December 2006

State Water Rights Permit Application

June 2008

USACE Section 404 Permit Application

February 2015

USACE Issues Draft Environmental Impact Statement

June 2015 State Water Rights Permit Received – Anticipating 404 Permit in Jan 2016 July 2015

USACE Requires HGM methodology for Mitigation – Delay in expected 404 permit

March 2017

USACE Issues Revised Draft Environmental Impact Statement

• Environmental mitigation on

more than 17,000 acres – Largest permittee- responsible ecological mitigation project in nation – Over 8,500 acres of wetland restoration and enhancement – Planting approx. 5 million trees – Restoring or enhancing over 3,200 acres of native grasslands; 2,600 acres of forests – Improving over 70 miles of local streams

Over 1.23 million trees planted to date (As of March 1)

CLICK TO EDIT MASTER TITLE STYLE PERMITTING REFORM RECOMMENDATIONS

STREAMLINE PERMITTING

• Unnecessary delays from changeover in

people, policies, concepts and procedures – process should only take 2-3 years

STATUTE OF LIMITATIONS TO PERMIT CHALLENGES

• Should be shortened to 180 days vs. 5+ years

to avoid further delays of litigation

FEDERAL FUNDING FOR SUPPLY PROJECTS

• Water supply lowest priority and lowest funded

program of USACE – need Congress to approve more funding and resources

ESTABLISHING PURPOSE & NEED

• Population and demand projections

developed/approved by state should be sufficient

USE OF BEST AVAILABLE INFORMATION

• Applicants shouldn’t be required to

develop new or updated information late in permitting process – recommend statutory deadline.

• Applicant and agencies should have

binding agreement on impact assessment methods required for evaluation.

COMPENSATORY MITIGATION

• Environmental benefits of supply projects

should be considered as offsets to impacts

• Reservoirs are an absolute necessity and we’ve stayed focused on:

– PROTECTING ENVIRONMENT – SMART DEVELOPMENT – PROVIDING ESSENTIAL SERVICES TO NORTH TEXANS… WATER IS LIFE

• Build relationships with state

and federal agencies early

• Assemble dream team – get

right resources/expertise

• Get support from elected
• fficials – keep informed

along the way

• Funded entire $1.6B project

with low interest SWIFT funding from TWDB… saving ~ $230 million Follow our progress at www.BoisdArcLake.org
