<br />e <br /> <br />Coincident Tabulation <br /> <br />The coincident tabulation is a first level of analysis and is comprised of a data display <br />cataloging of change, The concept is to track changes in watershed land use coincident <br />with an environmental interpretation of the watershed. The coincident analysis may be <br />performed between any pairs of data in the file for any areal subdivision (such as sub- <br />basins or damage reaches)_ Table 5 is a coincident tabulation for the existing and 1990 <br />land use conditions for damage reach No.2. <br /> <br />. <br /> <br /> TABLE 5_ Land Use Coincidents Damage Reach 2, Trail Creek. <br /> 1990 LAND USE - (Acres) <br /> I 2 3 4 5 6 7 8 9 10 TOTAL <br /> 106 6 41 27 92 272 <br /> 2 <br /> 3 3 <br /> 4 <br />EXISTING 5 <br />LAND USE <br />(Acres) 6 6 6 8 20 <br /> 7 5 14 4 23 e <br /> 8 <br /> 9 24 2 tl 9 24 70 <br /> 10 <br />TOTAL 141 11 72 36 128 <br />ROW AND COLUMN LEGEND, <br />1) Natural Vegetation 6) Agriculture <br />2) Developed Open Space 7) Industrial <br />3) Low Density Housing 8) Commercial <br />4) Medium Density Housing 9) Pasture <br />5) HiBh Density Housing 10) Waterbody <br /> <br />The values displayed in the figure are the number of acres which are coincident with <br />the row and column categories_ The diagonal values in the matrix are the number of <br />acres which have not changed land use classification from the existing condition to the <br />1990 alternative future condition. For example, in row one, 106 acres that were classi- <br />fied as natunl vegetation under existing conditions remain so classified under 1990 con. <br />ditions, 6 aCles of land classified as natural vegetation under existing conditions are con~ <br />verted to medium density residential use, etc_ The total amount of land classified as <br /> <br />. <br /> <br />;. <br /> <br />14 <br /> <br />e <br />
