From: Brad Lincoln, PE
Project: Stinde Development
GTC #16-073
Subject: Traffic Analysis
Date: July 19, 2016
This memorandum summarizes the trip generation calculations for the Stinde Development. The
development is located on the east side of Monroe Avenue NE, south of NE 10th Street. The
development is proposed to replace two existing single-family residential units with 14 single-family
residential units, a net increase of 12 single-family residential units. A site vicinity map in included

Trip Generation Calculations
The trip generation calculations for the Stinde Development are based on data contained in the
Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 9th Edition – Volume 2: Data
(2012). The average trip generation rates for ITE Land Use Code 210, Single-Family Detached
Housing, have been used for the trip generation calculations for the proposed 14-unit development.
Table 1 summarizes the trip generation calculations.

The Stinde Development is expected to generate 114 new average daily trips with 9 new AM peak-
hour trips and 12 new PM peak-hour trips. The ITE data for Land Use Code 210 is included in the
attachments.
Trip Distribution and Impacts
It is anticipated that trips generated by the Stinde Development will split 60% traveling to and from
the north and 40% traveling to and from the south along Monroe Avenue. The development will
impact off-site City of Renton intersections with less than 10 peak-hour. Additional analysis of
impacts to surrounding intersections should therefore not be required based on City of Renton
threshold requirements.
