Authorize staff to work with residents of Langside Avenue and Meadowcreek Road to install speed cushions on their streets, as determined by additional traffic studies. 4. Authorize the sole source purchase of speed cushions and related materials from Traffic Logix, Inc., in an amount not to exceed $70,000. 5. Increase Gas Tax Miscellaneous Revenue Account 230-4621.001 by $30,000, and increase General Fund Miscellaneous Revenue Account 100-4621.001 by $70,000. 6. Appropriate $30,000 to Street Maintenance Expenditure Account 14504-5201.002 and appropriate $70,000 to Traffic Admin Expenditure Account 14400-5161.001. BACKGROUND As a condition of the Five Knolls development, the developer was required to complete Golden Valley Road between Newhall Ranch Road and Dorothy Street (the connection at Dorothy Street is within the unincorporated area of Los Angeles County). While this new roadway connection has resulted in changes to traffic patterns within the existing adjacent neighborhood, these changes were anticipated during the Five Knolls entitlement process. Page 1 PacketPg. 70 The project developer was conditioned to provide for traffic -calming features on Dorothy Street and Ermine Street and within the surrounding neighborhood to the satisfaction of the Director of Public Works. The City of Santa Clarita (City) determined this condition could be satisfied with the payment of an in -lieu fee in the amount of $100,000 to be utilized by the City for the installation of traffic -calming features along the subject streets. In anticipation of its completion and subsequent opening, staff recently collected traffic data within the adjacent residential neighborhood before and after the completion of Golden Valley Road. The data indicated traffic volumes increased from 1,650 vehicles per day to 3,250 vehicles per day on Dorothy Street just east of Golden Valley Road. Ermine Street opened to traffic to access Golden Valley Road on February 3, 2016. Traffic volumes on Ermine Street just east of Golden Valley Road quickly rose from 220 vehicles per day to 1,260 vehicles per day. The opening of Ermine Street did provide some relief to the traffic on Dorothy Street, as the traffic volume fell to 2,870 vehicles per day. Attachment 1 illustrates the changes in daily traffic volumes and vehicular speeds on Dorothy Street and Ermine Street. Consequently, City staff developed a comprehensive traffic -calming plan to address these changes in traffic patterns. This plan includes four new multiway stop -controlled intersections, three of which were previously approved by City Council on January 12, 2016 (Langside Avenue at Ermine Street, Langside Avenue at Dorothy Street, and Dorothy Street at Florence Lane), and the installation of 12 sets of speed cushions. Staff is proposing making the intersection of Ermine Street and Northbrook Avenue the fourth multiway stop -controlled intersection. Staffs evaluation determined the installation of multiway stop controls at this intersection would improve safety and traffic operations. This location is also compatible with the three previously installed multiway stop -controlled intersections. In addition to the proposed multiway stop controls, the installation of speed cushions will further enhance traffic safety and circulation within the neighborhood. Attachment 2 illustrates the proposed traffic -calming plan. An invitation letter and a reminder letter were sent in advance to the affected residents regarding a public meeting, held on January 13, 2016, at Skyblue Mesa Elementary School. All homes fronting Ermine Street and Dorothy Street between Golden Valley Road/Langside Avenue and Langside Avenue between Dorothy and Ermine Streets received these notices, samples of which are attached as Attachments 3 and 4. Approximately 40 people attended and viewed exhibit stations with information about traffic volumes, vehicle speeds, future speed humps, stop sign locations, and their design and construction in this area. City staff was available to explain the plan and answer any questions. Two Los Angeles County staff members, including a representative from the Board of Supervisors Fifth District office, attended and supported the event (as a portion of the impacted community is in unincorporated Los Angeles County). The attendees were highly in favor of the proposed traffic -calming measures and locations as prepared by staff. Some questions and suggestions were raised at the public meeting via comment cards, a petition, a submitted letter, and dialogue with staff. Following the public meeting, a letter summarizing the outcome of the meeting was sent to the affected residents on January 26, 2016. The letter indicated staff would be implementing the Page 2 Packet Pg. 71 same traffic -calming measures, as illustrated at the meeting, and provided for a comment period. In addition, the residents were notified this matter would be presented to the City Council on March 8, 2016. The letter included diagrams illustrating traffic and speed data, the locations of proposed speed cushions and stop signs, and construction details of the proposed speed cushions. A copy of this letter is attached as Attachment 5. Residents were requested to contact staff if they had any comments or concerns regarding the plan. In follow up to this letter, the City received calls from three residents with questions and additional requests. Staff plans to review the conditions after the implementation of the traffic -calming plan and take further action as necessary. The Los Angeles County Department of Public Works, Traffic and Lighting Division have also shown support for this traffic -calming plan. They indicated no additional approvals are necessary from their Board of Supervisors. hi addition, staff received no notices or objections from the local offices of the Los Angeles County Fire Department, after bringing this proposed traffic - calming plan to their attention. Upon approval by the City Council, City staff will proceed with ordering the necessary supplies to install the 12 speed cushions at locations for both the City and County jurisdictional areas. The speed cushions will be made as a sole source order from Traffic Logix, Inc., of Spring Valley, New York. The sole source order will be made, as this product was used successfully within the Benz Road/Alaminos Drive neighborhood, City staff is familiar with the installation process, and the City would have one consistent product to maintain and keep an inventory of materials. A photo of a typical installation of the Traffic Logix type speed cushions is included as Attachment 7. Of the $100,000 collected from the developer of the Five Knolls residential neighborhood, $70,000 will be used to cover the costs of materials and $30,000 will be used to cover the costs of additional equipment needed to implement the traffic -calming plan. Installation of the devices is anticipated to occur by the end of May 2016. ALTERNATIVE ACTION Other action as determined by the City Council. FISCAL IMPACT Adequate funds in the amount of $100,000 are available in Trust and Agency Cash -in -Lieu Account 102-2013.001. Upon approval of the recommended action, the budget will be adjusted accordingly.
