| 1 | # Zoning and Codes Skill |
| 2 | |
| 3 | This skill provides comprehensive zoning analysis and form-based code generation capabilities for urban design and masterplanning projects. It covers the full spectrum of zoning approaches from conventional Euclidean zoning through transect-based SmartCode, and provides detailed workflows for translating design intent into enforceable regulatory language. The skill draws from the SmartCode, Miami 21, Denver Form-Based Code, and international best practices in development regulation. |

| 7 | ## 1. Zoning System Types |
| 8 | |
| 9 | Use the following comparison matrix to select the appropriate zoning approach for a given project context. Each system has distinct strengths and is suited to different planning objectives. |

| 11 | ### Comparison Matrix |
| 12 | |
| 13 | | Type | Primary Controls | Strengths | Weaknesses | Best For | |
| 14 | |------|-----------------|-----------|------------|----------| |
| 15 | | **Euclidean** | Use categories (residential, commercial, industrial) + dimensional standards (setback, height, lot size, FAR) | Simple to administer; predictable outcomes; well-understood by developers and communities; extensive legal precedent | Rigid separation of uses enforces automobile dependence and sprawl; does not address building form or public realm quality; encourages lowest-common-denominator development | Stable suburban areas; low-density residential neighborhoods; industrial zones; contexts where predictability is the primary goal | |
| 16 | | **Performance** | Impact metrics (traffic generation, noise levels, shadow/daylight access, stormwater runoff, air quality emissions) | Highly flexible; focuses on outcomes rather than prescriptions; encourages innovation in design solutions; can accommodate unforeseen uses | Complex to administer and enforce; requires technical expertise for review; unpredictable physical outcomes; challenging for community members to understand | Mixed-use areas where impact matters more than form; transitional zones between incompatible uses; innovation districts; areas with complex environmental constraints | |
| 17 | | **Form-Based** | Building form (height, setback, coverage, FAR), frontage types, building types, public space standards | Produces predictable physical form and high-quality public realm; enables mixed-use by right; regulates what matters most to communities (physical character); illustrated and accessible | Requires design expertise to draft and administer; less familiar to many planning departments; can be perceived as overly prescriptive for building design; initial adoption requires education | New development and infill projects; downtown revitalization; transit-oriented development; areas where physical character is the primary concern; urban renewal zones | |
| 18 | | **Transect-Based (SmartCode)** | Rural-to-urban gradient zones (T1-T6) with calibrated standards for each zone; integrates thoroughfare, civic space, and building standards | Holistic and context-sensitive; addresses the full range of human settlement patterns; internally consistent; treats urbanism as an ecology; comprehensive framework | Requires paradigm shift from conventional zoning thinking; initial calibration to local context is labor-intensive; may not fit jurisdictions with highly irregular development patterns | Comprehensive plan implementation; greenfield master-planned communities; complete code replacements; jurisdictions ready for a fundamentally different approach to regulation | |
| 19 | | **Hybrid** | Combination of two or more approaches (e.g., form-based for downtown + Euclidean for suburban residential + performance for industrial/environmental overlay) | Balanced approach; can tailor regulation to distinct character areas; pragmatic; easier political adoption by preserving familiar systems where they work | Can be complex to navigate; risk of internal contradictions between systems; may confuse applicants moving between zones with different regulatory logic | Most real-world applications; jurisdictions transitioning from Euclidean to form-based; cities with diverse character areas requiring different regulatory approaches | |

| 21 | ### Selection Decision Tree |
| 22 | |
| 23 | 1. Is the project a comprehensive code replacement for an entire jurisdiction? --> Consider **Transect-Based (SmartCode)** |
| 24 | 2. Is the project focused on a specific plan area (downtown, corridor, TOD)? --> Use **Form-Based Code** for the plan area |
