No changes are recommended in the segment of Ham Lane from Tokay Street to Lodi Avenue. BACKGROUND INFORMATION: At the January 17, 2001 meeting, City Council approved the elimination of street parking on Ham Lane from Cardinal Street to Vine Street to accommodate a continuous two-way left turn lane. Also at that meeting, Council directed staff to review extending the turn lane north of Vine Street to Lodi Avenue. The following are the results of that study. Staff's review of accidents occurring between Vine Street and Lodi Avenue for the five-year period from 1996 to 2000 indicates that the most prevalent type of accident involved left turning vehicles (Exhibit B). Of the 42 total accidents occurring along this segment (excluding signalized intersections), twenty-three (about 55%) were associated or likely associated with left turning vehicles on Ham Lane. Seventeen of these turn related accidents occurred in the segment from Vine Street to Tokay Street, with the remaining six between Tokay Street and Lodi Avenue. These turn related accidents include left -turn versus through and rear -end accidents where drivers are hit while stopped waiting to turn left. To determine how this segment compared to other portions of Ham Lane, staff evaluated conditions between all the signalized segments of Ham Lane between Cardinal Street and Elm Street. The portion of Ham Lane south of Lodi Avenue is currently striped with two through lanes in each direction with turn pockets only at signalized intersections. North of Lodi Avenue to Elm Street, there is one through travel lane in each direction separated by a continuous left turn lane. When comparing only left turn related accidents, while numerous accidents occurred south of Lodi Avenue, there were no reported left turn accidents occurring north of Lodi Avenue to Elm Street. Even though there are numerous private driveways and cross street intersecting this segment, this absence of left turn related accidents was expected because there is an existing continuous left turn lane. However, when other types of accidents are considered, the segment north of Lodi Avenue had the most right angle and non -turn related rear -end accidents. These types of accidents can be attributed to congestion created by the relatively high traffic volumes confined to a single travel lane in each direction. High incidents of right angle accidents are typically caused by the lack of gaps in cross street traffic; and rear -end accidents can be attributed to unexpected stopping conditions created by long lengths of backed -up traffic. Accident rates for the segments reviewed are shown on Exhibit C. Based on the results of our review of Ham Lane, the following two alternatives are presented. Another alternative reviewed, but not considered, was to add the continuous left turn lane and reduce the number of through travel lanes to APPROVED: H.

Although this layout would reduce rear -end accidents related to left turning vehicles, rear -end accidents related to long lengths of backed -up traffic are likely to increase as they create unexpected stopping conditions. Drivers on Ham Lane turning left into private driveways or cross streets will also likely experience difficulty due to the fewer gaps available in opposing traffic created by confining all the traffic into one lane. Drivers entering Ham Lane from private driveways and cross streets will experience similar difficulties created by the reduction of gaps in traffic. Reducing the number of travel lanes would likely result in a reduction of left turn related accidents and increase in congestion related accidents as demonstrated in the two-lane segment between Lodi Avenue and Elm Street. Install solid, raised median (no openinns) — This alternative would eliminate left -turn related accidents on Ham Lane; however, it would also affect traffic exiting from cross streets and driveways. While daily traffic volumes on Ham Lane are relatively high, approximately 15,000 vehicles per day, a median is not warranted at this time. Medians are generally considered when, among other factors, daily traffic volumes for a four -lane roadway exceed 22,000 vehicles per day. A disadvantage of restricting turning movements with a median is the circuitous traffic patterns and increased U-turns at median openings. These issues will need further study if this alternative is preferred. Install Continuous left -turn lane — This alternative should reduce rear -end accidents because it provides a separate lane for turning vehicles. It should also reduce turn -related accidents because left -turning drivers will not feel rushed by traffic approaching from behind. The turn lane can also be used as a refuge area when entering Ham Lane from cross streets or private driveways. Although the advantages to turn lanes are significant, a disadvantage is the elimination of street parking. The review of accidents along this segment indicate that there were many more left turn related accidents in the portion of Ham Lane between Vine Street and Tokay Street than Tokay Street and Lodi Avenue. A modification to this alternative could be to not install the continuous left turn lane in the portion between Tokay Street and Lodi Avenue. However, an additional benefit the turn lane would provide in this particular area is to eliminate the weaving that can occur because the number of northbound lanes on Ham Lane reduces from two to one north of Lodi Avenue. Due to this configuration, when northbound drivers intending on crossing Lodi Avenue encounter traffic stopped to turn left into a private driveway, many will swerve around the stopped vehicles into the adjacent travel lane then quickly back again before reaching the intersection. The installation of a continuous left turn lane would help alleviate this weaving action. DISCUSSION: Prior to this meeting, staff contacted the affected property owners and tenants regarding our proposal to remove parking to install this traffic safety improvement. Our inquiry resulted in numerous responses. While the benefit of the turn lane was understood, the loss of street parking was the main concern. Staff surveyed parking along this segment on eighteen occasions at various times of the day. The average number of parked vehicles observed was ten, with the highest being eighteen. During nearly all of the surveys performed there was sufficient on-site or side street parking available to accommodate the number of vehicles observed parked on -street, with the exception of at La Espana Apartments, who's parking lot is posted to prohibit visitor parking. The property owner, manager, and residents have expressed concerns over the need for street parking for visitors, family, caregivers, etc. Concerns over loss of parking were also received from two office complexes. At 801 S. Ham Lane, concerns were expressed due to existing vacant suites in the complex, which will create the need for additional parking once occupied. Vienna Convalescent hospital also expressed concerns over the loss of parking for visitors and employees. Based on the results of the study, staff favors installing a continuous left -turn lane on the portion of Ham Lane from Vine Street to Tokay Street. The portion of Ham Lane from Tokay Street to Lodi Avenue is not being recommended at this time due to the relatively low number of left turn related accidents. Staff did review areas where parking concerns were expressed to determine if it was possible to create additional parking. In front of La Espana Apartments, parking for eight to nine vehicles can be created by constructing an inset adjacent to the curb that would basically widen a portion of their frontage to accommodate parked vehicles; however the cost would be about $25,000 and some right-of-way would have to be acquired. If the apartment's concerns can be mitigated, staff CHAMTURNLN Adopt a Resolution Approving No -Parking Zones on all or portions of Ham Lane from Vine Street to Lodi Avenue, to Accommodate the Installation of a Continuous Two -Way, Left -Turn Lane March 21, 2001 Page 3 would recommend that the continuous left turn lane be extended from Tokay Street to Lodi Avenue, since no others expressed parking concerns in this segment. However, staff would recommend that the owners dedicate the necessary right-of-way and pay for all or a substantial portion of the construction cost. Of the areas between Vine Street and Tokay Street where concerns were received, the only location staff observed where any additional parking could be added was by utilizing a portion of the property east of the convalescent hospital on Sylvia Drive. However, since the parcel is not owned by the hospital, and there is available parking off-street, staff feels this matter should be settled between the two property owners. FUNDING: Funding for the installation of no -parking signs and striping modifications from Measure K, Non -Competitive Funds at an approximate cost of $12,400.
