Stormwater Management“Retain, infiltrate and/or harvest the first .5” of rain that falls on site within 24-hour period, or all stormwater for one year, on site or adjacent site(s) so that no stormwater is discharged to drain/inlets”

Stormwater Management in Neighborhood Revitalization Helpful solutions to solve problems with old & deteriorated existing infrastructure reduce or eliminate flooding
from runoff and sedimentation reduce/eliminate standing
water recycle rainwater
May help jumpstart revitalization projects that don’t require a market to be created
Economic development – can help create new jobs

From “Enterprise Green Communities Cost Benefit Study”, 2009
In fact, tradeoffs between cost expenditures and financial savings underscore the importance of executing an integrated design approach.
Focusing on the design elements, such as orientation of the housing, location of the windows and optimization of daylight into the housing, can lead to less expensive mechanical and electrical system purchases, allowing room in the budget for other measures such as healthier building materials.

“Green” Jobs• Deconstruction and recycling of material for restored and new buildings
• Training neighborhood residents to install green landscape infrastructure
• Training residents how to maintain new infrastructure
• Creating local nursery to grow plant materials that could be used for landscaping

Rain gardens at front and side edges of property
Deciduous shade tree on the W side of the house blocks hot summer sun, but allows warm winter sun to penetrate
Evergreen plants on NW side of the house to block cold winter winds
Permeable walk allows water to be absorb directly in the ground

Westside TAD Strategic Implementation Plan
The Historic Mims Park Initiative is led by the National Monument Foundation.
Property was purchased by the city of Atlanta after the area flooded in 2002
Project includes: lake/water retention pond to mitigate flooding on site, urban farm, greenhouses, playground, the Farmers’ Market, and a Center for Tourism among others.
Approximately 160 jobs will be created
