The document discusses creating preserves along the Portage Escarpment ravines in Euclid, Ohio to protect the local streams and greenspace. It notes that the ravines have escaped development due to steep slopes. The preserves would help reinvigorate nature in Euclid by acquiring vacant, tax-delinquent parcels along the ravines and legislating to keep the areas free from building. This would protect local waterways and Lake Erie while providing ecosystem services. Specific ravines that could become preserves are discussed.
