2024 財政年度街道與人行道標準年度報告
年度報告的主要發現
該年度報告涵蓋了2023 年7 月至2024 年6 月期間2,600 多項現場評估的結果。包括社區層面的調查結果和比較311 服務請求。主要發現
The following report details results from Street and Sidewalk Maintenance Standards, which are objective evaluations of the cleanliness and condition of San Francisco’s streets and sidewalks. The City Charter requires the Controller’s Office (CON) to develop and evaluate these maintenance standards and report out on the City’s condition under the standards. The current standards were developed by CON in 2018 with input from the San Francisco Department of Public Works (Public Works), and evaluate litter, dumping, graffiti, feces, as well as other health hazards and sidewalk issues.
This report covers the results of over 2,600 in-person evaluations over twelve months of data collection between July 2023 and June 2024, as well as comparing results to those in prior years. The report begins with a discussion of key findings from high-salience cleanliness issues, then compares findings in neighborhoods across the city. This is followed with additional detailed analysis of the standards. The last section of the report compares results from 311 service requests to CON’s evaluations of the Street and Sidewalk Maintenance Standards.
The table below shows the main results of evaluations of the standards and the following section provides additional analysis. For more detailed information on the Maintenance Standards and data collection see the program Reference Manual and Appendices. For citywide and neighborhood dashboards visit the Street and Sidewalk Maintenance Standards dashboards.
Results for high salience standards categories and changes from previous period
Sidewalk litter citywide decreased slightly from the prior year
Sidewalk litter decreased slightly citywide between January-June 2023 and July 2023-June 2024, but levels increased some in the last six months of that period. On the five-point scale used to measure litter, average sidewalk litter levels remain between a “few traces of litter” (Litter level = 2) to “More than a few traces” (Litter level = 3). The visual below shows this stability over time.
Most evaluated sidewalk segments have some litter. It’s rarer to see a sidewalk either completely free of litter or with significant accumulation. This trend holds true over time and across neighborhoods.
| Litter Level | Litter description |
|---|---|
1 | None - the sidewalk is free of litter |
2 | A few traces - the sidewalk is predominantly free of litter except for a few small traces |
3 | More than a few traces but no accumulation - there are no piles of litter, and there are large gaps between pieces of litter |
4 | Distributed litter with some accumulation - there may either be large gaps between piles of litter or small gaps between pieces of litter |
5 | Widespread litter with significant accumulation |
2022-2024 年全市人行道平均垃圾水平
街道垃圾與人行道垃圾的模式相同
此標準對街道上的垃圾的定義與人行道垃圾的格式相同。街道垃圾趨勢與人行道垃圾相似。街道垃圾水平平均略低，這是有道理的，因為行人在人行道上花費更多時間，而且街道垃圾很可能是從車輛中掉落或從其他區域吹進來的。 2023 年 7 月至 2024 年 6 月期間，街頭垃圾平均為 2.40 件，低於上一期的 2.61 件。
全市範圍的傾銷情況沒有顯著變化
標準將傾倒定義為大於評估路線上垃圾的物品數量。全市範圍內，傾銷在資料收集期間保持相對穩定，2022 年1 月至12 月和2023 年1 月至6 月期間有所下降。件傾銷物品，大部分與2023 年1 月至2024 年6 月期間的水準沒有變化。
2022-2024 年全市傾倒垃圾的路線百分比
塗鴉在一段時間內波動，但隨著時間的推移保持穩定
塗鴉包括標記在建築物、人行道、街道人行道、樹木和其他公眾可見區域上的文字、符號和圖像。在城市街道或人行道上看到塗鴉的可能性仍然很高。 2023 年 7 月至 2024 年 6 月期間，86% 的評估路線有塗鴉，觀察到全市評估路線上平均有 18 處塗鴉。 2023 年 1 月至 6 月期間的平均值相同，略低於 2022 年 1 月至 12 月期間的 20 個。
2022-2024 年全市每條路線的平均塗鴉數量
2023年1月至6月至2023年7月至2024年6月糞便量增加
標準對評估路線上的糞便實例進行計數，並報告測量值，包括至少有一次糞便實例的路線百分比，以及糞便水平（路線上糞便實例的平均計數）。
2023年7月至2024年6月期間糞便水平仍然很高； 30% 的評估路線存在糞便。 2022年1月至2023年12月至2023年1月至6月，糞便數量有所減少，但2023年7月至2023年12月期間，觀察到的平均糞便數量急劇增加。 2024年6月，糞便水平變化顯著，但該期間全市平均仍高於前期。對於至少有一次糞便的路線百分比和平均糞便水平都是如此。

Neighborhood Findings
The following section details major trends across neighborhoods between July 2023-June 2024 and looks back at any changes over time. During this period of data collection, the number of evaluations increased and the sampling method changed to improve reliability of reporting at the neighborhood level (see Appendix 2 for more detail). For more detailed neighborhood maps visit the Street and Sidewalk Maintenance Standards dashboards.
Neighborhood trends between July 2023-June 2024
Between July 2023-June 2024 West of Twin Peaks and Noe Valley/Glen Park/Twin Peaks generally showed the least cleanliness issues while the Mission and the Tenderloin showed the most.

隨時間變化的社區趨勢
在大多數問題領域，社區層面的趨勢通常與全市範圍的趨勢相符。
2022年1月至2024年6月依社區劃分的存在糞便的路線百分比
- 在一些社區，至少有一次糞便的評估路線的百分比顯著增加，從2023 年1 月至2023 年6 月到2023 年7 月至2024 年6 月，在市場南部、卡斯特羅/上市場、波托拉/ Visitacion Valley 和 Bayview Hunters Point 社區。請注意，市場南部在前兩個時期的評估數量較少（評估了 18 條路線）。
- 維護標準定義了人行道間隙障礙物，其中人行道沒有至少四英尺寬和八英尺高的可通行空間。每當路線上至少有一個障礙區域時，都會進行評估。從2023 年1 月至2023 年6 月到2023 年7 月至2024 年6 月，每個社區的人行道清理問題平均減少了30 個百分點。人行道清理問題平均增加了21 個百分點） 2023 年 1 月至 2023 年 6 月。
Neighborhoods with a significant decrease in percent of routes with broken glass present, Jan 2022-Jun 2024
The percent of evaluated routes containing broken glass decreased in most neighborhoods, decreasing by 30 percentage points or more from January 2023-June 2023 to July 2023-June 2024 in the Castro/Upper Market, Hayes Valley/Haight Ashbury, and the Marina neighborhoods.
Dumping and graffiti trends varied the most from neighborhood to neighborhood.
- 大多數社區的傾倒量保持穩定，但與之前時期相比，一些社區的變化更大。 Oceanview/Merced/Ingleside & Lakeshore 地區包含傾銷的評估航線百分比增幅最高，從2023 年1 月至6 月期間的8% 增至2023 年7 月至2024 年6 月期間的31%。 Upper Market 的百分比下降幅度最大評估了含有傾銷的路線，從2023年1月至6月期間的47%增至2023年7月至2024年6月期間的27%。

其他發現
The following section contains more detailed findings on standards, including those addressed in the Key Findings section and on some additional standards like sidewalk clearance, broken glass, pavement condition, and other health hazards.
In some places there is context added from an additional small-scale study performed in 2024. The purpose and details of the study are below, and relevant findings are added in yellow boxes throughout this section.
Maintenance of Cleanliness Study
From January-June 2024, the Controller’s Office collaborated with Public Works to conduct the Maintenance of Cleanliness Study, an exploratory analysis of one of its street and sidewalk cleaning programs, CleanCorridorsSF, which focuses on deep, comprehensive cleaning of busy commercial corridors. This analysis focused on how long streets and sidewalks stay clean after cleaning, a resource concern for the department. The purpose of the study was to provide Public Works with focused data and analysis that could be useful for operations and internal decision-making, not a program evaluation.
Key analysis questions included:
- 深度清潔服務會在短期內影響街道和人行道的清潔度嗎？
- 清潔度的改善能持續多久？
為了解決這些問題，評估團隊分析了從不同社區的五個 CleanCorridorsSF 地點收集的數據。該研究在以下地點收集了清潔前一天、清潔後幾小時、清潔後第二天和清潔後一周的數據：
- 哥倫布 從 華盛頓 到 北灘的倫巴第
- 24日從巴倫西亞到Mission中的Potrero
- 海特 從 Divisadero 到 海特阿什伯里的拉古納
- 從 Noe 到 Guerrero 的第 16 路，以及從 Market 到 Upper Market 的 Church 和 Sanchez 的第 17 路
- 從日內瓦到埃克塞爾西奧的西克爾斯的任務
我們在報告的這一部分中將研究的初步結果放在黃色框中，其中它們為主要評估結果提供了有用的背景。
清潔度維護研究垃圾發現結果
這項小型研究的結果可能證明減少城市街道和人行道上的垃圾數量是困難的。
即使在不同社區進行了全面清潔工作後，結果也好壞參半：
除海特街外，清潔後大多數走廊的人行道垃圾都減少了。
即使一週後，Mission St 和 16th/Church/Sanchez 走廊的人行道垃圾也沒有恢復到最初的水平。
哥倫布大道走廊清潔後的第二天，街道垃圾就恢復到最初的等級。
24 街走廊清理一週後，街道垃圾也恢復到最初的階級。
Additional Litter Findings
Over half of evaluated routes between July 2023-June 2024 had only “a few traces” of litter.
Because we measure litter on routes on a five-point scale, providing only average levels doesn’t show the full range of resident experience.
Sidewalks with either very significant litter or zero litter might be very high salience for a resident but they are rare across the city. The percent of sidewalks with accumulated litter remained the same in the two most recent periods of data collection. Decreases in routes with more than a few traces of litter and increases in the level just below drove improvements in litter between July 2023-June 2024. As shown in the picture above, sidewalks rated between a two and a three might look something like this, with more than a few traces of litter, but no accumulation.
The image on the left shows litter level 2 "a few traces". The image on the right shows litter level 3 "more than a few traces". Note that the green color coding indicates sidewalk litter.
The graphic below shows the distribution of sidewalk litter and how it changed over the three data collection periods in 2022 and 2024.
Distribution of sidewalk litter levels citywide, 2022-2024
Graffiti
Graffiti levels on all property remained stable citywide.
In general, the City is responsible for removing graffiti from City property. Residents, business owners or building owners are responsible for graffiti on their properties, while other entities (such as BART or PG&E) are responsible for maintaining their properties. The standards separate graffiti on these three locations into separate measures, as well as capturing total graffiti across all property types.
Average counts of graffiti by property type per route evaluated citywide, 2022-2024
Average instances of graffiti observed on City property remained the same between July 2023-June 2024 after decreasing slightly between January-December 2022 and January-June 2023. Graffiti on the other two types of property remained the same across all three periods of evaluations.
清潔維護研究塗鴉結果
- 在所有評估的走廊中，城市擁有的財產上的塗鴉均有所減少（減少 18% - 49%）。
- 在評估的五個走廊中，有三個走廊的塗鴉數量甚至在一周後也沒有恢復到清潔前的數量。
- 私人財產上的塗鴉基本上沒有受到 CleanCorridors 清潔活動的影響，儘管大多數清潔的走廊都符合公共工程的塗鴉消除選擇加入計劃的資格。
- 清潔走廊清潔後的一天/一周內私人塗鴉的減少可能歸因於其他清潔工作，例如社區福利區清潔。
Percent of routes with at least one instance of offensive graffiti citywide, 2022-2024
The standards also define the presence of graffiti containing offensive language on a route. The proportion of routes with offensive graffiti was very low in the first two periods of data collection but spiked over the last year.
Dumping
Very large dumped items or grouped trash bags are rarely observed.
Because dumping is a major citywide and neighborhood concern and requires considerable resources both by the City and by Recology to remove, the standards were modified to capture more nuanced information. Removing larger items sometimes requires special equipment and teams from Public Works. To see how common it was for larger items to be dumped, the Controller’s Office included a question about the size of dumped items. It was rare for items larger than eight feet in diameter to be found on the street or sidewalk. Larger items appeared on about one percent of evaluated routes.
To better distinguish between trash bags that may have been intended for scheduled pick-ups and cleaning efforts and illegal dumping, we added a question to identify grouped trash bags. Evaluators observed these grouped bags on less than one percent of routes.
清潔度維護研究傾倒結果
在有大量傾倒垃圾的走廊（哥倫布大道和海特街），大型廢棄物在清潔後減少。
在海特街，大量的廢棄物數量花了一周時間才恢復到清潔前的數量。
在哥倫布大道上，即使一週後，大型廢棄物也沒有恢復到清潔前的數量。
Sidewalk Clearance
Sidewalk clearance issues increased over the first two periods of data collection and dropped rapidly and remained stable between July 2023-June 2024.
The standards define sidewalk clearance obstructions when the sidewalk is blocked either by temporary objects like a fallen tree branch or an improperly parked scooter or by permanent objects such as utility boxes. Sidewalk clearance is obstructed if it is reduced to less than four feet wide and eight feet tall at any point for any reason. Obstructions to the sidewalk can impede safe passage for pedestrians and people with disabilities.
Sidewalk clearance obstructions increased steadily over the 18 months between January 2022 and June 2023 before dropping sharply in the last period. The percent of routes with sidewalk clearance issues dropped by over 30 percentage points between January-June 2023 and July 2023-June 2024. Between July 2023-June 2024, 16 percent of sidewalks were obstructed.
Percent of routes with sidewalk clearance issues citywide, 2022-2024
These changes do not appear to be caused by seasonality. Since sidewalk clearance issues may be caused by items like downed branches or trees, we might expect clearance issues to be cyclical over a year, but we saw a steady increase for a year and a half and then a sharp drop. We did observe the highest rate of clearance issues during the winter and spring of 2023, which were marked by a series of severe winter storms with heavy rainfall and strong winds. Over that period, 21 percent of issues were identified as some type of tree, shrub, or other greenery, more than twice as high as during other times.
Top reasons for sidewalk clearance obstructions over time
Construction-related obstructions have been the most common reasons for sidewalk clearance issues across time periods. From January 2022 to June 2023, construction obstructions increased by 23 percentage points-rising from 21 percent of obstruction issues in January-December 2022 to 43 percent in January-June 2023. The rate of construction issues blocking sidewalks decreased by 34 percentage points, down to 10 percent between July 2023 and June 2024.
Trees, shrubs, or other greenery are the second most common obstruction issue. The percent of evaluated routes observed with greenery obstructions increased by 20 percentage points from January-December 2022 to January-June 2023, up from 18 percent to 37 percent. Between July 2023-June 2024, these obstructions decreased 34 percentage points and trees and other greenery comprised only three percent of sidewalk clearance issues citywide over that time period. This finding supports the trends noted above with the severe storms in the winter and spring of 2023.
Following trees, mobile objects like scooters, bicycles, and carts are the third most common reason for sidewalk clearance issues. Compared to construction and trees and other greenery, there is less variation in this category across time.
Broken Glass
The Street and Sidewalk Maintenance Standards define a five-point scale measuring the distribution of broken glass on a route. Measuring the distribution of glass helps distinguish areas with a high concentration, like a broken car window or bottle from a section of street or sidewalk with a small scattering of glass.
| Broken glass level | Glass description |
|---|---|
1 | None: the street and sidewalk are free of broken glass |
2 | A few traces: the street and sidewalk are predominantly free of broken glass except for a few small traces |
3 | More than a few traces but no concentration: there are no piles or lines of glass, and there are large gaps between pieces of glass |
4 | Glass is concentrated in a single line or spot: there may be small gaps between pieces of glass |
5 | Glass is concentrated in multiple lines or spots: if an area of broken glass is greater than 6 feet in diameter, consider it to be multiple spots |
- 2023 年 7 月至 2024 年 6 月期間，碎玻璃水準平均為 1.50，低於前兩個時期（2023 年 1 月至 6 月分別為 2.01，2022 年 1 月至 12 月為 1.89）。
- 超過一半的評估路線沒有碎玻璃，每個時期超過 70% 的玻璃分佈水平為「無」或「少量痕跡」。
- 2022 年 1 月至 2023 年 6 月期間，15% 至 20% 的評估路線存在一定程度的玻璃（可能是破碎的瓶子或車窗）。 2023 年 7 月至 2024 年 6 月期間，這一比例下降至 9%。
Glass distribution levels citywide, 2022-2024
Health Hazards
In addition to counting instances of feces, the standards define other health hazards, capturing a count of syringes, dead animals, and used condoms.
Syringes remain very rare across time periods. Less than one percent of routes had syringes in the first period of data collection and observations have decreased since. We observed syringes on 0.5 percent of routes between July 2023-June 2024.
Used condoms and dead animals are also extremely rare on observed routes.
Continuing high average feces levels are described in Key Findings. Challenges in lowering feces levels were observed in the Maintenance of Cleanliness Study as well.
保持糞便清潔度調查結果
即使在深度清潔之後，降低糞便水平仍然具有挑戰性：
清潔走廊五個地點中的四個地點在清潔後，糞便水平基本上保持不變。
只有使命街走廊的糞便在清潔後直接減少，並很快恢復到原來的水平。
在海特街和第 16 街/教堂/桑切斯走廊，糞便在清潔當天仍然很高，並在第二天有所減少，這可能與 CleanCorridors 的清潔無關。
清潔工作可能對糞便水平沒有影響，或者糞便水平的增加發生得太快，無法在清潔當天下午的評估中捕捉到。
Pavement Condition
More than two thirds of routes citywide have some pavement defect in every period.
The pavement condition of the City’s sidewalks is important for ease of passage as well as the City’s broader infrastructure. Standards define sidewalk defects as missing or sunken pavement or cracks, chips, and voids, and include both those marked for repair and those not yet marked. Evaluators rate the severity of defects at each route in three categories-minor, moderate, and severe.
| Defect level | Pavement defect description |
|---|---|
1 | Minor: Cracks, chips, and voids up to one inch and no raised/sunken/uneven pavement with a vertical displacement greater than 0.5 inches. |
2 | Moderate: Cracks, chips, and voids larger than 1 inch exist but they are generally isolated and no raised/sunken/uneven pavement with a vertical displacement greater than one inch. |
3 | Severe: Large areas of missing or deteriorated pavement with widespread spalling. Raised/sunken/uneven pavement exists with a vertical displacement greater than one inch. |
2022 年至 2024 年，全市範圍內存在人行道路面缺陷的評估路線的百分比
每個時期都有超過一半的評估路線出現中度至重度路面缺陷，但在2023 年7 月至2024 年6 月期間，沒有任何路面問題的評估路線的百分比有所增加。嚴重路面缺陷水準有所波動，但維持較為穩定中度缺陷在 2023 年 1 月至 6 月期間激增。
2022-2024 年全市人行道路面缺陷水平
垃圾桶
我們測量路線上溢出的垃圾容器，包括城市垃圾桶和私人維護的容器，例如有時由社區福利區管理的容器。 2023 年 7 月至 2024 年 6 月期間，23% 的評估路線至少設有一個垃圾箱。
- 垃圾桶溢出的情況在各個時期都很罕見——佔所有評估路線的 0.8% 到 2%。
- 到 2022 年，在設有垃圾箱的路線中，有 9% 的垃圾箱溢出。
過境避難所
當評估路線上有過境候車亭時，我們經常觀察到清潔問題。過境避難所通常由 SFMTA 而不是公共工程部門維護。
- 每個時期，有公車候車亭的路線中清潔問題的百分比都超過 80%。 2023年7月至2024年6月期間略為下降至83%，低於前兩個時期的87%和89%。
- 在交通庇護所觀察到的最常見的清潔問題是糞便、塗鴉以及停放不當的踏板車或自行車。
將標準與 311 居民服務請求進行比較
311 服務請求
311 客戶服務中心為紐約市居民的各種非緊急請求提供支援－從街道和人行道清潔到停車執法。服務請求可作為公共資料集提供。由於數據集的規模和可用性，它們經常被公眾用於研究或報告，並被城市用於營運或決策。然而，由於 311 數據完全基於居民和訪客報告，如果某些社區的人們或多或少可能報告，或者總是報告特定問題而其他問題則不報告，則數據可能會出現偏差。
| 311 service request categories | Standards categories |
|---|---|
Street and sidewalk cleaning requests (excluding dumping and human or animal waste) | Street and sidewalk litter |
Dumping | Dumping |
Graffiti | Graffiti |
Human or animal waste | Feces |
Blocked street or sidewalk | Sidewalk obstruction |
Several service request categories in 311 mirror issues in the Street and Sidewalk Maintenance Standards, as shown in the table here (see Appendix 6 for more detail). Although the 311 service request categories do not map exactly to the street and sidewalk standards, they are closely related and provide insight into whether and how San Francisco resident and visitor reports differ from the Controller’s Office’s randomly selected observational data.
We examine relevant 311 service request trends over the same timeframe as standards evaluations to compare trends over time at a citywide level and across neighborhoods. For each 311 service request category we calculate an average monthly number of requests per mile of street to compare neighborhoods of different sizes.
The graph below shows the monthly average total 311 requests related to street and sidewalk issues for each standards evaluation time period. The table shows the overall totals for these 311 requests. Monthly requests increased between January-June 2023 before decreasing slightly between July 2023-June 2024.
311 requests for street and sidewalk related issues, monthly average totals citywide, 2022-2024
| Time period | 311 Street & sidewalk issue request totals |
|---|---|
January-December 2022 | 384,863 |
January-June 2023 | 240,994 |
July 2023-June 2024 | 449,629 |
311 Requests match some but not all standards trends
Cleaning requests make up a large and increasing proportion of all street and sidewalk related requests. After street and sidewalk cleaning, dumping and graffiti requests are the next largest categories.
To visualize these changes across service categories, we created an index value, setting January-December 2022 equal to 100, and using the monthly average values to observe changes in the later two time periods. In the visual below, we can see this increase in street and sidewalk cleaning requests, while requests for feces and dumping changed very little over time.
Proportion of cleaning requests by service category and standards time period
| 311 Request category | January-December 2022 | January-June 2023 | July 2023-June 2024 |
Street & sidewalk cleaning | 39% | 50% | 52% |
Dumping | 28% | 21% | 20% |
Graffiti | 20% | 20% | 18% |
Feces | 9% | 7% | 8% |
Index change values in average monthly 311 street and sidewalk condition service requests citywide: Street and sidewalk cleaning, Graffiti, Feces, Dumping, 2022-2024
Street and sidewalk cleaning requests have been increasing since 2022 while observed litter levels decreased slightly.
Among the four service categories we focus on, we see the largest difference between 311 requests and citywide standards findings for street and sidewalk cleaning. Although litter levels have remained relatively stable year over year in the standards evaluations, monthly average requests for street and sidewalk cleaning increased by 59 percent from the first to second period, and decreased by less than three percent between July 2023-June 2024. Comparing the litter levels from standards evaluations, we see a slight decrease that looks quite different from the steeper, upward trend in requests.
Index change values in 311 street and sidewalk cleaning requests, and citywide standards averages for sidewalk litter and street litter, 2022-2024
The steady downward trend in requests related to large, dumped items tracks with stable trends in standards evaluations.
Monthly average requests for large, dumped items decreased consistently over time. Monthly average dumping requests decreased at the same rate of eight percent between January-December 2022 to January-June 2023, and then from January-June 2023 to between July 2023-June 2024. Dumping in street and sidewalk standards evaluations has shown a similar, stable to slightly decreasing trend over time.
Index change values in 311 dumping requests and citywide standards averages for dumping, 2022-2024
Graffiti requests reflect more variance in contrast to the stable trends in graffiti over time.
311 service requests related to graffiti are more variable over time. They increased by 23 percent from January-December 2022 to January-June 2023, and decreased by 18 percent in 2024. In contrast, in the standards evaluations average instances of graffiti decreased from January-December 2022 to January-June 2023 by 12 percent and remained relatively unchanged after that.
Index change values in 311 graffiti requests and citywide standards averages for graffiti, 2022-2024
Feces-related requests are unchanged despite rising observed human or animal waste in standards.
Service requests related to human or animal waste are much more stable over time than the frequency observed in standards evaluations.
Index change values in 311 feces requests and citywide standards averages for feces, 2022-2024
Neighborhood findings in service requests
The following section compares trends in 311 service requests across neighborhoods to trends observed in standards evaluations between July 2023-June 2024. We use average monthly number of requests per mile of street to identify neighborhoods with high or low volumes of requests to see if relative patterns are similar to those in standards evaluations. For more detailed 311 neighborhood maps visit the 311 Service Requests by Neighborhood dashboards.
The maps below show relative severity across the city and the tables list the five neighborhoods with the most 311 requests and highest observed severity from the standards.
- The Tenderloin and the Mission both appear in the top five neighborhoods for severity in all issue areas, and in both 311 requests and standards evaluations.
- Other neighborhoods appear much more frequently in 311 requests than the evaluated severity of issues would predict. The grouped neighborhood of Russian Hill, Nob Hill, and North Beach appears in three of four issue areas despite low-to-average evaluated litter levels, dumping, graffiti, and feces.
- Other neighborhoods like Chinatown, Hayes Valley and Haight Ashbury, and South of Market show up relatively frequently in one or both of the measures, suggesting that they are not perfectly aligned on all issues, but there aren’t large differences in patterns between service requests and evaluated standards.
Street and sidewalk cleaning
Average monthly 311 street and sidewalk cleaning requests per mile by neighborhood, Jul 2023-Jun 2024. Note that the five neighborhoods with the highest average 311 cleaning requests are labeled here.
Average sidewalk litter level by neighborhood, Jul 2023-Jun 2024. Note that the five neighborhoods with the highest average standards evaluations are labeled here.
Two out of five neighborhoods with the highest litter levels in standards evaluations, align with neighborhoods with higher monthly average requests for this issue: the Tenderloin and the Mission.
Comparing monthly average 311 cleaning requests to average sidewalk litter levels shows that some neighborhoods with some of the most severe litter issues, like the Bayview and South of Market, are not necessarily the same as neighborhoods reporting cleanliness issues.
These 311 requests align with neighborhood-level standards evaluation findings for the Tenderloin and the Mission, which had higher street and sidewalk litter levels. However, Chinatown had relatively lower litter levels between July 2023-June 2024, closer to a value of two (a few traces of litter), suggesting residents there submit more 311 requests at a given litter level than in other neighborhoods.
