D. Economic Considerations
The Los Angeles Water Board recognizes that economic information, including cost information, is invaluable for informed decision-making and for the evaluation and improvement of policies and practices. Economic information is also critical for Permittees to manage their assets, implement cost-effective programs, and develop successful funding strategies to achieve overall improvements in water quality within the region.

The Legislature did not define “economic considerations” in California Water Code section 13241. As noted in City of Arcadia I, there is no reported court decision analyzing the “economic considerations” phrase of the statute. In City of Burbank, the California Supreme Court, “without discussion, concluded that in adopting Water Code section 13241 the Legislature intended ‘that a regional board consider the cost of compliance [with numeric pollutant restrictions] when setting effluent limitations in a wastewater discharge permit.’ (Italics added.).” (135 Cal.App.4th at 1415.) While the California Supreme Court assumed “economic considerations” includes costs of compliance, it did indicate that this factor is broader. (City of Burbank, 35 Cal.4th at 618 [noting that when a regional board is considering whether to make pollutant restrictions in a permit more

stringent than federal law requires, “California law allows the board to take into account economic factors, including the wastewater discharger's cost of compliance.” (emphasis added.)].) As discussed in the introduction to this Part XIII, in City of Duarte, the Court of Appeal held that “…the Water Control Boards are charged with taking into account economic considerations, not merely costs of compliance with a permit … economic considerations also include, among other things, the costs of not addressing the problems of contaminated water.” (City of Duarte, supra, 60 Cal.App.5th at 276.) Since the Los Angeles Water Board has broad discretion in how it considers this factor, the Board interprets this factor as not only requiring a consideration of the costs of compliance, but also other relevant economic factors such as the societal and environmental costs of not adequately controlling MS4 discharges and cost savings associated with capture and beneficial use of stormwater and non-stormwater to offset the need to purchase imported water.

Many of the costs that will be incurred by permittees as a result of implementing the Order are not fundamentally new. MS4 permits, and stormwater and urban runoff management programs to implement MS4 permit requirements, have been in place in the Los Angeles Region for 30 years. Since the MS4 permits issued in the 1990s, Permittees have been required to effectively prohibit non-stormwater (i.e., dry weather urban runoff) discharges that are a source of pollutants to receiving waters. Since the late 1990s and early 2000s, Permittees have been required to ensure that their MS4 discharges do not cause or contribute to an exceedance of water quality standards (also known as “receiving water limitations”) in receiving waters. Costs incurred by Permittees to implement the Order will largely be related to continued efforts to meet these longstanding requirements. Furthermore, all three prior permits included requirements to implement WQBELs consistent with the assumptions and requirements of applicable TMDL wasteload allocations. There are only a limited number of new TMDL-related requirements in the Order (see Table F-25). Nonetheless, as described below, the two methods used to project the cost of compliance assume that no costs have been incurred to date (i.e., expenditures incurred to date to implement TMDLs and WMPs/EWMPs have not been subtracted from the total projected costs). This was done for consistency and ease of calculation. As a result, projected costs are conservative overestimates.

The Los Angeles Water Board recognizes that these costs of compliance are significant and that many Permittees have limited resources to implement actions to address their MS4 discharges. Based on the economic considerations below, the Board has structured the permit as flexibly as possible to give Permittees the opportunity to sequence actions to address the highest water quality priorities; options to demonstrate compliance; the ability to customize their control measures based on local conditions, including the “minimum control measures”; sufficient time to comply (in many cases decades from the time the TMDL was established); opportunities to request time extensions based on economic factors among others; and the ability to collaborate and pool their resources to implement programs and projects to achieve compliance and to also collaborate and pool their resources to monitor their compliance. The inclusion of a voluntary watershed management program alternative compliance pathway allows Permittees to submit a plan, either individually or in collaboration with other Permittees, for Los Angeles Water Board approval that allows for actions to be customized and prioritized based on specific watershed conditions and needs. The Order also allows Permittees to customize monitoring requirements, which they may do individually, or in collaboration with other Permittees. Permittees can choose to implement the least expensive measures that are effective in meeting the requirements of the Order.

The Permittees’ choices regarding how to comply can take into account the specific conditions within the watershed, such as:
• Types of pollutants targeted
• Site characteristics (e.g., existing infrastructure, land use, infiltration potential) • Costs of controls
• Compliance schedules
• Current compliance rates
• Other socio-economic factors, technology, inflation, risks, regulatory framework Further, the WMP/EWMP compliance alternative provided in the prior Los Angeles County MS4 Permit and City of Long Beach MS4 Permit, and which is included in the Order, allows Permittees to adapt their programs based on new data and information to be more cost-effective.

The Watershed Management Program proposed by the Rio Hondo/San Gabriel River Water Quality Group is an example of this. The Los Angeles County Permittees participating in this group are the cities of Arcadia, Bradbury, Duarte, Monrovia, and Sierra Madre, the County of Los Angeles, and the Los Angeles County Flood Control District. On April 21, 2016, the Los Angeles Water Board approved the Group’s EWMP pursuant to the 2012 Los Angeles County MS4 Permit. At that time, the Group estimated that the cost for the entire program exceeded $1.4 billion. On March 30, 2018, the Group submitted proposed modifications to its approved EWMP pursuant to the adaptive management provisions of the 2012 Los Angeles County MS4 Permit. The proposed revised EWMP entailed extensive and significant modifications to the approved EWMP, including an updated Reasonable Assurance Analysis, changes to watershed control measures, and changes to interim compliance deadlines. From March 2018 to December 2018, the Los Angeles Water Board worked closely with the Group on its proposed revisions. On December 17, 2018, the Group submitted its proposed revised EWMP. On April 2, 2019, the Los Angeles Water Board approved the modifications to the Group’s EWMP proposed on December 17, 2018. The Group now estimates the cost of their revised program to be $121.8 million, or approximately 9% of the original estimated cost. The deadlines for completion of these projects are 2026 for the San Gabriel River watershed portion, and 2028 for the Los Angeles River/Rio Hondo watershed portion.372
The Order also does not require permittees to fully implement all requirements within a single permit term; if Permittees demonstrate they are meeting established interim requirements and schedules that demonstrate progress toward final compliance, then they are complying during the term of the Order, i.e., Permittees do not have to comply with many final WQBELs and receiving water limitations during the 5-year term of the Order. Therefore, the costs to achieve final compliance will be spread out and incurred incrementally over several permit terms. Permittees may also request time schedule orders, where justified, to meet WQBELs and receiving water limitations where final compliance deadlines have passed, and Permittees need additional time to achieve compliance. Lastly, the Order includes several reopener provisions whereby the Board 372 Rio Hondo/San Gabriel River Water Quality Group, Rio Hondo/San Gabriel River Revised Watershed Management Program, May 17, 2019. Note that approximately 30% of the original cost estimate was for implementation in the City of Azusa, which is no longer a participant in this group.

can modify the Order based on new information gleaned during the term of the Order and/or to modify the Order to reflect revisions to TMDLs, including schedules and final deadlines.

1. Los Angeles Water Board’s Consideration of Projected Costs to Comply with the Order
The following is a high-level estimate of the possible range of projected costs to comply with the Order, including compliance with the WQBELs that have been incorporated consistent with available TMDL wasteload allocations. The Board notes that cost of compliance with the WQBELs is inextricably tied to compliance with the other requirements in the Order, including compliance with receiving water limitations, the prohibition on discharges of non-stormwater, and stormwater management program minimum control measures.
a. Sources of data. The costs of implementing the Order were examined by primarily utilizing three sources of data:
i. Estimates of the cost of complying with TMDL wasteload allocations assigned to MS4 discharges, which the Board developed and considered during the establishment of each TMDL. (Used in Method 1.) These estimates were presented in TMDL Staff Reports. As this indicates, there are instances outside of the Order where the Board previously considered economics as it relates to Permittees’ costs of compliance. In the case of TMDLs, these considerations resulted in many lengthy schedules for TMDL implementation, particularly for pollutants associated with stormwater (i.e., wet weather) discharges from MS4s.

Similarly, the State Water Board considered costs when adopting the Trash Amendments, which included a new water quality objective for trash and implementation provisions, including a discharge prohibition, which have been incorporated into the Order.373
ii. Estimates of the cost of fully implementing Watershed Management Programs and Enhanced Watershed Management Programs developed to comply with MS4 permit requirements. (Used in Method 2.) iii. Annual expenditure and budget data that are self-reported by the Permittees in their annual reports. (Used in Methods 1 and 2.) b. Methods of Estimating Costs and Reported Costs. The Los Angeles Water Board used two methods to estimate a possible range of costs to comply with the Order.

Method 1: In the first method, the Los Angeles Water Board analyzed cost estimates that the Board had developed during the adoption of TMDLs and documented in TMDL Staff Reports. Note that for this method, we conservatively assume that no costs have already been incurred by Permittees. However, we know that Permittees have incurred costs associated with implementation of their programs such that the remaining cost for achieving final compliance under the Order is some fraction (less than 100%) of the original cost estimate.

ATTACHMENT F – FACT SHEET F-323
Method 2: In the second method, for Permittees in Los Angeles County, the Los Angeles Water Board staff compiled cost estimates of implementing structural BMPs presented in Watershed Management Programs and Enhanced Watershed Management Programs. For Permittees in Ventura County, Los Angeles County Permittees’ anticipated costs were used to project costs to implement similar Watershed Management Programs in Ventura County. Note that in this method, similar to above, we apply the conservative assumption that little to no money has been spent during the prior and current permit terms to implement projects in the Watershed Management Programs and Enhanced Watershed Management Programs that were approved in 2015-2016 or, in the case of Ventura County Permittees, to implement projects to achieve TMDLs that were first incorporated into the 2009 Ventura County MS4 Permit.

Additional EWMP Development Costs: Estimates from Methods 1 and 2 were considered along with Ventura County’s initial costs of developing EWMPs and WMPs. Ventura County currently does not participate in any EWMP or WMP but may develop EWMPs (now referred to as WMPs) in the next permit term. Ventura County conducted its own analysis in order to estimate development costs.374
Additional Stormwater Management Program Costs: Estimates from Methods 1 and 2 were considered along with Permittees’ annual reported costs for existing elements of their stormwater management programs. These annual reported costs were tabulated based on the reported costs of implementing their stormwater management programs as well as costs associated with program management, monitoring programs, and a category described as “Other.” Most of these annual reported costs are incurred in addition to structural BMP costs calculated in Methods 1 and 2. In these annual reported costs, some Permittees reported costs for capital projects, Regional Projects, Green Streets, and Restoration Projects, which were removed to avoid double counting. As noted below, there is wide variability in the Permittees’ reported cost of compliance, which is not easily explained.375
c. Method 1: Projected Costs from TMDL Staff Reports
As noted above, in the first method for estimating the projected cost to comply with the Order, the Los Angeles Water Board used its analyses regarding costs of TMDL compliance.

As noted earlier, for the most part, the TMDL provisions in the Order are not new but rather continuing requirements from the prior three permits. Of the 45 TMDLs incorporated in the Order, only three are new for Los Angeles County Permittees, including the City of Long Beach, and six are new for Ventura County Permittees (see Table F-25). Nevertheless, the Los Angeles Water Board acknowledges Permittees will need to complete additional implementation actions during the term of the Order to make progress 374 Larry Walker Associates, “Preliminary Ventura County MS4 Permit Structural BMP Implementation Cost Estimate,” dated June 1, 2017.

towards, and ultimately achieve, compliance with the TMDL provisions where final compliance deadlines have not yet passed and/or compliance has not yet been achieved.

As also noted earlier, the Board previously considered the cost of complying with TMDL wasteload allocations assigned to MS4 discharges during the establishment of each TMDL. The costs of complying with these TMDLs, including the WQBELs derived from the TMDL WLAs, which are incorporated into the Order, are not additive. For example, the costs estimated for compliance with a TMDL for one pollutant in a watershed, such as metals, can be applied to the costs to achieve compliance with a TMDL for another pollutant in the same watershed, such as pesticides, because the same implementation strategies can be used for both pollutants. Several MS4 permittees have recognized this opportunity in the multi-pollutant TMDL implementation plans they have submitted (e.g. Ballona Creek Metals/Bacteria TMDLs and Machado Lake Pesticides/Nutrients TMDLs). In other words, the estimated cost of complying with the Ballona Creek Metals TMDL can apply to metals, pesticides, PCBs, and bacteria. The costs for complying with trash TMDLs are based on different implementation strategies (e.g., full capture devices), but those strategies are effective at removing metals and toxic pollutants as well.376 Thus, the costs estimated for each TMDL should not be added to determine the cost of compliance with all TMDLs. The staff reports for the various TMDLs include this explanation, and also discuss the cost efficiencies that can be achieved by treating multiple pollutants. Further, as noted earlier, the Board’s consideration of the cost of compliance in establishing each TMDL has resulted in lengthy implementation schedules to achieve water quality standards. These implementation schedules have been used to establish compliance schedules in the Order.

The Los Angeles Water Board compiled the cost of complying with TMDL wasteload allocations assigned to MS4 discharges in a staff memo titled “2020 Regional MS4 TMDL Compliance Costs,” dated July 17, 2020 (TMDL Staff Report Cost Memo). Using costs estimated during the establishment of TMDLs, the TMDL Staff Report Cost Memo estimated the total capital cost of implementing the 45 TMDLs included in the Order to be $5.0B with total annual operation and maintenance (O&M) costs of $419.2M, yielding a total 20-year cost of $13.4B in 2019 dollars, undiscounted. This estimate is broken down by watershed in Table F-28, below. The estimated cost by Permittee is available in the Administrative Record for the Order.
376 In connection with the Statewide Trash Amendments, the Los Angeles Water Board sent Permittees California Water Code Section 13383 Orders directing Permittees to notify the Los Angeles Water Board regarding how they intended to comply with the statewide trash control provisions. In so doing, Permittees have proposed a variety of implementation strategies (e.g., full capture devices as well as institutional controls), some of which may be effective at removing other pollutants as well and therefore may offset the cost of compliance with the TMDLs.

Source: Los Angeles Water Board analysis of TMDL Staff Reports The TMDL Staff Report Cost Memo includes costs already incurred and costs expected to be incurred over the course of the TMDL implementation periods.

The TMDL Staff Report Cost Memo does not include costs incurred from implementing the six stormwater management program elements, commonly referred to as “minimum control measures” or “MCMs.” Implementation of these requirements can be effective in reducing TMDL pollutants. For example, bacteria discharges can be reduced by implementing the effective prohibition on non-stormwater discharges as required by Clean Water Act section 402(p)(3)(B)(ii) and an illicit discharge detection and elimination program as required by “minimum control measures” established under 40 C.F.R. section 122.26(d)(2)(iv), which could largely, if not entirely, implement bacteria TMDLs, particularly during dry weather. The Order would include these requirements even in the absence of TMDLs, and their costs are therefore not included in the TMDL Staff Report Cost Memo. For purposes of considering Permittees’ cost of compliance, this estimate also does not include monitoring and reporting costs, which are included in Permittees’ annual reported costs presented further below, or costs for non-MS4-related TMDL implementation methods, such as dredging.

The projected cost estimates in the TMDL Staff Report Cost Memo were calculated by adding the costs estimated for each TMDL when they were established, accounting for costs which overlap in order to avoid double

counting. Many BMPs will implement multiple TMDLs at the same time so the cost of the BMP does not need to be included multiple times for each TMDL.

For example, a BMP such as an infiltration project in the Los Angeles River watershed will reduce both bacteria and metals, as required by the Los Angeles River bacteria and metal TMDLs, therefore the cost is represented only once in this cost estimate.

For each watershed, TMDLs with overlapping BMPs and geography were identified, and the TMDL most costly to implement was chosen to represent the set of overlapping TMDLs. Where appropriate, MS4-related costs for the set of overlapping TMDLs were then added to costs of non-overlapping TMDLs implemented in the same watershed. For example, BMPs that implement trash TMDLs were assumed to not affect the progress of meeting other TMDLs. Therefore, for example, in the case of the Los Angeles River Watershed, the cost of implementing the bacteria and metal TMDLs (overlapping TMDLs) were added to the cost of implementing the trash TMDL (non-overlapping TMDL).

The TMDL Staff Report Cost Memo relied on cost estimates as included in the staff reports for Los Angeles Water Board-established TMDLs or the cost estimates as included in the staff reports for Los Angeles Water Boardestablished programs of implementation for U.S. EPA-established TMDLs. In some cases, costs for U.S. EPA-established TMDLs without Los Angeles Water Board-established programs of implementation were represented by an overlapping Los Angeles Water Board-developed TMDL. In other cases, the TMDL was based on “existing conditions,” meaning that pollutant limits were based on existing pollutant concentrations, which were attaining water quality standards, and no additional costs were included in the TMDL Staff Report Cost Memo for that TMDL. When ranges were given for potential costs, the average of the range was used. When multiple implementation options were presented in the TMDL Staff Report, the mid-priced treatment option was chosen, or if only two options were available, the more expensive option was used. For certain TMDLs, where a preferred method of compliance was presented or where a certain compliance option was the overwhelmingly selected option for compliance by MS4 Permittees (e.g., catch basin inserts for trash), the costs of that preferred method were used. All costs were adjusted to 2019 dollars based on the Federal Reserve GDP Implicit Price Deflator.377
d. Method 2: Projected Costs from EWMPs and WMPs

not required to include a financial strategy; therefore, for some individual and group programs implementation cost estimates were not available. In these cases, “NR” is included in the tables below. For Permittees in Ventura County, Watershed Management Programs from similar jurisdictions in LA County were used to project compliance costs.379
i. Los Angeles County Permittees
Of the 87 Los Angeles County Permittees, the majority (83 out of 87380) elected to develop and implement Watershed Management Programs or Enhanced Watershed Management Programs as a compliance pathway for MS4 permit requirements. Of these 83 Permittees, most (80381) have chosen to collaboratively develop and implement these programs. There are 12 Enhanced Watershed Management Programs and 7 Watershed Management Programs that are being implemented by groups of Los Angeles County Permittees. These programs include estimates of the projected costs associated with their full implementation.

For EWMPs, Board staff calculated total costs over a 20-year timeframe, as shown in Table F-29. Most groups presented breakdowns of capital and O&M costs. Some groups reported cost ranges, therefore low and high estimates were calculated. Values were converted to 2019 dollars using the Federal Reserve GDP Implicit Price Deflator. A few EWMPs explicitly reported dollar years, but most did not. For those that did not, staff assumed that the dollar year was the same as the year that the plan was submitted or the year that the most recent plan revision was submitted. Capital costs range from $34.5M for North Santa Monica Bay to $6.5B for Upper LA River. Annual O&M costs range from $1.15M for North Santa Monica Bay to $123.4 for Upper LA River. Total costs for all EWMPs were estimated to be $19.8B to $19.9B in 2019 dollars, undiscounted.

In a presentation to the Los Angeles Water Board on March 2, 2017, the LA River Upper Reach 2 WMP Permittees shared that their order-ofmagnitude estimate for the capital cost of their six regional projects decreased from approximately $210M to $102M after evaluating site conditions. This reduced the overall cost of fully implementing the WMP by one third from approximately $300M to $200M.

The total estimated projected cost for each individual Los Angeles County Permittee participating in one or more of the 19 WMPs/EWMPs is provided where possible in Table F-31. Seven of the 12 EWMPs and three of the eight WMPs reported costs by jurisdiction. If the individual Permittee is an EWMP member, its costs usually comprise capital costs plus 20 years of O&M. Some EWMPs, however, presented capital costs only when they presented their costs by jurisdiction, which is noted in Table F-31. Also noted are WMP costs, which did not present any breakdown between capital and O&M costs. A few WMPs presented an analysis timeframe, which is also noted in Table F-31.

Permittees to develop and implement watershed management programs as a compliance pathway for permit requirements. Therefore, Permittee estimates of projected costs specific to the watershed areas in Ventura County are not generally available. However, Ventura County Permittees have estimated projected costs based on information contained in EWMPs developed in Los Angeles County. The analysis and estimates are presented in a technical memorandum prepared by Larry Walker Associates for Ventura County Permittees, “Preliminary Ventura County MS4 Permit Structural BMP Implementation Cost Estimate,” dated June 1, 2017.

The EWMPs considered include those for the Upper Santa Clara River, Malibu Creek (the portion within Los Angeles County only), Santa Monica Bay J2 and J3, Upper San Gabriel River, and North Santa Monica Bay Coastal Watersheds. According to the technical memorandum, these EWMPs were selected given their similarity to land use characteristics in Ventura County and to capture the various approaches to selecting the EWMP control measures used in Los Angeles County. As described in the technical memorandum, capital costs per acre of urban area treated were extracted from each of these Los Angeles County EWMPs. A series of unit cost summary statistics were computed including average (mean), median, 25th percentile and 75th percentile. The urban MS4 jurisdictional area for each Ventura County Permittee was multiplied by the 25th percentile unit cost and was assumed to represent the low end of the range of anticipated capital costs. Similarly, the urban MS4 jurisdictional area was multiplied by the 75th percentile unit cost and was assumed to represent the high end of range of expected capital costs. Based on this analysis, total projected capital cost estimates range from $272M to $2.0B in 2019 dollars for full implementation through 2040. The total estimated projected cost for each individual Ventura County Permittee is provided in Table F-32.

In addition to costs of implementing structural BMPs, Permittees in Ventura County may incur initial costs to develop WMPs. Los Angeles County and the City of Long Beach have already undergone the development process for EWMPs and WMPs under their permits for 2012 and 2014, respectively. Thus, we present development costs for only Ventura County. Although Ventura County currently does not have any WMPs, the County estimated potential development costs were they to participate in the WMP process, as shown in Table F-35. Costs were inflated to 2019 dollars using the GDP implicit price deflator and assumed to be incurred in the next permit period. Potential development costs were based on the development process in the 2012 Los Angeles County MS4 Permit, which included creating a Work Plan (for EWMPs), preparing a draft WMP or EWMP, and preparing a final WMP or EWMP. Groups were also required to submit Notices of Intent and, in the case of Permittees developing an EWMP, Memoranda of Understanding to the Board at the beginning of the development process. Additionally, Permittees incur costs to develop companion CIMPs. While this process has been streamlined in this Order (e.g., elimination of Work Plan and MOU requirements, reduction in requirements for Notices of Intent), the projected costs were not reduced.

The Ventura Countywide Stormwater Quality Management Program estimated development costs of about $260,000 for smaller, less complex watersheds (Coastal, CCW, and LSCRW) and $680,000 for more complex watersheds (MCW and VRW). Total estimated WMP development costs for Ventura County are $2.14M.

f. Costs of Stormwater Management Program
In addition to the estimates of projected costs for TMDL implementation and projected costs from WMPs and EWMPs, it is generally assumed that Permittees will continue to incur costs similar to or less than those they have reported under Order Nos. R4-2010-0108, R4-2012-0175 and R4-2014-0024 to implement their stormwater management programs’ “minimum control measures” and conduct monitoring and reporting.382 These costs have been reported by Permittees in their Annual Reports and, therefore, are captured by the cost estimates in Table F-36 and Table F-37. For LA County, annual total costs were averaged over three fiscal years, FY16/17-18/19. Over this more recent period, the cost reporting was more consistent across Permittees and reflects the costs, inclusive of enhanced “minimum control measures” in WMPs and EWMPs and CIMPs, almost all of which were approved by FY15/16. For Ventura County, annual total costs were averaged over the term of the prior permit, from FY10/11-FY18/19. Structural BMP costs were removed from the tabulation, as these costs are accounted for in Methods 1 and 2. Due to different cost reporting formats for Ventura County and LA County, capital costs were omitted for Permittees in Ventura County, whereas for Permittees in LA County, costs for Distributed Projects and Green Streets, Regional Projects, and Restoration Projects were omitted. i. Ventura County Permittees: For Ventura County Permittees, these projected annual stormwater program costs are provided in Table F-36 based on the average anticipated budgets reported in the Ventura Countywide Storm Water Quality Management Program Annual Reports during the term of the prior permit (i.e., FY10/11 through 18/19).383 Costs for each year were converted to 2019 dollars using the Federal GDP Implicit Price Deflator then averaged to calculate projected annual costs.

382 For example, instrumenting outfalls with autosamplers is not a recurring activity and was conducted under the prior permits. Additionally, the Order’s minimum control measures provide more flexibility to the Permittees for implementation, relative to the prior permits, allowing Permittees to explore more costeffective and efficient approaches to implementing their stormwater management programs. 383 These estimates were calculated by Los Angeles Water Board staff based on a review of the Ventura County Permittees’ Annual Reports.

g. Summary of total costs estimated from Method 1, Method 2, and Stormwater Management Program Costs
A summary of total cost estimates of complying with the Order is presented in Table F-38 for Method 1 and Table F-39 for Method 2. Costs from Methods 1 and 2 were added to WMP development costs (for Ventura County Permittees) and Stormwater Management Program costs (for all Permittees).

Calculating costs using Method 1, which analyzed structural BMP costs estimated in Staff Reports at the time of TMDL development, yielded a total compliance cost of about $13.4B for structural BMPs. Combined with WMP development and Stormwater Management Program costs, total costs were estimated to be $18.5B. With Method 2, which analyzed structural BMP costs presented in EWMPs and WMPs, total costs ranged from about $21.4B to $25.7B for structural BMPs. Adding WMP development and Stormwater Management Program costs yielded a total cost of $26.5B to $30.8B.

2. Uncertainties in Projected Costs of Compliance
As set forth above, the projected costs, and actual costs, to implement stormwater programs are a significant issue for Permittees. However, it has been, and continues to be, difficult to ascertain the cost at a planning level of fully implementing decades-long stormwater and urban runoff management programs, especially where significant flexibility has been provided to the Permittees to comply both with regard to the manner of compliance and the timeframes for achieving compliance, including permit provisions that allow Permittees to request modifications to both how they achieve compliance and the timeframes for doing so.

There are myriad reasons for this, including but not limited to:

• Innovations in BMPs over time that reduce costs and/or increase pollutant removal;
• Changes in consumer products that reduce or eliminate pollutants in MS4 discharges;
• Limitations of modeling used to identify BMPs that need to be implemented to achieve required water quality outcomes, requiring water quality data for verification/periodic recalibration;
• Imprecise data at the planning stage on site-specific conditions for siting BMPs, which can significantly affect BMP sizing requirements as well as the types of BMPs that can be used at a site; and
• Evolving science and evaluation of local conditions that may support sitespecific water quality objectives. a. Actual Costs: Implementation of Water Quality Improvements Through EWMPs and WMPs
As noted earlier, costs are difficult to reliably estimate at the planning stage.

Data collected thus far from some Los Angeles County Permittees participating in WMPs and EWMPs indicate that these initial planning-level projected costs were sometimes over-estimated. For example, Permittees implementing the Los Angeles River Upper Reach 2 WMP found that sitespecific conditions (namely, infiltration rates) for their regional BMPs were much more favorable than anticipated, allowing them to significantly reduce the BMP footprint size. This, in turn, reduced the estimated cost of their proposed regional BMPs by half from $209M to $102M.386
Several other examples illustrate the same point:
• Ladera Park Stormwater Capture Project (Ballona Creek EWMP): The projected construction cost in the EWMP was $7M, while the actual construction cost was $4.9M, a savings of 30%.387
• Roosevelt Park Stormwater Capture Project (Upper LA River EWMP): The projected construction cost was $33M, while the actual construction cost was $9M, a savings of over 70%.388
• Carriage Crest Stormwater Capture Project (Dominguez Channel EWMP):

The projected construction cost was $8.7M for a BMP capacity of 9 acrefeet. During design, the BMP capacity was increased by threefold to 27 acre-feet. Additionally, the BMP type was modified from an infiltration project to a diversion to the adjacent wastewater reclamation facility. The actual construction cost for the BMP was $15.6M.389 This equates to a reduction in the cost per acre-foot from $967,000 to $578,000. 386 Presentation by CWE and Tetra Tech on behalf of Permittees in the Los Angeles River Upper Reach 2 WMP, “Los Angeles River Upper Reach 2 Watershed Management Area: Watershed Management Program Implementation Status Update,” presented at March 2, 2017 meeting of the Los Angeles Regional Water Quality Control Board. Note that the Permittees had proposed six regional BMPs; given favorable site conditions, the group was able to eliminate one of these BMPs, while still addressing permit requirements.

ATTACHMENT F – FACT SHEET F-344
Permittees also have discretion in deciding how to comply with permit requirements, including requirements to comply with WQBELs and receiving water limitations. What is practicable in one community may not work in another because of differences in population, land use, hydrology, pollution sources, water uses, municipal infrastructure, and community priorities, among other things. For example, as discussed earlier, Permittees participating in the Rio Hondo/San Gabriel River EWMP were prompted to adapt their program to address an error in the initial modeling that overestimated the necessary load reduction for lead, which was identified when reviewing monitoring data, and to be more practicable for their communities by changing the suite of BMPs to be implemented while still addressing permit requirements. These changes reduced the estimated cost by over 90% from $1.4B to $121.7M.390 In other cases, however, site conditions may have been less favorable than anticipated, which can increase the cost. For example, the cost estimate for the Gates Canyon Stormwater Capture Project in the Malibu Creek EWMP was $4.1M, while the actual construction cost was twice that amount at $8.5M. This increase was because the original concept included an infiltration basin but due to geological constraints the project was modified to a water harvesting system with emergency bypass dry wells.391
Furthermore, some EWMPs present assumed land acquisition costs in their cost functions that equate to $5.6M-$6.1M per acre for BMPs installed on private parcels392, which would not need to be incurred if Permittees engage in public-private partnerships as municipalities elsewhere in the U.S. have begun doing within the last several years (further discussed in Part XIII.D.2.d of this Fact Sheet). This would result in substantial cost savings. b. Difficulties in Estimating Costs
Many of the disparities between estimated and reported costs such as those described above are due to the difficulties in reliably estimating costs at the planning stage. Additionally, as noted earlier, reported costs of compliance for the same program element can vary widely from permittee to permittee. To date, standardized methods to estimate the costs of stormwater pollution reduction approaches, particularly on a watershed or subwatershed scale, have not been developed. While there are appropriate grounds for differences among MS4 permits, differences of a very wide margin are not easily explained.393 As noted, some cost estimates have been over-reported. In other 390 Rio Hondo/San Gabriel River Water Quality Group, “Rio Hondo/San Gabriel River Revised Watershed Management Program,” May 17, 2019. It is noted that $379M of the original cost, about 30%, was attributable to EWMP implementation in the City of Azusa, which discontinued its participation in the revised WMP.

392 Ballona Creek, Malibu Creek, Upper LA River, Upper Santa Clara River assumed a land acquisition cost of $129 per square foot, or $5.6M per acre. Upper San Gabriel River assumed a land acquisition cost of $139.01 per square foot, or $6.1M per acre.

cases, costs are reported that Permittees would have incurred regardless of their MS4 permit requirements. Not all reported program costs are solely attributable to compliance with requirements of the MS4 permit. Many program components, and their associated costs, existed before the first MS4 permits were issued in the 1990s. A 2005 State Water Board study found that certain reported costs included activities that provide separate and additional municipal benefits such as street sweeping and storm drain and channel cleaning and that the inclusion of these activities and their associated costs was not uniform across municipalities. These costs along with others like solid waste/litter collection costs are not solely or even principally attributable to MS4 permit compliance since these practices have long been implemented by municipalities. Also, some stormwater control measures may be integrated into multi-benefit projects serving many objectives (e.g., a public park whose mowing maintenance schedule is designed to maximize stormwater retention). Other measures may start out as stormwater control measures only to become expected by residents for their other benefits (e.g., dog waste bags at public parks). Therefore, the program cost related to complying with MS4 permit requirements is often some fraction of the total reported costs.

The State Water Board study also noted inherent limitations in the cost data quality. The most significant data quality limitation cited is that the costs provided by the municipalities were not sufficiently detailed or referenced to provide opportunity for independent review of the accuracy and completeness of the cost data. Similarly, the costs presented in the prior MS4 permits in the Los Angeles Region were not presented with supporting data or references so that they can be independently reviewed. Los Angeles Water Board staff often had to seek additional information and clarification from Permittees regarding their reported costs.394
Note that these issues were evaluated in detail in the 2012 Los Angeles County MS4 Permit Fact Sheet and in the State Water Board study. A key finding of the State Water Board study was that a significant portion (greater than 50%) of the costs attributed to stormwater compliance activities also provides additional municipal benefits.395 The remainder of program costs was either pre-existing or resulted from enhancement of pre-existing programs.396 The County of Orange found that an even lesser amount of program costs was solely attributable to MS4 permit compliance, reporting that the cost attributable to implementation of its Drainage Area Management Plan is less than 20 percent of the total budget. The remaining 80 percent is attributable to pre-existing programs.397
Despite these problems, the Board has endeavored to estimate the possible range of costs of compliance with the Order, including WQBELs as presented in Part XIII.D.1 above.

c. Improvements in Cost Estimation & Reporting
There are several initiatives in progress to address the challenges of accurately quantifying and reporting the costs to implement stormwater programs, including an effort undertaken by the State Water Board’s Office of Research Planning and Performance (ORPP)398 to provide guidance on estimation of costs to implement TMDLs and consistent tracking and reporting by municipalities of costs of permit compliance. The Environmental Finance Center (EFC)399 at California State University, Sacramento recently compiled existing resources on stormwater infrastructure costs and developed suggested guidance to explain best practices for estimating costs. EFC’s effort evolved from the State Water Board study in 2005 and includes estimates of costs for permit compliance activities, technical resources that assist stormwater managers, and project costs for both green and grey infrastructure.

ORPP’s guidance describes methods for obtaining information on compliance approaches and associated costs and for completing an independent analysis of costs. The guidance strives to promote greater consistency and transparency related to estimation of costs to implement TMDLs. ORPP notes that, even with improved guidance, precise cost estimation remains challenging and the level of precision possible may be low in many cases. For example, industry-wide, there is no uniform database of projects’ components and costs to date.

ORPP’s guidance as well as the EFC’s initiative and others are improving the basis for cost reporting by municipalities and, as a result, the Water Boards’ consideration of economics in issuing permits. Los Angeles Water Board staff has participated in developing the ORPP guidance and has provided input on the EFC’s initiative, and has considered this information when drafting the Order and associated reporting requirements in Attachments E (Monitoring and Reporting Program or MRP) and H (Annual Report Form). Using this guidance, section 2 (Program Expenditures) of Attachment H requires that all Permittees report costs in a uniform manner based on clearly defined program categories and cost elements. See, also, Table 2.2 in Attachment H. d. Increasing cost-effectiveness through public-private partnerships Estimated compliance costs as presented in this Fact Sheet are based on current and past compliance methods. However, Permittees in the Los Angeles region could use relatively new financing and contracting mechanisms that fall under the umbrella of pay-for-performance, a form of public-private partnership, to contribute towards meeting MS4 requirements more cost-effectively while also implementing multi-benefit green infrastructure on private property without needing to acquire private land, which a number of local jurisdictions in the U.S. have done.

performance models, also known as pay-for-success, incentivize contractors to find private properties on which to construct green infrastructure, leading to more distributed stormwater capture and benefits, as well as lower costs and faster project timelines than traditional BMP implementation. For example, Philadelphia’s Green Acres Retrofit Program encourages contractors to develop portfolios of multiple projects, spreading out risk, and property owners can reduce their stormwater fee if they accept a project on their property.

Another example is Prince George’s County’s Clean Water Partnership, a community-based public-private partnership that prioritizes local minorityowned contractors and develops a local workforce specializing in green infrastructure. These municipalities have used public-private partnerships to supplement gray stormwater infrastructure with green infrastructure, which could also reduce the need for gray infrastructure. By adapting elements of existing public-private partnerships from other parts of the U.S., Permittees in the Los Angeles region have opportunities to green urban landscape and meet MS4 requirements more quickly, cost-effectively, and in the manner that works best locally.

Public-private partnerships can be more cost-effective than traditional stormwater BMP implementation for several reasons. Public-private partnerships structured under a pay-for-performance model shifts risk from municipalities to private partners.400 While details of specific pay-forperformance models established by different municipalities vary, municipalities essentially pay private contractors for outcomes, such as when BMPs promised to capture a certain amount of stormwater are successfully completed. Municipalities are not involved in the specific design and management of the BMPs. Municipalities may choose to pay only after construction completion, or they may make payments at certain stages of construction. They may also structure payment models to pay contractors for operations and maintenance over certain time intervals if BMPs are shown to still be effective over those time intervals. In addition, because municipalities would solicit bids from multiple parties, this fosters competition and increases cost-effectiveness. For example, Prince George’s County saved more than 40% on costs compared to traditional procurements.401 And Philadelphia pays a maximum of $90,000 per acre on private land in its Greened Acre Retrofit Program, compared to the $250,000-$300,000 per acre for green infrastructure on public land, a savings of 64%-70%.402 Public-private partnerships could also achieve faster BMP construction due to the nature of being located on private property. There would be fewer administrative steps compared to BMP implementation on public land. Also, projects on private property are more likely to be smaller, simpler projects that could be completed much faster than intensive, major projects on public 400 Environmental Incentives. 2017.

property that require specialized equipment and expertise. Furthermore, there is significantly more land that is private than public. Encouraging public-private partnerships would open up many more available locations for BMPs.

Public-private partnerships can be structured in a way to prioritize certain areas for green infrastructure and steer employment towards communities who need it most. Private properties with more impervious surface already present greater opportunity for green infrastructure installation, and higher levels of impervious surface are often correlated with lower levels of neighborhood income, so contractors would already find more green infrastructure opportunities in lower-income neighborhoods. In Los Angeles County, where property owners are subject to the Measure W parcel tax, the opportunity to reduce the tax could be an incentive for property owners to accept the installation of green infrastructure on their property, particularly for lower-income property owners. However, municipalities can offer further incentives, paying more for projects located in neighborhoods with higher need, as was done in a stormwater credit trading program in Washington, D.C.403 Municipalities can also offer to pay more for local and/or minorityowned contractors, as was done in Prince George’s County, where greater than 80% of contracts went to local minority-owned businesses. This would provide areas with the greatest need, i.e. low-income, often non-white, and disproportionately impacted by the COVID-19 pandemic, with opportunities for green jobs and greener neighborhoods.404

3. Sources of Funding for Permittees and Potential Impacts to Funding Sources Due to COVID-19 and Recovery Efforts
Permittees are required to secure the resources necessary to meet the requirements of the Order, including those necessary to achieve the receiving water limitations and WQBELs. As discussed elsewhere in the Fact Sheet, these permit provisions are required by federal regulations. That said, the Los Angeles Water Board recognizes that in light of the recession caused by the COVID-19 pandemic, local governments around the country are facing significant challenges in financing and constructing stormwater management infrastructure required by the CWA and federal NPDES regulations. However, as of May 2021, the number of vaccinations completed continues to rise both in the region and around the country, and the Biden administration has proposed trillions in new infrastructure spending on top of the $1.9 trillion dollar American Rescue Plan effective in March 2021, all of which improve the outlook for stormwater funding.

The pandemic brought extraordinary hardship, and it hit society unequally. The unemployment rates in Los Angeles and Ventura Counties in the spring of 2020 hit highs of 18.8% and 14.5%, respectively.405 Low-income residents experienced 403 Parrish, Janet. 2018.

higher rates of unemployment than middle- and high-income residents, many of whom were able to work remotely and more easily avoid becoming infected by COVID-19.406 Jobs disappeared in leisure, hospitality, and entertainment, on which Los Angeles County relies heavily. The agricultural industry in Ventura County was also hit hard, and on average received less federal aid compared to growers in other parts of the country.407 Due to systemic inequities, COVID-19 has disproportionately hit African Americans and Latinos nationwide.408 This has occurred in Los Angeles as well, in addition to disproportionate impacts on the local Pacific Islander population.409 Before the pandemic, Permittee municipalities where these underserved communities comprise a significant portion of their populations already had constrained opportunities for revenue generation due to lower average incomes and tax bases.410 Existing disadvantages in resources have been exacerbated by the pandemic because underserved communities bear a heavier burden in healthcare costs and deaths. In Los Angeles, areas with high poverty had almost four times the death rate on average than areas with low poverty.411 Furthermore, African Americans and Latinos were more likely to be laid off or furloughed because of the pandemic.412
Despite the real hardships, at the macro level economic suffering was not as bad as feared in early predictions. As of May 2021, during the course of the pandemic, the federal government has put more than $5 trillion into the economy.413 Congress passed the American Rescue Plan, which extended unemployment benefits, sent stimulus checks to the public, and sent $350 billion to state and local governments, with stormwater infrastructure being one of the many intended uses of this funding.414 President Biden has also ordered that 40% of benefits from federal climate action go to underserved communities as part of the Justice40 initiative.415 406 Chetty, Raj, John N.

As of May 2021, predictions are that the California 2021-2022 budget will have a surplus of $38B-$75B.416 Economists in 2021 have consistently revised their outlooks to be more optimistic, expecting unemployment to return to pre-pandemic levels in 2022.417 As of March 2021, the unemployment rates in Los Angeles and Ventura Counties were 10.9% and 6.4%, respectively.418 While this is a significant improvement compared to the early months of the pandemic, there is still a ways to go to full recovery. At the local level, Los Angeles property tax revenues from the past year were higher than expected, and it is likely that funding for Measure W will remain largely intact.419 Los Angeles County is set to receive $1.9 billion, and the city of Los Angeles is set to receive $1.4 billion from the American Rescue Plan.420 These amounts are greater than LA County and the city of Los Angeles’s previously projected budget deficits of $935 million and $750 million, respectively.421 While the specific magnitude of the effect on municipal revenues is unclear as of May 2021, there will be continued or increased funding of state and federal grants that can be used towards stormwater projects. There has been increased spending by the general public as more people have received vaccinations and the economy has continued to reopen, which will increase local tax revenues.

The pandemic’s economic impacts largely affect general funds, which present a limited and less reliable source of revenue. Permittees are compelled more than before to identify alternative sources such as fees, assessments, grants, and loans.

In the past, municipalities throughout the State have been successful in securing alternative funding for stormwater services through fees, assessments, or special taxes, as well as through developer fees, and gas taxes.422 Many Permittees have takes-executive-actions-to-tackle-the-climate-crisis-at-home-and-abroad-create-jobs-and-restorescientific-integrity-across-federal-government/ 416 Walters, Dan. 2021.

For example, U.S. EPA estimated household willingness to pay for improvements in freshwater quality to support fishing and boating to be $182 to $242 per year (adjusted for inflation using Bureau of Labor Statistics on-line CPI Inflation Calculator). (National Pollutant Discharge Elimination System – Regulations for Revision of the Water Pollution Control Program Addressing Storm Water Discharges, Final Rule. Federal Register 64 (8 December 1999): p. 68793. Web. 20 June 2019.) This estimate can be considered conservative, since it does not include important considerations such as the benefits to marine waters, wildlife, or flood control. California State University - Sacramento’s 2005 study corroborates U.S. EPA’s estimates, reporting annual household willingness to pay for statewide clean water to be $240 (adjusted for inflation using Bureau of Labor Statistics on-line CPI Inflation Calculator).

also taken steps to establish a stable funding source, which will help fund stormwater projects despite the current economic downturn. The following Parts XIII.D.3.a-e provide examples of these efforts. Part XIII.D.3.f of this Fact Sheet provides examples of state and federal grants and loans. a. Los Angeles County Safe, Clean Water Program
In November 2018 Los Angeles County gained voter approval of Measure W, a special parcel tax of 2.5 cents per square foot of impermeable surface that will raise up to $285 million annually to capture and clean up stormwater.

Measure W required approval by a two-thirds majority to pass. The tax will help cities across Los Angeles County comply with the Order. It will also help make the region more water resilient in the face of drought and climate change, particularly in underserved communities that are often hit harder by environmental and public health stresses.423
Of the annual revenue, forty percent will be returned to the municipality of origin to create new local projects and programs and fund operation and maintenance. Table F-40 provides the estimated “local return” revenues that will be allocated to Los Angeles County Permittees based on the estimated annual revenue of $285M. It is anticipated that a total of $112.6M will go directly to municipalities through the local return.

The remaining ten percent of the annual revenues would be allocated to the Los Angeles County Flood Control District for administration of the program and other district water quality projects and programs.

The Los Angeles County Department of Public Works has evaluated the planning-level projected costs for full implementation of some of the Watershed Management Programs and Enhanced Watershed Management Programs, and the anticipated revenue from the Safe, Clean Water Program for corresponding watershed areas relative to the WMP/EWMP milestones.

The preliminary working draft of their analysis suggests that, without any additional sources of funding and assuming the accuracy of the projected costs, significant additional time will be needed to meet most milestones.

However, the projected costs used by the Los Angeles County Department of Public Works were higher than values from the Board staff analysis, presented above, and in many cases Permittees have succeeded in significantly lowering these projected costs at both a program scale and project scale.

Additionally, as discussed below, Permittees have, and can continue to, leverage additional funds through partnerships with other entities and securing grants and/or low-interest loans.

In summary, the passage of Measure W, with nearly 70% of the vote in LA County, suggests strong support for improved water quality. The revenue generated will go toward funding the Permittees’ WMPs and EWMPs, thereby significantly assisting in compliance with the Order.
b. Los Angeles County’s Measure A
Los Angeles County voters in November 2016 approved Measure A, the Safe, Clean Neighborhood Parks and Beaches Measure, to support local parks, beaches, open space, and water resources with an annual parcel tax of 1.5 cents per square foot. The measure received overwhelming support, with the approval of 75% of voters. The county’s Regional Park and Open Space District disburses the funding through grant programs, divided over multiple categories of projects. Category 3, the Protecting Open Space, Beaches, and Watersheds Program, has about $7.4M annually for competitive grants. The program considers projects that capture stormwater and protect drinking water and waterbodies, as well as projects that provide multiple benefits, such as increasing recreational opportunities, protecting habitats, and improving public health.425
c. Culver City’s Measure CW
During the November 8, 2016 Special Municipal Election, over two thirds of Culver City residents voted in favor of Measure CW, the Clean Water, Clean Beach Parcel Tax. Single family residential parcels are taxed $99 annually, while each multi-family residential dwelling unit is taxed $69 annually. Each parcel owner of a non-residential property is taxed $1,096 per acre of land (or portion thereof) annually. The $1,096 is pro-rated for non-residential parcels less than one acre. Charges first appeared on the tax statements in fall 2017. Funds raised by Measure CW will be used for improvements in water quality in Ballona Creek, Marina del Rey, and Santa Monica Bay. Measure CW is expected to generate about $2 million per year, beginning in fall 2017. All Measure CW money will be used in Culver City to improve water quality through measures such as low-flow diversions, multi-benefit stormwater capture projects, green streets, and trash controls, among others.

Measure CW was directly designed to pay for Culver City’s cost of compliance with the Order, including Culver City’s responsibilities in implementing programs and projects in the Ballona Creek and Marina del Rey EWMPs in which it is participating.426
d. Ventura County’s Benefit Assessment Program
The Ventura County Watershed Protection District Benefit Assessment (BA) Program, which levies property fees, is authorized by the Ventura County Watershed Protection District Act, as amended by Chapter 438, Statutes of 1987 and Chapter 365, Statutes of 1988. The FY2019 Benefit Assessment for Watershed Protection is based on the rates established for Fiscal Year 1997.

Those same rates were approved for Fiscal Years 1998-1999 through 2017- 2018.

f. State and Federal Funding Sources
Public agencies, both federal and state, recognize the importance of stormwater improvement projects. This section describes some sources of funding from grants and loans that have been provided in the past and will be provided in the future to help offset the costs of stormwater management and leverage ongoing funding sources such as those described above. The variety of grant programs that can support stormwater projects highlights the opportunities for creativity in incorporating stormwater BMPs into other infrastructure and community development projects, which will not only help achieve stormwater goals, but also open more avenues of funding.

Permittees in the Los Angeles Region have been receiving significant State funding through grant programs and interagency agreements with the California Department of Transportation, and so far there is no official indication that they will not continue doing so as several State-wide stormwater grant programs are expected to proceed in coming years. All Permittees have completed a Stormwater Resource Plan (SRP) or equivalent and have obtained concurrence on the SRP or equivalent from the State Water Board, making all Permittees eligible to compete for State funds to support additional stormwater projects identified in the SRP or equivalent.

Since 2012, Permittees have received $186.1M in state funding for 42 projects that will support Permittees’ compliance with the Order. Specifically, between 2012 and 2015, Los Angeles County and Ventura County Permittees have received $25.5M from Proposition 84 and the Drought Response Outreach Program for Schools (DROPS) for 18 projects. This funding covered over 70% of the total cost of the 18 projects. In 2016, Permittees received $51M of Proposition 1 grant funding during Round 1 for 13 projects. The Proposition 1 grant funding is covering over 50% of the total cost of the 13 projects. In February 2021, $18.6M was awarded to Permittees for five projects from Prop 1 Round 2 funding. Since 2012, Los Angeles County Permittees have also received over $91M in funding from the State through Cooperative Implementation Agreements with the California Department of Transportation for 6 projects.

Permittees have also been awarded Prop 68 funding and may continue to compete for additional grant funding. According to the California Department of Fish and Wildlife, grants will not be canceled, and unspent funds will not be taken back by the state during the COVID-19 pandemic.427 In March 2020, the California Department of Parks and Recreation awarded about $54 million from Proposition 68’s Statewide Park Program to Los Angeles County jurisdictions to develop new parks, multi-use paths, and improve existing facilities.428 In addition, in 2020 the California Natural Resources Agency awarded $18.5 million for multi-benefit green infrastructure investments in or benefiting disadvantaged or severely disadvantaged communities through Proposition 68’s Green Infrastructure Grant Program.

Potential sources of future grant funding from state and federal programs are shown in Table F-45. In addition to Proposition 68 programs, a number of federal grant programs can be used to build stormwater infrastructure while also promoting economic development, resilience to climate change-induced hazards, green transportation alternatives, and urban greening.429 This highlights the increased funding opportunities that could come with projects that creatively incorporate stormwater BMPs. Some programs explicitly address the longstanding problem of underserved communities having greater need for green infrastructure but having fewer resources by explicitly prioritizing underserved communities, such as Proposition 68’s Statewide Park Program, the USDA Forest Service Urban and Community Forestry Program, and Economic Development Administration’s Public Works and Economic Adjustment Assistance programs

Moreover, loan options with below-market interest rates are available for stormwater projects, as shown in Table F-46. The Clean Water State Revolving Fund can finance a wide variety of stormwater projects, with repayment beginning one year after completion of construction and a maximum repayment period of 30 years. In November 2020, U.S. EPA invited California to apply for $500 million in Water Infrastructure Finance and Innovation Act (WIFIA) loans through the new state infrastructure financing authority WIFIA (SWIFIA) program.430 This would provide additional funds to the State Revolving Fund upon approval. The California Infrastructure and Economic Development Bank, or IBank, offers loans for a wide variety of infrastructure projects under its Infrastructure State Revolving Fund, including water projects, parks, streets, and many other types of infrastructure that can incorporate stormwater BMPs. IBank also supports water conservation and infrastructure projects through its Statewide Energy Efficiency Program.

Furthermore, IBank offers subsidies to borrowers in communities with high unemployment and/or low median household income. Municipalities are also eligible for loans under the U.S. Department of Housing and Urban Development’s Section 108 Loan Authority. Amounts are available in amounts up to five times a municipality’s Community Development Block Grant, and funded projects can incorporate stormwater infrastructure.

In conclusion, the Los Angeles Water Board recognizes that the costs of compliance with the Order are significant and that many Permittees have limited resources to implement actions to address their MS4 discharges.

However, there are also a number of funding options that Permittees can pursue to assist with compliance. Based on a consideration of the cost of compliance, as discussed above, the Board has structured the permit as flexibly as possible to give Permittees the opportunity to sequence actions to address the highest water quality priorities; options to demonstrate compliance; the ability to customize their control measures; sufficient time to comply (in many cases decades from the time the TMDL was established); opportunities to request time extensions based on economic factors among others; and the ability to collaborate and pool their resources to implement programs and projects to achieve compliance and to also collaborate and pool their resources to monitor their compliance.

4. Environmental and Societal Costs of Not Controlling MS4 Discharges Economic considerations of stormwater and urban runoff management programs tend to focus on costs incurred by municipalities in developing and implementing the programs. This is appropriate, since as discussed above, these costs are significant and present a challenge for Permittees. However, as far back as 2000, the Water Boards recognized that it is also important to consider the costs of water quality impairment; that is, the negative impact of pollution on the economy and the positive impact of improved water quality (see, for example, Order WQ 2000- 11). So, while it is important to consider the cost of compliance, it is also important to consider the costs that would be incurred by not fully regulating or controlling MS4 discharges to receiving waters. Southern California’s local economy thrives on a healthy environment, as does the health of its population. Failure to regulate discharges from the Los Angeles Region’s MS4 will result in greater pollution of the rivers, streams, lakes, reservoirs, bays, harbors, estuaries, coastal shorelines

County spent an all-time high of $21.9 billion in the region.”431 Many of those tourists visit the beaches and on average, over 129 million beach visits occur each year in Southern California.432 A study that looked at beach attendance and bathing rates in Southern California approximated that, depending on the season, 26% to 54% (on average 45%) of the beach attendees have physical contact with the coastal waters.433 Urban runoff in southern California has been found to cause illness in people swimming near storm drains.434, 435 One study of recreational exposures in marine water impacted by MS4 discharges following storm events in San Diego County estimated gastrointestinal illness risks at 1.2 illnesses (based on epidemiological study) and 1.5 illnesses (based on quantitative microbial risk assessment) per 1000 wet weather recreation events (surfing).436 Another study of south Huntington Beach and north Newport Beach found that an illness rate of about 0.8 percent among bathers at those beaches resulted in about $3 million each year in health-related expenses.437 Extrapolation of such numbers to the beaches and other water contact recreation in the region could result in significant expenses to the public and to public health, while improvements in coastal water quality could result in a reduction of gastrointestinal illness locally and a concurrent savings in expenditures on related health care costs.

Likewise, stormwater runoff from MS4 discharges can significantly impact ocean water quality – and this, in turn, affects public health and the economy. The County of Los Angeles Public Health recommends “beach users … avoid contact with ocean water for a period of 3 days after significant rainfall, especially near flowing storm drains, creek and rivers”.438 Rain advisories can have a significant impact on the region’s coastal economy. According to an estimate by Pendleton and Kildow (2006), the non-market value of a beach day is worth between $15-$50, or about $19-63 in 2019 dollars, to the average beach visitor in California.439 These values 431 Easter, Makeda. “California Tourism Industry Grows for the 7th Straight Year, Report Says.” Los Angeles Times, 9 May 2017, https://www.latimes.com/business/la-fi-ca-economic-impact-20170504- story.html

represent how much someone is willing to pay just for enjoying a day at the beach, not including travel and parking costs. Considering the popularity of Southern California beaches, the economic impact of each beach posting/closure day could be significant. Atiyah, et al. (2013) found that beaches in Santa Monica Bay and Malibu that installed storm drain diversions had an average increase in beach attendance of 610,324 visits per year compared to beaches without storm drain diversions, holding all other factors constant.440 As an illustrative example of the potential increase in monetized benefits to beach visitors resulting from installing storm drain diversions, multiplying the value of an average California beach day by the change in attendance yields annual benefits ranging between $11.6 and $38.5 million at the average beach in 2019 dollars. Changes in water quality not only affect benefits for beachgoers, but also for local businesses that depend on sales from beachgoers, as well as municipalities that rely on sales tax revenues.

The average visitor to the beach spent about $30 for each day visit in 2001, or about $43 in 2019 dollars, at local businesses (excluding gas and auto expenditures).441 This would mean that for the average beach with storm drain diversions, nearby businesses receive about $26.2 million in additional annual revenue from beach visitors compared to beaches without storm drain diversions, holding all other factors constant. In addition, beach postings negatively affect local home values, potentially as far as several kilometers away.442 Failure to regulate MS4 discharges will therefore result in great costs and foregone benefits to the regional economy.

5. Benefits of Stormwater Capture and Management
As set forth above, California Water Code section 13241 requires a consideration of economics; it does not require a “cost benefit analysis.” While a rigorous quantitative “cost benefit analysis” is not required and may not be possible, the costs of not controlling MS4 discharges – and the benefits that result from controlling MS4 discharges – are both relevant to the ultimate cost of compliance.

This is because the costs of compliance may be offset by the benefits of stormwater and urban dry weather runoff management, which broadly include improvements in water quality, augmentation of local water supplies, increased economic benefits, enhancement of beneficial uses, and increased employment and income.

Accordingly, a discussion of some of the additional benefits from controlling MS4 discharges is included here.

As an initial matter, it should be noted that there are significant economic benefits (some of which are quantifiable, and some which are not) from stormwater management. A 2004 study conducted by USC/UCLA that assessed the costs and benefits of implementing various approaches for achieving compliance with MS4 permits in the Los Angeles Region found that non-structural systems would provide $7.42B in benefit, adjusted to 2019 dollars. If structural systems were determined to be needed, after adjusting to 2019 dollars, the study found that total benefits 440 Atiyah, Perla, Linwood Pendleton, Ryan Vaughn, and Neil Lessem. “Measuring the effects of stormwater mitigation on beach attendance.” Marine Pollution Bulletin. 72.1 (2013): 87-93. 15 July 2013.

could reach $23.9B.443 Monetized benefits in this study accounted for a number of benefits – reduced need for flood control, increases in property values, additional groundwater supplies, public willingness to pay for avoided stormwater pollution, cleaner streets, improved beach tourism, preservation of ecosystem services in the marine coastal zone, and cost savings from reduction of sedimentation in local harbors. However, recreational and public health uses were not quantified in this study, and much has changed in the Los Angeles Region since 2004, including an increase in population. Therefore, the benefits value is likely higher than $23.9B. a. Recreational and Public Health Benefits
As an example of a portion of recreational and public health benefits that can accrue from implementing the MS4 permit, we can examine the Los Angeles River, on which multiple entities have conducted research as part of revitalization efforts. Improving water quality at the river is crucial in transforming the river into an amenity that would attract residents and visitors, and the Upper LA River EWMP has stated that certain revitalization projects are key candidates for future integration with the EWMP process. Currently only portions of the river are being utilized for recreation. If the entire river could have the same amenities as a park in terms of being a location where people could walk, exercise, enjoy the outdoors, view wildlife, and engage in water recreation, the potential benefits would be significant. There are about 728,000 working adults who live or work within one mile of the Los Angeles River.444 The Trust for Public Land found that about 43% of adults in Los Angeles visited parks, trails, and recreation centers between 2015 and 2016, and that the average frequency of these visits was 1.13 times per week, or 59 times per year. Their analysis found that the average value for each visit was $3.04, adjusted to 2019 dollars.445 Assuming that the same proportion of adults living and working near the river would go to a newly revitalized Los Angeles River for recreation, this would yield annual recreational benefits of $55.9M. Furthermore, the public health benefits would be substantial. The difference in average annual medical care costs between active (those who do moderate to vigorous exercise) and inactive adults ages 18-64 is $1,242 in 2019 dollars446, and 24% of LA residents use parks as their primary place for exercise.447 Although this percentage could potentially increase with the addition of more park space and a revitalized LA River, applying this percentage to the number of adults living and working nearby the LA River 443 Devinny, Joseph S., Sheldon Kamieniecki, and Michael Stenstrom. “Appendix H: Alternative Approaches to Stormwater Control.” NPDES Storm Water Cost Survey Final Report.

yields annual health benefits of $217M. These benefits values represent only a portion of potential total benefits, as the population value only comprises working adults and not children, seniors, or unemployed adults. Further research that includes seniors would likely result in substantial additional public health benefits, as the average annual medical care cost difference between an active and inactive person 65 and over is about $2,490 in 2019 dollars, double the value for adults under 65.448
Installing green infrastructure would also deliver public health benefits by mitigating urban heat island effects, with greater returns on investment for installations located in inland areas lacking tree canopies and green spaces, which also tend to be lower-income and often non-white. 449 In urban areas,
buildings and pavement retain heat, making them hotter than surrounding non-urban areas, known as the urban heat island effect. Climate change will continue to exacerbate urban heat island effects, but they can be mitigated by pursuing urban greening practices. Nature-based solutions that incorporate trees and vegetation can decrease local temperatures, particularly if they are distributed throughout an area. Reduced temperatures during hot weather not only makes it more comfortable for people to recreate outside, but it can also save lives during extreme heat waves. De Guzman et al. (2020) found that relative to the average mortality rate, during an average five-day heat wave in Los Angeles County there are 4.1% more deaths on the first day and 11.9% more deaths on the fifth day.450 Using these results, they found that if Los Angeles County had tree coverage at 40%, as opposed to the baseline of 16%, during a September 2010 dry Santa Ana event there would have been a 29% reduction in mortality, equivalent to saving 23 lives. While the study only modeled mortality, it can reasonably be expected that hospitalizations and health conditions brought on by heat stress would be reduced with lower extreme temperatures as well. In addition to trees, other green infrastructure such as bioswales, rain gardens, and green roofs can also reduce temperatures.451 In metropolitan areas nationwide, neighborhoods with lower median household incomes are associated with less urban tree cover.452 In areas where the federal government historically redlined, current average 448 The Trust for Public Land. 2017, May.

b. Water Supply Cost Savings and Co-Benefits
Stormwater capture is an effective way for Permittees to achieve the goals of the CWA and the requirements of this permit by preventing the stormwater and associated pollutants from reaching receiving waters. Stormwater capture has also become the focus of intense interest in the wake of California’s most recent 2012-2019 drought. The Water Boards have recognized the importance of treating stormwater as a valuable resource where capture and use can result in water supply cost savings, as well as multiple other benefits within a watershed. Among other efforts, the State Water Board’s Strategy to Optimize Resource Management of Stormwater (STORMS) seeks to promote stormwater capture and use. STORMS’ recent 2018 report Enhancing Urban Runoff Capture and Use points out that among a variety of benefits, “stormwater capture can also reduce reliance on imported water from distant sources, which reduces inter-basin (or inter-region) transfers and polluted runoff. Stormwater supports the fit-for-purpose water supply concept by satisfying less sensitive water demands, such as certain household, landscaping, and commercial needs, with mildly polluted water. Runoff from roads and driveways can be captured and harvested locally using distributed hybrid systems (for example, bioretention with an underdrain that feeds a cistern used for irrigation) configured to provide non-potable water for human use.” 454
The Order supports investment towards infrastructure for groundwater recharge to create a resilient local water supply. The potential for water usage from stormwater is significant, with Diringer et al. (2020) from Pacific Institute estimating that stormwater capture from paved surfaces and rooftops in urbanized Southern California and the Bay Area could add 420,000-630,000 acre-feet in average annual water supply, or about 6-10% of annual water usage in those areas in 2014.455 According to Porse et al. (2018), Los Angeles County “receives 55-60% of its annual water supplies from imported sources, which include northern California through the Sacramento-San Joaquin Delta, the Colorado River Basin, and the higher-altitude Owens Valley.”456 The authors found that even after accounting for full-cycle costs, which include costs for all stages from the capture to end-use of water, stormwater capture can still be cheaper than importing water. Imported water costs around $1,476-$1,790 per acre foot, whereas the cost for existing large stormwater capture is $995 per acre foot. As for proposed new large stormwater capture 453 Hoffman, Jeremy S., Vivek Shandas and Nicholas Pendleton. 2020.

projects, including converting flood control infrastructure for multipurpose use, agencies in Los Angeles estimated total costs per acre foot ranging from $1,110-$2,727.457 The Southern California Water Coalition examined costs for 32 stormwater projects implemented across Southern California and found an even wider cost per acre foot range of $59 to more than $250,000 per acre foot, with a median of $1,070. They found that projects that can annually capture larger amounts of stormwater have a lower cost per acre-foot, and costs differ by project type. Median costs for distributed projects were $25,000 per acre foot, new centralized projects were $6,900 per acre foot, and retrofit projects were $600 per acre foot.458 Cost ranges from these studies ($59- $250,000/acre foot) are both lower and higher than the imported water cost range ($1,476-$1,790/acre foot), indicating that while stormwater projects costs can be more expensive, in many cases they may not need to be, particularly when agencies can think of creative stormwater solutions.

The Order gives Permittees the flexibility to develop multi-benefit stormwater management projects that will improve water quality while also providing benefits such as recharging of groundwater basins for local water supply and implementation of Low Impact Development (LID) policies and green streets policies. Regulating MS4 discharges would not only lead to water supply cost savings for residents, but also environmental, public health, and recreational benefits resulting from reduced stormwater pollution. Shimabuku et al. (2018) from Pacific Institute emphasizes that effective urban stormwater capture provides an opportunity for addressing multiple benefits including flood control, water quality impairments, improving water supply reliability, providing habitat, reducing urban temperatures, reducing energy use, creating community recreation spaces, and increasing property values.459 Diringer et al. (2020) conducted an analysis of stormwater capture project costs and benefits as they affect the cost of an acre-foot of water. They found that failing to consider the effects of co-benefits results in inflated net project costs. They gathered data from rounds 1 and 2 of Prop 1E and Prop 84 project proposals. Of a total of fifty projects, or 26 addressed urban runoff and 24 dealt with non-urban runoff. Most of the urban runoff projects the researchers considered were in Southern California. The authors found that after accounting for the projects’ benefits, the net levelized cost for urban stormwater capture projects decreased from $1,030 per acre foot to $150 per acre foot, with some projects even yielding net benefits. Monetized benefits considered in their calculation include flood damage reduction, water quality, energy savings, community recreations, public use, property values, habitat value, CO2 equivalents, and avoided costs. Because many projects reported limited benefits categories, the overall net cost per acre foot would likely be even lower than $150 when other co-benefits are considered.

There are a number of projects under development to recharge the region’s basins. One such project was recently completed, the Piru Groundwater Basin 457 Ibid.

recharge project, which will capture stormwater from 123 acres in the Ventura County unincorporated area of Piru. This project will result in approximately 25 AFY recharge to the basin.460 The Tujunga Spreading Grounds Enhancement Project is a collaborative project between the Los Angeles Department of Water and Power and the Los Angeles Flood Control District that will enhance the 150-acre Tujunga spreading grounds. This project will double the facility’s recharge capacity and deliver 4 billion gallons of recharge to the groundwater basin and result in an increase in groundwater recharge to the San Fernando Groundwater Basin, increasing local water supply.461 Furthermore, green street projects provide an opportunity for stormwater management to serve multiple benefits such as flood control, groundwater replenishment, pollutant removal, and create aesthetic green spaces for the local community. In the City of Los Angeles, Avalon Green Alley, a green street project, creates “1.8 acres of improved art and alleys and green alleys in a 35 acre neighborhood”.462 The green street project provides “stormwater retrofits in two alley segments including permeable pavers, dry wells and infiltration trenches that harvest rainwater flowing from a 6.04-acre subtributary to the Los Angeles River” and “is designed capture and infiltrate 1,381,608 gallons of stormwater into underground aquifers annually”.463 Similar green street projects have been implemented in Ventura County such as in the Government Center’s parking lot by means of pervious concrete gutters. Continuing such improvements under the MS4 permit would provide benefits from flood control, improved water quality, and cost savings from reduced imported water.
c. Ecosystem Services Benefits
In addition to the foregoing, Permittees and their residents will accrue various other environmental benefits resulting from the Order. For example, the 2018 STORMS report describes a range of benefits of capture and use, suggesting that “designing stormwater infrastructure to directly support ecosystems broadens the traditional approach to stormwater management. In this broader sense, retained stormwater can be put into soil where soil biota, macrophytes, and stream interflow systems improve water quality and ecosystems supported by baseflow or high groundwater. Ecosystem benefits include habitat improvement, increased food sources, carbon sequestration, pollutant uptake, reduced ozone (Nowak 2006), and reduced heat-island effects from plant growth. Improved baseflow results in decreased water temperatures and prolonged dry weather flows, and increased amounts and types of soil biota will aid in carbon sequestration and pollutant uptake (Klaus 2015). Local stormwater capture can also lead to energy-saving schemes that (1) capture water before it becomes contaminated with the pollutants on streets and in sewers; (2) rely on energy efficient processes for removing contaminants; (3) treat water only to the extent necessary for intended use (fit-for-purpose 460 Ventura County Storm Water Capture for Groundwater Recharge - Construction Project, http://bondaccountability.resources.ca.gov/Project.aspx?ProjectPK=19812&PropositionPK=48 461 Stormwater Engineering Division: Tujunga Spreading Grounds Enhancement Project, https://dpw.lacounty.gov/wrd/Projects/TujungaSG/index.cfm 462 “Avalon Green Alley Network Project.” Parkology,

water); and (4) obviate the need for diversion and large, centralized, energyintensive treatment and distribution approaches.” 464 d. Other Benefit Considerations
The Pacific Institute and the University of Santa Barbara’s Bren School of Environmental Science and Management elsewhere framed the topic of moving towards multiple benefit approaches for water management. The organizations plan to develop a systematic framework for identifying and incorporating the costs and benefits of water management strategies into decision making. They find a broader consideration of benefits associated with water management decisions will achieve broader project support, avoid unintended consequences, optimize resources, and cost sharing, and increase transparency. 465
Such a framework would support a more robust consideration of potential economic benefits of stormwater management projects not considered in the Board’s economic analysis, such as:
• Reduced frequency, area, and impact of flooding - Stormwater capture BMPs that reduce runoff volumes and consequently flood volumes. The decrease in potential damage due to flooding provides economic benefit. • Reduced cost of public infrastructure - On-site volume control with stormwater BMPs can downsize or eliminate stormwater conveyance infrastructure and provide public cost savings.
• Reduced pollution and water treatment costs and improved water quality - The reduction in runoff volume reduces erosion and pollutant delivery, thereby reducing the downstream costs of water treatment. The resulting improvements in water quality, stream channel stabilization, and aesthetics can also increase the value of riparian properties and increase utility of recreational visitors. The increased infiltration gained from stormwater BMPs can improve and sustain stream base flow conditions in some areas to better maintain downstream habitat. 466
• Increased property values where green infrastructure and LID projects are implemented.

Other studies, too, have described the importance of co-benefits derived from proper stormwater management. For example, analysis for the San Diego Region Bacteria TMDLs found the contribution of co-benefits (non-bacteria water quality benefits) such as property value, riparian habitat and treatment of other water pollutants provide more than half of the total economic benefits.467 In a series of studies listed in a report created by the U.S. EPA in 2013, the benefit-to-cost ratios of four LID/GI projects in Sun Valley were listed. All four projects showed a benefit-to-cost ratio of greater than 1 464 State Water Resources Control Board, Division of Water Quality, “Enhancing Urban Runoff Capture and Use,” STORMS Projects 1a and 1b, April 10, 2017.

indicating that, over the 50-year evaluation period, the benefits of these projects are higher than their cost.468
The Los Angeles Water Board assumes many of the benefits described in this section accrue to Permittees and their communities as a result of implementing their stormwater programs. The Board expects further program improvements, resulting from implementation of actions required by the Order, to increase benefits over time.

For example, the Order promotes:
• Employment and stimulus in the local economy, which are especially crucial during this recession caused by COVID-19. Economic Roundtable conducted a study in 2011 that found that job stimulus for every $1 million invested in water efficiency projects was greater than traditional Los Angeles industries such as motion picture production and new home construction. The study found that 12.6 to 16.6 annualized jobs in recycled water, groundwater, stormwater, graywater systems, and water conservation projects were created for every $1 million invested in these types of projects. The study also showed that approximately 74% of money invested in stormwater projects at the time of the study was spent locally, on businesses located within Los Angeles County. Furthermore, every million dollars invested in stormwater projects in Los Angeles stimulated an estimated $1.99 million in total local sales due to multiplier effects of investing in the local economy. For example, cities pay people to work on stormwater projects, who then spend their incomes on housing, goods, and services.469 Building on the findings by Economic Roundtable, Los Angeles Alliance for a New Economy estimated that over 30 years, the Safe, Clean Water Program (Measure W) will create about 6,530 construction jobs and 1,347 O&M jobs, as well as about 1,559 annual indirect and induced jobs. This would yield about $14B in overall regional economic benefits from $9B in investment. Furthermore, many of these jobs created would be good-paying jobs that do not require an advanced degree, accessible to those in disadvantaged communities.470 Sustained increases in these occupations depend on Los Angeles’ continued investment in water use efficiency projects.
• Use of nature-based solutions to mitigate and treat stormwater (e.g. implementation LID and GI regional projects). This technique alleviates the load on the existing stormwater conveyance infrastructure and reduces potential maintenance costs, while reducing localized flooding issues. • Utilization of stormwater as a valuable resource to replenish our groundwater basins or for direct reuse. Imported water makes up approximately 70 to 75% of Southern California region’s water supply, with local groundwater, local surface water, and reclaimed water making up the remaining 25 to 30%.

Ventura County will increase by 2% and 2.6%, respectively. This population increase will be accompanied by an increase in water consumption. This increase will require larger volumes of imported water, which will be associated with higher costs. With stormwater used as a resource to replenish local groundwater basins, local reliance on imported water can be reduced, thereby controlling the costs incurred from importing water. A report prepared by the City of Signal Hill and Richard Watson & Associates states that the Metropolitan Water District forecasts water rates (Tier 1 rates for fully treated water) to increase from $794/acrefoot ($/AF) in 2012 to $910/AF in 2015 and $1,115 in 2020.

6. Conclusions
The Los Angeles Water Board has considered economics in issuing the Order and the specific requirements therein.

This consideration includes estimates of the possible range of costs of compliance with the Order, including the WQBELs, considering the likely and proposed means of compliance. It also includes the costs to the environment and society of not controlling MS4 discharges as well as the economic benefits of controlling MS4 discharges, including through stormwater capture. The range of costs of compliance as presented in Part XIII.D.2, Table F-38 and Table F-39 is $21.3B to $31.4B over 20 years. Even considering the highest cost in this range, the Board finds that the requirements in the Order are necessary to ensure the reasonable protection of beneficial uses. This is because these cost estimates are associated with implementation of permit requirements to achieve water quality objectives that were set at the levels necessary to provide reasonable protection of beneficial uses. These water quality objectives were either established by the U.S. EPA or approved by the U.S. EPA pursuant to CWA section 303(c). In most cases, the water quality objectives are those necessary to protect aquatic life and public health-related beneficial uses. The fundamental objective of the federal CWA, as set forth in section 101(a)(2), is “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters” and to achieve water quality that provides for the protection and propagation of fish, shellfish, and wildlife and provides for recreation in and on the water. The NPDES Program, including the MS4 NPDES Program, is one of the principal regulatory tools for achieving this objective. The requirements in the Order also consider the magnitude and uncertainty in projected costs and include provisions to help defray these costs (e.g., allowances for time extensions).

Because of the difficulty in accurately projecting the cost of compliance with the Order as presented in the discussion above, and given that permit requirements extend decades into the future, the Los Angeles Water Board has incorporated provisions for adaptive management of programs as new information is gained as well as provisions that allow Permittees to request extensions for milestones based on technical, operational, and economic factors. The Los Angeles Water Board has also acknowledged that it can consider revisions to TMDLs including their schedules and final deadlines, where it determines it is appropriate, and then reflect those changes in the permit. Finally, the Board has acknowledged the currently available dedicated sources of funding for MS4 permit compliance, including the Benefit Assessment Program in Ventura County and the Safe, Clean Water Program in Los Angeles County, among others, and that it will consider how these

funds are allocated to priority projects to meet upcoming deadlines when considering any requests for extensions.

The Los Angeles Water Board has also provided the Permittees significant flexibility to choose how to implement the Order. The Order allows the Permittees the flexibility to address critical water quality priorities, namely discharges to waters subject to TMDLs, but aims to do so in a focused and cost-effective manner while maintaining the level of water quality protection mandated by the Clean Water Act.

The Permittees can customize their control measures and choose to implement the least expensive measures that are effective in meeting the requirements of the Order. The Order also does not require the Permittee to fully implement all requirements within a single permit term. Where appropriate, the Board has provided Permittee with additional time outside of the permit term to implement control measures to achieve final WQBELs and Receiving Water Limitations.

Cost savings from customizing programs and shifting resources accordingly are also possible. The Permittees’ affirmative steps to secure funding are noteworthy, and some other potential sources of funding are identified in the Board’s economic considerations. However, the discussion of potential sources of funding is far from exhaustive. There are myriad opportunities to leverage funding; for example, Permittees could pursue low-interest loans through the State Revolving Fund that would allow access to greater sums of money needed in the near term for capital costs and pay these off over time with the ongoing revenues from dedicated funding sources. Additionally, there are a number of interrelated Propositions, including Measures W471, H472, A and M473 (“WHAM”), addressing stormwater/water resiliency, affordable housing, parks, and transportation, respectively, that can be creatively combined to implement multi-benefit stormwater projects. Finally, partnerships beyond the Permittees themselves should be more fully explored.

Some Permittees have effectively tapped into funding or other in-kind resources from the California Department of Transportation, as mentioned above; private entities such as commercial businesses; and schools. However, this opportunity is far from fully utilized.

Stormwater capture is an effective way for Permittees to achieve the goals of the CWA and the requirements of this permit by preventing the stormwater and associated pollutants from reaching receiving waters. As noted above, the specific benefits of stormwater capture have also become the focus of intense interest in the wake of California’s most recent 2012-2019 drought. The Water Boards have recognized the importance of treating stormwater as a valuable resource where capture and use can result in multiple benefits within a watershed. This consideration identifies benefits to the environment, people and the economy and clearly demonstrates the value of effective management of stormwater quality. 471 Measure W led to the passage of the Safe Clean Water Program, described earlier in this section of the Fact Sheet.

Having considered economics along with the other factors in section 13241, the Los Angeles Water Board has also provided the Permittees with time to implement control measures to achieve interim and final WQBELs and Receiving Water Limitations. This time has been provided in various ways, including through compliance schedules that are consistent with the schedules of implementation established in TMDLs pursuant to California Water Code section 13242, compliance schedules proposed by Permittees and approved by the Los Angeles Water Board through Watershed Management Programs and Enhanced Watershed Management Programs for pollutants not addressed by TMDLs, and time schedule orders, where justified, for WQBELs and Receiving Water Limitations with final compliance deadlines that have passed. The Los Angeles Water Board is committed to continue to evaluate the costs of compliance as permit requirements are implemented and, as noted above, has included provisions that allow Permittees to request extension of deadlines, where warranted.

E. The Need for Developing Housing Within the Region
According to the U.S. Census, between April 1, 2010 to July 1, 2018, Los Angeles County and Ventura County experienced an estimated population increase of 2.9% and

3.3%, respectively.474 An increase in population creates a demand for more housing.

Based on data from the California Department of Finance, both Los Angeles and Ventura counties have been experiencing an increase in population and housing units since 2010.475 An increase in population creates a higher demand for water, exacerbates usage of natural resources, and increases generation of waste and pollution. In order to conserve and protect the quantity and quality of our natural resources, development must be done systematically. To protect human health and the environment, create economic opportunities, and provide attractive and affordable neighborhoods, U.S. EPA encourages smart growth and low impact development.476 Stormwater management is an essential smart growth strategy. According to U.S. EPA, using smart growth and low impact development strategies, communities and developers can reduce runoff quantity, protect water quality, and conserve water by developing compactly, preserving ecologically critical open space, and using green infrastructure strategies.477
Improved stormwater management may also help reduce the region’s historic reliance on imported water to meet population needs. For over 100 years, this region has relied on imported water to meet many of our water resource needs. Imported water makes up approximately 70 to 75% of the Southern California region’s water supply, with local ground water, local surface water, and reclaimed water making up the remaining 25 to 474 United States Census Bureau.

30%.478 The Los Angeles Region imports approximately 50% of its water supply.

Untreated MS4 discharges collect and transport pollution to our waterbodies and detrimentally affect their beneficial uses. However, when properly managed, MS4 discharges can be used as a resource.

The Order also helps address the water needs associated with the need for housing by controlling the quality and quantity of MS4 discharges and using it as a water resource for recycling and re-use. The low impact development (LID) requirements of the Order emphasize the necessity to balance growth with the protection of water quality. LID emphasizes cost effective, lot-level strategies that replicate the natural hydrology of the site and reduce the negative impacts of development. By avoiding the installation of more costly conventional stormwater management strategies and harnessing runoff at the source, LID practices enhance the environment while providing cost savings to both developers and local governments.

The Order also supports an integrated water resources approach that manages water resources by integrating wastewater, non-stormwater, stormwater, recycled water, and potable water planning through the capture and beneficial use of MS4 discharges on a regional scale. An integrated approach can preserve and augment local groundwater resources thereby reducing imported water needs and increasing local water resiliency.

Local water resiliency increases the region’s capacity to support increases in population and the accompanying need for housing.

F. The Need to Develop and Use Recycled Water
During the terms of the 2012 Los Angeles County, 2014 City of Long Beach, and 2010 Ventura County MS4 permits, California experienced a severe drought which lasted 376 weeks, starting from the year 2011 to 2019. The U.S. Drought Monitor characterizes the drought based on specific criteria where D4 is defined as exceptional drought, in which widespread crop and pasture losses and shortages of water create water emergencies.

Per the U.S. Drought Monitor, “[t]he most intense period of drought occurred the week of July 29, 2014 where D4 affected 58.1% of California land.” 479 Along with the drought, Los Angeles and Ventura counties experienced wildfires, floods, extreme heat and more, which strained the region’s resources and highlighted infrastructure inefficiencies.

In contrast to the drought, the 2019 water year had above average rainfalls and in some cases even breaking daily rainfall records.480 Due to climate change, the region will only continue to experience more extreme weather events.

Furthermore, as mentioned in Part XIII.E above, which considers the need for developing housing within the region, according to the U.S. Census, between April 1, 2010 to July 1, 2018, the populations in Los Angeles County and Ventura County rose by 2.9% and 3.3%, respectively. This increase in population leads to an increase demand for water supply to meet the needs of the residents. Most of the water supplied to Los Angeles County is imported from the State Water Project, Colorado River, and 478 Southern California Association of Governments.

the Los Angeles Aqueduct.481 Ventura County relies on local groundwater as well as imported water.482 The interconnected effects of water quality and the health of our communities is also becoming increasingly apparent. Water shortages and the pumping of groundwater at a rate that depletes groundwater supply further demonstrates the need to develop a robust strategy that incorporates recycled water to build resiliency to the region’s most pressing issues, while being protective of public health and the environment.

Initiatives for water resiliency have passed at the state and local levels. At the state level, in April 2015, Governor Brown issued Executive Order B-29-15, which outlined actions needed to respond to the severe drought, including mandated reductions in urban potable water usage by 25% statewide. In April 2019, Governor Newsom issued Executive Order N-10-19, ordering key agencies, including the California Environmental Protection Agency, to prepare a water resilience portfolio that meets the needs of California’s communities, economy, and environment through the 21st century.483 The draft portfolio includes a number of recommendations related to making stormwater capture a growing share of local water supply.484 At the local level, the City of Los Angeles developed L.A.’s Green New Deal, which includes plans to recycle 100% of its wastewater by 2035 as well as source 70% of all water locally by 2035 and capture 150,000 acre-feet per year (AFY) of stormwater.485 In Ventura County, the Integrated Regional Water Management Plan was developed in 2014, in which the Watersheds Coalition of Ventura County is responsible for the implementation and planning at a regional level. Through this planning effort, Ventura County has leveraged its resources through collaborations with local agencies and organizations, and grant funding in order to implement multi-benefit projects.486 Along with government recognizing the water challenges the region is facing, residents also recognize the need to develop recycled water infrastructure and the importance of water resiliency with the passing of Measure W in Los Angeles County, which provides a dedicated funding source for multi-benefit stormwater capture projects through a parcel tax on impermeable areas.487 Historically, stormwater has not been considered a viable component of the regional water portfolio. However, if stormwater is captured and treated, a new resource could be added to local water supply and numerous benefits could be achieved. These include:
• Regional reduction in reliance on imported water;
• Aid in the restoration of area aquifers both from a supply and water quality point of view;
• Reduction in the need for extensive public works projects; and 481 The Future of Integrated Regional Water Management in Los Angeles County. http://www.resources.ca.gov/docs/LA_County.pdf.

• Improvement in the quality of impaired water bodies.

Municipalities across the region are now acknowledging the importance of recognizing stormwater as a resource and thus conducting watershed-based planning to implement multi-benefit solutions for stormwater management. Consistent with the Clean Water Act, which supports the implementation of stormwater management at a watershed scale, the 2012 Los Angeles County MS4 Permit and the 2014 City of Long Beach MS4 Permit contained provisions to allow for the abovementioned benefits to be achieved through the implementation of approved Watershed Management Programs. The Order further expands such provisions to Permittees in Ventura County. Watershed Management Programs allow Permittees the flexibility to implement requirements of the Order on a watershed scale through customized strategies, control measures, and BMPs to achieve multi-benefit solutions. Participation in a Watershed Management Program is voluntary and allows the Permittee to address the highest water quality priorities in consideration of particular socio-economic, land use, and geographic characteristics.

In addition, participation in Watershed Management Programs allows Permittees to consider the potential amount of dry weather urban runoff and precipitation and thus the amount of non-stormwater and stormwater available to capture. The exact volume of stormwater available for capture is dependent on the intensity and duration of storm events. Looking at land uses across the region and applying land use-specific runoff coefficients, the Los Angeles and San Gabriel Rivers Watershed Council estimates that, on average, about 601,000 acre-feet/year of runoff are discharged from the Los Angeles Region to the Pacific Ocean.488 The average annual rainfall in Ventura County is about 18 inches and has a total area of 1,843 square miles.489 It is not possible to capture all MS4 discharges; however, a significant portion could be captured and put to beneficial use. Capturing stormwater from a larger portion of the watershed could increase the volume of this “new” water even further.

Larger projects (and the corresponding savings) are also possible. The County of Los Angeles recharges stormwater already. While the scale of these recharge activities is limited compared to the volume of water potentially available to recharge, the value of the process is significant. For example, in 2000 “County conservation efforts captured 220,000 acre-feet of local stormwater runoff that was valued at $80 million dollars.”490 The unknown effects of infiltrating stormwater to recharge groundwater have created some concern that such activities could introduce pollutants to the water supply.

However, these concerns are likely overstated. The U.S. Bureau of Reclamation has found:

Based on the findings of the WAS research, decentralized stormwater management would provide a local and reliable supply of water that would not negatively impact groundwater quality. A decentralized approach could contribute up to 384,000 acre-feet of additional groundwater recharge annually if the first ¾” of each storm is infiltrated on all parcels, enough to provide water annually to approximately 1.5 million people. The value of this new water supply would be approximately $311 million, using the MWD Tier 2 rate for 2010.

Recent studies in the urbanized area of Los Angeles County have also shown that in the process of infiltration through the soil, many contaminants are removed with no immediate impacts, and no apparent trends to indicate that stormwater infiltration will negatively impact groundwater.492 Moreover, in groundwater basins with elevated concentrations of salts, utilizing recycled stormwater, which has low concentrations of salts, to recharge the aquifers may actually improve water quality. The value of this is difficult to quantify but is an additional benefit.

The Order addresses the need for recycled water by emphasizing stormwater capture for beneficial use as a means to control the discharge of pollutants from the MS4 to surface waters. The Order also supports the diversion of non-stormwater to wastewater reclamation facilities where it can be treated for beneficial reuse. State law and policy advocates greatly expanding the use of recycled water to help meet local demand and reduce the volumes of water that are imported from other regions. Increased utilization of recycled water will require looking beyond the traditional reclaimed wastewater and will require utilizing stormwater and non-stormwater that is wasted by conveyance in the MS4 to the ocean. Stormwater capture and use has not featured as prominently as municipal wastewater in the discussion of water recycling but is increasingly acknowledged as a valuable asset for augmenting local water supply. The use of recycled water can be accomplished in direct (such as irrigation projects) or indirect (such as infiltration) ways. Both direct and indirect methods can be completed on a variety of different scales. To maximize the benefits available from using recycled water, the direct and indirect projects will need to be completed on household, neighborhood, watershed, and regional scales. There is a growing number of projects in the region that can serve as examples of what may be accomplished through the development and implementation of recycled water projects.

Some successful examples of onsite stormwater capture are being demonstrated by TreePeople.493 TreePeople’s demonstration projects range from small scale rainwater harvesting at single family home locations, to large scale watershed projects. At Tuxedo Green in Sun Valley, TreePeople redesigned the intersection with a flood control system that conveys most stormwater under, instead of into, the busy intersection. The water is stored in a 45,000-gallon cistern to be used for irrigating the landscaping at the new pocket park, which is planted with native and drought-tolerant species.

Another state of the art project was implemented by the City of Santa Monica called the Santa Monica Urban Runoff Recycling Facility (SMURRF).494 The project harnesses the urban runoff (primarily during the dry season) and treats it for various pollutants to create a source of high quality water for reuse in landscape irrigation, thus reducing the need 492 Los Angeles and San Gabriel River Watershed Council. 2005.

for potable water. Because the facility captures the dry weather runoff before it reaches the Santa Monica Bay, it decreases a significant amount of pollutants from negatively impacting the Bay and associated beaches. The SMURRF is also open to the public and has several exhibits to raise public awareness of Santa Monica Bay pollution and the role of each individual in the watershed’s health.

The County of Los Angeles Department of Public Works, Watershed Management Division has targeted the Sun Valley Watershed “…to solve the local flooding problem while retaining all stormwater runoff from the watershed, increasing water conservation, recreational opportunities, wildlife habitat, and reducing stormwater pollution.”495 This aggressive plan involves several stakeholders and has implemented a variety of on-site BMPs as well as stormwater infiltration retrofits and diversions.

In Ventura County, the Ventura Countywide Stormwater Quality Management Program has implemented various stormwater quality improvement projects and BMPs. In the City of Moorpark, College View Dog Park diverts all stormwater to infiltration basins and can retain 100% of the water during average rainfall periods. Walnut Acres Park has both on-site and off-site infiltration capability. The City of Ventura implemented downtown parking lot retrofits including curb cuts, bioswales, and permeable pavers and have applied similar features for green street projects.496 A notable green street project was implemented at the Ventura County Government Center. This project implemented an innovative infiltration system through the installation of 4,805 linear feet of pervious concrete gutters to capture stormwater from the Government Center’s parking lot. The captured stormwater is filtered through an infiltration trench that flows into dry wells for groundwater recharge. Furthermore, in the Ventura River Watershed, Happy Valley Bioswale was designed to mimic natural processes to remove pollutants in stormwater runoff. This filtration system includes a baffle box at the entrance which removes trash, sediments, and small particles and is followed by a natural soil and plant filtration system to further treat the stormwater and allows for a thriving habitat.497 With the issuance of the Order, stormwater capture projects such as the abovementioned will allow for further expansion on a watershed scale and create consistency within the region.

In addition, there are a number of Total Maximum Daily Loads (TMDLs) established by the Los Angeles Water Board that incorporate recycled water programs as potential implementation actions to meet TMDL requirements. These potential actions focus on both traditional water recycling and the newer stormwater recycling approaches. Such recycled water programs reduce reliance on potable water supplies by expanding water recycling and aiding in the reclamation of poor quality, unconfined groundwater supplies. The capture, treatment and use of stormwater could augment these techniques as well. On-site capture of stormwater helps prevent the water from being contaminated by urban by-products to begin with and the use of this high-quality resource could reduce the unnecessary use of potable water for non-potable needs. 495 http://www.sunvalleywatershed.org/watershed_management_plan/wmp-0ES.pdf. 496 Ventura Countywide Stormwater Quality Management Program, Presented on September 13, 2018 https://www.waterboards.ca.gov/losangeles/water_issues/programs/stormwater/municipal/watershed_ management/workshops/docs/VCWPD_20180913_RB_PermitRenewal_FINAL-1.pdf. 497 Happy Valley Bioswale, uninc.vcstormwater.org/projects/happy-valley-bioswale.

XIV. STATE MANDATES
Article XIII B, section 6(a) of the California Constitution provides that whenever “any state agency mandates a new program or higher level of service on any local government, the state shall provide a subvention of funds to reimburse that local government for the costs of the program or increased level of service.” No provision of the Order constitutes an unfunded state mandate subject to subvention under Article XIII B, section (6)(a) of the California Constitution.

A. Renewal of the Permits Is Not a New Program Or Higher Level of Service As a threshold matter, MS4 permitting is not a “program” as that term is used in Article XIII B, section (6). The California Supreme Court has defined a “program” for purposes of Article XIII B, section 6, as: (1) programs that carry out the governmental function of providing services to the public, or (2) laws which, to implement a state policy, impose unique requirements on local governments and do not apply generally to all residents and entities in the state. (San Diego Unified School Dist. v. Commission on State Mandates (2004) 33 Cal.4th 859, 874 (reaffirming the test set forth in County of Los Angeles v. State of California (1987) 43 Cal.3d 46, 56); Lucia Mar Unified School District v. Honig (1988) 44 Cal.3d 830, 835.)
An NPDES permit for MS4 discharges arises from the Clean Water Act, which forbids everyone – individuals, businesses, state governments, tribal governments, local governments, etc. – from discharging pollutants from point sources to waters of the United States without an NPDES permit. (33 U.S.C. §§ 1311(a), 402, 502(5); see also 40 C.F.R. §§ 122.21, 122.22, 123.25.) The Clean Water Act requires permitting of private and governmental (federal, state, and local) sources of stormwater and nonstormwater alike. (33 U.S.C. § 1342(p); 40 C.F.R. § 122.26.) The Permittees here must have a permit because they discharge pollutants, not because they operate an MS4.

See, County of Los Angeles v. State of California (1987) 43 Cal.3d 46, 58 ([“Although local agencies must provide benefits to their employees either through insurance or direct payment, they are indistinguishable in this respect from private employers. In no sense can employers, public or private, be considered to be administrators of a program . . . .”].) All polluters, whether private or public, must get a permit. (See, e.g., City of Richmond v. Com. on State Mandates, (1998) 64 Cal.App.4th 1190, 1199 (new law made “the workers’ compensation death benefit requirements as applicable to local governments as they are to private employers,” and therefore did not impose a new program or higher level of service.)
To be sure, the permit conditions provide a public benefit, but that is not the same thing as providing services to the public. There is a critical distinction between a law or executive order that requires local governments to provide a public service, and one that address the conduct and happens to cover local governments – and other entities such as private industry – because they engage in the conduct. This principle is best illustrated by County of Los Angeles v. Department of Industrial Relations (1989) 214 Cal.App.3d 1538. There, the Department of Industrial Relations enacted statewide safety regulations that governed all public and private elevators. (Id., at pp. 1540–1541.) The county argued that the regulations created a mandatory, reimbursable “program” because “all passenger elevators in all county buildings are necessary for the performance of peculiarly governmental functions . . . .” (Id., at pp. 1545–1546, italics omitted.) Rejecting that argument, the court explained that “the critical question is whether the mandated program carries out the governmental function of providing services to the public, not whether the elevators can be used to obtain these services.”

ATTACHMENT F – FACT SHEET F-381
(Id., at p. 1546, italics omitted.) In other words, a state law providing that local governments have to comply with the same safety rules as everyone else does not constitute a state mandated “program.” The same is true here. The Permit does not require Permittees to operate an MS4. Rather, it implements a body of state law that provides that, if a local government operates an MS4, it must take steps to mitigate pollutant discharges, like all other polluters. The fact that the specific permit here is issued to local governments does not render the permit a program that carries out a “governmental function” particular to local government or a permit that imposes unique requirements on the local governments.

Even if an MS4 permit could be considered a “program,” the requirements of the Order do not constitute a new program or a higher level of service as compared to the requirements contained in the previous permits issued by the Los Angeles Water Board to the Permittees. The overarching requirement to impose controls to reduce the pollutants in discharges from MS4s is dictated by the Clean Water Act (33 U.S.C. § 1342(p)(3)(B)) and is not new to this permit cycle. The inclusion of new and advanced measures as the MS4 programs evolve and mature over time is specifically anticipated under the Clean Water Act (55 Fed. Reg. 47990, 48052 (Nov. 16, 1990); 61 Fed. Reg. 43761 (Aug. 26, 1996); USEPA “Interim Permitting Approach for Water Quality Based Effluent Limitations in Storm Water Permits,” EPA 833-D-96-001 (September 1996)) because the experience gained in implementation of existing permits and ongoing technological developments help direct appropriate adaptation of the programs to better address pollution. Such new and advanced measures refine existing measures to improve the effectiveness of the ongoing program and do not constitute a new program or higher level of service. And while the new or advanced measures may result in additional costs to the Permittees, resulting new costs is not the test for a higher level of service. “If the Legislature had intended to continue to equate ‘increased level of service’ with ‘additional costs,’ then the provision would be circular: ‘costs mandated by the state’ are defined as ‘increased costs’ due to ‘an increased level of service,’ which, in turn would be defined as ‘additional costs.’” (County of Los Angeles v. Com. on State Mandates (2003) 110 Cal.App.4th 1176, 1191, quoting Workers’ Compensation Mandates Decision, supra, 43 Cal.3d. at p. 55.)
B. The Permit Requirements Fall Under Several Exceptions to Mandates Rules Even if some of the requirements imposed on the Permittees with this renewal could be considered a new program or higher level of service, the following exceptions to a finding of unfunded mandates preclude subvention here:

1. The permit provisions are required by the federal Clean Water Act and implementing regulations:

One of the exceptions to the subvention requirements is that, if the mandate imposes a requirement that is mandated by a federal law or regulation and results in costs mandated by the federal government, no subvention is required unless the statute or executive order mandates costs that exceed the mandate in that federal law or regulation. (Gov. Code, § 17556(c).) The Order implements federally mandated requirements under the federal Clean Water Act and implementing regulations and its requirements are therefore not subject to subvention of funds.

This includes federal requirements to: (i) effectively prohibit non-stormwater discharges through the MS4 to receiving waters; (ii) reduce the discharge of pollutants in stormwater to the maximum extent practicable; (iii) include such other provisions as the permitting authority (here, the Los Angeles Water Board)

determines appropriate for the control of such pollutants; (iv) attain applicable TMDL wasteload allocations; and (v) conduct monitoring and reporting.

Non-stormwater discharge prohibition: Federal law requires that an MS4 permit effectively prohibit non-stormwater discharges through the MS4 to receiving waters. (33 U.S.C. § 1342(p)(3)(B)(ii).) The Order’s requirements to achieve the effective prohibition of non-stormwater discharges are thus compelled by federal law.

TMDL requirements: The Clean Water Act requires TMDLs to be established for waterbodies that do not meet federal water quality standards. (33 U.S.C. § 1313(d).) The Clean Water Act also requires that MS4 permits include “such other provisions as the Administrator or the State determines appropriate for the control of [] pollutants.” (33 U.S.C. § 1342(p)(3)(B)(iii).) U.S. EPA interprets this provision to mandate “controls to reduce the discharge of pollutants to the maximum extent practicable, and where necessary water quality-based controls.”498 Once U.S. EPA or a state establishes a TMDL, federal law requires that NPDES permits must contain water quality-based effluent limitations (WQBELs) consistent with the assumptions and requirements of any applicable wasteload allocation. (40 C.F.R. § 122.44(d)(1)(vii)(B).) Indeed, TMDLs are developed for the purpose of specifying requirements for the achievement of water quality standards in impaired waters (33 U.S.C. § 1313(d); 40 C.F.R. § 130.7) The Order’s requirements for attainment of TMDL wasteload allocations are therefore compelled by federal law.

Several generations of the MS4 permits issued in California have prohibited discharges that cause or contribute to exceedances of water quality standards in the receiving water. TMDL provisions, including WQBELs, simply add a process for meeting this requirement, generally based on a compliance schedule.

Monitoring and reporting requirements: Federal law requires that NPDES permits incorporate monitoring and reporting provisions. (33 U.S.C. §§ 1318(a); 1342(a)(2); 40 C.F.R. §§ 122.26(d)(2)(i)(F); 122.41(h), (j)-(l); 122.42(c); 122.44(i); 122.48.) The Order’s monitoring and reporting requirements are thus imposed pursuant to federal law.

Maximum Extent Practicable (MEP) standard: The Clean Water Act mandates that the Order “require controls to reduce the discharge of pollutants to the maximum extent practicable.” (33 U.S.C. § 1342(p)(3)(B)(iii).) Department of Finance v.

Commission on State Mandates (2016) 1 Cal.5th 749, as modified on denial of rehearing (Nov. 16, 2016) (Department of Finance) analyzed whether the Clean Water Act’s MEP standard required four particular provisions concerning trash receptacles and inspections in the 2001 Los Angeles County MS4 permit. In concluding that the provisions were not required by federal law, the Supreme Court stated that, “[h]ad the Regional Board found when imposing the disputed permit conditions, that those conditions were the only means by which the maximum extent practicable standard could be implemented, deference to the board’s expertise in reaching that finding would be appropriate.” (Department of Finance, supra, 1 Cal.5th at p. 768.) The Supreme Court further stated that “[s]uch findings 498 Phase I Stormwater Regulations, Final Rule, 55 Fed. Reg. 47990, 47994 (Nov. 16, 1990) (emphasis added); see also Building Industry Ass’n of San Diego County v. State Water Resources Control Bd. (2004) 124 Cal.App.4th 866, 882-887; Phase II Stormwater Regulations, Final Rule, 64 Fed. Reg. 68722, 68737.

are “case specific, based among other things on factual circumstances.” (Id., fn.

15.)
To be entitled to deference, regional water boards must make an express finding that the particular set of permit conditions finally embodied in a given permit is required to meet that federal standard and must support that finding with evidence.

The Los Angeles Water Board expressly finds that the Order specifies requirements necessary for the Permittees to reduce the discharge of pollutants in MS4 discharges to the MEP. Parts IV and VIII establish program requirements for Stormwater Management Program Minimum Control Measures, including programs for public information and participation, industrial and commercial facilities, construction activities, planning and land development, public agency activities, and illicit discharge detection and elimination, among others pursuant to 40 CFR section 122.26(d)(2)(iv). The requirements of these programs represent structural and non-structural water quality control measures that are effective, technically feasible, and generally accepted as appropriate.

Part IX establishes elective program requirements related to Watershed Management Programs (WMP), which provide an alternative compliance path through the preparation of a WMP that allows the Permittees to prioritize water quality issues and propose the specific control measures to address the prioritized issues and achieve the receiving water limitations and numeric WQBELs in accordance with a time schedule. This allowance also provides Permittees with ample flexibility to select, in a customized fashion, the water quality control measures that will reduce pollutants in stormwater to the maximum extent practicable.

The Los Angeles Water Board finds that the programmatic requirements of the Order are necessary to meet the MEP standard. The mix of program elements reflects the necessary pollutant reduction expected by the demanding federal MEP standard, but also represents a balancing of competing interests such as effectiveness, regulatory compliance, public acceptance, cost, and technical feasibility. To the extent there may be multiple means of achieving pollutant reductions and that there could be trade-offs between program areas with potentially higher costs and greater pollutant reductions, the permit programs are structured to provide the optimum reduction of pollutants necessary to reduce pollutants to the maximum extent practicable. This finding is the expert conclusion of the principal state agency charged with implementing the NPDES program in California and therefore entitled to deference under Department of Finance.

Finally, the Supreme Court in Department of Finance suggested that the inclusion of equivalent or substantially similar provisions by the U.S. EPA in other permits may support a finding that the provisions are necessary to achieve MEP. (Dept. of Finance, supra, 1 Cal.5th at p. 772.) The Los Angeles Water Board has examined the following U.S. EPA issued permits, among others, and concluded that they contain equivalent and/or substantially similar provisions: Massachusetts MS4 General Permit, Washington D.C. MS4 Permit, Albuquerque MS4 Watershed Permit, Boise/Garden City MS4 Permit, and Guam MS4 Permit. Previous sections of the Fact Sheet identify the specific provisions that are similar in these U.S. EPA issued permits.

2. Permittees have authority to fund the costs through service charges, fees, or assessments:

Even if any of the permit provisions could be considered unfunded state mandates, under Government Code section 17556, subdivision (d), a state mandate is not subject to reimbursement if the local agency has the authority to fund the costs through service charges, fees, or assessments. (Connell v. Superior Court (1997) 59 Cal.App.4th 382, 398.) Here, Permittees have the authority to levy service charges, fees, or assessments sufficient to pay for compliance with the Order.

Permittees certainly have fee authority under their police powers. (See, Cal. Const., art. XI, § 7; Freeman v. Contra Costa County Water Dist. (1971) 18 Cal.App.3d 404, 408 (“It cannot be denied that prevention of water pollution is a legitimate governmental objective, in furtherance of which the police power may be exercised.”); Department of Finance v. Commission on State Mandates (2021) 59 Cal.App.5th 546, 561-62 (holding in part that local governments have the authority sufficient to pay for inspection requirements for commercial and industrial facilities and construction sites to ensure compliance with various environmental regulations in an MS4 permit under their police powers for the prevention of water pollution).

This Fact Sheet demonstrates that numerous activities contribute to the pollutant loading from the MS4. Local agencies can levy service charges, fees, or assessments on these activities, independent of real property ownership. (See, e.g., Apartment Ass’n of Los Angeles County, Inc. v. City of Los Angeles (2001) 24 Cal.4th 830, 842 (upholding inspection fees associated with renting property).) The authority of a local agency to defray the cost of a program without raising taxes indicates that a program does not entail a cost subject to subvention. (Clovis Unified School Dist. v. Chiang (2010) 188 Cal.App.4th 794, 812 [“To the extent a local agency or school district ‘has the authority’ to charge for the mandated program or increased level of service, that charge cannot be recovered as a statemandated cost.”], quoting Connell v. Superior Court (1997) 59 Cal.App.4th 382, 401; County of Fresno v. State of California (1991) 53 Cal.3d 482, 487-488.) Permittees have argued in the past that their fee or taxation authority is constrained by article XIII D, section 6, of the California Constitution, also known as Proposition 218. (Cal. Const., art. XIII D, § 6, subd. (c); see also Howard Jarvis Taxpayers Association v. City of Salinas (2002) 98 Cal.App.4th 1351, 1358-1359.) However, Proposition 218 is not an impediment to Permittees’ fee authority.499 The Constitution has an exception to the voter approval requirements of Proposition 218, “for fees or charges for sewer, water, and refuse collection services.” (Cal.

Const. Article XIII D, section 6, subd. (c).) In recent years, the Legislature enacted two important pieces of legislation confirming fee authority without the need for voter approval. In Assembly Bill 2043 (2014), effective January 1, 2015, the Legislature amended the definition of “water” for purposes of articles XIII C and XIII D to mean “water from any source.” (Gov. Code, § 53750, subd. (n), amended by Assembly Bill 2043 (Stats. 2014, ch. 78, § 2.) In doing so, the Legislature stated that its act “is declaratory of existing law.” (Stats. 2014, ch. 78, § 1(c).) With Senate Bill 231 (2017), effective January 1, 2018, the Legislature “reaffirm[ed] and reiterate[d]” that the definition of “sewer” for purposes of article XIII D includes:
499 Such authority is also undiminished by Proposition 26, which specifically excludes assessments and property-related fees imposed in accordance with Proposition 218 from the definition of taxes. (Cal.

Const., art. XIII C, § 1, subd. (e)(7).).

systems, all real estate, fixtures, and personal property owned, controlled, operated, or managed in connection with or to facilitate sewage collection, treatment, or disposition for sanitary or drainage purposes, including lateral and connecting sewers, interceptors, trunk and outfall lines, sanitary sewage treatment or disposal plants or works, drains, conduits, outlets for surface or storm waters, and any and all other works, property, or structures necessary or convenient for the collection or disposal of sewage, industrial waste, or surface or storm waters.
(Gov. Code, § 53750, subd. (f), and § 53751, subd. (i), added by Senate Bill 231, Stats. 2017, ch. 536, § 2 (emphases added).) These legislative actions confirm that the Permittees have authority to raise fees or charges, without voter approval, for costs related to their MS4s.

In addition, Health and Safety Code section 5471, subdivision (a), gives dischargers fee authority for “services and facilities furnished…in connection with its water, sanitation, storm drainage, or sewerage system.” (Health & Safety Code, § 5471, subd. (a) (emphasis added).) Similarly, Public Resources Code section 40059, subdivision (a)(1), also confers fee authority on counties, cities, districts, or other local governmental agencies for “[a]spects of solid waste handling which are of local concern, including, but not limited to, frequency of collection, means of collection and transportation, level of services, charges and fees, and nature, location, and extent of providing solid waste handling services.” The ability of the Permittees to levy fees, assessments, or service charges to pay for compliance with the requirements of the Order cannot be disputed. In addition to the general authority above, some of the Permittees have specific authority to levy funds to pay for permit compliance. By way of example, the Ventura County Board of Supervisors approved the concept of a countywide NPDES permit program and the use of the Flood Management District (presently the Watershed Protection District) benefit assessment authority to finance it in April 1992. On June 30, 1992, the Ventura County Board of Supervisors adopted a benefit assessment fee for stormwater and flood management in the unincorporated areas of Ventura County and the cities within the County, to be used in part to finance the implementation of a countywide NPDES municipal stormwater permit program.

The Ventura County MS4 Permittees entered into agreement with the Watershed Protection District to finance the activities related to the Ventura County MS4 Permit for shared and district-wide expenses. The Permittees are also given the option to use the Benefit Assessment Program to finance their respective activities related to reducing the discharge of pollutants from their MS4s under the MS4 Permit. Therefore, the Ventura County Watershed Protection District (VCWPD), through the Benefit Assessment Program, has the authority to impose a fee or charge for implementation of this permit. Furthermore, in 2005, the Legislature authorized the VCWPD to increase property related fees to fund storm drainage service and facilities within its jurisdiction.500 The VCWPD has statutory authorization to levy an ad valorem tax upon all taxable property, an assessment upon all taxable real property in the district, or a fee imposed pursuant to Article XIII D of the California Constitution, to pay the costs and expenses of the district.501 500 Ventura County Watershed Protection Act, California Water Code Appendix, Chapter 46, § 46-12. 501 Ibid.

ATTACHMENT F – FACT SHEET F-386
The LACFCD also has specific statutory authority to levy a tax, fee, or charge to comply with the requirements of the Order, including implementation of approved WMPs. The LACFCD is authorized:

To levy a tax, in compliance with the applicable provisions of Article XIII C of the California Constitution, or impose a fee or charge, in compliance with the applicable provisions of Article XIII D of the California Constitution, to pay the costs and expenses of carrying out projects and programs to increase stormwater capture and reduce stormwater and urban runoff pollution in the district in accordance with criteria established by the ordinance adopted pursuant to subsection 8c. Projects and programs funded by the revenues from the tax, fee, or charge may include projects providing multiple benefits that increase water supply, improve water quality, and, where appropriate, provide community enhancements such as the greening of schools, parks, and wetlands, and increased public access to rivers, lakes, and streams.502
Revenues derived from any tax, fee, or charge imposed would be subject to specific allocations. Forty percent of any revenues derived from any LACFCD tax, fee, or charge is to be allocated to cities within the boundaries of the district and to the County of Los Angeles for implementation, operation and maintenance, and administration of project and programs within their respective jurisdictions. Fifty percent shall also be allocated to pay for the implementation, operation and maintenance, and administration of watershed-based projects and programs, including WMPs.503
Finally, even if voter approval may be required prior to levying fees, that does not mean that a local agency lacks the authority to levy fees. In Paradise Irrigation Dist. v. Commission on State Mandates (2019) 33 Cal.App.5th 174, 182, the Court considered whether the majority protest procedure added by Proposition 218 deprived local agencies of authority to impose fees for water service. Article XIII D, section 6(a) requires a local agency to identify parcels subject to a new fee, calculate the fee amount, and provide notice to affected property owners. (Cal.

Const., art. XIII D, § 6, subd. (a)(1).) If a majority of the property owners submit written protests against the fee, the fee may not be imposed. (Id., subd. (a)(2).) The Court held that the “majority protest procedures are properly construed as a powersharing arrangement between the districts and their customers, rather than a deprivation of fee authority.” (33 Cal.App.5th at p. 182.) It explained that, when considering how voter powers affect the ability of local governments to impose fees, courts “presume local voters will give appropriate consideration and deference to state mandated requirements . . . .” (Id. at p. 194, citing BighornDesert View Water Agency v. Verjil (2006) 39 Cal.4th 205, 220.) “Although this power-sharing arrangement has the potential for conflict, we must presume that both sides will act reasonably and in good faith.” (Id., at p. 192.) Further, the fact that, “as a matter of practical reality, the majority protest procedure allows water customers to defeat the District’s authority to levy fees” was not dispositive; “the inquiry into fee authority constitutes an issue of law rather than a question of fact.” (Id. at p. 195, citing Connell, supra, 59 Cal.App.4th at p. 401.) “Fee authority is a matter governed by statute rather than by factual considerations of practicality;” it 502 Cal.

is not controlled by whether municipalities have tried and failed to levy fees. (Id.) If there is statutory authority to levy fees, then there is no right to subvention. (Id.) XV. PUBLIC PARTICIPATION
The Los Angeles Water Board has considered the issuance of WDRs that will serve as an NPDES permit for MS4 discharges within the Los Angeles Region. The Los Angeles Water Board staff has encouraged public participation in the permit development process. Over a period of three years from May 2018 to May 2021, the Los Angeles Water Board has held multiple listening sessions, workshops, and Board meeting agenda items focusing on issues pertinent to Permittees in both counties. Additionally, Board staff have met with Permittees and interested stakeholders upon request. The following information is provided pursuant to 40 CFR § 124.8(b)(6) and (7).

A. Permittee and Stakeholder Participation in Permit Issuance Process

1. Notification: Intent to Issue a Region-Wide Phase I MS4 Permit On September 5, 2017, the Los Angeles Water Board sent a letter to all Permittees in the Los Angeles Region to announce the Board’s intent to issue a region-wide Phase I MS4 Permit.

2. Working Proposal
On December 10, 2019, the Los Angeles Water Board released a staff Working Proposal to Permittees in the Los Angeles Region and key stakeholders for discussion purposes. This staff working proposal did not constitute either a “draft permit” or a “proposed permit” as defined in Title 40 Code of Federal Regulations (40 CFR) sections 122.2 or 124.6. The Working Proposal allowed Permittees and stakeholders to provide oral and written input that would facilitate future discussion at board meetings/workshops and aid Board staff in developing the tentative draft permit.

3. Board Meetings and Workshops
The Los Angeles Water Board on many occasions starting in May 2018 had an item on its Meeting agenda to solicit comments and feedback from the Board, Permittees, and stakeholders on the issuance of the Regional MS4 Permit. Board staff has also presented on specific topics during public workshops, some of which were held at a regularly scheduled Board Meeting or special Board meeting (Board Workshop). Most of the meeting and workshop dates are summarized as follows:
a. Board Workshop: May 10, 2018
Board staff presented their monitoring data analysis for the Los Angeles River, San Gabriel River, and Los Cerritos Channel/Alamitos Bay Watersheds and discussed solutions to improve data reporting in the Regional MS4 Permit. b. Board Meeting: June 14, 2018
The Los Angeles Water Board had an agenda item to facilitate continued discussion of the Regional MS4 Permit (“MS4 standing item”). The purpose of the “MS4 standing item” was to provide a forum for Board members to discuss, and for Permittees and stakeholders to provide comments on, any aspect of the Regional MS4 Permit. This noticed item provided Permittees and other stakeholders with the opportunity to communicate directly with the Board regarding their interests and concerns about the current permits or pending issuance of the Regional MS4 Permit. The MS4 standing item also provided

APPENDIX XIV – DISADVANTAGED BUSINESS ENTERPRISES REQUIREMENTS The City is receiving federal funds for the water main replacement portion of this project.

As such, the following Disadvantaged Business Enterprises Requirements shall be followed by the Contractor. In the language below, the City is the “Recipient”, and the Contractor is the “Prime Contractor”.

Six Good Faith Efforts
Recipients are required to make the following good faith efforts whenever procuring construction, equipment, services, and supplies under an EPA financial assistance agreement. A Native American recipient or prime contractor must follow the six good faith efforts only if doing so would not conflict with exiting Tribal or Federal law, including but not limited to the Indian Self-Determination and Education Assistance Act.

1. Ensure DBEs are made aware of contracting opportunities to the fullest extent practicable through outreach and recruitment activities. For Indian Tribal, State, and Local Government recipients, this will include placing DBEs on solicitation lists and soliciting them whenever they are potential sources.

2. Make information on forthcoming opportunities available to DBEs, arrange time frames for contracts, and establish delivery schedules, where the requirements permit, in a way that encourages and facilitates participation by DBEs in the competitive process. This includes, whenever possible, posting solicitations for bids or proposals for a minimum of 30 calendar days before the bid or proposal closing date.

3. Consider in the contracting process whether firms competing for large contracts could subcontract with DBEs. For Indian Tribal, State, and Local Government recipients, this will include dividing total requirements when economically feasible into smaller tasks or quantities to permit maximum participation by DBEs in the competitive process.

4. Encourage contracting with a consortium of DBEs when a contract is too large for one of these firms to handle individually.

5. Use the services and assistance of the SBA and the Minority Business Development Agency of the Department of Commerce.

6. If the prime contractor awards subcontracts, require the prime contractor to take the steps in items 1 through 5.

EXHIBIT A
Tuesday, October 07, 2025 Reg CC MTG, Page *779

1. Require the recipient’s prime contractor to pay its subcontractor for satisfactory performance no more than 30 days from the prime contractor’s receipt of payment from the recipient.

2. Require the recipient’s prime contractor to notify the recipient in writing prior to any termination of a DBE subcontractor for convenience by the prime contractor.

3. Require the recipient’s prime contractor to employ the six good faith efforts described in §33.301 in procurement of goods and services, mentioned below:

4. If a DBE subcontractor fails to complete work under the subcontract for any reason, the recipient must require the prime contractor to employ the six good faith efforts described in §33.301 if soliciting a replacement subcontractor.

5. Ensure that each procurement contract it awards contains the term and condition specified in the appendix concerning compliance with the requirements of this part.

6. Ensure that the term and condition in the appendix is included in each procurement contract awarded by an entity receiving an identified loan under a financial assistance agreement to capitalize a revolving loan fund.

7. The contractor shall not discriminate on the basis of race, color, national origin or sex in the performance of this contract. The contractor shall carry out applicable requirements of 40 CFR part 33 in the award and administration of contracts awarded under EPA financial assistance agreements.

Failure by the contractor to carry out these requirements is a material breach of this contract which may result in the termination of this contract or other legally available remedies.

APPENDIX XVI – EPA GUIDELINES
 During construction, measures should be implemented to reduce air pollutant emissions, including maintenance of construction equipment engines and adherence to California Vehicle Code requirements to cover hauling trucks to prevent spills in streets during hauling.
 California Health and Safety Code
Section 7050.5 of the California Health and Safety Code states that in the event of discovery or recognition of any human remains in any location other than a dedicated cemetery, there shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains until the County Coroner has determined if the remains are subject to the Coroner’s authority. If the human remains are of Native American origin, the Coroner must notify the NAHC within 24 hours of this identification.

Unanticipated Discovery of Archaeological Resources
If archaeological resources are unexpectedly encountered during ground-disturbing activities, work in the immediate area must halt and an archaeologist meeting the Secretary of the Interior’s Professional Qualifications Standards for archeology (National Park Service 1983) should be contacted immediately to evaluate the find. If the discovery proves to be eligible for the NHRP, additional work such as data recovery excavation and Native American consultation may be warranted. The lead federal agency shall be aƯorded the opportunity to review discoveries in accordance with 36 CFR 800.13 – Post-review Discoveries.

Unanticipated Discovery of Human Remains
If human remains are unexpectedly found, California Health and Safety Code Section 7050.5 states no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. In the event of an unanticipated discovery of human remains, the County Coroner must be notified immediately. If the human remains are determined to be of Native American origin, the Coroner will notify the NAHC, which will determine and notify an MLD.

The MLD has 48 hours from being granted site access to make recommendations for the disposition of the remains. If the MLD does not make recommendations within 48 hours, the landowner shall reinter the remains in an area of the property secure from subsequent disturbance.

(A) In addition to wage and fringe benefit rates that have been determined to be prevailing under the procedures set forth in 29 CFR Part 1, a wage determination may contain, pursuant to § 1.3(f), wage and fringe benefit rates for classifications of laborers and mechanics for which conformance requests are regularly submitted pursuant to paragraph (a)(1)(iii) of this section, provided that:
( 1) The work performed by the classification is not performed by a classification in the wage determination for which a prevailing wage rate has been determined; ( 2) The classification is used in the area by the construction industry; and ( 3) The wage rate for the classification bears a reasonable relationship to the prevailing wage rates contained in the wage determination.
(B) The Administrator will establish wage rates for such classifications in accordance with paragraph (a)(1)(iii)(A)( 3) of this section. Work performed in such a classification must be paid at no less than the wage and fringe benefit rate listed on the wage determination for such classification. (iii) Conformance
(A) The contracting officer must require that any class of laborers or mechanics, including helpers, which is not listed in the wage determination and which is to be employed under the contract be classified in conformance with the wage determination. Conformance of an additional classification and wage rate and fringe benefits is appropriate only when the following criteria have been met:
( 1) The work to be performed by the classification requested is not performed by a classification in the wage determination; and
( 2) The classification is used in the area by the construction industry; and ( 3) The proposed wage rate, including any bona fide fringe benefits, bears a reasonable relationship to the wage rates contained in the wage determination.
(B) The conformance process may not be used to split, subdivide, or otherwise avoid application of classifications listed in the wage determination.
(C) If the contractor and the laborers and mechanics to be employed in the classification (if known), or their representatives, and the contracting officer agree on the classification and wage rate (including the amount designated for fringe benefits where appropriate), a report of the action taken will be sent by the contracting officer by email to [email protected]. The Administrator, or an authorized representative, will approve, modify, or disapprove every additional classification action within 30 days ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *795
of receipt and so advise the contracting officer or will notify the contracting officer within the 30–day period that additional time is necessary.
(D) In the event the contractor, the laborers or mechanics to be employed in the classification or their representatives, and the contracting officer do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), the contracting officer will, by email to [email protected], refer the questions, including the views of all interested parties and the recommendation of the contracting officer, to the Administrator for determination. The Administrator, or an authorized representative, will issue a determination within 30 days of receipt and so advise the contracting officer or will notify the contracting officer within the 30–day period that additional time is necessary.
(E) The contracting officer must promptly notify the contractor of the action taken by the Wage and Hour Division under paragraphs (a)(1)(iii)(C) and (D) of this section. The contractor must furnish a written copy of such determination to each affected worker, or it must be posted as a part of the wage determination. The wage rate (including fringe benefits where appropriate) determined pursuant to paragraph (a)(1)(iii)(C) or (D) of this section must be paid to all workers performing work in the classification under this contract from the first day on which work is performed in the classification. (iv) Fringe benefits not expressed as an hourly rate
Whenever the minimum wage rate prescribed in the contract for a class of laborers or mechanics includes a fringe benefit which is not expressed as an hourly rate, the contractor may either pay the benefit as stated in the wage determination or may pay another bona fide fringe benefit or an hourly cash equivalent thereof.
(v) Unfunded plans
If the contractor does not make payments to a trustee or other third person, the contractor may consider as part of the wages of any laborer or mechanic the amount of any costs reasonably anticipated in providing bona fide fringe benefits under a plan or program, Provided, That the Secretary of Labor has found, upon the written request of the contractor, in accordance with the criteria set forth in § 5.28, that the applicable standards of the Davis-Bacon Act have been met. The Secretary of Labor may require the contractor to set aside in a separate account assets for the meeting of obligations under the plan or program.
(vi) Interest
In the event of a failure to pay all or part of the wages required by the contract, the contractor will be required to pay interest on any underpayment of wages.
(2) Withholding
(i) Withholding requirements
The EPA, grant recipient, subrecipient at any tier, and/or contracting agency may, upon its own action, or must, upon written request of an authorized representative of the Department of Labor, withhold or cause to be withheld from the contractor so much of the accrued payments or advances as may be ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *796
considered necessary to satisfy the liabilities of the prime contractor or any subcontractor for the full amount of wages and monetary relief, including interest, required by the clauses set forth in paragraph (a) of this section for violations of this contract, or to satisfy any such liabilities required by any other Federal contract, or federally assisted contract subject to Davis-Bacon labor standards, that is held by the same prime contractor (as defined in § 5.2).

The necessary funds may be withheld from the contractor under this contract, any other Federal contract with the same prime contractor, or any other federally assisted contract that is subject to Davis-Bacon labor standards requirements and is held by the same prime contractor, regardless of whether the other contract was awarded or assisted by the same agency, and such funds may be used to satisfy the contractor liability for which the funds were withheld.

In the event of a contractor's failure to pay any laborer or mechanic, including any apprentice or helper working on the site of the work (or otherwise working in construction or development of the project under a development statute) all or part of the wages required by the contract, or upon the contractor's failure to submit the required records as discussed in paragraph (a)(3)(iv) of this section, the EPA, grant recipient, subrecipient at any tier, and/or contracting agency may on its own initiative and after written notice to the contractor, sponsor, applicant, owner, or other entity, as the case may be, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds until such violations have ceased.
(ii) Priority to withheld funds
The Department has priority to funds withheld or to be withheld in accordance with paragraph (a)(2)(i) or (b)(3)(i) of this section, or both, over claims to those funds by:
(A) A contractor's surety(ies), including without limitation performance bond sureties and payment bond sureties;
(B) A contracting agency for its reprocurement costs;
(C) A trustee(s) (either a court-appointed trustee or a U.S. trustee, or both) in bankruptcy of a contractor, or a contractor's bankruptcy estate;
(D) A contractor's assignee(s);
(E) A contractor's successor(s); or
(F) A claim asserted under the Prompt Payment Act, 31 U.S.C. 3901–3907. (3) Records and certified payrolls
(i) Basic record requirements
(A) Length of record retention
All regular payrolls and other basic records must be maintained by the contractor and any subcontractor during the course of the work and preserved for all laborers and mechanics working at the site of the ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *797
work (or otherwise working in construction or development of the project under a development statute) for a period of at least 3 years after all the work on the prime contract is completed. (B) Information required
Such records must contain the name; Social Security number; last known address, telephone number, and email address of each such worker; each worker's correct classification(s) of work actually performed; hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in 40 U.S.C. 3141(2)(B) of the DavisBacon Act); daily and weekly number of hours actually worked in total and on each covered contract; deductions made; and actual wages paid.
(C) Additional records relating to fringe benefits
Whenever the Secretary of Labor has found under paragraph (a)(1)(v) of this section that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in 40 U.S.C. 3141(2)(B) of the Davis-Bacon Act, the contractor must maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, and that the plan or program has been communicated in writing to the laborers or mechanics affected, and records which show the costs anticipated or the actual cost incurred in providing such benefits.
(D) Additional records relating to apprenticeship. Contractors with apprentices working under approved programs must maintain written evidence of the registration of apprenticeship programs, the registration of the apprentices, and the ratios and wage rates prescribed in the applicable programs. (ii) Certified payroll requirements
(A) Frequency and method of submission
The contractor or subcontractor must submit weekly, for each week in which any DBA- or Related Actscovered work is performed, certified payrolls to the contracting agency if the agency is a party to the contract, but if the agency is not such a party, the contractor will submit the certified payrolls to the applicant, sponsor, owner, or other entity, as the case may be, that maintains such records, for transmission to the contracting agency. The prime contractor is responsible for the submission of all certified payrolls by all subcontractors. A contracting agency or prime contractor may permit or require contractors to submit certified payrolls through an electronic system, as long as the electronic system requires a legally valid electronic signature; the system allows the contractor, the contracting agency, and the Department of Labor to access the certified payrolls upon request for at least 3 years after the work on the prime contract has been completed; and the contracting agency or prime contractor permits other methods of submission in situations where the contractor is unable or limited in its ability to use or access the electronic system.
(B) Information required
The certified payrolls submitted must set out accurately and completely all of the information required to be maintained under paragraph (a)(3)(i)(B) of this section, except that full Social Security numbers and last known addresses, telephone numbers, and email addresses must not be included on weekly transmittals. Instead, the certified payrolls need only include an individually identifying number for each ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *798
worker ( e.g., the last four digits of the worker's Social Security number). The required weekly certified payroll information may be submitted using Optional Form WH–347 or in any other format desired.

Optional Form WH–347 is available for this purpose from the Wage and Hour Division website at https://www.dol.gov/sites/dolgov/files/WHD/legacy/files/wh347/.pdf or its successor website. It is not a violation of this section for a prime contractor to require a subcontractor to provide full Social Security numbers and last known addresses, telephone numbers, and email addresses to the prime contractor for its own records, without weekly submission by the subcontractor to the sponsoring government agency (or the applicant, sponsor, owner, or other entity, as the case may be, that maintains such records).
(C) Statement of Compliance
Each certified payroll submitted must be accompanied by a “Statement of Compliance,” signed by the contractor or subcontractor, or the contractor's or subcontractor's agent who pays or supervises the payment of the persons working on the contract, and must certify the following:
( 1) That the certified payroll for the payroll period contains the information required to be provided under paragraph (a)(3)(ii) of this section, the appropriate information and basic records are being maintained under paragraph (a)(3)(i) of this section, and such information and records are correct and complete;
( 2) That each laborer or mechanic (including each helper and apprentice) working on the contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or indirectly from the full wages earned, other than permissible deductions as set forth in 29 CFR part 3; and ( 3) That each laborer or mechanic has been paid not less than the applicable wage rates and fringe benefits or cash equivalents for the classification(s) of work actually performed, as specified in the applicable wage determination incorporated into the contract. (D) Use of Optional Form WH–347
The weekly submission of a properly executed certification set forth on the reverse side of Optional Form WH–347 will satisfy the requirement for submission of the “Statement of Compliance” required by paragraph (a)(3)(ii)(C) of this section.
(E) Signature
The signature by the contractor, subcontractor, or the contractor's or subcontractor's agent must be an original handwritten signature or a legally valid electronic signature. (F) Falsification
The falsification of any of the above certifications may subject the contractor or subcontractor to civil or criminal prosecution under 18 U.S.C. 1001 and 31 U.S.C. 3729. (G) Length of certified payroll retention
The contractor or subcontractor must preserve all certified payrolls during the course of the work and for a period of 3 years after all the work on the prime contract is completed.

ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *799
(iii) Contracts, subcontracts, and related documents
The contractor or subcontractor must maintain this contract or subcontract and related documents including, without limitation, bids, proposals, amendments, modifications, and extensions. The contractor or subcontractor must preserve these contracts, subcontracts, and related documents during the course of the work and for a period of 3 years after all the work on the prime contract is completed. (iv) Required disclosures and access
(A) Required record disclosures and access to workers
The contractor or subcontractor must make the records required under paragraphs (a)(3)(i) through (iii) of this section, and any other documents that the EPA, recipient, or subrecipient at any tier, and/or contracting agency, or the Department of Labor deems necessary to determine compliance with the labor standards provisions of any of the applicable statutes referenced by § 5.1, available for inspection, copying, or transcription by authorized representatives of the EPA, recipient, or subrecipient at any tier, and/or contracting agency, or the Department of Labor, and must permit such representatives to interview workers during working hours on the job.
(B) Sanctions for non-compliance with records and worker access requirements If the contractor or subcontractor fails to submit the required records or to make them available, or refuses to permit worker interviews during working hours on the job, the Federal agency may, after written notice to the contractor, sponsor, applicant, owner, or other entity, as the case may be, that maintains such records or that employs such workers, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available, or to permit worker interviews during working hours on the job, may be grounds for debarment action pursuant to § 5.12. In addition, any contractor or other person that fails to submit the required records or make those records available to WHD within the time WHD requests that the records be produced will be precluded from introducing as evidence in an administrative proceeding under 29 CFR part 6 any of the required records that were not provided or made available to WHD. WHD will take into consideration a reasonable request from the contractor or person for an extension of the time for submission of records. WHD will determine the reasonableness of the request and may consider, among other things, the location of the records and the volume of production.
(C) Required information disclosures
Contractors and subcontractors must maintain the full Social Security number and last known address, telephone number, and email address of each covered worker, and must provide them upon request to the Environmental Protection Agency if the agency is a party to the contract, or to the Wage and Hour Division of the Department of Labor. If the Federal agency is not such a party to the contract, the contractor, subcontractor, or both, must, upon request, provide the full Social Security number and last known address, telephone number, and email address of each covered worker to the applicant, sponsor, owner, or other entity, as the case may be, that maintains such records, for transmission to the EPA, recipient, or subrecipient at any tier, contracting agency, the contractor, or the Wage and Hour Division of the Department of Labor for purposes of an investigation or other compliance action.

(4) Apprentices and Equal Employment Opportunity
(i) Apprentices
(A) Rate of pay
Apprentices will be permitted to work at less than the predetermined rate for the work they perform when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the U.S. Department of Labor, Employment and Training Administration, Office of Apprenticeship (OA), or with a State Apprenticeship Agency recognized by the OA. A person who is not individually registered in the program, but who has been certified by the OA or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice, will be permitted to work at less than the predetermined rate for the work they perform in the first 90 days of probationary employment as an apprentice in such a program. In the event the OA or a State Apprenticeship Agency recognized by the OA withdraws approval of an apprenticeship program, the contractor will no longer be permitted to use apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved. (B) Fringe benefits
Apprentices must be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringe benefits must be paid in accordance with that determination. (C) Apprenticeship ratio
The allowable ratio of apprentices to journey workers on the job site in any craft classification must not be greater than the ratio permitted to the contractor as to the entire work force under the registered program or the ratio applicable to the locality of the project pursuant to paragraph (a)(4)(i)(D) of this section. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated in paragraph (a)(4)(i)(A) of this section, must be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under this section must be paid not less than the applicable wage rate on the wage determination for the work actually performed. (D) Reciprocity of ratios and wage rates
Where a contractor is performing construction on a project in a locality other than the locality in which its program is registered, the ratios and wage rates (expressed in percentages of the journey worker’s hourly rate) applicable within the locality in which the construction is being performed must be observed. If there is no applicable ratio or wage rate for the locality of the project, the ratio and wage rate specified in the contractor's registered program must be observed. (ii) Equal employment opportunity
ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *801
The use of apprentices and journey workers under this part must be in conformity with the equal employment opportunity requirements of Executive Order 11246, as amended, and 29 CFR part 30. (5) is reserved
(6) Subcontracts
The contractor or subcontractor must insert in any subcontracts the clauses contained in paragraphs (a)(1) through (11) of this section or a link to the DBRA Requirements for Contractors and Subcontractors Under EPA Grants document on EPA’s Contract Provisions for Davis-Bacon and Related Acts webpage, along with the applicable wage determination(s) and such other clauses or contract modifications as the Environmental Protection Agency may by appropriate instructions require, and a clause requiring the subcontractors to include these clauses and wage determination(s) in any lower tier subcontracts. The prime contractor is responsible for the compliance by any subcontractor or lower tier subcontractor with all the contract clauses in this section. In the event of any violations of these clauses, the prime contractor and any subcontractor(s) responsible will be liable for any unpaid wages and monetary relief, including interest from the date of the underpayment or loss, due to any workers of lower-tier subcontractors, and may be subject to debarment, as appropriate. (7) – (9) are reserved
(10) Certification of Eligibility
(i) By entering into this contract, the contractor certifies that neither it nor any person or firm who has an interest in the contractor's firm is a person or firm ineligible to be awarded Government contracts by virtue of 40 U.S.C. 3144(b) or § 5.12(a).
(ii) No part of this contract shall be subcontracted to any person or firm ineligible for award of a Government contract by virtue of 40 U.S.C. 3144(b) or § 5.12(a). (iii) The penalty for making false statements is prescribed in the U.S. Code, Title 18 Crimes and Criminal Procedure, 18 U.S.C. 1001.
(11) Anti-Retaliation
It is unlawful for any person to discharge, demote, intimidate, threaten, restrain, coerce, blacklist, harass, or in any other manner discriminate against, or to cause any person to discharge, demote, intimidate, threaten, restrain, coerce, blacklist, harass, or in any other manner discriminate against, any worker or job applicant for:
(i) Notifying any contractor of any conduct which the worker reasonably believes constitutes a violation of the DBA, Related Acts, this part, or 29 CFR part 1 or 3; (ii) Filing any complaint, initiating or causing to be initiated any proceeding, or otherwise asserting or seeking to assert on behalf of themselves or others any right or protection under the DBA, Related Acts, this part, or 29 CFR part 1 or 3;
(iii) Cooperating in any investigation or other compliance action, or testifying in any proceeding under the DBA, Related Acts, this part, or 29 CFR part 1 or 3; or ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *802
(iv) Informing any other person about their rights under the DBA, Related Acts, this part, or 29 CFR part 1 or 3.

================================================================ Note: Executive Order (EO) 13706, Establishing Paid Sick Leave for Federal Contractors applies to all contracts subject to the Davis-Bacon Act for which the contract is awarded (and any solicitation was issued) on or after January 1, 2017. If this contract is covered by the EO, the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year.

Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care; to assist a family member (or person who is like family to the employee) who is ill, injured, or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member (or person who is like family to the employee) who is a victim of, domestic violence, sexual assault, or stalking.

https://www.dol.gov/agencies/whd/government-contracts.

Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (iii)).
---------------------------------------------------------------- The body of each wage determination lists the classifications and wage rates that have been found to be prevailing for the type(s) of construction and geographic area covered by the wage determination. The classifications are listed in alphabetical order under rate identifiers indicating whether the particular rate is a union rate (current union negotiated rate), a survey rate, a weighted union average rate, a state adopted rate, or a supplemental classification rate.

Union Rate Identifiers
A four-letter identifier beginning with characters other than ""SU"", ""UAVG"", ?SA?, or ?SC? denotes that a union rate was prevailing for that classification in the survey. Example:

PLUM0198-005 07/01/2024. PLUM is an identifier of the union whose collectively bargained rate prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. The date, 07/01/2024 in the example, is the effective date of the most current negotiated rate.

Union prevailing wage rates are updated to reflect all changes over time that are reported to WHD in the rates
in the collective bargaining agreement (CBA) governing the classification.

Union Average Rate Identifiers
The UAVG identifier indicates that no single rate prevailed for those classifications, but that 100% of the data reported for the classifications reflected union rates. EXAMPLE:

UAVG-OH-0010 01/01/2024. UAVG indicates that the rate is a weighted union average rate. OH indicates the State of Ohio.

The next number, 0010 in the example, is an internal number used in producing the wage determination. The date, 01/01/2024 in the example, indicates the date the wage determination was ATTACHMENT 3
Tuesday, October 07, 2025 Reg CC MTG, Page *833
updated to reflect the most current union average rate.

A UAVG rate will be updated once a year, usually in January, to reflect a weighted average of the current rates in the
collective bargaining agreements on which the rate is based.

Survey Rate Identifiers
The ""SU"" identifier indicates that either a single non-union rate prevailed (as defined in 29 CFR 1.2) for this
classification in the survey or that the rate was derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As a weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SUFL2022-007 6/27/2024. SU indicates the rate is a single non-union
prevailing rate or a weighted average of survey data for that classification. FL indicates the State of Florida. 2022 is the year of the survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. The date, 6/27/2024 in the example, indicates the survey completion date for the classifications and rates under that identifier. ?SU? wage rates typically remain in effect until a new survey is conducted. However, the Wage and Hour Division (WHD) has the discretion to update such rates under 29 CFR 1.6(c)(1).

State Adopted Rate Identifiers
The ""SA"" identifier indicates that the classifications and prevailing wage rates set by a state (or local) government were adopted under 29 C.F.R 1.3(g)-(h). Example: SAME2023-007 01/03/2024. SA reflects that the rates are state adopted. ME refers to the State of Maine. 2023 is the year during which the state completed the survey on which the listed classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination.

The date, 01/03/2024 in the example, reflects the date on which the classifications and rates under the ?SA? identifier took effect under state law in the state from which the rates were adopted.

1 TO: City Council
FROM: Andrew Vialpando, City Manager
PREPARED BY: Andres Gonzalez, Public Works Director
MEETING DATE: October 7, 2025
SUBJECT: Professional Services Agreement with TDG Engineering, Inc. for Civil Engineering Design Services for the Local Travel Network Project

RECOMMENDED ACTION
Approve a Professional Services Agreement with TDG Engineering, Inc. for professional civil engineering design services for the City of Lomita’s Local Travel Network Project in the amount of $596,398, plus a 15% contingency amount of $89,460, for a total not to exceed amount of $685,858; and authorize the City Manager to execute the agreement.

BACKGROUND
Over the past 15 years, research conducted by the South Bay Cities Council of Governments (SBCCOG) demonstrated that approximately 70% of trips in the South Bay occur within 3 miles of an individual’s home, and 90% are within 10 miles. The data showed that these trips are too short for the frequency and quality of the transit service in the South Bay, but too far to walk. By replacing the trips that are currently being made with internal combustion engine powered cars with zero-emission micro-mobility vehicles, greenhouse gas emissions would be reduced.

To encourage right-sizing of vehicles for short trips and to establish safe routes for micromobility vehicles, the SBCCOG has championed the development of a Local Travel Network (LTN) for getting around in the South Bay. The proposed 243-mile LTN is a system of slow-speed streets to be shared by all forms of mobility including small, lowspeed vehicles (i.e., street-legal golf carts, e-bikes, pedal bikes, e-scooters, etc.), safely connecting neighborhoods with popular destinations. In addition, the LTN can help in reducing vehicular congestion while providing a network for alternative and active transportation.

CITY OF LOMITA

CITY COUNCIL REPORT
Item No. SCH 8a
Tuesday, October 07, 2025 Reg CC MTG, Page *880
2 In Lomita, approximately 5.35 miles of network are proposed, primarily along Eshelman Avenue, Pennsylvania Avenue, 250th Street and 255th Street. Traffic calming measures along Eshelman Avenue at the intersections of Walnut Street, Ebony Lane, and 253rd Street are required in the network plans. Many of these traffic calming measures were identified in other studies, including the City’s 2023 Traffic Calming Toolkit, to enhance safety even if the LTN were not being implemented. Maps showing the proposed LTN routes and details of the proposed traffic calming features included in this project are shown in Attachment 1.

On March 19, 2024, City Council authorized the SBCCOG to submit an application for regional funding to the Measure M Transportation System and Mobility Improvements Program for the South Bay Local Travel Network and Related Safety Enhancements in Lomita project. This application requested funding for the establishment of approximately

5.35 miles of LTN routes within the City of Lomita.

In September 2024, the Los Angeles County Metropolitan Transportation Authority (Metro) approved the city’s funding application allocating $6,651,895 for the design and construction of improvements within Lomita for the Local Travel Network and related traffic calming measures.

On April 15, 2025, City Council adopted Resolution No. 2025-08 that authorized the City Manager to execute the contract with Metro for the Measure M Transportation System and Mobility Improvements Program funding for the South Bay Local Travel Network & Related Safety Enhancements in Lomita project. The contract, Funding Agreement MM4601.18, was fully executed on April 21, 2025.

DISCUSSION
The Request for Proposals (RFP) for Professional Civil Engineering Design Services for the City of Lomita’s Local Travel Network was issued on July 25, 2025. The RFP was emailed to six of the seven pre-qualified design firms established by the SBCCOG; the seventh firm did not offer all the disciplines needed for this project.

The firms were pre-qualified through the SBCCOG Local Travel Network Project Management and Technical Services consultant bench selection process. An evaluation committee of City staff, SBCCOG, and staff from other SBCCOG-member cities reviewed all proposals for staff qualifications, recent relevant project experience, and proposed scopes of work. The committee interviewed both firms and ranked the consulting firms based on which firm could best provide the requested services. TDG Engineering, Inc. (Toole Design Group) was the highest ranked firm.

Toole Design Group received the highest ranking overall based on the above-mentioned criteria. Toole Design Group is a planning and design consulting firm focused on supporting innovative streets and dynamic communities where people of all ages and abilities can enjoy walking, biking, and access to transit. The firm has extensive experience with complete streets projects throughout California and across the nation.

Tuesday, October 07, 2025 Reg CC MTG, Page *881
3 Locally, they are familiar with the City of Lomita and local traffic concerns as they are the City’s consultant for the Citywide School Loading Zone Study. Additionally, they are working with the SBCCOG on a related Local Travel Network project.

Toole Design Group will use Psomas as a subconsultant on this project for surveying, civil engineering design, and environmental services. Psomas is a full-service consulting firm, providing engineering, environmental, and surveying services. Founded in 1946, Psomas has 16 offices in California, Arizona, Washington, and Utah. Psomas is familiar with the City of Lomita and has worked with the City on a range of projects. Additionally, they have partnered with Toole Design Group on previous projects.

Staff recommends awarding a Professional Services Agreement (Attachment 3) to TDG Engineering, Inc. aka Toole Design Group to provide civil engineering design services for the City of Lomita’s Local Travel Network project. Based on Toole Design Group’s proposal and the project scope, staff negotiated a final fee of $596,398. Staff also recommends approval of a 15% contingency in the amount of $89,460, which will be included in the agreement. This results in a not to exceed project budget of $685,858.

The design of the project is scheduled to start in October 2025, pending Council approval, and is expected to be completed in 8 months.

FISCAL IMPACT
The total contract amount for Professional Civil Engineering Design Services for the Local Travel Network Project will not exceed $658,858. These services are fully funded through Metro’s Measure M Transportation System and Mobility Improvements Grant Program.

To cover the design costs for the project, an appropriation of $685,858 from the City’s restricted funds is required. This fund will be reimbursed through the grant awarded to the City by Metro under the Measure M Transportation System and Mobility Improvements Program.

VISION, MISSION, VALUES, AND STRATEGIC OUTCOMES
The City’s Vision, Mission, and Values set the standard for the organization, establish priorities, uniformity and guidelines; and provide the framework for policy decision making. The Strategic Outcomes were implemented to provide a pathway to achieving the City’s Vision. This item aligns with Strategic Outcome No. 5: City Infrastructure & Water Utility – Investing in reliable, sustainable infrastructure.

OPTIONS

1. Approve recommended action.

TO: SBCCOG Board of Directors
FROM: SBCCOG Transportation Committee
SUBJECT: Local Travel Network Project Management and Technical Services Request for Qualifications – Consultant Bench Selection

BACKGROUND
Since 2021, the SBCCOG has partnered with its member jurisdictions to implement the South Bay Local Travel Network (LTN). The LTN is SBCCOG’s context specific approach to providing a safe, connected, and low stress street network that encourages the use of slow-speed, zero-emission micromobility modes for local trips. To date, the City of El Segundo has implemented an LTN pilot program (November 2023) and is preparing for full implementation of the network. Subsequently, Redondo Beach, Carson, Lomita, and Lawndale are in various stages of implementing the LTN. Over the next few years, other SBCCOG member jurisdictions are anticipated to join the network providing slow-speed infrastructure both within and between their communities.

As an increasing number of member jurisdictions implement the LTN, city staff have expressed challenges in capacity and have looked to the SBCCOG to provide support. To address this demand, the SBCCOG, in consultation with a subcommittee of city public works professionals, solicited a bench of consultants to provide project management and technical assistance to member jurisdictions for engineering, planning and design work to support the implementation of the LTN, including preparation of design solutions to implement core LTN elements as well as ancillary street calming and roadway improvements, developing Measure M LTN project proposals, PS&E design, and delivering final projects. Proposers were asked to provide qualifications across seven (7) disciplines:

1. Planning and Engineering Design to Support Micromobility

2. LTN Enhancement with Bicycle Infrastructure

3. Transportation Planning and Engineering Studies to Support Micromobility Infrastructure on Major Arterials or Streets Above 35 MPH

4. Experimental Roadway Treatments

5. Evaluation of Network

6. Engagement and Outreach Materials

7. Measure M Application and Grant Development
Attachment 2
Tuesday, October 07, 2025 Reg CC MTG, Page *886
Proposers were invited to submit qualifications for specific disciplines that aligned with their experience and expertise. This process was designed to prequalify proposers for the disciplines in which they chose to participate.

SBCCOG member jurisdictions will have the opportunity to enter into contract agreements with consultants on the prequalified list, saving the cities time and money in the selection process for the specific work that they need among the seven disciplines. Based on SBCCOG member jurisdictions’ needs, jurisdictions may also issue an RFP to the prequalified list of consultants (task order or bench solicitation) or opt for a public solicitation.

ANALYSIS
Seven (7) proposals were received and reviewed by the proposal review committee. The SBCCOG received proposal submissions for varying disciplines from Fehr and Peers, GHD, GTS, HW Lochner (formerly KOA), Iteris, MNS, and Toole Design (Table 2).

The SBCCOG review process followed standard RFQ selection protocol and schedule:
• A proposal review committee was formed:
• SBCCOG staff: Jacki Bacharach, Executive Director; Shannon Heffernan, Contract Planner; Aaron Baum, Senior Project Manager; Anne Tsai, Project Coordinator
• City staff: Jennifer Howell, Lomita; Ryan Liu, Redondo Beach; Elias Sassoon, El Segundo; Erik Zandvliet, Manhattan Beach
• June 23
th – July 2nd: Review committee members were asked to review and score the proposals according to the team’s qualifications including related experience with similar projects and projects within the study area, understanding of project goals, and key staff expertise.
• July 8
th: The review committee met via Zoom to review scoring and pre-qualify firms for the consultant bench.

Following deliberation by the review committee, the Fehr & Peers team emerged as the topranking firm (Table 1). Fehr & Peers demonstrated the strongest familiarity with the Local Travel Network and technical expertise to support city implementation of the LTN. The review committee discussed the advantages of employing a single consulting firm across multiple city LTN projects to synergize planning and design processes as well as to coordinate inter-city connections. However, the committee also acknowledged the need to maintain flexibility for cities to select the most suitable firms for their individual needs.

With this in mind, and to maintain flexibility for cities, the review committee recommends prequalifying all seven proposers for the consultant bench but recommends the top firm Fehr & Peers be recognized as such. Cities may choose to enter into contract agreements with the topranking consultant or utilize the review committee rankings (Table 1) to inform the selection of a consultant for their project needs. The SBCCOG and members of the review committee also highly encourage adjacent cities to consider using the same contractor and to consider collaboratively entering joint contracts.
