Since 2007, Sierra Planning has provided architectural and civil engineering design and drafting support in California and Oregon

Site, Grading & SWPPP Plans


Depending on your need, we will start with a Site Plan Submittal to your municipality.  If your project is residential, we will prepare a plot plan as needed.  We prepare grading plans and will handle any NPDES Storm Water Pollution Prevention Plans and Erosivity Waivers.

Residential Additions


We can provide 3D conceptual design as well as drawings so you can pull a permit.  Depending on your addition, you may find its easier to start building than you imagined.

Drafting Outsourcing


We can augment an existing company's drafting personnel by preparing construction documents for overflow projects.

Additionally, many times a property owner or builder have existing paper drawings and need them redrawn to CAD using industry layer standards. Call or email us for a free quote.
