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:
For nonproject proposals (such as ordinances, regulations, plans and programs), complete the
applicable parts of sections A and B even though questions may be answered “does not apply”.
In addition 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 area” respectively. The lead agency may exclude (for non‐projects) questions in Part
B ‐ Environmental Elements –that do not contribute meaningfully to the analysis of the
proposal. For help go to: http://www.ecy.wa.gov/programs/sea/sepa/e‐review.html

The proposed project is to subdivide two (2) parcels with a combined size of 4.07
acres located in the easterly portion of the Highlands of the City of Renton. The
proposal is to create 15 new single family lots. There are three existing houses on

B. ENVIRONMENTAL ELEMENTS
1. EARTH
a. General description of the site
(check or circle one):
Flat, gently sloping from NE to SW at 3%
rolling,
hilly,
steep slopes,
mountainous,
other _____________
b. What is the steepest slope on the site (approximate percent slope)?
Small area at 13%
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.
Silty sands and gravels (weathered till)
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so,
describe.
No
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.
Approximately 1,900 cu. yards of material will be excavated from the proposed
stormwater facility. 2800 cubic yards of material will be needed to backfill the
stormwater vault and the surrounding lots to make final grades. The road
excavation will be generating 1,200 cu. yards of stripping to obtain subgrade.
Based upon the timing of construction, import gravel backfill material may be
necessary to obtain proper compaction within utility trenches and final grades
of lots.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.
Minimal erosion may occur on site during construction of the necessary
utilities and roadways. Onsite erosion control measures will be utilized to
control erosion during construction.
g. About what percent of the site will be covered with impervious surfaces after project
construction (for example, asphalt or buildings)?
45%
5
C:\Offe Engineers\Aaa Projects\Kendall Homes\Renton 14\SEPA\Renton 14 Plat.doc Rev: 08/2015
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:
Best management practices will be utilized during construction to reduce
erosion during construction. Installation of silt fences, providing a temporary
settling pond, minimizing exposed soils to weather, and the use of existing
hard surface driveways for construction entrances; these measures will
minimize erosion during construction.
2. AIR
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.
Emissions from construction equipment will be present during construction.
Possible dust may occur during the drier weather months.
b. Are there any off‐site sources of emissions or odor that may affect your proposal? If so,
generally describe.
No
c. Proposed measures to reduce or control emissions or other impacts to air, if any:
Construction equipment on site should be operated meeting current state and
federal emission standards. The use of hard surface existing driveways as
construction enters will provide for reduced dust. The use of dust control
measures (water) will be used during construction to reduce emission into the
air.
3. WATER

from surface water or wetlands and indicate the area of the site that would be
affected. Indicate the source of fill material.

so, give a general description of the well, proposed uses and approximate quantities
withdrawn from the well. Will water be discharged to groundwater? Give general
description, purpose, and approximate quantities if known.
No
2) Describe waste material that will be discharged into the ground from septic tanks or
other sources, if any (for example: Domestic sewage; industrial, containing the
following chemicals. ; agricultural; etc.). Describe the general size of the system, the
number of such systems, the number of houses to be served (if applicable), or the
number of animals or humans the system(s) are expected to serve.
There is no proposal on this project to discharge any waste material into
the ground. Domestic sewage service will be provided by the City of Renton
utilizing existing sewage conveyance systems.
c. Water runoff (including stormwater):
1) Describe the source of runoff (including storm water) and method of collection
and disposal, if any (include quantities, if known). Where will this water flow?
Will this water flow into other waters? If so, describe.
Storm water runoff will be generated from developed impervious
surfaces and pervious surfaces (such as landscape areas, lawns,
etc.). The runoff will be collected within catch basins and conveyed
to a proposed storm water vault located in the southwest corner of
the project. The storm water vault will treat and control the
discharge of the runoff at the natural discharge location off the
project, southwest corner.

the site? If so, describe.
No
d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage
pattern impacts, if any:
The proposed storm water treatment vault will be designed and
constructed to reduce impacts to the downstream drainage course.
The vault will discharge the developed runoff at a pre-developed
“forested” conditions runoff. This will reduce the developed
discharge below levels (flow rates) from the current property
conditions. A water quality treatment feature will be provided within
the vault (called “dead storage”) to treat and provide space for
settling of pollutants from the developed runoff.
