Environmental Impacts / Compliance
Wetlands are impacted for the roadway widening and the construction of water quality/water quantity facilities and will be mitigated off site.
SEPA documention will be completed for the project. However NEPA level supporting documentation will be completed to offset risk of needing a NEPA document under NWP. A Corp permit will be required.

Impacts to Traffic
Single lane and shoulder closures will be necessary to accomplish the following work: paving/striping at 152nd and 164th, install signal/illumination system at 164th. Short term, intermittent, lanes and shoulder closures may be required to address roadside objects, etc. associated with the HAC.
