Welcome and Meeting Purpose

• Michael Bessette, Flood Protection Manager

• Description and Overview of the West Sacramento Levee Improvement Program (WSLIP)

• Program Partners include: USACE, DWR, CVFPB, MBK Engineers, HDR Engineering, ICF, Kleinfelder, KSN Engineering, NHC, David Ford

• WSAFCA: City of West Sacramento, RD 900, and RD 537

Flood Risk Awareness• Communities throughout the Central Valley are at Risk to

Flooding

• National Flooding Events (2005 - present): New Orleans, Fargo ND, Midwest, Iowa, Tennessee, East Coast

• Flood issues have national attention (e.g., understanding risk, floodplain management, level of protection, insurance requirements, levee design criteria, climate change effects, flood protection responsibility)

• West Sacramento Takes Action on Flood Protection

City Actions

• City Council makes Flood Protection No. 1 Priority• City Management Focus on Flood Protection, Selects

and Contracts with Consultant Team• WSAFCA Successfully Passes Proposition 218

Election (70%) – assessment on property• City Council Passes Ordinance on New Development• City Approves Sales Tax Extension Targeted toward

Flood Protection• In Process of Establishing Planned Development

Overlay (levee protection zone)

Program Objectives

• Achieve a minimum of 200-year level of flood protection for the entire City (City Ordinance)

• Prioritize and select levee reaches for improvement• Construct levee improvements as quickly as possible

to reduce flood risk (State EIP Program)• Identify opportunities to work with local and regional

partners to complete work efficiently and economically

• Achieve Congressional Authorization for the WSLIP

Program History

• Recent Flood Protection Efforts– 1990-1993: $9 million in repairs to Southport levees

– 1999-2002: $32 million in repairs on Sacramento and Yolo Bypass levees

– 2006: 2 levee sites repaired by DWR

– 2007/08: WSAFCA and DWR Conduct levee evaluations

– 2008: I Street Levee Improvement Project Completed

– 2009: Slip Repair Completed on Yolo Bypass Levee

– 2009/10: Levee improvement designs underway

Study Area

• 50+ miles of levees protecting the City

• Levees divided into nine study reaches

• 17 miles along the Deep Water Ship Channel also being evaluated

• City divided by Deep Water Ship Channel

Planning Process

• Problem Identification – locating and scoping deficiencies (2007/08)

• Alternatives Analysis – matching potential improvements to address the deficiencies (2008/09)

• Environmental Documentation – evaluating possible environmental effects from the potential improvements (2009/10)

• Estimated Total Construction Cost = $460 million

Alternatives Analysis –Possible Improvement Measures

• Raising the existing levee• Constructing an adjacent or setback levee• Slope flattening• Seepage berms or stability berms• Cutoff walls• Levee drains and relief wells• Stone protection• Removing non-compliant vegetation

Early Implementation• Sites are under evaluation for early implementation

projects (EIPs) to quickly reduce flood risk and are selected based on criteria including:– greatest improvement in public safety with least negative effects

– Env. concerns, permitting, real estate, and availability of funds

– integration of multipurpose objectives

• First EIP completed in 2008 (I Street Bridge Site)

• Three EIPs for 2011/2012 construction– CHP Academy site (2011)

– The Rivers site (2011)

– Sac Bank Extension site (2012)

CHP Early Implementation Project

• 6,300 feet of Sacramento Bypass South Levee

• Install cutoff wall under levee crown

• Correct waterside levee slope

• Install access road with pavement and access

controls for bicyclists and pedestrians

Rivers Early Implementation Project

• 3,100 feet of Sacramento River levee adjacent to Bryte Park

• Install cutoff wall under levee crown• Install access ramps and road with pavement for

bicyclists and pedestrians, turnstile at River Crest Dr.• Install paved pathway along south edge of riparian

vegetation, connecting Rivers trail and river overlook• Continuing study of extension of levee improvements

through Rivers subdivision
