The Expanding Housing Options proposal focuses on adding homes where sewer, water, stormwater, and other infrastructure systems are already available and have capacity to accommodate more homes. Allowing modest home types like accessory dwelling units or duplexes in existing neighborhoods means new construction will be at a small scale, and will be spread out over a wide area, so no single system is overwhelmed. This kind of slow and steady growth can be carefully planned for. Routine monitoring can detect capacity issues in advance, and give engineers and planners time to adjust if anything changes in the future.
