As a result, you could probably keep the noise limited contour for VHF-LO about the same but reduce the urban contour by 20 or 30 dB (on the map I would have the urban contour include the old cities of Ottawa, Nepean and Gloucester, but exclude Kanata and Orleans).
Since the contours are used for official planning, I left them alone. The Longley-Rice maps are adjusted downward though. 5 dB for high-VHF, 13 dB for low-VHF.
