Consider for recommendation to the Board of Commissioners approval to apply an opaque sealant on all cast stone elements of the building, including window surrounds, tracery, pier caps, and coping.

On September 23, 2019 the Historical Commission recommended approval subject to review by a subcommittee.  On October 1, 2019, the subcommittee of the Historical Commission met on site and recommended approval subject to:

a) Application of Conproco M3P semi-opaque stain on all cast stone elements, with final color match to be approved by staff.

b) Application of Conprolastic film-forming waterproofing products on all new or deteriorated original or replacement elements, color matched to the M3P stain to be approved by staff.

The Commission recognizes that both products will detrimentally change the aesthetic of the original cast stone elements, eliminating color variation, contrasting aggregates, and pointed joints within the stonework, but feels the Commission is providing a compromise to address the water infiltration issues with the building envelope, and view this as a unique condition particular to this property.
