But the boardwalk, like the on-land portions of the Schuylkill River Trail, is designed for that. Much of the structure is concrete, so rust is not a major concern, and the broom finish on the deck surface will keep the boardwalk and ramp from becoming too slippery. The lighting that SRDC hopes to install will be both solar powered and out of the flood plain. (SRDC is working to secure additional funding for lighting, which was initially taken out of the contract for financial reasons.)
