Urbanization within the Study Area has increased through time (see Figure 7). Native vegetation
has always covered the greatest portion of the Study Area. In 1974, high-density residential
covered the greatest non-native vegetation area although areas occupied by irrigated agriculture,
commercial land use, and low-density residential were proportionally similar. Since 1974, areas
of irrigated agriculture have decreased significantly while areas of high density residential and
urban landscape have increased significantly. Areas of urban commercial and low-density
residential have remained relatively constant over time. Total urbanization across the Study
Area has increased from approximately 4,000 acres in 1974 to approximately 10,000 acres in
2010 (see Figure 8).

2.4 Groundwater Production Wells and Recharge Facilities

2.4.1 Groundwater Production Wells
Groundwater pumping in the Study Area occurs via production wells operated by the various
water districts, local mutual water companies, and private well owners (see Figure 9). There are
more than 100 production wells in the Study Area with pumping records since 1927 (see
Appendix A). Of these wells, there are currently 27 active Overlyer wells and 19 active
Appropriator wells.

2.4.2 Groundwater Recharge Facilities

Two large-scale artificial recharge facilities are located within the Study Area: the Little San
Gorgonio Creek Recharge Facility (LSGCRF) and the Noble Creek Recharge Facility (NCRF).
Both facilities are located on BCVWD property. The LSGCRF is located north of Orchard
Street on the northwest side of Avenue Miravilla (see Figure 9). The SGPWA began recharging
imported State Project water at this facility in 2004. It is noted that the LSGCRF is located
immediately outside the Beaumont Basin. The NCRF is located northeast of the corner of
Beaumont Avenue and Brookside Avenue within the Beaumont Basin. The BCVWD began
recharging imported State Project water at this facility in 2006. To date, only imported water has
been delivered to both artificial recharge facilities.

In addition to the large-scale artificial recharge facilities, three storm water capture basins have
recently been built within the City of Beaumont (see Figure 9). To date, no data is available
regarding flows into and out of these basins.
