    • 06: Property parcel building construction dates and densities in 15 watersheds in Gwinnett County, Georgia in 2021

    Metadata Updated: October 30, 2025

    This dataset contains the number of buildings and their construction dates within the 15 study watersheds in Gwinnett County, Georgia. Dataset reflects existing buildings as of October 2021 and construction dates range from 1810 to 2021. The dataset was created by matching parcel boundaries obtained from Gwinnett County with building construction dates from the Gwinnett County Cadastral database. Building densities were calculated for each watershed and year to estimate temporal changes in watershed building densities.
