Darke County Engineer Jim Surber...
34th Annual Darke County Engineer’s Annual Report 2011
By James P. Surber P.E., P.S.
Darke County Engineer

In his report, Darke County Engineer notes two bridges that are historic. One of them is the Mill Road bridge off Hwy 36 (near Gettysburg) that is currently under restoration. It was built in 1881 and the current plans are to restore it for pedestrians and bicycles on the Darke County multi-use trail under construction, in phases, from Bradford to Greenville. The department hopes to have work completed by late spring this year.

Noting that the county has “managed to save it over all these years,” Surber added, “the structure is made entirely of wrought iron and should remain in service for decades from now.”

Following is Surber’s 2011 report in its entirety:

This report is prepared yearly for the taxpayer to accurately see all public money received, exactly how that money was spent, and what was accomplished. After nearly thirty-five years, it continues to be a challenge to maintain and improve the County roads and bridges in Darke County, which has more of both than any other county in Ohio.

Besides normal maintenance, last year we contracted hot mix asphalt on 32.26 miles. Our employees sealed cracks on 22.97 miles, surface treated 0.66 miles, and replaced 83 culverts and 22 subsurface tile crossings. Additionally, we designed and constructed two new bridges, rehabilitated three bridges, and performed three large culvert replacements for three Boards of Township Trustees. An additional new bridge was constructed on Otterbein-Ithaca Road as a part of a cooperative road reconstruction project with the Trustees of Harrison and Butler Townships, and the Ohio Public Works Commission.

Dealing with shrinking base revenues and rising costs, we still managed to keep expenses below receipts by $20,829.21. We are now concentrating on pavement preservation and bridge rehabilitation projects, and are fortunate to have been able to replace 401 bridges during the past thirty-four years; eliminating the necessity and costs if we were facing the replacement of ten to twelve bridges each year. Readers are encouraged to contact us with questions or comments.   Phone: 937-547-7375 or email: dce@earthlink.net

2011 ROAD RESURFACING

We contracted resurfacing of 32.26 miles on thirteen different roads which is about 6% of the total Darke County road mileage (519.07). The resurfacing program used 26,326 tons of asphalt (805 tons/mile avg.) and 3970 cubic yards of shoulder aggregate (122 cubic yards/mile avg.).  Walls Brothers Asphalt Company performed the work from May through July.

All resurfacing was funded with 100% County revenue.

The 2011 resurfacing costs averaged $ 55,940 per mile, and in 2010, the cost was $57,958. In 2009, 2008, and 2007, the costs were $53,873, $50,469, and $45,944, respectively. In the last four years, resurfacing costs have risen over 21 per cent.     

County personnel and equipment placed new chip-seal surfaces on Greenville-Celina and Meadow Lane totaling 0.66 miles. The total cost for the two roads was $7,511.25 ($11,380 per mile) of which $4,726.25 was materials and $2,785.00 was labor and equipment.

PAVEMENT MARKINGS

We contracted the application of 479.369 miles of new centerline markings with no-passing zones, and 905.22 lane miles of white edge lines at a total cost of $348,559. Forty three percent ($150,000) of this was paid by a federal grant, leaving the cost to the County of $198,651.59. County employees also repainted all “SCHOOL” and “RR CROSSING” markings. Striping costs averaged $254.76 per mile for yellow markings and $250.14 per lane mile for white edge lines.

CRACKSEALING OF ROADS

County personnel sealed cracks on 22.97 miles of County Roads during the year.  This consumed 63,430 pounds of sealant at an average rate of 2761 pounds per mile. The material cost was $26,577 ($1,157/mile).      
             
ADDITIONAL PAVEMENT

County crews placed a total of 447 tons of asphalt for pavement replacement of culvert trenches, subsurface crossings, and curve widening.

BIKEPATH CONSTRUCTION

We again donated surveying, engineering design, and inspection services to the Darke County Park District for the construction of 1.05 miles (Phase 2) of the county’s bike trail. In return, the district secured grant funding for the cost of materials for a new wooden deck on the historic Mill Road Bridge (project is ongoing) which carries the extended bike trail over Greenville Creek.

TOWNSHIP COOPERATIVE ROAD WORK

In 2011, we provided $16,600 in labor and equipment to twelve Townships and $18,089 in sign upgrade work to eight Townships, all at no charge. County crews replaced six roadway culverts on four Township Roads in four different Townships, three large culverts on three Township Roads in three different Townships, and replaced and installed 314 warning and regulatory signs in eight Townships.

BRIDGE CONSTRUCTION, REHABILITATION & LARGE CULVERT CONSTRUCTION

Three (3) new bridges were constructed, three (3) were rehabilitated, one (1) is under rehabilitation and three (3) large culverts were constructed on local roads in 2011. All design was by Darke County personnel, and the construction of all but one bridge was performed by County personnel and equipment using 100% local funds:

These costs include additions for overhead on labor and materials as mandated by Ohio law and the State Auditor’s policies for force account bridges built after 07/01/03.

BRIDGE REHABILITATION AND REPAIR

The Arcanum-Bears Mill Road Bridge (longest bridge in Darke County) over Greenville Creek received major rehabilitation by the County Bridge Crew. The 250 foot-long, five-span concrete slab bridge, built in 1967, was deteriorated on both deck sides by years of salt and weathering. All loose and defective concrete was removed from the top, bottom, and sides of the deck edges. Permanent steel forms were installed to retain the new concrete and the deck was fitted with waterproofing, new guardrail and new pavement. The repairs will protect and preserve the bridge and avoid replacement which would cost over $1.3 million at today’s prices.
Arcanum-Bears Mill C034-0644 (250’x28’)           $40,087.86     $ 59,235.82      $ 99,323.68

The Hollansburg-Tampico Road Bridge was rehabilitated and widened. The steel superstructure was removed, cleaned, and widened from 24’ to 28’ with the addition of two steel beams. New capped-pile abutments were constructed and the bridge re-installed with a new 3”x6” wood deck, waterproofing and new pavement.
Hollansburg-Tampico C046-0375 (29’x28’)            $30,354.85     $ 23,914.55      $54,269.40

The Friday Road bridge was rehabilitated by a cleaning and refinishing of the steel superstructure, installation of a new 3”x4” wood deck, waterproofing and new pavement. Pavement was furnished by the Twin Township Trustees.
Friday T192-0074   (33’x24’)                                    $ 6,369.68       $10,667.24       $17,036.92

The Mill Road Bridge (oldest bridge in Darke County at 131 years) is now being rehabilitated and will carry the proposed bike trail from Miami County to Greenville. The bridge superstructure has been repaired and fitted with a new 3”x4” timber strip deck and asphalt chip surface. Additionally, the masonry abutments will be re-mortared and new guardrail on the bridge and approaches will be installed when weather permits.

LARGE CULVERTS

Detrick Rd.                   T163-0158    9’x7’x64’           $27,608.56*       $10,705.14   $38,313.70

*On these three Township projects, the materials were provided by the Boards of Trustees of Allen, Mississinawa, and Liberty Townships with the County providing labor and equip.
401 new bridges have been constructed on County and Township Roads since 1977.

ACTUAL FORCE ACCOUNT BRIDGE COSTS

Reported 2011 costs for two new bridges and three rehabilitations: $309,170.60
Actual materials & services: $140,047.42     Actual labor, equip. and fringe: $93,165.55

Expenditures increased $311,094.23 over 2010, due to grant money received and spent on signs and pavement markings, and from funds spent and reimbursed for a bridge and three Township cooperative projects. Our base receipts from gas tax and license combined were down $54,286.67 from 2010, and our interest receipts were down $85,062.53. Rising costs of everything in road and bridge construction and maintenance are more challenging to face with continually decreasing revenue. To stretch the dollars, we operate with a staff of 30% fewer employees than were present in 1977, and they continue to perform all functions except asphalt paving and pavement marking. We also continue to maintain a healthy fund balance as a defense against further economic downturn. Our greatest challenge is to continue to fund an adequate annual resurfacing program to maintain the quality of our pavements.
