Collins, Colorado 80522 c� Ifl SHEAR ENGINEERING CORPORATION Re: Lot-47,_Hearthfire_P.U.D.,_First_Filing; Ft. Collins, Colorado 1226-Town:Center_Dcive� -- Dear Mr. Barber, This letter serves as final certification for the above referenced address according to the requirements of the Stormwater Utility in the Stormwater Building Permit Notice for this address dated 07/07/00. Certifications include the items noted on the Stormwater Building Permit Notice and are as follows: • Grading certification • Swale certification • Finished floor elevation certification • Property's lot corner elevation certification • Lowest building opening elevation certification All final grading is complete, functions properly and generally meets the intent of the original subdivision grading and drainage design according to the Final Utility Plans for Hearthfire P.U.D., First Filing by Shear Engineering Corporation; Shear Project No: 1552-01-96; Director of Engineering approval date 10/03/97. Attached are the record field shots obtained by Shear Engineering Corporation for the site. Also attached is a copy of that portion of the Grading,. Drainage and Erosion Control Plan from the subdivision utility plans, of which this site is a part. This is for reference only. Shear Engineering Corporation did not do a specific site grading design and plan for this lot. Nor was one provided to Shear Engineering Corporation in preparation of this certification. There is the issue of the Hearthfire P.U.D., First Filing pond overflow structure which is located near the northwest corner of this lot. The issue was discussed in our subdivision certification statement dated April 25, 2000, That correspondence is attached to this lot certification for reference. Page 2 of that correspondence states: The second change is related to the overflow system from the main pond to Richards Lake. The overflow box location was staked in the incorrect. location. The location of the box resulted in the encroachment on Lot 47 of underground pipe. The location of the overflow box was noted fairly immediately after installation. As builts of the system were provided by Mr. Paul Meyer. Mr. Meyer provided the construction staking for Hearthfire P. U.D., First Filing. As-builts were prepared in order to define the actual Lot 47 encroachments. Easements were prepared. There are several pieces of documentation associated with this issue. These are attached for immediate reference. Apparently, the easement was not recorded immediately. The easement has been recently provided to the Countyfor recording. 4836 S. College, Suite 12 Ft.

Collins, Colorado 1226 Town Center Drive) The field shots obtained by us, do not match the subdivision design grades at the rear of Lot 47 as noted, due to the misalignment of the pond outfall storm sewer and the relocation of the pond overflow structure. All other grades, protection elevations, etc. comply with the approved subdivision grading plan. If you have any questions, please call at (970) 226-5334.

Collins Stormwater Utility P.O. Box 580 Ft. Collins, Colorado 80524 Re: Lot 47, Hearthfire PX.D., First Filing; Ft. Collins, Colorado Dear Jay, This letter is written with respect to the storm sewer overflow system and associated easement for Lot 47, Hearthfire P.U.D., First Filing. Our certification' statement dated April 25, 2000 provided discussion concerning the storm sewer outfall adjacent to Lot 47. Generally, that discussion is reiterated here. The overflow box location was staked in the incorrect location. The location of the box resulted in the encroachment on Lot 47 of underground pipe. The location of the overflow box was noted fairly immediately after installation. As builts of the system were provided by Mr. Paul Meyer. Mr. Meyer provided the construction staking for Hearthfire P. U.D., First Filing. As-builts were prepared in order to define the actual Lot 47 encroachments. Easements were prepared. There are several pieces of documentation associated with this issue. These are attached for immediate reference. Apparently, the easement was not recorded immediately. The easement has been recently provided to the County for recording. Our interpretation of the relationship of the easement line to the edge of the easternmost 30 diameter storm sewer overflow pipe is that the easement line is 5' from the edge of the pipe. Of course, we would expect verification of the actual existing pipe location for any proposed encroachments into the easement. Attached is a copy of the print which was provided with the subdivision as-builts and certification. The storm sewer outfall and easement are correctly represented and are based on actual surveyed as -built data and the easement description provided by Paul Meyer. If you have questions concerning the data presented here, please call at (970) 226-5334. Shear Engineering Corporation BWS / mo cc: Steve White Tom Kennedy; Hearthfire, Inc.

Collins Stormwater Utility P.O. Box 580 Ft. Collins, Colorado 80524 Re: Hearthfire P.U.D., First Filing; Ft., Collins, Colorado Dear Jay, This letter serves as final certification for the entire Hearthfire P.U.D., First Filing. Shear Engineering Corporation has been involved during the entire construction process and has made several observations during construction. Field changes that Shear Engineering Corporation has been made aware of, have been documented by Shear Engineering Corporation and will be addressed with this certification. Shear Engineering Corporation has also coordinated all field as -built data requirements. As- builts and elevation shots were provided by Timberline Surveying, Inc. of Littleton, Colorado. All elevations are based on the same datum utilized with the Final Utility Plans for Hearthfire P.U.D., First Filing which were prepared by Shear Engineering Corporation; Shear Project No. 1552-01-96; Date of approval by the Director of Engineering; 10/03/97. Please note that the subdivision datum does not match City of Fort Collins datum. The original survey was provided by Merrick & Company of Denver, Colorado. The datum difference is 3.38. Please refer to attached memo prepared by Shear Engineering Corporation dated 10/12/99. This memo was prepared for Hearthfire P.U.D., Second Filing. However, it specifically addresses the datum issue. The following statement is in the attached memo: • 3.38' must be added to City datum in order to match the current Hearthfire P.U.D. datum. Therefore, 3.38' must be added to all current County Road 13 plan data which was based on City datum. These revisions will be made now. All sitework improvements have been completed. All finished grading has been substantially completed in accordance with the original approved MASTER GRADING PLAN. All drainage facilities have been installed and are functioning appropriately and generally meet the intent of the original drainage design for Hearthfire P.U.D., First Filing in accordance with the original approved MASTER DRAINAGE AND EROSION. CONTROL PLAN. There are two (2) significant field changes which have been made. These changes do not affect the intent of the original, drainage design for Hearthfire P.U.D., First Filing in any way. They simply represent facility location changes which differ than those represented on the approved plans. The first change is related to the Overflow system located near the intersection of Hearthfire Way (The entrance to Hearthfire P.U.D. from Douglas Road) and Hearthfire Drive. Re- alignment of facilities were provided during construction in order to salvage existing trees. The l actual alignment of the finished system is noted on Sheet 18A of 48 which is attached for immediate reference. 4836 S. College, Suite 12 Ft.
