Nisich�4 SUBJECT: GOLF COURSE ROAD, TREVINO DRIVE AND VALLEY STREET - ENGINEERING AND TRAFFIC SURVEYS RESOLUTION NO. 94-76 DEPARTMENT: Community Development BACKGROUND At the request of the Sheriffs Department, the Traffic Engineering Division has conducted Engineering and Traffic Surveys on Golf Course Road between Tournament Road and Lochmoor Road, Trevino Drive between Tournament Road and Vista Fairways, and Valley Street between Happy Valley Drive and Maple Street. Under the California Vehicle Code Section 40802 (b), an "Engineering and Traffic Survey" is required where enforcement involves the use of radar or other electronic speed measuring devices. Our records indicate that speed limits (posted or non -posted) have not been established on these roadway segments. The speed limit normally should be established at the 85th percentile speed (defined as that speed at, or below, which 85 percent of the traffic is moving) or the nearest five miles per hour below it. However, in matching with existing conditions and traffic safety needs of the community, engineering judgement may indicate the need for a further reduction. The attached Vicinity Map (Exhibit "A" ) illustrates the proposed speed limits on the subject roadway segments. Based on the results of the Engineering and Traffic Surveys, the following speed limit are recommended on the subject roadway segments (staff report attached): Street Limits 85th Existing/ Percentile Recommended Posted Speed Speed Golf Course Rd. Tournament Rd. to Lochmoor Rd. None 36 mph 35 mph Trevino Dr. Tournament Rd, to Vista Fairways None 32 mph 25 mph Valley St. Happy Valley Dr, to Maple St. 25 mph 33 mph 25 mph Adopted: -gy Aw`_ ] Item:_40 RECOMMENDATION Staff recommends that the City Council adopt Resolution No. 94-76 to establish the speed limits on Golf Course Road between Tournament Road and Lochmoor Road, Trevino Drive between Tournament Road and Vista Fairways, and Valley Street between Happy Valley Drive and Maple Street.

Nisich, City Engineer FROM: Bahman Janka, City Traffic Engineer DATE: June 13, 1994 SUBJECT: GOLF COURSE ROAD, TREVINO DRIVE, AND VALLEY STREET - ENGINEERING AND TRAFFIC SURVEYS REQUEST At the request of the Sheriffs Department, we have conducted Engineering and Traffic Surveys on the following streets: Golf Course Road between Tournament Road and Lochmoor Road, Valley Street between Happy Valley Drive and Maple Street, and Trevino Drive between Tournament Road and Vista Fairways (private street). Each of the survey locations are illustrated in Exhibit "A". Under the California Vehicle Code Section 40802 (b), an "Engineering and Traffic Survey" is required where enforcement involves the use of radar or other electronic speed measuring devices. Our records indicate that speed limits (posted or non -posted) have not been established for the subject roadway segments. RECOMMENDATION Based on the results of the Engineering and Traffic Survey, the following prima facie speed limits are recommended at the subject roadway segments: 1. Golf Course Road between Tournament Road and Lochmoor Road 35 mph 2. Trevino Drive between Tournament Road and Vista Fairways 25 mph 3. Valley Street between Happy Valley Drive and Maple Street 25 mph CONDITIONS Golf Course Road between Tournament Road and Lochmoor Road - An east/west residential collector street with one travel lane in each direction. The street is 36 feet wide with curb/gutter and sidewalk on each side. The length of this street segment is about 900 feet long and intersects with five (5) streets. There are no driveways fronting the segment of the street. No intersection and midblock accidents were reported in 1993. Trevino Drive between Tournament Road and Vista Fairways - An east/west residential collector street with one travel lane in each direction. The street is 36 feet wide with curh/gutter on both sides of the street and sidewalk on the north side. The length of this street segment is about 2,200 feet long and intersects with four (4) streets including three (3) private streets. Also, a few driveways are fronting the street. Horizontal curves exist on this street. A public golf course is located along the south side of the street and separated by a chain -link fence. Three (3) intersection and one (1) midblock accidents were reported in 1993. Anthony J. Nisich June 13, 1994 Page 2 Valley Street between Happy Valley Drive and Maple Street - A north/south collector street with one travel lane in each direction. The street width varies from 24 to 50 feet and the major portion of the street segment has no curb, gutter and sidewalk improvements. The length of this street segment is about 2,000 feet long and intersects with five (5) streets. Private driveways are fronting the street. The existing posted speed limit on this street segment is 25 mph. The established and posted speed limits on Valley Street north and south of this street segment are 35 mph and 25 mph, respectively, A total of three (3) intersection and one (1) midblock accidents were reported in 1993. DATA Speed samples collected on the three subject streets are illustrated in the table below: 85th Recommended Street Percentile 10 Mile Pace M Sneed 1. Golf Course Road 36 mph 27 - 36 mph (82) 35 mph 2. Trevino Drive 32 mph 23 - 32 mph (84) 25 mph 3. Valley Street 33 mph 27 - 36 mph (89) 25 mph DISCUSSION The speed limit normally should be established at the 85th percentile speed (defined as the speed at, or below, which 85 percent of the traffic is moving) or the nearest five miles per hour below it. However, in matching with existing conditions and with the traffic safety needs of the community, engineering judgement may indicate the need for a further reduction. The following speed limits are recommended on the subject street segments in this study: Golf Course Road - Based on the 85th percentile speed, post the speed limit at 35 mph. Trevino Street - Based on the horizontal curves, fronting driveways and intersecting private streets, reduce the 85th percentile speed limit by 5 mph and post the speed limit at 25 mph. Valley Street - Based on unimproved curb, gutter and sidewalk, variation of roadway, width, fronting driveways and consistent with speed limits on surrounding streets, reduce the 85th percentile speed limit by 5 mph and post the speed limit at 25 mph.
