SHORELINE TRACKING WORKSHEET
Planning Division
1055 South Grady Way, Renton, WA 98057
Phone: 425-430-7200 | www.rentonwa.gov
The City of Renton is required by the Washington State Department of Ecology to track and evaluate the effectiveness of
the Shoreline Master Program at achieving no net loss of shoreline ecological functions with respect to shoreline
projects. The City will use shoreline development tracking information to prepare a Shoreline Master Program report
every eight years to comply with the Shoreline Management Act requirements.
SHORELINE STABILIZATION
1. Is there currently a bulkhead on your site? Yes No; If yes, fill out table below.
If no, see “Site Conditions”, Section 2 below.
What Type of Materials is Your Bulkhead Made of? Linear Feet of Hard
Materials:
Linear Feet of Soft Materials:
Examples of Types of Bulkheads: Hard (e.g. rocks, wood); Soft (e.g. sand, plants); Combination-soft
materials at the water with hard materials further inland, or a combination of hard and soft materials at
the water.
SITE CONDITIONS
2. List the size (in square feet) and type of all structures (1st floor only) on your property (e.g. 2,000 sq. ft.
house, 125 sq. ft. greenhouse).
There are no structures located on the site of the temporary construction entrance.
List distance (in feet) from the water to the closest point of each structure. List each building separately
(e.g. shed, dock, carport).
N/A
3. List the size (in square feet) and type of all impervious surfaces (e.g. driveway, parking area, walkway,
patio).
The 4,375 square foot (175-foot x 25-foot) temporary construction entrance would extend from the
existing asphalt plant road, located west of Springbrook Creek, towards the spoils placement location
within an open lawn area of the STP site further to the west. The construction entrance would consist of 4-

inch to 8-inch quarry spalls, 12 inches thick and underlain by geotextile fabric. Hog fuel may be substituted
for or combined with quarry spalls. The temporary construction entrance will be removed following
construction and the site restored.
4. List distance (in feet) from the water to the closest point of each impervious surface (hard surface).
The temporary construction driveway would be located within 128 feet from the ordinary high water
mark.
5. Describe the existing vegetation within 100 ft. of the waterline. Estimate the amount (in square feet) of
native vegetation. Grass and ornamental plantings (e.g. plants requiring care or grown for decorative
purposes) should not be counted.
Existing vegetation within the vegetated riparian corridor of the creek is typical native riparian forest species
and includes a mixture of red alder, willow species, Himalayan blackberry and sedges (Carex spp.) along with
some ornamental trees. Conifers are almost exclusively absent and in those areas where shade was absent
reed canary grass is abundant. The entirety of the 100-foot-wide riparian area is vegetated except for a 15-
foot-wide paved trail.
6. Will the project require any added fill? If so, how many cubic yards will be added:
Approximately 290 cubic yards (CY) of soil would be excavated and approximately 120 CY of quarry spalls
would be placed to construct the temporary construction entrance. Quarry spalls will be removed from the
site following construction. Excavated soil will be reused onsite to restore the existing grades following
construction.
IN WATER AND OVER WATER STRUCTURES
7. Are there any in or over water structures on your site (e.g. docks, floats, bridges, mooring piles, boatlifts)?
Yes No; If yes, fill out the table below.
Describe the in- and over-water structures on your site
The city property includes docks and other park-related structures.

mooring pile, boat lift, etc.)

applicable)
