ENVIRONMEMIAL <br /> Decatur, IL <br /> SSWVIICES® <br /> e. Percent Rainfall Ingress — To enable a comparison of RDII severity between basins of <br /> differing sizes (in the future), the net RDII volume for the basin (as defined by the flow <br /> monitoring location)will be"normalized". This means that the volume of RDII was divided <br /> by rainfall(inches)and by basin size(in acres or lineal feet(If)of pipe)to enable an apples- <br /> to-apples comparison of results among basins. Basin linear footage information will be <br /> calculated using the City's GIS data. The rainfall data are to be obtained from installed <br /> rain gauges for this project. <br /> f. Ranking of RDII Severity in Each Target Area using Normalized Values. <br /> g. GIS Based RDII Severity Maps for each basin and sub Basin based off the Normalized RDII <br /> Values and Capture Coefficient determined at each monitoring location (RDII/Acre). <br /> h. Recommending the next step(s)for RDII removal. <br /> Owner Activities: Owner(and consultants) agrees to perform the following functions in connection with <br /> this project.
