Approve the use of Scarlett Court as a temporary off ramp which will require the elimination of parking on Scarlett Court provided that: a) none of the associated costs will be paid by the City of Dublin. b) a temporary City parking lot is constructed to replace lost on- street parking (approximately 22 spaces). c) adequate traffic control measures are taken to safely handle the revised traffic configuration. FINANCIAL STATEMENT: No construction cost to City; some staff time for review and monitoring will be incurred; some possible liability exposure from the use of the temporary City parking lot. DESCRIPTION: At the January 28, 1985 City Council meeting, Bissell & Karn, Inc. presented a progress report on the Hopyard Road/Dougherty Road/I-580 Interchange Improvements. At that time they discussed briefly the staging for the Construction and Maintenance of Traffic Plans of the interchange improvements. Bissell & Karn recommended using Scarlett Court during two different construction stages. The first stage where the use of Scarlett Court is required involves the construction of the retaining wall between the westbound off-ramp and Scarlett Court. This construction would require removing the parking in the area immediately adjacent to the retaining wall where the off-ramp abuts Scarlett Court, and shifting the traffic lanes to the north side of the street. This condition would be in affect for 1 to 2 months. It is important to receive Council concurrence on use of Scarlett Court in this construction stage. This phase is expected to occur in the months of July and August. This will require the removal of parking on Scarlett Court, however, the areas involved with this stage are not usually utilized for parking. COPIES TO: Bissel & Karn TJKM It is proposed that a temporary off-ramp be constructed that would detour westbound off-ramp traffic onto Scarlett Court (see attached exhibit). This detour would be used, for approximately 2 to 3 months (currently anticipated to begin in August). Presently 1,000 vehicles use the existing westbound off-ramp during the peak hour and would subsequently use the temporary off-ramp. A conservative estimate of the percentage of trucks is 10 percent. There are many benefits of using Scarlett Court as a detour for westbound off-ramp traffic. The main benefit is that the use of the detour prevents traffic from traveling through the construction zone which results in a safer condition. This temporary ramp will make Dublin Boulevard more accessible. The motorist will reach Dublin Boulevard by a through movement at the Dublin/Dougherty intersection, rather than the existing difficult right-turn and left-turn movements. Also, this condition will benefit those motorists exiting the freeway and traveling south towards Pleasanton. These motorists presently wait for a gap in Dougherty Road traffic in order to make a left turn from a stop sign. The detour will allow this left turn to be made at the signalized Dublin/Dougherty intersection. This temporary ramp would have 2-lanes and would intersect with Scarlett Court at an approximately 60 degree angle near the Lew Doty Cadillac property. The lane arrangement of the temporary ramp would be an exclusive left-turn lane and a shared lane for left and right turns. The intersection of Scarlett Court and the temporary ramp would be controlled by stop signs on all approaches. As presented at the previous City Council meeting, a number of changes on Scarlett Court will be required. The on- street parking on Scarlett Court west of the new intersection would be temporarily eliminated. Scariett Court would be restriped to have 2 lanes westbound and a single lane eastbound. At the intersection of Scarlett Court and Dougherty Road, both the narrow center median island on Scarlett Court and channelizing island in the northeast quadrant of the intersection will be removed. Scarlett Court would then be restriped near the intersection to accommodate 3 approach lanes. The traffic signal would also require retiming. The level-of-service for the Scarlett Court/Dublin Boulevard/Doughterty Road intersection would be the same as exists today after these improvements are made. Representatives of some of the impacted businesses had expressed concerns related to removing the on-street parking. A possible solution to this problem is a temporary parking lot./ There is room available for a 22 vehicle lot in the interchange right-of-way south of the existing buildings on the south side of Scarlett Court. This lot would be accessed from Scarlett Court. Both Caltrans and the Federal Highway Administration (FHWA) have reviewed and given tentative approval to the use of the highway right-of-way for a temporary parking lot. The only FHWA condition is that the parking lot be temporary and not permanent. Caltran's main concern with the parking lot was that they not be held liable for any accidents. Given the establishment of a temporary public parking lot, it would be the City of Dublin who would be assuming the responsibility as it would for a municipally owned parking lot. It is suggested that the temporary lot be used by the businesses primarily for employees, freeing the existing private parking for customers. It is also recommended that the merchants cooperate among themselves to share any available parking. TJKM studies have indicated a maximum on-street parking usage of 25 stalls along Scarlett Court. Therefore, a 22 stall lot should alleviate most parking problems. If Scarlett Court is not available to use as a detour, the only alternative is to direct traffic through the construction zone. The free right-turn movement into Dublin would be eliminated. Both the right and left turning ramp traffic would be controlled at Dougherty Road by a stop sign. The left turn movement into Pleasanton will become more difficult under this scenario. It is important that these matters be resolved immediately so that the schedule for the improvements will not be affected. All costs related to the construction of this interchange will be paid by developers in North Pleasanton through a City of Pleasanton assessment district. Notices of the City Council meeting have been provided to adjacent businesses. It is recommended that the City of Dublin take responsibility for the temporary parking lot as a municipal parking lot independent of any construction and design defects and confirm this in a letter to Caltrans (see attached draft). Also, the City Council should allow the use of Scarlett Court as a construction detour and provide for the necessary no parking restrictions. 1-580 P.O.

Box 7310 San Francisco, CA 94120 Attention: Robert L. Cashion, District Permit Engineer Subject: 04-Ala-580, 19.8/20.0 Hopyard Road interchange Gentlemen: I wish to inform you that the City of Dublin will assume responsibility of the temporary parking lot to be constructed in conjunction with the Hopyard Road/Dougherty Road/I-580 Interchange Improvements. This assumption of liability shall be subject to the contractor being held responsible for defects in construction and design. The temporary parking lot (see attached exhibit) is on State of California right-of-way, however, it would be accessed from Scarlett Court. The temporary parking lot is required with the proposal to utilize Scarlett Court as a detour for the westbound off-ramp traffic. Scarlett Court will be converted to 2-lanes for westbound traffic and 1 lane for eastbound traffic. This requires elimination of on-street parking during this stage of construction. Businesses in the area have voiced concern that removal of the on-street .parking would be detrimental. The temporary parking lot can accommodate approximately 22 vehicles which would alleviate the parking problems. We wish to resolve this matter as quickly as possible and request a response from Cal~rans in writing that the arrangement concerning the temporary parking lot is acceptable. If you have any questions or comments, please do not hesitate to telephone. Sincerely, RCA/cf cc: Steve Lee Leo Davies Richard C.
