design guidelines for the vieux carrÉ historic district wins the commission excellence award

July 29, 2016

On Friday, July 29, 2016, the National Alliance of Preservation Commissions [NAPC] honored New Orleans' Vieux Carré Commission and Dominique Hawkins of PDP with a Commission Excellence Award in the category of "Best Practices" for its Design Guidelines for the Vieux Carré Historic District.

The almost three century old Vieux Carré is a National Historic Landmark containing approximately 2,000 properties and 3,000 structures. Its preservation is dependent not only upon regulating exterior changes to the resources in the district's built environment, but also on educating a wide range of individuals, particularly property owners, on how to preserve and maintain the historic structures in the district. The Design Guidelines accomplish both objectives.

PDP is selected for the colemantown meeting house flood mitigation and limited restoration project

July 29, 2016

The Jacobs Chapel Colemantown Foundation, Inc., selected PDP, with the technical team including Keast & Hood Co. [K&H], Bruce E. Brooks & Associates [BBA], and Irving Design Group, LLC, [IDG], for the flood mitigation and restoration project. The primary objectives are to mitigate further accelerated deterioration of the building fabric from storm water runoff, structurally stabilize the building, and provide barrier-free accessibility and facilities. To achieve these goals, the scope of work must include raising the building by sixteen inches, regrading the site, and repairing framing. 

As noted in the Preservation Plan prepared by Westfield Architects & Preservation Consultants, "Jacob's Chapel A.M.E. Church and the Colemantown Meeting House and Colemantown Cemetery are significant for their representation of the growth and development of free African American communities in New Jersey during the nineteenth century as a result of the enactment of the 1804 "Act for the Gradual Abolition of Slavery" and the permanent abolition of slavery in the state in 1846. The two buildings and cemetery are all that remains of the nineteenth-century enclave of Colemantown, which housed free black people as well as runaway slaves who had found freedom and settled in New Jersey..."
