Where does your home fall on the Sustainable Development Area map?

In the early days of Complete Communities, the City of San Diego mistakenly approved a project that was outside the boundary of the "Transit Priority Area" (TPA) required by the ordinance. Thereafter, the Sustainable Development Area (SDA) was suddenly created, perhaps to justify the City's erroneous approval of the project.


What is the TPA?

The TPA map defined where dense development is allowed in San Diego. But instead of using a rational, half-mile walking distance to transit as its metric (which was the intention of state legislation), San Diego chose to use a half-mile as the crow flies from transit.


This new measurement scheme increased the distance from transit up to 3 miles away from transit into un-walkable neighborhoods that were across freeways and over canyons. To make matters worse, the maps are not only based on existing transit stops but also planned transit stops — that may never be built.


Behold, the un-sustainable SDA

In response to criticism, the City reconfigured this map and in the ultimate oxymoron, called the new map the Sustainable Development Area (SDA) in which they used walking distance up to one mile away from transit (or further in some cases). You can find articles on this (unsustainable) SDA in our Email Archive, or click here to read the analysis we submitted to the City Council.

As a result of the SDA, approximately 5,224 more developable acres are now available to developers compared to the current TPA. For residential neighborhoods, this means that 4,612 more developable acres are now eligible for the Bonus ADU program than what was previously developable under the TPA.

To plan for reality you must be data-driven...

of people who use transit live within a 1/2 mile walking distance.

Thanks to Mayor Gloria and his Planning Department, developers can now purchase single-family zoned homes up to a mile away from transit — either existing or planned — and turn them into high-density apartment complexes, even though federal, state, local, and academic studies show that most people will not use transit if farther away than a half-mile walk.


The Planning Department relies on residents thinking that they won’t be affected by regulations that target single-family neighborhoods, and the Sustainable Development Area (SDA) is another one of these ruses.
