The suburb of Wheaton, Illinois is considering adding another parking garage to its downtown. How does one add a large parking structure to a quaint downtown?

The idea of a parking garage is highly conceptual, one element of a broader study on parking needs, restrictions and the existing inventory downtown. The goal is to stay ahead of parking issues as new businesses take over long-vacant properties and bring more visitors to the shopping and dining district, especially on weekend nights…
City planners say replacing a surface lot behind city hall with a parking garage is a viable option because it’s city-owned property, eliminating the cost of land acquisition. It’s also tucked away from the main downtown arteries but still within walking distance of a Hale Street restaurant row.
Suess said a city hall garage would address neighborhood concerns about overflow parking on residential streets around Memorial Park, a summer magnet that recently underwent a $5 million restoration, the centerpiece of which is a new band shell…
Other council members said they still want to consider another location that’s been floated for a parking structure over the years: the east surface lot of the Wheaton Public Library.
There are practical matters that any community would need to consider: how much parking is needed? What is the cost of the structure? Is this the right location?
There are also bigger questions about what a suburban downtown is supposed to be. Many downtowns would like to have more people visit and spend money in shops, restaurants, and festivals. But, more people and traffic can change the atmosphere. This means more cars. Where to put them?
Parking garages offer a possible solution as multiple stories can pack in more cars than street parking. Wheaton already has a few parking garages so this is not a new idea. But, parking garages are rarely attractive structures. Do they fit in with the surrounding streetscape?
The proposed location above tries to mitigate some of these issues. Wheaton has done this with other parking garages; tuck them behind other buildings so they are not as visible. The proposed garage would be behind City Hall, hiding is from a main stretch of Wesley Street. Yet, it then backs up to residences on the west side, is on a different scale than City Hall to the south, is visible from Memorial Park (site of festivals and events that would drive people to the garage), and is across the street from a school and its green space to the north.
The other proposed site mentioned above has some similar issues. While it would be next to the library on one side and across the street from a multi-story apartment building on the other side, it faces single-family homes on the other side and smaller apartments on another.
Wheaton wants its downtown to exist on a particular scale so that it remains an attractive place for residents and visitors. More broadly, the community protects its character as a quieter, single-family home community (see how a discussion about zoning along a main thoroughfare played out). The city also wants to bring in people and address parking issues which can mar the experience on streets and in nearby residential neighborhoods. Is a four story parking garage the answer? Local leaders and the community will have time to discuss and decide.
