Architecture Technologist Salaries in Newark, NJ

Im an Architect project manager with 10 years of experience in a specialized market. In January , I got a 5% raise as part of the yearly evaluations. In February, my direct supervisor left (manager with 30 years of specialized experience) and Ive taken over his projects. I was going to wait until the 6 month mark to ask for a raise but given the added workload Im inclined to do it now. My goal is to ask for a 10%-15% raise. I have gotten significant raises in the past. Should I ask for it now?
