Narrative:

After joining the 31L localizer and cleared for the visual to 31L with aircraft configured flaps 20 and speed 180 KIAS; noted aircraft slightly right of our course on TCAS. Obtained visual on aircraft and at approximately 1;800 ft; an RA was issued. After starting to comply; 'clear of conflict' was issued and visual approach was continued to successful landing. This is the second RA I have had into bfi in less than a month. Very heavy general aviation traffic in the area and ATC needs to provide better separation.
