Eau Claire: Dormers

 Dormers characterize multi-story houses, regardless of age, yet most of these houses are found in the older sections of Eau Claire.  In single-story houses, dormers are absent!  In 1980 - 1990s dormers are used for the first time as mere decoration, previously dormers were functional: adding space, light, and ventilation to attics. Other types of windows are Bay, Picture, and Normal.
Can you tell where the older sections of Eau Claire are by examining the distribution of dormers on this map?
