Constructed Wetland

An engineered system designed to simulate natural wetland functions for water purifications. Essentially a treatment system that removes contaminants from wastwaters.

Promote runoff of precipitation volumes instead of infiltration into the subsurface. The imperviousness or degree of runoff potential can be estimated for different surface materials.

Phase II Environmental Site Assesment.

Good commercial and customary practices in conducting a Phase II environmental site assessment, with respect to the potential presence of contaminants. 

Standard test method for total normal emittance of surfaces using inspection meter techniques.

How to measure total normal emittance of surfaces using a portable inspection meter instruments. 

(RP= reccomended practices)

Provides general exterior lighting designguidance and acts as alink to other IESNA outdoor lighting reccomended practices. Covers community lighting, glare, etc. 

American National Standard Institute

Concerned with helping to assure the safety and health of consumers and the protection of the environment. 

(KL)    Indicates the volume of water lost via evapotranspiration and is dependent on the landscape species, the microclimate, and the planting density.

KL= ks x kd x kmc 

Defined by the UPC in:

Appedix G as "untreated household waste water which has not come into contact with toilet waste..."

Appedix C as "waste water discharged from lavatories, bathtubs, showers, clothes washers, and laundry sinks."

Some state and local authorities allow kitchen sink wastewater to be included.

Brownfield Redevelopment (1/2 point)

Rehabilitate damaged sites where development is complicated by real or perceived environmental contamination, reducing pressure on undeveloped land.

Encourage tenants to select buildings with best practices systems and employed green strategies.

-Provide the LEED-CI Letter Template signed by responsible party declaring that the project is located in a LEED certified building.

-Provide a copy of the core building LEED certification document.

- A building developed on a site documented (by means of ASTM E1903-97 Phase II)

 OR

- A building on a site that has been classified as a Brownfield by a local, state, or federal government agency. Effective remediation of site contamination must have been completed.

- Provide a copy of pertinent sections of ASTM E1903-97 OR provide a letter from a local, state, or federal agency confirming Brownfield classification.

- Provide the LEED Letter Template, signed by the civil engineer or responsible party, declaring the type of damage that existed on the site and describing th remediation performed.

Stormwater Management: Rate and Quantity

(1/2 point)

Limit disruption and pollution of natural water flows by managing stormwater runoff.

A building that prior to development had:

< or = to 50% imperviousness and has implemented a stormwater management plan that = or < the predeveloped 1.5 year/24 hour rate and quantity discharge.

OR

If > 50% imperviousness has implemented a stormwater management plan that reduced pre-developed 1.5 year/24 hour rate and quantity discharge by 25% of the annual stormwater load falling on site. This mitigation can be through a variety of measures including perviousness of site, stormwater retention pnds, capture of rainwater for reuse or other measures.

Provide the LEED Letter Template, signed by the civil engineer or responsible party, declaring that all pertinent credit requirements are met.

Stormwater Management, Treatment

(1/2 point) 

Limit disruption of natural water flows by eliminating stormwater runoff, increasing one-site infiltration and eliminating contaminants.

-A building that has in place site stormwater treatment systems designed to remove 80% of the average annual site area TSS and 40% of the average annual site area TP.

- These values are based on the average annual loadings from all storms < or = to the 2 year/24 hour storm. The building must implement and maintain BMPs outlines in Ch.4, part II of the EPA's Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters, January 1993, or the local government's BMP document, whichever is more stringent.

Best Management Practices

Heat Island Reduction, Non-Roof

(up to 1 point)

Reduce heat islands (thermal gradient differences between developed and undeveloped areas) to minimize impact on microclimate and human and wildlife habitat.

A building that provides shade or will have within 5 years of construction) and/or uses light-colored/high-albedo materials with a SRI of at least 30, and/or open grid pavement, that individually or in total equals at leat 30% of the site's non-roof imperviousness surfaces, which include parking areas, walkways, plazas, firelanes, etc.

OR

Has placed a min. 50% of parking spaces underground or covered by structured parking.

OR

Used an open-grid pavement system (<50% imperviousness) for 50% of the parking lot areas.

Provide the LEED Letter Template, signed by the civil engineer or responsible party, referencing the site plan to demonstrate areas of paving, landscaping (list species), and building footprint and declaring that they meet one of the three requirements.

-Select space in a building that is located in an established, walkable community with a minimum density of 60,000 sf per acre net (two-story downtown development).

OR

-Select space in a building that is located within 1/2 mile of a residential zone or neighborhood (with an average density of 10 unites per acre net).
