2002 – Structure 4 emergency spillway
2004 to 2009 – various maintenance
Ongoing mowing and debris removal

Removed trees
Removed sediment bars
Placed riprap in various area for
erosion control
Construction cost: $390,000

Before
After
Structure No. 4 Riser
Remove riser
Install trash rack
Provide access around base of dam
Construction Cost: $240,000

Structure No. 4 Emergency Spillway
Constructed spillway with roller
compacted concrete (RCC)
Construction Cost: $880,000

2003 – 2009 Maintenance
2006 – Channel maintenance between
New Lothrop to North Byron Roads
(Shiawassee and Genesee)
– Construction cost - $50,000
2004 & 2009 – Dike repairs and rip rap
– Construction cost - $70,000
2003 to 2010 – Ongoing debris removal
and mowing and minor maintenance items
– Approx. $6,000 annually

2009 Inspection
Severe erosion and wash outs
– Verne Road to upstream of Burt Road
– Structure No. 4

Inspection Conclusion
Dikes near Burt Road to Verne Road
are prone to fail without corrective
measures
Significant erosion
Horizontal cracking
Near vertical banks
25% have experience severe erosion
50% in near “sloughing” condition

Severe Erosion to Top of Dike between
Birch Run and Burt Road

Erosion Between Birch Run and Burt Road

Erosion – Loss of Dike Width – Between
Fergus and Birch Run Road

Cracks in Soil of Dike – Near Burt Road

Dike in Condition Poor Condition
Erosion has significantly increased
since 2003 inspection
Dikes are at risk of failure
Highly recommend to implement
improvements

High Risk of Dike Failure
Failure during storm results in:
– Emergency conditions
– Significant flooding
– Damage to farmland
– Damage to houses likely
– Damage to roads and culverts likely
– Environmental problems likely
– Risk of injury or death
– Emergency services

Minimum Recommended
Improvements to Dike
Reshape / reconstruct dikes slopes to
2 horizontal on 1 vertical
Construct two stage low-flow channel
with 10-foot shelf
Expand dike top width to minimum
of 16 feet
Add riprap at bends to control
erosion

Typical Cross Section

Projected Cost
$2.5 million
– Reconstruction of Dike from Verne and
upstream of Burt Road
– Erosion control measures at Structure 4
– Surveying and Engineering
– Smaller maintenance in other areas
– Future maintenance needs
