The old Bluemeyer public housing project was a combination of high-rise and low-rise buildings, all fairly disconnected from each other and the adjacent public streets.

October 2006
The entire complex was razed( in a few phases) and the replacement project is nearing completion. The map below shows the project area:

Everything inside the shaded area is new. Everything from underground infrastructure to the buildings to the street grid, curbs sidewalks and curb ramps. McCormack Baron Salazar had a clean slate to work with. Here is how they summarize the project:
Renaissance Place at Grand | St. Louis, MO
402 units
Total Development Investment $68,792,300
The Arthur Blumeyer public housing development, constructed in 1968, consisted of four high-rise and 42 low-rise buildings and housed 1,162 families, including 585 elderly. The development is located north of Grand Center, the mid-town arts district in Saint Louis.
The Federal Omnibus Consolidated Reconciliation Act of 1996 requires that viability assessments be performed for public housing projects of 300 or more units with vacancy rates of 10 percent or higher. This law requires units to be removed from the housing stock within five years if public housing costs exceed the cost of housing vouchers and if long-term viability of the subject property cannot be assured through reasonable revitalization plan. In 1999, Blumeyer’s two elderly high-rise buildings, 174 of the family townhouses and both of the family high rises were declared non-viable by HUD.
The St. Louis Housing Authority took the opportunity to collaborate with the larger community, and elected to pursue a strategy of transformation through HUD’s HOPE VI program. The application submission was successful and the Blumeyer public housing site was awarded $35,000,000 in HOPE VI grant funds.
Overall the new project is quite nice.

Above is one of the new street intersections, Franklin Ave & Josephine Baker Ave (map). I’ve drawn lines to show the path at the intersection that an able-bodied person would walk — a straight line. No surprise. While walking with my cane I’d follow the same path as well — dealing with the curbs is preferable to the longer distance required to use the ramps.
But what if you use a wheelchair or mobility scooter? Keep in mind that the 1st floor units are accessible. The other day I saw two different residents using mobility scoters in the area. So the disabled are expected in the immediate area.

Above is the same intersection with one path for wheelchair/scooter users shown in red. Rather than being able to continue in a staright line the disabled must angle out and cross one street while being very close with traffic going parallel.
This intersection needed twice the number of ramps so that a straight path could be maintained. Rather than a single ramp out at the corners each quadrant would have two ramps – one per direction of travel. Keep in mind that the entire intersection is new. We are not talking about the expense to retrofit the intersection with 8 vs 4 ramps. The additional cost would have been minimal when this was done from scratch.

Same situation at another intersection

I just love the mis-match of ramps crossing Theresa parallel to Delmar.
In St. Louis and other cities retrofit ramps are often placed at the corners. As cities were retrofitting ramps following the passage of the Americans with Disabilities Act of 1990 they had limited budgets. Doing four ramps per corner was faster and cheaper than eight. Additionally, obstacles like sewer inlets prevent more ideal placement of ramps. The corner ramp was a valid retrofit compromise.
But in new construction the corner ramps are unacceptable. There is no excuse for the way the ramps were placed in the above project. None. I’d like to see a public flogging of the engineers that designed these streets, sidewalks and ramps. Better yet, they should have to live here and use a wheelchair to get around!
It may be too late but the city should not accept these streets from the developer. Someone’s Errors & Omissions insurance policy should pay to correct these ramps.
