2012 LID Technical Guidance Manual for Puget Sound



The 2012 LID Technical Guidance Manual for Puget Sound 

WSU Puyallup Research & Extension Center and the Puget Sound Partnership are pleased to announce the 2012 LID Technical Guidance Manual for Puget Sound.  The new manual incorporates new information and results of recent research regarding the LID approach and techniques appropriate to the Puget Sound region.  To download the new manual, please see the link below.  Due to state budget cutbacks, we are unable to print hard copies of the manual.  For more information about the revision process, please see below.  For more information about the content of the manual, please contact Curtis Hinman at chinman@wsu.edu.  For more information about the revision process, please contact Bruce Wulkan at bruce.wulkan@psp.wa.gov or Curtis Hinman.

Stakeholder Review of Updated LID Guidance Manual

The draft 2012 LID Technical Guidance Manual for Puget Sound was available for stakeholder review and comment from January 9 – February 15, 2012. Thank you to all regional professionals who submitted comments (see below for list of commenters, table showing on-line comments submitted, and additional comment letters submitted). Due to state budget reductions, we had limited resources for a stakeholder review and the number and extent of comments exceeded our estimates and available resources. We reviewed all comments received and have addressed as many comments as possible at this time. Some comments simply cannot be addressed at this time due to insufficient information and/or data – we hope to address more of these comments through future research and future updates as more information becomes available.

We will announce the availability of the new manual on this web site and through regional professional groups, such as the APWA Stormwater Managers Committee, the Municipal Phase I and II Coordinator’s Groups, the Washington Stormwater Center, and the Stormwater Monitoring Work Group.  
 
Please see below for the draft 2012 manual and additional information about the update process.

February 2012 Draft LID Technical Guidance Manual for Puget Sound

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 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 now scheduled to be available to the public November 1, 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 – August 2012
  • Development of graphics: September 2010 – August 2012
  • External Review: January - February 2012
  • Compilation and incorporation of comments: March – July 2012
  • Layout: August – October 2012
  • Release copies: November 1, 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 released a complete draft of the manual with images in January 2012, and solicited input from regional stakeholders. We thank the many professionals who took the time to read the draft and review draft graphics and provided us with their thoughts. See above for list of commenters, table of on-line comments received, additional comment letters received, timing for release of the final manual, and other key information.

Funding

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

WSU Extension Puyallup contributed significant in-kind staff time to this effort. U.S. EPA Region 10 also provided additional funding, under a National Estuary Program agreement, for design and layout of the manual.

If you have questions about the project, please don’t hesitate to contact Curtis Hinman at chinman@wsu.edu or Bruce Wulkan at bruce.wulkan@psp.wa.gov.
