Are those what I think they are (topographical contour lines)...? [Puts in me eyes, enlarges pic, and squints

] Ok, 1-foot contour intervals, that's not so bad.
But yes, urban-style density in isolation from urban infrastructure/jobs/amenities doesn't seem all that great. What's nearby? Are there any jobs/stores/schools within walking distance? Is there public water/sewer? Is there a bus line stopping at or near the entrance (and what's the service quality/frequency, what's it connect to, and how far away are all the destinations)? As for the size, what's the price of these expected to be, vs. the prices of existing housing in the area and other new housing going up (if any)? "Houselet" is better than "homeless". So many questions...
Did it get approved? Were any changes required before approval?
