It’s a multifaceted issue. Not just metro.

With more density, you have more demand for metro, yes. The above poster thinks that pressures from these residents could improve the metro. I agree with him but I understand your hesitations.

But there’s also two street cars lines here. That’s a significant mode of transit. Not to mention buses.

But more importantly, more density means that there is more likely to be things to do and places to be and stores to shop at within walking or biking distance, which means you won’t need to depend on the Metro as much anyway.

It also means the surrounding areas will get the second-hand-smoke benefit of improving just because they either use the land to make money off of the new population, or the sell it to someone who will, which means the nice and enjoyable areas increase in size, compounding the above point.

This can all be guided by good zoning practice. Parking is only part of the equation if the math is how to trend towards 0 parking spots in this neighborhood.
