The purpose of this handout is to provide in advance of the October 8th Technical Peer Review (TPR) meeting an update on the well-to-parcel map, 2005 and 2018 land use maps, and a table summarizing the assumed status (i.e., active versus inactive) of groundwater pumping wells during the historical simulation period and at present. The information provided herein has been prepared by Jacobs Engineering Group, Inc. (Jacobs) on behalf of the San Pasqual Valley (SPV) Groundwater Sustainability Agency (GSA). Jacobs is using this information to help develop a numerical integrated flow model that will support development of the SPV Groundwater Sustainability Plan (GSP).

Well-to-parcel Map

Well-to-parcel associations are needed to develop the numerical integrated flow model (GSP Model). This model will be used to compute historical, current, and future water budgets per GSP Regulations. The attached well-to-parcel map was developed based on the following data sources:

Feedback from SPV GSA representatives, TPR members, and selected stakeholders

San Pasqual Valley Groundwater Basin Salt and Nutrient Management Plan (SNMP) (CH2M HILL 2014) mapping effort completed in conjunction with City of San Diego staff

2018 City of San Diego Wells & City Leases Map and Domestic 2016 Water Supply Schematic

City of San Diego master well database and Rancho Guejito wells GIS layer

San Diego County well completion reports

Of the information sources listed above, Jacobs mostly relied upon information provided by SPV GSA representatives and information acquired and used during the development of the SNMP. The accuracy of the map has been improved upon by incorporating thoughtful review comments received from the entities listed above.

Land Use Maps

Land use mapping is also needed as part of GSP Model and GSP development. Jacobs has developed 2005 and 2018 land use maps with the aid of the following data sources:

Feedback from SPV GSA representatives, TPR members, and selected stakeholders

SanDAG/SanGIS land use data

Comments received from Rancho Guejito on the SanDAG land use data

1998 San Diego County land use survey performed by CA DWR

2014 and 2016 Land IQ land use classifications provided by CA DWR

SNMP (CH2M HILL 2014) land use classifications and Google Earth™ historical aerial imagery

Of the information sources listed above, Jacobs mostly relied upon 2018 aerial imagery, land use mapping developed for the City of San Diego during preparation of the SNMP, and recent information provided by SPV GSA representatives. The accuracy of the map has been improved upon by incorporating thoughtful review comments received from the entities listed above.

Pumping Well Status through Time

The well-to-parcel and land use maps help establish important associations among parcels, irrigated lands, and pumping wells represented in the GSP Model. However, just as important as the spatial distribution of this information is the temporal distribution of groundwater pumping during the 15-year historical simulation period, including water year (WY) 2005 through WY 2019. The status of each modeled pumping well through time was developed based on information gained from the well-to-parcel map development and from City of San Diego staff input. A summary table of the modeled pumping well status through time is provided below. The accuracy of this information has been improved by incorporating thoughtful review comments received from SPV GSA representatives.
