A July 29 Baltimore Sun article discusses the complexity and challenges of a Howard County land preservation deal to preserve a significant portion of the estate and manor of Charles Carroll, a signer of the Declaration of Independence.  Some county residents also objected to the deal, which relies on a mix of development and preservation agreements.

A plan to cluster development in one corner of historic Doughoregan Manor while preserving the rest of the once-vast Colonial estate received final, unanimous approval from the Howard County Council late Thursday.

The complex plan would provide more than $19 million over two decades in agricultural preservation money to Camilla and Philip D. Carroll, descendants of Charles Carroll of Carrolton, a signer of the Declaration of Independence. …

Under the plan, 325 homes can be built on 221 acres in the northeastern corner of the estate, near Frederick Road and west of Centennial Lane. The Carrolls would give 36 acres to Howard County to more than double the size of Kiwanis-Wallas Park on Frederick Road. The rest of the land will be preserved.

To accomplish all that, the County Council approved extending water and sewer utilities onto the development portion of the property, and also approved adding 500 acres of farmland to the county’s Agricultural Preservation program, under which the Carrolls will be paid over the next two decades.
