Re: Fire Hydrants Near the Ambassador Bridge and Plazas

Dear Dan:

I am a licensed Professional Engineer in both Michigan and Ontario and as requested, I have reviewed the NFPA 502 code as it relates to the spacing and location of •re hydrants along bridges and elevated roadways. NFPA 502 Section A.6.6.3 states that where a municipal or privately owned waterworks system is available, consideration should be given to providing fire hydrants along bridges and elevated roadways at a spacing not to exceed 305m (1000 ft). Based on topographic data and a physical field review, we have prepared a map showing the locations of the existing fire hydrants and bridge deck fire department connections adjacent to the bridge extending from the Detroit River banks to the customs plazas in both countries. As you can see from the map, sufficient number and spacing of fire hydrants and fire department connections are provided to meet NFPA where there are waterworks available.

If you have any questions or need anything more, please contact me.
