Northern Engineering visited the site on November 25, 2008, to record spot elevations of building corners, drive isles, and the parking lots. Northern Engineering again visited the site on January 27, 2009, to record spot elevations of the lot corners and the building finish floor. Stantec Consulting Ltd. reviewed the topographic information provided by Northern Engineering. In general, the recorded spot elevations were within acceptable construction tolerances. However, several recorded spot elevations were outside of acceptable construction tolerances. The most significant of these areas was east of the trash enclosure along the south wall of the truck docks. Elevations differed as much as 0.38' from the approved utility plans. The contractor indicated that the grading was altered due to modifications to the trash enclosure and input from the client regarding operation of the truck docks. The basic drainage concept as depicted in the approved utility plans was not modified and no adverse effect is expected. Stantec Consulting Ltd. visited the site on Monday 26, 2009, to inspect grading, drainage patterns and landscaping. Landscaping around the building does not appear to interfere with the proposed drainage patterns. No low spots were observed in the landscaped areas, drive isles, or parking lots. Additionally, no cross lot drainage to or from adjacent lots outside of drainage easements is expected. This certification is signed and stamped by a professional engineer registered in the State of Colorado. By signing this certification the engineer attests that to the best of his (her) knowledge the surveyed grading as shown in the enclosed certification is in compliance with the approved grading plan for this lot and subdivision as shown on the approved utility plans.
