Interactive Trail Maintenance Map
We work hard to maintain the integrity of Tri-Valley’s flood protection system to keep our community safe from flooding. Due to both environmental regulations and weather conditions, most of this construction work is limited to the warm, dry season. Doing this important work safely means occasional impacts to trails are necessary. In order to minimize the impact of trail closures and detours on our community, our staff updated and improved the interactive trail maintenance map so residents can now view, in real-time, the season’s planned, active and completed construction projects. Please note this map does not reflect closures due to immediate weather and storm damage.
