View Corridor Analysis
Definition
View corridor analysis identifies and protects sightlines to valued landmarks—mountains, monuments, waterfronts—by modeling what can be seen from specified vantage points. It combines high-resolution terrain and 3D building data with proposed developments to test whether structures intrude into protected cones. Policies then regulate heights, setbacks, and massing to preserve public views while accommodating growth.
Application
Cities use corridor analysis in downtown plans, waterfront redevelopment, and historic district guidelines. Developers iterate designs to fit within envelopes; tourism and cultural agencies protect iconic vistas.
FAQ
How do you define a corridor fairly?
Use transparent criteria—origin points, angular width, vertical extents—and public consultation; map alternatives and justify the chosen envelope.
What data quality is required?
Accurate building models and terrain; small vertical errors can change conclusions. LiDAR and verified BIM geometries are preferred.
How to handle trees and seasonal foliage?
Model deciduous and evergreen differently; treat trees as soft obstacles with seasonal opacity if policy allows some partial screening.
How can corridors coexist with density goals?
Shift height to adjacent zones (transfer of development rights), require step-backs, or define view windows rather than continuous bans.
