Conventional Storm Water Management
Does not view water as a resource Moves water quickly from Point A –
Point B

The problem with “Hydraulic Efficiency” Connection to the piped system, gutters, etc. quickly transports
water, sediment and other pollutants to our streams and ocean Development practices, impervious surfaces, detention ponds,
don’t replace nature’s ability to attenuate pollution or infiltrate water
Dealing with water but not the impacts to resources

Case study: Koʻolaupoko Low-Impact Retrofits
Similar LID techniques can be incorporated into Low-Impact Retrofits (LIR) D: defined as landscape features which use green
infrastructure principles and ideas to manage storm water within a confined urban space.
Address conventional development practices Gain some pre-development hydrology Pollution reduction Demonstration projects

Urban Sub-basin Action Plan Assess urban areas and other developed land that
contribute to non-point source pollution in Koʻolaupoko using ecologically-based metrics to identify and prioritized opportunities for LIR implementation.
USBAP shall inform and guide the implementation of projects to restore to the fullest extent possible a site’s pre-development hydrology and address pollutant by using design techniques that infiltrate, filter, store, evaporate and detain runoff as close to its source as possible

Benefits of LIR Demonstration Aesthetics Reduction of NPS runoff In Kāneʻohe, ~ 41 gals of water annually can be
infiltrated for every 1 sq. ft. of impervious surface removed

What is a Rain Garden? A rain garden is a constructed depression planted with native or non-invasive vegetation that allows storm water from impervious surfaces such as roofs and driveways, to collect, briefly store and then infiltrate into the groundwater.
Overflow Roof runoff Infiltration

Rain Garden Construction Infiltration, Sizing & Setbacks
Infiltration is the most important aspect: minimum 1/2” per hour of infiltration
~10% sizing of Contributing Drainage Area

They are not a pond or a water feature Water is meant to drain within 24-36 hours This is not enough time for mosquitoes to breed
They are not designed to be built where water currently ponds
