A household survey in Southern California to estimate current outdoor water use habits, environmental attitudes, and penetration rates of different landscaping types.

This project is a CaDC collaborative project between CivicSpark, and participating utilities including the Santa Ana Watershed Project Authority (SAWPA), the Inland Empire Utilities Agency (IEUA) and the Eastern Municipal Water District (EMWD).

• Steven Kerns
• Ana Patricia Lopez
• Abbey Pizel
• Amanda Schallert

• Patrick Atwater
• Christopher Tull

Code to generate the survey sample is located in the notebooks/create_sample file.

• Santa Ana Watershed boundary polygon
• California census block group polygons
• California parcel boundaries

All shapefiles have been reprojected to EPSG 3310 using a process like the following in PostGIS:

--After loading shapefile, set the current column projection
SELECT UpdateGeometrySRID('census_blockgroup_polygons_2016', 'geom', 4269);

ALTER TABLE census_blockgroup_polygons_2016 ADD COLUMN geom_3310 geometry(MultiPolygon,3310);

UPDATE census_blockgroup_polygons_2016 SET geom_3310 = ST_Transform(geom, 3310)
WHERE ST_SRID(geom) = 4269;
