HomeMy WebLinkAbout03-21-2017 Item 10 - Laguna Lake ADA Trail Meeting Date: 3/21/2017 FROM: Daryl Grigsby, Director of Public Works Prepared By: Dan Van Beveren, Senior Civil Engineer SUBJECT: LAGUNA LAKE ADA TRAIL RECOMMENDATION 1. As recommended by the Parks and Recreation Commission, approve plans and specifications for the Laguna Lake ADA Trail, Specification No. 91388; and 2. Authorize staff to formally advertise for bids; and 3. Authorize the City Manager to award the construction contract including the Base Bid and Additive Alternates within the project construction budget of $220,000. DISCUSSION Background The Laguna Lake Natural Reserve is located along the northeastern edge of Laguna Lake, immediately north of Laguna Lake Park. As new hiking trails within the City open space network have been developed, the City has come to recognize the need for trails which are compliant with the Americans with Disabilities Act (ADA). The purpose of this project is to upgrade an existing Laguna Lake Natural Reserve trail to make it accessible to all users. The Laguna Lake Natural Reserve is located in a relatively flat area, adjacent to the northern portion of Laguna Lake Park, and is an ideal location for an ADA-compliant trail. Attachment #A depicts the site location and the proposed alignment of the ADA trail. Design Considerations A variety of options were considered for surfacing of the ADA-compliant trail including concrete, asphalt, and decomposed granite. Ultimately, both asphalt and concrete were not preferable for this project since these materials would negatively impact the appearance and natural setting of the open space. The most natural looking material, decomposed granite was selected as the preferred surfacing. Decomposed granite paths require considerable ongoing maintenance in order to maintain ADA compliance. This material deteriorates over time and develops areas of loose sand, weeds and other vegetation growth; and eventual rutting could render the path non-ADA accessible. However, decomposed granite when combined with a polymer resin has shown that it reduces maintenance efforts, is permeable, and provides the most aesthetic alternative to cement of asphalt. The polymer resin decomposed granite material is estimated to cost approximately 33% more than asphalt concrete, but considered preferable to reduce impacts to the natural setting of the open space. The polymer resin decomposed granite specification has been incorporated into the proposed project. CONCURRENCES Packet Pg. 145 10 This project is the result of a collaborative effort between Public Works, Parks and Recreation, and the Natural Resources Division of the Administrative Department. All three Departments are in agreement with the project scope and design. A grading permit application was submitted to the Community Development Department’s Building Division in December 2016. This permit was approved in February 2017, and will be issued to the contractor following the award of a construction contract. All comments and conditions associated with the Building and Safety review of the project have been incorporated into the design of the project. This project was presented to the Parks and Recreation Commission on July 6, 2016, who approved the project. Meeting minutes are included as Attachment #B to this report. ENVIRONMENTAL REVIEW The design was presented to the Community Development Department (CDD) for environmental review. It was determined by CDD staff to be categorically exempt from environmental review pursuant to CEQA Guidelines Section 15301 (maintenance or replacement of an existing facility) and was issued a Notice of Exemption. FISCAL IMPACT The 2015-17 Financial Plan, Appendix B, pages 3-269 through 3-272 includes $250,000 for the design and construction of this project. The current available balance is $248,450. The project is structured with a Base Bid and three Additive Alternates. In order to maximize the length of trail constructed within the available funding. The strategy is to award the contract with the Base Bid and as many of the Additive Alternates as funding will allow, up to a construction contract amount of $220,000. The Base Bid portion is immediately adjacent to the edge of Laguna Lake Park, and each Additive Alternates extends the trail further north along the edge of Laguna Lake. Packet Pg. 146 10 The project’s construction budget is shown in the following table: Budget Construction Contract $220,000 Construction Contingencies $25,000 Total for Construction $245,000 Printing and other Misc. Costs $500 Materials Testing $2,500 Total for other costs:$3,000 Total Project Cost $248,000 Amount Available:$248,450 Once the project is advertised, and bids are received, the recommended action will allow the City Manager to award a construction contract if the Base Bid is less than $220,000. Additionally, the action also authorizes the City Manager to include Additive Alternatives in the contract if the total contract cost is under $220,000.

Packet Pg. 149 10 Minutes – Parks and Recreation Commission Meeting of July 6, 2016 Page 2 PUBLIC HEARINGS BUSINESS ITEM 3. Presentation of Bishop Peak Preparedness Plan Fire Chief Garret Olson presented to the Commission an update of the preliminary assessment of emergency response access and citizen egress in the area around Bishop Peak trail. The Fire Chief Olson said that in response to concerns expressed by residents in the area of the Bishop Peak trail, the Fire Department and Information Technology (IT) Graphic Information Systems GIS) staff conducted a study to assess the risk in the region and in other wildland interface areas, the City Fire Department’s ability to access areas at risk, and the ability of residents and visitors to evacuate if so advised by emergency response personnel. He added that to fully assess the risk, city staff developed scientific modeling for several scenarios related to a fire started in this region and in other wildland interface areas of the City. Based on a preliminary assessment of the GIS modeling and the access and egress needs, the Fire Department determined the Bishop Peak area to be unique and developed a concept plan to discontinue all on street parking on both sides of Highland Drive starting at Oakridge Drive as well as on the west side of Oakridge Drive starting at Highland Drive. He added that there are currently no air craft available in San Luis County that could be used for an immediate mutual aid fire response. Staff is recommending a fuel reduction focus area at the top of Highland Drive (at trailhead access). Fire Chief Olson said that this initial concept to restrict parking along Highland and Oakridge drive is open to complete revision if more creative or different solutions come to light during the process which provides for the minimum necessary access and egress in the event of a fire in this region. Questions for the Parks and Recreation Commission to consider for this region include: a) What possible solutions to reduce fire risk would the Commissioners encourage City staff to consider, including such topics as street and parking design and vegetation management on City controlled property? b) In support of no parking recommendation, vegetation management and education awareness, landscape awareness c) What possible solutions to enhance Fire emergency response access and operations would the Commissioners encourage City staff to consider? Previous Commission public meetings to discuss alternate dirt road to allow fire access through open space there was neighbor opposition of this proposal. Director Stanwyck noted MTC studies where transportation could be improved to meet community needs. There is a bus stop on Highland and Patricia, bike racks at trailheads and weekend shuttles to trailheads. Commissioner Avakian consider closing the Highland Trailhead. Fire Chief Olson added that the City could explore policy amendments to allow private property assistance with fire mitigation efforts such as weed abatement Packet Pg. 150 10 Minutes – Parks and Recreation Commission Meeting of July 6, 2016 Page 3 and/or modernization of building codes (new roof materials, spark arrestors, fire resistant exterior, fire sprinklers, etc.) c) What possible solutions to ensure sufficient resident and visitor evacuation needs would the Commissioners encourage City staff to consider? Discontinue parking and designated a walking path, with vehicle access to one side. Additional No smoking signs at trailheads. Flyers or pamphlets given to residents that live in high fire danger areas. City Staff anticipates presenting to the City Council with recommendations and funding options as part of the next Financial Planning process. Commission Comments followed. Commissioner Olson asked if the scenarios included a response from the Fire Department. Nicola responded yes, the modeling is based upon worst case scenario. Vice Chair Updegrove asked if fires have occurred here before. Chief Olson responded yes, typically cause by birds on electrical wires. Commissioner Schwab asked how many people would be displaced with the limiting parking. Director Stanwyck responded that this area is private property which the City not control. She added that the nearby school has significant parking which is available to the public for use. Director Stanwyck said that Patricia Lane can hold 30-40 parking spots – mostly adjacent to undeveloped property. Commissioner Single asked how to prevent fires in this region. Chief Olson responded that there are a multitude of factors that contribute to fire prevention and mitigation such as vegetation management, restriction of parking, defensible space among residential homes and community awareness and education about the risks of this area. Chair Whitener, modeling for mitigation activities. Chief Olson said they can remodel based on site -by- site assessments but unfortunately much of the fire risk is located on private property. Public Comments: Landy Fike, SLO Resident, asked if there are laws for private property vegetation clearance that confronts the streets. Chief Olson said that Public Works has provided the minimum standards for clearance for this area in public right-of-way. 4. Update for Laguna Lake Park Accessible Trail Project Senior Civil Engineer, Dan VanBeveren, presented a project update to the Commission with proposed recommendations for construction of the Laguna Lake Park ADA Accessible Trail. The Laguna Lake area has been identified as an ideal location for an accessible trial due to its flat topography. Staff VanBeveren added that the intent of the project was to upgrade an existing trail, which runs along the northeastern edge of Laguna Lake, and to add a new section of trail along a small peninsula near the southern end of the existing trail. He added that by utilizing decomposed granite as the surface type for this project, it would require considerable ongoing maintenance to maintain ADA compliance. In recognition of these challenges, staff is recommending utilizing a commercial product which uses Packet Pg. 151 10 Minutes – Parks and Recreation Commission Meeting of July 6, 2016 Page 4 decomposed granite mixed with cement as a binding agent (resin-based binder) – a method which has worked well in maintaining the integrity of the pathway surface. Staff VanBeveren added that it is very unlikely that the entire length of the new trail can be installed with the total project budget of $250,000. Director Stanwyck added that the Sinsheimer Playground Project has recently received a grant which would now free up a portion of general funds which could be used for this project. Staff VanBeveren said the amount of the overall general fund savings of the Sinshiemer Playground Equipment Replacement project would be dependent upon the amount of level of project bids received. Staff will have more certainty of available funds once that project is awarded. Questions for the Parks and Recreation Commission to consider are: a) What surface type would be preferred by the Commissioners in the construction of the new ADA accessible trail at Laguna Lake Park? Resin aggregate flexible p and recommends a sight visit to a location that has used this material to observe how well it holds up. b) What surface color would be preferred by the Commissioners in the construction of the new ADA accessible trail at Laguna Lake Park? Natural Colors, tan aggregate resin surface with natural gray concrete. c) As a result of limited project budget it is unlikely that the accessible trail system can be constructed in its entirety (approximately 3100 feet of trail network). Staff is recommending construction of the shorter “ peninsula trail” loop be completed first, with the construction of the northern trail connections occurring in later phases as additional funding is made available. i. Is the Commission in support of staff’s recommendation to construct the peninsula trail loop first as part of the project’s “ base bid”? Yes ii. What other possible solutions to maximize trail construction would the Commission encourage City staff to consider? Exploring of other grant funds Commission Comments followed. Commissioner Avakian asked if the resin materials had a more rubberized feel. Staff VanBeveren marketed as a natural looking pavement surface. He added that there is a trail leading up to Golden Gate Park that uses this material. Vice Chair Updegrove asked how long this material has been in place. Staff VanBeveren utilized a local consultant to provide the materials research and provide recommendations for use in this application. Commissioner Avakian asked if there was enough current ADA parking spot at this trailhead location. Staff VanBeveren said there is currently one disability parking spot available. Director Stanwyck said additional parking spaces could be considered once the need for additional ADA parking has been exceed. Public Comments: None. ACTION: MOTION BY COMMITTEE MEMBER OLSON, SECOND BY VICE CHAIR UPDEGROVE, to recommend City Council approval of the resin aggregate material with a Packet Pg. 152 10 Minutes – Parks and Recreation Commission Meeting of July 6, 2016 Page 5 natural color gray concrete, with the construction of the peninsula trail a priority for construction. Recommend Council’s approval of additional funds from the Sinsheimer Playground Project be applied to this project for complete trail construction. Motion passed 6:0:0:0 on the following roll call vote: AYES: AVAKIAN, OLSON, SINGLE, SCHWAB, UPDEGROVE, WHITENER NOES: ABSTAIN: ABSENT: 5.
