DEED: Deed Restriction Listing
Site Mitigation and Brownfields Reuse Program Facility Sites with Deed Restrictions & Hazardous Waste Management Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program (SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land use restriction at the local county recorder’s office. The land use restrictions on this list were required by the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners.

EPA WATCH LIST: EPA Watch List
EPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcement matters relating to facilities with alleged violations identified as either significant or high priority. Being on the Watch List does not mean that the facility has actually violated the law only that an investigation by EPA or a state or local environmental agency has led those organizations to allege that an unproven violation has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

2020 COR ACTION: 2020 Corrective Action Program List
The EPA has set ambitious goals for the RCRA Corrective Action program by creating the 2020 Corrective Action Universe. This RCRA cleanup baseline includes facilities expected to need corrective action. The 2020 universe contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.

Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

RMP: Risk Management Plans
When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance for chemical accident prevention at facilities using extremely hazardous substances. The Risk Management Program Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects of an accidental release, an accident history of the last five years, and an evaluation of worst-case and alternative accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee training measures; and Emergency response program that spells out emergency health care, employee training measures and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings were used as construction materials before the potential health hazards of the tailings were recognized.

PFAS NPDES: Clean Water Act Discharge Monitoring Information Any discharger of pollutants to waters of the United States from a point source must have a National Pollutant Discharge Elimination System (NPDES) permit. The process for obtaining limits involves the regulated entity (permittee) disclosing releases in a NPDES permit application and the permitting authority (typically the state but sometimes EPA) deciding whether to require monitoring or monitoring with limits. Caveats and Limitations:

Less than half of states have required PFAS monitoring for at least one of their permittees and fewer states have established PFAS effluent limits for permittees. New rulemakings have been initiated that may increase the number of facilities monitoring for PFAS in the future.

EDR HIGH RISK HISTORICAL RECORDS
EDR Exclusive Records
EDR MGP: EDR Proprietary Manufactured Gas Plants
The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

1.0 Introduction

1.1 Project Description
The City of Imperial Beach has received ATP Cycle 6 and SANDAG Transnet funds to construct the Palm Avenue Master Project, between Rainbow Drive and Georgia Street. The Proposed Project includes Class IV bicycle facilities, widened sidewalks, new lighting, median and sidewalk landscape improvements, traffic signal modifications, and storm drain updates, among other components.

Figure 1 - Vicinity Map

1.1.1 Existing Drainage Conditions
Palm Ave is a six-lane arterial roadway lined with landscape medians. Existing drainage includes sheet flow, gutter flow, and several independent storm drain systems, all discharging to Otay River. There is generally a crown along the center of the roadway along Palm Ave. At the western limits of the project near Rainbow Dr, there are open drainage channels paralleling the roadway.

Runoff from the project will discharge to the Otay River near its headwaters discharging to the San Diego Bay. City storm drain systems D, H, K, and P will all receive runoff from the project area, though not all of those systems will be directly affected by the proposed improvements. Where these systems discharge to the Otay River, FEMA floodplain mapping indicates Zone AE, which is considered a Special Flood Hazard Area.

1.1.2 Proposed Drainage Conditions
The intent of the proposed drainage is to closely mimic the existing drainage patterns. The project corridor also includes three open drainage channels paralleling the roadway. There will be no significant diversions of drainage areas.

The project is not expected to adversely impact the floodplain nor require changes to the mapping.

1.2 Objectives
This study is prepared in support of CEQA Environmental Permitting, including addressing the following questions:

Would the Project:
a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality?
b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
i. result in a substantial erosion or siltation on- or off-site; ii. substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or offsite;
iii. create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or
iv. impede or redirect flood flows?
d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan

2.0 Methodology

2.1 Rational Method Hydrology
Rational Method peak flow rate calculations have been prepared in accordance with Chapter 3 of the San Diego County Hydrology Manual (County Hydrology Manual). Calculations have been prepared for the 50-year and 100-year events. The Rational Method equation is as follows:

Q=CIA
Where: Q = peak discharge (cfs)
C = runoff coefficient (unitless)
I = average rainfall intensity (in/hr)
A = drainage area (ac)
Palm Ave Multimodal Corridor Improvements
Preliminary Hydrology and Hydraulics Report

Page 3 ends

2.1.1 Runoff Coefficient (C)
Runoff coefficients for each of the project areas has been determined based on percent impervious and soil type. Percent impervious has been determined based on aerial imagery and engineering judgement.

Soil type has been identified using the NRCS Web Soil Survey. The runoff coefficient is then calculated based on the following equation:

C=0.90*(% Imp) + Cp*(1-% Imp)
Where: Cp = Pervious Coefficient for Undisturbed Natural Terrain

2.1.2 Rainfall Intensity (I)
Average rainfall intensity is calculated based on Figure 3-2 of the County Hydrology Manual. The 6-hour precipitation (P6) is determined based on the isopluvial maps in Appendix B of the County Hydrology Manual. The value for P6 should be within 45% to 65% of P24. The duration is assumed to be equal to the time of concentration (Tc).

Time of Concentration
The time of concentration consists of an initial time of concentration (Ti) and travel time (Tt). The minimum time of concentration is 5 minutes.

Tc = Ti + Tt
Ti is approximated using Figure 3-3 of the County Hydrology Manual and is based on FAA equation for shallow uniform flow on runways. The maximum overland flow length for calculating Ti is specified in Table 3-2 of the County Hydrology Manual based on slope and land use.

Tt is calculated based on flow length and velocity. For significant variations in flow type of velocity, multiple Tt values are calculated and added together for the overall Tt. Street gutter flow is estimated based on Figures 3-6 and 3-7 of the County Hydrology Manual. For other urban concentrated conveyance, velocity is determined based on Manning’s Equation or other applicable hydraulic calculations.

2.1.3 Drainage Area (A)
Drainage areas are delineated based upon the best available topographic information. When possible, delineations are field verified for accuracy. Subareas have been delineated as needed based on significant points of interest (i.e. existing or proposed infrastructure, project discharge locations, etc.).

2.2 Hydraulic Design
This preliminary report focuses on the hydraulic capacity specifically of the existing storm drain pipes.

Compliance with inlet capacity and street conveyance requirements will be determined during final design.

The general intent of this project is to maintain the existing drainage function and improve the function where feasible. Since this is an urban retrofit project, the drainage design is not expected to meet new development standards.

Palm Ave Multimodal Corridor Improvements
Preliminary Hydrology and Hydraulics Report

Page 4 ends

Pipe capacity calculations were performed based on Manning’s open channel flow. Full standard step method hydraulic will be performed during final design. At this stage of design, some pipe sized and slopes are assumed, until additional information is acquired. Some capacity calculations are pending offsite hydrologic calculations not included in the scope of this analysis. Offsite pipes which are not a part of the project have been noted as such.

We have also performed CCTV condition assessment of the existing pipes. The condition will be a factor in prioritizing and determining what systems to upgrade as part of this project.

4.0 Conclusions
a) The project will not violate water quality standards or waste discharge requirements. The City is subject to the requirements of the Regional Phase I MS4 Permit (Order No. R9-2013-0001, as amended by Order Nos. R9-2015-001 and R9-2015-0100). The City’s BMP Design Manual outlines the requirements and how they impact development projects. The project is implementing Green Street measures as part of the overall compliance approach. b) The project will not decrease groundwater supplies. The project area is near the Pacific Ocean and has very little runoff infiltrating to the ground. The project will improve conditions by adding landscaping and constructing BMPs.
c) The drainage pattern will not be substantially altered with the project improvements. The proposed drainage pattern will closely mimic existing conditions, as shown in the existing and proposed drainage calculations in Table 1.
i. The exit velocities of the outfall pipe will not significantly change from existing to proposed condition. Analysis shows that most pipes have exit velocities over 5 fps.

Currently, outfall pipes have rip rap to provide erosion control and flow dissipation. ii. There is no substantial increase in runoff being generated in this project. Slight increases in impervious areas may occur due to the construction of wider sidewalks, bus platforms, and curb bulb outs. As the project progresses, landscaping and BMPs will be strategically placed to offset the impact of the additional impervious area that may be added. iii. Based on preliminary analyses, several pipes are not adequately sized, even in the existing condition. To the extent feasible within the budgetary constraints of the project, pipes that are currently undersized will be upsized as part of the improvements.

Additional information from field verification and ground surveying will more accurately determine drainage area delineations and resulting flow captured by the systems. The Palm Ave Multimodal Corridor Improvements

capacity of each existing storm drain pipe with current available information was analyzed in Table 2.
iv. The project does not impede or redirect flood flow. The proposed improvements will improve drainage conveyance and capture along this corridor. d) A very small portion of project at the eastern limit is within the FEMA floodplain Zone AE, which is considered a Special Flood Hazard Area.

Although the northwestern limits of the project are adjacent to a Tsunami Hazard Area, the roadway itself is not considered a Tsunami Hazard Area, according to the California Department of Conservation
The project is not in a seiche zone.
e) This project will not conflict with or obstruct implementation of a water quality control plan.

There is not an existing groundwater management plan within or near the project.

Directions for Application:
(1) From precipitation maps determine 6 hr and 24 hr amounts for the selected frequency. These maps are included in the County Hydrology Manual (10, 50, and 100 yr maps included in the Design and Procedure Manual).
(2) Adjust 6 hr precipitation (if necessary) so that it is within the range of 45% to 65% of the 24 hr precipitation (not applicaple to Desert).
(3) Plot 6 hr precipitation on the right side of the chart. (4) Draw a line through the point parallel to the plotted lines. (5) This line is the intensity-duration curve for the location being analyzed.

Application Form:
(a) Selected frequency ___ year

(b) p6 = ---in., P24 = ---'P 6 = %(2) 24
(c) Adjusted p6<
2> = ___ in.
(d) tx = __ min .
(e) I = __ in./hr .

Note: This chart replaces the Intensity-Duration-Frequency curves used since 1965.

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

This product is generated from the USDA-NRCS certified data as of the version date(s) listed below.

Soil Survey Area: San Diego County Area, California
Survey Area Data: Version 20, Aug 30, 2024
Soil map units are labeled (as space allows) for map scales 1:50,000 or larger.

Transportation CEQA Memorandum

3900 5th Avenue, Suite 310  San Diego, CA 92103  619-795-6086 www.CRAmobility.com
TO: Roberto Ruiz-Salas, PE; CR Associates
FROM: Trevor Briggs, PE, CR Associates
DATE: October 31, 2025
RE: Palm Avenue Complete Multi-Modal Corridor Project – Transportation CEQA Memorandum The purpose of this Transportation CEQA Memorandum is to document the results of the transportation analysis conducted for the Palm Avenue Complete Multi-Modal Corridor Project (the “Project”) in the City of Imperial Beach, California. This memorandum evaluates the Project’s features against the transportation-related questions presented in Appendix G of the CEQA Guidelines to determine whether the Project would result in a significant transportation-related impact under CEQA.

Project Description
The Palm Avenue Complete Multi-Modal Corridor Project proposes to transform Palm Avenue between Rainbow Drive and Georgia Street into a multimodal complete street corridor that improves safety, accessibility, and visual character. The project will strengthen regional connectivity by linking with surrounding active transportation initiatives, including the Bayshore Bikeway, 9th Street Enhancement Project, and Border to Bayshore project. The general suite of traffic-related improvements proposed along the corridor will include the following:
• Class IV protected bike lanes next to the curb, separated by a concrete 2-foot-wide median within a 3’ buffer, where existing public right-of-way allows. • Provide transit amenities.
• Incorporate on-street parking configuration changes, relocations, and removals at selected locations.
• Realign select intersections to improve operations and safety. • Widen existing sidewalk to 10’ wide where possible.
• Construct curb extensions with directional ramps at all side street crossings. • Rebuild alley entrances, driveways and curb ramps to be ADA compliant.

All traffic signal modifications will be designed in conformance with California Manual on Uniform Traffic Control Devices (CA MUTCD) standards and in coordination with the City’s traffic engineering department
Transportation Impact Analysis
The following addresses the four transportation-related questions from Appendix G of the CEQA Guidelines.
a) Would the project conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? No. Based on review of the Palm Avenue Complete Multi-Modal Corridor Project application, the proposed improvements would not conflict with any adopted program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities. The Palm Avenue Complete Multi-Modal Corridor Project Page 2 Transportation CEQA Memorandum
project is consistent with several adopted City and regional planning documents, including the City of Imperial Beach Bicycle Master Plan, Local Road Safety Plan (LRSP), and the SANDAG Regional Plan.

The City of Imperial Beach Bicycle Master Plan recommends a Class I Bike Path along State Route 75 (SR-75) west of Rainbow Drive and a Class II Bike Lane along Palm Avenue from Delaware Street to the eastern City limit. A bicycle facility is not recommended in the Bicycle Master Plan along SR-75 from Rainbow Drive to Delaware Street. The Palm Avenue Complete Multi-Modal Corridor Project proposes Class IV Protected Bike Lanes along SR-75/Palm Avenue from Rainbow Drive to eastern City limit. Since the Project is upgrading the bicycle facilities along Palm Avenue in the Bicycle Master Plan to protected bike lanes, the Project would be considered consistent with the Bicycle Master Plan.

The City’s Local Road Safety Plan recommended safety-related improvements along Palm Avenue, such as the installation of bicycle crossings at signalized intersections along Palm Avenue, as well as signal upgrades and curb bulb-outs at the intersections of Palm Avenue at 9th Street and Palm Avenue at 13th Street. The Palm Avenue Complete Multi-Modal Corridor Project proposes similar improvements to the LRSP, as noted in the project description. As such, the Project would be considered consistent with the City’s LRSP.

The SANDAG 2021 Regional Plan designates Palm Avenue as a Regional Arterial with operational and technology improvements as part of the 2050 Complete Corridor Bike Network and Arterials, as well as a roadway with Local Bus service. It should also be noted that Palm Avenue in the City of Imperial Beach is within a Regional Mobility Hub Area, which are considered communities with a convenient mix of travel choices, safer streets, and supporting amenities that help people get to and from transit services without relying on a car. The Palm Avenue Complete Multi-Modal Corridor Project will provide Class IV Protected Bike Lanes, transit amenities, and improve safety and operations at signalized intersections along Palm Avenue to promote multimodal activity in line with the SANDAG Regional Plan.

Therefore, the Project would be considered consistent with the SANDAG Regional Plan.

As noted above, the Project is in compliance with the goals and policies of local and regional guiding transportation plans.
b) Would the project conflict or be inconsistent with CEQA Guidelines §15064.3, subdivision (b)? No. CEQA Guidelines §15064.3 sets vehicle miles traveled (VMT) as the metric for transportation impacts. For transportation projects, the key question is whether the project would induce additional driving; projects that reduce or do not increase VMT are generally considered less than significant. A qualitative explanation is acceptable when models are unnecessary or the effects are clear.

The Governor’s Office of Planning and Research (OPR) Technical Advisory on Evaluating Transportation Impacts in CEQA (Technical Advisory, December 2018) states that “…active transportation projects generally reduce VMT and therefore are presumed to cause a less-thansignificant impact on transportation.” The Palm Avenue Complete Multi-Modal Corridor Project is a active transportation project, as noted by the improvements in the project description.

As a result, the project would not conflict with §15064.3(b) and would result in a less-than-significant transportation impact under the VMT metric. Any construction-period traffic effects would be temporary and managed through standard measures (i.e. a traffic management plan). If future design changes were to introduce new auto capacity, a project-level induced travel/VMT analysis would be warranted.

c) Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No. The project would not substantially increase hazards due to geometric design features or incompatible uses. The roadway improvements and traffic signal modifications as noted in the project description will be designed to applicable standards. Driveway and alley treatments would be rebuilt to current ADA standards with visibility triangles and marked conflict zones, and intersection geometry may be refined (i.e. tighter curb radii, protected-intersection elements) to lower turning speeds. All improvements will be designed to applicable City standards and the CA MUTCD. With standard construction-period traffic control to manage temporary conditions, the project would not create new geometric or use hazards; therefore, the impact would be less than significant. d) Would the project result in inadequate emergency access? No. The project would not result in inadequate emergency access. All improvements occur within the existing Palm Avenue right-of-way and are intended to calm speeds and organize space, not to restrict access. Targeted lane reductions along certain segments, curb extensions, protected bikeways, and median/separator elements would be designed in coordination with the City’s fire and emergency services to maintain required California Fire Code clear widths and turning templates at intersections, alleys, and driveways. Curb extension geometry, separator gaps at crossings, and parking management would be laid out to preserve apparatus turning paths and sight lines and traffic signal modifications would be coordinated with emergency responders to maintain existing emergency operations.

During construction, the contractor would implement a Traffic Management Plan to keep emergency routes open, provide flagging or temporary lane control as needed, and maintain continuous access to adjacent properties. With these design commitments and standard construction-phase measures, the project would not create barriers to emergency response or evacuation; therefore, the impact would be less than significant.

Conclusion
The Palm Avenue Complete Multi-Modal Corridor Project implements complete-streets upgrades within existing right-of-way, including protected bikeways, targeted lane reductions along certain segments, wider sidewalks, ADA curb ramps, curb extensions, parking management, and signal enhancements, all designed consistent with the CA MUTCD and coordinated with City traffic engineering and emergency services. The project does not add general-purpose vehicle capacity and includes standard construction-phase traffic management to maintain access.

Accordingly: (a) it implements, and does not conflict with, applicable City and regional circulation policies (less-than-significant/no conflict); (b) it is consistent with CEQA Guidelines §15064.3(b) because it repurposes capacity and would not induce VMT (less-than-significant); (c) it employs recognized safety countermeasures and avoids hazardous geometry or incompatible uses (less-thansignificant); and (d) it maintains required clear widths/turning paths and manages work zones to preserve emergency routes (less-than-significant). Therefore, the Project would have a less-thansignificant transportation impact.

CORRIDOR PROJECT LOCATED WITHIN THE CITY OF IMPERIAL BEACH, CALIFORNIA Dear Mr. Dyche:

Pursuant to California Assembly Bill (AB) 52, the City of Imperial Beach is providing you with notification of the Palm Avenue Multimodal Corridor Project (Project), located between Rainbow Drive and 13th Street in the City of Imperial Beach, San Diego County, California. While the City of Imperial Beach has not yet received a request from your tribe to be notified of specific projects within a designated geographic area, we are reaching out to all groups listed on the California Native American Heritage Commission’s Sacred Lands File consultation list in a good faith effort to provide notification of the proposed Project to groups that are traditionally or culturally affiliated with the geographic area of the proposed Project.

PROJECT NAME: Palm Avenue Multimodal Corridor Project
PROJECT NO: Project No. 17736
PROJECT LOCATION: The Project spans approximately 1.75 miles along Palm Avenue, between Rainbow Drive on the west and Georgia Street on the east, in the City of Imperial Beach, San Diego County, California.

PROJECT DESCRIPTION:

The Project is designed to transform Palm Avenue into a safer, more accessible, and visually enhanced multimodal corrdior. The Project is approximately 5,711 linear feet and covers approximately 59.8-acres.

The Project is proposing several improvements including establishing Class IV protected bike lanes, widening existing sidewalks, installing shade canopy trees, ornamental lighting, improving median landscape, replacing median vehicle lighting, constructing curb extensions with directional ramps, and rebuilding alley entrances, driveways and curb ramps to be ADA compliant.

The Project falls in Township 18 South, Range 2 West, and Sections 19, 20, and 29 of the Imperial Beach, California U.S. Geological Survey 7.5-minute Quadrangle (Figure 1). The City of Imperial Beach will act as the lead agency under California Environmental Quality Act (CEQA).

Cultural resource identification efforts undertaken for the Project to date include a records search of the Project area obtained from the South Coastal Information Center (SCIC) on April 8, 2025 by Dudek; a cultural resources field survey conducted by Dudek on May 15, 2025; and a review of historical maps and aerial imagery depicting the Project area. The records search identified one built environment resource, P-37-026582 (Western Company Salt Works), as intersecting the Project area. During the survey, one newly identified historic period site, PA-MM-S-001, was recorded on the surface consisting of a refuse scatter of glass and ceramic fragments. No precontact indigenous archaeological resources were observed during survey,
If you have any comments or concerns regarding tribal cultural resources (as defined in California Public Resources Code section 21074) in relation to the proposed Project, please provide a written request for consultation via email to D. Todd Philips, City of Imperial Beach Community Development Director ([email protected]). The California Native American tribe has 30 days of receipt of this notice to request consultation pursuant to California Public Resources Code section 21080.3.1. Please include the name of a designated lead contact person.

If you have any questions, please don’t hesitate to contact me.

Sincerely,
D. Todd Philips, Ed.D.
