In an earlier post I discussed the concept of Transfer Development Rights (TDRs) and how this concept is being used in an unusual way in Black Diamond - where both sending and receiving areas are located within an Urban Growth Area (UGA). Typically, rural or areas outside of a UGA deemed needing protection from long term development are the sending areas. UGA's become the receiving areas. While I still remain a bit confused about Black Diamond's TDR program, King County's overall TDR program is more illustrative of what we typically see with Transfer Development Rights and their benefits. Thanks to Lisa Parsons, MGRC Executive Director (and for full disclosure, I am also a Board member of MGRC), I have been able to learn more about King County's TDR Program. The following map outlines both the sending and receiving areas within the County.
The concept basically is to preserve open space in rural or other environmentally unique areas and concentrate growth within defined Urban Growth Area (UGA) boundaries. It's a concept long championed by the Cascade Land Conservancy and they have done much to preserve and protect critical areas from development around the state - I am a strong supporter of their mission and organization. As you can see from this graphic and as you would expect, urban areas such as Seattle, Des Moines, Federal Way, Kirkland, Redmond, Bothell etc are the receiving areas. Sending areas are largely rural.
What caught my attention as I looked more closely was that there were 4 specific areas directly adjacent to our community here in Black Diamond Diamond that were within defined receiving areas. What?
My first learning was that there are several areas within King County, but outside of Black Diamond, that are designated as within UGA boundaries. Given the history of the BDUGAA and much more, why would King County be designating areas within unicorporporated King County as UGAs? This makes no sense to me, but then I have learned that history is indeed a mystery. King County is not in the business of providing urban services. Four developments directly adjacent to our city but just outside of city limits have been designated as within our UGA. Go figure. In addition, four developments received TDR's, have expanded their density. Take a look at the following map.
These developments include Alders Cove and Kentlake Highlands and each has been increased in density (more lots) as a result of the County's TDR program. In time, particularly given the state of King County finances, I wouldn't be surprised to see annexation pressures increase, with police protection being a key driver. Unmitigated traffic impacts have already been incurred. Following is a summary of the impacts on our UGA already built:
Adding 26 lots to a 397 acre development may in the end not be too big a deal. But, I can find no logic for the County adding such density in unincorporated King County where the County is in no postition to provide the urban services required. Hopefully, the preservation earned in return has been worth it. TDR's provide an important tool for preserving land and managing growth smartly. However, the two local examples I have seen thus far do make me question whether or not the program is being implemented wisely.
