5.0 NATURAL FEATURES Vegetation and Contour The diagram on the left shows the contour and vegetation on the site. The site has an irregular contour which needs to be sustained as part of the preservation of the historic ruins on the site. This irregularity can lead to the site being not wheelchair friendly enough, even though a wheelchair access is provided to the site through the St. Nicholas Walk. When we look into the Vegetation, it can be observed that they are concentrated towards the North east side of the site. Some scattered vegetation can be seen on the northwest and southwest ends. The site is adequately buffered from the Welles Street on the North by the medium canopy trees along the borders.

However, the site is completely exposed on the south side to the busiest road around it, and lacks any type of buffering. This can lead to the site experiencing more noise pollution from the A47 road.
Drainage Sewer drains can be observed along the west, south and east sides of the site. The highest point in the site is at the northwest corner, hence the rainwater runoff will happen from the northwest to the southeast. The highest point of the surrounding however is at the southeast end of the site. Therefore the surface drainage flow occurs from south east to north and southeast to west from the A47.
