WORK ORDER FORM
PURSUANT TO AN AGREEMENT BETWEEN
THE CITY OF FORT COLLINS
AND
Ayres Associates
DATED: May 22, 2015
Work Order Number: KCS-2016-10
Purchase Order Number: Charge #504.5040452306.521210
Project Title: Boxelder Creek and Cooper Slough LOMR
Commencement Date: July 1, 2016
Completion Date: November 30, 2016_
Maximum Fee: (time and reimbursable direct costs): $ 21,907.90
Project Description: This scope of work covers those tasks necessary to complete the Letter of Map Revision
(LOMR) for the three (3) projects being constructed by the Boxelder Basin Regional Stormwater Authority
(BBRSA) and the three (3) projects being constructed by the City of Fort Collins and Town of Timnath. This
funding amount reflects the City of Fort Collin’ share (17%) of the total overall project costs of $128,870.00.
The three BBRSA projects include:
1. East Side Detention Facility (ESDF) – This is a large scale (1700 acre-foot) regional detention facility
proposed between CR 50 and CR 52. The construction of this project is what allows the other projects
to be built.
2. CR 52 – This project is being constructed in coordination with the ESDF project to reduce the
overtopping depth of CR 52 to what it would have been had the originally proposed Edson project been
constructed.
3. Larimer and Weld Canal Crossing Structure – The Boxelder Creek flood flows currently overtop the
Larimer and Weld Canal just north of Vine Drive. The construction of the side spill weir in the canal
bank will insure that the canal bank does not fail during a flood event.
The three City of Fort Collins/Town of Timnath projects include:
1. Opening of I-25 Boxes – With the construction of ESDF it will be possible to open the 2 blocked box
culverts under I-25 and be at or below the existing 100-year flow rates on the west side of I-25 at
Prospect Road.
2. Siphoning of Lake Canal – Immediately downstream of the I-25 boxes there is an existing irrigation
crossing of Boxelder Creek. The crossing is a suspended box culvert with an invert barely above the
invert of Boxelder Creek. Siphoning the Lake Canal crossing will greatly reduce the backwater created
by the current crossing structure.
3. Prospect Road Overflow –This project is channel improvements that convey the storm flows into a new
bridge structure/box culverts under Prospect Road. The flows discharge on the south side of Prospect
Road, onto the effective floodplain.
The construction of these six projects has dramatic impacts on the existing Boxelder Creek floodplain and
portions of the Cooper Slough floodplain. The spills from the Larimer and Weld Canal are reduced with the
construction of the ESDF, reducing the Cooper Slough floodplain downstream of the Larimer and Weld Canal to
the Poudre River.

BOXELDER BASIN REGIONAL STORMWATER AUTHORITY IN
COMBINATION WITH CITY OF FORT COLLINS AND TOWN OF
TIMNATH
Scope of Work for Letter of Map Revision (LOMR)
preparation for ESDF, LWCCS, CR 52, opening of I-25 boxes
and siphoning of Lake Canal for the Boxelder and Cooper
Slough Basins
PROJECT OBJECTIVE: This scope of work covers those tasks necessary to complete the
Letter of Map Revision (LOMR) for the three (3) projects being constructed by the Boxelder
Stormwater Authority and the three (3) projects being constructed by the City of Fort Collins and
Town of Timnath. The three Boxelder Authority projects include:
1. East Side Detention Facility (ESDF) – This is a large scale (1700 acre-foot) regional
detention facility proposed between CR 50 and CR 52. The construction of this project
is what allows the other projects to be built.
2. CR 52 – This project is being constructed in coordination with the ESDF project to
reduce the overtopping depth of CR 52 to what it would have been had the originally
proposed Edson project been constructed.
3. Larimer and Weld Canal Crossing Structure – The Boxelder Creek flood flows currently
overtop the Larimer and Weld Canal just north of Vine Drive. The construction of the
side spill weir in the canal bank will insure that the canal bank does not fail during a flood
event.
The three City of Fort Collins/Town of Timnath projects include:
1. Opening of I-25 Boxes – With the construction of ESDF it will be possible to open the 2
blocked box culverts under I-25 and be at or below the existing 100-year flow rates on
the west side of I-25 at Prospect Road
2. Siphoning of Lake Canal – Immediately downstream of the I-25 boxes there is an
existing irrigation crossing of Boxelder Creek. The crossing is a suspended box culvert
with an invert barely above the invert of Boxelder Creek. Siphoning the Lake Canal
crossing will greatly reduce the backwater created by the current crossing structure
3. Prospect Road Overflow –This project is channel improvements that convey the storm
flows into a new bridge structure/box culverts under Prospect Road. The flows
discharge on the south side of Prospect Road, onto the effective floodplain.
The construction of these six projects have dramatic impacts on the existing Boxelder Creek
floodplain and a portion of the Cooper Slough floodplain. There is a portion of the Cooper
Slough floodplain which is also being affected by the proposed projects. The spills from the
Larimer and Weld canal are reduced with the construction of the ESDF, reducing the Cooper
Slough floodplain downstream of the Larimer and Weld Canal to the Poudre River.
Ayres Associates’ Staff will include:
Project Manager - Chris Pletcher, PE; c (970) 218-5546, w (970) 223-5556
Project Engineer - Jaclyn Michaelsen, PE; c (970) 310-1547, w (970) 223-5556
June 21, 2016
Task 1 – Meetings, Coordination, and Data Collection
1.1 Meetings. This task provides time for Ayres staff to meet with the City of Fort Collins staff
twice during the modeling of the LOMR. In addition Ayres will attend Board meetings and
work sessions as required until the LOMR is submitted to FEMA. This scope assumes 9
months of board meetings.
1.2 As-built Project Survey. This task assumes that detailed as-built survey of the six
projects will be provided to Ayres. The survey will be provided to Ayres in the following
coordinates:
Horizontal: NAD 83 State Plane
Vertical: NAVD 88 coordinates
Any topography required to do the modeling, outside the extents of the projects, will use the
Boxelder LiDAR data that was obtained for the projects. Ayres will obtain and review the as-
built survey information in this task.
1.3 Management and invoicing. This task provides time for the Ayres project manager to
handle invoicing to the Boxelder stormwater authority, City of Fort Collins and Town of
Timnath who will all share in the cost of this work. This task also allows time for the project
manager to track the project budgets for each entity, and progress schedule.
1.4 Provide support, drafting etc. Frequently during the course of design, Project Manager
Myers requests assistance from Ayres with drawings, or figures which he uses to speak with
effected property owners or municipal entities. This task provides time for Ayres to provide
that assistance for concerns related to the project that do not fall within the overall scope of
work, but are necessary to keep the project moving forward. This task assumes 40hrs of
additional assistance.
Task 2 – Hydrologic Analysis for LOMR Submittal
The hydrologic models used for the CLOMR submittal to FEMA for this project will be used as
the baseline for the LOMR submittal. This task assumes that the existing conditions hydrologic
model will not be adjusted for the LOMR submittal.
2.1 Develop As-built Project Hydrologic Model for LOMR Study Area. This task allows
time to update the proposed project EPA SWMM model to include the as-built hydrologic
changes created with ESDF, LWCCS and Opening of I-25 Box Culverts. The other two
projects (siphoning of Lake Canal and CR 52 improvements) will have hydraulic benefits
which will be reflected in the HEC-RAS modeling.
2.2 As-built Modeling of the L&W Canal Spill. The modeling of the side spill weir was
performed in an un-steady HEC-RAS model. This model will be adjusted based on the
as-built survey data of the weir. The spill will be input into the as-built hydrologic EPA
SWMM Model.
June 21, 2016
Task 3 – Hydraulic Analysis for LOMR Submittal (CR 54 South to
Poudre River)
Ayres will use the hydraulic models provided in the CLOMR as the baseline for the LOMR
submittal. All modeling will comply with Appendix C of the FEMA Guidelines and
Specifications (G&S). The approach to each model in the series is described below. This task
assumes that the effective model is the same one that was used in the CLOMR submittal. The
Duplicate Effective modeling was performed in the CLOMR submittal.
3.1 Existing Conditions (EC) Model south of County Road 54. This task assumes that
minor modifications will be required of the existing conditions model that was created
with the CLOMR submittal. Adjustment to the model may be required based on the final
construction of the projects. For example, in the event that cross sections are added
into the as-built conditions model to more accurately represent the projects constructed,
the cross sections will also be added in to the exiting conditions model.
3.2 As-built (AB) Model south of County Road 54. The survey data obtained for the
projects will be input into the proposed project model that was created for the CLOMR.
The as-built model will analysis what was constructed on the site for the six projects.
3.3 Coordination with Anderson Consulting Engineers (ACE). The City of Fort Collins
and Town of Timnath projects were designed by ACE. ACE is also providing
construction management for these projects. Coordination will be required between
Ayres and ACE for these projects.
3.4 Update Existing Conditions (EC) Floodplain Mapping. The existing conditions
floodplain mapping for the limits of the study will be updated. The floodplain mapped for
the CLOMR will be used as the baseline for this task.
3.5 Update As-built Conditions (AB) Floodplain Mapping. The as-built floodplain
mapping for the limits of the study will be updated. The floodplain mapped for the
CLOMR will be used as the baseline for this task.
Task 4 – Update ½ Foot Floodway Model and Mapping (South of CR
54)
4.1 Update Existing Conditions (EC) Floodway Models. The existing conditions floodway
model will be modified with this task. The existing conditions floodway model created in
the CLOMR will be used as the baseline for this task. This task provides time to adjust
the floodway and to minimize the rise to 0.5ft as well as eliminating all negative
surcharges in the model. Frequently when preparing a floodway model it is necessary to
iterate on the solutions many times in order to eliminate all of the negative surcharge
values and also to get the floodway close to the defined parameter of ½ foot.
4.2 Update As-built Conditions (AB) Floodway Models. The as-built conditions floodway
model will be modified with this task. The proposed project floodway model created in
June 21, 2016
the CLOMR will be used as the baseline for this task. This task provides time to adjust
the floodway and to minimize the rise to 0.5ft as well as eliminating all negative
surcharges in the model. Frequently when preparing a floodway model it is necessary to
iterate on the solutions many times in order to eliminate all of the negative surcharge
values and also to get the floodway close to the defined parameter of ½ foot
4.3 Update Existing Conditions (EC) Floodway Mapping. The existing conditions
floodway mapping for the limits of the study will be updated. The floodway mapped for
the CLOMR will be used as the baseline for this task.
4.4 Update As-built Conditions (AB) Floodway Mapping. The as-built floodway mapping
for the limits of the study will be updated. The floodway mapped for the CLOMR will be
used as the baseline for this task.
Task 5 – Prepare LOMR Package
Ayres Associates will compile the hydrologic and hydraulic analysis prepared under Tasks 3 and
4, along with other pertinent data, into a LOMR submittal package by performing the following
work:
5.1 Prepare Narrative and MT-2 Forms.
5.2 Prepare Work Maps. The CLOMR work maps will be updated to include the existing
conditions floodplain and the as-built floodplain. The as-built information will be shown
on the work maps.
5.3 Annotated Firm.
5.4 Data Tables. The following tables will be provided for the LOMR:
Annotated Floodway Data Table
New Floodway Data Tables
City’s BFE Comparison Table for the flowpaths
City’s Map-Model Agreement Table for the flowpaths
5.5 Flood Profiles. The effective flood profiles will be annotated and the as-built profiles will
be created.
5.6 Submit Package to City of Fort Collins and Address Comments. The LOMR
package will be submitted to the City of Fort Collins for review. This task assumes two
rounds of comments from the City of Fort Collins. This task includes time to attend and
support a pre-submittal meeting, one or more meetings with COFC staff to answer
questions and time to address comments and make corrections.
5.7 Submit Package to Larimer County Flood Review Board. Ayres Associates will
submit the LOMR package to the Larimer County Flood Review Board. This task
assumes that the submittal package will be submitted to the County for informational
purposes only.
June 21, 2016
5.8 Submit Package to FEMA and Respond to FEMA Review Comments. Ayres
Associates will submit the LOMR package to FEMA for review and comment. Ayres
Associates will respond to FEMA review comments and provide additional requested
data as necessary. This task assumes one round of comments from FEMA. Because of
the extents of the mapping changes this will actually be submitted as a PMR to FEMA
which will require FEMA to change the maps which is a lengthier process for them.
Exclusions:
This Scope of Work does not include a 500-year floodplain model or
mapping
