Information for Presenters

Submission and Staff Review

Once a project is submitted, Landmark Preservation staff works with the applicant to ensure that the project meets the design guidelines, the materials are complete and to write a staff report and create a presentation for LPC members that includes a recommendation of approval, approval with conditions, or denial for the project. Because this process takes several weeks, complete submittals must be received at least four weeks prior to a commission meeting date to have a chance to make it onto that agenda.

Agendas are capped at a certain number of projects. Projects with complete applications are added to the agendas on a first come first served basis, and once an agenda is full, projects are scheduled for the next available LPC meeting. Please note that when we receive a high volume of projects, specific dates are not guaranteed.
