TENW Transportation Engineering North West MEMORANDUM DATE: April 10, 2018 TO: David Ratliff, Vice President DevCo, Inc. FROM: Michael Read, PE, Principal, TENW SUBJECT: Riverview Apartments - REVII 17-024 & SEPA17-019 Response to Traffic Comments from City of Everett on March 7, 2018 TENW Project No. 3537 This memorandum provides a response to Item 23 within the City of Everett Public Works Department comments on the Riverview Apartments Traffic Impact Analysis provided to DevCo., Inc. on March 7, 2018. The comment related to a request for a custom trip generation rates be prepared for the proposed supportive/affordable housing project. Response 1: Since completion of the original Traffic Impact Analysis, the Institute of Transportation Engineers (ITE) has published the 1 Oth Edition of the Trip Generalion Manual, December 2017. Within this document, are published rates for "typical" mid -rise apartment complexes in general urban/suburban locations in Land Use Code 221, with between 50 and 60 sites surveyed in this category with correlative fitted curve equations. As such, the study has been updated to reflect these new land use categories and significant level of surveys without regard for the supportive or affordable nature of the units as a worse -case scenario. With these revisions, a net increase of approximately 68 new p.m. peak hour trips (2 more than the November 2017 study) are estimated, and as such, no changes in level of service or other findings or conclusions have resulted as part of this study update.
