EXECUTIVE SUMMARY
The Napa County Groundwater Sustainability Agency (NCGSA) intends to install a dual-completion monitoring well on a County-owned parcel (APN 009-392-045-000) located adjacent to the Saint Helena Public Cemetery in the City of St. Helena. The City of St. Helena has agreed to share in the cost of installation of dual-completion wells installed on said parcel by providing $30,000 in funding with the details of the arrangement described in the Memorandum of Understanding and Cost Share Agreement No. 240144B. The NCGSA portion of costs will be paid from existing Prop 68 grant that the NCGSA was awarded from the California Department of Water Resources. Access to the County-owned parcel for purposes of installing and maintaining the well is only possible by entering through the Cemetery, necessitating a Right of Way Easement Deed with the owner, the Saint Helena Public Cemetery Association which is the subject of a separate item presented to the Board of Supervisors.

BACKGROUND AND DISCUSSION
The NCGSA regularly monitors a network of public, private and County-owned wells that currently number 114 current, active wells, of which eight (8) are new, dedicated monitoring wells installed between January and May 2023 using Prop 68 grant funds from the Department of Water Resources. The eight (8) new wells were installed at four (4) sites throughout the Napa Valley Subbasin and are designed to further understanding of the groundwater and surface water interactions at in those locations which are adjacent to Ritchey Creek, Soda Creek and the Napa River.
Following the installation of the eight (8) new wells in spring 2023, there remain some unspent Prop 68 funds which the NCGSA intends to use to install additional dedicated, dual-completion monitoring wells. The NCGSA has identified four (4) suitable locations:
1. Conn Creek at Oakville Cross Road (in County Right of Way)
2. Napa River at Deer Park Road (in County Right of Way)
3. Redwood Road near the intersection of Dry Creek Road (in City of Napa Right of Way)
4. County-owned parcel located along Sulphur Creek adjacent to the Saint Helena Public Cemetery
The City of St. Helena has agreed to share in the cost of well installation at the fourth location listed above. The cost to install dual-completion wells at this site is estimated at $40,573 and City of St. Helena has agreed to reimburse the NCGSA a total of $30,000 as described in NCGSA Agreement No. 240144D. The remaining costs for the installation of the monitoring well will be paid for using an existing Prop 68 grant that the NCGSA was awarded from the California Department of Water Resources.
The first two locations require encroachment permits issued by Napa County Roads Department. The third location requires an encroachment permit and license agreement with City of Napa which will be the subject of a future NCGSA item. Access to the County-owned parcel for purposes of installing and maintaining the well is only possible by entering through the Saint Helena Public Cemetery, necessitating a Right of Way Easement Deed with the owner, the Saint Helena Public Cemetery Association, which is the subject of a separate item presented to the Board of Supervisors. If this item is approved, the NCGSA expects to install a dual-completion monitoring well on the County-owned parcel identified herein no later than October 30, 2023.
