Figure 3-3: 1/2 Mile Parkshed with Existing Residential Use

For each neighborhood park, community park, community center, special use park, and regional park, a GIS analysis was completed that generated polygons representing a 15-minute walkshed, given a walking speed of 2.5 mph (slowed to 2 mph to take into account street crossings, some with signals). The 5-minute driveshed assumed posted speed limits which tends to average 35 mph with it slowing to 30 mph average with signals and parking at each end of the trip. Resulting walkshed polygons were superimposed on the city base map to see which regions were well covered by park access and to estimate the number of residents served by park type.

Forty-four percent of residents are served by the 15-minute walkshed for the neighborhood parks, highlighting the need for additional neighborhood parks, especially north-east and east Montebello. The 5-minute bike/driveshed serves 51 percent of the community for parks, community centers, special use parks, and regional parks.

3.6.1 PARKSHEDS

There are three different parksheds used to analyze the service area a park provides to the City: walkshed, bikeshed, and driveshed. For each park type, a Geographical Information System (GIS) analysis generated a polygon representing a 15-minute walkshed (given a walking speed of 2.5 mph, slowed to 2 mph for signalized intersections) and a 5-minute driveshed (includes total travel time with approximate delay due to traffic signals and finding parking). The resulting service catchment areas were overlaid on the city base map to see which regions were well covered by park access and to estimate the number of residents served by park type. Table 3-7 is a summary of the parkshed assumptions. Populations within a 15-minute walkshed are typically covered by mini parks and neighborhood parks, whereas, populations within a 5-minute driveshed are served by community parks/ centers and regional parks. Figure 3-4 displays a halfmile parkshed (typical walkshed) and residential density in Montebello to show which areas of Montebello have convenient access to parks.
