Two separate canopies in one city. The pre-1960 blocks around Old Town and near County Line Road hold Greenwood's only genuinely mature shade trees — just 9% of the housing stock predates 1960 — while the subdivisions east of I-65 are 2000s-era plantings still small enough to prune off a ladder. Ash is functionally gone: emerald ash borer has been confirmed in Indiana since April 2004 and is now in all 92 counties. That context matters for silver maple: silver maple is the most over-planted large tree in indiana's street tree population — roughly 18% statewide and about 14% of indianapolis street trees — because it was the default fast shade tree in subdivisions built from the 1950s through the 1970s. Removing a silver maple around Greenwood runs roughly $400–$1,900, and in Old Town Greenwood, Green Valley and Imperial Hills access is usually what decides where in that range you land.
What's actually growing in Greenwood
Two separate canopies in one city. The pre-1960 blocks around Old Town and near County Line Road hold Greenwood's only genuinely mature shade trees — just 9% of the housing stock predates 1960 — while the subdivisions east of I-65 are 2000s-era plantings still small enough to prune off a ladder. Ash is functionally gone: emerald ash borer has been confirmed in Indiana since April 2004 and is now in all 92 counties.
Greenwood's housing stock, and what it means for tree size
Median year built is 1996 across 27,721 housing units (ACS 2019-2023, tables B25034/B25035). About 27% predates 1980 — including a small pre-1940 Old Town core — but roughly 42% went up after 2000. The practical result: 70-to-90-year-old shade trees hanging over Old Town roofs, and 10-to-20-year-old nursery stock in the subdivisions east of I-65.
What's specific to silver maple
Ice is the killer, because the architecture is long, horizontal, and end-weighted, so a quarter inch of glaze puts enormous bending moment on the union. Silver maple typically does not uproot — it splits vertically down a codominant stem or tears a whole scaffold limb out of the trunk, peeling a strip of bark with it, which is the exact failure that lands on roofs in central Indiana ice events.
Johnson County rules
No permit is required to remove a tree on private property in Greenwood. Tree rules in the city code are all about new development and the public way: the UDO's landscaping standards require street trees along frontage and give credit for preserving existing large-caliper trees, separate provisions restrict planting in the public way, and the Stormwater Department's Easement Encroachment Permit is required before planting any tree or shrub inside an existing drainage or utility easement. The specific UDO section numbers and planting ratios could not be verified against the live code — confirm with Planning and the Stormwater Department. Cutting down your own backyard tree needs nothing.
