I. Stormwater Overview 
Stormwater Management Goal 
Prevent degradation of water and sediment
quality from Port operations through effective
and efficient compliance required by Industrial,
Municipal and other NPDES permits. 
Collaborate, coordinate and provide technical
assistance to tenants to assist in achieving
tenant stormwater compliance.

NPDES = National Polluant Discharge Elimination System                3

Requires the Port to Create and Implement a
Stormwater Management Program (SWMP) 
Nine required elements 
Yearly management and monitoring costs  Seaport, Real

Permits 
70% of our properties are also covered by
Tenant Industrial Stormwater permit (ISGP) 
Permits issued to tenants

IV. Costs 
Phase I Permit Required Stormwater Management Program (SWMP) 
For Seaport, Real Estate equals ~ $ 1.0 M/ Year 
Operation and Maintenance on Port Properties ~ $ 500k/year 
CIP Estimates - 2011 to 2016 
Redevelopment Projects 
Stormwater upgrades (T 10 & T 25) ~ $ 1M 
Port Miscellaneous pavement projects ~ $ 1 M/year 
Terminal ISGP Stormwater Improvements 
Corrective Action could cost $ 20 to 35 M 
Timeframe = 2014 to 2016 
Retrofitting 
This would require installing stormwater treatment for
properties that don't currently have it.
