- Puerto Rico Potential Access to Parks (Southeast Blueprint Indicator) [United States]
- Description
- Reason for Selection Protected natural areas help foster a conservation ethic by providing opportunities for people to connect with nature, and also support ecosystem services like offsetting heat island effects (Greene and Millward 2017, Simpson 1998), water filtration, stormwater retention, and more (Hoover and Hopton 2019). In addition, parks, greenspace, and greenways can help improve physical and psychological health in communities (Gies 2006). Parks contribute to Puerto Rico's natural infrastructure and help increase resiliency to high-intensity storms and flooding. For example, urban forests can support soil stabilization, improve air and water quality, reduce urban heat effects, and improve stormwater management (Resetar et al. 2020). Similarly, parks along Puerto Rico's coastline that support coral reefs, seagrasses, and marine wetlands can help reduce storm energy and protect the coastline from flooding and erosion (Guannel et al. 2016). Parks also help connect Puerto Rico's local population and tourists to natural and cultural resources. Every Puerto Rican municipality has local and commonwealth parks that are significant to local residents and help support local tourism. Parks that are nearby and walkable to communities also offer recreation benefits and opportunities to connect with wildlife, in addition to localized ecosystem services. However, parks are not equitably distributed within easy walking distance for everyone, especially outside of major municipalities like San Juan. This indicator prioritizes places where new parks can help to serve communities that lack nearby park access. It also complements the urban park size indicator by capturing the value of potential new parks. Input Data The Trust for Public Land (TPL) ParkServe database , accessed 31-12-2024: Park priority areas (ParkServe_ParkPriorityAreas, ParkServe_10MWServiceAreas, ParkServe_Parks) From the TPL ParkServe documentation : The ParkServe database maintains an inventory of parks for every urban area in the U.S., including Puerto Rico. This includes all incorporated and Census-designated places that lie within any of the country's 3,000+ census-designated urban areas . All populated areas in a city that fall outside of a 10-minute walk service area are assigned a level of park priority, based on a comprehensive index of six equally weighted demographic and environmental metrics: Population density Density of low-income households - which are defined as households with income less than 75 percent of the urban area median household income Density of people of color Community health - a combined index based on the rate of poor mental health and low physical activity from the 2020 CDC PLACES census tract dataset Urban heat islands - surface temperature at least 1.25o greater than city mean surface temperature from The Trust for Public Land, based on Landsat 8 satellite imagery Pollution burden - Air toxics respiratory hazard index from 2020 EPA EJScreen The 10-minute walk For each park, we create a 10-minute walkable service area using a nationwide walkable road network dataset provided by Esri. The analysis identifies physical barriers such as highways, train tracks, and rivers without bridges and chooses routes without barriers. Centers for Disease Control (CDC) Social Vulnerability Index 2022 (Puerto Rico): RPL_Themes Social vulnerability refers to the capacity for a person or group to "anticipate, cope with, resist and recover from the impact" of a natural or anthropogenic disaster such as extreme weather events, oil spills, earthquakes, and fires. Socially vulnerable populations are more likely to be disproportionately affected by emergencies (Wolkin et al. 2015). In this indicator, we use the "RPL_THEMES" attribute from the Social Vulnerability Index, described here. "The Geospatial Research, Analysis, and Services Program (GRASP) at Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry developed the Social Vulnerability Index (SVI). The SVI is a dataset intended to help state, local, and tribal disaster management officials identify where the most socially vulnerable populations occur (Agency for Toxic Substances and Disease Registry [ATSDR] 2018)" (Flanagan et al. 2018). "The SVI database is regularly updated and includes 15 census variables (ATSDR 2018). Each census variable was ranked from highest to lowest vulnerability across all census tracts in the nation with a nonzero population. A percentile rank was calculated for each census tract for each variable. The variables were then grouped among four themes.... A tract-level percentile rank was also calculated for each of the four themes. Finally, an overall percentile rank for each tract as the sum of all variable rankings was calculated. This process of percentile ranking was then repeated for the individual states" (Flanagan et al. 2018). Southeast Blueprint 2025 extent Mapping Steps From the Puerto Rico ParkServe data, remove the 10-minute walk service areas and current parks from the park priority areas. This removes areas that are already being served by an existing park, which are not the focus of this indicator.. Convert the resulting layer to raster using the ParkRank field. Note: The ParkRank scores are calculated using metrics classified relative to each city. Each city contains park rank values that range from 1-3. For the purposes of this indicator, we chose to target potential park areas to improve equity. Because the ParkRank scores are relative for each city, a high score in one city is not necessarily comparable to a high score from another city. In an effort to try to bring more equity into this indicator, we also use the CDC Social Vulnerability Index to narrow down the results. Reclassify the ParkServe raster to make NoData values 0. Convert the SVI layer from vector to raster based on the "RPL_Themes" field. In the source geodatabase, the field name is "RPL_Themes" and the alias for that field is "Overall percentile ranking" To limit the ParkRank layer to areas with high SVI scores, first identify census tracts with an "RPL_Themes" field value >0.65. Make a new raster that assigns a value of 1 to census tracts that score >0.65, and a value of 0 to everything else. Take the resulting raster times the ParkRank layer. Reclassify this raster into the 4 classes seen in the final indicator below. As a final step, clip to the spatial extent of Southeast Blueprint 2025. Note: For more details on the mapping steps, code used to create this layer is available in the Southeast Blueprint 2025 Data Download or Caribbean-only Southeast Blueprint 2025 Data Download under > 6_Code. Final indicator values Indicator values are assigned as follows: 3 = Very high priority for a new park to serve people who lack nearby park access 2 = High priority for a new park to serve people who lack nearby park access 1 = Moderate priority for a new park to serve people who lack nearby park access 0 = Not identified as a priority for a new park to serve people who lack nearby park access (within urban areas) Known Issues The ParkServe database has many missing and incomplete parks in Puerto Rico (e.g., Cabo Rojo National Wildlife Refuge, parts of Balneario Seven Seas in Fajardo). As a result, it overestimates park need in the surrounding areas. TPL regularly updates ParkServe to incorporate the best available park data. We encourage users to report missing parks or errors in the park boundaries or attributes. You can submit corrections through the ParkReviewer tool or by contacting TPL staff . Within a given area of high park need, the number of people served by the creation of a new park depends on its size and how centrally located it is. This indicator does not account for this variability. Similarly, while creating a new park just outside an area of high park need would create access for some people on the edge, the indicator does not capture the benefits of new parks immediately adjacent to high-need areas. For a more granular analysis of new park benefits, ParkServe's ParkEvaluator tool allows you to draw a new park, view its resulting 10-minute walk service area, and calculate who would benefit. Beyond considering distance to a park and whether it is open to the public, this indicator does not account for other factors that might limit park access, such as park amenities or public safety. The TPL analysis excludes private or exclusive parks that restrict access to only certain individuals (e.g., parks in gated communities, fee-based sites). The TPL data includes a wide variety of parks, trails, and open space as long as there is no barrier to entry for any portion of the population. The indicator does not incorporate inequities in access to larger versus smaller parks. In predicting where new parks would benefit nearby people who currently lack access, this indicator treats all existing parks equally. This indicator identifies areas where parks are needed but does not consider whether a site is available to become a park. We included areas of low intensity development in order to capture vacant lots, which can serve as new park opportunities. However, as a result, this indicator also captures some areas that are already used for another purpose (e.g., houses, cemeteries, and businesses) and are unlikely to become parks. In future updates, we would like to use spatial data depicting vacant lots to identify more feasible park opportunities. This indicator underestimates places in rural areas where many people within a socially vulnerable census tract would benefit from a new park. ParkServe covers incorporated and census-designated places within census-designated urban areas, which leaves out many rural areas. We acknowledge that there are still highly socially vulnerable communities in rural areas that would benefit from the development of new parks. However, based on the source data, we were not able to capture those places in this version of the indicator. Some high-scoring areas may have access to nearby greenways and trails that can serve many of the roles of parks. This indicator does not account for access to nearby greenways and trails. Other Things to Keep in Mind The zero values in this indicator contain three distinct types of areas that we were unable to distinguish between in the legend: 1) Areas that are not in a community analyzed by ParkServe (ParkServe covers incorporated and census-designated places within census-designated urban areas); 2) Areas in a community analyzed by ParkServe that were not identified as a priority; 3) Areas that ParkServe identifies as a priority but do not meet the SVI threshold used to represent areas in most need of improved equitable access. This indicator only includes park priority areas that fall within the 65 th percentile or above from the Social Vulnerability Index. We did not perform outreach to community leaders or community-led organizations for feedback on this threshold. This indicator is intended to generally help identify potential parks that can increase equitable access but should not be solely used to inform the creation of new parks. As the social equity component relies on information summarized by census tract, it should only be used in conjunction with local knowledge and in discussion with local communities (NRPA 2021, Manuel-Navarete et al. 2004).
