95-foot observation tower construction closes main trail at Mentor Marsh

At the height of summer, the main trail at Mentor Lagoons Nature Preserve was closed for construction of a 95-foot observation tower overlooking Mentor Marsh — trading the preserve's most direct route for a promised view from above. The closure was scheduled through Aug. 16. Only the main trail was affected; the city's notice did not indicate that other trails in the preserve were closed.

The city published conflicting start dates: an earlier notice said the closure began Tuesday, July 28, 2026, while a later notice published Aug. 19 said it ran from Friday, July 31, 2026, through Sunday, Aug. 16, 2026. Mentor Lagoons Nature Preserve, at 8365 Harbor Drive, has more than three miles of hiking trails open from dawn to dusk.

The tower represents a $1.8 million bet on eco-tourism infrastructure at the city-owned preserve. Mentor Lagoons sits on the western boundary of Mentor Marsh State Nature Preserve, a 691-acre wetland recognized as a National Natural Landmark in 1966 as one of the most species-rich sites on the Great Lakes shoreline and designated as Ohio's first state nature preserve in 1971. The marsh is one of the largest remaining natural marshes on Lake Erie's shoreline, providing breeding and nursery habitat for fish, supporting waterfowl and migratory songbirds, and serving as a major migration stopover for birds and butterflies.

City materials have described the structure as both 92 and 95 feet tall — May 2025 voter materials referred to 92 feet, while July 2026 construction notices use 95 feet. The tower is planned for the marsh rim, approximately 1,000 feet north of the preserve's main trailhead. It will have a 25-foot-by-25-foot top deck and an ADA-accessible elevated platform offering panoramic views of Mentor Marsh, nearby uplands, and Lake Erie, enhancing wildlife viewing and access to the marsh.

The Cleveland Museum of Natural History manages Mentor Marsh State Nature Preserve and has led restoration efforts. The City of Mentor owns and operates the 450-acre Mentor Lagoons Nature Preserve, including the adjacent marina, on the state nature preserve's western boundary.

Mentor voters authorized the tower on May 6, 2025, approving Issue 4 by a vote of 471 to 142, or 76.84%. The ballot language asked: "Shall Ordinance No. 25-0-017 approving the construction of an observation tower within the Mentor Lagoons Nature Preserve with the assistance of grant funding be approved?" Under the Mentor city charter, voters must approve capital improvement projects within Mentor Lagoons Nature Preserve. City materials said the tower would be indefinitely tabled and grant dollars rescinded if Issue 4 failed.

"It has taken a little while to reach this stage," Ken Filipiak, city manager of the City of Mentor, said. "We had to work through some agreements with the Ohio Department of Natural Resources," Filipiak said.

Mentor City Council approved the approximately $1.8 million construction contract on Jan. 20, 2026, awarding the work to Great Lakes Crushing Ltd. of Willowick. The $1,837,159 award included the base bid plus alternate 2. The project includes $450,000 in Ohio Department of Natural Resources grant funding. The contract specified a construction timeline of approximately 270 days after notice to proceed, with completion targeted for fall 2026. The preserve already has a 442-foot ADA-accessible boardwalk, added in 2022, that connects to the main trailhead.

The larger question surrounding the project remains unresolved: whether the nearly $1.4 million in city funds committed beyond the $450,000 state grant will genuinely broaden public engagement with the marsh's ecology or add a destination feature that prioritizes views over the quiet stewardship that has sustained the preserve for more than five decades.
