SCOPE OF WORK & LIMITATIONS: 1.Showing the length and direction of boundary lines of the legal description listed above. The scope of our services does not include determining what you own, which is a legal matter. Please check the legal description with your records or consult with competent legal counsel, if necessary, to make sure that it is correct and that any matters of record, such as easements, that you wish to be included on the survey have been shown. 2.Showing the location of observed existing improvements we deem necessary for the survey. 3.Setting survey markers or verifying existing survey markers to establish the corners of the property. 4.This survey has been completed without the benefit of a current title commitment. There may be existing easements or other encumbrances that would be revealed by a current title commitment. Therefore, this survey does not purport to show any easements or encumbrances other than the ones shown hereon. 5.Showing elevations on the site at selected locations to give some indication of the topography of the site. We have also provided a benchmark for your use in determining elevations for construction on this site. The elevations shown relate only to the benchmark provided on this survey. Use that benchmark and check at least one other feature shown on the survey when determining other elevations for use on this site or before beginning construction. 6.While we show a proposed location for this home or addition, we are not as familiar with your proposed plans as you, your architect, or the builder are. Review our proposed location of the improvements and proposed yard grades carefully to verify that they match your plans before construction begins. Also, we are not as familiar with local codes and minimum requirements as the local building and zoning officials in this community are. Be sure to show this survey to said officials, or any other officials that may have jurisdiction over the proposed improvements and obtain their approvals before beginning construction or planning improvements to the property. 7.Note that all building dimensions and building tie dimensions to the property lines, are taken from the siding and or stucco of the building. 8.While we show the building setback lines per the City of Orono web site, we suggest you show this survey to the appropriate city officials to be sure that the setback lines are shown correctly.

Inlet protection must be installed in a manner that will not impound water for extended periods of time or in a manner that presents a hazard to vehicular or pedestrian traffic. DURING CONSTRUCTION: ·When dirt stockpiles have been created, a double row of silt fence shall be placed to prevent escape of sediment laden runoff and if the piles or other disturbed areas are to remain in place for more than 14 days, they shall be seeded with Minnesota Department of Transportation Seed Mixture 22-111 at 100 lb/acre followed by covering with spray mulch. ·A dumpster shall be placed on the site for prompt disposal of construction debris.
