LM SA? �2 14 V N k + e q��FORN�P City Council Staff Report CITY COUNCIL OCTOBER 5, 2005 CONSENT CALENDAR Subject: APPROVAL OF AMENDMENT NO. 4 TO THE CONTRACT SERVICES AGREEMENT WITH DMC DESIGN GROUP, INC.; AND APPROVAL OF PLANS, SPECIFICATIONS AND ESTIMATE (PS&E) AND AUTHORIZATION TO BID FOR "PHASE V OF THE MESQUITE AVENUE WIDENING PROJECT, CITY PROJECT 94-17 From: David H. Ready, City Manager Initiated by: Public Works and Engineering Department SUMMARY Street, storm drain, and landscaping improvement plans for the Mesquite Avenue Widening Project (City Project 94-17) have been processed by City staff through an exhaustive process with Riverside County Flood Control District (RCFC). While the street and landscaping improvement plans are fairly straight forward, the storm drain improvement plans have been a challenge to prepare, having to avoid the numerous sewer lines that end at the Wastewater Treatment Plant, as well as circumnavigate the Wastewater Treatment Plant itself. The construction documents (Plans, Specifications and Estimate) are completed and, in accordance with 7.03.040 of the Procurement and Contracting Code the Council is required to approve and adopt plans, specifications and working details, and authorize the bid request for all public projects in excess of $100,000. Approval of this project will allow staff to proceed with this public project, with an estimated cost of approximately $1,700,000. :staff, in consultation with RCFC and the City's design consultant, DMC Design Group, Inc., have agreed that the storm drain improvement plans for Storm Drain Line 22 (through the Wastewater Treatment Plant) should be phased, such that Line 22 can be extended to locate the outlet at a different point in the Tahquitz Creek than originally planned, and to accommodate other concerns that RCFC has had with its original design. Therefore, it is also necessary for City Council to consider approval of a fourth amendment to the contract services agreement with DMC Design Group, Inc., for services required to phase the design of Line 22 and to resolve remaining issues with the storm drain improvement plans in order to receive final RCFC approval of "Phase 2" of Storm Drain Line 22. In this way, staff can proceed and build "Phase 1" of the Item No. 2 . K . City Council Staff Report October 5, 2005 - Page 2 Mesquite Avenue Widening (CP 94-17) Mesquite Avenue Widening Project now, and complete the "Phase 2" design during the construction of "Phase 1". RECOMMENDATION: 1) Adopt Minute Order No. , approving Amendment No. 4 to Agreement No. 4724 with DMC Design Group, Inc., for an additional amount of $30,750.00, for a total contract price of $174,625.00; and 2) Adopt Minute Order No. , approving the plans, specifications and working details for "Phase 1" of the Mesquite Avenue Widening Project, CP 94-17, and authorizing staff to advertise and solicit bids. 3) Authorize the City Manager to execute all necessary documents. STAFF ANALYSIS: The Mesquite Avenue Widening Project (City Project 94-17) has been a project the Engineering Division has been working on for many years. Originally, it was Engineering staff's intent to prepare street improvement plans for widening of Mesquite Avenue within the Demuth Park area (Mountain View Drive to Vella Road) in accordance with the General Plan as a Secondary Thoroughfare (64 feet travel way with 2 lanes in each direction and a parking lane on each side). Funds were originally budgeted for this project in the 2000/2001 fiscal budget. It has been staffs goal to address the poor pavement condition of Mesquite Avenue at the same time as the widening of the roadway occurred, to avoid misspent funds for permanent repairs that might conflict with the overall widening and pavement overlay of the roadway. Another goal has been to remove the "dips" that exist along Mesquite Avenue, which are due to the numerous cross-gutters that convey stormwater runoff through the :streets in the adjacent neighborhood, which eventually drains into Demuth Park (through the parking lot), or down Vella Road into the Wastewater Treatment Plant. It is the constant nuisance water that drains onto Mesquite Avenue from the entire area up to Ramon Road that has caused the pavement condition on Mesquite Avenue to deteriorate; and it was determined that any widening, repair or improvement to Mesquite Avenue could only occur with associated storm drain improvements that would collect and convey the constant nuisance water from the adjacent neighborhood such that continued deterioration of the pavement would not occur. Before staff could begin to prepare plans for the Mesquite Avenue improvements, staff was made aware of concerns from the adjacent neighborhood regarding the volume and speed of "cut-through" traffic along Mesquite Avenue, which has increased after the construction of the Dinah Shore bridge and the opening of the "Mid Valley Parkway". Staff did review this concern, and it was determined that an increased volume of traffic was using Mesquite Avenue as a bypass route to avoid the signalized intersections City Council Staff Report October 5, 2005- Page 3 Mesquite Avenue Widening (CP 94-17) along Ramon Road. In determining the need to address the cut-through traffic, Engineering and Planning staff began to collaborate together on a plan for Mesquite Avenue to address the need to complete repairs and make improvements to the street, as well as mitigate the increased volume of traffic as a result of the opening of the Dinah Shore bridge and completion of the Mid Valley Parkway. Ultimately, the final conceptual plan for improving Mesquite Avenue required lengthy review by various parties, including the Parks & Recreation Commission, Planning Commission, and City Council. From the very beginning of staff's discussion with the neighborhood, it was consistently requested that Mesquite Avenue be modified to limit traffic to one lane in each direction. However, Mesquite Avenue was designated as a Secondary Thoroughfare on the General Plan, requiring two lanes in each direction. The Engineering Division's initial concern with changing the classification of Mesquite Avenue was with regard to the average daily traffic (ADT) of over 10,000 cars that use Mesquite Avenue. A two-lane facility can sufficiently carry this volume, however, in the future as traffic volumes were expected to increase, the level of service of Mesquite Avenue, limited to one lane in each direction, would be expected to decrease. Staff prepared various alternative conceptual designs with two lanes of traffic (one in each direction) for Mesquite Avenue adjacent to Demuth Park. These various plans were presented at numerous public meetings, beginning with a Planning Commission Study Session on June 6, 2001; and subsequent Planning Commission Study Sessions on February 6, 2002; May 1, 2002; and July 17, 2002. A presentation was also made to the Parks & Recreation Commission on September 18, 2002. At each meeting, public input was received and the conceptual plan revised and modified. The City Council was first presented with alternatives for Mesquite Avenue at its September 25, 2002, Study Session, followed by one held on November 13, 2002. The City Council was originally concerned with a classification change of Mesquite Avenue and a limitation of one lane of traffic in each direction, which required additional coordination with the neighborhood, as well as further review by the Planning Commission. Staff reviewed other conceptual plans with the Planning Commission at its January 15, 2003, Study Session. Despite the City Council's concern, the neighborhood's overriding criticism of the volume of "cut-through" traffic and traffic speeding on Mesquite Avenue persuaded the Planning Commission to continue its support of a two-lane facility and a classification change for Mesquite Avenue. A final version of the conceptual plan was reviewed and approved by the City Council at its January 22, 2003, Study Session. The final conceptual plan approved for Mesquite Avenue in the Demuth Park area will create one lane for east-bound and west-bound through traffic, with a one-way (east- bound) lane with parallel parking adjacent to Demuth Park separated from the through traffic lanes by a 12 feet wide landscaped median. Access to the existing single family homes along Mesquite Avenue will not be changed or limited by this project, and will continue to have unrestricted access from their driveways and parking adjacent to curb. City Council Staff Report October 5, 2005 - Page 4 Mesquite Avenue Widening (CP 94-17) The one-way lane with parallel parking will connect the two Demuth Park parking lots, separating the local park traffic from through traffic on Mesquite Avenue. The landscaped island will also help provide additional safety for pedestrians and park users by creating a buffer between the through traffic and Demuth Park. Other improvements will revise the intersection of the main parking lot entrances with Nueva Vista Drive, install traffic calming improvements (chokers, decorative cross-walks, etc.), create a west-bound free-right turn movement at Vella Road, as well as install storm drainage improvements to remove all the existing cross-gutters and "dip" sections along Mesquite ,Avenue. Finally, a 4-way stop will be proposed at Mountain View Drive, Nueva Vista Drive, with one already having been installed at Vella Road. Engineering staff prepared a Request for Proposals for the necessary design services in March 2003, and on June 18, 2003, a contract services agreement was awarded to DMC Design Group, Inc., to prepare the street, storm drain, and landscaping plans to construct the proposed Mesquite Avenue improvements. Subseqently, on December 17, 2003, City Council approved Case 5.0965, which allowed an amendment to the General Plan Circulation Element to designate Mesquite Avenue within the Demuth Park area as a "Special Collector", which formally endorsed the conceptual plan for Mesquite Avenue. Since that time, staff has been working diligently with its consultant to prepare the construction documents for this project. While the street and landscaping improvement plans are fairly straight forward, the storm drain improvement plans have been a challenge to prepare, having to avoid the numerous sewer lines that end at the Wastewater Treatment Plant, as well as circumnavigate the Wastewater Treatment Plant itself. Further, the storm drain improvement plans have been processed through Riverside County Flood Control District (RCFC) for review and approval, as RCFC will ultimately operate and maintain the proposed storm drain lines. RCFC has rather strict design guidelines, and their guidelines have represented a serious challenge for design of the proposed storm drain through the Wastewater Treatment Plant, and ultimately, outletting into the Tahquitz Creek wash in an area that does not disrupt the Tahquitz Creek golf course. Despite staff's consistent pressure on RCFC staff, as well as the design consultant, some design issues have not yet been resolved, and have ultimately continued to delay staff's delivery of this project. In a final meeting with RCFC staff and the design consultant, it was determined that the design and construction of Storm Drain Line 22 (which runs through the Wastewater Treatment Plant) would be phased into two separate projects, allowing the City to proceed with the Mesquite Avenue Widening Project and installation of the necessary storm drain improvements within Mesquite Avenue. The City's design consultant will continue to coordinate with RCFC on "Phase 2" of the design of Line 22, which will ultimately be extended south to an outlet located immediately upstream of the Gene Autry Trail bridge. City Council Staff Report October 5, 2005- Page 5 Mesquite Avenue Widening (CP 94-17) Therefore, it is staff's intent to move forward with "Phase 1" of this project, which will construct all of the Mesquite Avenue improvements, including all of the portion of Storm Drain Line 21 which will collect and convey stormwater runoff through underground storm drain pipe into Demuth Park (rather than by surface drainage through the parking lot). Ultimately, in the future, the storm drain pipe will be extended to connect with Storm Drain Line 22, and periodic flooding of the recreation areas within Demuth Park will not occur. "Phase 1" will also construct a portion of Storm Drain Line 22, ending at a point just inside the Wastewater Treatment Plant, where currently stormwater runoff drains into an unused percolation pond. (Phasing of the storm drain improvement plans, designing the extension of Line 22, and continued coordination with RCFC to address remaining issues requires additional services beyond the scope of the design consultant's original contract. In addition to approving the "Phase V plans, with an authorization to bid, staff is recommending the proposed amendment to the design consultant's contract. Approval of the recommended actions will allow staff to proceed with bidding of this project, with a tentative bid opening date of Friday, November 18, and an award date of December 7, 2005. FISCAL IMPACT: Finance Director Review: Sufficient funds are available in Central Zone Drainage fund ad`count 135-4371-55008 (Storm Drain Line 22) to fund the proposed contract amendment increase of $30,750. The City Council's approval of the plans, specifications and working details for the Mesquite Avenue Widening Project, CP 94-17, and authorizing staff to advertise and solicit bids does not incur significant expense except those costs directly related to bidding the project. Sufficient funds have been budgeted in the Central Zone Drainage fund account 135-4371-55008 (Storm Drain Line 22), Gas Tax accounts 133-4298- 150177 (Mesquite/Desert Way) and 133-4298-50194 (Mesquite Ave Widen/South), and Local Measure A accounts 134-4498-50177 (Mesquite/Desert Way) and 134-4498- 50194 (Mesquite Ave Widen/South) to cover the Engineer's estimated cost for "Phase 1" of this project.
