The city of Pacific has several subdivisions and residential areas most of which, except the old town areas, are separated geographically by wooded or commerce areas. Sidewalks do not connect most of the subdivisions or city areas. These areas include; North Old Town, South Old Town, The Hawthorne Subdivision, The Hogan subdivision, The Monroe Woods area, Osage Hills, Glen Forest Estates, Hidden Hills Estates, Silver Lake Estates, and the Thornton road area.
The old town area is split by the railroad into a North and South division. The entire old town area is quite historic with most of the homes built in the mid to late 1800's into the early 1900's. The homes in the south division are somewhat older and more modest than the north division. The northern area is rich in historic architecture mostly of residences of Folk Victorian, Queen Anne Victorian, 1.5 - 2 story double pen house vernacular homes with high style influences, and French vernacular designs many retaining their tin roofs. The south section is ripe with German vernacular styles, one story double pen house types, upright and wing vernacular types, Folk Victorian, American Four Square, and the few Missouri shotgun style homes are located in this area. The northern area is lined with modern attached homes along its northernmost edge. Several trailer homes are located in the southern division.
