That the City Council approve the Engineering and Traffic Survey dated September 16, 1987 as prepared by Dennis Barnes, Consulting Traffic Engineer of BSI Consultants, Inc. 2. That the City Council adopt an ordinance establishing speed zones on certain streets. BACKGROUND Section 40802 of the Vehicle Code provides that an engineering and traffic survey must be prepared to justify speed limits. The survey must be done every five years or radar cannot be used for enforcement. BSI Consultants, Inc., the City's traffic engineering consultant, has prepared the survey, a copy of which is attached. The Police Department Traffic Section has reviewed the survey and concurs with its recomendations. Each year about 20% of the City's arterial streets are surveyed so that all will be covered during a 5-year period. The recommended ordinance covers only those streets included in this year's survey. The survey recommends the following speed limits: Street HOLT AVENUE Irvine Boulevard to Warren Street Current Speed Limit Recommended Speed Limit Not posted 40 NEWPORT AVENUE Sycamore Avenue to Walnut Avenue Walnut Avenue to E1 Camino Real E1 Camino Real to Wass Street 35 35 40 35 35 35 PASADENA AVENUE Sycamore Avenue to McFadden AVenue Not posted 35 RED HILL AVENUE Barranca Road to Edinger Avenue 5O 5O Bob Ledendecker Director of Public Works/City Engineer UL/mV Ronald E.

MAYOR A1-FEST: CITY CLERK CONSULTANTS, INC. Consultants to Governmental Agencies September 16, 1987 City of Tustin Attention Mr. Bob Ledendecker Director of Public Works 300 Centennial Way Tustin, California 92680 Engineering and Traffic Survey for Fifteen (15) Street Seqments Within the City of Tustin As requested, engineering and traffic surveys have been completed for several routes in the City of Tustin. Therefore, I am pleased to submit ,this letter-type report which contains recommendations for posted prima facie speed limits on the 15 street segments surveyed. The California Vehicle Code requires that engineering and traffic surveys be conducted every five years to enable the continued use of radar for speed enforcement. These engineering and traffic surveys include measurements of prevailing speeds, an analysis of accident records, and a review of highway, traffic and roadside characteristics which are not apparent to motorists. However, in accordance with California Vehicle Code provisions, local streets which are not included on the City's Federal Aid Urban (FAU) Select System of Streets are exempt from the survey requirements. Since the last engineering and traffic survey for the subje- ct streets was conducted during the month of May Df 1982, a new survey has been conducted so that radar enforcement can. continue. The individual surveys for each of the 15 street segments involved the following factors¢ 1. Field radar speed measurements consisting of a total of 100 vehicles for each roadway now striped for four or more travel lanes and a total of 50 vehicles for each segment having two marked travel lanes were made. Field tally sheets included engineering calculations of the average or mean speed, the 85th percentile or critical speed, and the 10 mile per hour pace speed containing the greatest number of observations. 1415 East 17th Street. Santa Ana, California 92701 · [714) 558-1952 A Berryman & Stephenson Industries Company City of Tustin -2- ~ptember 16,1987 Mr. Bob Ledendecker 2. Accident records for each street seg~t~ent for the-last three years were reviewed and summarized. Accident frequencies were then compared with studies published by other agencies to dete=mine if the accident experience is higher or lower than other similar roadways. 3. Highway, traffic and roadside characteristics which are not readily apparent to motorists were determined based upon a field review of each segment. Characteristics noted included the number of travel lanes, frequency of driveways, density of on-street parking, predominate land use, crosswalks, horizontal and vertical alignment, and traffic controls. The previous information was gathered and summarized on a survey sheet for each street segment. Recommendations for speed limits based upon the current prevailing conditions were then developed. Attached is a summary listing for the fifteen segments which were surveyed within the City. The listing indicates the current posted speed limit and the recommended posted speed limit. As noted, no changes are recommended on ten (10) of the street segments. Howeve~r, three street segments are recommended for a decrease of five miles per hour from the present speed limit and two new street segments are recommended to be posted. In addition to the summary listing, the survey sheets for each street segment are attached for your files. Recommended Action It is recommended that this specific Engineering and Traffic Survey report be forwarded to City Council for their approval. Further, staff should be instructed to prepare an Ordinance to amend the City's Municipal Code for the City Council's consideration. After approval, the city Clerk should be directed to file a copy with the appropriate authorities for enforcement and prosecution purposes. Sincerely yours, BSI CONSULTANTS, INC. Dennis D.
