— Mr. Bill Rucker W-8396 25 September 1992 Paps 14 — Sk� Dismrbanc� Ths nativs soile whieh will be exposed upon completion of strippinp conuin a sipnifieant pereenupe of fins-prained particles. These silty soils ars hiphty:uscsptible to disturbance, paniculariy when wet. Ws recommend th�t tha contraaor mske every effort to minimize disturbence oi stripped surfacec. Thess efforts mey inciude diroctinp surfece w�ter away from open ezcevations and the pl�eement of a coarss a00►e0its surface to protsct proparod subprades. Ii efte work is accomplished in wet ws�Mer, ths placement of a cls�n sand and pravel subbase below paved areas would promote future -- draina0e and improve subprade support. In addition, vehicle traffic over wet subOrades or prepared areat ehould be minimized. Applieation of these measuros will reduce the likelihood of additional ovarexeavation of disturbed soils, and associated cosu for soil ezport and impon will be roduced. CLOSURE It thould be noted that adaquate lonp•term performancc of devslopment on siopinp aitea requires soma vipilancs on the part of the buildin0 conmctor and property ovmer. Enpineered dninaps aystems � should be maintained in adequate workin0 order and problama with enpineered drainape systems or . � netunl draimpe pettems which contribute to ponded or puddled water or saturated soil conditions � � should be corcected promptly. Gradinp cuu and fills, both permanent and temporary, may contribute � �i ; to tlope movement if thay are not propafly desi0ned or constructed. Care chould be taken to note any pround movement durinp the desipn life of the homes. Frequently aubUe pround movements may serve as indieations of instability which could potentially be harmful to developments ff left unchecked. Subilization and repair of slope movements are typicaliy more economically and technically feasible H noted and addressed early. Racommandations presented in this report, if adequately implemented and maintained, shouid allow conauuction of homes which will be serviceabie for the averape dasipn life oi e residential suucture, in our opinion. The conclusions and recommendacions presented in this report are based on the explorations accomplished for this study and on conceptuai devs�opment plans discussed with you. Ths number, location, and depth of the explorationc for Mis study were completed within the site and scope ., conatraints of the project so as to yield ihe infortnation neceasary to formulate our recommendationc. Project planc were in a preliminary stape at the time of this atudy, an no written plans were available. Under the circumstances, it is recommended that we be provided the opportunity for peneral review of the projeet plans and specifications in ordar to confirm that the recommendations and desipn considerations presented in this report hnve been properly interpreted and implemented into the project ' desipn packape.
