This segment of Winston Avenue meets the requirements of CVC 515 for a “Residence District” that within a distance of a quarter mile, the contiguous property fronting on both sides is occupied by 16 or more separate dwelling houses or business structures. For streets longer than a quarter mile, it exceeded the above ratio proportional to the street length. This segment has 99 dwelling houses fronting the street over 0.89 miles, which exceeds the ratio of 57 dwelling houses to street length per CVC 515. It is recommended that this segment be designated as a “Residence District” with a 25 MPH speed limit. This segment does not require continued speed survey.
