Initial Study/Proposed Negative Declaration for Land Acquisition for a Future Employee Parking Lot/Corporation Yard Extension

Project Overview:

The intended purpose of the land acquisition is to expand the Soquel Creek Water District’s parking and corporation yard capacity by eventually constructing an internally accessed parking area that will be available for employee parking, fleet vehicles and equipment storage.

The opportunity to purchase the land is underpinned by the Soquel Creek Water District Draft Master Plan Report, by Noll & Tam Architects, released in March of 2015. The report identified the District’s current needs, vision, and objectives for its existing 5180 Soquel Drive headquarters. One of the key objectives detailed within the Master Plan is the District’s need for the acquisition of an adjacent vacant lot located directly west of the existing facility.

Soquel Creek Water District is the Lead Agency for the project. The property purchase is intended to be completed after the environmental review is certified.

Mapping saltwater intrusion with an airborne electromagnetic method in the offshore coastal environment, Monterey Bay, California

Three-hundred and twenty line-kilometers of airborne electromagnetic (AEM) data were acquired offshore. These data spanned 20 km of coastline, extending up to 3.5 km offshore in water up to 18 m in depth. Inversion of these data resulted in resistivity models extending to depths between 50 and 200 m below sea level. The data were interpreted in conjunction with onshore monitoring well data, hydrologic and geologic reports, and electrical resistivity tomography (ERT) data to locate the freshwater/saltwater interfaces throughout the region. A resistivity-to-water-quality transform was established using well-based water quality and resistivity logging measurements. For resistivity values that could not be converted to water quality with this transform, local auxiliary information was used on a case-by-case basis to interpret the observed features. Some low resistivity anomalies were identified near the shore at depth, which were interpreted to be artifacts of the 1D assumption in the inversion scheme used for these AEM data.

We found that the acquisition of AEM data provided valuable information about water quality in the offshore extents of the aquifers, a region inaccessible to traditional monitoring methods, but one that plays an important role in the modeling, prediction, and management of saltwater intrusion.

Potential Injection Aquifer Geochemical Characterization

Injection of purified water into a groundwater aquifer can lead to geochemical reactions such as mineral dissolution, oxidation, or desorption.   The potential for oxidation or mineral dissolution to occur can be mitigated through purified water post-treatment stabilization prior to injection.  Geochemical characterization of potential aquifer soils in the injection area can provide the data needed for geochemical modeling and to design an effective water purification process. The geochemical characterization work summarized herein includes conducting soil leaching analysis under “worst-case” scenario conditions to establish a baseline if post-treatment stabilization was not carried out on the purified water. Understanding the baseline, worst-case scenario can aid in establishing and optimizing the post-treatment stabilization regime for the target groundwater aquifer. [This is a large file, 99MB]
