New Parking?

Aaron, I don't see why you wouldn't be able to achieve both credits. As long as you can prove the number of existing parking spaces prior to construction and show that the number has not changed post construction, you should achieve SSc4.4. But your LEED boundary should include the parking area. I would write a comprehensive narrative explaining that it is to repaved and repainted only and provide site drawing(s) for your documentation. You should be able to designated the number of preferred spaces for SSc4.3 and achieve that credit as well. Remember that no matter how you draw your LEED boundary, it will affect your stormwater and other site credits you may be attempting.

Aaron, I would be mindful of how you document your credits, including the site plan that you present for the general narrative. Even though the parking lot is outside the property line you state that it's within the same scope of work (and budget?) as the rest of your project. My sense is that you would have to include your parking lot in the LEED boundary. You didn't mention if this was v2.2 or a 2009 project. For 2009 they clearly list Minimum Program Requirements regarding site boundary - http://www.usgbc.org/ShowFile.aspx?DocumentID=6715. I'm pretty sure these boundary requirements always existed but they made them official by documenting them for this version. See numbers #1 and #5 under section 3. Follow this an you can't go wrong.
