What: A voluntary density bonus in the housing zoning package that would replace an expanded mandatory inclusionary zoning requirement. Developers get bonuses in exchange for 10 to 20 percent affordable units, at no more than 50% of area median income for rentals and 80% for owner-occupied units, with an optional payment in lieu of $25 per square foot. The Planning Commission's condition sets a 20-year affordability period, against 35 years under the existing mandatory overlay; several speakers and Councilmember Warwick urged at least 35 years.
