INSPECTION DATE 7/5/2001
INSPECTOR'S INITIALS TAS
1. A site inspection was made of the Howe Pit as a follow-up to recent information presented
to the Division from the Urban Drainage & Flood Control District (District) regarding
emergency flood control measures that were taken by the District at or near the Howe Pit in
May, 2001. The emergency measures are alleged to be the result of the Bull Seep relocation
within the affected land of the Howe Pit. Present during the site inspection was Sohn
Hickman of Mobile Premix Concrete, Inc.; Jeff Schwarz of Massey, Semenoff, Schwarz, & Bailey,
P.C.; and Bruce Humphries, Carl Mount, and Tom Schreiner of the Division. Photographs were
taken during the inspection. A number of field measurements were recorded and are noted in
Item 4 below.
2. Prior to the field inspection, the Division participated in a June 13, 2001 meeting held
by the District at their offices to discuss the nature and details of the emergency flood
control measures, i.e.: why, what, where, how, & when were the measures implemented. The
meeting was conducted by Mr. Ben Urbonas of the District. Mr. Urbonas discussed the
financial aspects of the emergency measures and also stressed the need for further measures
to ensure the long-term (flood control) stability of the area(s) in question.
Representatives of the various parties were present at the meeting: the District, Division
of Minerals & Geology, Western Mobile Concrete, Inc., Fulton Ditch Company, Applegate Group,
South Adams County Waste & Sanitation District, Adams County Parks, Denver Water Board,
Muller Engineering Co, Commerce City, U.S. Army Corps of Engineers, McIntosh Farm Co.,
Brantner Ditch Company, and adjacent landowners.
3. According to information presented at the June 13, 2001 meeting at the Offices of the
District, there are several locations along the South Platte River where the river had
breached during a May, 2001 storm event into the Bull Seep relocation and the river had
captured the Bull Seep relocation and/or slough. The field inspection verified that the Bu11
Seep slough area in the northwest portion of the permit area had a number of areas of cut or
unstable banks. The cut banks were estimated to be at least 6-8 feet in height. This
inspector estimates there are approximately 249 linear feet of unstable bank that are
definitely within the permit area. There were also cut banks and areas of instability along
the slough that appeared to occur outside the permit boundary. Mr. Hickman indicated that
the operator initiated repair or stabilization work for a portion of the cut banks during the
May, 2001 storm event(s). The repair work consisted of end dumping broken concrete into
unstable area. Mr. Hickman acknowledged the need for further stabilization work and
indicated that the operator is cooperating with the U.S. Army Corps of Engineers to determine
if any 404, Nationwide, or other permits are necessary.
4. Other measurements taken by the Division are as follows:
351' (east edge of South Platte River channel to west edge of excavated pit)
60' (east edge of South Platte River channel to west edge of Bull Seep)
210' linear feet (flood control dike installed by the District)
7' high x 40' top width x 60' bottom width x 210 linear feet (flood control dike)
510' (from south edge of flood control dike to 2nd area of instability/breach?)
5. Given the above measurements, the Division believes that the Bull Seep has been relocated
too close to the South Platte River (see PV 1 below).
6. The Division is currently evaluating the mine plan and maps, information supplied by the
District, and information supplied by the operator to determine compliance on other issues.
