This is the Los Altos-specific Damage Assessment Summary form. This is an add-on to the Santa Clara County's Outpost packet message manager program. You must install this package from the County's website first. See the County's page at https://www.scc-ares-races.org/data/packet/client-software.html
The Los Altos Damage Assessment Summary form is graciously maintained by John W6JMK. To download the latest Damage Assessment Summary form, follow this link. Save the setup file to a well known place (such as your Desktop), then double-click on it to run/install the form.
