Severna Park and Pasadena in Anne Arundel county both offer you a reasonable commute to Ft, Meade, (I did it for almost 30 years from Pasadena as did many of my co-workers) and excellent public access to tidal waters. That includes the Bay, the Severn, the Patapsco and tributaries of those main rivers.
Both communities offer excellent schools -- In Pasadena, the Bodkin Elementary/Chesapeake Middle and Senior High Schools feeder systems are noteworthy. They draw from excellent income areas and have high parental involvement. I cannot speak to specific schools in Severna Park because my children did not attend them. But by reputation I hear they are good.
