NC-2009 WEp1:Water Use Reduction—20% Reduction

Occupants / users of public park

Our project includes the creation of a park, and construction of a pavilion with restrooms for park users. The challenge - how do we calculate the number of FTEs using these restrooms? Anyone has any ideas/experience with this? thanks!

I hate to follow a question with a question, but my first thought is how many FTEs are you assuming for your project? Based on MPR 5, (http://www.usgbc.org/node/1731546?return=/credits/new-construction/v2009/minimum-program-requirements) the project must have a minimum of 1 FTE calculated as an annual average. Are there staff at the park on a regular basis?

If the park is open to the general public, in addition the other project FTE's, then standard practice is to write a narrative explaining what you expect the usage to be...it will just be a guess, but as long as your numbers are well reasoned, it should be accepted. You could take into consideration factors such as population density of the surrounding community, proximity of schools, is the park likely to be in the travel path of people going shopping, are there factors that would draw people to the park in it's own right etc. consideration.

I would increase your "transient" number, by what ever you estimate the number of park visitors to be, assuming of course the park pavilion fixture flow rates are the same as the rest of the project.

Thanks, Charles. We did find some studies of park usage and could be applied to our project.

Wanted to give an update on how we determined the number of park users. We followed Charles' advice to use population density, and managed to find a report on percentage of park users relative to the distance of such residents from the parks themselves. As to Gerren's question, the pavilion includes a retail component, so there are FTEs associated with the building. Thanks to all for the help!
