This project is located in Clallam County, Wa on SR-112 mile post 47.1 at the crossing of Nelson Creek. The site is location in the Olympic Region west of Port Angeles


Project description
Project Description

  • Removal of existing box culvert

  • Construction of a 16’ wide by 10’ high culvert

    • Precast 3-sided culvert with wing walls.

    • Strip footing foundations

  • 130’ long structural earth wall on South side

    • Reconstruct existing embankments to a slope of 2H:1V

  • New pavement for roadway

    • Approximately 175’


Project justification
Project Justification

  • The restoration of declining salmon and trout populations

    • Inability to utilize spawning grounds

    • Opening passage to natural habitat

    • Coho Salmon and Steelhead

    • sea run and resident Cutthroat Trout


Project scope
Project Scope

  • develop a traffic re-routing plan

  • Pavement design of new roadway

    • Existing impervious surface 17780 approx. 740 ft.

    • New impervious surface 4200 approx. 175 ft.

  • Embankment improvements

  • Earth wall and erosion control design

  • Removal of existing culvert

  • Design of new culvert, wing walls, foundation and strip footings.

Soil borrow
Soil Borrow

  • Decision Matrix:

  • Gravel borrow chosen.

    • Less sensitivity to moisture.


Culvert design
Culvert Design

  • Culvert sidewalls are loaded axially and laterally. Have to consider ΦPn and ΦMn. Have to develop a interaction diagram and also consider the limit of cracking at service state.


Culvert design1
Culvert Design

Channel restoration

  • Culvert bed material will consist of well graded stream bed sediment (Standard spec 9-03.11.1), stream bed cobbles (Standard spec 9-03.11.2), and stream bed boulders (Standard sec 9-03-.11.3)


Culvert design2
Culvert Design

  • For Precast Culvert installation we will need 14 units total to achieve 106 LF (14 joints adding 3.25” in length)


Structural earth wall
Structural Earth Wall

  • South side of project.

  • Approximately 130 feet long.

  • No more than 20 feet exposed height.

  • A 4 foot bench before slope.

  • Requirements:

    • A 2H:1V slope.

    • Vegetation to be planted for erosion control


Erosion control
Erosion Control

  • Vegetation:

    • Will be from native plants chosen based on effectiveness.

  • Other:

    • Wattles, compost socks, and and erosion control blankets will be considered.
