STATUS QUO PATTERN Site Geometry and Infrastructure	Back
This aerial photograph illustrates the Status Quo Pattern study site as it exists today.  A simplified depiction of site infrastructure is superimposed.  Joint utility trenches are shown in a dashed yellow line; water lines are shown in a light blue line; storm sewers are shown in a solid dark blue line with catchbasins indicated by small, dark blue squares; sanitary sewer lines are shown in a solid olive line;  property lines are shown in a dot-dashed red line; building front setbacks in a solid orange line; curbs in a solid purple line; sidewalks in a sloid green line; driveways in a  dashed green line; and gravel shoulders in a dashed purple line.  Of the total site 46% is permeable surface of lawn and planting bed; 29% is covered by house, storage, and garage structures; and 25% is paved sidewalk and road.  Paved driveways, absent in the Traditional Pattern but prevalent here, account for 10% of the paved surface on the site.   Location Newton, Surrey Size 0.03 sq.km 3.0 ha 7.4 acres Population Total  consequent to this pattern 2500 people/sq.km Density 10 d.u./ha 4.4 d.u./acre Permeability & Coverage (site) Pavement 25% Roofs 29% Total Pavement 229 sq.m/d.u.
