Woodland Park Zoo West Entry

Part of a long-range physical development plan, the new main entrance for Woodland Park Zoo replaces two smaller entrances at the north and west sides of the park. The 112,490 square foot entry area contains 8,274 square feet of buildings – ticketing facilities, a new membership service facility, a new zoo retail store, restrooms, and a visitor assistance facility; and continues the Zoo’s commitment to sustainable operations and LEED certification.

Sustainable highlights of the project include: energy-efficient building design; covered bicycle parking; low-flow toilets; high-speed, hygienic hand dryers that use 80 percent less energy than warm-air hand dryers; exterior siding made from Forest Steward Council-certified wood; and more than 48,000 square feet of enhanced native plant landscaping, featuring 80 new trees to increase the overall zoo canopy. Additionally, the rainwater infiltration system built for the new entrance prevents the runoff of approximately 975,000 gallons of storm water a year, reducing the chance of overflow from the combined sewer system into local waterways including Puget Sound. Ultra-low flow fixtures should reduce potable water use by about 45 percent of code. On the construction side, the project features high amounts of recycled content and regional materials; and earned an exemplary performance point for recycling over 95 percent of the construction waste.

O’Brien & Company worked as LEED Project Manager for the design team from design development through LEED certification and provided LEED documentation assistance to the contractor. Beginning with a review of green features in the design and developing plans for LEED certification, O’Brien & Company played a key role in getting the details of LEED credits fully documented. Examples include devising a method for documenting three separate mechanical systems in one LEED project, allowing clarity for the LEED Reviewers to award the credit, and tracking down the details for the recycled and regional materials credit. As a result the new Woodland Park Zoo West Entry received LEED Gold certification in early 2011.
