PUBLIC COMMENT Resilient by Design Project Scope Presentation (Hassell+) V. DISTRICT PROJECTS, ETC.: SUMMARIZED IN A HANDOUT AND OPEN FOR Page M2 of M5 ADDITIONAL DISCUSSION • El Camino Box Culvert and Mission Road Diversion Structure Ann reminded the committee that as previously reported, the District selected the consultant firm of CDM-Smith to perform a condition assessment of the box culverts starting approximately 300 feet north of the intersection of El Camino Real and “A” Street in Daly City to the beginning of the BART section at the Treasure Island Mobile Home Park. The total length of culvert to be inspected is approximately 8,660 feet or 1.6 miles, which includes the segment under Mission Road that is approximately 1,089 feet and consists of a double box (two boxes placed side by side). The District received an encroachment permit from Caltrans on October 31, 2017, for the consultant to access the box culverts in El Camino Real (State Route 82). Due to the start of the rainy season, the District and the consultant agreed that it would be prudent to delay the start of inspection until late spring or early summer 2018, as the work is dependent on weather and amount of flows in the culvert/boxes. CDM-Smith plans to begin the inspection in April 2018, weather permitting. The anticipated duration to complete the project is 3-4 months. Delaying the start did not affect the consultant’s cost proposal. • BART Co-op Project Ann reported that with authorization from the District, the Town of Colma performed vegetation management and graffiti abatement on the upstream segment of the BART project (McLellan Drive to Mission Road) under the Memorandum of Agreement (MOA) for shared services. The Town’s invoice for the graffiti abatement and vegetation management was $28,500 for the period of August 1, 2017, to September 30, 2017. District hired contractors also completed removal of pampas grass (including root balls) on the access road adjacent to the Oak Avenue Bridge, spot repairs of concrete within the channel, and fence repair work. The cost incurred for these repairs totaled $65,386.16. Some of the completed repairs were items on the BART punchlist, which will be invoiced to BART. Additional BART items within the channel between McLellan Drive and Mission Road are anticipated to be performed during summer 2018. Costs associated with items on the BART punchlist, which have not been determined yet, will be invoiced to BART for payment. • Colma Creek Improvements between Spruce and San Mateo Avenues No particular update was reported on this section of the channel to report except that the District will continue to monitor this section of channel regularly for wall movement or settlement at a segment of the south wall immediately downstream of the San Mateo Avenue Bridge. • Mitigation Sites downstream of Utah Avenue Ann shared that district staff and Sheriff Work Program (SWP) participants continue to perform planting, weeding, and trash pick-ups at the five Mitigation Sites (2a, 2b, 2c, 3, and 4). The next SWP cleanup date has been scheduled for March 17, 2018. In addition, the District hosted planting events on January 20, 2018, and January 27, 2018, Page M3 of M5 with the assistance of Shelterbelt Builders, Inc. The January 20th event included 27 volunteers from the Alta Loma Middle School and several County employees, and the January 27th event consisted of eight SWP workers. Over 1,100 individual native plants were planted at Mitigation Sites 2 and 3. Kamela Silva Wolfe inquired as to where the plants are obtained from. Ann replied that they are obtained from local nurseries. The following table summarizes the amount of trash removed from the Mitigation Sites since 2005 and the trash pick-up dates from 2015 through 2018. An additional 6.97 CY of trash have been removed from the Mitigation Sites since the last Advisory Committee meeting. Year Amount of Trash Removed (Cubic Yard) Event Dates * 2018 5.23 1/6, 1/20, 1/27, 2/10, 2/24 2017 41.80 1/7, 1/21, 2/4, 2/18, 3/4, 3/11, 3/18, 4/1, 4/22, 5/6, 5/20, 6/17, 7/15, 8/19, 9/16, 9/30, 10/21, 11/18, 12/2, 12/21 (20 times) 2005 - 2016 575.08 12-19 times per year. Total 622.11 * Number of event dates increased per mitigation required for Channel Wall Repair Upstream of Spruce Avenue. • Maintenance of Existing Channel Ann reported that the quarterly inspection of the Colma Creek Flood Control Channel was performed on February 9, 2018, (See photos in Maintenance Matrix Binder). Representatives from the City accompanied District staff during the inspection. Several homeless encampments were observed under bridges, on access roads, and within Mitigation Site 2. The encampments in Mitigation Site 2 were abated by South San Francisco City staff on January 23, 2018; however, several homeless individuals immediately returned and began rebuilding encampments. Illegal dumping of garbage, furniture, and construction debris along the channel walls near Mitchell Avenue (between S. Airport Blvd. and Utah Avenue) is a significant problem with a number of homeless inhabitants living out of vehicles parked in the vicinity. Issues requiring enforcement by the City or the Town have been forwarded to the respective entity. • Produce Avenue – Channel Wall Project There is no update on this project. The District continues to monitor the channel walls immediately upstream and downstream of the Produce Avenue Bridge. The consultant CDM-Smith continues to work on developing preliminary concepts for the repair of the channel walls. The draft report was submitted on February 22, 2018, and is currently under District review. To facilitate the inspection of the box culverts in the upper reach of the channel, CDM-Smith’s budget initially allocated for the next phase of this project was reassigned to the box culvert inspection work. Based on cost estimates provided by CDM-Smith, the additional budget required to complete additional analysis and engineering design of the selected concept for the project would exceed the amount approved by the Board of Supervisors on the current agreement which is to expire in November 2018. They may be performed by another consultant or continued by CDM-Smith if a new agreement is awarded Page M4 of M5 by the County. The District is considering the options for completion of this project work and the preferred path forward. • Utah Avenue to Bay Ann reminded the committee that the District submitted to the California Governor’s Office of Emergency Services (CalOES) multiple applications for FEMA Hazard Mitigation Grant Program (HMGP) funding of the flood walls downstream of the Utah Avenue bridge since June 2016. On November 30, 2017, CalOES informed the District that it has completed its review of the application and has submitted it to FEMA for grant review and funding consideration. On February 24, 2018, CalOES provided an update on the FEMA review which stated that it is now in Environmental Review process, which could take anywhere from several months to years to approve. While the District continues to wait for a decision from FEMA the preliminary design of the project is in progress. The consultants selected for the design completed the 65% design submittal in November 2017. Based on the review of the submitted documents, the District directed the consultants to perform additional geo probes and soil investigation near a potentially culturally sensitive site. The report summarizing the results of these geo probes was submitted on March 5, 2018, which concluded that the proposed project will not affect any surface or subsurface archaeological resources. With this information, the consultants will be able to proceed with finalizing the draft Initial Study/Mitigated Negative Declaration for California Environmental Quality Act (CEQA) clearance and provide it to FEMA for National Environmental Policy Act (NEPA) compliance when FEMA determines to fund the project. The final design is anticipated to be completed in the spring/summer of 2018. • Sea Level Rise Preparedness Ann informed the committee about Resilient by Design | Bay Area Challenge (RbD), a collaborative research and design project that brings together local residents, public officials, and local, national and international experts to develop innovative solutions to the issues brought on by climate change that the San Francisco Bay Area faces today. The HASSELL+ team was recently selected by the RbD for the South San Francisco element of the project. The HASSELL+ team has been invited to attend this Committee meeting by Supervisor Pine’s office to brief the Committee on its project scope (Attachment #1) and activities to date. Attachment #2 is a copy of the slides from the HASSELL+ team presentation at a recent meeting held in South San Francisco. Next steps would be to determine how to integrate with County and City Tour. • Multi-jurisdictional Regional Stormwater Capture Project at Orange Memorial Park (SSF and San Mateo Countywide Water Pollution Prevention Program) Richard Irli inquired about how large, deep, and/or spread out the project would be. It was reported that the design should be started in June of 2018, complete 100% plans and specifications by Spring of 2019, and out for bid by Summer of 2019. The anticipated stormwater storage capacity of the project is approximately 2 million gallons. As previously reported, a funding agreement between the City and Caltrans for this project was approved by the City Council on April 26, 2017. City awarded the design contract to Lotus Water, a water resource and civil engineering design firm located in San Francisco, on Page M5 of M5 January 24, 2018. Justin Lovell reported the 02/20/18, kickoff meeting will include three conceptual designs to be reviewed by the geotechnical engineer and then presented for further review by the committee, Planning Commission, and the Parks & Recreation Department. Helen Fisicaro reminded the committee that the soccer fields in Daly City are artificial and may be a consideration in a design that places the facilities underground. Justin Lovell indicated that the Parks & Recreation Department is looking into options that would work with active recreation on top. • Colma Creek Technical Advisory Committee (TAC) The TAC met on January 16, 2018, to continue the discussion on collaboration between the District and SSF, Daly City, and Colma for maintenance type activities. The TAC also discussed concepts for CIP Project #8 (Master Plan, modernization, and Hydrologic Analysis of Channel) and collaboration with County Enhanced Flood Control to develop a joint scope of work for modeling both Colma Creek and Navigable Slough channels as a combined project. District will be conducting an inventory of the existing models to present to the TAC at its April 2018 meeting. Resilient by Design is updating/combining modeling efforts. VI.
