For the purpose of the transfer contemplated by this section, the affected individuals shall be allowed to restore withdrawn contributions to the city employees' retirement system and reinstate their membership service records.
Any employee so transferring shall have all the rights, benefits and privileges that he or she would have been entitled to had he or she been a member of the city's police relief and pension fund system from the beginning of his or her employment with the city.
No person so transferring shall thereafter be entitled to any other public pension, except that provided by chapter 41.26 RCW or social security, which is based upon service with the city.
