The AHMP updates the County's long-term affordable housing goals and objectives, first adopted 15 years ago. The proposed Plan reflects 3 years of data-gathering, needs analysis, and community outreach by an 18-member citizen working group and County staff to address Arlington's housing needs and ensure economic sustainability through 2040. (The new Plan when adopted becomes part of the State-required County Comprehensive Plan, integrating housing, energy, and transportation planning, among other elements.)
Don't be confused by misstatements about what the AHMP does.
The AHMP is a policy document---a set of goals and objectives---that will be implemented over the next 20 years or so. It is not a commitment to specific building sites or spending. (In fact, it contains language that allows for review/revision as conditions dictate. And, as is the case now, spending on housing will be determined through the annual budget process.)
The IF describes existing and potential tools (financial, land use/regulatory, and services) that might be used to achieve Plan goals. (Any new or revised tools will require additional research, development, and deliberation, with opportunity for public input.)
