198 (Proposed modification includes the addition of 18 lots)
Under Review
Case Numbers:
PDR2018-00005/ TUP2018-00022 thru 00026.

Applicant Materials: Residential Planned Development Detailed Plan Review | Five Temporary Use Permits | Early Grading Authorization

Background: The city approved plans for the subdivisions known as River Terrace Crossing in 2017. However, Polygon Northwest notified the city that it was their intention to modify the original approvals to allow the developer the ability to refine the lot layout to offer a housing variety that better suits the current housing market.  The request proposes to introduce a single-level home option and replace large lots for more standard and medium lots that are more affordable. The proposed modification includes the addition on 18 lots which remain in compliance with the allowable density range originally approved with the development.  Plans have been submitted to the city for review in December 2018. A public hearing on the new plans is scheduled for March 4th, 2019.
