## Channel Rehabilitation ProjectsTAMWG  -  June ‘04

- Trinity River at Hocker Flat 1/16/2003

## Effects of Trinity and Lewiston Dams on channel morphology and fish habitat 

## Rehabilitation Site Objectives

- Remove encroached riparian vegetation
- Take the “handcuffs” off the river
- Initiate natural river processes
- Re-scale floodplain for current and anticipated flow regime
- Allow the river to create needed habitat variety
- Revegetate in accordance with required permits

## Hocker Flat

- _Hocker Flat_

## Design Criteria

- Dry winter low water surface elevation
- Feathered edges
- Seasonal groundwater for revegetation
- 1.5 year recurrance frequency water surface elevation
- Floodplain excavation
- Theoretical river meander dimension
- Floodplain management considerations

## Rehabilitation Site Issues

- FEMA
- Realty
- Revegetation
- Environmental Compliance

## Environmental Compliance

- National Environmental Policy Act (NEPA)
- Requires federal agencies to analyze and disclose the environmental effects of their proposed actions
- California Environmental Quality Act
- State equivalent to NEPA..... but ALSO –
- Requires **REDUCING**** **environmental effects
**Both promote efforts to minimize environmental effects via public participation and documentation**

**Notes:**
CEQA- State agencies have jurisdiction by law over natural resources affected by a project that are held in trust for people of the state.  
DIFFERENCE BETWEEN NEPA & CEQA:
CEQA requires Mitigation Monitoring and Reporting Plans and to minimize effects with the “right” alternative.  
CEQA basis of comparison is the existing condition vs. NEPA = no Action.
_____________________________________________________
Env. Compliance has not been tried yet for the bridges project.  That’s what I am here for.  That’s why I came and what I want to do....not bridges.
These are uncharted waters.  That said, a couple of keys remain true.  
1) Bring everyone in and get the best ideas included ....ASAP.
2) Move forward in a coordinated fashion.  Ready to play your hidden card (new Plan)  e.g., Bridges 1 bid  Fall 2003, Spring 2004 Flows, summer/fall 2004.

The schedules we present are assed on moving forward  w/agreement – consensus (e.g., on flow).  Let’s do what we can agree on.  We determine what’s right and move forward (we are the permitters).  Once we decide what we need, we only have to make it happen.  .  

## NEPA: Federal 
Lead = Agency with primary responsibility for preparing an Env. Document
			U.S. Bureau of Reclamation 		(Trinity River Restoration Program)
Cooperating Agency = jurisdiction by law or special expertise 		U.S. Bureau of Land Management
CEQA: State 
Lead = State Agency with primary project responsibility 
			California Department of Water Resources
Responsible Agencies 
Trustee Agencies

## Environmental Documents

- EA/EIR Hocker Flat:  Fall 2004
- EA/EIR Canyon Creek Suite:  Spring 2005
- EA/EIR Upstream 10:  Fall/Winter 2006
- EA/EIR Remaining 9:  Fall/Winter 2007
-  MASTER EIR?  - Site specific details
- 			Multiple Neg. Decs.
- 			EA/EIRs

**Notes:**
Canyon Creek:  Need to award by Sept  2005 (for construct 2005-2006 winter) 

Takes funding and optimistic schedule into account.  This schedule matches 3 year implementation schedule.

MASTER EIR COVERS issues like:
Resource categories:  
Land use – project conformance with local and regional plans.
Geology, fluvial geomorphology, and soils – effects on flow and h
Water resources: surface water hydrology and groundwater
Water quality – water conditions from a regional and local perspective (e.g., EPA listed rivers)
Fishery resources – fish populations, their habitats, and harvest of populations
Vegetation wildlife and wetlands: wetland review and ACOE protection
Recreation – Conformance with state and fed W&S rivers & local and policies
socioeconomics, population, and housing (NEPA only) 
tribal trust:  legal interests held in trust for tribes.  Anything that has values (land, minerals, hunting or fishing rights).
cultural resources – effects of project on prehistory, ethnography, and history of area
air quality as measured by stds of N Coast unified air quality management district.
Env. justice – Executive order 12898 Federal actions must address Env. justice in minority populations and low income populations.  & equity of benefits and risks of decisions.
Aesthetics:  based on following local use plans and conform to W&S rivers act.  How is existing visual character to be changed?
Hazardous materials:  materials that may be introduced or currently present on site but effected
Noise
Public services and utilities:  impacts to public services from project
transportation: effects on local transportation plans

## Environmental Permits

- Army Corps of Engineers:  Section 404 Clean Water Act permit
- Endangered Species Compliance:
- National Oceanic & Atmospheric Administration: Fisheries – Biological Opinion
- US Fish & Wildlife Service
- North Coast Regional Water Quality Control Board: Section 401 Water Quality Certification
- California Department of Fish and Game:  Section 1600 Streambed Alteration Agreement
- Trinity County Ordinances:  Floodplain ordinance

**Notes:**
Top 2 = Federal

After Env. Docs, Need permits to do the work.  Some work that is less downstream may increase upstream. 

Now there are permit requirements which are Specific in detail at each site.  
Could combine permit applications
	(permits applications are similar now.  
Could have regional coverage which follow list of permit conditions 
	(e.g., CDFG stream Xing regional permit)

## Environmental Compliance

**Mercury**
- Initial Studies
- Project Impacts to bioavailability & Trinity
**Revegetation**** **
- Balance mitigation vs. function
**Pre-application Meetings**** ****(options to consolidate)**** **
- Timing of construction** **
**Sediment control****	**
**Vegetation removal**

**Notes:**
Hg – Not TMDL listed for Hg fall son EPA stds. for water
	How will restoration effect the availability of HG
Specific Hocker Flat info and Background
Make site specific sampling and implementation recommendations.

Reveg_  There is abundant riparian wetland.  Do we need 1:1 replacement where we are restoring form and function?>  
 Within what distance of disturbance is replacement?
Preserve What values and functions?  

Pre- Apply mtg.  
What are best available operations for vegetation removal or construction ?  
Best season and methods for sediment control?
Options to work on permits as a whole - REGIONAL
