Pacific Grove
For the 2024-2025 permit year, four sites were monitored: 8th Street, Greenwood Park, Lover’s Point and Pico. The two sites on the Hopkins Marine StaƟon campus that were historically monitored were not sampled. The 8th Street, Greenwood Park and Lover’s Point watersheds have dry weather urban runoff diversions within the storm drain system that divert flow to Monterey One Water for treatment from April to October. In recent years, this dry-weather diversion has been leŌ on throughout the winter season which eliminates storm drain runoff into the ocean within the diversion area. For the 2024 Dry Run and First Flush the diversion remained in operaƟon. Dry Run and First Flush samples were collected at the following sites:

Greenwood Park (upstream of the diversion), Pico (outside of the diversion area), Lover’s Point (upstream of the diversion) and 8th Street (downstream of the diversion). Hopkins in Pacific Grove had no flow for the Dry Run and was not sampled during First Flush.

44 Conclusion
Since 2006, the MRSWMP Monterey SEA program has uƟlized MBNMS’ Dry Run and First Flush protocols to ascertain what concentraƟons of pollutants are found in both dry and wet weather storm drain flows that discharge into surface waters or the ocean. The ouƞall sites monitored as part of the MRSWMP program were selected as sites representaƟve of water quality throughout a jurisdicƟon. For the 2024-2025 permit year, fourteen ouƞall sites were monitored for Dry Run and First Flush in six jurisdicƟons: Monterey County, Seaside-Sand City, Monterey, Pacific Grove, and Carmel-by-the-Sea.

Ouƞall monitoring results provide city representaƟves and residents with informaƟon on the concentraƟon of pollutants from their own streets and neighborhoods. CiƟes can use this informaƟon not only to saƟsfy permit requirements but also engage and inform residents on pracƟcal soluƟons for prevenƟng water quality polluƟon in storm drains. While First Flush results due to higher loads typically indicate worst-case scenarios of water quality, results can provide insight into sub-watersheds within each jurisdicƟon that warrant further aƩenƟon and invesƟgaƟon into pollutant sources. Source tracking within sub-watersheds is an important and useful tool for local jurisdicƟons. Using these results can help pinpoint problem watersheds to track down sources of pollutants before they reach receiving waters and Monterey Bay NaƟonal Marine Sanctuary. Sub-watersheds with elevated orthophosphate, E. coli, Enterococcus, and surfactants are high on the list for watersheds needing further invesƟgaƟon into sources and possible miƟgaƟon through public educaƟon campaigns.

2 Executive Summary
This report describes the results of monitoring performed from 3/1/2018 to 3/28/2022 to trace potential sources of fecal indicator bacteria (FIB) and copper exceedances in ocean receiving water adjacent to the 4th Avenue storm drain that discharges from the City of Carmel-by-the-Sea (Carmel) into Carmel Bay.

Since the program’s beginning, samples have been collected from six watershed sites (WS), three building rain downspouts, the large storm drain (SD) at the end of 4th Avenue, a nearshore receiving water site (RW) directly off the SD, and an ocean water site (OW) north of the receiving water site. Nine storms have been sampled. Not all sites were sampled in each storm, as results from previous samples guided program changes to focus on existing sites or add new sites to delineate areas requiring management actions. WS2 was consistently sampled at its discharge into SD. Subwatershed WS1 was not sampled after 3/20/2019 and subwatersheds WS3, WS3a, and WS3b were not sampled before 3/16/2020.

Measurements included concentrations of Enterococcus (upon which water quality benchmarks are based) and dog, gull, human, and anthropogenic (dog + human) fecal bacteria, and dissolved and total copper. The contributions of WS2 and its subwatersheds to SD discharges were estimated by converting concentration data into load estimates (concentration x watershed acreage).

Watershed Loads and Sources
Contributions of loads from WS2 to SD differed among fecal indicators. On average, WS2 contributed 46% of Enterococcus loads from SD, indicating broadly distributed sources across the entire SD watershed. Loads of dog, gull, human, and anthropogenic fecal bacteria from WS2 averaged 4 – 51,000 times greater that loads from SD, indicating potent sources for these fecal bacteria within WS2. WS1 loads of dog fecal bacteria averaged 72% of WS2 loads and none of the other fecal bacteria loads from WS1 exceeded 27% of WS2 loads, suggesting that WS1 could be an important source of dog fecal bacteria. Loads of Enterococcus, gull, and human fecal bacteria from subwatershed WS3 to WS2 averaged 84%, 13%, and 48%, respectively of WS2 loads. Loads of dog and anthropogenic fecal indicators from WS3 were 5.1 and 2.4 times greater than from WS2, identifying WS3 as the major contributor of these indicators into WS2 and SD. Loads of dog and human fecal bacteria from WS3a averaged 2 – 24 times greater that those from WS3. Dog and gull fecal bacteria were not measured in WS3b, but loads of human fecal bacteria from this subwatershed averaged 45 times greater than from WS3. These results identify WS3a and WS3b as important subwatersheds for management actions to reduce loads of dog, human, and anthropogenic fecal bacteria into SD.

Following high concentrations of human fecal bacteria in WS2 on 3/13/18, the sewer line under Junipero Street between 1st Avenue and 2nd Avenue was relined in mid 2020.

Concentrations of human fecal bacteria before (T1) and after (T2) the sewer was relined were not statistically different, probably due to small numbers of samples, but concentrations in T2 remained several orders of magnitude below the value seen on 3/13/18. Robust ATTACHMENT 3

3 concentrations of human fecal bacteria in WS3, WS3a, and WS3b suggest continuing sources of human fecal bacteria in those subwatersheds.

Copper loads from WS2 averaged 50% of those from SD, indicating broadly distributed sources within the entire SD watershed. Copper loads from WS3 averaged <40% of WS2 loads, which is also consistent with broadly distributed sources. Copper concentrations in watershed and SD samples were dominated by dissolved copper, indicating that the use of treatment devices that focus on sediment removal would not be very effective at reducing copper loads to the receiving water.

Total copper concentrations were significantly higher in watershed and SD samples than in ocean samples (RW and OW), indicating the high copper concentrations in RW samples originate from sources on land. Samples collected from copper roof gutters and downspouts revealed higher concentrations of copper than measured in watershed or SD samples. The downspout samples also were dominated by dissolved copper suggesting the high dissolved copper loads in watershed and SD samples arise from rainfall flowing across architectural copper (i.e., derived from buildings and infrastructure).

Stormwater Effects on Receiving Water
Receiving water concentrations of dog, human, and anthropogenic fecal bacteria were significantly associated with SD loads, although other unmeasured factors affecting RW concentrations also were evident. OW also significantly affected RW concentrations of anthropogenic fecal bacteria indicating sources other than the 4th Avenue storm drain.

Estimates of the contributions by SD loads to RW concentrations suggested that stormwater discharges contributed loads of Enterococcus that often exceeded both Ocean Plan and ASBS objectives. While there is no direct comparison between the Enterococcus measurements (CFU/100ml) and animal fecal bacteria (gc/ml) data, it was found that dog, gull, and anthropogenic fecal bacteria from SD exceeded background (10 gc/ml) in several RW samples.

Three of the five samples that could be analyzed for SD effects on RW concentrations exceeded Enterococcus Ocean Plan and ASBS 85th percentile benchmarks. These three samples had low calculated dilution factors for SD discharges that ranged from 3.2 to 5. Two of the exceeding samples were associated with high SD loads of anthropogenic fecal bacteria and both were due to dog fecal bacteria. The third exceeding RW Enterococcus concentration was associated with high gull fecal bacteria. The same three samples that exceeded Enterococcus Ocean Plan or ASBS 85th percentile benchmarks also exceeded the benchmarks for copper concentrations.

These results suggest that management actions aimed at decreasing loads of dog fecal bacteria from the watershed, and in particular subwatershed WS3, should be prioritized to reduce anthropogenic (dog) fecal bacteria. In addition, watershed-wide management actions to reduce loads from architectural copper are needed to reduce copper exceedances in receiving water.

4 Introduction and Background
City of Carmel-by-the-Sea (Carmel) participated in the Central Coast Regional Monitoring Program (Regional Program), for the period 2014-2016, which measured water quality in stormwater discharges and ocean receiving waters in conformance with Special Protections for Areas of Special Biological Significance (ASBS) adopted by the State Water Resources Control Board (SWRCB). The Regional Program identified several exceedances of water quality criteria for copper and fecal indicator bacteria (FIB) associated with stormwater discharged from Carmel into the Carmel Bay ASBS. As a result, Carmel proposed additional follow-up monitoring to help identify the potential sources of the exceedances. This report describes the results from the third and fourth years of monitoring to trace potential sources of FIB exceedances as well as sources (particulate or dissolved) contributing to copper exceedances.

From a regulatory standpoint it is assumed that FIBs detected in stormwater and in ocean receiving water are associated with human fecal waste. However, these FIBs, including Escherichia coli and Enterococcus spp., are present in the intestines of all warm-blooded animals and could come from a variety of different non-human sources. The importance of various sources of fecal bacteria to the FIB signal, typically measured using selective media to culture either E. coli or Enterococcus, is not clear. Parsing anthropogenic (i.e., human and petassociated) sources of fecal matter from wildlife sources (i.e., birds, ruminants, raccoons, etc.) becomes important in situations where there are persistent exceedances of the Ocean Plan guidance for FIBs because studies demonstrate that human health risks associated with wildlife fecal inputs are inherently lower than those associated with human fecal inputs (Schoen and Ashbolt 2010, Soller et al. 2010). Accordingly, the SWRCB has emphasized that dischargers are not responsible for reducing FIBs from wildlife sources. Because the regulatory compliance endpoint is ocean receiving water, which is influenced by fecal inputs from wildlife sources all along the coastal zone, and from within ocean water, it is of interest to determine the fraction of the FIBs measured in ocean water that may be comprised of non-human fecal sources. In addition to potentially being diluted by wildlife FIBs, the anthropogenic FIB signal may be further diluted by cross-reactivity with bacteria endemic to ocean water. This latter concern is particularly associated with fluorescent substrate methods such as Enterolert (Budnick et al. 1996, Adcock and Saint 2001, Sercu et al. 2011).

In order to examine the contribution of anthropogenic sources of FIBs in Carmel’s storm runoff and receiving water, this project used microbial source tracking (MST). This technique takes advantage of the specificity of quantitative polymerase chain reaction (qPCR) probes to unique source bacteria associated with human and other animal fecal matter. A primary objective of this study was to examine whether ocean receiving waters that had Enterococcus exceedances were 1) dominated by human and dog waste sources which were discharged by stormwater, or whether these receiving waters were dominated by 2) wildlife waste sources that were either discharged by stormwater or already present in the ocean water. Furthermore, statistical approaches were used to estimate the maximum human and dog contributions to receiving water Enterococcus concentrations.

A second objective was to trace copper from the watershed to the ocean as previous stormwater sampling has demonstrated ocean receiving water copper concentrations above ATTACHMENT 3

5 Ocean Plan objectives (ASBS report, Applied Marine Sciences, 2016), and to determine the amounts of copper in the dissolved and particulate phases to support decisions about management practices.

Approach
Sites
Since the beginning of the Carmel stormwater monitoring program in 2018, watershed samples have been collected from six locations (Table 1 and Figure 1). Sites WS1, WS3, WS3a, and WS3b were sampled in order to delineate subwatershed areas in WS2 that could account for high concentrations measured in the WS2 discharge. The areas drained by each subwatershed are shown in Figure 2. Samples collected at WS2 include discharges from all subwatersheds and samples collected at WS3 include discharges from WS3a and WS3b. WS2 represents 53% of the entire SD watershed and spans areas both within and outside of the City limits. Subwatersheds WS1 and WS3 represent 40% of the entire WS2 watershed. WS1 collects runoff from outside of the City limits. Subwatersheds WS3a and WS3b account for 73% of the WS3 subwatershed and are located uphill of the only location in the watershed where a sanitary sewer main is located above the storm drain. Sampling to investigate sources of copper was performed in December 2021 and March 2022 at WS2, 4th at Monte Verde, and from downspouts at City Hall, Sunset Center, and Scout House (Figure 1).

Not all sites were sampled in each sampling event (Table 1), and not all analyses were performed in each sample (Appendix A). Sampling at subwatershed WS1 was discontinued after it was deemed to have relatively lower concentrations of dog and human fecal bacteria compared to WS2. Sampling of subwatersheds WS3, WS3a, and WS3b was initiated to identify areas with high contributions to fecal bacteria concentrations in WS2.

Analytical Methods
The following analytical methods were employed on the samples:
1) Enterococcus enumeration was performed on all samples using membrane filtration followed by Enterococcus culturing and enumeration (Messer and Dufour 1998) by Cel Analytical, Inc.
2) qPCR analyses were also performed by Cel Analytical, Inc. on all samples using primers specific to species of the Bacteroidales order associated with dog (DogBact), gull (LeeSeaGull), and human (HF183) feces to quantify the amount of DNA associated with each source (Bernard and Field 2000, Fogarty and Voytek 2005). Human qPCR was performed according to USEPA Method 1696 using human marker HF183 specific to Bacteroides genera. 3) Trace metal (TM) analyses, including total and dissolved trace metal quantification, were performed on all seven sites from all three storms by Physis Environmental Laboratories, Inc.

The amount of copper associated with particulate matter was computed by subtracting dissolved concentrations from total concentrations.

8 Data Analysis
Data analysis began with aggregating data from all sites and all sampling events. This analysis utilized a load index that was calculated by multiplying the concentration (CFU/100ml or gc/ml) in each sample by the watershed acreage (Table 1). Rainfall was not included in the load index because it consists of a single amount applied to all watersheds in each sampling event, it was assumed to affect each watershed equally. Due to the large range in values measured among parameters, data are presented in log-scale graphs.

The sum of data obtained during the monitoring program was analyzed to search for temporal and spatial variation that could uncover the major sources of Enterococcus, fecal indicator bacteria and copper associated with exceedances of Ocean Plan and ASBS water quality benchmarks in nearshore receiving water. Our objective was to cast a wide net that would not disqualify results due to the limited numbers of samples that were available given restricted municipal resources and developing drought conditions. Accordingly, a liberal criterion has been used to qualify a statistical result as significant with a probability of < 0.10.

Average percentages of loads from watersheds and subwatersheds into each successively lower watershed or subwatershed were calculated for each sample to identify the largest upstream sources. This involved calculating mean contributions of SD loads from WS2, mean WS2 contributions from WS1 and WS3, and mean WS3 contributions form WS3a and WS3b. WS2 and WS3 samples were analyzed for differences between samples collected before (T1) and after (T2) the sewer line along Junipero (located upstream of WS3 and downstream of WS3a and WS3b) was relined. Linear regressions were performed to determine whether RW concentrations were significantly influenced by SD and OW. Linear regressions were also used to examine the relationship of SD discharges to RW concentrations and exceedances, as well as to partition effects of SD and OW on RW concentrations.

Results and Discussion
Watershed Loads
Enterococcus and Fecal Bacteria from Dogs, Gulls, and Humans Estimating the contribution of dog and human fecal bacteria to exceedances of Enterococcus in receiving water samples is challenging. It requires establishment of statistical relationships between the qPCR results for dogs + humans and Enterococcus concentrations in stormwater drainages and discharges into the receiving water. Finally, the approximate dilution of storm drain discharges in receiving water samples must be known to estimate the percentage of receiving water Enterococcus due to the storm drain. Moreover, designing management actions to reduce dog + human contributions to exceedances requires information about whether dog or human fecal bacteria predominate in receiving water samples that exceed Enterococcus objectives.

Enterococcus loads from all samples suggested sources distributed broadly over the entire SD watershed (Figure 3). WS2 consistently had the second greatest load of Enterococcus, followed by subwatershed WS3, WS3a, and WS3b, except for the samples from 3/28/22, when SD and ATTACHMENT 3

9 WS2 had lower loads than WS3. WS1 had the lowest load on each of the three dates it was sampled.

Figure 3. Enterococcus load indices for each site.

While gull fecal bacteria were not analyzed as consistently through time as were Enterococcus, they displayed greater spatial and temporal variation than did Enterococcus (Figure 4). Gull fecal bacteria were frequently not detected in WS3 samples and WS2 sometimes had similar or greater loads than did SD.

Figure 4. Gull fecal bacteria load indices for each site.

ATTACHMENT 3

10 Loads of both dog and human (i.e., anthropogenic) fecal bacteria from WS2 were often greater than or similar to loads from SD (Figure 5 and Figure 6). This suggests that there are sources of anthropogenic fecal bacteria throughout the SD watershed, with potent sources in WS2.

ATTACHMENT 3

11 WS3 loads of both dog and human fecal bacteria were sometimes greater than those from WS2 and loads from WS3a and WS3b also sometimes exceeded those from WS3 indicating sources in WS3a and WS3b. Very high loads for human fecal bacteria from WS2 on 3/13/18 suggested a large source. As the municipal sewer line runs above the storm drain under Junipero Street, just uphill from the WS3 sampling location, relining of the sewer line was performed in 2020 after the 3/16/20 sampling event. Both parametric and nonparametric statistical tests revealed that there is no statistically significant difference in mean concentrations between WS2 and WS3 samples collected before and after the infrastructure improvement (Table 3), which is likely due to high variability among samples and low numbers of samples (i.e., 4 samples before and after). Nevertheless, the concentrations of human fecal bacteria measured in WS2 have been orders of magnitude below that measured on 3/13/18.

Tests for the effects of dog, gull, human and anthropogenic fecal bacteria on Enterococcus concentrations in SD samples were performed to determine whether potential effects of receiving water exceedances could be due to one or more of the tested animal sources.

Stepwise linear regressions revealed that concentrations of Enterococcus in SD samples are associated with dog fecal bacteria [Enterococcus CFU/100ml = 110(dog fecal bacteria, gc/ml) + 5072; adjusted R2 = 0.356] and none of the other animal sources of fecal bacteria were significantly associated with Enterococcus concentrations in SD samples.

The contributions to SD loads from WS2 differed substantially among the measured microbial indicators (Table 4). WS2 contributed 46% of Enterococcus loads from SD, which closely matches the percentage of SD watershed covered by WS2 (i.e., 95 acres/180 acres = 53%), confirming the observation from Figure 3 that Enterococcus sources are broadly distributed across the SD watershed. WS2 loads of dog, gull, human, and anthropogenic fecal bacteria were

3.6 – 513,000 times greater than SD loads, further indicating that SD loads of these fecal bacteria largely originate from WS2. Standard errors with magnitudes similar to means reflect large variations among individual values.

Within WS2, loads of Enterococcus and fecal bacteria from WS1 averaged 16% – 36% of WS2 Enterococcus, gull, human, and anthropogenic fecal bacteria loads (Table 4), which are greater ATTACHMENT 3

12 than the 10.5% of WS2 area covered by WS1. Additionally, the average contribution of WS1 dog fecal bacteria to WS2 loads was 72% suggesting it was an important source of dog fecal bacteria. The contribution of WS3 loads to WS2 ranged from 84% for Enterococcus to 257 times greater for gull fecal bacteria. Loads of dog, human, and anthropogenic fecal bacteria from WS3 were 5, 86, and 88 times greater than from WS2, which were all notably greater than the 33% of WS2 covered by WS3.

Copper
Copper loads suggested broadly distributed sources among SD, WS2 and sub watersheds WS3, WS3a, and WS3b (Figure 7). SD always had the greatest loads, followed by WS2, WS3, WS3a, and WS3b. WS2 always had the second highest loads of copper followed by subwatersheds WS3, WS3a, and WS3b. Subwatershed WS1 discharged much smaller loads of copper than the other measured sources.

Percentages of copper in the dissolved fraction ranged from 35 – 88% and exhibited an inverse spatial pattern, compared to total copper (Figure 8). SD often had the lowest percentage of dissolved copper suggesting higher particulate loads compared to WS2 and its subwatersheds.

As with Enterococcus, the percentages of SD copper loads coming from WS2 were comparable to the respective watershed areas (i.e., WS2 = 53% of SD; Table 5). WS1 had much smaller loads of copper that would be expected if its load were proportional to area (i.e., 10% of WS2). The percentage of WS2 copper loads contributed by WS3 were marginally greater than the 32% expected if loads were proportional to watershed area. Copper loads from WS3a and WS3b into WS3 were greater than 33% and 40% expected if loads were proportional to watershed area.

High concentrations of dissolved copper have historically been linked to architectural copper (Arnold 2005, Pennington and Webster-Brown 2008, Kelly et al. 2011). The preponderance of dissolved copper in Carmel stormwater discharges suggests architectural sources. To investigate this possibility, samples were collected during a storm that dropped 0.9 inches of rainfall on 12/23/2021 from downspouts at three locations: Sunset Center (on Mission Street between 8th Avenue and 10th Avenue), City Hall (on Monte Verde Street between Ocean Avenue and 7th Avenue), and Scout House (at Mission Street and 8th Avenue). Sunset Center and City Hall have copper gutters and downspouts, and Scout House has aluminum gutters and downspouts.

Rainwater coming from copper gutters and downspouts at City Hall and Sunset House had six to ten times the copper concentrations as compared to the sample from Scout House (Table 6).

Samples collected several days after rainfall at two watershed locations had much lower copper concentrations, which were still dominated by dissolved copper at levels consistent with storm samples from all sites (Figure 8).

15 Effects of SD loads on Receiving Water Concentrations Receiving water concentrations of Enterococcus consistently exceeded both ASBS and Ocean Plan objectives from 2018 until March 2021, whereas neither sample collected since then exceeded either objective (Figure 9). Ocean water samples collected away from the direct influence of the storm drain discharge also exceeded one or both Enterococcus water quality objectives between January 2019 and January 2021, indicating background Enterococcus emanating from sources distant from SD.

Figure 9. Concentrations of Enterococcus in Receiving Water and Ocean Water samples adjacent Carmel 4th Avenue storm drain.

Linear regressions were performed to investigate whether SD and/or OW concentrations of Enterococcus, dog, gull, human, and anthropogenic fecal bacteria affected RW concentrations.

SD concentrations were found to affect RW concentrations of dog, human and anthropogenic fecal bacteria (Table 7). RW concentrations of anthropogenic fecal bacteria were also significantly associated with concentrations at OW (Table 7). An absence of effects on RW Enterococcus concentrations by either SD or OW suggest a variety of sources not associated with storm runoff.

Estimates of the contributions of SD loads to Enterococcus (CFU/100ml), dog, gull, human, anthropogenic fecal bacteria (gc/ml), and copper concentrations at RW were made by calculating the dilution of SD discharges in each RW sample using dissolved copper concentrations as a conservative parameter (Table 8). Unlike Enterococcus and fecal bacteria, copper concentrations were orders of magnitude lower in RW and OW samples than in SD samples (Appendix A). This characteristic of copper, and primarily dissolved copper, makes it ideal for calculating the dilution of SD water in each RW sample. Five sampling events since 3/13/2018 included measurements of dissolved copper at RW (Table 8). SD dilution in these five RW samples resulted in estimated RW Enterococcus derived from SD ranging from 0 – 4975 CFU/100ml, with three values >3500 CFU/ml.

17 To determine whether the estimated contributions of SD Enterococcus to RW could be sufficient to cause RW exceedances, the SD contributions were subtracted from measured RW concentrations. This revealed that on 3/13/18 a reduction of RW Enterococcus concentrations by 3577 would have left 4217 CFU/100ml which exceeds the Ocean Plan by an order of magnitude, suggesting potent sources in OW. On 1/28/21 and 3/10/21, subtraction of the estimated SD contributions to RW Enterococcus concentrations would have resulted in values of -3475 and -670, respectively suggesting the RW exceedances on these dates could have been due largely to SD contributions.

Measuring the contribution to Enterococcus concentrations by fecal bacteria quantified with qPCR would be necessary to unequivocally determine the anthropogenic component in Enterococcus Ocean Plan and ASBS exceedances. Because there is no direct correspondence between Enterococcus CFU/100ml and dog, gull, or human fecal bacteria measured by qPCR methods, diluted SD gc/ml values estimated in RW samples were screened for those data that represented values clearly above background, which was arbitrarily set at 10 gc/ml.

RW dog fecal bacteria had the two highest estimated contributions from SD (i.e., Table 11; 43 gc/ml on 3/13/2018 and 20 gc/ml on 1/28/2021). Gull fecal bacteria at RW had the 3rd and 4th- highest contributions from SD (i.e., 16 gc/ml on 3/10/2021 and 13 gc/ml on 12/13/2021). There were no estimated contributions to RW concentrations of human fecal bacteria from SD above background concentrations. This observation is especially notable for the sample from 3/13/2018, when WS2 had a concentration of human fecal bacteria of 3779 gc/ml, whereas WS1 and SD both had no human fecal bacteria detected (Appendix A). The above-background contributions of SD anthropogenic fecal bacteria to RW concentrations were both due to dog fecal bacteria. While SD discharges delivered diluted concentrations of Enterococcus to RW that exceeded Ocean Plan and ASBS objectives, the only anthropogenic fecal bacteria above background were derived from dogs. Moreover, the broad distribution of Enterococcus sources in the SD watershed and the low amount of variation in SD Enterococcus loads due to significant associations with WS2 dog fecal bacteria suggest that reducing WS2 dog fecal bacteria would be unlikely to make a large difference in SD Enterococcus loads.

RW concentrations of total copper due to SD discharges exceeded either the Ocean Plan or the ASBS objective in 50% of samples since 3/1/2018, but not since 3/10/2021 (Table 16). The only Ocean Plan exceedance occurred on 3/18/2018 and the ASBS 85th percentile was exceeded on 1/28/2021 and 3/10/2021 (Table 16).

Conclusions
Watershed Loads and Sources
Contributions of loads from WS2 to SD differed among fecal indicators. On average, WS2 contributed 46% of Enterococcus loads from SD, indicating broadly distributed sources across the entire SD watershed. Loads of dog, gull, human, and anthropogenic fecal bacteria from WS2 averaged 4 – 51,000 times greater than loads from SD, indicating potent sources for these fecal bacteria within WS2. WS1 loads of dog fecal bacteria averaged 72% of WS2 loads and none of the other fecal bacteria loads from WS1 exceeded 27% of WS2 loads, suggesting the ATTACHMENT 3

18 WS1 could be an important source of dog fecal bacteria. Contributions of Enterococcus, gull, and human fecal bacteria loads from WS3 to WS2 averaged 84%, 13%, and 48%, respectively.

Loads of dog and anthropogenic fecal indicators from subwatershed WS3 were 5.1 and 2.4 times greater than from WS2, identifying WS3 as a major contributor of these indicators into WS2 and SD. Loads of dog and human fecal bacteria from WS3a averaged 2 – 24 times greater than those from WS3. Dog and gull fecal bacteria were not measured in WS3b, but loads of human fecal bacteria from this subwatershed averaged 45 times greater than from WS3. These results identify WS3a, and WS3b as important subwatersheds for management actions to reduce loads of dog, human, and anthropogenic fecal bacteria into SD.

Following high concentrations of human fecal bacteria in WS2 on 3/13/18, the sewer line under Junipero Street between 1st Avenue and 2nd Avenue was relined in mid 2020.

Concentrations of human fecal bacteria before (T1) and after (T2) the sewer was relined were not statistically different, likely due to small numbers of samples, but concentrations in T2 remained several orders of magnitude below the value seen on 3/13/18. Robust concentrations of human fecal bacteria in WS3, WS3a, and WS3b suggest continuing sources of human fecal bacteria in those subwatersheds.

Copper loads from WS2 averaged 50% of those from SD, indicating broadly distributed sources within the entire SD watershed. Copper loads from WS3 averaged <40% of WS2 loads, which is also consistent with broadly distributed sources.

Total copper concentrations were significantly higher in watershed and SD samples than in ocean samples (RW and OW), indicating the high copper concentrations in RW samples originate from sources on land. Samples collected from copper roof gutters and downspouts revealed higher concentrations of copper than measured in watershed or SD samples. The downspout samples also were dominated by dissolved copper suggesting the high dissolved copper loads in watershed and SD samples arise from rainfall flowing across architectural copper (i.e., derived from buildings and infrastructure).

Stormwater Effects on Receiving Water
Receiving water concentrations of dog, human, and anthropogenic fecal bacteria were significantly associated with SD loads, although other unmeasured factors also were evident.

OW also significantly affected RW concentrations of anthropogenic fecal bacteria indicating sources other than the 4th Avenue storm drain.

Estimates of the contributions by SD loads to RW concentrations suggested that stormwater discharges contributed loads of Enterococcus that often exceeded both Ocean Plan and ASBS objectives. While there is no direct comparison between CFU/100ml and gc/ml data, it was found that dog, gull, and anthropogenic fecal bacteria from SD exceeded background (10 gc/ml) in several RW samples. Three of the five samples that could be analyzed for SD effects on RW concentrations exceeded Enterococcus Ocean Plan and ASBS 85th percentile benchmarks. These three samples had low calculated dilution factors for SD discharges that ranged from 3.2 to 5.

Two of the exceeding samples were associated with high SD loads of anthropogenic fecal bacteria and both were due to dog fecal bacteria. The third exceeding RW Enterococcus ATTACHMENT 3

19 concentration was associated with high gull fecal bacteria. The same three samples that exceeded Enterococcus Ocean Plan or ASBS 85th percentile benchmarks also exceeded the benchmarks for copper concentrations. These results suggest that management actions aimed at decreasing loads of dog fecal bacteria from the watershed, and in particular subwatershed WS3, should be prioritized to reduce anthropogenic (dog) fecal bacteria. Additionally, watershed-wide management actions are needed to reduce copper exceedances in receiving water. Nevertheless, the broad distribution of Enterococcus sources in the SD watershed and the low amount of variation in SD Enterococcus loads due to significant associations with WS2 dog fecal bacteria suggest that reducing WS2 dog fecal bacteria would be unlikely to make a large difference in SD Enterococcus loads.

Recommendations
● Consideration should be given to reinstituting sampling at WS1 to document whether it remains a source of dog and human fecal bacteria to WS2. ● Management actions should be developed to reduce loads of dog fecal bacteria in the watershed .
● Integrity of sewer laterals in WS3 should be investigated to determine the sources and remedies for high human fecal bacteria coming from WS3a and WS3b. ● Management actions should be implemented to reduce the use of architectural copper. ● Discussions should be held with stormwater regulators to apprise them of these management actions and obtain assurances that reductions in anthropogenic fecal bacteria will relieve any regulatory burden in the absence of reductions in SD Enterococcus loads.

New Palo Alto Ordinance Prohibits
Copper Roofing Materials
January 2003
Rain runoff from buildings and streets picks up copper and other pollutants. This runoff flows untreated into creeks and the Bay resulting in thousands of pounds of copper entering the Bay each year. The sources of copper include vehicle brake pads, automotive fluids, wash waters, and architectural building materials.

In 1999 and 2000, the City of Palo Alto's Regional Water Quality Control Plant (RWQCP) studied the impacts of architectural copper on stormwater pollution. The results are summarized in the document "Architectural Uses of Copper: An Evaluation of Storm Water Pollution Loads and BMPs."1
Some of the more important conclusionsinclude:
 The amount of copper released per year from copper roofs in the RWQCP service area is estimated to be greater than the annual industrial copper dischargesto the RWQCP.  An incremental increase of 1000 square feet of copper roofing can lead to, by itself, a copper concentration in a creek during an average rainfall that equalsthe chronic toxicity criteria established by the U.S. Environmental Protection Agency.

Although it is difficult to predict the fate of copper in roof runoff, it is clear that copper in the runoff is in concentrations known to be toxic to aquatic life. Currently, there are no practical or effective ways to prevent copper from washing off of copper roofs or to remove copper from roof runoff. Therefore, in August 2002, the City of Palo Alto adopted an ordinance prohibiting the use of copper-containing roofing materials, shingles, and gutters in new buildings, and to prohibit their use for replacement of roofs except in historic buildings.

Ordinance Text (Municipal Code Section 16.09.160(b)) 2
(b) Copper roofing materials. On and after January 1, 2003, copper metal roofing, copper granule containing asphalt shingles and copper gutters shall not be permitted for use on any residential, commercial or industrial building for which a building permit is required.

Copper flashing for use under tiles or slates and small copper ornaments are exempt from this prohibition. Replacement roofing and gutters on historic structures are exempt, provided that the roofing material used shall be prepatinated at the factory. For the purposes of this exemption, the definition of "historic" shall be limited to structures designated as Category 1 or Category 2 buildings in the current edition of the Palo Alto Historical and Architectural Resources Report and Inventory. 1 Document available athttp://www.cityofpaloalto.org/public-works/documents/cb-ArchitectCu.pdf 2 Palo Alto Municipal Ordinance is available at www.city.palo-alto.ca.us/government/municipalcode.html.

Scroll down to Title 16. Chapter 16.09 is Sewer Use Ordinance. See Section 16.09.160(b) for this ordinance.

RE: Stormwater Monitoring Results from 2022 – 2023
Two storms were sampled during the 2022 – 2023 rainfall season. The first sampled storm occurred on 12/27/2022, and the second storm was sampled on 3/21/2023. Rainfall for each storm is shown in Table 1. In each storm, samples were collected from seven sites, shown in Figure 1.

Samples were analyzed for dissolved copper and concentrations of Enterococcus and biomarkers for dog and human fecal material. Analysis of copper was performed by Physis ATTACHMENT 6

2 Environmental Laboratories, Anaheim, CA, and analysis of bacteria and fecal indicators was performed by Cel Analytical, San Francisco, CA.

The point of compliance for stormwater discharges is receiving water. Determining the effects of storm drain discharge on receiving water requires estimates of increased concentrations in receiving water due to storm drain discharges. Increased receiving water concentrations due to storm drain discharges were estimated for each storm by using dissolved copper in storm drain samples as a conservative parameter (Table 2). The concentration of dissolved copper at the ocean water site, distant from the receiving water collection site, was taken as the background concentration at the time of sample collection. The ocean water concentration of dissolved copper was subtracted from the concentration at the receiving water site and the remainder was assumed to be the concentration added to the receiving water sample by the storm drain discharge. The dilution factor of storm drain water in the receiving water samples was then calculated by dividing the storm drain concentrations by the receiving water concentration minus the ocean concentration. This dilution factor was then used to estimate the amount of Enterococcus and dog, human, and dog + human (total anthropogenic) fecal indicators in the receiving water samples originating from the storm drain. The dilution factor for storm drain effects on receiving water concentrations was 3.05 on 12/27/2023 and 2650 on 3/21/2023 (Table 2).

Application of the estimated dilution factors for each storm to corresponding concentrations of Enterococcus and dog, human, and total anthropogenic fecal indicators revealed that the greatest effect of the storm drain discharge occurred during the 12/27/2022 storm, with a dilution factor of 3.05. Storm drain Enterococcus were estimated to have contributed 655 CFU/100 ml of the total 2000 CFU/10 ml concentration in receiving water (Table 3). Compared to the 85th percentile reference concentration for Enterococcus measured during the Central Coast Regional ASBS monitoring program (i.e., 229 CFU/100 ml; Applied Marine Sciences, 2016), it is likely that the 85th percentile would have been exceeded on 12/27/2022 due to the storm drain discharge, in the absence of background ocean concentrations. Moreover, robust storm drain concentrations of dog, human and anthropogenic fecal indicators suggest that anthropogenic sources of fecal material could have contributed to the receiving water Enterococcus concentrations. Notably, three-fold higher storm drain concentrations of Enterococcus in the 3/21/2023 storm than in the 12/27/2022 storm were not associated with high receiving water concentrations, consistent with the high dilution factor calculated for the ATTACHMENT 6

3 storm drain discharge on 3/21/2023 (i.e., 2650; Table 2). Dynamic ocean conditions and large waves breaking on the shore during sampling on 3/21/2023 probably account for the high dilution factor.

Watershed and subwater samples were collected in each storm to help define areas making the greatest contributions to storm drain loads of Enterococcus, dog and human fecal indicators. In the first storm, WS2 had the highest concentrations of Enterococcus and all measured fecal indicators (Table 4). In this storm, WS3 had concentrations of Enterococcus similar to WS2 but none of the fecal indicators were detected coming from WS3, although human fecal indicators were detected in two of its subwatersheds.

4 Summary
Differences in the timing of rainfall and ocean conditions, relative to sample collection, likely modify effects of storm drain discharges on ocean receiving water concentrations. On 12/27/2022, following a 10-day period without rainfall, increased receiving water concentrations revealed a 3:1 dilution of the storm drain discharge. The estimated contribution of storm drain Enterococcus to receiving water would have caused an exceedance of the ASBS 85th percentile threshold in the absence of a background ocean concentration. WS2 continues to be a source of Enterococcus, dog and human fecal indicators to the 4th Avenue storm drain discharge.

RE: Stormwater Monitoring Results from 2023 – 2024
Consistent with actions proposed in the City of Carmel by the Sea (the City) stormwater Compliance Plan for Areas of Special Biological Significance (ASBS), two storms were sampled during the 2023-2024 rainfall season to measure fecal indicator bacteria and dissolved copper concentrations from stormwater discharged into the ocean. The first sampled storm occurred on 1/22/2024, and the second storm was sampled on 2/01/2024. In each storm, samples were collected from eight sites; watersheds 2 and 3 (WS2, WS3), subwatersheds 3a and 3b (WS3a, WS3b), the 4th Ave storm drain (SD), receiving water (RW), and 2 ocean water sites (OW, OW2), shown in Figure 1. Rainfall for each storm is shown in Table 1.

Determining the effects of storm drain discharge on receiving water requires estimates of increased concentrations in receiving water due to storm drain discharges.

This dilution factor was then used to estimate the amount of Enterococcus and dog, human, and dog + human (total anthropogenic) fecal indicators in the receiving water samples originating from the storm drain. Storm drain dissolved copper concentrations were higher than ocean water concentrations during both storms (Figure 2). The dilution factor for storm drain effects on receiving water concentrations was 31,800 on 1/22/2024 and 287.95 on 2/01/2024 (Table 2).

Application of the estimated dilution factors for each storm to corresponding concentrations of Enterococcus and dog, human, and total anthropogenic fecal indicators revealed that the greatest effect of the storm drain discharge occurred during the 2/01/2024 storm, with a dilution factor of 287.95. Storm drain Enterococcus were estimated to have contributed 0.786 CFU/100 ml of the total 25,000 CFU/100 ml concentration in receiving water (Table 3).

Human fecal indicators in the storm drain were tenfold higher during the 1/22/2024 storm than in the 2/01/2024 (Table 3). Moreover, storm drain concentrations of anthropogenic fecal indicators on 1/22/2024 suggest that anthropogenic sources of fecal material could have contributed to the receiving water Enterococcus concentrations (Figure 3).

Ten-day antecedent ocean conditions were comparable during both storm events. Significant wave height and dominant wave period were averaged both 10 days prior to sampling, and day of sampling. Significant wave height was 2 time larger during the second storm than during the first. Wave period was longer during the second storm as well. Although effects of the different ocean conditions on the dilution factors were not observed between storms, dynamic winter conditions may have influenced the dilution factors for both storms. Day-of-sampling rainfall, as well as antecedent rain levels, were higher for storm 2 which may explain the reduced indicator bacteria concentrations for the second storm.

5 Watershed and subwatershed samples were collected in each storm to help define areas making the greatest contributions to storm drain loads of Enterococcus, dog and human fecal indicators. In the first storm, WS2 had the highest concentrations of Enterococcus, whereas subwatershed WS3b had the highest dog and combined anthropogenic fecal indicators measured. Human indicators were greatest at WS3 during the first storm, but not detected in the same watershed during the second storm (Table 4). The detection of human indicators in WS3 while none were detected in WS3a or WS3b suggests that there are sources of human fecal bacteria entering the drainage along 2nd Avenue between Torres Avenue and Forest Hill Park. Dog indicators were not detected in any of the watersheds during storm 2. Watershed 3 and both subwatershed Enterococcus concentrations were comparably high for both storms.

However, storm drain Enterococcus levels were substantially higher during the first storm (Figure 4), implying there are other sources of Enterococcus flowing into the storm drain.

Summary
Differences in the timing of rainfall and ocean conditions, relative to sample collection, likely modify effects of storm drain discharges on ocean receiving water concentrations. Heavy rainfall on 2/01/2024, and following a 10-day period of rainfall, diluted the storm drain discharge compared to the 1/22/2024 storm. The estimated contribution of storm drain Enterococcus to receiving water did not exceed the ASBS 85th percentile threshold (229 MPN/100ml) during either storm. All watersheds appear to be a source of Enterococcus, and anthropogenic fecal indicators to the 4th Avenue storm drain discharge, although human indicators were only detected in WS2 and WS3, and dog indicators were only detected in the first storm.

Curb Painting:

Subsequent to the adoption of Ordinance No. 2024-002, the City painted the curbs red to prohibit parking as required by CVC 22500 (n) within 20 feet of the vehicle approach side of any marked or unmarked crosswalk or within 15 feet of any crosswalk where a curb extension is present.

In addition, the City painted the curbs yellow in the locations listed in City Municipal Code Section10.36.010 Subsection (C)(1) with black lettering reading “Commercial Loading 20 Minutes Only”.

B. AB 43 (Traffic Safety)
AB 43 was signed by the Governor on October 8, 2021 and became effective on January 1, 2022 (Attachment 4). AB 43 amended several Sections of the California Vehicle Code and also added Sections relating to traffic safety.

CVC 22358 is one of the Sections amended by AB 43 and now reads:
§ 22358. Decrease of local limits
(a) Whenever a local authority determines upon the basis of an engineering and traffic survey that the limit of 65 miles per hour is more than is reasonable or safe upon any portion of any street other than a state highway where the limit of 65 miles per hour is applicable, the local authority may by ordinance determine and declare a prima facie speed limit of 60, 55, 50, 45, 40, 35, 30, 25, 20, or 15 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, which declared prima facie limit shall be effective when appropriate signs giving notice thereof are erected upon the street. (b) This section shall become operative on the date specified in subdivision (c) of Section 22366.

Section 22358 became effective on January 3, 1996.

C. Carmel Municipal Code (CMC) Chapter 10.12 ( Speed Limits)

CMC Chapter 10.12 contains the speed limits which have been codified in the Municipal Code with some streets designated as 15 miles per hour, one street (San Antonio) as 20 miles per hour and a number of streets as 25 miles per hour.

If the City were to consider changing the speed limits for some streets, then an ordinance would be necessary to identify which streets and the corresponding speed limit.

D. Traffic Study
As noted above, CVC 22500 (n), the Daylight Law, allows a City to adopt an ordinance to establish a different distance than specified in Section 22500 provided that the ordinance includes a finding that the different distance is justified by established traffic safety standards.

As also noted, CVC § 22358 (Decrease of local limits), allows a City to adopt an ordinance “upon the basis of an engineering and traffic survey” with a speed limit ranging from 15 miles per hour to 60 miles per hour “whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, which declared prima facie limit shall be effective when appropriate signs giving notice thereof are erected upon the street.”
E. Conclusion
In order to conduct a traffic study for either of the purposes specified in CVC 22500 (n) and/or CVC § 22358, the City would need to retain a qualified traffic engineer.

If the traffic study supported reducing the speed limit on certain streets pursuant to CVC § 22358, then it is possible that the speed limit reduction might be considered by the City in evaluating what changes, if any, might be appropriate under CVC 22500 (n) for those streets which could result in additional parking spaces being available if the distance currently painted red is reduced below 20 feet. The traffic study could also include a review of the locations designated for Commercial Loading.

However, the City would need to review the traffic study to determine what options, if any, would be appropriate for a potential ordinance or ordinances pursuant to CVC 22500 (n) and/or CVC § 22358.

FISCAL IMPACT:

No fiscal impact for this Agenda item. If the City Council gives direction to City Administrator to retain a traffic engineer to conduct a study, then there will be a fiscal impact depending upon the cost for the study.

PRIOR CITY COUNCIL ACTION:

City Council meetings regarding AB 413 held on October 1, 2024 and November 5,

2024 (first reading of Ordinance No. 2024-002) and December 3, 2024 (second reading of Ordinance No. 2024-002).

Assembly Bill No. 413
CHAPTER 652
An act to amend Section 22500 of the Vehicle Code, relating to vehicles. [ Approved by Governor October 10, 2023. Filed with Secretary of State October 10, 2023. ]

LEGISLATIVE COUNSEL'S DIGEST
AB 413, Lee. Vehicles: stopping, standing, and parking.

Existing law prohibits the stopping, standing, or parking of a vehicle in certain places and under certain conditions, including within an intersection, on a sidewalk or crosswalk, or in front of a fire station. Existing law additionally authorizes local jurisdictions to, by ordinance, restrict parking in certain areas, at certain times, and for certain reasons, and to establish metered parking.

This bill would prohibit the stopping, standing, or parking of a vehicle within 20 feet of the vehicle approach side of any unmarked or marked crosswalk or 15 feet of any crosswalk where a curb extension is present, as specified. The bill would, prior to January 1, 2025, authorize jurisdictions to only issue a warning for a violation, and would prohibit them from issuing a citation for a violation, unless the violation occurs in an area marked using paint or a sign.

By restricting parking in certain areas, this bill would impose a state-mandated local program.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.

Digest Key
Vote: MAJORITY Appropriation: NO Fiscal Committee: YES Local Program: YES Bill Text
The people of the State of California do enact as follows:

ATTACHMENT 1.1
(AB 413 Text)

SECTION 1.

Section 22500 of the Vehicle Code is amended to read:
22500.

A person shall not stop, park, or leave standing any vehicle whether attended or unattended, except when necessary to avoid conflict with other traffic or in compliance with the directions of a peace officer or official traffic control device, in any of the following places:
(a) Within an intersection, except adjacent to curbs as may be permitted by local ordinance. (b) On a crosswalk, except that a bus engaged as a common carrier or a taxicab may stop in an unmarked crosswalk to load or unload passengers when authorized by the legislative body of a city pursuant to an ordinance.
(c) Between a safety zone and the adjacent right-hand curb or within the area between the zone and the curb as may be indicated by a sign or red paint on the curb, which sign or paint was erected or placed by local authorities pursuant to an ordinance.

(e) (1) In front of a public or private driveway, except that a bus engaged as a common carrier, schoolbus, or a taxicab may stop to load or unload passengers when authorized by local authorities pursuant to an ordinance.
(2) In unincorporated territory, where the entrance of a private road or driveway is not delineated by an opening in a curb or by other curb construction, so much of the surface of the ground as is paved, surfaced, or otherwise plainly marked by vehicle use as a private road or driveway entrance, shall constitute a driveway.
(f) On a portion of a sidewalk, or with the body of the vehicle extending over a portion of a sidewalk, except electric carts when authorized by local ordinance, as specified in Section 21114.5. Lights, mirrors, or devices that are required to be mounted upon a vehicle under this code may extend from the body of the vehicle over the sidewalk to a distance of not more than 10 inches. (g) Alongside or opposite a street or highway excavation or obstruction when stopping, standing, or parking would obstruct traffic.
(h) On the roadway side of a vehicle stopped, parked, or standing at the curb or edge of a highway, except for a schoolbus when stopped to load or unload pupils in a business or residence district where the speed limit is 25 miles per hour or less.
(i) Except as provided under Section 22500.5, alongside curb space authorized for the loading and unloading of passengers of a bus engaged as a common carrier in local transportation when indicated by a sign or red paint on the curb erected or painted by local authorities pursuant to an ordinance.

Local authorities, by ordinance or resolution, may permit parking on these bridges on state highways in their respective jurisdictions if the ordinance or resolution is first approved in writing by the Department of Transportation. Parking shall not be permitted unless there are signs in place, as may be necessary, to indicate the provisions of local ordinances or the order of the Department of Transportation.
(l) In front of or upon that portion of a curb that has been cut down, lowered, or constructed to provide wheelchair accessibility to the sidewalk.
(m) In a portion of a highway that has been designated for the exclusive use of public transit buses.

(2) Notwithstanding paragraph (1), a local authority may permit commercial vehicle loading or unloading within 20 feet of the vehicle approach side of any marked or unmarked crosswalk or within 15 feet of any crosswalk where a curb extension is present if both of the following requirements are met:
(A) A local authority authorizes the commercial vehicle loading and unloading by ordinance and identifies the crosswalk or crosswalks in the ordinance. (B) A local authority has marked the commercial loading and unloading areas with paint or signage. (3) Notwithstanding paragraph (1), a local authority may permit parking for bicycles or motorized scooters within 20 feet of a crosswalk.

CITY OF CARMEL-BY-THE-SEA

CITY COUNCIL
ORDINANCE NO. 2024-002

AN ORDINANCE OF THE CITY COUNCIL OF CARMEL-BY-THE-SEA AMENDING CHAPTER

10.36.010 OF THE CARMEL-BY-THE-SEA MUNICIPAL CODE BY ADDING SUBSECTION (1), UNDER SECTION (C); IDENTIFYING COMMERCIAL LOADING ZONES TO COMPLY WITH CVC 22500 AND ASSEMBLY BILL 413-THE "DAYLIGHTING BILL"
WHEREAS, on October 2023, Governor Gavin Newson signed Assembly Bill 413 (AB 413) into law, which aims to increase visibility at crosswalks across California; and WHEREAS, AB 413 went into effect January 1, 2024, and enforcement is required to begin on January 1, 2025; and
WHEREAS, AB 413, also known as the “Daylighting Bill,” adds adds subdivision (n) to the existing California Vehicle Code section 22500: Stopping, Standing and Parking, generally prohibiting the stopping, standing, or parking of a vehicle within 20 feet of the vehicle approach side of any marked or unmarked crosswalk, or within 15 feet of any crosswalk where a curb extension is present; and
WHEREAS, AB 413 allows local authority to permit commercial loading or unloading in areas impacted by AB 413 if the local authority: (a) authorizes the commercial vehicle loading and unloading by ordinance and identifies the specific locations in the ordinance; and (b) marks the commercial loading and unloading zones with paint or signage; and WHEREAS, the Traffic Safety Committee (TSC) has analyzed accident data for the City from the past six years and has identified intersections that have the highest probability for pedestrian versus vehicle accidents, determined the number of parking spaces in the business district, and have come up with a plan to convert certain areas into loading zones in compliance with AB 413; and
WHEREAS, on August 28, 2024, the TSC presented the draft AB 413 Parking Plan to the public, and on October 1, 2024, the TSC presented the plan to City Council; and WHEREAS, the proposed AB 413 Parking Plan brings the City into compliance with AB 413 and allows for flexibility based on future needs of the City while limiting the impact on the City’s existing available parking. Future changes to the plan would be made by the TSC, unless required to be made through the City Council; and
WHEREAS, the City Council gave direction to staff on October 1, 2024 to return with a draft ordinance amending Carmel-by-the-Sea Municipal Code Chapter 10.36.010 “Loading Zones” to identify the areas converted to Commercial Loading Zones and to begin implementation of the proposed parking plan associated with AB 413.

Attachment 1
ATTACHMENT 2

Ordinance No. 2024-002

THE CITY COUNCIL OF THE CITY OF CARMEL-BY-THE-SEA HEREBY ORDAIN AS FOLLOWS:

SECTION 1. Chapter 10.36.010 is hereby amended, to add Subsection (C)(1) as follows:

10.36.010 Loading Zones – Indication.

A. The City Council is authorized to determine and to mark loading zones as follows:

SECTION 2. Environmental Determination. The proposed amendments are categorically exempt from the provisions of the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15304 (exemption for minor alterations to land) because restriping of pavement, painting curbs, and related actions to implement the commercial loading restrictions are minor alterations in the condition of land that do not involve removal of healthy, mature, scenic trees. The proposed amendments are also categorically exempt from CEQA pursuant to CEQA Guidelines section 15301 (Class 1 Existing Facilities exemption) because restriping of pavement, painting curbs, and related actions are minor alterations of existing public facilities that involve no expansion of existing or former use. Further, none of the exceptions to the use of a categorical exception as set forth in CEQA Guidelines section 15300.2 apply to these improvements. Additionally, this matter does not have the potential for causing a significant effect on the environment, pursuant to Section 15061(b)(3) of the CEQA Guidelines, because it does not have a potential for resulting in either a direct physical change in the environment or a reasonably foreseeable indirect physical change in the environment and involves only general policy and procedure making.

SECTION 3. Severability. If any section, subsection, provision, sentence, clause, phrase or word of this Ordinance is for any reason held to be illegal or otherwise invalid by any court of competent jurisdiction, such invalidity shall be severable, and shall not affect or impair any remaining sections, subsections, provisions, sentences, clauses, phrases or words of this Ordinance.

SECTION 4. Effective Date. This Ordinance shall take effect 30 days after its adoption by the City Council of the City of Carmel-by-the-Sea.

WHEREAS, on October 2023, Governor Gavin Newson signed Assembly Bill 413 (AB 413) into law, which aims to increase visibility at crosswalks across California; and WHEREAS, AB 413 went into effect January 1, 2024, and enforcement is required to begin on January 1, 2025; and
WHEREAS, AB 413, also known as the "Daylighting Bill," adds adds subdivision (n) to the existing California Vehicle Code section 22500: Stopping, Standing and Parking, generally prohibiting the stopping, standing, or parking of a vehicle within 20 feet of the vehicle approach side of any marked or unmarked crosswalk, or within 15 feet of any crosswalk where a curb extension is present; and
WHEREAS, AB 413 allows local authority to permit commercial loading or unloading in areas impacted by AB 413 if the local authority: (a) authorizes the commercial vehicle loading and unloading by ordinance and identifies the specific locations in the ordinance; and (b) marks the commercial loading and unloadir,g zones with paint or signage; and WHEREAS, the Traffic Safety Committee (TSC) has analyzed accident data for the City from the past six years and has identified intersections that have the highest probability for pedestrian versus vehicle accidents, determined the number of parking spaces in the business district, and have come up with a plan to convert certain areas into loading zones in compliance with AB 413; and
WHEREAS, on August 28, 2024, the TSC presented the draft AB 413 Parking Plan to the public, and on October 1, 2024, the TSC presented the plan to City Council; and WHEREAS, the proposed AB 413 Parking Plan brings the City into compliance with AB 413 and allows for flexibility based on future needs of the City while limiting the impact on the City's existing available parking. Future changes to the plan would be made by the TSC, unless required to be made through the City Council; and
WHEREAS, the City Council gave direction to staff on October 1, 2024 to return with a draft ordinance amending Carmel-by-the-Sea Municipal Code Chapter 10.36.010 "Loading Zones" to identify the areas converted to Commercial Loading Zones and to begin implementation of the proposed parking plan associated with AB 413.
