Some developers purport that projects proposed for the district's parcels, developed and undeveloped, are substantially exempted from the environmental review provisions of the California Environmental Quality Act(CEQA) because they are considered "infill" parcels. In other words, CEQA has a special provision for streamlined environmental review for infill projects located in urban areas of Oakland. Conversely, some activists have pointed to the applicability of the "Cumulative Impact" provisions of CEQA arguing that the residents of the neighborhood have already been subjected to several consecutive years of construction, dust, pile-driving and general construction noise, and carcinogenic diesel fumes from idling trucks and heavy equipment.
