The Euclid Creek watershed is almost unique among Ohio streams in that it contains no agricultural land and is more than 80 percent developed.
The undeveloped land is projected to become built up within the next few decades by light industrial, office, residential, and retail construction.
Residential development is likely to be apartment buildings or clustered townhouses, keeping with a national trend away from single-family homes.
This will put new pressure on the water quality of Euclid Creek.
Cuyahoga County Airport is the largest landowner within the watershed.
Six east branch tributaries travel through, under, or adjacent to the airport's 640 acres (2.6 km²).

About 557.8 acres (2.257 km²) of Euclid Creek's watershed is protected.
This includes the 209 acres (0.85 km²) of the Lower Euclid Creek Reservation and 345 acres (1.40 km²) of the Euclid Creek Reservation.
The combined reservation is one of the most heavily-used parks in the Cleveland Metroparks system.
Weekend use in the summer routinely exceeds park capacity, causing compaction of soil, litter, and illegal dumping.
The Cuyahoga Soil and Water Conservation District owns two conservation easements (totaling 13.8 acres (0.056 km²)) covering the headwaters of Euclid Creek in Lyndhurst and Mayfield.
The city of Richmond Heights owns a conservation easement over the ravine and wetlands of Verbsky Creek, and has imposed an environmental deed restriction over Claribel Creek between Richmond Heights City Hall and Richmond Heights Community Park.

Few wetlands remain in the Euclid Creek watershed.
Notable wetlands exist adjacent to Highland Heights Community Park, at the headwaters of a major tributary of the east branch; the Acacia Reservation; and portions of the floodplain of the east branch.
The health of these wetlands is not known.
