1 Zone 4 Report to the Zone Commissioners By Jason Uhley, General Manager-Chief Engineer November 2018 Current Construction Projects Sunnymead MDP Line B (aka Heacock Channel), Stages 3 and 4 ( , -04) This project has been a collaborative effort between the District, March Air Reserve Base (MARB), March Joint Powers Authority (MJPA) and the City of Moreno Valley. The project is located along the west side Heacock Street between Cactus Avenue and Perris Valley Channel Lateral A, and will replace two miles of an existing undersized earthen ditch. Stage 3, shown in purple, and Stage 4, shown in green, would improve this earthen channel to an ultimate 100-year concrete facility and provide flood protection for future healthcare facilities, federal properties and more than 130 residences and businesses in the city of Moreno Valley. The District is funding the construction for Stage 3 improvements. The District has also agreed to construct Stage 4 with funding from the Air Force Reserve Command of $7.6 million. The project was awarded on July 12, 2017 to Sukut Construction, LLC at the lowest bid price of $13,591,604. Construction began in February 2018 and is now near completion. 1

2 Capital Improvement Plan Projects San Jacinto River, Stage 3 ( ) This is a District-led project to develop a master drainage plan along the nearly 10-mile reach of the San Jacinto River from Ramona Expressway to Railroad Canyon. The goal of the plan is to provide flood protection to critical transportation facilities, alleviate drainage concerns in the city of Perris, advance implementation of the Western Riverside Multiple Species Habitat Conservation Plan and accommodate certain land development activity within the floodplain fringe. On April 11, 2017, the Riverside County Board of Supervisors accepted the Conceptual Planning Report and directed the district to proceed on the Master Drainage Plan (MDP). Subsequently, the District executed a consulting services agreement on May 22, 2018 with a contract value of $343,800 with Albert A. Webb Associates for the MDP and necessary environmental compliance documents. The District anticipates approval of the MDP and environmental documents by June San Jacinto River, Stage 4 ( ) This project, a joint venture with the City of San Jacinto, was conceived as a multi-stage plan to construct the ultimate levee system (approximately 1,200 feet river bottom width) between the existing Corps levee 9,500 feet upstream of State Street and a point about 8,200 feet downstream of Sanderson Avenue a distance of about five miles. 2

3 Beginning in 2001, the parties have entered into a series of agreements covering the cost share and reimbursements for a project to mitigate the San Jacinto River flood hazards, the last being the Cooperative Agreement, dated February 9, 2010, for the San Jacinto River Levee, Stage 4 Project to provide for new flood control facilities extending for the existing Corps of Engineers levee to a point about 6,000 feet downstream of Sanderson Road. In the Cooperative Agreement, the respective parties each committed up to $12 million to fund project engineering, construction and right of way acquisition. After 2014, the District and the City recognized that project cost estimates would exceed their individual funding resources and that affected property owners would need to participate in a funding mechanism to acquire project right of way, which led to City attempts to reach option agreements with the affected property owners. However, on June 19, 2018, the City Manager informed the City Council that after 6 months of discussion, the affected property owners had declined to participate in a financing district to cover the cost of the right of way acquisition. Without this commitment by the property owners there would be a $5 million shortfall. Since the District and the City do not have the funds to meet the shortfall, the Council, on recommendation from the City Manager, moved to request the District to modify the existing funding agreement and remaining balance of its $12 million commitment to other flood control projects that would benefit residents and public facilities within City limits and anticipate entering into subsequent cost share agreements for those projects. The District will proceed to salvage the time and work invested in the project with finished plans, secured permits and FEMA floodplain revisions that reflect the current condition. 3

4 Bautista Creek Channel - Recharge Basins ( ) This project is a partnership between the District and Lake Hemet Municipal Water District (LHMWD) to expand the groundwater recharge within District-owned land adjacent to Bautista Creek Channel. The project will utilize 17.5 acres of open space to construct six sub-basins that will be interconnected with the existing basins to the south. During wet weather, additional storm flows will be able to be diverted from the channel to allow for natural percolation in the new sub-basins. During dry periods, surplus water will be piped into the new basins through a proposed 18-inch waterline. The District will construct the project, with LHMWD assuming responsibility for the operation and maintenance of the project. The District and LHMWD have executed a cooperative agreement and are currently finalizing the license agreement to outline the operation and maintenance responsibilities of each agency. The District is currently finalizing the 60% plans and addressing the Corps' comments on the 408 alteration permit for the existing Bautista Channel and Levee adjacent to the project area. San Jacinto MDP Lines E-2 and E-2A ( ) This is a City of San Jacinto-led project to provide flood protection to properties along State Street. The project consists of an underground storm drain that will collect 10-year storm runoff at Menlo Avenue and convey it north to the existing San Jacinto Line E improved channel. The District executed a funding agreement with the City of San Jacinto and City of Hemet on August 29, 2017, and will contribute $1.6 million toward design and construction of the project. The Cities of San Jacinto and Hemet will fund the remaining portion of the cost. In September 2018, the District sent redlined comments regarding potential utility conflicts. The City is expected to finalize the plans and submit for District approval in November. 4

5 Green Acres Dam and Outlet ( ) The proposed District-led project consists of a dam that will help reduce flooding over areas located south of its location near the intersection of Cortrite Avenue and Los Limones Lane in the Green Acres area. The preliminary size of the dam includes a maximum height of about 50 feet and a maximum storage volume of 204 acre-feet. The District has completed a feasibility study which included a preliminary geotechnical investigation to assess the feasibility of constructing a dam at the proposed project site. The feasibility study concluded that the site is suitable for dam construction. Right of way acquisition for a portion of the site is underway. Additional preliminary design work and additional soil exploration is currently planned to be able to secure DSOD (Division of Safety of Dams) endorsement for the project early in the design process. Lakeview/Nuevo MDP - Lateral D ( ) The proposed District-led and funded project will provide an outlet for Lakeview Dam and interim collection of local flows along Water Avenue. The project will construct an underground pipe starting at Lakeview Dam and continue westerly along Water Avenue and 11 th Street prior to discharging into the existing Nuevo Channel facility. Design mapping, preliminary environmental assessment and the Preliminary Design Report have been completed. Project design is anticipated to begin in the first quarter of

6 Sunnymead Line M-11 Extension/ Flaming Arrow ( ) A City of Moreno Valley-led project to capture runoff that is flooding properties along Saint Christopher Lane, this project consists of a storm drain which will extend from Bay Street north and west to Saint Christopher Lane. The District is performing the design and funding construction that will be performed by the City. The City is responsible for the environmental permits, rights of way, ordering the relocation of utilities, construction, operation and maintenance of the storm drain. Final plans are in progress and are anticipated to be completed at the end of Moreno Line F-2 & F-18 ( ) This City-led project was budgeted to increase the capacity of the existing Moreno MDP Line F-2 within Redlands Boulevard to convey the 100-year flows and to include the addition of Line F-18 that will capture flows in Alessandro Boulevard between Merwin Street and Redlands Boulevard. The City has since proposed to change the scope of the project to include Line F-18 and Line F-19 and deleting improvements to Line F-2. The District is currently finalizing an agreement with the City to help fund their design and construction costs. 6

7 Romoland MDP Line A-3, Stage 2 ( ) This District-led storm drain project is the third phase of the three construction phases of Romoland MDP Line A and Homeland MDP Line 1 systems. The Line A-3 system extends north of the railroad line at Mathews Road to Valera Lane, where it heads east to Malone Avenue. However, due to difficulties in acquiring right of way north of Highway 74, this project will be built in stages. Only the reach of storm drain along Palomar Road south of Highway 74 (shown in red) will be designed and constructed at this time. The District expects to have 60% design plans completed by the end of June

8 Sunnymead MDP Line B-16A ( ) This is a District-led project in the city of Moreno Valley that will reduce flooding problems along Kitching Street and the surrounding community. Line B-16A will collect runoff from Kalmia Avenue and convey it south along Kitching Street in an underground storm drain which discharges to an existing storm drain at Ironwood Avenue. Implementation of the project may also reduce erosion and sediment accumulation along Kitching Street. Currently, the City is investigating right of way acquisition for the private properties on Kitching Street. Coordination with the City regarding right of way acquisition and street improvements is ongoing. A project charter is expected to be finalized with the City by the end of January Sunnymead MDP Line H-1A, Stage 3 ( ) This City-led project was awarded to O'Duffy Bros, Inc. in June 2017 and completed in June The project began at Ironwood Avenue and consists of underground storm drain in Hubbard Street with an upstream terminus at Kalmia Avenue. The project intercepts flows along Hubbard Street and conveys them south to the existing storm drain in Ironwood Avenue. The District provided $1,380, to the City to cover the full cost of the construction contract for the storm drain. The District is now working with the City to accept portions of the project for ownership, operation and maintenance. 8

9 Moreno-Alessandro Interim Facility (Discovery Church) ( ) A City of Moreno Valley-led project, designed and funded by the District to minimize the sedimentation problem that is affecting the Discovery Church property. The project will convey storm runoff to an underground storm drain that will take runoff under Alessandro Blvd. and into an interim open channel. Flows will continue southerly in the open channel and outlet into the existing Moreno MDP Line H-2, Stage 1 system at Brodiaea Ave. Construction of the interim facility will help reduce the sedimentation problems in smaller storm events until the ultimate master drainage plan storm drains can be constructed along this same alignment. The District is currently working on 90% plans with an anticipated delivery of the completed project design to the City by the end of Moreno-Cottonwood Interim Basin ( ) A City of Moreno Valley-led project designed and funded by the District, this project will capture sediment from an eroding wash to help prevent flooding of a downstream neighborhood cul-de-sac on Cedar Court. Pursuant to a cooperative and funding agreement, the District completed the design and provided funding for the construction, and the City obtained the rights of way and environmental permits. The City of Moreno Valley completed the construction of the project summer

10 Moreno MDP Line K-1 ( ) and Line K-4 ( ) In order to improve the floodplain and reduce flood risk to adjacent homes, this City-led project will construct an underground storm drain that will collect the 100-year storm flows in Locust Avenue (Line K-4) and Carrie Lane, Kalmia Avenue and Pettit Street (Line K-1) to an outlet just south of Juniper Avenue. The City has initiated the design process, and the District has completed its review of the project hydrology and 35% plans. A cost share agreement originally executed in 2014 will need to be updated to reflect District budgeted funding levels and to address ownership, operation and maintenance responsibilities. Perris Valley MDP Line E ( ) This City-led project involves the construction of an open channel on the north side of Ramona Expressway to alleviate flooding at the intersection of Ramona Expressway and Perris Boulevard, and serve as an outlet for existing storm drains that have been constructed in the area. The project will collect runoff in the vicinity of Brennan Avenue and convey it eastward to Perris Valley Channel at Oleander Avenue. The total project cost is estimated to be more than $9 million. The District is providing partial funding toward the overall project using approximately $3.5 million of Area Drainage Plan funds. Remaining funds necessary for the project are being secured by the City. West Hemet MDP Interim Options Evaluation ( ) The City of Hemet has proposed construction of a network of storm drain facilities that would resolve recurring flooding problems near Seattle Street in the city of Hemet. The District has earmarked funds to assist the City with refining their proposal and identifying interim measures that can help address the problems near Seattle Street. A scope of work was prepared by JLC Engineering under contract with the City and includes Seattle Basin improvements, groundwater infiltration, water quality treatment and other improvements to reduce local flooding. This scope will be added to the ongoing Hemet Valley MDP update contract. Uncategorized/Other Contributions Hydrogeotechnical Analysis ( ) This is a District-led project to hire geotechnical engineers to test existing District facilities for groundwater recharge potential. This is fully funded by the District. As of October 2018, four basins in Zone 4 were tested for infiltration and two are eligible for stormwater/urban runoff capture. Miscellaneous Watershed Protection Projects ( ) These projects include resources allocated to the identification and development of potential partnerships for future multi-benefit projects addressing flood hazard reduction, water conservation, water quality and/or other water resource needs. 10
