*4.2.2 Surveillance of the neighbourhood*

The study shows that looking at the first indicator of this element, which has to do with the placement of windows to overlook sidewalks; Agodi GRA had highest with an index of 3.4 while KIS and ALGRA do not seem to have their windows

placed in such a way as to overlook sidewalks with an index of 2.6. The average values of this index also seem to confirm the fact that the ability to overlook sidewalks may not be a primary consideration during the design and construction of most of the units in the study areas. Considering the height of the fence to permit surveillance in the neighbourhoods, Agodi GRA and NBS has the highest index of 4.2 while KIS is the least at 2.6. **Figures 5** and **6** shows pictures of security gate and guardhouse, exits gate under lock and key. In the case of external light to eliminate blind spots, OBS seems to fare better than all the other neighbourhoods with an index of 3.6 while NBS does not seem to enjoy much of external lighting and thus the least index of 1.8 (see **Table 5**) But for vehicular traffic, OBS seems to enjoy a sizable amount over and above the others with an index of 3.8 while NBS seems to have the least with an index of 2.2. This may be explained by the fact that OBS is surrounded by an impressive network of important roads, signage, derelict gate, school, abandon building and street view and an enclosed street and view of exits gate and security guide house and avenues in the area as evidence in **Figures 7**–**15**.

In the case of surveillance potential of land use, **Table 5** shows that NBS seems to have the advantage with an index of 3.6 while OBS and ALGRA did not seem to do well at an index of 3.0. However, the proximity of the indices around an average 3.0 shows that the study areas are not far apart from each other and that they did not do too badly especially as the least is 3.0. Considering the level of commercial activities in or near a neighbourhood in the study areas, OBS and NBS seem to take the upper

hand with an index of 5.0 each while KIS takes the rear with an index of 2.8. This shows that even though all the study areas enjoyed some level of commercial activities, OBS and NBS are exceptional. In terms of quality of surveillance, which is exemplified by the number of eyes on the street OBS and NBS again take the lead with an index of 4.0 while KIS again brings up the rear at 2.0. In summary, NBS seems to have the highest index of surveillance with a value of 3.74. The highest contributor to this being the type of Level of commercial activities in or near neighbourhood at a value of 5.0 while KIS seems to have the least index of surveillance at 2.80, the biggest contributor to this being the level of Surveillance potential of land use in or around the units with a value of 3.4 OBS, Agodi GRA and ALGRA seems to be strong on surveillance in their units.
