Professional Experience
As a water resources engineer with Sear-Brown, Ms. Haferman's experience
includes design of drainage systems, storm sewers, detention ponds, drop
structures, erosion control, channels, w(~irs, and culverts. Modeling experience
includes but is not limited to the use of SWMM, CUHP, HEC-2, HEC-RAS,
UDSEWER and HY-S. Ms. Haferman's project experience includes:

. US 36/9(/11 Street Sub-District Infrastructure, Broomfield, Colorado:
Completed the off-site storm drainage design for the Flatiron Crossing Mall.
Design included multiple large diameter storm sewers, subdrains, trench
drains, unique pond release structures, aeration system infrastructure for
water quality features, erosion control, open channels, and drop
structures/energy dissipation structures for flows approaching 600 cfs.

. Regional Detention Pond 278 Hydrology Re~evaluation & Final Design,
McClellands & Mail Creek Basin, l?ort Collins, Colorado: Evaluated the
effect of an increased rainfall hyetograph on the hydrology of this hasin.
The report included alternative analysis and recommendations to the
proposed design of a regional detention pond.

. Ridge Road Pedestrian Underpass, Cheyenne, Wyoming: This segment of
the Cheyenne Greenway Trail System included design and construction of
approximately 1400 feet of bike path. Significant design components were
the underpass crossing of Ridge Road, a four-sided box culvert placed 4 feel
below the seasonal groundwater table, and a bridge crossing of Dry Creek
involving protection of existing wetlands and stabilization/erosion control
for existing stream banks.

. The Ponds at Overland Trail, Fort Collins, Colorado: This 280 acre
residential development required design around wetlands and an irrigation
canaL Storm drainage design included special area inlets, storm sewers,
swale5. detention ponds and erosion control measures. HEC~2, SWMM,
and EXTRAN were utilized to model the site and the complex interactIon
of the ponds. irrigation canal and the outfall system.

. Centre:' IhC!1Ue Extension, Fort Co/lins, Colorado: Completed storm
drainage design for this roadway bisecting a 100 year FEMA floodplain.
including three canal crossings and one crossing over Spring Creek.
Included in the design are multiple storm sewers, swales. culverts,
extensive erosion control and the realignment and HEC~2 modeling of the
SherwOt ld Lateral.
