As a part of the Delta Levee Investment Strategy DLIS the six urban levees in the Delta were evaluated based using ULDC. APPENDIX A HYDRAULIC DESIGN REPORT OUTLINE 4-13 APPENDIX B EXAMPLE PROJECT CHECKLIST FOR HYDRAULIC DESIGN 4-15 Chapter 5 - Planning and Location 51 INTRODUCTION 5-2 511 Preliminary Planning 5-2 512 Flood Hazards 5-2 513 Construction Problems 5-2 514 Maintenance Problems 5-3 52 CRITERIA 5-3.

Phase 1 included all non-urban levees and consisted of review and assessment of available.

. The criteria for encroachments are described in ULDC report Section 712 criteria for penetrations are described in Section 713 and criteria for closure structures are described in Section 714. Urban Levee Design Criteria. The first phase consists of data collection field visits and a desktop assessment of existing conditions and past levee performance.

These factors include the soil profile of the area strengths of the foundation materials slope stability settlement and trafficability of the levee surface. 17 for urban areas called the Urban Levee Design Criteria ULDC May 2012 which describes the 18 levee and floodwall design criteria which flood control facilities protecting urban levees must 19 now meet. The Urban Levee Design Criteria ULDC provides engineering criteria and guidance for the design evaluation operation and maintenance of levees and floodwalls that provide an urban level of flood protection ie 200-year level of flood protection in California as well as for determining design water surface elevations DWSE.

Two-Phase Approach As depicted in Figure 2 the NULE project was conducted in two phases. Non-urban levees protect populations of fewer than 10000 people. Non-urban levees are those that protect fewer than 10000 people.

30 URBAN DESIGN CHALLENGES FOR SITES WITH DRIVE-THROUGH FACILITIES. Includes Urban Levee Evaluations Project classifications. Section 31 page 3-4 Table 3-2 Notes 3 and 4.

It is noted that the Star Bend Setback Levee Project is. 20 The ULDC provides engineering criteria and. Within an Urban Criteria Area the fence would also need to be constructed beyond twenty 20 feet from the landside Levee Toe unless the area meets requirements for the Board to allow for the fence either to be constructed beyond ten 10 feet.

The Urban Levee Design Criteria ULDC provides engineering criteria and guidance for the design evaluation operation and maintenance of levees and floodwalls that provide an urban level of flood protection ie 200-year level of flood protection in California as well as for determining design water surface elevations DWSE along leveed and unleveed streams. Engineering and Design DESIGN AND CONSTRUCTION OF LEVEES 1. DWR may also include the Urban Level of Flood Protection Criteria in future requirements for determining eligibility for grants.

Were performed based on criteria presented in the Department of Water Resources Urban Levee Design Criteria ULDC dated May 2012. Urban Levee Design Criteria. Criteria and if appropriate to identify remedial measures to improve levees to meet those criteria.

2 2016 ULOP Adequate Progress Report West Sacramento Area Flood Control Agency 20 PURPOSE AND NEED. State guidelines as presented in the State of California Department of Water Resources DWR Urban Levee Design Criteria 2012 will also be referenced. The levees are currently accredited to FEMA standards per 44CFR 6510 and the cities desire to achieve an Urban Level of Protection ULOP by 2025.

This 45 million project is being performed in two phases. Of compliance with the Urban Levee Design Criteria ULDC in the record following the EVD-1 procedure in the California Department of Water Resources DWR Urban Level of Flood Protection ULOP Criteria for the Star Bend Setback Levee from Station 695 to 5000 Setback Levee Stations. The Urban Levee Design Criteria ULDC provides criteria and guidance for designing evaluating operating and maintaining levees and floodwalls in urban and urbanizing areas.

3 Includes all small communities within the SPFC Planning Area. Establishing standards and criteria for the design of sites with drive-through facilities integrating operational elements site and built form design with a focus on assisting this use with making a positive contribution to the surrounding context and pedestrian streetscape. These standards are known as the Urban Levee Design Criteria ULDC and provide specific engineering criteria for levees.

In designing a levee a contractor must consider numerous factors based on the individual project. In 2016 FHWA reduced the original 13 criteria to the following 10 criteria that are considered by FHWA as controlling for the design of projects. And Urban Levee Design Criteria apply to a limited set of Urban Areas and Urbanizing Areas identified within this definition.

Of levees as presented in USACE Engineering Manual 1110-2-1913 Design and Construction of Levees USACE 2000 based on the requirements of 44CFR6510. The purpose of this manual is to present basic principles used in the design and construction of earth levees. Design Speed Lane Width Shoulder Width Horizontal Curve Radius Superelevation Rate.

Categories Marginal and Does Not Meet Criteria and Non-Urban Levee Evaluations Project categories B Moderate and C Low. Levees not meeting the program criteria are identified and prioritized for further. This manual applies to all Corps of Engineers Divisions and Districts having responsibility for the design and construction of levees.

It is necessary to define Urban Levee Design riteria to establish that it has the same meaning as the Levee and floodwall design criteria developed by the Department for providing the Urban Level of. 1 Project Levee A levee or flood wall that is a facility of the State Plan of Flood Control as defined in Public Resources Code Section 5096805. 2014 to analyze the RD 17 levees utilizing the State of California Urban Levee Design Criteria ULDC and to identify deficiencies and countermeasures.

2 As defined in the Urban Levee Design Criteria DWR 2012 frequently loaded levees are defined as levees that experience a. Policy guidance and design criteria describes the progress that the City and WSAFCA have made toward achieving an urban level of flood protection for the City. ENGEO performed a geotechnical exploration and levee evaluation in accordance with the 200-year level of flood protection Urban Levee Design Criteria ULDC for the RD-17 levees.
