B. ENVIRONMENTAL ELEMENTS
1. Earth
a. General description of the site (circle one): flat , rolling, hilly, steep slopes, mountainous.
The site is generally flat sloping down from the northwest to the southeast. The site is currently vacant with a dirt driveway/trail extending from the 160th avenue southeast, on the
west boundary, through the center of the site. The easterly portion of the site contains a wetland and associated buffer. The site contains numerous deciduous and conifer trees with
associated native ground cover vegetation.
b. What is the steepest slope on the site (approximate percent slope)?
According to the field topographic survey, the steepest slope on the site is approximately 10% at an isolated location just west of the center of the site..
What general types of soils are found on the site (for example, clay, sand, gravel, peat, and muck)? If you know the classification of agricultural soils, specify them and note any
prime farmland.
According to the USDA Natural Resources Conservation Services Web Soil Survey, the site is Alderwood gravelly sandy loam, 6 to 15 percent slopes
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe.
No surface indications or history of unstable soils in the immediate areawere discovered.
e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill.
Grading of the site will be necessary to provide a public street and associated storm drainage facilities. The exact quantity of grading is not known at this time, however, it is anticipated
that the grading activities would be designed to balance and not require import or export of soil. Grading of the individual home sites will involve the excavation of approximately
150 to 200 CY of cut and/or fill. These issues will be addressed during the building permit phase.
Plat construction is complete
f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.
Some erosion could occur on-site as a result of construction activities; however, temporary erosion and sedimentation control measures to be approved by the City of Renton will be employed
to reduce erosion impacts. All construction during the wet season will comply with the surface water design standards in place at the time of preliminary short plat approval.
Plat construction is complete the drainage system and detention are operational. BMP's are in place.
g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)?
Due to the preliminary nature of the plans, the exact percentage of impervious surface associated with this project is currently unknown. The subject proposal will not exceed the maximum
impervious surface area allowed by the City of Renton.
The approved TIR addressed these issues.
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:
During construction, the contractor will follow an approved temporary erosion and sedimentation control plan meeting City of Renton standards. Typical measures, which may be employed,
include the use of silt fences, straw bales, and temporary storm drainage features. Hydro seeding exposed soils and cleared areas after construction will also reduce the potential
for erosion.
The SWPPP was adhered to during plat construction and BMP's will be used during home construction.
2. Air
a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, and industrial wood smoke) during construction and when the project is completed?
If any, generally describe and give approximate quantities if known.
Construction:
Emissions and dust particulates generated primarily by construction equipment will be produced during the construction phase of this project. The amount of emissions to the air will
be minimal and will occur during the actual construction of the development.
Long Term Air Quality:
Long-term air impacts would be those typically associated with residential land uses. Sources of long-term emissions and odor could include vehicle emissions from increased vehicle
use generated by the new residential units and emissions from wood burning fireplaces (if permitted). The additional vehicular emissions in these areas are not anticipated to concentrate
and therefore are not anticipated to create a health hazard to the residents or surrounding areas.
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:
If particulates become suspended during construction, frequent watering of the site during the construction phase of the project would be used to help control dust and other particulates
generated on the site.
