Narrative:

[We were] assigned the LAZIR1 RNAV departure off runway 01 in dca. After takeoff; pilot flying (PF) called for FMS navigation at 400 ft. He continued the course guidance; however; once reaching the river; it appeared as if continuing on the FMS guidance would take us into P56. I told the first officer (PF) to turn immediately to the left and follow the river. I informed ATC we were deviating from the RNAV departure so as to remain clear of P56. He acknowledged and instructed us to intercept the dca R328 and report established. We complied. Shortly thereafter; I commented to ATC that it appeared to us that if we continued on the LAZIR1 it would've taken us into P56. He said we weren't the first to complain of that and suggested we inform the company of the event. Another company aircraft followed us out of dca and confirmed everything we experienced with the departure. The other event necessitating an as soon as possible was a speed limit exceedance on the departure. While setting the PF up to intercept the dca R328 as instructed by ATC; he allowed the speed to increase to approximately 270 KTS at approximately 5;000 ft. I called out the deviation and he immediately corrected the situation.this departure (LAZIR1 RNAV) should be immediately suspended until it can be further reviewed and ensured that P56 will be avoided. It was a real eye-opener to us and according to ATC there have been many complaints from pilots that it takes aircraft way too close (or slightly into) P56. The speed limit violation occurred because of the distraction caused by the deviation from the RNAV departure.
