The subdrain line should be tightlined to <br />discharge into a permanent storm drain. <br />Under no circumstances should roof downspout drain lines be <br />connected to the garage wall subdrain system. All roof downspouts <br />must be separately tightlined to discharge into a storm drain <br />system. We recommend that sufficient cleanouts be installed at <br />strategic locations to allow for periodic maintenance of the garage <br />wall subdrains and the downspout tightline systems. <br />LIMITATIONB <br />Oanaral <br />�.� i.� Our recommendations and conclusions are based on the site materials <br />� � i' observed, selective laboratory testing and enqineering analyses, <br />and our experience and engineering judqement.
