COORDINATION

LAPD concurred with the proposed speed limit changes in a letter to the Department dated December 14, 2006. The Department of Transportation also sent a letter to Councilmember Smith on January 30, 2007 notifying him of the proposed changes.

DISCUSSION

An engineering and traffic survey has been completed for Parthenia Street between Sepulveda Boulevard and Topanga Canyon Boulevard as required by Vehicle Code Section 40802(b), in order to justify enforcement of the speed limit by radar. The attached Engineering Report summarizes the findings of the engineering and traffc survey and the basis for the recommended speed limits. The survey indicated that speed limits of 40 and 45 miles per hour are consistent with traffic conditions and driveway characteristics and will facilitate the safe and orderly movement of traffic.

2 ENGINEERING REPORT

Engineering and Traffc Survey for Parthenia Street between Sepulveda Boulevard and Topanga Canyon Boulevard

-Parthenia 'Street -between its terminus at Topanga Canyon Boulevard and Sepulveda Boulevard is a designated secondary highway with a total length of 7.8 miles. The existing posted speed limits along Parthenia Street are asfollows:

. between its terminus at Topanga Canyon Boulevard and Mason Avenue, the posted speed limit is 35 rniles per hour (m.p.h.), . between Mason Avenue and Tampa Avenue, the posted speed limit is 40 m.p.h., . between Tampa Avenue and Reseda Boulevard, the posted speed limit is 35 m.p.h., . between Reseda Boulevard and Sepulveda Boulevard, the posted speed limit is 40 m.p.h., and . east of Sepulveda Boulevard, the posted speed limit is 35 rn.p.h.,

Between its terminus at Topanga Canyon Boulevardand De Soto Avenue, a distance of approximately O.g miles, all of the observed critical speeds on Parthenia Street range from 39 and 41 m.p.h. According to the requirements for setting speed limits described in the California Supplement to the 2003 Manual on Uniform Traffc Control Devices (MUTCD), the speed limit on this segment of Parthenia Street should be set at 40 m.p.h. There do not appear to be any factors readily apparent to drivers that would justify a reduction in the speed limit.

Between De Soto Avenue and Tampa Avenue, a distance of approximately 1.9 miles, all of the observed critical speeds on Parthenia Street range from 44 and 46 m.p.h. According to the requirements for setting speed limits described in the California Supplement to the 2003 MUTCD, the speed limit on this segment of Parthenia Street should be set at 45 rn.p.h. There do not appear to be any factors readily apparent to drivers which would justify a reduction in the speed limit.

Between Tampa Avenue and Lindley Ayenue, a distance of 1.5 miles, 83 percent of the observed critical speeds on Parthenia Street range between 40 and 42 m.p.h. According to the requirements for setting speed limits described in the California Supplement to the 2003 MUTCD, the speed limit on this segment of Parthenia Street should be set at 40 m.p.h. There do not appear to be any factors readily apparent to drivers that would justify a reduction in the speed limit.

Between Lindley Avenue and Haskell Avenue, a distance of 2.9 miles, all of the observed critical speeds on Parthenia Street range between 43 and 46 rn.p.h. According to the requirements for setting speed lirnits described in the California Supplement to the 2003 MUTCD, the speed limit in this segment of Parthenia Street should be set at 45 m_p.h. There do not appear to be any factors readily apparent to drivers which would justify a reduction in the speed limit. Engineering Report 2 Parthenia Street

Between Haskell Avenue and Sepulveda Boulevard, a distance of 0.5-mile, the observed critical speeds were 43 and 45 m.p.h. According to the requirements for settng speed limits described in the California Supplement to the 2003 MUTCD, the speed limit on this segment of Parthenia Street should be set at 45 m.p.h. However, approximately 9.6 - percent of-he injury accidents (26 out of 272), during the most recent 24-month period have occurred in this section of the roadway which is only about 6 percent of the total surveyed route. The injury accident rate can be calculated to approximately 3.41 acc/mvm for this 0.5-mile segment of Parthenia Street. This disproportionate concentration of injury accidents in this segment of roadway combined with a higher than average overall injury accident rate of 3.41 acc/mvm indicate that the prevailing speeds are not as safe as speeds in the remainder of the study section. This factor described above (high concentration of injury accidents) creates safety concerns at the speeds that drivers are currently traveling in this segment. Therefore, a reduction of five miles per hour is justified, reducing the recommended speed limit from 45 m.p.h. to 40 m.p.h.

Therefore, for the reasons described above, the Department recommends that the speed limits on Parthenia Street be as follows:

. between Topanga Canyon Boulevard and De Soto Avenue, the speed limit be increased from the existing 35 m.p.h. to 40 m.p.h., . between De Soto Avenue and Mason Avenue, the speed limit be increased from the existing 35 m.p.h. to 45 m.p.h., . between Mason Avenue and Tampa Avenue, the speed limit be increased from the existing 40 m.p.h. to 45 m.p.h., . between Tampa Avenue and Reseda Boulevard, the speed limit be increased from the existing 35 m.p.h. to 40 m.p.h., . between Reseda Boulevard and Lindley Avenue, the 40 m.p.h. speed limit be retained, . between Lindley Avenue and Haskell Avenue, the speed limit be increased from the existing 40 m.p.h. to 45 m.p.h., and . between Haskell Avenue and Sepulveda Boulevard, the 40 m.p.h. speed limit be retained.
