City of Lake Elmo <br />CSAH 14 Watermain Improvements, City Project No. 25X.140463 <br />Revision 1.0 <br />Proposal 10002208_001 <br />November 13, 2025 <br />Braun Intertec Page 3 <br /> <br />Figure 1. Proposed Boring Locations <br />Figure provided by the City of Lake Elmo <br /> <br /> <br />If the intended boring depths do not extend through unsuitable material, we will extend the borings at least <br />5 feet into suitable material at greater depths. If we identify a need for deeper (or additional) borings, we will <br />contact you prior to increasing our total estimated drilled footage and submit a Change Order summarizing <br />the anticipated additional effort and the associated cost, for your review and authorization. <br /> <br />Groundwater Measurements <br />If the borings encounter groundwater during or immediately after drilling of each boring, we will record the <br />observed depth on the boring logs. <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 that <br />we complete any notifications or sealing records. If we extend any of the borings to a depth of 15 feet or <br />greater, the Statutes requires that we seal the boreholes and complete a Sealing Record. If 25 feet or greater, <br />the Statutes also require us to complete a Sealing Notification Form. If the Record or Form are required, we <br />will contact you to discuss the additional fees and sealing requirements. <br /> <br />
