There st�ould Ue son�e <br /> agreement in place between all users of the driveway prior to work on the site that identifies who is responsible <br /> for any damages caused by this liome constntcdon. <br /> • The proposed storn�sev�rer system raises several concems.The stonn sewer shown to serve the driveway to the <br /> garage���ill likely be problemalic in largerrain events or��t�[ten the itilets clog.It is likely the garage couldflood <br /> as there is no emergency overllow for storm water tl�at caru�ot enter ihe storn�sewer system. The proposed <br /> stonn sewer sl�o��sm east of the hoii�e discharges directly to the lake.This is not acceptlUle and an alternaLive <br /> design sliould Ue incorporated inlo the plan set Lhat.routes water towards the]ake o�rertand 1nd not through a � <br /> pipe to enhance water qualily. <br /> • It is uncleac•if the existing biluminous driue���1y sho�vn nlong the norlli lol•line will remain or��ill Ue ren�oved.lt <br /> 1p�ears thal the access to lhe liome wilt be across l•lie shared drive���ay to tl�e north und if so the exisLing <br /> driveway shou1d be removed to ntinimize hardcover on this site. <br /> • It uppears there.m1y be a sanilary sewer manhole localed nelr ihe norlheasl cocnec ot'the prol�erly.The city . <br /> should verify the tnanhole.location and easetnetil s(atus.The tn�nhole sl�ould be sho���n on the grading plfln and <br /> an easemeni provided over it if lhe manhole is an the subject��roperty and no easement exists. <br /> !'f you have any c�ueslions ple�se c�lf u7e aC(651)604-4863. <br /> � <br /> Yours very iruly, <br /> BON�ST.ROO,R05�NL,ANDERL[K sc ASSOClA1'�S,fNC. <br /> i� � <br /> 1 : <br /> ''f'om Kel(ogg - <br /> Cc: Gre�Geippa,City of Orono <br /> SL.
