Mr.Bilt Way Ju[y 25, 1996 PROJECT DESCRIPTION We wecti provided with a preliminary grading plan dated Febivary l996, prepared for development of the �Iarbeck site. This plan shows construction of an interpmtive shelter, restrooms, geenhouses, nucsery piant plots,an�t parking and driveway facilities. A small amphitheater and naturc trails aze also included in the development Thocgh floor elevations of thc swcturcs arc not shown, it appears they w•ill be placed neaz existing site grades. We expect the structures �,vill be nlatively light,with foundation loads ef about one kip or less per lineal foot along load-bearing walls. A recently provided sketch, dated June 7, 1996, shows slightly rcvised locatians of the swctures. The sketch shows reorientation of the restrooms and relocation of the interpmtive shelter, grcenhouses, and nursery plant plots to approximately 20 feet south of the locations shown on the preliminary �ading plan. Review of the grading plan indicates two pond areu will be constructed north of the proposed visitor facilities. Pond bottom elevations will be approximately 522 feet and 524 feet at the eastern and westem pond areas, respectively. Conswction oF these ponds will require excavation of up to l4 feet below existing site gndes. The grading plan indicates pond excavation and landscaped fill slopes will be graded to inclinations as steep as 13:1 (Horizontal:VeRical). The rcco�nmenda;�ons contained in this rcpoR arc based on the above design features. We should review final design drawings to verify that our recommendadons have been properly interprcted and to supplement them, if required. 1n addition, we should provide construction observation and tesdng servica as needed during construction. SITE CONDITiONS We conducted our field investigation for this phase of our work on July 3, 1996. The following sections summarize the results of our exploration. Surface The site lies within an undeveloped arca bounded to the south by Narbeck Swamp and to the west by Seaway Boulevard. The site is accessed from Seaway BoUlevard by a gravel road leading eatt into the - site and tuming south toward Narbeck Swamp. Most of the site is tlat. A,broad,two to four-foot high knoll lies at the site's eastem margin adjaant to the edge of the swamp. A steep, approxim�tely six-foot high (maximum) embankment lies along the westem margin of the site adjacent to the edge of Seaway Boulevard. The site's southem margin slopes ver�gently to the south toward Narbeck Swamp. Project No.T-2736-1 Page No.2
