The proposed project involves approximately 1,700 linear feet of improvements to portions of 53rd Avenue South, 54th Avenue South, and South 166th Street. Improvements include pavement widening from 24 feet to 34 feet, pavement overlay, adding curb and gutter to both sides, adding a sidewalk to the west side, improving the storm drainage system, undergrounding power in a portion of the project, driveway repairs and minor adjustments to manhole covers and valve boxes. The construction period is 60 days. 7. The proposed project is located within the 53rd Avenue South right - of -way and adjacent private properties for which "licenses to construct" have been obtained. The project extends between South 170th Street and approximately South 166th Street, generally within the City of Tukwila. A small portion of the project is located within unincorporated King County. 53rd Avenue South runs generally perpendicular to the slope of the hill, sloping up from the west road shoulder and down from the east road shoulder. II. ENVIRONMENTAL IMPACTS 1. b., c. Construction of the road improvements will require earthwork. The 53rd Avenue South right -of -way runs generally perpendicular to the slope of the hill. The pro- posed improvements will require cuts, and some fill. Minor rock walls (4' - 5' in height) will be used to stabilize side slopes as required. One steel bin wall will be installed along a portion of 54th Avenue South. A soils report was prepared for the project in June, 1983. This report included recommendations on cut and fill slopes and retaining structures, and general considerations of stability of steep slopes. The engineering design is con- sistent with this report. e. The Contractor will be required to control erosion during construction. Regarding long -term erosion, hydroseeding and re-sodding of all exposed surfaces as well as installation of an improved storm drainage system will minimize potential ero- sion problems. 6D.T • • -2- 2. a.,b. Construction activities will cause a temporary increase in suspended particulates and odors. The contractor.will be required to control dust during the construction. The deterioration to ambient air quality is not expected to be significant, especially due to the short duration (60 days) of the construction period. 3. b. A hydraulic analysis of this drainage basin was prepared as part of this project. The increased pavement will result in some increase in storm water run -off, but proposed improvements to the storm drainage system will improve drainage within the roadway system. Some existing problems will be eliminated and other problems reduced. Proposed improvements include laying pipe at proper grades, increasing pipe sizes where necessary, and crowning the road to better control run -off. All drainage will now be directed to the south end of the street to an existing storm drainage system. The ultimate point of discharge will not be changed. 13. a. Construction activities will result in an increase in truck traffic for the 60 day construction period. c. The contractor will provide one driveable roadway lane and tem- porary access to all properties throughout the course of the project. During construction, all roads will be maintained in a suitable condition so as to not adversely affect vehicular traffic. 53rd Avenue South is used primarily as a residential local access street. The proposed improvement should not appreciably increase traffic volumes. Traffic hazards will be reduced. 16. The remaining above - ground telephone and cable t.v. will be undergrounded. Water District #75 is coordinating a main replace- ment project with the street improvement project. A new storm drainage system is being constructed. 6D.T1
