Why use a Street Corridor? Lot Grading and FG Surface • A single base model drawing that contains: • Link to Centerline Profile Design • Link to other Street Model surfaces • Workspace for Curb and Gutter designs • Street Corridor vs Site Corridor Model • Smaller drawings • Simplified corridor parameters list • Low Risk of Corruption – “Diversified” portfolio • Isolated editing environment for multiple project team members Street B Surface Street C Surface Street A Corridor and Street A Surface FG Centerline Design Profile (Street A) Profile View Base Showing 3 Line Profiles Curb and Gutter Surface Profiles from Corridor (Street A)
7 Steps to Building the Detailed Street Corridor include: • Street, Crown & Gutter Alignments • Preliminary Point Grading • Crown & Gutter Profiles and Featurelines (Warps) • Baseline and Region Parameters • Corridor Surface • Data Shortcuts • Plan n Profile Referencing and Production
