ENV ENVIRONMENTAL CHECKLIST
Planning Division
1055 South Grady Way-Renton, WA 98057
Phone: 425-430-7200 | www.rentonwa.gov
PURPOSE OF CHECKLIST: Governmental agencies use this checklist to help determine whether
the environmental impacts of your proposal are significant. This information is also helpful to
determine if available avoidance, minimization or compensatory mitigation measures will address
the probable significant impacts or if an environmental impact statement will be prepared to
further analyze the proposal.
INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic
information about your proposal. Please answer each question accurately and carefully, to the
best of your knowledge. You may need to consult with an agency specialist or private consultant
for some questions. You may use “not applicable” or "does not apply" only when you can explain
why it does not apply and not when the answer is unknown. You may also attach or incorporate
by reference additional studies reports. Complete and accurate answers to these questions often
avoid delays with the SEPA process as well as later in the decision-making process.
The checklist questions apply to all parts of your proposal, even if you plan to do them over a
period of time or on different parcels of land. Attach any additional information that will help
describe your proposal or its environmental effects. The agency to which you submit this
checklist may ask you to explain your answers or provide additional information reasonably
related to determining if there may be significant adverse impact.
INSTRUCTIONS FOR LEAD AGENCIES: Additional information may be necessary to evaluate the
existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts.
The checklist is considered the first but not necessarily the only source of information needed to
make an adequate threshold determination. Once a threshold determination is made, the lead
agency is responsible for the completeness and accuracy of the checklist and other supporting
documents.
USE OF CHECKLIST FOR NONPROJECT PROPOSALS: [help] For nonproject proposals (such as
ordinances, regulations, plans and programs), complete the applicable parts of sections A and B
plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D).
Please completely answer all questions that apply and note that the words "project," "applicant,"
and "property or site" should be read as "proposal," "proponent," and "affected geographic

This project proposes to divide a single parcel totaling 4.54 acres into 14 lots along with
associated roadway and utility infrastructure. Access to the new lots is to be provided
from a new internal road heading west from 156th Ave SE to 154th Avenue SE.
12. Location of the proposal. Give sufficient information for a person to understand the precise

B. ENVIRONMENTAL ELEMENTS [help]
1. EARTH
a. General description of the site [help]
(check or circle one): Flat, rolling, hilly, steep slopes, mountainous, other: constant slope
b. What is the steepest slope on the site (approximate percent slope)? [help]
15%
c. What general types of soils are found on the site (for example, clay, sand, gravel, peat,
muck)? If you know the classification of agricultural soils, specify them and note any
agricultural land of long-term commercial significance and whether the proposal results in
removing any of these soils. [help]
According to the Natural Resources Conservation Service, the soil types are
Alderwood gravelly sandy loam (AgC). A detailed soils analysis is provided in the
Geotechnical Engineering Study, prepared by Terra Associates, Inc. dated
February 2, 2017.
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so,
describe. [help]
There are no surface indications of unstable soils in the immediate vicinity of the site. A
Geotechnical Engineering Study, prepared by Terra Associates, Inc. dated February 2,
2017 is available.
e. Describe the purpose, type, total area, and approximate quantities and total affected area
of any filling, excavation, and grading proposed. Indicate source of fill. [help]
Grading and filling activities are proposed to accommodate the improvements for the
residential buildings, access roads, and associated utilities. On-site soils will be used as
fill to the extent feasible. Should additional fill material be required, said material will
be acquired locally from approved sources. Potential imports could include crushed base
courses, gravel backfill, trench backfill, and asphalt pavement (as required).
Preliminary estimated quantities for structural fill on-site is approximately 10,000 cubic
yards of cut and 12,000 cubic yards of fill material. It is anticipated that during
development of the final engineering plans a balanced site can be achieved. Any surplus
soil materials that can not be utilized on-site for landscape area and backfill will be
hauled to an approved off-site location.

measures, in accordance with current standards during the construction phase to
mitigate any erosion and sedimentation potential.
2. AIR [help]
a. What types of emissions to the air would result from the proposal during construction,
operation, and maintenance when the project is completed? If any, generally describe and
give approximate quantities if known. [help]
During the construction phase, there would be periods of increased dust and vehicle
emissions. After the construction phase is complete there would be an increase in
vehicle emissions due to the increased number of vehicle trips per day to and from the
site.

a series of catch basins that will be connected by underground pipes. The
pipes will convey this water to a detention/water quality facility to treat
runoff in accordance with City stormwater standards. This facility will
discharge to an existing ditch within the 154th Ave SE Right-of-Way. The
storm water system eventually flows to Cedar River approximately 4,500 feet

A total of 10 – AM peak trips and 14 – PM peak trips are anticipated once the project is
complete. City guidelines require a traffic study if the project generates more than 20
peak hour trips. As this project does not generate more than 20 peak hour trips, a full
scale traffic study was not performed. Edward Koltonowski at Gibson Traffic Consultants
provided this information.

a. Would the project result in an increased need for public services (for example: fire
protection, police protection, public transit, health care, schools, other)? If so, generally
describe. [help]
