Permeable concrete SFMTA bus pads and Permeable stormwater basins
Permeable concrete SFMTA bus pads and Permeable stormwater basins
The idea is that SFMTA in places permeable concrete bus pads and permeable concrete square pads in front of all storm drains
This simple idea may be much cheaper than any other method of recharging groundwater
let’s take the corner of Eddy and Taylor as an example this bus stop is SFMTA # 14493. We in place a 30 square meter permeable concrete bus pad here replacing the street asphalt. It might be 10 meters by 3 meters.

This would collect 442 gallons of rainwater per year but this is not true it would collect most of the rain from the gutter that drains the surrounding sidewalks and streets!
So the street and sidewalks from the corner of Eddy and Taylor down to Eddy and Mason is 13 meters by 150 meters This is 30,000 gallons a year
