RE: Project Narrative
Ravi Short Plat is a proposed 3-lot single- family development located in the East Renton
Highlands at the intersection of 156th Avenue SE and SE 2nd Place. The project consists of 1
legal parcel creating a site of approximately 43,267 SF ( 0.99 acres) in size
Parcel # 142305-9033
Address: 6304 SE 2nd PL Renton WA 98059
The existing home will be retained and the accessory structures will be retained and converted
to an ADU. The parcel is within the city limits and zoned R-4. All parcels within the vicinity of the
site are also zoned 11-4. There is a similar residential development to the south of the project
site. (Cedar Ridge SP) There are no special features on site.
Topography descends to the southwest with about 18 feet of elevation change occur across the
site at an average slope of approximately 7%. Earth Solutions NW LLC in their Limited
Stormwater & Geologic Hazard Evaluation report dated November 2, 2021, describes the on -
site soils as:
Topsoil was encountered in the upper approximate 4 to 12 inches of existing grades. Fill was
encountered at TP-4 and TP-5, extending to a depth between about one to two -and -one-half
feet below the ground surface. Underlying topsoil and localized fill, native soils were
characterized primarily as silty sand with or without gravel (USCS: SM) for the upper four -and -
one -half feet. Thereafter, native soils transitioned into an unweathered condition and were
observed in a dense to very dense state, extending to a maximum exploration depth of about
nine feet. Based on the conditions encountered during our subsurface exploration, the site is
underlain by glacial till deposits.
Preliminary earthwork quantities include approximately 125 cubic yards of cut and 25 cubic
yards of fill to achieve grades shown on the current preliminary grading plan. These numbers do
Ravi SP
not factor in actual house foundations, which will lower the current estimated fill amounts
significantly.
The parcel currently exists as a single- family residential development. Parcel 142305-9033 has
several structures including residence and outbuilding. The existing detached garage will be
retained and converted into an ADU. Twenty trees have been mapped on the parcel by a
certified arborist and are identified in the plan set. Two trees have been identified as
dangerous. Eleven trees are proposed to be retained and no additional mitigation trees are
proposeA
.
SE 2nd Place is classified as a residential access. Existing improvements along that site frontage
include only a non- delineated paved shoulder ( no lane markings in SE 2nd Place). Proposed
improvements from right- of -way centerline will include 13 feet of pavement, vertical curb &
gutter, 8-foot planter strip and 5400t concrete sidewalk. Half right- of -way width along this
frontage is 30 feet. No right- of -way dedication is required. Construction of additional ROW
improvements is occurring on the south side of the road.
A small job shack can be anticipated on -site during construction. It is not currently Known if a
model home will be utilized as a sales tool for work on the other lots.
