The Dalles City Council and Planning Commission discussed the draft of a housing production strategy at a Thursday evening joint meeting.  It was the third in a series of joint meetings on development of the state-required strategy.  Consultants Cascadia Partners presented a group of 19 different actions primarily aimed at encouraging and stimulating the production of affordable and middle-income housing.  Lydia Ness of Cascadia Partners said one of the key actions in the list is to adopt a multi-unit partial property tax exemption to incentivize construction of needed housing types, and there is flexibility in how to do it.  Another point of discussion was a 1% construction excise tax to generate revenue to put toward affordable housing.  City Manager Matthew Klebes noted staff time would be a key factor in being able to develop some of the recommendations.  Another Planning Commission worksession on the topic is planned in November, with a final draft to be complete by December 15 for potential Council adoption in January.
