Kennedy called the meeting to order at 3:30 p.m. Al. Roll Call: Present were Mayor Pro Tern Lynne B. Kennedy and Council Member Ryan A. Hutchison Staff present: John R. Gillison, City Manager; Lori Sassoon, Deputy City Manager, Administrative Services; Jason C. Welday, Engineering Services Director/City Engineer; Gianfranco Laurie, Senior Civil Engineer; Albert Espinoza, Deputy Public Works Director; Dean Rodia, Parks and Landscape Superintendent; and Valerie Victorino, Executive Assistant II. Public present: Larry Henderson, Liaison, Alta Loma Riding Club. B1. Larry Henderson spoke under Public Communications regarding the erosion damage on the Randolph Davis Property Community Trail and the bridges at Heritage Park. Mr. Henderson expressed concerns with the timing on the erosion damage and the potential loss of access to and from the equestrian center at Heritage Park if the westerly bridges were removed and the three bridges at the center entrance were combined into a single bridge. In response to Mr. Henderson's concerns, staff provided information to the Sub -Committee on the anticipated schedule for the trail repair and potential access points for the equestrian center. Cl. Approve and File Minutes of September 18, 2019. Motion by Council Member Hutchison, seconded by Mayor Pro Tern Kennedy to approve the minutes. Motion approved. C2. Update on the Randolph Davis Property Community Trail and Heritage Park Bridges. A staff report was presented by Senior Civil Engineer Laurie providing an update on the status of the needed repair of erosion damage to to the Randolph Davis Property Community Trail caused by heavy storm events this past winter. The trail has been temporarily closed and estimates for repair and reconstruction range from $360,000 for short-term repairs to $640,000 for long-term improvements to minimize potential for future erosion damage. Further, the City has submitted an insurance claim seeking to recuperate up to $500,000 in costs for the repairs but have not received a response at this time. City staff has implemented temporary erosion control measures to help avoid further erosion until repairs can be made. Senior Civil Engineer Laurie continued with a report on the current structural condition and staff recommendation related to the bridges located at Heritage Park. The bridges in and around Heritage Park were evaluated in 2011 by an outside engineering consultant who recommended full replacement of all bridges and provided recommendations for interim repairs. Given the time that had lapsed since 2011, staff engaged the outside consultant to re -asses the five bridges located at the park. The updated reassessment which analyzed a number of alternatives for restoration or replacement was completed in September 2019. The updated report recommended replacement of each of the five bridges. Removal and replacement of all five bridges with cast -in -place or precast concrete bridges was estimated at $1.8 million (Option 1). Alternatively, one of the options provided in the report was to eliminate the two westerly bridges (Bridges C & D) and combine the three remaining bridges at the equestrian center entrance (Bridges E, F, & G) into a single bridge with a barrier fence to separate the vehicles from pedestrians and equestrians (Option 2). This latter option was estimated at $1.1 million. The construction timeline for either option is approximately 3 years. It was noted that no funding is available at this time but Fire District reserves could potentially fund 50% of the combined bridge at the entrance October 30, 2019 1 Public Works Subcommittee City of Rancho Cucamonga I Page 1 of 2 CITY OF RANCHO CUCAMONGA I PUBLIC WORKS SUBCOMMITTEE SPECIAL MEETING MINUTES October 30, 2019 to the equestrian center since the vehicle bridge provides access to the equestrian center for use as a fire staging area. The remaining costs would need to be funded out of PD-85 which does not have reserves available to cover the costs for this project and address anticipated replacements and repairs at Heritage Park and Red Hill Park. Following the presentation, Mr. Henderson expressed concerns related to access to the equestrian center and the proposed combined bridge at its entrance. After discussion the Sub -Committee voted on the staff recommendation included in the staff report: 1. Recommend that the City Council include Option 2 for the Heritage Park Bridge Replacement Project consisting of replament of three bridges at the entrance of the equestrian center with one consolidated bridge and removal of the remaining two bridges utilizing the funding sources as described in the staff report below in Fiscal Year 2020/21 CIP Budget; and 2. Receive a report on the status of the Randolph Davis Property Community Trail deferring recommendation regarding short- and long-term reconstruction of the Davis Trail until a decision on the insurance claim has been received. Motion by Council Member Hutchison, seconded by Mayor Pro Tern Kennedy to accept the staff recommendation. Motion approved. D1. The Public Works Sub -Committee meeting adjourned at 4:08 pm. Date: Respectfully submitted, Jason C. Welday Director of Engineering Services/City Engineer October 30, 2019 1 Public Works Subcommittee City of Rancho Cucamonga I Page 2 of 2 STAFF REPORT DATE: March 18, 2020 TO: Public Works Subcommittee FROM: Jason C. Welday, Director of Engineering Services/City Engineer INITIATED BY: Gianfranco Laurie, Senior Civil Engineer SUBJECT: Update on the Heritage Park Bridges RECOMMENDATION: Staff recommends that the Public Works Subcommittee recommend replacement of three parallel bridges to the equestrian center with a single bridge structure with physically separated pedestrian/equestrian/and vehicle uses, while leaving the two westerly bridges in place with regular monitoring and forward that recommendation to the City Council. BACKGROUND: An initial bridge evaluation of seven bridges in and around Heritage Park (Bridges A through G) was completed in March 2011. The initial bridge evaluation recommended replacement of the bridges though it also identified minor repairs for each bridge to extend their useful life. In 2019, an updated bridge report reassessed the five bridges at Heritage Park (Bridges C through G). The report analyzed various bridge alternatives which included new concrete bridges, combining the existing three parallel bridges into one bridge (while separating the pedestrian, equestrian, and vehicle traffic), and replacing bridges with an in -kind construction material. An estimate to replace all five bridges was prepared and costs were estimated to be as high as $1,840,000 for design and construction. The report concluded by recommending future restorations or replacement measures for each bridge. On October 30, 2019, staff shared the report with the Public Works Subcommittee. An option recommended was replacing the three parallel bridges (Bridges E, F & G) with a single bridge with a barrier separating vehicles from pedestrians and equestrians. This option estimated at $1.2 million. One advantage of a single underlying bridge structure is that it leverages an option not otherwise available to allow Fire District reserves to assist with funding up to 50% of the structure, given that this is the only emergency vehicle access point to the facility which is utilized as a fire staging area to help protect the surrounding community during wildfires in the adjacent mountains. The remaining 50% would then be potentially funded with Park Development District No. 85 (PD- 85) reserves. The committee recommended the City Council consider allocating funding in the Fiscal Year 2020/21 CIP Budget for the single bridge with separated uses. Following the Public Works Subcommittee, staff re-engaged the consultant to conduct a more detailed structural evaluation of each bridge. A supplemental engineering study was prepared that documented exploratory investigations, structural calculations, and load demands. Significant Page 1 of 8 exterior deterioration, noted delamination, fractures, and insect activity was identified at the two westerly bridges (Bridges C and D) and main vehicular bridge (Bridge F). The load demands determined for the two westerly (Bridges C and D) independently indicated they could carry a combined weight of a 16-hand horse, tack, and rider estimated up to 2,000 pounds. Further, the load demand determined for Bridge F indicated it could hold a single rear axle fire engine ranging between 24,000 to 35,000 pounds. Additionally, preliminary cost estimates were included in the study using various materials such as concrete, steel, and timber. The purpose of this study was to provide better structural information for decision -making as well as to discuss future bridge restorations or replacements with the City's advisory groups. On February 12, 2020, staff presented all the findings received to date to the Trails Advisory Committee. A letter furnished by the Alta Loma Riding Club (ALRC) was submitted that opposed the removal of any bridge as well as installation of one combined bridge. ALRC's feedback was that replacing all five bridges at one time is essential to maintain public access, recreational opportunities, and public safety, regardless of cost. Staff explained that based on the findings received the best option now is to replace the three parallel bridges (Bridges E, F & G) with a combined bridge, while separating the pedestrian/equestrian/vehicle uses, as the Fire District could potentially fund 50% of the anticipated costs. Moreover, the two westerly bridges (Bridge C & D) would remain open for the immediate future with regular monitoring until they reached end of life. The Trails Advisory Committee meeting concluded with a unanimous recommendation to allocate the $1.2 Million and replace the three parallel bridges with a single bridge with separated uses, while leaving the two westerly bridges in place with regular monitoring. Also, the Trails Advisory Committee agreed with staff to proceed with temporary improvements such as installing new signs and striping for Bridge C, Bridge, and Bridge F as a result from the supplemental engineering study. Subsequently, staff shared the same findings and the Trail Advisory Committee's recommendation with the Planning Commission on March 11, 2020. The The Planning Commission meeting concluded with a unanimous recommendation to allocate the $1.2 Million and replace the three parallel bridges with a single bridge with separated uses, while leaving the two westerly bridges in place with regular monitoring. ANALYSIS: As mentioned previously, significant exterior deterioration has occurred to three bridges. The two westerly bridges (Bridges C & D) that serve pedestrian and equestrian traffic to access park amenities such as the adjacent wilderness area, a short-cut access to the main park, and an additional access point to the equestrian center. The third bridge with significant deterioration, the vehicle bridge (Bridge F), is one of three parallel main bridges that provide access into the equestrian center as well as serves as access for the Fire District's staging area. Pictures on the subsequent pages depict insect activity, decayed wood planks, discolored wood planks, longitudinal cracks and fractures in the beam supports. Page 2 of 8 Y ti .F • h�ti `zi Bridges C & D Close Up Bridge C Page 3 of 8 i A..1;- -W Bridge F Bridges E & G are the other two main bridges parallel to Bridge F that provide access into the equestrian center. An image included on the subsequent page illustrates all three parallel main bridges. Bridge E serves pedestrians (outer left), Bridge F serves vehicles (middle) and Bridge G serves equestrians (outer right). The materials comprised for each bridge noted include concrete supports, wood beams, wood planks, and asphalt concrete pavement overlay only for the middle vehicle bridge. Page 5 of 8 Independent Bridges E, F & G Staff recommends combining the three parallel bridges (Bridge E, F & G) into one bridge that provides separation for vehicle, pedestrian, and equestrian uses. Presently all three parallel wood structures are independent with open voids in between bridges spanning longitudinally 80 feet along the Demens Creek Channel. The proposed combined bridge structure would remove the open voids with constructing one concrete superstructure spanning a total length of 50 feet across the Demens Creek Channel. This concrete bridge structure would include dedicated pathways for vehicles, pedestrians and equestrians that would keep the uses separated. A rough broom finish will be applied throughout the bridge surface to provide better traction for horses. Furthermore, constructing a concrete bridge structure will significantly reduce maintenance, extends the lifespan, and ensure uniformity with current city standards. An architectural rendering of what the proposed structure might look like is illustrated below. Combined Bridge (Uses separated) Given the current condition of the bridges, staff has developed a tentative schedule that identifies all major milestones and target dates to construct a single bridge with separated uses. The overall process from City Council approval to design and then construction will take approximately two Page 6 of 8 (2) years to complete. The next steps are review and consideration by the City Council. A brief outline of the tentative schedule is shown on the subsequent page. Milestone Target LMD Oversight Committee March 17, 2020 City Council May/June 2020 Conceptual Design October 2020 (3 months) Design Drawings (PS&E) March 2021 (8 months) Permits May 2021 (10 months) Bid and Award June 2021 (3 months) Construction March 2022 (8 months) Tentative Schedule Staff recommends that the Public Works Subcommittee recommend replacement of the three parallel bridges with a single bridge with physically separated uses, while leaving the two westerly bridges in place with regular monitoring, and forward that recommendation to the City Council. FISCAL IMPACT: Combining the three parallel bridges (Bridge E, F & G) into a single bridge with separated uses will result in a total estimated cost of $1.2 million. As noted earlier, funding for the combined concrete bridge structure would be split 50% between the Fire District and the other 50% from PD-85 reserves. An estimated cost breakdown is provided below. Bridge Type Fire District PD-85 Combined Reserves Reserves Funding Single Bridge with Separate Uses (Vehicle, Pedestrian, & $420,000 $420,000 $840,000 Equestrian) Includes Prelim Eng., PS&E, $189,000 $189,000 $378,000 Inspection, & Permits Total $609,000 $609,000 $1,218,000 Estimated Costs Given the other deferred maintenance needs and aging infrastructure at both Red Hill and Heritage Parks, as well as cash flow needs, PD-85 does not presently have sufficient reserves to fund all five bridge replacements which is estimated at a cost equal to or greater than $1.8 million. Further, because PD-85 is using 30 year old assessment rates to fund current day costs, and the residents of the district have to date rejected any revenue increases, it is unlikely that PD-85 will be able to save up additional funds on its own, or repay a loan from the General Fund. Page 7 of 8 Consistent with existing City Council policy, all landscape and park districts city wide (east and west, north and south) are intended to be self-sustaining and receive an equitable level of support from the General Fund without disproportionately favoring any one district. The only potentially fiscally viable alternative which is within existing City Council approved policy is to leave the two western bridges (Bridge C & D) open but continuously monitored for safety and concurrently combine the eastern three parallel bridges (Bridge E, F & G) into a single, use separated bridge which would then be eligible for partial funding by the Fire District.
