Wall Inventory Program (WIP) Overview The National Park Service Retaining Wall Inventory Program (WIP) was developed to quantify and characterize wall assets associated with Park roadways in terms of their location, geometry, construction attributes, condition, failure consequence, cultural concerns, apparent design criteria and cost of structure maintenance, repair or replacement. The WIP program was commissioned at the request of the NPS Washington Administrative Services Organization (WASO), Park Facility Management Division. The program is supported by both NPS WASO personnel and staff from the Federal Lands Highway Division (FLHD) of the Federal Highway Administration (FHWA). Both organizations are equally responsible for the development and management of the WIP program; the FLHD has taken the lead for delivery of field inventories, while the NPS is primarily responsible for integration of WIP data within the FMSS asset management system. Similarly to the ongoing National Park Service Road Inventory Program (RIP), it is the intent of the WIP inventory to periodically reassess retaining wall resources at program Parks to further develop asset management strategies for Park roadways. Although highly focused on the asset management needs and processes unique to the NPS, this inventory and assessment approach should find application within a broader national audience as federal, state and local agencies tackle retaining wall asset issues tied to transportation infrastructure. The WIP reports currently available represent inventory work conducted at 26 national park facilities.
