North site looking southeast: pre-demo conditions
North site looking southeast: after demo of existing soils and stream channel, excavation for animal pond, partial installation of drainage system
North site looking southeast: subgrades with installation drainage system and shotcrete boulder cages
North site looking southwest: subsurface drain pipe with area drain, access hole through perimeter concrete wall for continuation of drain pipe to catch basin, existing piping to protect and work around, typical area requiring 100% of work by hand due to no equipment access
North site looking south: grade stakes and conditions after installation of sands and soils, crushed rock animal path, animal pond with tie-in to drainage system, new stream channel tie-in to existing stream channel
North site looking southeast: finished site showing all protection removed, crushed rock animal path, shotcrete boulders, stream channel and animal pond, and final developed seeding prior to reintroduction of tigers and other animals into exhibit

South site looking southwest: finished conditions showing new shotcrete surfacing tie-in to existing surfacing, crushed rock animal paths, and final developed seeding prior to reintroduction of tigers and other animals into exhibit

Located at the Point Defiance Zoo this very unique project was within two different and separated areas on site. This project involved complicated pedestrian protection and very long material haul routes. Site work included detailed surveying, demo of almost all existing surfaces, and installation of intricate drainage systems. Finish work included large shotcrete animal-perch boulders, pathways with stair systems, tie-in to existing shotcrete stream channel, animal access paths, irrigation, and seeding.
