Public Comments Received from Toyer Strategic Advisors

Letter to SCT Planning Advisory Committee

Letter to SCT Community Advisory Board (CAB)

Letter to SCT Steering Committee, County Officials and County Council Members

Responses to Toyer Strategic Advisors (these responses are incorporated into the Draft Buildable Lands Report recommended by the SCT PAC on June 10, 2021):


  • PDS staff reviewed all the comments provided and have either addressed or incorporated the suggested changes that were made.  Our responses to each suggested revision are indicated in the right-hand column labeled “RESPONSE” in the 1st PDF document available via link below.
  • Note that a large number of the suggested revisions were the result of the different definition for pending development than is used in the BLR.  The 2nd PDF file below describes the current definition of pending development that is used for the 2021 BLR (and past BLRs), and how it differs from the approach advocated by Toyer Strategic Advisors.
  • The remaining suggested edits were reviewed by PDS staff and a number of edits were made to the critical areas data and land status classifications in response to comments.  You will see those noted under the “RESPONSE” column.
  • When the suggested revision was located within a city, PDS staff worked with city staff to gain their input on whether the suggested revision should be made to the BLR data.  In those cases, the notations under the “RESPONSE” column reflects city input.

Remaining Schedule for Finalizing the 2021 Buildable Lands Report


The purpose of the BLR is to review the urban densities that are being achieved within both the city and county portions of the Urban Growth Area (UGA) and, based on the densities achieved, determine whether the UGA has an adequate supply of suitable residential, commercial and industrial land to accommodate the population and employment growth projected to occur during the remaining portion of the 20-year GMA planning horizon. If not, jurisdictions are required to take corrective actions (reasonable measures) that do not include adjustment of UGA boundaries.

According to the Snohomish County Countywide Planning Policies, the BLR is prepared by cities and the county using the Snohomish County Tomorrow (SCT) collaborative process. For the BLR, the county has the lead role in preparing the report, with the cities providing key data input and review responsibilities. SCT has published three BLRs on behalf of the county and its cities; one each in 2002, 2007, and 2012. See below for links to these previous BLRs.

In the 2017 session, the state legislature passed E2SSB 5254, which enacted a number of changes to state requirements for buildable lands methods and procedures. Subsequently, the Washington State Department of Commerce published updated Buildable Lands Program Guidelines in December 2018. County staff have been working with the cities, consultant staff, and stakeholder representatives on developing recommendations for implementing these changes in the 2021 BLR.
