7.5.4.2.1 Action W-2.1: Support East County Advanced Water Purification (ECAWP) Program The East County Advanced Water Purification (ECAWP) Program, a collaborative effort from the Helix Water District, County of San Diego, City of El Cajon, and Padre Dam Municipal Water District, will deliver water from a new local water supply starting 2027.33 The percentage of La Mesa’s water supply that will be from ECAWP is not available, therefore, the percentage of all partner agencies’ water supply that will be from ECAWP, 28.6%, is used as a proxy for La Mesa. The local water supply will replace imported raw water purchases from SDCWA. The emissions avoided are calculated based on the difference between upstream energy intensity and ECAWP energy intensity (tertiary treatment), and the difference between the statewide electricity emission actors and the SDCP emission factors.

7.5.5 Waste Reduction
7.5.5.1 Measure WR-1 through Measure WR-5
The goal of Measure WR-1 through Measure WR-5 is to achieve: (1) 75% waste diversion rate by 2035 and 90% waste diversion by 2045. The 75% waste diversion rate would result in 3.1 pounds per person per day (PPD) waste disposed in landfills in 2035, and the 90% waste diversion rate would result in 1.2 PPD waste disposed in 2045.
The city has not conducted a waste characterization study, therefore, the 2016 waste composition data (used in the 2016 GHG inventory) from San Diego are used and held constant through 2045. 35 The
emissions avoided from increasing the waste diversion rate is the difference between the waste 33 East County Advanced Water Purification Program. 34 The percentage of ECAWP to total water supply (of all partner agencies) was provided by Helix Water District to EPIC (May 2024). The advanced water treatment energy intensity (beyond tertiary treatment level to achieve drinking water quality), 1,584 kWh/acre-foot, is provided by Padre Dam Municipal Water District to EPIC through a different project. 35 Recent State actions include organic waste recycling, which may reduce the mixed waste emission factor in future years.

RE: La Mesa Climate Action Plan - GHG Reduction Determination – Technical Memorandum
The purpose of this technical memorandum is to document the potential Green House Gas (GHG) reduction associated with the transportation measures presented in the City of La Mesa Climate Action Plan.
Introduction
In accordance with the City of La Mesa’s goals to reduce greenhouse gas (GHG) emissions, an update to the existing City of La Mesa Climate Action Plan (CAP) has been proposed to revise target years and to align with the State of California’s GHG goals. This update aims to adjust the target years for GHG reduction and ensure they are in sync with the state's GHG reduction goals. The update includes the following measures:
• T-1: Bicycle and Pedestrian Infrastructure Development • T-2: Transportation Demand Management Program
• T-3: Municipal Transportation Demand Management Program (with transit subsidy for all City Employee)
• T-4: Mixed-Use and Transit-Oriented Development and Parking Pricing (Expand Parking meters area and parking rate)
• T-5: Alternative Refueling Infrastructure Development • T-6: Municipal Fleet Transition
• T-7: Develop a Flexible Fleets Program
• T-8: Signal Optimization & Install Roundabouts
Discussion of each measure is provided below and supporting information are provided in Attachment A.
Measure T-1: Bicycle and Pedestrian Infrastructure Development Developing planned bicycle and pedestrian infrastructure, along with improving existing facilities, will create a complete street environment for all users in La Mesa. Completing these facilities will encourage residents to shift from vehicle dependency to alternative transportation modes. The 2023 active transportation traffic counts show that pedestrian activities in La Mesa are concentrated around residential streets, connecting neighborhoods to local amenities such as schools and community centers. By constructing missing sidewalks, improving existing ones, and enhancing bicycle facilities, the City can reduce car dependency. Since walking and biking complement each other and users may choose different modes based on daily needs, the GHG reduction calculation groups these measures together for a comprehensive assessment.
According to the City of La Mesa's Sidewalk Master Plan, the City currently has 169.8 miles of existing sidewalks, 67.2 miles of proposed sidewalks, and 36.9 miles without sidewalks. Some areas without
sidewalks are located in the City's more historic districts. However, to enhance connectivity, it is anticipated that these areas will be upgraded to walkable conditions as redevelopment occurs.
Therefore, this measure assumes that the City will construct 107.1 miles of new sidewalks by 2045, with approximately half of that completed by 2035. Additionally, the measure assumes the completion of the Citywide bicycle network. According to the City of La Mesa Geographical Information Database there are currently 19 miles of Class II or better bicycle facilities in the City of La Mesa, with an additional 6.6 miles of bicycle facilities planned for future improvements.
The greenhouse gas (GHG) reduction associated with this measure was determined using Measures T-18 and T-20 from the California Association of Air Pollution Control Officers' Handbook for Analyzing Greenhouse Gas Emission Reductions, Assessing Climate Vulnerabilities, and Advancing Health and Equity (CAPCOA Handbook). Measure T-18 estimates that completing the missing sidewalks could reduce citywide GHG emissions by up to 1.58% by 2035 and 3.15% by 2045. Additionally, completing the City's bicycle network might further reduce citywide GHG emissions by an additional 0.22%.
According to the CAPCOA Handbook, combining multiple measures can enhance their effectiveness, which should be calculated by multiplying the individual reduction percentages. This is done using the following formula:
Reductionsubsector= = 1 − [(1 − A) × (1 − B) × (1 − C)] Where A, B, and C represent the individual reduction percentages for the measures within each subsector.
After applying this formula and rounding it down as a conservative estimate, the total GHG reduction remains at 1.58% by 2035 and 3.15% by 2045. Table 1 displays the GHG reduction associated with this measure.

Measure T-2: Transportation Demand Management Program
The City will adopt a Citywide Transportation Demand Management Program, participation in the program is required for all new development and redevelopment, excluding single family residential development but would be require for development where there are more than one dwelling unit per parcel i.e. duplexes or other density bonus type of development.
This measure would require the City to adopt an ordinance to develop a Citywide Transportation Demand Management (TDM) program, along with an annual or biennial monitoring report. Based on Measure T-6 from the CAPCOA Handbook, this initiative could potentially reduce Vehicle Miles Traveled (VMT) by up to 26% per Project, thus the reduction is only applied to the GHG and VMT associated with redevelopment project. Table 2 outlines the calculation of GHG reductions for the years 2035 and 2045.

Measure T-3: Municipal Transportation Demand Management Program Developing a TDM program focused on City staff will offer significant return on investment by encouraging alternative modes of transportation. This program aims to enhance the quality of life for City staff while reducing GHG emissions and dependency on single-occupancy vehicles. This program shall include transit subsidies for municipal employees. Table 3 displays the GHG reduction calculation.

1 The SANDAG Regional Transportation Model for the year 2016 found that the transit mode share in the City of La Mesa is 5.5%. A research paper titled “Employer-paid transit subsidies and travel behavior: Experimental evidence from Vancouver hotels” found that the percentage of new transit users resulting from a transit subsidy varies depending on the employment location and the availability of on-street parking. The study also showed that even in areas with high driving dependency, a 50% transit subsidy could lead to a mode shift of up to 6%, meaning a 6% reduction in vehicle miles traveled (VMT). Since this strategy is combined with an increase in parking prices, it is assumed that the transit subsidy would be 50% or greater, potentially doubling the number of transit users. https://pdf.sciencedirectassets.com/778770/1-s2.0-S2667091721X00027/1-s2.0-S2667091721000066/main.pdf?
T-4: Mixed-Use and Transit-Oriented Development and Parking Pricing (Expand Parking meters area and parking rate)
The City will identify areas capable of supporting increased population or employment within a 1/4- to-1/2-mile walking distance to transit stops, such as trolley stations. High-density affordable housing will be supported near LM-5, Amaya Trolley Station, and LM-7, Spring Street Trolley Station, designated as regional Smart Growth Areas. The City will collaborate with SANDAG, MTS, and other regional jurisdictions to enhance local transit service and micro-mobility options in these higherdensity, mixed-use areas to attract new potential transit riders. Participation in future regional planning and programs will lay the foundation for long-term VMT reduction opportunities in La Mesa.
Development within ½ mile of a major transit stop such as the Spring Street and Amaya Trolley Stations are not required to meet minimum parking standards. The City should develop and adopt a parking management plan that optimizes the parking fees and parking availability around TOD to encourage alternative modes of transportation and discourage single occupancy vehicle dependency. One significant tool for this strategy is to update the parking pricing (parking meter) to reflect market conditions and expand the parking meter area. By pricing parking meters (increase parking meter rate) to reflect market conditions and expanding the parking meter areas to cover areas within the City of La Mesa that are medium to high density, the City of La Mesa would be able to incentivize residents/business owners/visitors to select alternative mode of transportation. This action assumed that the City of La Mesa would increase parking meter pricing and expand the parking meter area to cover other high demand areas such as those located near Grossmont Mall or the Sharp hospital.
This measure assumes that the City would also increase the parking meter rate from $0.75 currently to $2.25 by 2035 and $3.25 by 2045. Based on measure T-24 of the CAPCOA handbook, this would potentially reduce the GHG associated with the area where paid parking is in effect by 17% by the year 2035 and 30% by the year 2040.

Measure T-6: Municipal Fleet Transition
The City plans to convert gasoline vehicles within its fleet to ZEVs and to switch eligible heavy-duty fleet vehicles to renewable diesel. Assuming the municipal fleet size does not increase from the baseline of 150 vehicles2.

T-7: Signal Optimization & Roundabout Installation/Traffic Calming The objectives of Measure T-7 are twofold: (1) to synchronize traffic signals at 58 intersections by 2035, optimizing fuel efficiency through smoother traffic flow, and (2) to install 10 new roundabouts or traffic circles by 2045. The impact of traffic signal synchronization and roundabouts on fuel reduction is influenced by traffic volume and the size of the intersections on arterial roads. A study of a similar traffic signal synchronization project found that annual fuel savings per intersection averaged around 2,400 gallons5. Of the 58 signalized intersections, 53 are connected to the central traffic management center at City Hall, it is anticipated that by 2045 all signals would be connected to a centralized Traffic Management Center.
Additionally, the City is currently working on converting key corridors into complete street environments by constructing new roundabouts or converting signalized intersections into roundabouts. These roundabouts are expected to enhance traffic operations, reduce speeds, provide traffic calming, and decrease GHG emissions6.

City of La Mesa CAP Update Implementation Cost Analysis Summary of Findings
Introduction
This report summarizes the findings of the City of La Mesa Climate Action Plan Update (CAP Update) Implementation Cost Analysis report conducted by the Energy Policy Initiatives Center (EPIC) at the University of San Diego. The analysis summarizes the costs and funding needs for the City of La Mesa (the City) to implement the CAP Update. While the analysis for this report evaluated costs for the first five fiscal years (FY25 to FY29), CAP Update measures could have associated costs beyond this time frame.
Key Findings
Total CAP Update Implementation Costs by Measure
Based on data provided by City staff, the total estimated cost to implement CAP Update measures over the first five fiscal years (FY 25 to FY 29) would be about $23 million. About $14 million (60%) of these costs are associated with existing programs that would have happened regardless of the CAP Update (Table 1). The remaining $9 million (40%) would be the cost to implement new and expanded programs in the CAP Update.

This summary presents total costs anticipated during the first five fiscal years of CAP Update implementation—FY 25 to FY 29. The costs are estimates based on input and discussions with City of La Mesa staff that would participate in anticipated implementation tasks included in the draft CAP Update.
The general steps in the process to estimate CAP Update implementations costs were to: (1) determine the actions required to implement CAP Update activities; (2) define workload associated with these tasks; and (3) estimate staffing levels and associated costs.
Identify Implementation Actions -- The CAP Update includes implementation actions that represent the expected workload to implement CAP Update activities. The CAP Update comprises measures that include specific programs, policy actions, and associated actions that will be implemented to reduce GHG emissions. The CAP Update includes 21 CAP measures, 30 Main Actions, and 123 Implementation Actions.
This analysis also considers the CAP Coordination and Reporting measure and related actions.

Establish Preliminary Cost Estimates
Once the implementation actions were developed, City of La Mesa staff estimated staffing effort (in hours) and non-staffing costs like capital, professional services (e.g., consultants), and others that would be required to implement CAP Update activities. To facilitate and standardize the collection of implementation cost data provided by staff across departments, EPIC created a data collection template. Staff conducted meetings with department managers and staff representatives to further discuss cost estimates and cost data collection.
Quality Assurance and Quality Control (QA/QC)
Quality control and data validation occurred at several stages. Primary validation occurred after total estimated costs and level of effort were collected. EPIC and City staff performed an internal quality control check, updated key managers, and reviewed costs with department managers and staff.
