the few undisturbed native ecoregions in San Diego, it is commonly planted as an ornamental tree in our coastal and inland areas. When mature, this tree will often have a rounded or vase-shaped canopy. This tree is susceptible to several canker diseases and bark beetles, especially when stressed.

Pinus canariensis is a pine tree native to the Canary Islands but is commonly planted as an ornamental tree in San Diego. This tree species generally has no protected tree status in Coronado/San Diego. It often has a columnar or conical shape and is susceptible to canker diseases and bark beetles, especially when stressed.

Roots are an essential component of all trees and shrubs. They anchor and support their structure, absorb water and minerals, store carbohydrates, and produce hormones. The radius of a tree's root system is approximately equal to the height of the tree; however, the root systems will vary substantially with species, soil conditions, and surrounding history/environment. My general experience with these two species is that the roots are much more likely to grow outwards than downwards. This is especially the case in urban environments surrounded by irrigated turf. The root systems often grow laterally in the top 6 -18 inches of soil, where essential resources are most plentiful.

Appraisal Review - Trees provide numerous valuable benefits, including increased real estate values, conserving energy, removing atmospheric contaminants, moderating stormwater runoff, sequestering carbon, wildlife habitat, improving physical/ mental aspects of human health, and increasing social capital. An appraisal of the three subject trees was included in this report as seeing a dollar amount could be useful information when making final management decisions regarding tree removal or preservation decisions. Based on the Trunk Formula Method, the three subject trees were assessed as having a combined value of $186,800 (refer to Tree Appraisals in Appendix B). There were also five other valuable pines and a magnolia tree with a root-growing potential to reach the lawn bowling area (refer to Figure 1 Site Map).

Discussion of the Problem – The lumps in the artificial lawn bowling turf appear to be a nuisance with somewhat complicated solutions. These puffball fungi are known to form beneficial mycorrhizal associations with pine roots, so I understand the concerns and desires to remove the subject pines and all organic matter beneath the greens. However, Rutgers University said they have little faith in this approach working and that this fungi generally grows on decaying organic matter and is known to also thrive in sand/ gravel with little or no organic matter content. In addition, the root that was found in the lab sample appeared to be dead/ decaying and was not identified as being from a conifer. There Attachment 1
City of Coronado Page 975
Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com 5 seems to be a lack of evidence to show that removing the trees would considerably impact mitigating the conflicts between the artificial turf and the fungi.

Mitigation Strategies - Below is a list of five strategies to consider in helping mitigate the conflicts between the puffball fungi and the artificial lawn bowling turf:

1. Replace the artificial turf with natural turf. This may be the least expensive option up front, but water and maintenance expenses of living turf would need to be considered. This option would have minimal impacts on tree health and stability, reduce heat island effects, and maintaining healthy soils, should reduce the occurrence, and facilitate removal of puffball mushrooms.

2. Replace the gravel base material beneath the artificial turf with concrete. I have seen and heard of these mushrooms popping up through asphalt but the likelihood of it popping up through intact concrete seems quite unlikely. A drainage system would have to be implemented for this impermeable surface; however, looking at how fine and compacted the gravel beneath the turf was, there are likely already drainage improvements desired. Suspending the turf over thick interlocking drainage tiles may also be a valuable addition to improve drainage.

3. Remove all organic materials beneath the artificial turf, increase the depth of base material below, and install a 3-foot-deep concrete footing or plastic root barrier around the perimeter of the lawn bowling area. This approach would likely help mitigate the problem but considering that the fungi can grow in gravel without organic matter, there would be no guarantee. There is also the concern of impacting the health and stability of the trees, particularly P-55 due to its size and lean. The book ISA Best Management Practices for Root Management 2017 states that "linear root cuts on one side of a tree can reduce stability when the cut is made at a distance from the trunk that is less than three times the trunk diameter." It also says that "cutting roots at a distance greater than six times the trunk diameter (DSH) minimizes the likelihood of affecting both health and stability." If a linear root cut must be made, I recommend that it does not exceed the recommendations in the following chart:

Keep in mind that aside from removal, there is no way to guarantee that any tree will not fail.

These are recommendations based on research and industry best management practices to help tree managers make informed decisions on these assets. If concerns over potential hazards remain, I recommend having an ISA-qualified risk assessor perform a Level 2 assessment.

Attachment 1
City of Coronado Page 976
Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com 6 4. Remove all nine trees and woody plants (hedges) surrounding the perimeter of the lawn bowling area, remove all organic matter beneath the artificial turf, and increase the depth of base material below. This approach could also help mitigate the problems, but there doesn't appear to be a guarantee, and you would lose all of the benefits the trees provide. Suspending the turf over thick interlocking drainage tiles may also be a beneficial addition to improve drainage.

Tree Protection Plan – I also recommend establishing a formal tree protection plan before commencing any construction work to help mitigate impacts to tree health and stability. This is an additional service WCA can provide.

Bird Precautions – There were several large bird nests (likely egrets or herons) in the upper canopy of Tree P-55. There are numerous federal and state laws with serious consequences for protecting birds and their habitat. Collaborating with a wildlife biologist to identify the birds (if any) and review options before removing the tree or nests is recommended.

Replacement Trees – If trees are removed, I recommend that replacements are species that comply with the City's approved tree list(s). To make any specific recommendations, I would like to speak with the City to help ensure that a balance between the trees' needs and the goals of the community/city are being met. To help mitigate root conflicts, I would generally recommend larger trees in the open turf area (to northeast) and smaller trees in the parkways with restricted soil volume. Keep in mind that all trees have woody roots that could provide a growing medium for fungi.

Appraisal Methodology
The appraisal process used in this report is based on the methodology found in the 9th Edition Guide for Plant Appraisal. For regional-based information, the Species Classification and Group Assignment publication from the Western Chapter of the International Society of Arboriculture was also used.

There are multiple approaches to calculating a tree's value, and the Trunk Formula Method is the method that was used for the subject tree. This method is generally used to appraise the monetary value of trees considered too large to be directly replaced with nursery or field-grown stock.

Determination of the value of a tree is based on the cost of the largest commonly available transplantable tree and its cost of installation, plus the increase in value over time to grow to its current size. These values are adjusted according to the Species of the tree and its physical Condition, as well as the landscape Location (Site, Contribution, and Placement) (Council 70).

From: Dr. J. E. Adaskaveg, Professor
The mushroom in the photographic plate that was sent to me and that was identified as Pisolithus tintorius by scientists at Rutgers University is a common mycorrhizal fungus of pine (Pinus spp.) and oak (Quercus spp.) trees in California and the United States. The fungus forms a symbiotic relationship with the tree host and is beneficial to the tree in supplying micronutrients that the plant may not have access to while receiving plant produced carbohydrates. The fungus commonly forms a mushroom during adequate soil wetness and high nutrition from the tree typically occurring in late fall and winter in California. Publications concerning this fungus demonstrate that it can be cultured on standard microbiological media in the laboratory and therefore, it is not limited to a biotrophic relationship with roots of a host tree. Still, the fungus is thought to primarily exist in mycorrhizal relationships in nature.

A few reports have found the fungus producing a fruiting body (i.e., mushroom) in bare sandy soil, but this is not typical, and most reports document the fungus fruiting in association with a tree species.

Your premise that, ‘the fungus will not thrive on dead roots’ is most likely true. However, large tree roots may remain alive for months until carbohydrate supplies are diminished, with eventual root death.

The length of time of root survival after cutting the roots depends on the root size and the tree species.

In general, mushrooms form from larger roots that have adequate nutrition and during wet periods (from irrigation or rainfall). During the time period of roots dying, the fungus may try to produce fruiting bodies again in a survival response so it can disseminate itself as basidiospores that develop in the fruiting body.

The second part of your plan to excavate the soil to remove living roots and replace the soil with “clean” soil beneath the green is also sound to prevent a re-occurrence of this situation in a few years. If most of the surface roots under the bowling green are removed to a depth of one foot and there are no large roots present and a root barrier is installed to prevent new tree roots from regrowing into the new replacement soil, it is highly unlikely that the mushrooms of Pisolithus tintorius will develop under the new bowling green of artificial turf. To sever roots of pine or oak trees, a mechanical trencher (perhaps one used for installing irrigation systems) may have to be used to cut the roots to a depth of three to four feet (depending on the tree species and tree size) just within the dripline of the tree canopy. A root barrier can be installed in the trench to prevent re-growth of roots into the area under the bowling green.

Many people have personally complained about this fungus to me. The mushrooms of the fungus are capable of lifting up pavement in driveways or sidewalks. Root removal and installation of root barriers are the common practices used to prevent this from re-occurring.

RE: Arborist Report for Tree #5 at Coronado Lawn Bowling Site Dear Mr. Kump,
Per your request, the following is a brief summary of why I recommended removing tree #5:

1. Tree leans over the bowling green, tree roots expected to be beneath the bowling green.

2. Tree had a 35% live crown ration, (LCR). A measurement below 50% is a metric for poor health condition.

3. Tree had been previously topped, resulting in a 15% lean.

4. The tree was suppressing and deforming the crowns of surrounding trees.

5. The site is overcrowded with four large growing trees.

6. Removing the tree would provide improved sunlight, benefitting the health condition of the surrounding trees and removing a root source growing beneath the bowling green.

7. The removal recommendation is not due to the tree health or potential risk of failure. However, the tree lean, low live crown ratio, suppression of adjacent trees and proximity to the bowling green with roots are defects that create risk to the public and the future bowling green.

Please contact me with any questions or comments.

Sincerely,
Jeremy Rappoport

PUBLIC SCOPING COMMENTS FOR THE U.S. NAVY’S SUPPLEMENTAL ENVIRONMENTAL IMPACT STATEMENT FOR IMPROVING HOMEPORT FACILITIES FOR THREE NIMITZCLASS AIRCRAFT CARRIERS IN SUPPORT OF THE U.S. FLEET RECOMMENDATION:

Review the draft public scoping comment letter and provide direction.

BACKGROUND:

On June 9, 2023, the U.S. Department of the Navy (Navy) announced their intent to prepare a Supplemental Environmental Impact Statement (SEIS) for Improving Homeport Facilities for Three NIMITZ-Class Aircraft Carriers. The proposed project would allow three aircraft carriers to be in port simultaneously at Naval Air Station North Island (NASNI) for an average of 180 intermittent, non-consecutive days per year.

The Navy previously prepared an Environmental Impact Statement in 1999 to evaluate the potential environmental impacts of simultaneously homeporting three aircraft carriers at NASNI for 13 days per year. The Navy subsequently prepared a SEIS in 2008 to extend the duration that three aircraft carriers could be homeported at NASNI to 29 days per year. The current proposal would allow three aircraft carriers to be homeported at NASNI for at “an average of 180 intermittent, non-consecutive days of the year,” which could be interpreted as at least 180 days in a given year, and potentially longer depending on the meaning of that phrase.

The Navy held three public scoping meetings in June and is seeking public comments regarding the proposal through July 24, 2023. The purpose of the public scoping process is for members of the public and affected state and local agencies to identify any concerns with the project and to help define the areas of study to be included in the SEIS. The Navy has indicated that there will be additional public meetings and opportunities for public comment following release of the draft SEIS for public review, which is scheduled to occur in summer 2024.

ANALYSIS:

The Navy has indicated that the proposed extension from 29 days per year to “an average of 180 intermittent, non-consecutive days” per year is needed because (1) aircraft carrier capable berths at NASNI do not currently have the capability to support the Navy’s next generation aircraft carriers (FORD-Class), and (2) current mission objectives, which include operational, deployment, and maintenance schedules, may result in three aircraft carriers being in port at NASNI at the same time for more intermittent, non-consecutive days per year than previously analyzed. The presence of three aircraft carriers may include all three NASNI-homeported aircraft carriers or two NASNI-homeported aircraft carriers and one transient aircraft carrier. Transient FORD-Class aircraft carriers may berth at NASNI once deployed on the West Coast. The proposal does not include homeporting any additional aircraft carriers at NASNI.

City of Coronado Page 1008
Staff has prepared the attached draft public scoping comment letter to identify the issue areas that should be studied and included in the SEIS. In addition to requesting specific areas of analysis, the draft letter also requests the Navy clarify the project description to clearly describe the maximum number of days three aircraft carriers could be homeported, and if more than 180 days, to base the environmental analysis based on the maximum number of days to ensure an accurate evaluation and to develop effective mitigation measures. The letter also requests clarification on the proposed electrical power infrastructure project that is noted in the Navy’s public notice.

Staff has specific concerns about the project generating additional vehicle trips on City roadways and creating more frequent and intense periods of traffic congestion. The proposed comment letter therefore requests that the Navy perform a comprehensive traffic evaluation, including an analysis of the cumulative traffic impacts from past, present, and future planned projects, and that the Navy commit to implementing feasible and enforceable mitigation measures that result in measurable reductions in vehicle trips.

The draft letter also asks the Navy to consider changes to land use that have occurred since the 2008 SEIS, including construction and operation of Naval Base Coronado Coastal Campus, new on- and off-base development, and significant changes to the housing market and housing policies, including policy changes by the State of California and SANDAG to require local cities to produce more affordable housing and to provide housing opportunities for active-duty service members and civilian employees of federal military installations.

In addition to traffic and land use issues, the draft comment letter also requests the Navy evaluate air quality, climate change/greenhouse gas emissions, noise, infrastructure (including sewer and stormwater facilities), hazards and hazardous materials (including radiological elements), marine and surface water quality, biological resources, and population and housing.

FISCAL IMPACT:

None.

ALTERNATIVE:

The City Council may direct staff to modify the draft public scoping comment letter.

CALIFORNIA ENVIRONMENTAL QUALITY ACT:

This activity is not a project as defined by CEQA and is therefore exempt from environmental review.

PUBLIC NOTICE:

No notice required.

Subject: Public Scoping Comments for the Supplemental Environmental Impact Statement for Improving Homeport Facilities for Three NIMITZ-Class Aircraft Carriers in Support of the U.S. Pacific Fleet
Dear CVN SEIS Project Manager:

The City of Coronado (City) appreciates this opportunity to offer public scoping comments for the Supplemental Environmental Impact Statement (SEIS) for Improving Homeport Facilities for Three NIMITZ-Class Aircraft Carriers in Support of the U.S. Pacific Fleet. As the host city for Naval Air Station North Island (NASNI) and the proposed project, the proposal to extend the time that three NIMITZ-Class Aircraft Carriers can be simultaneously homeported is of significant interest to the City of Coronado and its residents.

It is our understanding that the proposed action would increase the amount of time three NIMITZClass Aircraft Carriers can be simultaneously homeported in Coronado from 29 days to an average of 180 intermittent, non-consecutive days per year. The City further understands that the Navy intends to analyze the project’s potential impacts to/from traffic, air quality, socioeconomics, environmental justice, biological resources, cultural resources, geology and soils, hazardous materials and waste, infrastructure, land use, noise, public health and safety, visual resources, and water resources.

The City appreciates the Navy’s intent to comprehensively evaluate the project’s impact on the local environment and offers the following comments to help define the scope of analysis included in the SEIS.

Project Description
The public notice for the proposed SEIS indicates that “…the Navy plans to analyze the impacts of an anticipated need for three aircraft carriers to be in port simultaneously for an average of 180 intermittent, non-consecutive days per year”. It is the City’s understanding that 180 days does not represent the maximum number of days that three aircraft carriers could be simultaneously homeported at NASNI, but rather, is a number that would be used to frame the scope of the environmental analysis. The City requests that the Navy clarify the meaning of “180 intermittent, City of Coronado Page 1010
CVN SEIS Project Manager
July 24, 2023

Page 2 ends

non-consecutive days per year” and indicate the maximum number of days that three carriers could be homeported at NASNI under the proposal. If the proposal would allow three aircraft carriers to be homeported for a duration longer than 180 days, the environmental analysis should be based on the maximum number of days to accurately evaluate potential environmental impacts and to develop adequate mitigation measures to avoid, minimize, or reduce those impacts.

The project description also refers to “proposed electrical power infrastructure”, but does not include any details about the scope or nature of this activity. Please provide additional information about this proposal, including its purpose, operating characteristics, location(s), and dimensions.

Depending on the scope and nature of this activity, additional environmental study and analysis may be required (e.g., cultural resources if excavation into native soils is required).

Transportation and Traffic
The SEIS should include a detailed and comprehensive technical evaluation of the existing onand off-base transportation infrastructure, traffic conditions, the project’s anticipated traffic generation, and its direct and cumulative impacts to traffic congestion and transportation infrastructure, including consideration of the project’s impacts when combined with other past, present, and future projects.

The traffic analysis should include an evaluation of the project’s impact on the levels of service (LOS) of City roadways and intersections, the San Diego-Coronado Bridge, State Routes 282 and 75, and assess the increase in vehicle miles traveled (VMT).

For each identified traffic impact, the SEIS should identify feasible, measurable, and legally enforceable mitigation measures with the goal of reducing vehicle trips, VMTs, and/or financing improvements to local transportation infrastructure. Specifically, the Navy should commit to 1) investing in viable alternatives to single-occupancy vehicle trips, such as restoring direct ferry service between downtown San Diego and NASNI, providing expanded and improved alternative transit options such as direct bus services to NASNI, commuter buses, and vanpool and carpool options; 2) providing financial incentives for active duty personnel and the civilian workforce to utilize alternative transportation options; 3) developing more on-base housing to reduce the number of commuters; and 4) coordinate with Caltrans, SANDAG, and the City of Coronado to finance and implement meaningful improvements to the local transportation network.

The SEIS should not rely on mitigation schemes that distribute vehicle trips to Coronado’s residential streets to minimize impacts to primary arterials and thereby avoid mitigation requirements. The SEIS should also not focus on implementation of staggered work hours that aim to reduce the intensity of traffic impacts at the expense of further extending the peak commute period and duration of traffic congestion. These types of mitigation measures, which may minimize the project’s impact on a roadway’s level of service during specific times of day, do not remove any vehicle trips and consequently should only be considered if complementary to measures which measurably reduce vehicle trips and/or VMTs.

The City also encourages the Navy to prioritize on-base operational and circulation changes that can effectively reduce vehicle trips, congestion, and off-base traffic impacts.

Land Use
The SEIS should evaluate changes to land use and the regulatory setting since the 2008 SEIS, including the construction and operation of the Coronado Naval Base Coastal Campus, and new development that has occurred both on-base and within the City of Coronado.

Additionally, the SEIS should consider significant changes to the housing market since 2008, including the State of California’s housing shortage, the rapid escalation of real estate costs and increasing lack of affordable housing options, and most importantly, recent policy changes by the State of California and SANDAG to require local cities to produce more affordable housing and to provide housing opportunities for active-duty service members and civilian employees of federal military installations.

The SEIS should identify the increased number of service members and the maximum duration that they are anticipated to be at NASNI and evaluate the impact the increased population may have on housing availability and demands for public services and facilities, including schools, medical facilities, police, fire protection, and parks and recreation facilities. The SEIS should also include appropriate mitigation and/or programs to minimize resultant impacts and the associated costs to the City of Coronado of providing housing and expanded public services and facilities.

Air Quality
The SEIS should evaluate the project’s impact on air quality resulting from increased emissions from automobiles and homeported vessels. The SEIS should assess the project’s compliance with the National Ambient Air Quality Standards (NAAQS), the California Ambient Air Quality Standards (CAAQS), and specifically evaluate ozone, volatile organic compounds, nitrogen oxides and nitrogen dioxide, carbon monoxide, sulfur dioxide, and particulate matter emissions and whether identified emissions would result in any air quality violations or contribute to any regional non-attainment of air quality standards.

Climate Change/Greenhouse Gas Emissions
The SEIS should analyze the increase in greenhouse gas (GHG) emissions resulting from increased automobile traffic and expanded operations of homeported vessels, including CO2, methane, nitrous oxides, hydrochlorofluorocarbons, hydrofluorocarbons, and ozone emissions. The SEIS should include adequate mitigation, such as measures to reduce VMTs, to ensure that post-project GHG emissions are equal to or less than the baseline condition.

Noise
The SEIS should consider the project’s generation of noise from increased automobile traffic and expanded operations of vessels homeported in Coronado. The SEIS should evaluate whether any new or increased noise would violate the City of Coronado’s Noise Ordinance or result in a significant impact to nearby sensitive receptors, including but not limited to, residential, education, elder care, or medical care uses.

Infrastructure
The SEIS should assess potential increases in sewer and stormwater flows resulting from the project and determine whether such increases would require any new or expanded facilities either on- or off-base. The SEIS should also examine past failures of the on-base sewage system and City of Coronado Page 1012

odor issues and propose mitigation measures to upgrade the system to prevent future failures and offensive odors from impacting nearby Coronado residents. The Navy’s existing chemical dosing program in the wastewater system for odor reduction is not pro-actively monitored/adjusted to account for changes in wastewater flows related to additional ships in port; this is an aspect that should be reviewed for improvement.

Hazards/Hazardous Materials
The SEIS should describe the types of hazardous materials anticipated to be involved with the project, including radiological elements, and evaluate potential adverse impacts from the production, use, storage, transport, and/or potential release of hazardous materials. The SEIS should also describe applicable regulations, programs, and policies that govern the use, storage, and transport of hazardous materials, emergency response plans and protocols for managing and remediating potential accidental releases of hazardous materials, and how the project would comply with applicable regulations.

Water Quality
The SEIS should consider potential impacts to marine water quality and surface water quality resulting from the proposed project, describe operational practices to avoid or minimize contamination of marine and surface waters, and outline any proposed mitigation measures and/or best management practices proposed to avoid significant environmental effects.

Biological Resources
The SEIS should include updated biological surveys and a new evaluation of the project’s potential impacts on marine life and their habitats, including but not limited to plankton, eelgrass, invertebrates, fish, birds, marine mammals, and sea turtles. The SEIS should identify any state or federally listed threatened or endangered species known to reside in the project vicinity and evaluate whether the proposed project may result in any direct or indirect impacts to those species.

If potential impacts are identified, the SEIS should detail proposed mitigation measures to avoid or minimize any adverse effects.

Re: Request to Support Tijuana Infrastructure Repairs in the Ocean Justice Strategy Dear Chair Mallory:

I have the great privilege of serving as the Mayor of the City of Coronado, California. On behalf of the City, I am writing to express concern about the severe, ongoing environmental justice and public health emergency in the San Diego region caused by failing wastewater infrastructure in Tijuana, Mexico.

The White House Council on Environmental Quality (“CEQ”) recently announced a request for comment on a proposed environmental justice strategy for the nation’s Oceans. (88 Fed. Reg. 37518 (June 8, 2023).) Specifically, CEQ has asked for comment on “[w]hat injustices related to the ocean should the Federal Government better address?” In response to your question, we ask that the Biden Administration make halting the environmental justice and public health emergency occurring in the Pacific Ocean in south San Diego County the Administration’s highest priority.

At its core, this is an issue of environmental justice. Contaminated water flows from Tijuana into the Pacific Ocean, causing severe health risks for individuals and families visiting beaches in southern San Diego County.1 Coronado’s beaches (along with those of neighboring Imperial Beach) provide the closest and most affordable ocean access for many of San Diego’s Disadvantaged Communities (“DACs”).

Indeed, large swaths of South San Diego, and portions of National City, Chula Vista and Imperial Beach qualify as DACs. Coronado and Imperial Beach are the closest beaches and provide the easiest access for these communities. Parking is free, and there is wide, open access to the shoreline. The ocean also provides a source of food for residents and visitors alike who harvest fish and shellfish from our beaches. This source of food can be invaluable for

1 Please see attached letter from Representatives Scott Peters, Juan Vargas, Mike Levin, Sara Jacobs and Daryl Issa to President Biden, requesting a Declaration of a State of Emergency for the Tijuana River Valley; and letter from Representatives Scott Peters, Juan Vargas, Mike Levin, Sara Jacobs to Baja California Governor, Marina del Pilar Avila, requesting interim measures to reduce cross border sewage flows.

those with fixed or limited incomes. So while Coronado itself is not a DAC, it is the beach for many DACs in the San Diego region.

Those beaches also provide the basis for an economy and jobs. According to a recent study by the San Diego Association of Governments (“SANDAG”) Coronado hosts almost 4500 jobs in the retail, food service and hotel/accommodation sectors.2 These are jobs for waiters, hotel clerks, maids and other service sector employees. Most of the employees live in San Diego, National City, Chula Vista and Imperial Beach – the same location of the above mentioned DACs.3 Their jobs are put at risk if the City’s beaches are consistently closed because there will be fewer visitors to utilize their services.

The City is dedicated to maintaining clean beaches and a healthy environment, which is why we have consistently worked with our Congressional Representatives and the United States Environmental Protection Agency (“EPA”) to advocate for greater federal funding and faster implementation of solutions.

To their credit, through bi-partisan efforts, our Congressional delegation was able to mandate $300 million in funding to support new infrastructure in the Tijuana River Valley as part of the United States-Mexico-Canada Agreement (“USMCA”). Mexico subsequently committed $140 million for infrastructure improvements on its side of the border.

EPA has worked diligently with the International Boundary Water Commission (“IBWC”) to fund a series of projects that should ultimately solve the problem in what we are being told is 2027 or 2028. The City greatly appreciates EPA’s efforts and values the time and energy the agency has spent working on this issue. However, nothing is being done to stem the flow of sewage in the interim. Worse, we recently learned that there is an immediate deficit of $150 million in project funding caused by deferred maintenance on the International Wastewater Treatment Plant in the Tijuana River Valley (the “ITP”).4 We also recently learned that the proposed budget for IBWC in FY 24 is $6 million less than FY 23, and worse, it is $13 million less for construction of new projects. This is untenable given the backlog of maintenance costs faced by the agency and the need for new projects to address cross border pollution.

This is a problem that is multi-agency and bi-national in nature and that is in need of White House engagement and leadership. The Biden Administration can take several actions today, that would help alleviate this situation:
 Request from Congress and/or allocate from existing programs, all funds necessary to construct, operate and maintain all projects necessary to stop sewage flowing north from Mexico.
 Ensure that EPA’s planned infrastructure in the Tijuana River Valley is constructed on the fastest possible timeline, and make this the Administration’s top environmental priority.

 Direct EPA and IBWC to develop and implement interim solutions to reduce sewage flows between now and the date of completion of the main projects.  Ensure that EPA and the IBWC are fully funded and have the staff necessary to implement all projects on the fastest possible timeline.  Ensure that the budget requests for IBWC and EPA include all costs related to operations, management and maintenance of existing and future infrastructure, including in situations where IBWC is relying on an outside vendor for operations and management.
 Engage with Mexico’s government at the state and federal level to ensure they are maintaining infrastructure in Mexico; to verify the financial commitment and timeline for reconstructing the San Antonio de las Buenas treatment plant in Mexico; and to ensure that the plant is completed on schedule.

Implementing these measures will help alleviate the crisis facing the South San Diego communities. The City of Coronado thanks you for leading the Ocean Justice Strategy for a healthier ocean environment. We look forward to continuing to work with you and your staff on these important initiatives.

Sincerely,
Richard Bailey

The Honorable Joseph R. Biden, Jr.

President of the United States of America
The White House
1600 Pennsylvania Avenue NW
Washington, D.C. 20500
Dear President Biden:

We strongly urge you to declare a Federal State of Emergency for the Tijuana River Valley. The influx of sewage, trash, and industrial waste from the Tijuana River – flowing across the U.S.-Mexico border and into San Diego County – have contributed to some of the most polluted beach areas in the country. The surge in toxic pollution has severely impacted San Diego County’s economy and environment and is a serious health hazard for the Navy sailors who train in our waters.

The Tijuana River has remained one of the most pressing environmental issues in our region. Despite a decadeslong discussion, more progress has yet to be made to permanently address these ongoing problems. Our communities have faced the brunt of the Tijuana River’s ecological effects. In 2017, the Environmental Protection Agency attributed over 34,000 illnesses to water quality pollution. Researchers continue to monitor its heightening impact on local air quality, coastal water pollution, and levels of chemicals and pathogens.

Due to these health concerns, the Cities of San Diego and Imperial Beach have maintained an ongoing State of Local Emergency. These local emergencies accompany the County of San Diego’s Public Health Crisis declaration. Unfortunately, the resources of our state and local governments have not sufficiently protected impacted communities. And while we are proud to have secured $300 million for the International Boundary and Water Commission via the Environmental Protection Agency in the United States-Mexico-Canada Agreement and the FY23 Appropriations bill, we know that more is required for a long-term solution to this crisis. We respectfully request a Federal Emergency Declaration to create a multi-agency response to address this matter and open avenues for additional federal funding. This isn’t simply a request, but a necessity.

The ongoing disaster of the Tijuana River warrants the same federal resources and attention as any other natural and environmental disaster. Left unaddressed, a pollution crisis of this scale will continue to wreak havoc on our region. We cannot afford to wait months, or even years, as the environmental and economic integrity of the Tijuana River Valley fades away. Enclosed is a letter the Mayor of Imperial Beach sent to the White House Council of Environmental Quality echoing the need for a Federal Emergency declaration.

As the delegation representing the San Diego region, we strongly urge you to continue uplifting your commitments to support environmental justice communities and take action to address the ongoing crisis in the Tijuana River.

Dear Governor del Pilar Avila:

We write to thank you and the Mexican federal government for the $144-million commitment to sanitation infrastructure projects in Tijuana, Baja California as outlined in IBWC Minute No. 328. This investment will make a critical dent in the wastewater pollution currently plaguing the Tijuana River and River Valley, as well as the beaches in the border region. This wastewater pollution is badly hurting the communities we represent, and they are counting on the cooperation of our two governments to fix this environmental catastrophe.

To that end, we’d like to open lines of communication between our offices so we may be kept informed of the status of the Mexico-side projects. Our constituents are clamoring for an end to this crisis, and while we know that these investments will take some time to deploy, we respectfully request that your office keep us apprised of the progress being made so we can further assure the people of Imperial Beach, Coronado, and San Diego that relief is on the way. Specifically, we would like to know when you plan to break ground on a new treatment facility at San Antonio de los Buenos (SAB).

Currently, San Diego County beaches, particularly in the cities of Imperial Beach and Coronado, are closed and have been closed for years due to the untreated wastewater flowing into the Pacific Ocean from Punta Bandera and the Tijuana River. These beach closures are devastating to these communities which rely heavily on beach tourism to support their local economies. While we recognize that you are working hard to get a new plant built at SAB, we ask you to consider some immediate, short-term measures that might reduce the bacteria levels at our beaches.

The people we represent in San Diego County, particularly in Imperial Beach and Coronado, are extremely frustrated about their beaches being closed due to health hazards associated with untreated wastewater flowing up the coast. It has been suggested to us that, in the near term, dredging the existing settling ponds at SAB and adding chemical treatment and aerators could reduce bacterial levels enough to reduce our beach closure days. Is your government considering pursuing these approaches? At the same time, we will continue to push our U.S. federal agencies to pursue upgrades for the International Treatment Plant underway as quickly as possible. This is an urgent priority for all of us.

RE: Board Item #16: Proclamation of a Local Emergency for U.S.-Mexico Transboundary Pollution Environmental Crisis and Request for Federal State of Emergency
Dear Chair Vargas and Members of the Board of Supervisors:

As a community directly impacted by cross-border pollution and one that provides vital access to the ocean for over 3 million area residents and visitors each year, the City of Coronado supports actions and advocacy that will bring water quality solutions to the region as quickly as possible.

The EPA and IBWC’s comprehensive suite of infrastructure projects is encouraging, as is the funding appropriated by the Federal and Mexican governments. However, the funding is not enough—hundreds of millions more are necessary for complete implementation and operation of the pollution mitigation projects. Certainty of full funding is critical for streamlined construction and rapid implementation to prevent future pollution to the ocean environment.

Coronado joins the County in asserting urgency to bring additional resources to the region. Coronado supports and urges adoption of the County Proclamation of a Local Emergency for Transboundary Pollution Environmental Crisis, and request for official Federal Declaration of Emergency.

Thank you for your consideration of this crucial regional issue.

Sincerely,
Richard Bailey, Mayor
City of Coronado
