The <strong>Elizabeth</strong> <strong>River</strong> Project<br />
- 15 years <strong>of</strong> river restoration -<br />
Mission: Restore <strong>the</strong> <strong>Elizabeth</strong> <strong>River</strong> to <strong>the</strong> highest<br />
practical level <strong>of</strong> environmental quality with<br />
government, bus<strong>in</strong>ess, & community partnerships.
‣ Establish partnerships between<br />
government, bus<strong>in</strong>esses and<br />
citizens to achieve real<br />
environmental results<br />
‣ Today: 2,000 members, 59<br />
<strong>in</strong>dustries, four cities, state and<br />

Watershed Action Plan<br />
‣ One <strong>of</strong> <strong>the</strong> 1 st Sub-Watershed<br />
Plans completed on <strong>the</strong> Bay<br />
(1996)<br />
‣ Focused efforts on priority<br />
actions that will make <strong>the</strong> most<br />
difference<br />
‣ Developed with 120<br />
stakeholders from government,<br />
science, citizen groups and<br />

• Action 2-Restore 2<br />
& conserve<br />
10 miles <strong>of</strong> river corridors<br />

Project Issues to be Addressed<br />
• Permanent lost <strong>of</strong> river bottom<br />
• Permanent lost <strong>of</strong> wetlands and sand beach<br />
habitat<br />
• Upland owners could become land locked<br />
• Possible structural issues with cut<strong>of</strong>f wall
Lessons Learned From <strong>the</strong> Money<br />
1) Community consensus on<br />
a sediment remediation,<br />
however long and difficult<br />
this process may seem, can<br />
be a powerful foundation.<br />
Po<strong>in</strong>t Project<br />
2) If you want your project<br />
implemented, you must sit<br />
at <strong>the</strong> table with everyone,<br />
especially anyone who<br />
could stop you – and listen.
Lessons learned – Local Involvement<br />
3) Don’t be afraid<br />
to collaborate<br />
with players<br />
who have a long<br />
way to go. They<br />
have <strong>the</strong> greatest<br />
potential to<br />
improve <strong>the</strong><br />
watershed.
