This document provides an overview and update on the Bois d'Arc Lake water supply project being undertaken by the North Texas Municipal Water District. The key points are:
1) Population growth in the region is driving the need for new water supplies to meet future demand projections of 3.7 million people by 2070.
2) The $1.6 billion Bois d'Arc Lake project will provide a new reservoir with a firm yield of 108 million gallons per day, with construction starting in 2018 and water delivery expected by 2022.
3) Extensive permitting and mitigation efforts were required, including over 17,000 acres set aside for wetland and habitat restoration. Construction is now underway on various

11. CLICK TO EDIT MASTER TITLE STYLEPERMITTING 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
officials – keep informed
along the way
• Funded entire $1.6B project
with low interest SWIFT
funding from TWDB… saving
~ $230 million
