I believe the current number is $183,500. https://www.federalpay.org/gs/locality/washington-dc

Although if that's still too low, check out DHS. They are finding ways of increasing salaries above that limit. (https://www.usajobs.gov/job/709656500)

    Senior Cybersecurity Specialist: $115,400 - $123,700
    Staff Cybersecurity Specialist: $140,400 - $150.200
    Principal Cybersecurity Specialist: $167,400 - $177,800
    Senior Principal Cybersecurity Specialist: $184,700 - $196,000

    In some geographic areas, average starting salaries will be higher because of a local cybersecurity labor market supplement (e.g., metro Washington, D.C. +10%).

If I'm parsing that correctly, $196k+10%=$215k as the cap.
