City Secretary Contract No. 39970
Dear Mr. Buckley:
Dunaway Associates, L.P. is pleased to submit this Contract Amendment No. 1 for
additional professional civil engineering and land surveying services requested by the
City for Summer Creek Drive and McPherson Boulevard.
1. Summer Creek Drive / Risinger Road Storm Drain Analysis —During the
Conceptual Engineering Phase of the project it was determined that a
significant number of curb inlets would be required at the sag in the proposed
Summer Creek Drive roadway just south of the intersection with W. Risinger
Road to capture offsite stormwater runoff. As a result, and following
subsequent discussions with City staff, the decision was made to evaluate the
possibility of intercepting bypass runoff from Sunwood Circle along W.
Risinger Road east of the intersection with Summer Creek Drive before it
reaches the intersection with Summer Creek Drive. Design of drainage
facilities along Risinger Road is outside the scope of our contract. The
following tasks will be required,
1.1. Hydrologic Analysis -- CONSULTANT will perform a hydrologic analysis of
the watershed contributing storm water to the existing pipe system in W.
Risinger Road, including.
1.1.1. Review the hydrologic data prepared by Welch Engineering Inc.,
(WEI) and verify the sub_watershed delinea#ions far the areas that
contribute storm water runoff to the existing drainage system in W.
Risinger Road.
1.1.2. Compare the hydrologic parameters used by WEI for compliance
with current drainage criteria.

1.2. Hydraulic Analysis — CONSULTANT will perform a hydraulic analysis of
the existing storm drain system in W. Risinger Road, including.
1.2.1. Verify the capacity of the existing curb inlets on Sunwood Circle to
determine the expected surface flow (inlet bypass) that reaches W.
Risinger Road.
1.2.2. Verify street capacities:
1.2.2.1. Verify the capacity of the eastbound lanes of W. Risinger
Road to convey the surface flow (inlet bypass and additional
flow from sub -watershed area) with respect to street capacity
(open lane) requirements in the City's drainage criteria. The
street capacity verification will be used to determine the
location of additional curb inlets (if needed) along the south
curb of the eastbound lanes of W. Risinger Road.
1.2.2.2. Verify the capacity of the westbound lanes of W. Risinger
Road to convey the surface flow with respect to street
capacity (open lane) requirements in the City's drainage
criteria. The street capacity verification will be used to
determine the location of additional curb inlets (if needed)
along the westbound lanes of W. Risigner Road, and whether
such additional inlets should be located on the north or south
curb of the westbound lanes.
1.2.3. Verify storm drain system capacity:
1.2.3.1. Verify the capacity of the existing storm drain line (Main "A" of
WEI plans) in the eastbound lanes of W. Risinger Road to
convey additional storm water intercepted by new inlets
along the south curb of the eastbound lanes.
1.2.3.2. Verify the capacity of the storm drain line (Future Main "C" of
WEI plans) in the northbound lanes of Summer Creek Blvd. to
convey additional storm water intercepted by new inlets
along the south curb of the eastbound lanes of W. Risinger
Road. This option assumes the additional storm water
intercepted by new inlets along the south curb of the
eastbound lanes of W. Risinger Road will be conveyed in a
new pipe parallel to the existing storm drain line (Main "A" of
WEI plans) in the eastbound lanes of W. Risinger Road and
then connected to the storm drain line (Future Main "C" of
WEI plans) in the northbound lanes of Summer Creek Blvd.
1.2.3.3. Verify the capacity of the storm drain line (Main "B" of WEI
plans) in the westbound lanes of W. Risinger Road to convey
additional storm water intercepted by a new inlet in the
westbound lanes of W. Risinger Road.

2. McPherson Boulevard Storm Drain SVstem Exten5lon —During the Conceptual
Engineering Phase of the project it was determined that the original design of
the McPherson Boulevard storm drain system did not include approximately
6.8 acres of contributing area on the north side of the McPherson Boulevard
roadway. Fallowing subsequent discussions with City staff, the decision was
made to extend the McPherson Boulevard storm drain system eastward in
order to intercept the storm water from the additional 6.8 acres.
2.1. Hydrologic Analysis — CONSULTANT will modify the hydrologic
computations to include the 6.8 acres on the north side of the westbound
lanes of McPherson Boulevard and determine the anticipated storm water
runoff from the additional area onto McPherson Boulevard,
2.2. Hydraulic Analysis —CONSULTANT will perform a hydraulic analysis to
determine the location of curb inlets and size of storm drain pipe needed
in the westbound lanes of McPherson Boulevard to intercept storm water
runoff from the 6.8 acres that satisfies the City's storm water criteria.
3. Design Drawings- Deg singer &McPherson Drainage
3.1. CONSULTANT will prepare design drawings showing the layout of the
proposed storm drain system improvements developed for Summer Creek
Drive and McPherson Boulevard outlined in the previous sections.
3.2. CONSULTANT will prepare an opinion of probable construction cost
associated with the additional proposed storm drain system
improvements in Summer Creek Drive and McPherson Boulevard.
3.3. CONSULTANT will perform additional topographic surveys in the location
%J the new work along Risinger Road.
4. Topographic Survey and Easement Documents
4.1. Our current contract includes preparation of nine (9) ROW acquisition and
zero (0} easement documents. After completion of the Conceptual Design
Phase it is now estimated that fourteen (14) slope easements and seven (7)
drainage easement documents will be required.
4.2. Additional topographic survey is required at several locations primarily
along the west side of the proposed Summer Creek Drive ROW at
locations where the existing ground falls away sharply and at creek
crossings. This topo is needed to establish the limit of slope easements
and for the design of drainage structure headwalls and outfall channel
grading.
5. Roundabout at McPherson Intersection
5.1. Additional Design Related to Roundabout
5.1.1. Our current contract does not include sufficient topographic survey
information to design the proposed roundabout. Additional data is

needed south of the existing intersection for design of the new
roadway and drainage.
5.1.2. It is anticipated that the roundabout footprin# will require two (2)
ROW takings on the south side of the intersection not included in our
current contract.
5.1.3. It is anticipated that the design of in -pavement safety lighting will be
required at each of the six (6) roundabout pedestrian crossings.
5.1.4. Landscaping design of the central area of the roundabaut will
include grading, tree/shrub selection and layout, planting details, and
irrigation.
5.1.5. Additional civil design will be required for the following elements:

LOG NAME: 20SUMMER CREEK DRIVE AMEND2DES
REFERENCE NO.: **C-24853
SUBJECT:
Authorize Amendment No. 2 in the Amount of $124,775.00 to City Secretary Contract No. 39970, an
Engineering Services Agreement with Dunaway Associates, L.P., for the Design of Summer Creek Drive
(COUNCIL DISTRICT 6)
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 2 in the
amount of $124,775.00 to City Secretary Contract No. 39970, an Engineering Services Agreement with
Dunaway Associates, L.P., for the design of Summer Creek Drive, thereby increasing the total fee to
$582,078.00.
DISCUSSION:
The 2008 Street Improvement Funds included funds for arterial streets, which included funding for the
engineering and construction of Summer Creek Drive as a four lane divided road from Risinger Road to
McPherson Boulevard.
On March 2, 2010, (M&C C-24111) the City Council authorized the City Manager to execute an
Engineering Agreement with Dunaway Associates, L.P., in the amount of $444,283.00 for the design of
paving and drainage improvements to construct Summer Creek Drive from Risinger Road to McPherson
Boulevard to four lane divided arterial standards.
The agreement was previously revised by Amendment No. 1, approved administratively by the City
Manager in the amount of $13,020.00 (City Secretary No. 39970-A1, February 14, 2011) providing a
revised design for a roundabout at Summer Creek Drive and McPherson Boulevard.
Amendment No. 2 will provide for the design of drainage modifications and additional surveying and
easement exhibits, the need for which was unforeseen at the time the original scope of work was
developed. City staff considers the proposed fee to be fair and reasonable for the scope of services that
will be performed.
Dunaway Associates, L.P. agrees to maintain its initial M/WBE commitment of 25 percent that it made on
the original agreement and extend and maintain that same M/WBE commitment of 25 percent to all prior
amendments up to and inclusive of this Amendment No. 2. Therefore Dunaway Associates, L.P., remains
in compliance with the City's M/WBE Ordinance and attests to its commitment by its signature on the
Acceptance of Previous M/WBE Commitment form executed by an authorized representative of its
company.
This project is located in COUNCIL DISTRICT 6.
