* As part of the public process POITRA created and maintained the comprehensive public information website for the I-70 East Environmental Impact Statement (EIS) beginning in 2003. The website was fully duplicated in Spanish as part of the outreach campaign. The I-70 East EIS may result in Denver's first covered interstate highway, which will host a park over the cover section.

SR4 at West Hazelton Avenue Photosimulations

CalTrans, Stockton, California

The SR4 Crosstown Freeway Extension for the San Joaquin Council of Governments, CalTrans and the City of Stockton, continued SR4 from it's previous termination at Fresno Avenue over the Burlington Northern Santa Fe (BNSF) RR to Navy Drive and the Port of Stockton. The project looked at a viaduct option and an Mechanically Stabilized Earth (MSE) wall option.

POITRA was asked to prepare a series of visual simulations to address anticipated visual impact and design concerns from public and local government stakeholders. Photo-simulation was the obvious medium for accurate and convincing presentations.

Roadway level simulations were used because the project team needed to evaluate the aesthetic qualities of each option. The wall alternative would show MSE panel treatments, the viaduct alternative would include bell topped pier columns and box girders, and both alternatives would include landscaping. The Engineer provided photograph required intense work to remove buildings and trees in the path of SR4 which revealed preveously unseen areas beyond.

SR4 Consultant Project Manager

The project was at a very conceptual study level and there was little available to guide the look of wall treatments and landscapeing that needed to appear in simulations. POITRA was asked to develop these elements in the simulation based upon our its experience in urban design.

POITRA modelers constructed an accurate 3D site model for each alternative which included the viaduct and piers, walls, MSE panels and abutments and even markers for proposed landscaping elements.

POITRA relied upon its principal's previous career experience in bridge and highway design to follow design plans and complete the model from concept level plans.

The site models were then camera matched, lighted, rendered and composited with the base photograph to create a visual simulation for each alternative. The final simulations were finished using traditional digital image editing techniques.

POITRA graphic artists designed presentation boards for each alternative. The finished simulations were used in stakeholder meetings. end of article
