Re: Formal Submission—Opposition to Proposed Amendment to SLOMC Title 17, §17.02.020
(“Applicability” Subsection); Case No. CODE-0666-2025
Dear Chair and Commissioners:
On behalf of community stakeholders and interested residents, we respectfully submit the enclosed Legal
Research Report and supporting materials regarding the City’s proposed amendment to San Luis Obispo
Municipal Code (SLOMC) Title 17, §17.02.020 to add an “Applicability” subsection (the “Amendment”), noticed
under Case No. CODE-0666-2025.
Requested Commission Actions
1. Decline reliance on CEQA Guidelines §15061(b)(3) (“common-sense” exemption) for this citywide zoning
text change;
2. Direct preparation of a CEQA Initial Study (or, if the City prefers a policy-level action, a Program-level
CEQA document) addressing reasonably foreseeable environmental effects, including:
o Sensitive human receptors (children, seniors, and individuals with preexisting health conditions);
o Air quality/TAC and health risk, noise/vibration, lighting/ALAN, traffic micro-scale emissions; and
o Biological resources (habitat, nesting birds, wildlife movement), plus cumulative effects in
neighborhoods experiencing repeated right-of-way interventions; and
3. If the Commission elects to advance ordinance language, condition any recommendation on
incorporation of binding, ordinance-embedded environmental performance standards (CEQA non-
circumvention, receptor screening within 1,000 ft, clean construction equipment and work-window
controls, lighting design limits, biological timing/buffers, alternatives-and-findings, and cumulative
screening).
Basis for Submission (Executive Summary)
The Amendment alters the legal framework governing implementation of public “safety features” in the right -of-
way and at the parcel/ROW interface (e.g., curb extensions, medians, beacons, lighting, restriping). These
changes foreseeably induce physical effects and therefore constitute a CEQA “project.” On the present record,
the stringent standard for §15061(b)(3)—that it can be seen with certainty that there is no possibility of significant
environmental effect—is not met. Absent enforceable safeguards, foreseeable pathways include construction
emissions and toxic air contaminants, localized pollutant concentration shifts, noise/vibration, lighting spill and
circadian disruption, and vegetation removal/fragmentation affecting sensitive receptors and sensitive biological
resources.

Subject: Submission of Legal Research Report and Comment Letter Opposing Proposed Amendment to
SLOMC §17.02.020 (“Applicability” Subsection), Case No. CODE-0666-2025
Purpose of Transmittal
This memorandum formally transmits for inclusion in the administrative record the following materials opposing
the proposed amendment to Title 17, §17.02.020 of the San Luis Obispo Municipal Code (the “Amendment”)
noticed under Case No. CODE-0666-2025. The submittal addresses the Amendment’s legal foundation, internal
consistency with existing zoning regulations, and its foreseeable implications for sensitive receptors (children,
seniors, individuals with preexisting health conditions) and sensitive biological resources, consistent with the
analytical framework required by the California Environmental Quality Act (CEQA).
Materials Transmitted (Enclosures)
1. Legal Research Report (1) — Analysis concluding the Amendment is a CEQA project and that reliance
on CEQA Guidelines §15061(b)(3) (“common-sense” exemption) is unsupported given reasonably
foreseeable environmental effects, particularly to sensitive receptors and biological resources.
2. Legal Research Report (2) — Analysis Opposing the Proposed Amendment to Section 17.02.020 of
Title 17 of the San Luis Obispo Municipal Code
Page 3.
Summary of Key Points
• CEQA Applicability: The Amendment modifies legal discretion governing physical ROW interventions
(e.g., curb extensions, medians, lighting, beacons). Under UMMP v. City of San Diego (2019), such
zoning text changes constitute a CEQA project where indirect physical changes are reasonably
foreseeable.
• Exemption Unsupportable: The record does not demonstrate with certainty “no possibility of significant
effect” as required by §15061(b)(3). Foreseeable pathways include localized pollutant exposure to
sensitive receptors, construction emissions/noise, lighting impacts, and biological resource disturbance—
topics identified in CEQA Appendix G and §15065.
• Regulatory Consistency: Without embedded environmental performance criteria and clear cross-
references (e.g., encroachment permits, APCD thresholds, biological surveys), the Amendment risks
inconsistency with Title 17’s purpose and established review pathways at the parcel/ROW interface.
• Recommended Remedy: Rescind reliance on §15061(b)(3); direct preparation of an Initial Study (or
Program-level CEQA document) and adopt enforceable standards within the ordinance.
Requested Commission Actions
1. Direct Staff to Prepare CEQA Documentation: At minimum, an Initial Study addressing air quality/TAC
and health risk, noise/vibration, lighting, traffic micro-scale emissions, biological resources, and
cumulative effects in over-burdened neighborhoods (using SLO APCD screening/HRA protocols).
2. Decline the §15061(b)(3) Finding: Recognize the citywide scope and foreseeable receptor/resource
effects preclude the common-sense exemption on this record.
3. Condition Any Recommendation on Protective Text: If the Commission elects to forward an
ordinance, condition the recommendation on inclusion of the ordinance-embedded environmental
performance standards provided in Appendix C, including a CEQA non-circumvention clause, 1,000-ft
receptor screening, construction equipment standards (Tier 4 or verified after-treatment), lighting
specifications (≤3000 K, full cutoff, curfews), biological timing/buffers, and a findings/alternatives
requirement where conflicts arise.
Delivery and Filing Instructions
• Record Request: Please confirm receipt and inclusion of all enclosures in the administrative record for
Case No. CODE-0666-2025, and provide notice of any continuances or City Council hearings.

Brown Act and Public Records Act; all attachments may be shared with interested parties.
Legal Research Report (1) Opposing the Proposed Amendment to SLOMC §17.02.020 (Case No. CODE-
0666-2025)
Executive Summary
The proposed amendment would add an “Applicability” subsection to §17.02.020 of Title 17 (Zoning Regulations)
to “clarify how the Zoning Regulations apply” and to “clarify that the city may incorporate necessary public-safety
features” as part of public projects, noticed citywide under Case No. CODE-0666-2025 and designated CEQA-
exempt under the common-sense exemption (§15061(b)(3)).
This report concludes that:
1. The amendment is a CEQA “project” and may not be exempt under §15061(b)(3) because it has
reasonably foreseeable indirect physical effects—notably in the public right-of-way and at the
parcel/ROW interface—that can affect sensitive receptors (children, seniors, medically vulnerable
populations) and sensitive biological resources, thereby triggering formal CEQA review.
Page 4.
2. The draft approach risks inconsistency with the stated purpose of Title 17 and with existing procedural
and environmental review pathways, creating ambiguity around when zoning standards yield to “public-
safety features,” and how such features are analyzed and mitigated.
3. The record must include a robust analysis of sensitive receptors consistent with Appendix G and local air
district guidance before any categorical or common-sense exemption could be credibly invoked.
I. Background and Textual Posture
• Affected provision: Title 17, §17.02.020 (“Purpose and Authority”). The current codification articulates the
purpose of the Zoning Regulations but lacks a stand-alone “Applicability” subsection that delineates
exactly how/where Title 17 applies (especially for City-initiated work in the right-of-way).
• Proposed action: Planning Commission review of amendments to add an Applicability subsection; City’s
notice states the project is exempt under CEQA Guidelines §15061(b)(3) (“general rule”) and is citywide
in scope.
II. Legal Foundation and CEQA Framework
A. The amendment is a CEQA “project” as a matter of law
The California Supreme Court held that enactment and amendment of zoning ordinances are “projects” under
CEQA whenever they may cause direct or reasonably foreseeable indirect physical changes. Union of Medical
Marijuana Patients v. City of San Diego (“UMMP”), 7 Cal.5th 1171 (2019).
The amendment alters the legal regime governing where and how zoning regulations apply, including explicit
authorization for public-safety features in public projects. That legal change can foreseeably induce physical
changes (e.g., curb extensions, lane reconfigurations, lighting additions, median refuges, sight-distance
daylighting, barrier installations) within right-of-way and frontage areas—which brings it squarely within CEQA’s
definition of a project (§15378).
B. The “common-sense” exemption (§15061(b)(3)) is inapplicable on this record
The §15061(b)(3) exemption applies only where it can be seen with certainty that the activity has no possibility
of significant environmental effects. That is a demanding standard. Given the amendment’s citywide scope and
its operative purpose—to empower or clarify the City’s ability to implement public-safety features—there is at
least a reasonable possibility of effects (air quality “hot spots,” noise/vibration, lighting, vegetation change, habitat
fragmentation, construction emissions) especially near sensitive receptors and sensitive biological resources.
Accordingly, reliance on §15061(b)(3) is legally vulnerable. See also the Supreme Court’s treatment of
exemptions and exceptions in Berkeley Hillside Preservation v. City of Berkeley, 60 Cal.4th 1086 (2015).
C. Threshold CEQA authorities that constrain exemption use
• UMMP (2019): Zoning enactments/amendments are projects where they may induce physical changes;
a bright-line “no CEQA for zoning text” rule is rejected.
• Berkeley Hillside (2015): Even categorical exemptions are defeated by “unusual circumstances” where
there is a reasonable possibility of significant effects; by parity of reasoning, §15061(b)(3) cannot be used
where potential effects exist.
• Appendix G & §15065: Mandate findings and checklist inquiries for sensitive receptors (air toxics,
localized emissions) and biological resources; these cannot be bypassed by conclusory exemption
labels.
III. Potential Inconsistencies with Title 17 and Related Regulatory Architecture
1. Purpose vs. Effect: §17.02.020’s current purpose clause commits the City to orderly development,
environmental quality, and public health/safety via zoning. A new Applicability clause that functionally
insulates certain City right-of-way interventions from zoning-based scrutiny risks undermining Title 17’s
stated balance and circumventing established entitlement and review pathways for frontage/off -site
improvements that directly affect adjacent parcels and receptors.
Page 5.
2. Article 1 Structure: Title 17 already organizes enactment, applicability, and enforcement at the article
level. Inserting a broad, citywide “applicability” text focused on City projects—without cross-references to
discretionary review, public works standards, encroachment permits, and CEQA—may conflict with
existing sections that presume parcel-based application and discretionary findings.
3. Discretion Expansion Without Standards: Authorizing “public-safety features” without codified
performance criteria or thresholds (e.g., warrants, impact screens, receptor setbacks, lighting spill limits,
construction emissions protocols) injects unbounded discretion. Under CEQA, greater discretion
increases the duty to analyze and mitigate potential impacts before adoption; using §15061(b)(3) in the
face of expanded discretion is especially fraught.
4. General Plan/Program Consistency: Citywide authorization language could be read to privilege ROW
safety implementations over parcel-level development standards, without demonstrating General Plan
consistency or alignment with adopted air quality, biological, complete streets, and noise policies. That
hierarchy shift warrants a program-level CEQA review, not a common-sense exemption. (UMMP
emphasizes analyzing reasonably foreseeable indirect effects of planning/zoning actions.)
IV. CEQA Risks Centered on Sensitive Receptors (Human Populations)
A. Definitions and regulatory expectations
• Appendix G explicitly asks whether a project would “expose sensitive receptors to substantial pollutant
concentrations.”
• CARB & local air districts define sensitive receptors to include children, the elderly, and people with
preexisting conditions, and identify receptor locations (schools, daycares, hospitals, nursing homes,
residences).
• SLO County APCD CEQA Handbook (2021–2023 updates) requires receptor-focused screening and
Health Risk Assessment (HRA) where TAC/DPM or construction emissions may affect nearby receptors
(often within 1,000 ft).
B. Foreseeable impact pathways triggered by the amendment
By normalizing citywide deployment of ROW “public-safety features” without an ex ante CEQA framework, the
amendment enables patterns of activity that foreseeably:
• Concentrate construction emissions (diesel particulate matter, fugitive dust), noise, and vibration adjacent
to schools, daycares, senior housing, clinics, and residences. CEQA requires early identification and
mitigation (e.g., Tier 4 equipment, idling limits, dust suppression, schedules avoiding school hours).
• Alter traffic circulation in ways that shift idling/queuing or braking/acceleration closer to receptors (e.g.,
lane diets with new stop control, curb extensions, refuge islands), implicating localized pollutant
concentrations (Appendix G) and potential CO/TAC micro-scale hot spots.
• Introduce new lighting or audible devices (warning beacons) affecting sleep and stress for vulnerable
populations if not engineered with spill, glare, and timing controls—issues typically tested in project-level
CEQA.
Given these pathways, it cannot “be seen with certainty” that no significant effect is possible; thus §15061(b)(3)
is not supportable.
V. CEQA Risks for Wildlife and Sensitive Biological Resources
A. Legal triggers
• Mandatory Findings of Significance (§15065): Significant effects are presumed where there is potential
to reduce habitat, reduce populations below self-sustaining levels, or restrict the range of
endangered/rare/threatened species—conditions CEQA compels agencies to evaluate before adoption.
• Appendix G (Biological Resources): Requires analysis of special-status species, riparian habitat,
sensitive natural communities, and wildlife movement.
B. Mechanisms by which ROW features can affect biological resources
• Vegetation removal and regularized maintenance for visibility & sight distance (daylighting) can fragment
urban habitat patches, reduce nesting substrate, and alter edge conditions.
• Lighting upgrades (LED retrofits, pedestrian beacons) can increase artificial light at night (ALAN),
disrupting avian, bat, and insect behaviors; mitigation is design-dependent and site-specific (spectrum,
shielding, curfews).
Page 6.
• Physical barriers/median work may impede wildlife movement in peri-urban corridors, with cumulative
effects.
• Construction windows can overlap with nesting seasons absent enforceable timing constraints.
Because these are reasonably foreseeable outcomes of the very actions the amendment is designed to facilitate,
a programmatic Initial Study/EIR is the proper vehicle—not a blanket §15061(b)(3) finding.
VI. Procedural Adequacy and Record Support
The public notice asserts a §15061(b)(3) exemption for a citywide zoning text change. The record, however,
lacks a checklist-level demonstration that no significant effect is possible for any foreseeable implementation
case—inconsistent with CEQA’s requirement to substantiate exemptions with evidence tied to known thresholds
(e.g., SLO APCD screening, receptor proximity screens, biological resource flags).
UMMP emphasizes that agencies must not conflate “policy-level” text with “no physical effect.” Where text
changes the scope of discretion under which physical works occur, CEQA review is required.
VII. Recommended Legal Position and Remedies
A. Primary argument (Merits)
1. Project determination: The amendment is a CEQA project (UMMP).
2. Exemption rejection: §15061(b)(3) is inapplicable because potential effects on sensitive receptors and
biological resources are reasonably foreseeable from the amendment’s operative effect.
3. Evidence gap: The notice lacks substantial evidence showing no possible effect citywide; Appendix G
and local APCD guidance require receptor- and threshold-based analysis before adoption.
B. Procedural relief
• Set aside the exemption determination and prepare an Initial Study addressing air quality/TAC, noise,
lighting, traffic micro-scale, and biological resources with emphasis on sensitive receptors and sensitive
natural communities. Use SLO APCD screening tools and HRA triggers (e.g., 1,000-ft receptor screen).
• If policy-level adoption is preferred, proceed with a Program EIR (or at minimum a Negative/Mitigated
Negative Declaration with enforceable mitigation measures), establishing performance standards to be
applied at the project tier.
C. Substantive drafting fixes (if the City proceeds)
1. Non-circumvention clause: State that the Applicability subsection does not exempt City capital or ROW
projects from CEQA or from Title 17 where parcel-adjacent design affects private property or public
health/environment.
2. Sensitive receptor safeguards: Require pre-implementation screening (SLO APCD) and HRA where
receptors are within 1,000 ft; codify construction BMPs, equipment tiers, scheduling around school hours,
and post-implementation monitoring.
3. Biological resource protections: Incorporate nesting-season timing, lighting design standards (shielding,
spectrum ≤3000K, curfews), vegetation/habitat retention targets, and wildlife connectivity checks where
ROW intersects mapped sensitive communities. (Standards anchored to Appendix G and §15065
triggers.)
4. Conflict-resolution hierarchy: Where a “public-safety feature” conflicts with a Title 17 development
standard or adopted environmental threshold, require a written finding that the safety objective cannot
be achieved by less-impactful alternatives, with mitigation imposed to reduce receptor exposure to below
thresholds (air/noise/lighting).
5. Cumulative safeguards: Acknowledge that repeated ROW interventions can create cumulative local-
scale burden on certain neighborhoods; require cumulative screening in overburdened areas consistent
with air district guidance.
VIII. Broader Policy Implications if Adopted Without CEQA Review
• Equity and health: Vulnerable groups (children, seniors, those with respiratory/cardiac conditions) face
disproportionate risk from localized emissions and noise. CARB and regional guidance emphasize
proximity-based risk at schools, daycares, senior facilities, and residences—common along arterial
frontages where safety retrofits occur.
Page 7.
• Precedent risk: Normalizing §15061(b)(3) for citywide zoning text that enables physical works invites
future litigation under UMMP and Berkeley Hillside lines.
• Natural systems: Urban wildlife and sensitive communities within/adjacent to ROWs are incrementally
affected by lighting, vegetation removal, and barriers; §15065 requires a conservative approach where
sensitive species or habitats could be affected.
IX. Conclusion
Because the amendment alters legal discretion over physical interventions in the public realm and carries
reasonably foreseeable pathways to environmental effects—especially for sensitive human receptors and
sensitive biological resources—it is a CEQA project for which a common-sense exemption is unavailable. The
City should withdraw the §15061(b)(3) determination, conduct at least an Initial Study using Appendix G and
SLO APCD methodologies (with receptor- and habitat-focused analysis), and, if proceeding, adopt binding
performance standards and mitigations within the ordinance text.
Legal Research Report (2) Opposing the Proposed Amendment to Section 17.02.020 of Title 17 of the
San Luis Obispo Municipal Code
Executive Summary
This report presents a rigorous opposition to the proposed amendment under Case No. CODE-0666-2025, which
seeks to add an "Applicability" subsection to Section 17.02.020 of the San Luis Obispo Zoning Regulations. The
amendment would broadly exempt the City from its own zoning requirements for "public safety features"
associated with projects deemed necessary for public health, safety, and welfare. While the City claims this
facilitates efficient implementation of safety measures, such as netting on parking structures or generators near
fire stations, the proposal raises significant legal, regulatory, and environmental concerns.
Key arguments include: (1) the amendment's questionable legal foundation under California municipal law, which
generally requires cities to adhere to their own zoning ordinances absent specific statutory authority for blanket
exemptions; (2) potential inconsistencies with existing provisions in Title 17 and the City's General Plan,
undermining the framework for orderly land use; and (3) broader implications for sensitive receptors,
encompassing vulnerable human populations (e.g., children, seniors, and those with health conditions) and
wildlife species, as exempted features could introduce unmitigated environmental impacts in violation of the
California Environmental Quality Act (CEQA).
CEQA mandates early identification, thorough assessment, and effective mitigation of risks to these groups, and
the amendment's reliance on a "common sense" exemption under CEQA Guidelines Section 15061(b)(3)
appears untenable given the potential for significant effects. This report draws on statutory analysis, case law,
and environmental studies to substantiate these objections, recommending rejection or substantial revision to
ensure compliance and protection of community interests.
Background on the Proposed Amendment
As detailed in the City's staff report dated September 24, 2025, the amendment introduces Subsection C to
Section 17.02.020, clarifying that zoning regulations apply to all properties within city limits, including private,
City-owned, and other governmental lands, unless exempted by state or federal law. However, it carves out a
specific exemption for the City itself regarding "public safety features," defined expansively as "structures,
architectural elements, devices, barriers, technology, communications, operational resiliency, fencing and/or
walls, or other features of a public project that protect the public health, safety and welfare of the community."
The rationale, as per the report, addresses practical challenges in City projects, such as installing safety netting
exceeding height limits under Section 17.70.080(C)(2) or placing generators within setbacks required by Section
17.70.170(C)(6). The Planning Commission Resolution No. XXXX-25 recommends adoption, citing consistency
with General Plan Land Use Element Policies 12.1 and Programs 4.9, 4.23, and 4.36, and claiming CEQA
exemption under Section 15061(b)(3). Public notices were issued, with a hearing on September 24, 2025.
Page 8.
Despite these assertions, the amendment's broad scope invites scrutiny, as it could enable unchecked
modifications with environmental repercussions, bypassing standard reviews.
Analysis of the Amendment's Legal Foundation
California municipal law vests cities with authority to enact zoning ordinances under Government Code Section
65800 et seq., but this power is not unbounded. Critically, cities are generally required to comply with their own
zoning regulations, as emphasized in planning literature and case law. The American Planning Association has
argued that "a city should never be given an exemption from the force and effect of its own zoning ordinance,"
highlighting the absence of compelling reasons for self-exemption and the risk of arbitrary governance.
Standard exceptions under California law include conditional use permits, variances, and nonconforming uses,
which require public processes and justifications. The proposed blanket exemption deviates from this, potentially
violating principles of equal application. While state entities may be exempt from local zoning for governmental
purposes, and cities from county zoning extraterritorially, no analogous broad immunity exists for a city from its
own intra-jurisdictional rules. The Attorney General's Opinion No. 14-403 clarifies exemptions in inter-
jurisdictional contexts but does not endorse intra-city self-exemption without conditions.
Furthermore, Government Code Section 65860 mandates that zoning ordinances be consistent with the general
plan. By creating a de facto opt-out for City projects, the amendment may introduce inconsistencies, as it alters
the uniform application intended by the plan. Case law, such as Lesher Communications, Inc. v. City of Walnut
Creek (1990), underscores that initiatives conflicting with general plans are invalid, suggesting similar scrutiny
for this amendment.
This foundation appears weak, as it circumvents established mechanisms like variances, potentially inviting legal
challenges for abuse of discretion or ultra vires action.
Potential Inconsistencies with Existing Zoning Regulations
Title 17 aims to implement the General Plan by regulating land use for orderly development and public welfare.
The amendment's exemption could conflict with specific standards, such as:
• Height and Setback Requirements: Exempting netting or generators ignores Sections 17.70.080 and
17.70.170, which protect views, light, and adjacency.
• Fencing and Walls: Section 17.70.070 addresses ground-level features, but the amendment's broader
definition could allow overhead or intrusive elements without review.
• General Applicability: Section 17.02.030 requires all land and structures to comply, yet the exemption
erodes this uniformity.
Such inconsistencies may violate Government Code Section 65860's consistency mandate, as noted in recent
legislation like AB 821, which reinforces alignment between zoning and plans. Without case-by-case variances,
the amendment risks fragmenting the regulatory framework, leading to ad hoc decisions that undermine public
trust.
Broader Implications for Sensitive Receptors
Sensitive receptors under CEQA include populations vulnerable to environmental impacts, such as children,
seniors, asthmatics, and those with preexisting conditions, as well as wildlife disproportionately affected by
development. CEQA requires early identification, assessment, and mitigation of risks (Public Resources Code
Sections 21000 et seq.), emphasizing protection near residences, schools, parks, and habitats.
Exempted features like fencing, barriers, or technology could:
• Impact Human Receptors: Increase noise, air pollution, or visual intrusions near sensitive sites,
exacerbating health issues without required studies.
• Affect Wildlife: Create barriers to migration, fragment habitats, or cause collisions, as evidenced by
studies on fencing in California. For instance, undercrossings and corridors are vital, yet fences hinder
species like mule deer and amphibians.
Page 9.
The amendment's CEQA exemption claim under Section 15061(b)(3)—asserting "with certainty" no significant
effects—fails the "fair argument" test from cases like Berkeley Hillside Preservation v. City of Berkeley (2015),
where exemptions were invalidated if evidence suggests impacts. Zoning amendments can constitute "projects"
triggering review if they enable physical changes. Recent reforms exempt certain housing but not broad public
projects, underscoring the need for scrutiny here.
Environmental Impacts and CEQA Considerations
1. Habitat Fragmentation. Habitat fragmentation is a significant concern under CEQA review. Wildlife species
such as deer and amphibians are particularly vulnerable to the disruption of natural migration corridors. Physical
features, including fencing and walls, can obstruct movement across landscapes and reduce ecological
connectivity. These disruptions may lead to population isolation, reduced genetic diversity, and diminished
ecosystem resilience.
2. Air and Noise Pollution. Air and noise pollution represent critical human health concerns, especially for
sensitive receptors such as children and seniors. Project components such as generators and other
technological installations can exacerbate pre-existing health conditions in the absence of mitigation strategies.
CEQA requires the evaluation of these effects to ensure that protective measures are implemented to minimize
adverse outcomes.
3. Visual and Physical Intrusion. Visual and physical intrusions affect both human and wildlife receptors.
Infrastructure elements such as barriers and netting can alter environmental settings, diminish aesthetic values,
and increase physical risks. For wildlife, these structures may result in habitat avoidance or altered behavioral
patterns. For human communities, they may reduce the quality of life and increase psychosocial stressors. CEQA
emphasizes the importance of addressing these changes in environmental review.
4. Collision Hazards. Collision hazards are of particular importance for wildlife. Solid barriers and related
features can impede safe movement across natural habitats, increasing the likelihood of injury or mortality. CEQA
review processes consider these risks in the context of ecological integrity and species protection, requiring
appropriate mitigation where impacts are significant.
5. Cumulative Effects. Cumulative effects are especially concerning in vulnerable communities, where multiple
project features may combine to generate long-term, unassessed impacts. Without systematic evaluation, these
effects can exacerbate environmental injustice, concentrating risks in already disadvantaged populations. CEQA
mandates cumulative impact assessments to ensure equitable consideration and sustainable project outcomes.
The potential impacts identified above demonstrate the range of environmental and human health risks
associated with project development. CEQA plays a critical role in ensuring that such risks are adequately
assessed, mitigated, and monitored to safeguard ecological systems and vulnerable populations alike.
In sum, these risks highlight CEQA’s essential role in evaluating, mitigating, and preventing environmental and
community harms associated with project development.
Recommendations and Conclusion
The amendment should be rejected or revised to require variances or CEQA reviews for exemptions. Alternatives
include targeted ordinances or enhanced public input. In conclusion, while addressing administrative hurdles,
the proposal's flaws in legal grounding, consistency, and protection of sensitive receptors outweigh benefits,
potentially exposing the City to litigation and environmental harm.
