ENVIRONMENTAL CHECKLIST
City of Renton Planning Division
1055 South Grady Way-Renton, WA 98057
Phone: 425-430-7200 Fax: 425-430-7231
PURPOSE OF CHECKLIST:
The State Environmental Policy Act (SEPA), Chapter 43.21C RCW, requires all governmental
agencies to consider the environmental impacts of a proposal before making decisions. An
Environmental Impact Statement (EIS) must be prepared for all proposals with probable
significant adverse impacts on the quality of the environment. The purpose of this checklist is
to provide information to help you and the agency identify impacts from your proposal (and to
reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide
whether an EIS is required.
INSTRUCTIONS FOR APPLICANTS:
This environmental checklist asks you to describe some basic information about your proposal.
Governmental agencies use this checklist to determine whether the environmental impacts of
your proposal are significant, requiring preparation of an EIS. Answer the questions briefly,
with the most precise information known, or give the best description you can.
You must answer each question accurately and carefully, to the best of your knowledge. In
most cases, you should be able to answer the questions from your own observations or project
plans without the need to hire experts. If you really do not know the answer, or if a question
does not apply to your proposal, write "do not know" or "does not apply". Complete answers
to the questions now may avoid unnecessary delays later.
Some questions ask about governmental regulations, such as zoning, shoreline, and landmark
designations. Answer these questions if you can. If you have problems, the governmental
agencies can assist you.
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.
USE OF CHECKLIST FOR NONPROJECT PROPOSALS:
Complete this checklist for nonproject proposals, even though questions may be answered
"does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT
ACTIONS (part 0).
For nonproject actions (actions involving decisions on policies, plans and programs), the
references in the checklist to the words "project," "applicant," and "property or site" should be
read as "proposal," "proposer," and "affected geographic area," respectively.

B. ENVIRONMENTAL ELEMENTS
1. EARTH
a. General description of the site (circle one);
mountainous, other
flat , Lolling, hilly , steep slopes,
b. What is the steepest slope on the site (approximate percent slope?)
The project site has an average slope between 10 and 15 percent; however, there
is an isolated area with a 25 percent slope.
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 prime farmland.
Please reference the soils report prepared by Associated Earth Sciences, Inc.
d. Are there surface indications or history of unstable soils in the immediate
vicinity? If so, describe.
No.
e. Describe the purpose, type, and approximate quantities of any filling or grading
proposed. Indicate source of fill.
A preliminary grading plan has been prepared for this project and a copy has
been attached. Based on this plan, we anticipate that the on-site structural
grading to balance is approximately 95,000 cubic yards of cut and fill. The
on-site strippings (topsoil) is estimated at 22,000 cubic yards and will either be
spread on the finished lots and/or exported off site.
At this time no import or export of material is expected. Some additional grading
will occur on a lot by lot basis during the home construction phase.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally
describe.
No. Minor (and temporary) soil erosion could occur as a result of the site clearing
excavation and grading. However, as required by City Code, a Temporary Erosion
and Sedimentation Control Plan (TESCP) will be prepared and implemented.
Additionally, erosion control Best Management Practices (BMPs) will be provided
(i.e., straw mulch, silt fences, rock check dams, etc.).
g. About what percent of the site will be covered with impervious surfaces after
project construction (for example, asphalt or buildings)?
The total on-site impervious surface (roadways) will be approximately 4.65 acres
(or 21%) of the site area (21.7 acres). Based on a maximum impervious area per
lot of 75 percent, we have estimated a total impervious area (for 98 lots with an
average lot size of 5,200 square feet) of approximately 8.75 acres or 382,255
square feet.
10055,004.doc - 4 - 06/09
h. Proposed measures to reduce or control erosion, or other impacts to the earth,
if any:
All applicable BMPs and other normal and necessary TESC measures will be
incorporated during the plat and home construction.
2. AIR
a. What types of emissions to the air would result from the proposal (i.e., dust,
automobile, odors, industrial wood smoke) during construction and when the
project is completed? If any, generally describe and give approximate quantities
if known.
During plat and home construction, emissions from construction equipment and
vehicles will occur on a temporary basis. When houses are completed there will
be emissions generated from automobile/service truck traffic. At this time there
are no known quantities.
b. Are there any off-site sources of emission or odor that may affect your
proposal? If so, generally describe.
The site is surrounded by existing single-family developments that generate
typical residential emissions; however, there are no known emissions that will
affect this project.
c. Proposed measures to reduce or control emissions or other impacts to air, if
any:

6) Does the proposal involve any discharges of waste materials to surface waters?
If so, describe the type of waste and anticipated volume of discharge.
No.
b. Ground Water:
1) Will ground water be withdrawn, or will water be discharged to ground water?
Give general description, purpose, and approximate quantities if known.
There will be no groundwater withdrawn as a result of this project (public water
will be provided); however, stormwater will be collected by a gravity drainage
system and discharged to an on-site storm pond. The stormwater collected will
be discharged at an approved rate into the existing storm system within S.E. 18th
Street. Also, some stormwater collected from the house roof drains will be
discharged into the on-site wetlands to provide a re-charge during storm events.
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.

c. Water Runoff (including storm water):
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 will be collected by a series of catch basins and conveyed by
stormwater pipe to the on-site storm pond (detention) designed in accordance
with the City of Renton Storm water Design Manual (Addendum to the King
County stormwater guidelines). The system will also convey drainage from roof
and footings drains to the storm pond.
2) Could waste material enter ground or surface waters? If so, generally describe.
16055.004.doc - 6 - 06/09
Unlikely. As discussed above, all storm water will be collected and conveyed to an
approved detention pond. Furthermore, the storm water will pass through a
storm filter vault (water quality) prior to discharge off site.
d. Proposed measures to reduce or control surface, ground, and runoff water
impacts, if any:
As previously discussed, all drainage will be collected and treated (storm filter
vault) prior to discharge (for more detailed discussion see the attached
storm water TIA prepared by Barghausen Consulting Engineers, Inc.).

a. Would the project result in an increased need for public services (for example:
fire protection, police protection, health care, schools, other)? If so, generally
describe.
The future construction of homes on each of the 98 lots will result in a
proportional need for public services normally associated with single-family
development such as police, fire, health care, schools, postal service, garbage
service, etc.
b. Proposed measures to reduce or control direct impacts on public services, if any.
Building the on-site roads to public standards will provide an acceptable means
of access for any needed public services to existing lots. Property tax revenue will
assist with offsetting the proportional impact on public services. Mitigation fees
will be collected at the time of building permit for individual lots to offset traffic,
fire, and school impacts as well.
16. UTILITIES
Circle utilities currently available at the site: electricity, a. natural gas water
refuse service , telephone, sanitary sewer, septic system, other.
