Wassermann Lake Preserve
Overview
When the Minnehaha Creek Watershed District and the City of Victoria rebuilt Wassermann Lake Preserve — restored prairie, oak savanna, and shoreline on Lake Wassermann — they wanted the park itself to teach. Dimension Sign won the district's direct RFQ and fabricated the entire interpretive family in quarter-inch weathering steel: an illuminated entry monument whose waterjet-cut oak canopy glows after dark, three double-faced interpretive hubs with full-color printed maps reading through the cut steel, and a trail's worth of sculptural elements — a 45-mile Watershed Walk, rolled-steel prairie oaks, wetland reading rails, a legacy-oak fire shield, and a lake chime.
01 / The challenge
Interpretive work asks steel to do things sign cabinets never do. Every piece in the landscape architect's vision carried a rolled-top, rolled-bottom profile in quarter-inch plate. The hub panels had to marry full-color printed maps to raw weathering steel — roads and labels cut clean through the face, registering exactly over the print behind. Typography had to survive being cut through: every font converted to stencil forms so the counters wouldn't drop out, every long river cut engineered with micro-breaks so the panel stayed structurally sound. And the whole family had to land in a two-day install window inside an active park construction site, complete with a 3,000-pound boardwalk load limit.
02 / Our approach
We cut everything flat on the waterjet — through-cuts for copy and roads, dashed cuts for watershed boundaries, shallow etching for contours and tree canopies; three techniques on a single panel — then had the plate formed by a metal-rolling specialist and welded, gusseted, and finished it in-house. The featured Watershed Connection panel carried some ten hours of waterjet time alone; behind its cut face floats a digitally printed exterior-grade HPL map of the Six Mile Creek–Halsted Bay subwatershed on welded standoffs, proofed at full size so every cut road landed on its printed twin. The entry monument hides a programmable, waterproofed fixture behind a translucent panel — the oak canopy glows at night — with a piano-hinged Corten face for service access. Down the trail, welded stainless mile-marker rings pace ten-foot ribbons tracing Minnehaha Creek's 274-foot fall from the headwaters to the Mississippi, and rolled-steel oaks stand embedded five feet deep in concrete.
Steel that glows after dark
The entry monument is a lightbox wearing quarter-inch weathering steel. Behind the waterjet-cut oak canopy sits a translucent white diffuser and a programmable, waterproofed fixture, so the branches burn warm against the rusted face all night. One full Corten face swings open on a piano hinge for service — and the finished electrical connection was made by our crew and inspected and accepted by the city's maintenance staff before we left the site.
- Waterjet-cut canopy backed by a translucent diffuser
- Programmable, waterproofed fixture inside the steel cavity
- Piano-hinged Corten face — serviceable without unbolting a panel
- Burned in at the shop before delivery
