Our Maps and GIS system (WebMap) uses Adobe's Flash Player. The plugin and ActiveX can be downloaded and installed from here.
Adobe Flash Player v22.214.171.124 will cause WebMap to fail. If rolling back to an earlier version, go back to v126.96.36.199. This beta release seems to fix it.
District Plan Maps
The District Plan is currently provided as static maps (available for download in our online District Plan). The District Plan is a legal document and the maps indicate data at the time of release. WebMap changes land parcels every month and they sometimes move dramatically.
