City of Arden Hills <br />Proposal QTB210666 <br />February 21, 2025 <br />Page 3 <br /> <br />Figure 1 below shows an illustration of our proposed boring locations. <br /> <br />Figure 1. Proposed Boring Locations <br /> <br />Figure annotated in and extracted from Google Earth™. <br /> <br /> <br />If the intended boring depths do not extend through unsuitable material, we will extend the borings at <br />least 5 feet into suitable material at greater depths. The additional information will help evaluate such <br />issues as excavation depth. If we identify a need for deeper (or additional) borings, we will contact you <br />prior to increasing our total estimated drilled footage and submit a Change Order summarizing the <br />anticipated additional effort and the associated cost, for your review and authorization. <br /> <br />If the borings encounter groundwater during or immediately after drilling of each boring, we will record <br />the observed depth on the boring logs. We will not leave any of the boreholes open for an extended <br />period of time. <br /> <br />MDH Notification and Sealing Record <br />Since our planned exploration will be less than 15 feet in depth, the Minnesota Statutes will not require <br />that we complete any notifications or sealing records. If we extend any of the borings to a depth of 15 feet <br />or greater, the Statutes requires that we seal the boreholes and complete a Sealing Record. If 25 feet or <br />greater, the Statutes also require us to complete a Sealing Notification Form. If the Record or Form are <br />required, we will contact you to discuss the additional fees and sealing requirements.
