Street Pavement Condition

The annual, street pavement condition index of the unincorporated areas of Marin County. Data starts in 2003 and is updated annually. Pavement condition is measured using the Pavement Condition Index (PCI), as described below. "Pavement condition index (PCI) relies upon a three-year moving average for regional, county, and city PCI to improve the reliability of the PCI data on an annual basis. The index ranges from 0 to 100, with 0 representing a failed road and 100 representing a brand-new facility. Segment PCI data is collected on a rolling basis but is imputed for interim years based on facility age and treatments using the MTC StreetSaver system."

COVID-19 Case Disposition (archived)

This dataset has been retired as of February 17, 2023. This dataset will be kept for historical purposes, but will no longer be updated. Similar data are available on the state’s open data portal: https://data.chhs.ca.gov/dataset/covid-19-time-series-metrics-by-county-and-state/resource/e2c6a86b-d269-4ce1-b484-570353265183. This dataset provides the daily & cumulative number of COVID-19 new confirmed cases, hospitalizations, and deaths among Marin County residents (does not include San Quentin inmates). Event Date corresponds to date that each status type occurred. For Confirmed Case this is Test Date, for Hospitalized this is Hospital Admit Date, and for Death it is the Date of Death. If a person first tested positive for COVID-19 on 11/1/2020, was admitted to the hospital on 11/15/2020, and died on 11/20/2020, their data would be contained in three rows for each status and event date. Note: as of 11/2/2021 hospitalization counts no longer includes in-patient hospitalizations with a COVID-19 positive test when the patient was in the hospital for a reason other than COVID-19. This can include in-patient stays due to labor/delivery, trauma, or emergency surgery. The previous definition of COVID-19 hospitalizations, counting all in-patient hospitalizations with a COVID-19 positive test, measured the burden of disease on hospital resources, while this updated definition is a more appropriate measure of disease severity among Marin County residents. Cases are lab-confirmed COVID-19 cases reported to Marin County Public Health by providers, commercial laboratories, and academic laboratories, including reporting results through the California Reportable Disease Information Exchange.</strong> A lab-confirmed case is defined as detection of SARS-CoV-2 RNA in a clinical specimen using a molecular amplification detection test.
