Demolition, grubbing (removing material from the project site such as soil, pavement or vegetation), and grading (changing the surface of the ground) generally are the first activities that occurs during construction. Typically, the following requirements are needed before demolition, grubbing, and/or grading:
- Installation and approval of erosion and sediment control Demolition, grubbing (removing material from the project site such as soil, pavement or vegetation), and grading (changing the surface of the ground) generally are as outlined in the Stormwater codes SMC 22.800-22.808; and
- Providing a survey to establish the designed elevations of the sub grade or surface of the improvement.
Excavating and placing soils may also require soils to be transported to an acceptable disposal site and/or importing soils from an approved source.
All work in the right-of-way, including demolition activities must be conducted with minimum impacts to existing trees; refer to Section 4.14 Street Trees and Landscape Architectural Standards and any other existing infrastructures.
