Comprehensive Approach to Sustainability Georgia Tech as a Living Learning Laboratory Education: Learning in the Classroom Research: Discovery in the Laboratory Campus: Practice in Managing our Campus
Campus Master Plan Education Technologically appropriate learning spaces Research neighborhoods to promote inter-disciplinary learning Open spaces for recreation Ecology Green buildings Native vegetation systems Reduce impervious surface Environmental Stewardship Sustainability Economy Effective use of Physical and Fiscal Resources Historic Districts
Campus Historic Preservation Master Plan
Key Concepts: Ecological Landscape Human Landscape Goals: Develop integrated, ecologically-based landscape and open space systems (storm water management). Enhance living, working and learning environment. Unify the campus with a distinct sense of place. Increase tree canopy, replace aging trees Create an Eco- Commons (80 acres) Implement ecological performance requirements of 50% reduction of storm water runoff Landscape Master Plan
Cistern Master Plan 40,000 gallon 280,000 gallon Athletic Precinct Clough Commons Cistern: - 1.4M gallon cistern capacity - 28 day supply for irrigation - 28 day supply for toilet flushing - 30% reduction in stormwater

Stormwater Master Plan - Goals Promote campus sustainability: Rainwater harvesting Reduce stormwater runoff, which contributes to City of Atlanta combined sewer Create visible campus amenities that functionally contribute to stormwater management Exceed newly adopted City of Atlanta stormwater regulations
Stormwater Master Plan
Phase I - Coordinate with Campus Development Projects Infiltration Cells Infiltration Cells
Stamps Field 3.75 acres synthetic turf, $4.5m total construction cost, $565,500 stormwater costs
Stamps Field Infiltration areas Infiltration Cell Drainage Grid Infiltration Cell To City Sewer
Phase 1 - Construction Provides 44,500 Cubic Feet (332,000 Gal) of Stormwater Infiltration Volume Over 9.5 times the City of Atlanta requirements. Provides storage for future development Provides flow reductions for projects with insufficient land area to meet city requirements (campus-wide approach)
1.4m Gallon Cistern water for toilet flushing, irrigation for approximately 13 ac water for the Campanile Fountain manages stormwater for 22.5 ac
Augmented Reality
Volume Reduction with Stormwater Master Plan (average rainfall year) 70 Million Gallon Reduction (40% of Total) 23% Irrigation (16 MG) 61% 16% Toilet Flushing (11MG) Infiltration (43 MG) Translates to over $140,000 savings for the City in annual treatment cost by reducing unbilled stormwater in the combined system Reducing stormwater contributions to the City s combined sewer extends benefit to a community that is fighting to reduce sewer spills to the streams (under EPA consent decree)
Investment Strategy (the long view) Comprehensive Campus-wide Approach vs. Project-by-Project Basis Probable Costs of 25 year Build-out Without Stormwater Master Plan Irrigation $3.3 M Domestic water/sewer $14.1 M Cistern/Detention $10.9 M $28.3 M City Requires Volume reduction = 0.2 MG Rate reduction volume = 2.2 MG With Stormwater Management Plan Irrigation $0 Domestic water/sewer $11.9 M Irrig./Stormwater Cisterns $9.8 M Clean Water Cisterns $5.3 M Infiltration & Raingardens $1.4 M $28.4 M Assumptions: 4% inflation rate, 4% discount rate Domestic water & sewer in future buildings ONLY Cistern/Detentions to meet City requirements Master Plan Provides Volume reduction = 1.9 MG Rate reduction volume = 2.6 MG 9.5 x City Requirement for Volume reduction
