Study Description. The goal of the study is to perform an information synthesis to support development of a selenium monitoring program for North San Francisco Bay. The synthesis will support an integrated and strategic approach to monitoring in support of the selenium TMDL. Specific items to be covered include examination of the linkages between the three indicators (i.e., water column, sediment, and tissue), completing the development of the statistical framework for monitoring design and data evaluation, and consideration of analytical methods for long-term monitoring.
Study Description. This study will synthesize information from the DMMO database to evaluate PCB concentrations from dredging projects to compare the concentration ranges to other areas (e.g., open water and margin ambient sites), and to estimate the PCB mass removed from the Bay by dredging. The DMMO maintains a database that compiles sediment chemistry testing data from all Bay dredging projects. The DMMO has only recently released this database to the public. These data would provide valuable information to confirm the PCB total maximum daily load (TMDL) assessment that dredging results in a net PCB loss from the Bay and to leverage data already collected to evaluate the current conceptual model of Bay PCBs.

Study Description. The goal of the St. Tammany Parish Feasibility Study is to develop alternatives to reduce flood damages to St. Tammany Parish from riverine and coastal storm flooding. Potential flood risk reduction alternatives may include dredging, snagging and clearing, conveyance channels, levees, detention ponds, floodwalls/gates, pumping stations, non-structural efforts and engineering with nature efforts. Study Cost The study is fully federally funded through the BBA-18 at a total cost of $3M. Path Forward/Key Activities - Determine available information / data needs - Develop Project Management Plan - Develop Existing Conditions and Future Without Project Information - Develop Alternatives that can be assessed based on a rubric of screening criteria.
Study Description. The project consists of a Traffic Impacts Analysis (TIA) to determine if roadway or intersection improvements are needed within the City of Xxxxxxx Point to accommodate traffic from USGA’s 2023 U.S. Senior Open at SentryWorld. The project objective is to evaluate the existing operations of the study intersections, determine the intersection capacity to accommodate event traffic, and recommend improvements, if needed, to provide safe and efficient operations at the study intersections during the U.S. Senior Open at SentryWorld. The TIA will analyze potential impacts at the following intersections:
Study Description. This study was conducted using data from the InvolveMENt study, a recently completed, prospective cohort study.[24, 25, 26] The Emory University-‐led study was comprised of a computer-‐ based questionnaire and HIV/STI testing of black and white metro Atlanta MSM, and has current Emory University IRB approval. Venue sampling and convenience sampling through Facebook were used to recruit black and white MSM for the study. A variety of venues throughout Atlanta where MSM congregate were randomly chosen, and at the venues study staff systematically approached men to administer screening questions. Facebook sampling was achieved through paid advertisements directed towards men who were possibly eligible for the study. Recruitment took place between June 2010 and December 2012 during 605 sampling events at 94 individual venues. Eligibility requirements included being male at birth, being capable of completing the study instruments in English, self-‐reported white or black race, currently living in the metropolitan Atlanta area, having at least one male sex partner in the last three months, being 18 years of age or older, and providing at least two means of contact. Exclusion criteria included reporting Hispanic or Latino ethnicity, having plans to move out of Atlanta within the next two years, being in a mutually monogamous relationship with a man, or currently participating in any HIV prevention research study. Participants completed a computer assisted self-‐interview questionnaire at the baseline visit that included questions pertaining to demographics, psychosocial scales, community characteristics, individual-‐level HIV-‐related behaviors, and a dyadic inventory of the five most recent sex partners. Participants were also screened for HIV antibodies at each visit. At the baseline visit, participants were tested for syphilis, chlamydia, and gonorrhea. In addition, all participants were screened for biological markers of marijuana, cocaine, morphine, amphetamines, and methamphetamines at baseline. All participants who were confirmed to be HIV-‐negative at the baseline visit were then followed prospectively for two years to observe HIV and STI incidence. Those eligible returned for visits at 3, 6, 12, 18, and 24 months after the baseline visit, and the follow-‐up visits were conducted essentially the same as the baseline visit. Study participation ended after the 24-‐month visit or after HIV seroconversion.

Study Description. The calculation and monitoring of sediment loads entering San Francisco Bay are important for a variety of reasons, such as to inform dredging and tidal wetland restoration projects and to assess aquatic ecology, among others. While the information on sediment loads from many tributary sources is up-to-date, for other areas, such as the North Bay watersheds, there is little or no recent data. The objective of the work proposed herein, which the San Francisco Estuary Institute (SFEI) will carry out through the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) under Regional Water Board oversight, is to address this data gap by monitoring sediment loads at two existing USGS gages in the North Bay watersheds: 11458000 NAPA R NR NAPA CA, and 11458500 SONOMA C A AGUA CALIENTE CA. These two existing USGS gages currently monitor water flow rates following standard USGS methods. The addition of sediment load monitoring at these two gages is particularly important now because it will also provide information on sediment loads following the recent and extensive North Bay fires in these watersheds. Both gages have burned areas upstream. For this reason, it is critical that the monitoring begin as soon as possible. The scope and budget of this study assumes that the ongoing water flow rate monitoring at both sites will continue. The study will employ the following methods:
