Basis of Recommendation
This segment ofLa Porte Rd. qualifies as both Residential and Business Districts as defined in the California Vehicle
Gode and as such the Prima Facie Speed Limit of 35 mph shall apply per this Engineering and Traffic Survey (CVC627)
1. The multiple driveway entrances fronting the roadway require vehicles to maneuver into Traffic when entering
and exiting the residences.
2. The limited sight distances for vehicles entering onto La Porte Rd. require that the roadway be posted no greater
than 35 mph.
3. Speeds higher than recommended contribute to hazard of driver overcorrection in efforts to remain on pavement
with narrow lane widths and unimproved shoulders.
Therefore, it is concluded that the maximum safe speed, and the proposed prima facie speed limit of 35 mph should
be enforced per CVC Section 22352{2)A. It is recommended that additional enforc ent be staged between 5:04 AM
and 7:44 PM. ~~~~$s1Q
