The Maple Highlands Preliminary Plat project proposes creating 12 new single-family lots along with
associated access, utility, and stormwater infrastructure. The project site is approximately 4.16 acres
consisting of two parcels (1463400020 &1463400021) located between 152nd Avenue SE and 154th
Avenue SE. The project site is zoned R-4 residential and is used as single-family residential with two
existing single-family homes. The project site will continue to be used a single-family residential
following completion of the plat. No critical areas are present at the project location. The soil
conditions identified include loose to medium dense sand with some silt and silty sand with some
gravel over dense to very dense silty sand with varying amounts of gravel glacial till.
The proposed development will include the construction of 12 new single-family homes and
supporting infrastructure, including a wetpool-detention pond and associated utility work The plat will
be designed in accordance with all applicable development standards. Access will be provided to
new homes via a new cross street (SE 139th Place) and new access roadway (153rd Avenue SE). The
roadways will be public and dedicated to the City of Renton. A two-car garage will be provided with
each home. The total estimated construction cost of the proposed project is $2.1M, and the
estimated fair market value of the proposed project is $3.6M.
Grading and tree removal will be required to develop the appropriate infrastructure. Cut is estimated
to include 2,000 cubic yards of dirt. Fill will be approximately 12,000 cubic yards of borrow fill,
resulting in a net of 10,000 cubic yards of fill for the site.
The plat includes creation of 12 lots that range in size from 9,031 square feet to 11,256 square
feet, with the majority of lots (9 of the 12) being less than 10,000 square feet. The proposed storm
tract is 21,846 square feet in size. The final density of the proposed development is approximately
3.8 du/ac.
