Stormwater re-leaf

Studies at Cornell University show that combining the use of structural soils and porous pavements increases water recharge into the soil to aid in tree-root growth and decreases stormwater runoff. In Tree-Friendly Technologies for Stormwater Management (Monday, Sept. 11, 10 to 10:50 a.m.), Cornell professors Nina Bassuk and Peter Trowbridge will discuss how agencies can create a stormwater management plan that effectively and safely integrates trees and paved surfaces without creating pavement failures.

In order to track compliance at several construction sites, a group of neighboring communities implemented a common permitting system that uses a database, geographic information system, and global positioning system. During the session Make Erosion Control Inspections More Efficient With Technology (Wednesday, Sept. 13, 8:30 to 9:20 a.m.), learn how the communities used this system to streamline the inspection process, customize reports, and share information.

Sunday, Sept. 10, 3 to 3:50 p.m.

Hear real-world examples of design techniques like inlet filters, wattles, erosion-control blankets, and bioswales, and learn cost-effective ways to implement these techniques. Monday, Sept. 11, 11 to 11:50 a.m.

This session explores issues involved in crafting a rate structure that equitably allocates costs to customers and factors in the stormwater services they receive. Learn how to avoid legal challenges and implement a legally defensible basis for credits to customers that deploy stormwater best management practices.

Tuesday, Sept. 12, 1 to 2:15 p.m.

National Pollutant Discharge Elimination System regulations require PW staff to complete activities throughout the year to meet pre-set goals. Attend this session and learn how to harness Web portal technology to streamline these efforts.

Monday, Sept. 11, 3 to 4:30 p.m.

Representatives from three different parts of the country will discuss their regional cooperative efforts to address stormwater quality issues. Their stories will include aggressive tactics to control fecal coliform bacteria, water quality and stream bank protection, and a sustainable stormwater management system.

Optimizer is a small, efficient stormwater runoff system with a flow-control device that uses a pressure head to immediately discharge at the maximum allowable rate, reducing required storage volume. Its small size requires less excavation and backfill than larger systems, reducing installation time and cost. www.contech-cpi.com.
