Topographic Mapping for Pines Rd. and Mission Ave. Intersection
Location: Spokane Valley, WA: Horrocks provided topographic base mapping using a high-definition 3D laser scanner to map the intersection of State Route 27 (SR-27) and Mission Avenue in the City of Spokane Valley. High traffic volumes made access into the travel lanes by field crews unsafe. We succeeded in mapping four to five traffic lanes over approximately 1,000 feet of roadway including determination of existing road right-of-ways. The topographic mapping effort consisted of two field days without traffic interruptions, and we provided maps to the City within 30 days and within budget. The final AutoCAD deliverable was provided to the City and met the City of Spokane Valley’s drafting standards.
