Boston has too much parking and too little housing.
Eliminate mandatory minimum parking requirements for all new residential and commercial development. Let builders build homes and businesses instead of forcing them to build parking spaces the City does not need.

IBR - AI Evaluation
WSDOT & ODOT safety engineers have not evaluated IBR's design.
The IBR's Vancouver bridge approach includes a dangerous 1,510-foot S-curve that requires a 35mph truck speed limit.
A -3% grade plus frequent rain and black ice make a safe speed even lower.

Bob Ortblad emailed WA and OR state safety engineers about IBR's icy S-curve approach — zero response. He says an immersed tunnel would be safer, cheaper, and faster. clarkcountytoday.com/opinion… #IBR #Transportation #Opinion

The four ingredients of a great neighborhood
1. Mixed Uses
Mixing homes offices, and retail keeps the neighborhood full of energy throughout the day. Someone always has a reason to be there
2. Short blocks
People are encouraged to explore different routes to and from their destinations. The result is lots of lively streets instead of one main boulevard
3. Different ages of buildings
Older buildings are cheaper, perfect for affordable housing and startup businesses. Newer buildings are more expensive, perfect for luxury homes and established businesses. The magic is in the mix
4. Density
In the end, it’s the people that make a neighborhood vibrant. More people, more fun

😵💫I-5 BRIDGE - Interstate Bridge Replacement Project’s (IBR) administrator – who’s just announced his resignation – admitted that IBR is “basically the same” project that failed a decade ago, but in the process, he’s spent $273 million on consultants, with more than 40 percent that money ($116 million) going to his former employer, WSP USA. clarkcountytoday.com/opinion…

Important truth bomb: Developers don't pay for inclusionary zoning. Renters do.
The Interstate Bridge Replacement Project (IBR): 2 years behind schedule, likely increasing in cost to $9-10 billion, at risk of losing $2.1 billion in federal grants & is too low to be approved by the Coast Guard. Plus: its director just resigned. cityobservatory.org/lars-lar…

NYC housing will never be affordable
You have easily 30 million people in this country that would move to NYC the second it came within any range of their current cost of living

Why should New Yorkers on bikes be harassed, ticketed, or given criminal summonses for traveling 16 mph, when the driver of a vehicle that weighs 80x as much doesn't even receive a ticket for traveling 35 mph?
This is a nonsensical, backward policy — not any real solution.
Starting TODAY, a new 15 MPH speed limit is in effect for e-bikes!
More and more New Yorkers are using them, and we’re grateful to @NYC_DOT for their efforts to keep our streets safe for everyone.
Ride safe, everyone!

FD culture is “two hundred years of tradition unburdened by progress.” Unfortunately, they are also unburdened by data, evidence and the ability to weigh trade offs. The US has ~5 times the fire fatality rate of peer nations with narrow streets, small fire trucks & single stair.

City Observatory retweeted
The ratio of US car crash injuries to fire injuries is 225:1. For deaths, that number is ~11:1. Yet fire departments are often foes of safer streets and require they be optimized for 15-ton trucks at speed. Other nations have small trucks, narrow streets and fewer fire deaths.

This is a great idea for the *entire* building industry. The fact nearly every home, building etc in America is a one-off, bespoke, site specific project that is not allowed to use most of the land it sits on is insane and a policy designed in a lab to make housing expensive.

In ideal urban construction market, owners can select from a menu of buildings, and have prefabbed “stone kits” delivered to site for assembly @mspringut

We have granted cars, stronger rights to housing, space, mobility, and safety than we have given to people.
This inversion is at the heart of what is wrong with American transportation which she metes out more injury and death to young people than any other cause. By far.
