Treatment Guidance This section provides recommendations for the preservation and repair of Pearl Street Mall. Treatment guidance applies to the entirety of Pearl Street Mall. This guidance should be followed when undertaking design and planning for Pearl Street Mall or when proposing modifications to contributing features, existing features and to qualities that contribute to Pearl Street Mall’s historic character, including proposals for new development within the landmark boundary. Treatment guidance is presented according to seven landscape characteristics — spatial organization, circulation, structures, objects, small-scale features, vegetation and views and viewsheds. Spatial Organization Pearl Street Mall is a linear space, extending from building facade to building facade for four city blocks, composed of a central urban corridor flanked by a defined space (clear of features or plantings) at each building edge. Each block includes art, play and gathering nodes set with the central urban corridor. • Protect Pearl Street Mall’s composition by preserving and repairing its characteristic pattern of a central urban corridor with defined spaces at building edges and its nodes of art, play and gathering. • Preserve Pearl Street Mall’s views to the Boulder Flatirons from the westernmost block. • Ensure new additions or modifications to existing features and vegetation respect, and do not interfere or diminish Pearl Street Mall’s composition or views. Circulation Pearl Street Mall is characterized by a consistent ground plane of brick paving that assists in orchestrating pedestrian movement and uses. Limited vehicular routes are allowed within specific areas of Pearl Street Mall. • Protect Pearl Street Mall’s consistent ground plane of brick paving through on-going maintenance, repair and maintenance of paving and spaces. ○ Preserve the characteristic extant three-part repetitive brick paving pattern that extends consistently across all four blocks, including the central herringbone paving pattern. ○ Repair and replace missing or damaged paving with in-kind materials that match the original paving in color, texture and pattern. • Ensure Pearl Street Mall remains as a pedestrian mall by protecting its patterns of circulation and by sensitively integrating delivery, service or access for vehicular uses. • Provide accessible routes within Pearl Street Mall for an equitable experience for all users. Allow designated routes and seating areas, where appropriate and where compatible with contributing features. Ensure accessible routes at street crossings, public buildings and structures including restrooms, and where appropriate, at private business building entrances. Structures Original structures associated with play and gathering nodes remain, and contribute to Pearl Street Mall. Newer structures include vendor facilities, a kiosk and public restroom. • Protect contributing play and gathering nodes in their original locations. ○ Preserve and repair extant features in-place. • Consider new structures to accommodate programming, use and to improve health and safety within Pearl Street Mall, where appropriate. ○ Consider reusing existing sites where non-contributing structures are located, and as improvements, prior to installations in new locations. ○ Consider a master planning process to determine and locate new objects. • Maintain contributing structures through regular maintenance including routine removal of graffiti and posters, and replacement of broken lights.
