DISTRICT PROJECTS, ETC.: SUMMARIZED IN A HANDOUT AND OPEN FOR ADDITIONAL DISCUSSION 1. El Camino Box Culvert and Mission Road Diversion Structure Ann advised that the District is working on retaining a consultant 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. Work will include an inspection of the channel, development of a detailed structural assessment and repair recommendations, mapping of all storm drain inlets within the project vicinity, and a full report with the above information. The box culverts were built approximately in 2000-2001. The purpose is to do an assessment of the conditions, as they have not been assessed since the boxes were built. 2. BART Co-op Project Ann advised that there are no updates on this section of the channel to report. 3. Colma Creek Improvements between Spruce and San Mateo Avenues Ann advised that there are no updates 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. There have been no changes since the last inspection. 4. Mitigation Sites downstream of Utah Avenue Ann advised that the 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 June 17, 2017. The District’s contractors have continued to perform monthly maintenance at Site 4 and quarterly maintenance at Sites 2 and 3. This schedule was developed based on the amount of work anticipated to maintain the sites and increase or sustain plant survival rates. A total of 24 volunteers participated on National River Cleanup Day and Earth Day cleanup events, which took place on April 22, 2017, and May 20, 2017, respectively. The following table summarizes the amount of trash removed from the Mitigation Sites since 2005 and the trash pick-up dates from 2015 through 2017. An additional 8.08 CY of trash have been removed from the Mitigation Sites since the last Advisory Committee meeting. - 3 - Year Amount of Trash Removed (Cubic Yard) Event Dates * 2017 21.43 1/7, 1/21, 2/4, 2/18, 3/4, 3/11, 3/18, 4/1, 4/22, 5/6, 5/20 2016 33.00 1/2, 1/23, 2/13, 2/27, 3/19, 4/16, 4/23, 5/14, 5/22, 6/11, 7/23, 8/20, 9/17, 9/24, 10/22, 11/5, 12/3, 12/17 (18 times) 2015 38.98 1/10, 1/24, 2/7, 2/21, 3/7, 3/21, 4/4, 4/18, 5/2, 5/16, 6/20, 7/18, 8/15, 9/13, 9/19, 10/17, 11/14, 12/12 (18 times) 2005 - 2014 503.10 12-19 times per year. Total 596.51 * Number of event dates increased per mitigation required for Channel Wall Repair Upstream of Spruce Avenue. 5. Maintenance of Existing Channel Ann indicated that in order to address recurring homeless encampment issues under the San Mateo Avenue Bridge, the District authorized the City of South San Francisco (City) to install new fences at the bridge abutments under the recently executed Memorandum of Agreement (MOA) for shared services. There hasn’t been any feedback about whether the fences are working to keep people out. The quarterly inspection of the Colma Creek Flood Control Channel was performed on May 16, 2017 (See Maintenance Matrix Binder). Representatives from the City accompanied District staff during the inspection. Issues requiring enforcement by the City or the Town have been forwarded to the respective entity. As previously noted, the District submitted the permit applications for the long-term maintenance permit to the regulatory agencies on December 29, 2015 and the Initial Study/Mitigated Negative Declaration (IS/MND) to the State Clearing House on June 10, 2016. On October 18, 2016, the IS/MND was approved by the County Board of Supervisors. The Notice of Determination was filed with the State Clearinghouse thereafter to complete the CEQA process. The California Department of Fish and Wildlife permit has been finalized and the District is prepared to sign it once permits from the US Army Corps of Engineer (Corps) and the State Regional Water Board have been issued. It is anticipated that the Corps permit to the District could be issued prior to the end of June 2017. At the last Advisory meeting the District had anticipated this to be May 2017. Mark Chow indicated that the process with the Corps would be “wrapped up next week,” according to the consultant. It was clarified that this will be a five year permit. The graffiti on channel walls can be painted over now, before the permit is received. Brad Donohue clarified that they are waiting for the water levels to go down for worker safety due to mossy conditions and pampas grass. Town of Colma needs to submit cost breakdown for the abatement and receive approval from the District. “No spray” policy requires a mechanical abatement. City of South San Francisco is awaiting staff availability to proceed on the section that is within City jurisdiction. - 4 - A new bathymetric survey of the channel between US 101 and the Navigable Slough has been completed. The new survey information will be used to evaluate sediment accumulation in this section of the channel to determine the need for dredging (Capital Improvement Program Project #7). The District has requested a proposal from a consultant to perform the work to develop channel cross sections intended to depict the level of sedimentation within the channel since the last survey was completed in 2013. The scope of work will also include revisions to the hydraulic model that would forecast flow conditions during a 50-year storm event and projected sea level rise. 6. Produce Avenue – Channel Wall Project The District continues to monitor the channel walls immediately upstream and downstream of the Produce Avenue Bridge. Also as previously reported, the District authorized CDM-Smith to perform geotechnical and geophysical investigations on the cause of the wall movements, develop repair options, and prepare a report with recommendations for a Not-to-Exceed amount of $260,320. Two borings outside of the Caltrans right-of-way, as shown on the map below, have been completed (B-1 and B-2). The remaining two borings within Caltrans right-of-way, which are more difficult to access and would require coordination with Caltrans for traffic control to close the US101 southbound exit ramp to southbound Produce Avenue and temporary lane closures for both northbound and southbound Produce Avenue, will be done once the District receives the encroachment permit from Caltrans. The encroachment permit was initially submitted to Caltrans on September 27, 2016. District staff re-submitted the permit application to Caltrans on February 17, 2017 based on Caltrans’ comments. The permit was received on April 10, 2017 and boring work is scheduled to be performed on June 28, 2017. The draft report and alternative design concepts are anticipated to be submitted to the District within 4 months after all borings have been completed. The Caltrans permit requires work to be performed at night, with ramps closing at 8:00 pm. It took about seven months to obtain the permit. 7. Utah Avenue to Bay Ann advised that as previously reported, the District submitted to the California Governor’s Office of Emergency Services (CalOES) a full application for FEMA Hazard Mitigation Grant Program (HMGP) funding of the flood walls downstream of the Utah Avenue bridge on June 16, 2016. A revised application was re-submitted on September - 5 - 7, 2016 to include pre-award costs and address storm surge condition (in addition to the 100-year event, 100-year tide, 3 ft. of freeboard), and the SLR for the projected useful life of the project, which increased the total project costs from $4,100,000 to $4,280,000. The additional cost would be funded with Zone revenue as the maximum allowed grant amount remains at $3,000,000. The District received a letter from CalOES dated October 28, 2016 with confirmation that the application has been put on a waiting list to be submitted to FEMA if funding becomes available. In late March 2017, CalOES informed the District that more funding has become available for HMGP funding due to the declaration of various emergencies as a result of the severe winter storms. The District was encouraged to submit another application for the project under the new funding program. The District submitted the application to CalOES on April 10, 2017, and is currently awaiting the result of the application review by CalOES and FEMA. The District is proceeding with the preliminary design of the project in which case the expenditures would be considered as part of the 25% local match. The consultant selected for the preliminary design has completed the topographic/bathymetric surveys and geotechnical investigations in April and May of 2017. Work on the technical studies required for environmental compliance and preliminary design is scheduled to start in July of 2017. The final design is anticipated to be completed in the spring of 2018. 8. Sea Level Rise Preparedness Ann advised to see discussion under Maintenance of Existing Channel section regarding the hydraulic modeling to be performed based on the latest survey data and Utah Avenue to Bay section regarding potential grant funds to include design elements to include SLR mitigation in the construction of the project. 9. Multi-jurisdictional Regional Stormwater Capture Project at Orange Memorial Park (SSF and San Mateo Countywide Water Pollution Prevention Program) Ann advised that a funding agreement between the City of South San Francisco and Caltrans for this project was scheduled to be considered by the City Council on April 26, 2017, and funded in the 2018 CIP. Eunejune Kim confirmed that this project is listed in the next budget cycle. Ann explained that Caltrans has a certain amount of work they need to complete to comply with Storm Water Permits and requirements but they don’t have enough right of way or space to complete; therefore they work with agencies to find locations to implement projects to improve downstream impact. 10. Colma Creek Technical Advisory Committee (TAC) Meetings Ann advised that the TAC met on April 11, 2017, to continue the discussion on collaboration between the District and SSF, Daly City, and Colma for maintenance type activities. Work is being performed or scheduled by City and Town staff or contractors under the MOAs. On April 5, 2017, the City’s contractor removed two pedestrian bridges over Colma Creek - one closed bridge near Antoinette Lane, and another seldom used bridge in the Orange Park area. Both bridges were removed without incident (see pictures below). - 6 - District staff attended the pre-construction meeting with the contractor and was present during the actual work because of coordination through the TAC.
