SECTIO N 1 "A land development regulation that fosters predictable built results and a high-quality public realm by using physical form (rather than separation of uses) as the organizing principle for the code... It is a regulation, not a mere guideline." Form -Based Code Institute -! Conventional Zoning vs. FBC A General Approach Comparison f Conventional Zoning Certainty and Predictability 0% 100% • Focuses on the separation of uses and is nearly silent on physical form and character. Is silent about walkable neighborhoods and centers. • Uses blunt tools like Density + FAR, offering low predictability. • Constantly, needs high amount of negotiation to determine eventual outcomes Iowa City — Form -Based Code and MMH OPTICOS Form -Based Coding Certainty and Predictability i 100% • I Is focused on physical form + character and the public realm. • Is specifically for walkable neighborhoods and centers. C L Uses actual building elements + terminology tailored to the community's expectations. More upfront work to establish standards but then doesn't need negotiation to determine eventual outcomes Conventional Zoning vs. FBC Future Land Use Map Conventional Zoning • A map that assigns the allowed uses and maximum height. oPTICOS Form -Based Coding A map that assigns the code's zoning districts and various standards to physical locations and individual parcels.
