If you are looking for safety then you are fine. I would be worried about the area across New Hampshire. Considering the tax rate is so high for TPK, unless I was zoned for TPK Elementary School, I wouln't move there.
If you are going to pay the same high tax rate as those that are zoned for TPKES, then you might was well move to that section of TPK. Otherwise, for the money, you could get in the nicer areas of Silver Spring with a better elementary.
Yet another DCUM "authority" on Takoma Park who doesn't know what they are talking about. I live east of NH and our entire neighborhood is zoned for TPES.
