l ( Geotec6aicai Eng�i��eering Report • ' Lo�vell Shon Plac June 2, 1999 NCA File No. 259499 Page 12 crawl space. Sitr grading should be designed such thet all crawl space dreins have a minimum of 1 foot of fnll. Roof dowvspout drainpipes should not be connected fi the footing dnin sysoem. All roof downspoirt drains shonld be separately righNined to discharge. 71�e footing drsm system shwld have a minimvm oi 12 inches of vertical fall before it is connected to the roof drein system. We recommend that sufficiem cleanou� be installed at strategic locetions to allow for periodic m�lntenance of tbie foocing de�in end downspout drait�pipe system. A washed rock or pea gravel filled collector drain should be constivcttd arour.d the saaitary sewv vnult where the wL�er seepage was observed at the gtound surfece. ihis drain should be routed to the wetlwd arw. Other construction or pamenmt collector drains msy be needed wbete sitrfece watet is encouirtered. If the collector drain is locattd within the roedway, we recommend the use of Slter fnbric around the roek to teduce inflow of wil into the drain. USE OF THIS REPORT We have propazed this repart for The Tredway Corporation and their egents, for use in plannina end design of this project. The daia and report should be provided to pro�pecave contraewrs for their bidding and esdmating purposes, but ow report, conclusions and inttrpretatioos should not be construed as a wa�ranry of subsurface conditions. Final developmeM plaus were not available at the time this teport was proparcd. We recommend tfwt we be retained to roview the finel plans md provide additional desi� inpu; es necessary, prior to construction. Speeific areas that should be reviawed include ret4iniug wells, rockeries,and the detendon pond. The scope of our work does not include se[vices relaud to conshuction safety precautions, end our recommendations are uot intended to dircct the contractors' methods, techniques, aequences, or procedums, except as specifically described in our report for consideradon in design. Thero are possible vatiations in subsurfacz r.onditions. We recommend that project plenning include contingenclos in budget and schedule,should areas be found with condidons that very from tho�e described in this report. We recommend that wc E *etained to provide monitoring services for geotechnicel aspecYs of the work i during coasWction. As part of ow services,we would verify site conditions fonad during wnstruction, and compare them with the data obteined in our explorttdona and evaluate soil bearing during constntetion Jn the event that condiHons vary, we would provide mommendations as appropriate.
