Subject: Cascade Center - Multi-Family TIA Scoping

Importance: Normal

Good afternoon Gerald,

We are working with AKS and I&E to prepare a traffic impact study for a proposed multi-family development south of the Cascade Center commercial property on the south side of OR 211 at Leroy Avenue. Following up on the recent pre-app meeting, we wanted to confirm the traffic study assumptions with you all before we move forward with the TIA. Could you please confirm and/or comment on the following?:

• * The TIA will include the same study intersections as the recent Cascade Center studies:
  • * OR 211/OR 213
  • * OR 211/Hezzie Ln
  • * OR 211/Leroy Ave
  • * OR 211/Dixon Ave
  • * OR 211/Molalla Ave

We propose to use historical count data collected at these intersections in fall 2018 and apply a 2.5-percent annual growth rate to arrive at 2021 volumes, as well as a seasonal adjustment factor. Could you please confirm the City will accept this approach?

• * We will include the following as in-process developments:

o Cascade Center commercial development (Traffic Impact Analysis dated March 2019 and Addendum dated July 2020)

o Colima Apartments (Traffic Impact Analysis dated November 2019 and Addendum dated January 2020)

Could you please confirm if there are other approved developments that should be included as in-process?

• * We will assess signal warrants at the OR 211/Leroy Ave intersection after site build-out using the City’s trip threshold.
• * Would you all like us to reach out to ODOT for additional scoping comments, or will you be handling coordination with ODOT?

At this time, the team is still finalizing the site plan layout and number of multi-family units, as well as the anticipated build-out year. Please let us know if you will require more detail on these elements beyond what was shared at the pre-app meeting in order to respond to the items above, and we can circle back with the team.

Thank you,

Zach
