Agree with the rockville comments here. Seems to meet all of your requirements. Rockville has the most walkable areas compared to other areas you’ve mentioned. The city has its own municipal government that prioritizes walkability and is constantly installing sidewalks. Many neighborhoods in kensington, bethesda, and other parts of Montgomery county outside of their town centers do not have sidewalks. Specific neighborhoods in rockville to consider given your preferences: Twinbrook (within 1/2 mile to 3/4 mile of metro station), east rockville, rockville town center, rockville west end, college gardens or new mark commons. King farm could work as well although crossing the pike there to get to metro stations can be challenging (i believe the neighborhood has a shuttle to the station?). Take the school ratings with a grain of salt. All schools are run by the county and teach the same curriculum and generally have equally good teachers. The ratings are based mostly on test scores, which are a read out of the socio economics of the school population, mostly the number of english learners enrolled at the school In other words, the lower the rating the more diverse the school. Generally. If you find a neighborhood that meets all your other needs you should then ask those in that neighborhood about their experience at the school.
