Today, Plainfield's Town Council signed off on a master plan that could turn Echo Hollow into a roughly 2,000-acre nature park, a project town leaders say is big enough to pull visitors from across central Indiana. The blueprint calls for phased development with miles of trails, a nature center, an event center, lodging and camping options, and other amenities meant to strike a balance between outdoor fun and environmental protection. The move pushes forward a long-running effort to convert land the town bought from the Indianapolis airport into publicly owned parkland.
As reported by WISH-TV, the adopted document lays out a step-by-step plan to develop roughly 2,000 acres of town-owned land south of I-70. The Town of Plainfield's park page says the property totals more than 1,928 acres, much of it purchased from the Indianapolis International Airport in 2018, and highlights protections for the federally endangered Indiana bat as a key priority.
What the Plan Would Build
According to the Indiana Economic Development Corporation, the master plan sketches out miles of accessible trails, scenic overlooks and a lake-loop boardwalk, along with a nature center, an event center and a lodge or inn paired with campground and RV accommodations. The state release and related planning materials say the town envisions modern restrooms, public art installations and facilities intended to put Echo Hollow in the same league as Indiana's state parks.
Conservation and the Indiana Bat
Conservation is baked into the master plan, with planners calling out the need to protect wetlands, mature hardwood forests and key foraging corridors for the Indiana bat. Hendricks County Parks traces the site's history as Sodalis Nature Park, while a case study from the National Academies Press details the Indianapolis Airport Authority's long-running Habitat Conservation Program that stitched together a conservation area around the airport, including the land that is now at the heart of Plainfield's plan.
Funding and Next Steps
The town has already tapped state READI funding for early construction, including a boardwalk, and the master plan calls for phased public investment supported by tools such as a potential TIF district to cover ongoing operations and maintenance. The Indiana Economic Development Corporation announcement and the town's planning materials say full buildout will require detailed design work, environmental permitting, staged construction and future council approvals before the big-ticket visitor amenities become reality.
Local Reaction and Challenges
The plan has drawn a mix of excitement and skepticism. Conservation groups raised alarms in 2024 over rezoning and tree clearing on parcels next to the park site, even as consulting firms involved in the effort have cheered the project's renaming and forward motion. The Indiana Forest Alliance documented local opposition to rezoning near Echo Hollow, while engineering firm BF&S published a firm news post highlighting its staff's role in crafting the master plan and celebrating the Echo Hollow name.
With the council's vote, Plainfield has cleared a major policy hurdle. Now town staff have to turn concept maps into actual designs, budgets and construction schedules. Residents can expect the project to roll out in phases, with recurring public meetings and funding decisions as different pieces of the Echo Hollow master plan move from glossy renderings to ground-breaking ceremonies.
