Overview

WSU Extension and the Partnership are teaming up again to develop the region’s technical guidance on low impact development (LID).

WSU and the Partnership worked with many excellent professionals throughout the region to develop the 2005 Low Impact Development Technical Guidance Manual for Puget Sound. Many Puget Sound local governments adopted the 2005 manual, and many others use it by reference. Many developers, builders, landscape architects and others also use the manual. Information and images from the manual have been borrowed and used by offices across the nation and around the globe. We are grateful for the 2005 manual’s acceptance, and sincerely hope professionals within and outside the region find the second edition of the manual as helpful and useful.

The new manual is scheduled to be completed in May-June 2012 and will incorporate new information and results of recent research regarding the LID approach and techniques appropriate to the Puget Sound region.

The LID guidance manual is being updated along similar timelines as Ecology’s Stormwater Management Manual for Western Washington. Ecology, WSU Extension Puyallup and the Partnership are working together closely to ensure that the two efforts are coordinated and consistent, as they did for the 2005 editions of the two manuals.

Core Group

A core group is leading the project, comprised of Curtis Hinman of WSU Puyallup Research & Extension Center, Bruce Wulkan of the Puget Sound Partnership, and Ed O’Brien of the Department of Ecology. Curtis Hinman is again the prime author for the manual and Bruce Wulkan is again project co-lead and chief editor. Soundwide Starrfish Consulting have been contracted to facilitate the process and help with multiple aspects of the update. AHBL is developing graphics and the Partnership will do layout and oversee distribution.

Pre-project Survey

Before beginning the project, the core group developed and distributed a brief eight-question electronic survey to over 500 professionals in the Puget Sound region who are involved with low impact development in some capacity. The purpose of the survey was to gain input from users of the 2005 LID manual regarding helpful aspects of the manual, missing elements, and items they’d like the 2011 update to address. The individuals who received the survey included:
All participants of the 2009 and 2010 LID Technical workshops (20 workshops; approximately 500 individuals)

NPDES permit coordinators group

Thanks to the 93 professionals who responded to the survey. Their responses helped shape the initial thinking of the manual revision.

Technical Advisory Committee

A technical advisory committee has been formed to provide input to the core group throughout the duration of the update process. In choosing members, the core group sought a range of professionals with extensive LID technical expertise across several key disciplines: Engineering, local LID implementation, soils, hydrology, modeling, and landscape architecture.
Members of the technical advisory committee:

  • Tracy Tackett, City of Seattle (Local LID Manager)
  • Chris May, Kitsap County (Local Stormwater Manager, ex-LID teacher)
  • Craig Young, Snohomish County (Local LID Manager)
  • Matt Miller, Associated Earth Sciences (Geotech)
  • Bruce Barker, MGS (Hydrologist)
  • Alice Lancaster, Herrera Environmental Consultants (Hydrologic Modeler)
  • Catherine Benotto, Webber Thompson (Landscape Architect)
  • Kathy Gwilym, SvR Design (Engineer)
  • Kas Kinkead, Cascade Design Collaborative (Landscape Architect)
  • David McDonald, City of Seattle (Soil Scientist)
    [Alternate: Howard Stenn, Stenn Design]
  • Mark Buehrer/Colleen, 2020 Engineers (Engineer)
    [Alternate: Chris Webb, Chris Webb Design]
  • Art Castle, Kitsap Home Builders Association (Local LID practitioner)
  • Tim Kurtz, Bureau of Environmental Services, City of Portland (Engineer)
  • Karen Strelioff, Mason Conservation District (Local LID practitioner)

In addition to the technical advisory committee, additional regional professionals with specific LID expertise will be brought in as needed to help write and/or edit sections of the new manual.

Timeline

The 2nd edition of the LID Technical Guidance Manual for Puget Sound is scheduled to be available to the public in Spring 2012. Key dates to note include:

  • Technical advisory committee meetings: June 29, October 7, and December 2, 2010; January 11, March 1, and March 29, 2011. Additional meetings TBD.
  • Researching and writing: August 2010 – December 2011
  • Development of graphics: September 2010 – December 2011
  • External Review: January 2012
  • Compilation and incorporation of comments: February – March 2012
  • Layout: March – April 2012
  • Release copies: May or June 2012

External Review

The manual is being developed by a broad group of regional experts. However, many additional stormwater management professionals need to contribute to the manual’s text and images.

We therefore will release a complete draft of the manual with images in January 2012, and will be soliciting input at that time. If you are interested in and have expertise and experience in LID techniques and projects, we hope you will provide input on the draft manual. We will post the exact timing of the draft release, and the process for providing input, on this site as soon as the details are finalized. We will also announce this information through the APWA Stormwater Managers Group, the Stormwater (Monitoring) Work Group, and the NPDES Phase I and II Coordinators groups.

Funding

Funding for the project comes from the Puget Sound Partnership, as part of the state-funded LID Technical Assistance Program.
