CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On -Site Systems Approval Guidelines, indicates that the on-site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm Arcterra Consulting Phone (907)-696-6111 Engineer's Printed Name Kenneth Duffus Date A ; Engineer's Comments: This investigation was completed in compliance with ADEC and MOA regulations. ♦%Rwww r The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The �L OF flow and absorption rates may change due to subsurface conditions that may not be observed from the �.0 surface, changes inland use, local soil characteristics, groundwater levels that may fluctuate during the year o �7 and the water usage of the family being served by the system. The operational life of all well and septic 4 systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, ArcTerra can not give any estimate of how long a system will S t function satisfactory for current or future occupants or can ArcTerra guarantee that no unseen encroachments, deficiencies or discrepancies exist f !{EINE F 5 Iry I♦, rE tS5 �`1 i A. 0 L ani =kms COSA Checklist—June 2022 o DUBEN AVENUE o Cl) 9 C Cn z C 9 CD < 5 CD m Oo � W S� 0) co N 89055'00" E 82.57' ----------- El/2 ------E1/2 N1/2 W1/2 SHED NE1/4 NW1/4 WELL SE1/4 NE1/4 13,618 sq. ft. 33.4' U' 0. 0' GRAVEL DRIVEWAY UTILITY POLE L - a 0 O O 00 C W Z v C C m < CY) m 0 2 -STORY N FRAME N 1111111110 110 I 33.4' 38.3' (S; SEWER CLEANOUT N Oo y Y SHED w REBxAR x �T,�E, UTILITY PEDESTALS FENCE S 89054'55" W 82.56' LOT 2A EASEMENTS OF RECORD, OTHER THAN THOSE SHOWN ON THE RECORDED SUBDIVISION PLATARE NOT SHOWN HEREON.
