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
1. 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 or buildings in the shoreline within the project area.
2. List distance (in feet) from the water to the closest point of each structure. List each building separately
(e.g. shed, dock, carport).
Not applicable; there are no structures or buildings in the shoreline within the project area.
3. List the size (in square feet) and type of all impervious surfaces (e.g. driveway, parking area, walkway,
patio).
Existing impervious surfaces in the shoreline within the project area are associated with the Maple Valley
Highway, representing approximately 5,000 square feet of pavement.

4. List distance (in feet) from the water to the closest point of each impervious surface (hard surface).
The south side of the Maple Valley Highway is located immediately adjacent to the Cedar River.
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.
The Maple Valley Highway is adjacent to the northern bank of the Cedar River within the project area. A
large concrete retaining wall at the river bank limits vegetation in this area. On the southern side of the
Cedar River, vegetation within 100 feet of the waterline is characterized by a predominantly deciduous
canopy of red alder, big leaf maple and black cottonwood. Upland understory is dominated by non-native,
invasive Himalayan blackberry. A portion of Wetland NRO2, a depressional wetland dominated by
palustrine scrub-shrub and forested vegetation, is present within 100 feet of the OHWM. Common plants
observed within Wetland NRO2 include red alder, black cottonwood, salmonberry, redtwig dogwood,
blackberry, skunk cabbage and lady fern.
Invasive blackberry is estimated at 60-90 percent of the project area in this vicinity. Due to the high level of
invasive coverage, native vegetation within 100 feet of the waterline is estimated at 1,000 to 4,000 square
feet within the project area.
6. Will the project require any added fill? If so, how many cubic yards will be added:
No added fill is proposed within the shoreline associated with this project.
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.
