Interchange Engineering Services (General Plan)CITYOF AGENDA ITEM NO: 8 SAN R.AFAEL MEETING DATE: July 19, 1993 Department of Public Works REPORT TO MAYOR AND CITY COUNCIL SUBJECT: RESOLUTION ACCEPTING PROPOSAL FROM CH2M HILL FOR PHASE II OF THE ENGINEERING SERVICES FOR FREITAS INTERCHANGE IMPROVEMENTS AND APPR 4ire PROJECT AS BEING CONSISTENT WITH THE GENERAL PLAN SUBMITTED BY: APPROVED BY: or of tic Works (A 1') City anager FILE REF: 05.01.43.01 07.02.32.01 RECOMMENDATION: I recommend that the Council adopt the Resolution: 1. approving Public Project's Consistency with the General Plan; 2. accepting the proposal from CH2M Hill for preliminary engineering and final design services for the Freitas Parkway Interchange Improvements. 3. directing staff to prepare a cooperative agreement with the County of Marin Right of Way Services for property acquisition. SUMMARY/BACKGROUND: On March 1, 1993, the Council accepted a proposal from CH2M Hill for the initial analysis and preliminary design of a proposed single point interchange at the intersections of Freitas Parkway, Redwood Highway, Civic Center Drive and Highway 101 off -ramp (known as the Freitas Parkway Interchange). Due to the complexity of the proposed interchange, traffic forecasts and geometries, it was not known at that time if the proposed solution would work. The preliminary analysis and geometric layout have been completed by CH2M Hill and submitted to Caltrans for review. A thorough review of the traffic analysis and preliminary layout has been performed by Caltrans and conceptual approval has been given to the traffic study report and intersection geometries. On June 13, 1993, a report was presented to the Planning Commission (see attached report) that outlined the design concept and project consistency with the General Plan. The project was strongly supported by the North San Rafael Coalition and the design concept was approved by the Planning Commission. The Commission also recommended that the Council approve Public Project Consistency with the General Plan. File No. ----- lt1J.-.', Co incil vieetiog ID vosi ion This project is being primarily funded through ISTEA funds in the amount of $1.1 million, and the remainder from traffic mitigation fees. In order to comply with ISTEA funding guidelines, the project must be designed and out to bid by September 1994. This very tight timetable must be adhered to or the funding will be lost. CH2M Hill have completed the initial phase of this project and are now ready to commence the preliminary engineering and final design. They have submitted a proposal for this work (Attachment "A") in the amount of $188,800.00 Staff have reviewed this proposal and find it to be complete and within industry standards. I recommend that the Council accept the proposal and authorize the Director of Public Works to amend the agreement with CH2M Hill. In order for the City to comply with Federal guidelines, all property acquisition for the project must be performed by a State certified Right of Way agent. Property will need to be obtained for the new retaining wall on Redwood Highway (owned by the Campbell Estate) and a small sliver of land may be required on the east side of Civic Center Drive. Staff have met with staff from the County of Marin Right of Way Services Department and outlined the services that would be required. The County of Marin indicated that they would be willing to perform this work on behalf of the City. If the Council is receptive to this arrangement, staff will prepare a cooperative agreement with the County and will bring it back to the Council for execution at a later date. ENCLOSURES: (4) 1.

I �' f CITY OF SAN RAFAEL SAN RAFAEL, CALIFORNIA INTER -DEPARTMENTAL MEMORANDUM DATE: July 14, 1993 TO: Mayor and City Council FROM: Planning Department SUBJECT: Freitas Parkway Interchange Signalization Improvements Attached is the Planning Commission report on the Freitas Parkway Interchange Signalization Improvements. The Planning Commission reviewed the design concept on July 13. They unanimously approved the design concept and recommended Council approval of this public project as being consistent with the General Plan. They stated a preference for a final design which includes large, fast growing street trees along Redwood Highway if at all possible, and supported inclusion of measures to discourage graffiti on the proposed retaining wall, such as vines. Area neighborhood organizations, nearby businesses and property owners were notified of the Commission's review. Sue Beittel, Shirley Fischer and Carole Dillon spoke in favor of the proposal. They stated there is strong community support to signalize and improve this interchange and thanked the City for pursuing this project. Fischer stated the North San Rafael Coalition believes the proposed design is a good one. She noted the Coalition still has some concern about the possibility of offramp traffic backing up on 101, but recognize that Caltrans has found the proposed multi -lane storage to be acceptable.

These include a new Merrydale freeway overcrossing from Northgate Drive to Civic Center Drive, a new northbound freeway onramp from Redwood Drive north of Freitas, and related Freitas intersection signalization improvements. The Merrydale Overcrossing and northbound .ramp project is fully approved. This project provides additional capacity for all planned area development. It is expected to go out to bid for construction later this year. This report discusses the related signalization and redesign of the Freitas/101/Civic Center Drive intersection. The intersection will be redesigned to operate as one standard intersection and will eliminate the difficult left turn to the existing northbound ramp. The redesign will improve operation of the intersection. The project is consistent with the General Plan; it is an Plan implementing measure. It will meet City level of service standards now and in the future. This concept design review provides early information to nearby and interested residents and businesses about the project. Traffic impacts of the related Merrydale/northbound ramps proposal are covered in the prior General Plan EIR. This signalization project is Categorically Exempt per Section 15301 (c) of CEQA Guidelines. itlrl"Vl�1 1V rL. NLN L1V" l.lJ1V11V11J011J1V11"aYC L i'l...-. 1V V.. 17✓Z BACKGROUND-, Existing Intersection The existing unsignalized Freitas/101/Civic Center intersection has an unusual "H" design and is confusing to use. See Figure 1. During review of the approved Merrydaie Overcrossing project, residents urged signalization and improved design of the Freitas/101/Civic Center intersection. The City Council agreed and directed staff to include the signalization/redesign as a second phase to the overcrossing project. The City then sought and received ISTEA funds to accomplish the redesign. Proposed Design The Department of Public Works (DPW) selected CH2M Hill as its consultant on the Freitas project. DPW staff and the consultant have concluded that the intersection would function more smoothly and safely if it is altered into a more standard single point intersection. See Figure 2. The proposed intersection lines up Civic Center Drive and Freitas as one axis and the 101 northbound offramp and Redwood Parkway as the other axis. (The one way drive to the Northgate East office buildings would remain.) To accommodate signalization and keep traffic from backing onto the freeway, the northbound offramp will be widened to 3 lanes. The existing movement from Civic Center/Redwood to the existing northbound 101 onramp will be eliminated with the construction of the approved new northbound onramp- - to be constructed approximately 400 feet north of this intersection. To line up the intersection and provide adequate turning radii, Redwood Highway must be widened from the intersection of Civic Center and Freitas Parkway to approximately 300' north. The widening would cut into the hillside approximately 20-25 feet, and require a retaining wall. Several retaining wall alternatives were considered. An alternative without street trees would range from 5 to 15 feet, and average 7-8 feet in height. This alternative is shown in the photo montages included as Attachment A. Street trees planted in front of the wall would push the wall back 4-5 feet and consequently increase the height of the wall about 5 feet. to from 5 to 20 feet high. Visual impacts of this alternative are shown in Attachment B. A third stepped wall alternative was preliminarily developed and discussed at the Design Review Board meeting. A medium brown, rough textured wall finish would be used to blend with the hillside. Minor additional right of way will be needed at the wall location, but exact amounts will not be known until final design; the affected hillside is part of a fully developed parcel. Design Review The intersection design concept was reviewed by the City's Design Review Board on May 19, 1993. The Board focused on landscaping and the retaining wall alternatives. They agreed that a wall texture similar to either the 101 soundwall or the Point San Pedro would be acceptable. They recommended there be no smooth concrete "cap" along the top of the wall (as shown in the Attachment A photos). They suggested a slightly undulating or jagged top edge to better blend with the hill. They preferred the alternative with street trees and a higher height, noting that the intersection is a 2 FILE NO.: P93-4 REPORT TO ^LANNING COMMISSION/Pace 3, major entrance to the City, and trees would help soften it. Landscaping at street level was preferred to vines from the top of the wall due to concerns about drainage behind the wall. While they considered a stepped retaining wall alternative, they agreed this would be more intrusive, introducing more unnatural elements higher on the hillside. The lower wall alternative, and the wall with trees in front will be carried through to the final design stage; if costs for either are not prohibitive, either alternative could be selected at that time. Staff suggests that if the higher wall alternative is cost prohibitive, a wall with a narrow (1-2' wide) planter strip adjacent to it be considered with vines or bushes. This alternative could combine the benefits of the lower wall height with some vegetation to help soften the wall. The Board recommended that the wall treatment and landscape plans be brought back to them at the final design stage. In addition, they urged CH2M Hill to work with Caltrans and increase landscaping elsewhere in the intersection as part of the project. Overall Process and Timing Currently, the project is in the preliminary design stage and is awaiting approval from Caltrans (the permitting agency) to proceed to the final design stage. Caltrans has reviewed and tentatively approved the proposed design; formal approval is anticipated within two weeks. The City has a tight schedule to design and award the contract by October, 1994, according to ISTEA guidelines. The Federal monies are capped at a maximum with any overrun to be paid for by the City. The project is scheduled to be under construction in early 1995. Once actual construction timing and phasing are known, staff will provide information to nearby businesses and residents. The Merrydale Overcrossing and ramp project is expected to precede this project. Given its lengthy planning history, if, for some unforeseen reason, the overcrossing and ramp project was not underway by the time this signalization project begins, the northbound ramp portion would need to be constructed in conjunction with this project. Traffic Analysis The 1985 Highway Capacity Manual procedures for operations were used to determine level of service (LOS) - These methods are used (instead of planning level analysis) at the design stage to better reflect specific intersection design requirements such as left turn storage. The traffic operational analysis of existing and future traffic conditions was based on actual and forecasted turning movements. Actual conditions were counted in May, 1993. Forecasts are based on build -out projects from the General Plan, as updated in the 1991 Northgate Assign Model Update. The Freitas intersection signalization and redesign project was originally conceived to retain the "H" configuration. Consultant review strongly recommended the single intersection design. Because the intersection configuration is different from the Northgate report, the consultant had to modify turning movements. However, the total approach volumes are the same as the overall transportation system and land use assumptions in the General Plan and Northgate report. 4 i(�rVn i i V i'LA1V 1V llVl� I.VMMI�JIVIV / Page 4 MUM IVU.. r7o-4 Results of this analysis conclude that the intersection will operate better than the City's mid LOS D standard (Volume/Capacity: V/C 0.85) now and in the future. Future buildout V/C ratios are projected to be 0.77 during the PM peak, and 0.78 during the AM peak. The operational analysis includes both volume capacity ratios and delay. Using this methodology, the level of service corresponds to a .80-.82 V/C, or above mid D. The intersection will operate even better in the near term. See Attachment C for Buildout Forecast traffic volumes and supporting traffic data. This information will be appended to the 1991 Northgate Update report.

Freitas Parkway/U.S. 101 Interchange Traffic Study Report, the November 1991 San Rafael Northgate Assign Model update is modified to reflect intersection signalization refinements. The following updates are localized to the Freitas/northbound off-ramp/Civic Center/Redwood intersection. They are consistent with the City's General Plan land use assumptions, maintain upstream and downstream traffic flow continuity, and do not require further analysis of the system network. Charts 6A and 7A, pages 17 and 19 are replaced with the following charts to reflect the redesign to a single Freitas Parkway/101/Civic Center/Redwood intersection. The descriptions of #10 and #11, pages 26 and 27 are also amended as follows: "10 and 11. Manuel T. Freitas Parkway/U.S. 101 northbound ramp and Redwood Parkway/Civic Center Drive intersections. As a result of the Merrydale Overcrossing and Highway 101 Northbound on-ramp project, the existing two intersections would be signalized. These intersections will be realigned into one intersection, and movements from Redwood Parkway and Civic Center Drive will be relocated just north of the existing U.S. 101 northbound access. This project includes signalization, the addition of a left -turn lane to the Manuel T. Freitas Parkway approach, right -turn lane to Civic Center Drive, and left -turn lane to Redwood Highway. Without the proposed improvements, the two intersections would operate at LOS D (V/C 0.88) and experience delays due to close spacing under build -out conditions during the p.m. peak hour. With the proposed improvements, the intersection will operate at a V/C = 0.77, above the City's mid -LOS D standard. Proposed improvements are estimated to cost $1.4 million." In addition, the first paragraph, p. 24 is replaced with the following: "The intersection of Manuel T. Freitas Parkway/Highway 101 northbound ramp and Redwood Highway/Civic Center Drive intersections are Phase II to the Merrydale Overcrossing project. This signalization project was recommended as part of the Merrydale project approval. The original project has been redesigned to include consolidation of the U.S. 101 ramp intersection and Redwood Highway/Civic Center intersection into one intersection. Because the project includes restriction of access to northbound U.S. 101 from Redwood Highway and Civic Center Drive, northbound U.S. 101 access from Redwood Highway north of this intersection must be completed prior to construction of this project." 257 (205) -- * 319 (160) —0 1248 (804) ---X co 3 s v O O 3 Lo d r co N NT W N co 'q:t M N r` W-- 291 (641) 4 55 (266) Ar-- 0 err T- O N C0 l0 co Cn v M Co Co CO 'IT N "Cr m Civic Center Drive M C a. o� M L � Legend oQ Z xxx am peak hour (xxx ) pm peak hour TRAFFIC VOLUMES FORECAST (YEAR 2015) C�.�r!'HILL SF035474 Al 02 1985 HCM: SIGNALIZED INTERSECTIONS SUMMARY REPORT INTERSECTION..Freitas Parkway/US-101 NB Off-ramp AREA TYPE .....

Box 151560 San Rafael, CA 94915-1560 Dear Mayor Boro and Council Members: The Steering Committee of the North San Rafael Coalition would like to give support to the Freitas Interchange Signalization Improvements which were approved in concept by the Planning Commission on July 13th. We urge you to approve final design of this project so that it can proceed in a timely manner. We would like to express our appreciation for the City's responsiveness to community concerns regarding hazardous conditions at the Freitas northbound interchange and frontage roads. Reconfiguration of the intersection from an "H" to a single -point "X" intersection will, we believe, eliminate much of the confusion and crossing traffic flows which currently make this such a dangerous intersection. This configuration will also permit more accurate future traffic analysis of this compldx interchange as a single intersection. We reconunend that CH2M Hill's methodology of using both delay analysis (1985 Highway Capacity Manual) and volume/capacity ratios (Circular 212) to determine traffic level of service be continued, since LOS calculation based solely on volume/capacity ratios may not accurately reflect traffic conditions at this complex intersection. We also request that holding lanes on off -ramp (and on Freitas Parkway) be maximized, since there is continuing concern in the community that there is not sufficient space to accomodate waiting traffic without backup onto Highway 101 (and Freitas Parkway). Finally, we would like to express appreciation to City staff who have welcomed community input in the design of �+ �+TTy this project. 1.
