The shoreline and river environs overlay district is designed to protect the water quality of Payette Lake and the North Fork of the Payette River, as well as the aesthetic views. McCall is known for its natural scenic beauty, which generates tourism and recreation in the area. One reason for the ordinance was to protect this economic resource by protecting viewsheds and fish and wildlife habitat. The most significant part of the ordinance establishes a 50-ft development setback from the lake and river, which helps protect the water resources, and has a positive aesthetic effect on the environment. The ordinance also requires plans for stormwater and meltwater facilities.
