This is my daughter, Andra
When she was eight years old.
Andra's all grown up now,
and this is what she does.............
It is the fortunate parent, indeed, who, when bragging
about her children, has to include the curvature of the earth.
A land developer approached Toman Engineering Company
with the desire to develop a 150 Acre property into a PUD (Planned
Unit Development). This agricultural property is located six miles
north of Bismarck, North Dakota, and overlooks the Missouri River
on its western side. This project is unique in that no development
of this type has been attempted in this part of Burleigh County.
Once this project is complete, each lot will have gas, electric,
cable tv, and rural water. The site dimensions are approximately
1,800 feet east-to-west and 4,500 feet north-to-south (six football
fields x fifteen football fields). One hundred and twenty six
total lots were created, 121 of those are residential, the other
5 either being commercial, recreational or non-buildable (green
areas). The bay takes up about a third of the entire acreage.
The biggest challenge of this project was to design the bay and
lots in such a way so no excavated dirt leave the site, and no
extra dirt be brought in from another location. Andra had to make
certain the bay was deep enough for water to the Missouri River.
To avoid stagnation, an underground recirculation line will be
installed on the north end connecting the bay and river. The dirt
excavated from the bay then gets built up onto the building corridor
(an area designated on each lot for a house to be built), and
be at least one foot above the 100-year flood plain elevation
(1638.8 ft).
After much trial-and-error, she accomplished this. The cut into
the bay varied from 13 to 16 feet and the fill into the lots from
6 to 9 feet. The total material excavated exceeded 950,000 cubic
yards. You'd end up with a pile of dirt 445 feet high, which is
equivalent to a 45 story building.
Andra was accurate to the cubic inch.
To picture the magnitude of how much that is, imagine filling
up a football field from endzone to endzone and its entire width
(360' x 160').
The idea was to build a bay with one inlet connected to the Missouri
River on the southwestern end of the property and with as many
lots as possible. By creating four cul-de-sacs, Andra was able
to create a total of 112 (3 commercial/recreational) lots with
river/waterfront access. The photo indicates five cul-de-sacs,
but the south one (on the right side of the photo) will be removed
to make room for the boat slips. This photo was taken from the
side window of a private airplane looking east and slightly south
on November 5, 2004.
Two lots will be built for commercial use, including a possible
restaurant/bar, convenience store and marina (See drawing). The
south side will contain approximately 300 private boat slips available
for rental. Several lots will be set aside for public boat ramps
and parking. The lots north of the bridge at this time will be
considered for condominiums.
Andra was not only charged with the subdivision and grading design,
but all infrastructure including water, sanitary sewer, storm
sewer and asphalt streets with curb and gutter (including the
bridge crossing the inlet). She also had the responsibility for
all construction staking. This entails setting points on the ground
indicating how much dirt needs to be cut or filled at that location.
This includes ground points, street centerline, storm sewer pipe,
etc. (The utility elevation specs have not yet been completed).
After setting the original boundary points for the bay and control
points to be used throughout the project, the construction company
purchased a GPS (Global Positioning Satellite) system. Using this
site as a test for their new equipment, she gave them the next
series of points in an electronic file so they could set the points
themselves. This saved the construction company, the owner and
Toman Engineering time and money since their survey crews didn't
need to spend so much time on the site, and the construction company
didn't have any down time waiting for more stake points and grades.
After surveying the original site for existing surface contours
and features, she submitted the preliminary plat to the City of
Bismarck and Burleigh County Planning Boards for approval in December,
2002. Construction of the bay began in April, 2004. As of December
20, 2004, dirt is still being moved to take out the southern cul-de-sac
and installation of storm sewer pipe emptying into the bay.
