Small project
stormwater
plan
(MR 1-5)
Small projects are required to meet Minimum Requirements 1-5.
These projects are generally less impactful and therefore require less
stormwater protection and mitigation efforts. These projects have
the option to use the City’s pre-engineered worksheets, templates,
and forms to construct an a Small Stormwater Management Plan.

Large Project
Stormwater
Plan
(MR 1-9)
Large projects are required to meet all Minimum Requirements
(1-9). These projects are either impactful by design or are being
developed in an environmentally sensitive and/or critical area. The
project proponent is required to retain professional engineering
services to prepare and submit a detailed report that addresses site
specifi c stormwater concerns and engineered solutions that meet
WA State specifi cations.
