The estimate for CHP effective staffing for El Dorado Hills surface streets is a personal estimate based on (1) CHP Placerville office staffing; (2) Coverage area, which recently rose above 1,000 miles of roads on the west slope; (3) Known shift-specific staffing rates in the area:  Usually a maximum of 2 units from the Sacramento County line to Ponderosa Road (daytime) and a minimum of 1 unit to cover the entire west slope (graveyard shift);  (4) known need for CHP to support service on US 50 first, reducing ability to patrol surface streets; (5) known need for substantial CHP workload to respond to accidents and DUI arrests; (6) frequency of sightings of CHP on surface streets, in comparison with known CHP duty cycle of 6 hours patrol per week in Waterford, funded by the HOA through a Reimbursable Services Agreement. (Funding is for 8 hours per week 2 hours are commute time between Placerville and El Dorado Hills.)
