Based on the results of this speed survey, staff has determined that the speed limit on Brandywine Avenue between Olympic Pazkway and East Palomaz Street should be increased from 35 mph to 40 mph (see Attachment 1, Location Plat). ENVIRONMENTAL REVIEW The Development Services Director has reviewed the proposed project for compliance with the California Environmental Quality Act (CEQA) and has determined that the project qualifies for a Class 1 (c) categorical exemption pursuant to Section 15301 (Existing Facilities) of the State CEQA Guidelines because the proposed project consists of increasing the posted speed limit on an existing street resulting in negligible or no expansion of the street use. Thus, no further environmental review is required. RECOMMENDATION Council place Ordinance on first reading. BOARDS/COMMISSION RECOMMENDATION The Safety Commission, at their meeting on June 5, 2013, voted (4-0-3) to concur with staffls recommendations to increase the posted speed limit from 35 mph to 40 mph on Brandywine Avenue, between Olympic Parkway and East Palomar Street. 3-1 7/16/13, Item Page 2 of 4 DISCUSSION ENGINEERING AND TRAFFIC SURVEY City Staff completed a speed survey along a segment of Brandywine Avenue between Olympic Pazkway and East Palomaz Street in accordance with the Califomia Vehicle Code which indicates that the posting of speed limits be determined by an Engineering and Traffic Survey (E&TS) (see Attachment 2). As described in the California Vehicle Code, the survey shall include: (1) Prevailing speeds as determined by traffic engineering measurements; (2) Accident records; (3) Traffic/roadside conditions not readily appazent to the driver. These roadway characteristics aze then used to help determine an appropriate speed limit. In addition, the Manual on Uniform Traffic Control Devices (MUTCD) states that the speed limit shall be established at the nearest 5 mph increment of the 85a' percentile speed. In addition, if the 5 mph reduction procedure is applied, the Engineering and Traffic Survey shall document in writing the conditions and justification for the lower speed limit and be approved by a registered Civil or Traffic Engineer. Speed limits established on the basis of the 85a' percentile speed conform to the consensus of those who drive the street as to what speed is reasonable and safe, and aze not dependent on the judgment of one or a few individuals. Speed limits posted higher than the 85a' percentile speed aze not generally considered reasonable and safe while speed limits posted below the 85a' percentile typically do not facilitate the orderly movement of traffic. Only when roadside development results in traffic conflicts or unusual conditions not readily appazent to drivers may speed limits be further reduced. The Engineering and Traffic Survey (E&TS) determined that the 85'x' percentile speed on Brandywine Avenue between Olympic Pazkway and East Palomar Street is 39 mph. Per speed limit establishment protocol, this was measured during the off-peak hours under normal driving conditions, as required per the MUTCD. SAFETY COMMISSION MEETING On June 5, 2013, the E&TS was brought before the Safety Commission for their consideration. The Safety Commission approved staffls recommendations to increase the speed limit on Brandywine Avenue between Olympic Parkway and East Palomaz Street from 35 mph to 40 mph (see Attachment 3). In addition, the Safety Commission approved the recommendation to revise Schedule X of the register maintained in the office of the City Engineer. Also, the Safety Commission approved staffs recommendations to add more speed limit signs with pavement legends be added including the installation of a flashing beacon by Fire Station No. 3 which is located along Brandywine Avenue. 3-2 7/16/13, Item =' Page 3 of 4 Physical Conditions Brandywine Avenue between Olympic Parkway and East Palomar Street is 2,411 feet (0.46 miles) long and 64'-80' wide curb-to-curb with a striped median. The street is classified as a 4- Lane Major. The street has bike lanes on both sides of the road. There is no pazking allowed along the entire segment, except along 200' of the easterly side of Brandywine Avenue north of Olympic Parkway. This is to accommodate three (3) single-family dwellings fronting Brandywine Avenue with direct driveway access. The following table describes the existing conditions along the segment of Brandywine Avenue: Segment Limits Brandywine Avenue between Olympic Parkway and East Palomar Street Len h/Width 2,411 feet (0.46 miles)/ 64'-80' wide curb to curb with a stri ed median Classification 4-Lane Ma or ADT ear 12,503 (2008) Exist. S eed Limit Posted 35 m h 85` % S eed 39 m h between Ol m is Pazkwa and East Palomar Street Number of Lanes 4 total lanes (2 per direction). 4 lanes, right-turn and left-turn pockets, crosswalks, limit lines and bike Striping ]apes. Parking and Bike No parking allowed with bike lanes, except along 200' of the easterly Facilities side of Brandywine Avenue north of Olym is Parkway. Land Use Residential. A horizontal curve with a radius of 1100 ft over a length of 792 ft Horizontal Alignment roduces a desi n s eed of 55 m h. A crest vertical curve over a distance of 500 ftwith a -2.00% to -7.00% Vertical Alignment grade difference produces a design speed of 45mph. The accident rate at this segment is 0.48 (accidents per million vehicle Accident Rate: miles) and is lower than the rate of 1.93 for similar roadways in the State Segment /State of California (2010). Fire Station located within the segment Three single-family dwellings Special Conditions with direct driveway access on east side of Olym is Pazkwa . CONCLUSION When speed limits are appropriately established (set at the 5 mph increment of speed in the upper half of the normal pace of traffic (85th percentile)) the following objectives aze achieved: - Meaningful, unambiguous enforcement - Voluntary public compliance - Cleaz identification of the unreasonable violator - Elimination of unjustifiable "tolerances" of higher speed travel Based on the 850i percentile speed of the roadway, as well as a low collision rate outlined in the E&TS, staff has determined that the speed limit on Brandywine Avenue should be increased to 40 mph from Olympic Pazkway and East Palomar Street. Retaining the 35 mph speed limit 3-3 7/16/13, Item 3 Page 4 of 4 makes a significantly high proportion (67%) of motorists be considered as violators and based on the study findings it is not justified. Should the City Council establish the proposed 40 mph speed limit, Schedule X of the register maintained in the office of the City Engineer would be amended to reflect the revised speed limit as follows: 10.48.020 Schedule X -Established Speed Limits in Certain Zones -Designated Name of Street Beginning At Ending At Proposed Speed Limit Brandywine Avenue Olympic Parkway East Palomar Street 40 mph DECISION MAKER CONFLICT Staff has reviewed the property holdings of the City Council and has found no property holdings within 500 feet of the boundaries of the property, which is the subject of this action. Staff is not independently aware, nor has staff been informed by any City Council member, of any other fact that may constitute a basis for a decision maker conflict of interest in this matter. CURRENT YEAR FISCAL IMPACT The proposed speed limit modification would require the replacement and posting of new speed limit signs, marking of new speed legends, and the installation of a flashing beacon. The proposed modification, at a total cost of approximately $11,205, will be installed once the Ordinance is in effect. This cost will be funded by an existing Traffic Engineering Capital Improvement Project, TF-332, Signing and Striping Program, which is funded by TransNet. Therefore, there is no direct impact to the General Fund. ONGOING FISCAL IMPACT Upon completion of the project, the improvements will require minor routine maintenance of the street facilities.
