ETL 1100-2-1 CECW-CE / CECW-P Procedures to Evaluate Sea Level Change: Impacts, Responses, and Adaptation 6/30/2014 3/30/2019
ETL 1110-2-565 CECW-CE Foundation Engineering: In-the-Wet Design and Construction of Civil Works Projects 9/30/2006 Provides guidance for planning, design and construction of foundations constructed in-the-wet for civil works structures.
ETL 1110-2-566 CECW-CE Advanced Reliability Analysis of Fatigue Cracking in Horizontally Framed Miter Gates 6/1/2010 6/1/2015 Navigational locks and dams along the nation's inland waterways that are maintained by the U.S. Army Corps of Engineers provide the ability to transport large tonnages of materials and goods efficiently over long distances. Lock miter gates are critical components in this transportation system. This technical letter is to enhance and generalize the previously developed analytical methodology for fatigue crack evaluation with the goal of developing this methodology for miter gate fracture, fatigue, reliability, and repair.
ETL 1110-2-568 CECW-CE Seismic Evaluation Procedures for Existing Civil Works Powerhouses 10/31/2006 To provide an evaluation procedure to be followed to properly assess the seismic performance of existing USACE civil works powerhouses. To identify those powerhouse superstructures that may need remediation to assure that they can continue to provide electrical generation critical to post-earthquake on-site emergency response and to the post-earthquake recovery of communities.
ETL 1110-2-575 CECW-CE Evaluation of I-walls 9/1/2011 6/1/2016 Provides updated technical criteria and guidance for evaluation of existing I-walls.  This guidance is for I-walls designed to provide flood risk reduction from inland flooding, not from coastal storm surges with significant wave and vessel impact loads.
ETL 1110-2-576 CECW-CE Ice-Affected Stage Frequency 5/1/2011 4/30/2016 Provides guidance on the development of ice-affected stage frequency (SF) relationships and includes a literature review of advances made in the last two decades, as well as case studies illustrating the various methods.
ETL 1110-2-577 CECW-CE Use of Spiral Welded Pipe Piles 6/18/2012 6/18/2017 Establishes guidance for expanded use of spiral welded pipe (SWP) piles Corps-wide to include sites having soft soils and low probabilities for seismic shaking and extreme cold temperatures.
ETL 1110-2-583 CECW-CE Guidelines for Landscape Planting and Vegetation Management at Levees, Floodwalls, Embankment Dams, and Appurtenant Structures 4/30/2014 3/30/2019
ETL 1110-2-584 CECW-CE Design of Hydraulic Steel Structures 6/30/2014 6/30/2019 This manual supersedes EM 1110-2-2105, dated 31 March 1993, EM 1110-2- 2701, dated 30 November 1997, EM 1110-2-2702, dated 01 January 2000, EM 1110-2-2703, dated 30 June 1994, and 1110-2-2705, dated 31 March 1994
ETL 1110-3-510 CECW-CE Aviation Complex Planning and Design Criteria for Unmanned Aircraft Systems (UAS) 5/31/2013 5/31/2018 This ETL provides guidance and Criteria for planning and designing and ancillary movement areas that support operations of USA, USAF, US Navy Wheeled/Skid USA presently fielded or has a program of record by 2012.
ETL 1110-3-511 CECW-CE Army Airfield/Heliport Planning and Design Changes 5/31/2014 5/31/2019 This ETL provides US. Army Changes to UFC 3-260-01, Airfield and heliport Planning and Desgin
