Stream Corridor Assessment Guide Overview:

The individual components of stream corridors have a significant inter-relationship that directly impacts on the function and stability of the other components as well as that of the whole corridor.  This directly impacts on the land uses and infrastructure located within that corridor as well as the resilience of the stream system.  The assessment of these corridor components exists in many reference materials at varying level of technical aptitude.   The goal of this project was to research existing reference/assessment materials to develop an entry level assessment that format and support materials that would be suitable to collect a “level one” determination of stream corridor condition and the need to refer to further expertise.  Once developed, the assessment guide and protocol would under-go peer review and training would be provided to audiences with minimal stream assessment experience and training to determine suitability of the tool.

Final Stream Corridor Assessment Guide - 4-21-17 - This document outlines the criteria for completion of a visual assessment of the stream corridor functional health and flooding resiliency as described below as part of a landowner/farmer site visit, potentially in conjunction with an AEM Inventory.

1 - WATERSHED BACKGROUND REPORT

A comprehensive overview of the watershed and stream channel. The report is an exhaustive search of existing information and data on the watershed and influences on water quality and quantity. The report provides a “first step” in determining needed research and data collection in order to make informed decisions for management and corrective actions. Topics may include such items as:

EXECUTIVE SUMMARY

 

2 – STREAM CHANNEL &/OR BANK STABILIZATION DESIGN PACKAGE

A design for specific stream sites based on sound engineering and hydrologic principles with a consideration for re-establishing stable channel conditions and natural stream functions. Designs are developed through requests by USC members for municipalities and landowners. A typical design package would include:

  A: Project Overview

  • Narrative
  • Design Procedures
  • Project Information Summary
  • Location Information and Maps
  • Operation and Maintenance Plan
  • Permit
  • PNDI
  • Landowner Consent Form

B: Design Information

  • Survey Information
  • Design Calculations
  • Design Specifications - NRCS Conservation Practice Standard (580)
  • Quantity Computations
  • Project Cost Estimate
  • Quality Assurance Plan

C: Construction Information

  • Pre-construction Checklist
  • PA One-Call
  • Installation Sequence and Contractors Notification List (i.e. Before starting construction, install rock construction entrance.)
  • E&S Plan
  • Construction Specifications (additional conditions)
  • Drawings - Cover Sheet, Plan View, Proposed Cross Section, Typical Rip-Rap Installation

3 – A STREAM REACH / WATERSHED TRIAGE REPORT

A comprehensive analysis of identified stream channel problems that includes a description of causes and effects, an analysis of potential strategies to address the identified problems and a cost estimate for each strategy. The Triage Report provides a solid basis for prioritizing sites and distributing resources. Reports also can be utilized to assess needed resources and providing a structured proposal for potential funding sources in addressing watershed needs.

Report findings would include:

Summary --
Purpose --
Methodology --
Data Recording
General Note --
Remediation Costs --
Observations on Common Causes of Instability, such as:

  1. Alteration and Removal of Vegetative Cover
  2. Channel Encroachment / Floodplain Restriction
  3. Debris Jams
  4. Anthropogenic Channel Alteration
  5. Transitional Areas
  6. Geology and Soils

Impairment Findings and Potential Recommendations --

  1. Lack of Riparian Vegetation
  2. Culvert Outlets
  3. Entrenchment / Channel Straightening / Lack of Floodplain Access
  4. Mid-Channel Deposition
  5. Bank Saturation
  6. Road / Structure Encroachment
  7. Debris Jams
  8. Rip-Rap

Streambank / Stream Channel Rehabilitation Strategies

The following is a listing is an example of remediation strategies considered at each site during the assessment and triage phases of the project.

  • Natural Stream Channel Design
  • Toe Protection
  • Deflectors
  • Gabions
  • Vanes / J-hooks
  • Bank grading
  • Bankfull Bench
  • Cribbing
  • Channel Block / Curb
  • Stone / Block Wall
  • Gabion with Plantings
  • Plantings
  • Bank Drains (French drain system)
  • Energy dissipation
  • No Action
  • Combination of various practices
