Wineholt, Merrit Inc., 8950 Villa La Jolla Jolla, CA 92037, agent Homeowners Association. Property Management, Dr., Suite 212, La for Colinas De Oro The Colinas De Oro Homeowners Association is requesting a stop sign to be installed at the corner of Calle Madrid and Calle San Felipe. DATA: A field review of the site was conducted and a turning movement count recorded on November 5, 1986 (see attached sketch). The traffic study conducted at the intersection found low traffic volumes, very little pedestrian activity and adequate visibility in all directions. There have been no reported accidents within the last twelve (12) months. The purpose of a stop sign is to control the right-of-way assignment at an intersection. Properly installed, the stop signs facilitate traffic movement and promotes traffic safety. At this location, however, none of the warrants for a stop sign are met by the existing conditions (warrants attached). Unwarranted stop signs generally result in an increase in traffic accidents and should not be installed at the unwarranted location. RECOMMENDATION: The Traffic Safety Coordinating Committee the request for a stop sign be denied. NECESSARY COUNCIL ACTION: recommends that None required if the request is denied. An ordinance will be required to be adopted by the City Council if the stop sign _is recommended. - October 28, 1986 • Traffic Commission City of Carlsbad 1200 Elm Avenue Carlsbad, Cl\ 92008 Dear Sir or Madam: A MERIT PROPERTY MANAGEMEN1 INC.

Stop signs shall be erected on both the left and right side of one-way roadways which are 30 feet ormore in width. Stop signs shall not be installed at signalized intenections. Conditions warranting SI'OP signs are: 1. On, the less important road at its intenection with a main road where application of the nor• mal right of way rule is unduly hazardous u evidenced by ac:c:idents susceptible of correc- tion by STOP signs. 2. On a county road or city street at its inlersec• tiom with a state highway. 3. Al the intersection of two main highways. The highway traffic to be stopped depends on ap- proach speeds. volumes, and tumial move- ments. 4. On a street entering a legally established through hi1hway or street. 5. On a minor street where the safe approach speed to the intersection is less than 10 miles per hour. A STOP sign is not a ''.cure-all" and is not a substi• tute Cor other traffic control devices. Many times the need for a STOP sign can be eliminated if the sight distance is increased by removing obstructions. The installation of STOP signs at locatiom where they are unexpected or where approach speeds are __ high should be avoided if possible because they may·· increase accidents. However, if there is no alterna• tive to a S"T'OP sign, then an advance Code Wl7 STOP AHEAD sign and appropriate pavement markings should be placed in conjunction with iL Publicity through the radio and press is highly de- sirable when SI'OP signs are installed and especially when it is necessary to change their location. Any of the following conditiom may warrant a four-way stop sign installation: 1. Where traffic sipws are warranted and the need is urgent, the four-way stop is an interim measure that can be installed quickly to control traffic while arrangements are being made for the signal installation. 2. An accident problem, as indicated by five or more reported accidents of a type susceptible of correction by a four-way stop installation in a 12-month period. Types or accidents susceptible of co~ection include right angle and left tum collisaom. 3. Minimum volume warrant: L The· total vehicular volume entering the in- tersection from ~ approaches must average at leut 500 vehicles per hour for any eight hours of an ave~ge day, and b. The combined vehicular and pedestrian vol- ume from the minor street or highway must average at least 200 units per. hour for the same eight hours with an average delay to minor street vehicular traffic of at least 30 seconds per vehicle during the maximum hour. - c. When the 85-percentile approach speed of the major street traffic ezceeds -40 miles per . hour, the minimum vehicular volume war- rant is 70 percent of the above requirements. A (our-way stop sign installation is a useful traffic control measure when other available meam of con• trol are not adequate. It should not be used unless the volume of traffic on the intersecting roads is about equal and is undesirable at low-volume intersectiom. When STOP signs are placed on all entertng legs of an intersection, each !ITOP sign may be supple- mented by a separate plate mounted below it with the message "~WAY", "4--WAY", etc. The supple- mental plate shall have white letters on a red back- iiround. The 18"x18" size is for use onlv on bicvcle trails where bicyclists are required to stop. If the sign applies to motorists and bicyclists. the standard size stop sign shall be used. The bike 18"x18" size has been added. The sign fonnat ha.s been changed to agree with the federal fonnat Please note the minor change in border width Cor the 2,l", JO", 36" and 48" sizes.
