Description of Addendum
This addendum issued per WAC 197-11-625 is required to alter the recorded final plat of Mirror Lake
Highland. The city has received an application to eliminate the note on the Mirror Lake Highland plat map
that requires affordable housing on Lots 7 and 13. All of the plat infrastructure is constructed, and
individual homes have been constructed on all of the lots in Mirror Lake Highland except Lots 7 and 13. No
changes to the environment will occur with this proposed action. The only proposed change is to eliminate
the affordable housing requirement on the plat for the two remaining lots (numbers 7 and 13). The proposed
action to eliminate the affordable housing requirement for Lots 7 and 13 is consistent with the current
Federal Way Revised Code (FWRC). On November 4, 2020, the Federal Way City Council via ordinance
20-899 eliminated the previous requirement in FWRC 19.250.150 titled: affordable housing bonus in RS
zoning classifications.
A DNS was issued on April 16, 2008, for the original preliminary plat proposal and no SEPA mitigation
was required. No appeals were submitted to the city on the original DNS. A SEPA addendum is necessary
for the proposed alteration of the recorded Mirror Lake Highland final plat.
No new or substantially different environmental impacts are anticipated. The proposal will result in two
middle-income housing units rather than two affordable housing units, consistent with current FWRC 19.250.
NOTE: There is no comment period for this addendum per WAC 197-11-625.
