  • Irrigated Lands Regulatory Programs Coalition Approach to Salinity Related Exceedances
    Irrigated Lands Regulatory Programs Coalition approach to Salinity Related Exceedances The Irrigated Lands Regulatory Program (ILRP) agriculture water quality coalitions are actively engaged in the Central Valley Salinity Alternatives for Long term Sustainability (CVSALTS) process and a number are members of the Central Valley Salinity Coalition. In addition to the CVSALTS effort, coalitions whose members discharge to the San Joaquin River are working to implement the San Joaquin River at Vernalis Salinity and Boron Total Maximum Daily Loads (TMDLs). The Irrigated Lands Regulatory Program requires a coalition to prepare a management plan, if a water quality trigger is exceeded more than once in a three year period. The management plan must include the following elements: 1) identification of agricultural source; 2) identification of management practices to be implemented; 3) schedule for implementation of management practices; 4) management practice performance goals; 5) monitoring schedule; 6) process for evaluating management practice effectiveness; 7) identification of participants who will implement the plan; and 8) a schedule for reporting to the Central Valley Water Board. The Coalitions with salinity issues are generally relying on their participation in the CV- SALTS effort to address those management plan elements. A brief overview of the general approach used by ILRP Coalitions addressing salinity issues is provided below. WESTSIDE SAN JOAQUIN RIVER WATERSHED COALITION The Westside Coalitions primary goals/ activities associated with salinity are: • Identify sources of salinity within the Westside Coalition and variations in different areas. • Incorporate appropriate activities to address salinity as they are identified and required by the Central Valley Water Board. • Participate in ongoing Central Valley Water Board programs for the management of salinity • Conduct monitoring to track changes in TDS, EC, and boron to evaluate the impact of the strategy.

BOX 121 SANTA CLARA, CALIFORNIA 95052 J2015-011.01 EXECUTIVE SUMMARY Santa Clara University (SCU) is proposing its 2020 Plan for the enhancement of the University’s education programs and student support. Santa Clara 2020 is an integrated strategic five-year development plan that incorporates overall University goals in education with an Enrollment Plan and Facilities Master Plan. Santa Clara University is planning to create districts of like disciplines on campus, thus enhancing the opportunities for students and staff to work across closely allied fields. The University is also continuing its program of modernizing or replacing facilities. A significant part of Santa Clara 2020 is the University’s five-year program of capital improvement projects. The major capital projects comprise the Unified Facility for the School of Law, the STEM (Science, Technology, Engineering, and Mathematics) Center, and two new residence halls. Other projects include replacement of the Cowell Center; additions to the Pat Malley Fitness Center, Benson Center, and Dunne Hall; and demolition of Kennedy Commons and the Daly Science Center.

The recommendations are based on data and information collected from the Central Valley Regional Water Quality Control Board (Central Valley Water Board) surface waterbodies (rivers, lakes, and delta) and submitted prior to the end of the data solicitation period for the 2018 Integrated Report cycle. Proposed revisions to the 303(d) list during the 2018 Integrated Report cycle were limited to impaired waterbodies addressed by existing regulatory programs. A full assessment of all readily available data for Central Valley Water Board surface waters will be completed during the 2020 integrated reporting cycle. This staff report provides background on the assessment process and the methods used. Primary data sources include several coalitions enrolled in the Central Valley Water Board’s Irrigated Lands Regulatory Program, the Surface Water Ambient Monitoring Program, and the California Department of Pesticide Regulation.

  • Stanislaus Multi-Agency Regional Storm Water Resource Plan
    STANISLAUS COUNTY DEPARTMENT OF PUBLIC WORKS Stanislaus Multi-Agency Regional Storm Water Resource Plan Section 2. Planning Area Description Prepared for: State Water Resources Control Board Grant Agreement No. D1612618 Submitted by: Stanislaus County, Department of Public Works November 2017 Prepared by: Stanislaus Multi-Agency Regional Storm Water Resource Plan Section 2 Planning Area Grant Agreement No. D1612618 Description Final Section 2. Planning Area Description Stanislaus County encompasses 1,515 square miles in California’s Central Valley, with its western border in the Coast Range, southwest of the San Francisco Bay. The County extends to the Sierra Nevada foothills in the east (Figure 1). According to 2016 census estimates, Stanislaus County has a population of 541,560. The western portion of the County is mostly undeveloped rangeland. Outside of this area, agricultural land and rangeland constitute a major fraction of the County (45% and 36% respectively), with urban land of varying density constituting 13% of the area. The Stanislaus Multi-Agency Regional SWRP (SWRP) planning area aligns with the Stanislaus County boundaries and includes the bulk of two major watersheds, the Middle San Joaquin-Lower Merced-Lower Stanislaus and the Panoche-San Luis Reservoir watersheds. This planning area was chosen to facilitate regional planning and evaluation based on significant overlap with the East Stanislaus and Westside San Joaquin Integrated Regional Water Management Plan (IRWMP) areas, as well as the Stanislaus and Tuolumne Rivers Groundwater Basin Association (STRGBA), Turlock Groundwater Basin Association (TGBA), and San Luis & Delta-Mendota Water Authority (SLDMWA) groundwater management planning areas. The SWRP planning area is entirely within the San Joaquin River Hydrologic Region.
