BACKGROUND: At their last meeting, the Redevelopment Agency requested information regarding the possible relocation of the bollards along the E1Camino Real project to provide a minimum clear distance of 40 inches between bollards. DISCUSSION: Staff has reviewed the bollards at each of the intersections and found the narrowest width between the two center bollards to be as shown on the attached sketch. It has been suggested that one of the two center bollards be relocated to provide a clear distance of 40 inches. It is assumed that this clear distance of 40 inches is measured at the base at ground level which would result in relocating one bollard at each corner a distance of 3 inches or less. If only one bollard at each corner were relocated, the spacing would be non-symmetrical and could result in a displeasing visual effect. As of the writing of this memo, the contractor has relocated all of the bollards that were not installed to the minimum required clear distance. In my previous memo, it was indicated that Section 3303e of the Uniform Building Code provides that the clear width of an exitway shall not be less than 32 inches for handicapped purposes. It is assumed that this dimension is based upon a width that would be utilized by the majority of handicapped individuals. The clear width between bollards where an individuals hands would be located is 40 3/4 inches, as shown on the attached sketch. Staff has estimated the cost of relocating the bollards as follows: Unlighted Bollards . . . $650/unit x 19 units : $12,350 Lighted Bollards .... $900/unit x 4 units = 3,600 TOTAL ESTIMATED COST $15,950 EL CAMINO REAL BOLLARDS JANUARY 21, 1983 PAGE TWO It is staff's recommendation that the bollards not be relocated to a clear distance of 40 inches between the two center bollards at each corner because they now exceed the required minimum clear distance of 32 inches as specified in the Uniform Building Code by 5 inches. BOB LEDENDECKER DIRECTOR OF PUBLIC WORKS/ CITY ENGINEER db Attachment I DATE: NOVEMBER 9, 1982 Inter-Corn TO: FROM: S UBJ ECT: WILLIAM HUSTON, EXECUTIVE DIRECTOR TUSTIN COMMUNITY REDEVELOPMENT AGENCY BOB LEDENDECKER, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER EL CAMINO REAL/MAIN STREET BOLLARDS (INFORMATIONAL REPORT) At the request of Mayor Edgar, the following information has been assembled to clarify the bollard installations at the various corners along E1Camino Real and Main Street. It is requested that this report be distributed to the Redevelopment Agency for their information. The plans call for bollards to be placed on 4'-0" center to center. The widest dimension (diameter) of each bollard is 0'-10 3/4" measured at the base or at ground level. Consequently, the clear dimension between bollards should be 3'-1 3/4" or 37 3/4". The bollards., as placed in the field, range between 37" and 39" clear dimension between bases. Section 3303e of the Uniform Building Code provides that the clear width of an exitway shall not be less than 32" for handicapped purposes. The placement of these bollards installed to date exceed the minimum required width of clearance by 5" as measured at the base of the bollard.' db
