The Partnership for Onondaga Creek November 17 th, 2010

A voice for the Midland Community and the environment advocating for better, nonpolluting solutions advocating for better, nonpolluting solutions for Onondaga Creek – Since 2000 Partnership for Onondaga Creek

Environmental Justice Partnership for Onondaga Creek Midland Sewage Plant Green Infrastructure means… Injustice of Midland plant will not be repeated Onondaga Creek & Harbor Brook will be cleaner Community investment and beautification instead of further disruption

Green Infrastructure Solution to capacity problems with underground storage – reduce the rain! Proposed by Onondaga Nation POC: “If you can stop the Armory Sewage Plant, you can stop the Phase III Pipeline too!” County Executive Mahoney has promised that the pipeline will not be built.

During 2008 and 2009 the POC, Syracuse University and SUNY-ESF cooperated to obtain over 200 surveys among five neighborhoods of the Midland and Clinton Sewershed to assess public attitudes toward Green Infrastructure (GI) Implementation.

Explore to what extent individual demographics influence environmental attitudes toward GI Explore at what level neighborhood contexts are statistically related to environmental attitudes toward GI Use maps to visualize environmental attitudes toward GI implementation across neighborhoods * Three building blocks of environmental attitudes: Environmental knowledge Environmental perception Environmental behavioral intention. Objective

Methods---At individual level Summarize responses using descriptive statistics in Minitab software Look for factors that explain responses using regression models in SAS software

Methods---At individual level Summarize responses using Descriptive Statistics in Minitab software Look for influence of demographics, knowledge, perception of benefits and cost on responses using Regression Models in SAS software

Divide survey responses by neighborhood Apply regression models in SAS software to explore the influence of neighborhood context Map predicted responses (from models) across the city using ArcMap Software Methods---At neighborhood level

RESULTS at the Individual Level: The effect of demographic background and perception of benefits and cost on behavioral intention to implement GI if provided for free (216 Individual Surveys) Overall GI (All), rain barrels (RB), trees (T), rain garden (RG), porous driveway/sidewalks (P) and curbside extensions (CE).

RESULTS at the Neighborhood Level: The effect of neighborhood context on respondents’ behavioral intention to implement GI if provided for free (17 block groups with 136 Individual Surveys) Overall GI (All), rain barrels (RB), trees (T), rain garden (RG), porous driveway/sidewalks (P) and curbside extensions (CE).

RESULTS at the Neighborhood Level: The effect of neighborhood context on respondents’ behavioral intention to implement GI if they were to realize savings on their water bill (17 block groups with 136 Individual Surveys) Overall GI (All), rain barrels (RB), trees (T), rain garden (RG), porous driveway/sidewalks (P) and curbside extensions (CE).

Spatial Prediction Model estimation of participation likelihood in overall GI implementation, if free, in Syracuse, NY (10-25: low to high)

Spatial Prediction Model estimation of participation likelihood in overall GI implementation, if savings on water bills were to occur, in Syracuse, NY (10-25: low to high)

Conclusion At the individual level, the likelihood of participation is significantly related to knowledge and perceived benefit of GI. At the neighborhood scale, the variation in willingness to implement any GI, with the exception of curbside extension, can be explained primarily by a higher existing tree canopy cover, a lower percent of African American population, and an older population. The findings can provide valuable information to government officials working to find cheaper, publically acceptable, and environmentally friendly ways to control storm water management.
