About this file
This file is a helical pier layout plan prepared by JVA Inc., a consulting engineering firm based in Boulder, Colorado, for the Walden Ponds Accessible Fishing Pier & Boardwalk project in Boulder County, Colorado. The document, dated July 27, 2026, provides detailed technical specifications and dimensional drawings for the installation of helical pier supports designated as HP12, which are designed to support 2x8 beams and joists with 4x4 blocking aligned with each joist. The plan indicates specific measurements and spacing requirements, including 5-foot intervals and 2x8 joists spaced at 16-inch centers, with helical piers positioned to support the reconstructed fishing pier structure. The project address is listed as 3893 North 75th Street, Boulder, Colorado 80301, and the drawing is identified as S101 with job number 260292.STR, drawn by LB and AB.
This layout plan is part of the reconstruction effort for the Wally Toevs Fishing Pier following a structural failure in July 2025 when support posts shifted, causing deck joists to separate from the ledger board and resulting in partial collapse. The Boulder County Parks and Open Space Department solicited bids from structural engineering firms to redesign both Walden Ponds structures and provide construction documents. A qualified helical pier specialty contractor is being procured to complete the design submittal and installation of the helical pier supports. The pier has remained closed to the public since the incident, and construction is scheduled to begin as soon as finalized plans are available, with this project taking priority given the severity of the original structural failure and the need to ensure compliance with modern ADA requirements.
