Re: Pinnacle Townhomes P.D.P.; Fort Collins, Colorado
Drainage Certification #1 (interim conditions)
Dear Jay,
In an effort to allow continuation of townhome unit construction with the release of additional
building permits according to the requirements of the development agreement, a drainage
certification is required. The entire Pinnacle Townhomes PD.P. site is not 100% complete as of
the date of this certification. Therefore, this certification is considered interim in nature.
Completion of the primary drainage improvements at the south portion of the project was
directed in order to complete this interim drainage certification. Those improvements include
valley pans, culverts, water quality pond and associated drainage improvement appurtenances.
As -built field elevation shots were also directed. These were provided by Northern Engineering
Services on Tuesday, June 03, 2003.
All interim drainage improvements field shots were made to confirm that the curb, gutter, valley
pans, culvert inverts and related drainage improvements constructed in the southern portion of
this site function properly and are completed in substantial compliance with the direction, details
and specifications according to the Final Utility Plans for Pinnacle Townhomes P.D.P. by Shear
Engineering Corporation; Project No: 1555-02-00; City of Fort Collins Director of Engineering
approval date 09/04/02.
Shear Engineering Corporation has reviewed the record field shots provided by Northern
Engineering Services at the Pinnacle Townhomes P.D.P. project site. All field shots are record of
the interim drainage improvement conditions for the southern portion of Pinnacle Townhomes
P.D.P. as of the date of this interim drainage certification.
Specific plan sheets reviewed for compliance include:
Sheet 17 — Overall Master Grading Plan
Sheet 18 — Master Grading Plan
Sheet 19 — Master Grading Plan
Sheet 20 — Water Quality Pond Detail
Sheet 21 — Overall Master Drainage and Erosion Control Plan
Sheet 22 — Master Drainage and Erosion Control Plan
Sheet 23 — Master Drainage and Erosion Control Plan
Sheet 25 — Detail Sheet — Street and Concrete
Sheet 26 — Detail Sheet — Drainage and Erosion Control

Re: Pinnacle Townhomes P.D.P.; Fort Collins, Colorado
Drainage Certification #1 (interim conditions)
Sheets 18 and 19 are attached for your immediate reference.
All curb, gutter and related drainage improvements constructed in the southern portion of the
Pinnacle Townhomes P.D.P. project site function properly and have been completed in
substantial compliance with the direction, details and specifications according to the Final Utility
Plans for Pinnacle Townhomes P.D.P. Northern Engineering's record field shots are indicated on
the attached sheets 18 and 19 (Master Grading Plan).,
Water quality pond as -built elevations were also provided by Northern Engineering Services.
Our initial analysis of the data provided indicated that further grading in the bottom of the pond
was required for full compliance with the approved plans. Additional effort was directed. Upon
completion of the additional grading effort, a representative of Shear Engineering Corporation
made further observations on Thursday, June 12, 2003. The water quality pond was now
completed in substantial compliance with the direction, details and specifications according to
the Final Utility Plans for Pinnacle Townhomes P.D.P. Hydroseeding of the water quality pond
was authorized by Shear Engineering Corporation.
A final drainage certification will be required. This will be provided upon completion of the
remaining Pinnacle Townhome P.D.P. improvements. Those improvements 'primarily consist of
the completion of street curb, gutter and walk and parking lot curb gutter and walk. All specific
lot and unit certifications will be provided separately upon completion of each individual
structure according to the requirements of the development agreement.
If you have any questions concerning our observations, please call (970) 226-5334.
Sincerely,
M. Adam Denton
