Five Rivers MetroParks Boundary Guide: Nearly 16,000 Protected Acres, the 33-Acre Woodman Fen Inside Kettering, and the Survey, Tree, Deer, and Easement Rules for Homes That Border Park Land

Five Rivers MetroParks is the park district for all of Montgomery County, Ohio, and it protects nearly 16,000 acres of open space across 18 MetroParks and more than a dozen conservation areas, with about 3,000 additional acres held under permanent conservation easements. When your property borders that land, the practical questions are concrete: where the survey line actually sits, who can trim a tree that overhangs it, what the deer-management program means for your yard, and whether an easement on the next parcel restricts what happens there. This guide answers each one with the district's own published rules and Ohio law, with a source and an access date for every figure.

The boundary between your lot and a park is a property line like any other: it is set by deed and survey, enforced by whoever owns each side, and settled by the county recorder's records, not by a fence that has stood for years. The difference with a MetroPark is that the owner on the other side is a public agency that manages its land for conservation and enforces its own code. In our experience helping buyers and sellers in the Miami Valley work through homes that touch Five Rivers property, the survey and the tree questions are where deals most often stall. Here is what we check before an offer.

What Is Five Rivers MetroParks, and How Much Protected Land Sits Next to Montgomery County Homes?

Five Rivers MetroParks was created in 1963 and is an independent political subdivision of the State of Ohio formed under Ohio Revised Code Chapter 1545 (Park Districts). It is governed by a three-member, volunteer Board of Park Commissioners appointed by the Montgomery County Probate Judge, and it serves Dayton and every city and township in Montgomery County. The district reports protecting nearly 16,000 acres of open space, about 90 percent of it kept in a natural state, across 18 MetroParks, roughly 11 conservation areas, the 2nd Street Market, and regional recreation trails.

Funding explains a lot of how the district behaves as a neighbor. Five Rivers gets most of its revenue from voter-approved property tax levies, about 93 percent as of 2025. On November 5, 2024, Montgomery County voters passed Issue 35, a new 1.0-mill, 10-year levy designed to work down a $58 million backlog of repair and replacement projects across the district's 35 locations while it continues acquiring and managing natural areas. That levy context matters to a home buyer because the district's ability to enforce boundaries, manage deer, and buy buffer land is funded by the same countywide tax base that your property tax bill supports.

Which Five Rivers Parks and Conservation Areas Border Residential Neighborhoods?

Several Five Rivers properties sit directly amid or alongside residential streets. Woodman Fen Conservation Area is a 33-acre groundwater-fed fen at 2409 Newcastle Drive in Kettering, purchased in 2003 and surrounded by houses, with the Iron Horse Trail running along its northern border. Cox Arboretum MetroPark on Springboro Pike in Miami Township is enveloped by the residential subdivisions of Kettering, Washington Township, and Miami Township near the Dayton Mall, and the park's own history notes that in the early 1960s development surrounded the pastures of the former farm that would have become a housing tract. Englewood MetroPark, Carriage Hill MetroPark and Huffman MetroPark in Huber Heights, Sugarcreek MetroPark on the Sugarcreek Township and Bellbrook line, Possum Creek MetroPark in Miami Township near West Carrollton, and Taylorsville MetroPark in Vandalia all sit within or against residential communities. Farther south, Germantown MetroPark and Twin Creek MetroPark anchor the Twin Valley Conservation Corridor.

The conservation areas are the most likely to have a residential backyard on the other side of a tree line, because they are significant natural tracts with minimal infrastructure. Table 1 lists the conservation areas with published acreage and addresses, plus the communities they border. Where the district has not published an address or acreage, the table says so rather than guessing.

Conservation area	Acreage	Location / entrance	How it borders homes
Woodman Fen	33 acres	2409 Newcastle Dr., Dayton / Kettering 45420	Rare groundwater-fed fen inside residential Kettering; Iron Horse Trail along the north border; purchased 2003
Medlar	417 acres (416 per district map)	4558 Medlar Rd., Miami Township, south of Miamisburg	Added December 2010; open farmland and habitat bordering township and village residential areas
Spring Run	550 acres	2765 N. Snyder Rd., Dayton 45426 (Trotwood)	Two parcels: 360-acre Great Miami Mitigation Bank and 190-acre former Larch Tree Golf Course; adjacent to the 2,384-acre Sycamore State Park
Dull Woods	8 acres	8199 Cole St., Brookville 45309 (Clay Township)	Small wooded tract along the Wolf Creek Trail in northwest Montgomery County
Needmore	160 acres	Three tracts along the Great Miami River north of Dayton, near Needmore Rd.	River floodplain tracts adjacent to residential and park land between Dayton and Old Troy Park
Pigeye, Sandridge Prairie, Shiloh Woods, Twin Valley (Upper Twin)	Acreage not published in sources reviewed	Englewood area; bluff prairie; Montgomery County; Twin Valley Corridor	Pigeye is planned to become part of Englewood MetroPark; verify parcel lines on the district's interactive map

Reporting note: names, acreage, and addresses from Five Rivers MetroParks park pages, the What We Protect page, and the interactive parks map, accessed October 2026. The district publishes acreage and street addresses only for its enhanced-access areas; the rest are listed without published figures rather than guessed.

Do I Need a Survey If My Yard Touches a Five Rivers Property?

Yes, and it is the first practical step, because the district actively manages and enforces its own property line. Five Rivers operates under a published Code of Rules and Regulations and a Code of Ordinances: Title XIII, Chapter 131 of the code makes unauthorized entry onto park land, or placing structures on it, a matter of criminal or aggravated trespass under Section 131.03, and Section 131.11 bars injuring or removing vines, bushes, trees, or crops on park property. A fence, shed, patio, or driveway that crosses onto district land is an encroachment the district treats seriously, so a current survey is how you prove where your line actually is.

One thing a Five Rivers property does not do is impose a private setback on you. The district's conservation priorities include protecting natural areas adjacent to existing MetroParks and river corridors and establishing buffer areas where needed, but it achieves those buffers through its own land purchases and conservation easements, not by mandating how far your deck must sit from the line. Setbacks for new structures come from your municipality's or township's zoning code, so your local zoning department, not the park district, sets the building setback on your side of the boundary.

Can I Trim a Five Rivers Tree That Overhangs My Yard?

Ohio follows the Massachusetts Rule on encroaching branches: you may trim a neighbor's tree branches that overhang your property line back to the line, at your own expense, without the neighbor's permission, as long as you do the work from your own side and do not harm the overall health of the tree. Ownership of a tree follows the trunk, so a tree whose trunk sits on Five Rivers land is the district's tree even when half of its canopy hangs over your yard.

The limits are real. You may not trespass onto park land to reach the branches, you may trim only back to the property line and not beyond, and if the trunk straddles the line the tree is co-owned and both owners must consent to significant pruning or removal. Ohio Revised Code 901.51 makes it a fourth-degree misdemeanor, with treble damages available in a civil case, to recklessly cut down, girdle, or otherwise injure a tree on another person's land. Because the tree is on public park land, the practical move is to call the district first: Five Rivers takes property-line questions at (937) 567-4265 and general questions at (937) 275-7275, and written approval before you prune avoids a dispute over a public tree.

Situation	The rule	What a homeowner should do
Park tree branches overhang your yard	Massachusetts Rule: self-help trimming to the property line at your expense, from your side, without harming the tree	Call the district at (937) 567-4265 for written approval before pruning a public tree
Trunk straddles the property line	Co-owned tree; both owners must consent to significant pruning or removal	Get the district's agreement in writing before any major work
Cutting or injuring a tree on park land	ORC 901.51: fourth-degree misdemeanor plus possible treble damages; district Code 131.11 bars injuring plants and trees on park property	Never cut, girdle, or top a tree you cannot prove is on your side of the line
Fence, shed, patio, or driveway near the line	Structures on park land are unauthorized encroachments under Code Chapter 131	Survey first, keep every improvement fully on your side, and note setback rules from your zoning code
Who decides a boundary disagreement	The deed, the recorded survey, and the county recorder's records decide the line, not a long-standing fence	Pull the survey and parcel records from the Montgomery County Recorder before closing

What Are the Deer, Dog, Hunting, and Burning Rules Near Park Land?

General public hunting is not allowed on Five Rivers land, with one managed exception. The district runs a Controlled Bowhunting Program as part of its deer population management, alongside ranger culling. For the 2026-2027 season, 146 registered applicants were randomly drawn to qualify; each qualified hunter must hold a valid Ohio hunting license and deer tag, pass an orientation, and demonstrate marksmanship, with the district's standard being at least 4 of 5 arrows inside a 10-inch target at 20 yards. There is a $20 registration fee, and harvested venison is donated through Farmers and Hunters Feeding the Hungry. Critically for neighbors, the district states that all hunting is located away from trails and adjacent properties, so it is not running in the tree line behind your backyard, and it cites increased development on adjacent land as a cause of high deer numbers in the first place.

Dogs are welcome on the trails but must stay on a leash no longer than 8 feet and under your immediate control, per the district's published abbreviated rules. Fires are allowed only in grills or designated areas, and bringing firewood into MetroPark facilities is prohibited. The rules apply on the park side of the line, but they matter to owners because the reservation is often the trailhead, the view, and the deer corridor all at once.

Rule	What it means on the ground	What a homeowner should do
Hunting on park land	No general public hunting; only the Controlled Bowhunting Program for deer management, sited away from trails and adjacent properties	Do not assume park-adjacent land is huntable; deer work is done by qualified, permitted archers
Dogs on park land	Must be leashed no longer than 8 feet and under your immediate control	Keep the leash at 8 feet or less at every trailhead, including the one off your own yard
Fires and firewood	Fires only in grills or designated areas; bringing firewood into facilities is prohibited	Use park grills as posted and never move firewood between sites, a step tied to invasive-pest control
Deer presence near homes	The district links high deer numbers to increased development on adjacent land and manages them scientifically	Expect deer near the tree line; the program is active and year-round, not a no-wildlife zone
Encroachment onto park land	Unauthorized entry or structures on district land are addressed under Code Chapter 131	Survey before building anything near the line and keep every improvement on your side

What Are Conservation Easements, and Can They Restrict Land Next Door?

Five Rivers protects more than 3,000 acres through conservation easements, and its largest concentration is along Twin Creek: roughly 1,711 acres of private land surrounding Twin Creek MetroPark and Germantown MetroPark, part of the Twin Valley Conservation Corridor, completed in partnership with the Three Valley Conservation Trust. A conservation easement is a permanent legal agreement in which a private landowner keeps ownership of the land but permanently gives up the right to develop it. The owner can keep farming, forestry, recreation, and other green-space uses, and can sell or transfer the land, but the restrictions run with the title and the trust regularly monitors the property to enforce them.

The key point for a home buyer is that an easement on a neighboring parcel does not restrict your land, but an easement on a parcel you are buying does bind you. A five-acre field under easement next to your subdivision can stay open forever, which is often a genuine amenity, but you have no legal right to develop it either. Before an offer, your title commitment's Schedule B exceptions are the place to spot easements of record, and the Montgomery County Recorder's office holds the recorded documents if you want the exact restriction language.

How Do Property Taxes and Levies Factor Into Park-Adjacent Ownership?

Living next to a MetroPark does not set your property tax rate; taxes follow the county auditor's appraisal of your parcel and your community's millage. The district's levies are countywide, so every Montgomery County property owner, park-adjacent or not, pays toward Five Rivers through the same property tax bill, currently including the 1.0-mill, 10-year levy voters passed in November 2024. What is worth a specific check is the appraisal on your own parcel through the Montgomery County Auditor, because park-adjacent homes with mature trees and protected views sometimes appraise differently than interior lots in the same subdivision, and only your parcel's real numbers matter at closing.

For buyers, the practical checklist is the same as for any parcel with a long property line: confirm the survey, read the title commitment's Schedule B for easements and right-of-way exceptions, verify the community's millage and the exact parcel's tax bill through the auditor, and get any fence or tree question in writing before you sign. This is general education about park rules, Ohio property law, and market data, not legal, tax, title, or financial advice; consult a qualified attorney, your title company, and your lender for your specific transaction.
