MnDOT Cntract N. 1026491 Prject Overview The gal f this prject is t investigate rehabilitatin feasibility and perfrm assciated design services fr six steel arch culverts with stne headwalls, fur f which are lcated in the histric district f Whitewater State Park. The bridge numbers and lcatins f the culverts are: - Bridges 5835 and 5836, TH 74 ver a stream, 2.4 miles suth f the junctin at Cunty State Aid Highway (CSAH) 26 - Bridges 8592, 8593, 8594, and 8595, TH 74 ver a stream, apprximately 5.5 miles nrth f the west junctin at TH 14. The prject is scheduled fr a January 2019 cnstructin letting thrugh State Prject N. 8508-38. Prject Backgrund Bridges 8592, 8593, 8594, and 8595 are lcated with the bundaries f the Whitewater State Park Histric District Bundaries; Bridges 5835 and 5836 are utside the bundaries. Since the histric district is listed n the Natinal Register f Histric Places, the prject is subject t review under Minnesta Statute 138. Subpart 138.665 requires State t seek t avid, minimize r mitigate any adverse effects t the histric district and its cntributing resurces. The General Bridge Management Plan fr histric bridges can be fund at: http://www.dt.state.mn.us/histricbridges/bridge/misc/mgmtplan.pdf Task 1 - Prject Administratin (Surce Cde 1010) 1.1 Cntract Administratin Cntractr will cnduct the administratin f the prject, which will include cmmunicatin with State.

MnDOT Cntract N. 1026491 1.3 Cultural Resurce Crdinatin Cntractr will cllabrate with State s Prject Manager, CRU, and the Prject Histrian wh will be cntracted by CRU. The cllabratin will be dne frm the nset f the cntract t cmpletin f the final deliverables t determine the effrt needed t ensure that the design cmplies with the Secretary f the Interir Standards fr the Treatment f Histric Prperties (SOI Standards) thrugh either the rehabilitatin f the bridges, r the design f replacement bridges that meet the SOI Standards fr new cnstructin within a histric district. 1.4 Stakehlder Crdinatin Cntractr will meet with State s Prject Manager, alng with the apprpriate stakehlders, t discuss strategies and details at key times during the prject s life. The Minnesta Department f Natural Resurces (MnDNR), as the wner f the park, will be a key stakehlder in the prject. All crdinatin with the Minnesta Histric Preservatin Office (MnHPO) will be thrugh CRU, thugh Cntractr may be required t attend up t fur meetings with CRU, the Prject Histrian, and MnHPO. Scheduling meetings and taking meeting minutes are Cntractr s respnsibility. Task 2 - Rehabilitatin Feasibility Studies and Develpment and Evaluatin f Prject Alternatives (Surce Cde 1071) The gal f the rehabilitatin studies is t investigate rehabilitatin feasibility and explre any alternatives that wuld satisfy the Minnesta Histric Sites Act requirements t seek avidance and minimizatin alternatives. The primary need f these studies is t address structural deficiencies s that the traveling public cntinues t have sund bridge crssings at these lcatins. Cntractr s task is t perfrm feasibility studies f bridge rehabilitatin fr each bridge within the histric district that will ultimately lead t the selectin f preferred rehabilitatin alternatives in an apprved envirnmental dcument. State anticipates that the rehabilitatin study phase f the prject will be cnducted frm Nvember 2016 May 2017. 2.1 Data Cllectin and Site Visit Cntractr will review all available infrmatin and data relating t the prject, including rutine inspectin reprts, cnstructin files, histrical surveys, etc. Cntractr will investigate the prject site, identifying any deficiencies and cnstructability issues.

Evaluatin criteria will include purpse and need based criteria, regulatry requirements, and cst based criteria (including life cycle csts). After the develpment f evaluatin criteria, the grup will identify at least ne rehabilitatin alternative that meets the SOI Standards and avids r minimizes an adverse effect t the bridges and the histric district. The alternatives will be develped cllabratively with the Prject Histrian shuld address the bridge cnditin, fcusing n the knwn structural deficiencies and areas f cncern as indicated in the bridge inspectin reprts and ther dcuments, as well as thse nted during the site investigatin perfrmed by Cntractr. The level f detail f the alternatives will be the same fr all alternatives and will be at an apprpriate level f detail fr a prject in the early stages f scping. The range f alternatives being develped will fllw the minimum t high levels f actin as defined in MnDOT s Guidance fr Develping Histric Bridge Rehabilitatin Alternatives dcument. The range f alternatives will be develped t incrprate rehabilitatin measures that avid adverse effects, if pssible. Cntractr will supply all presentatin materials required fr the meeting (i.e. sketches, bards, ther visuals, etc.) and cmmunicatin with stakehlders. Cntractr will cllabrate with State s Prject Manager, State District 6 persnnel, CRU, and the Prject Histrian thrughut the develpment f the alternatives. 2.4 Evaluatin f Alternatives Upn cnclusin f the analysis f the rehabilitatin alternatives, Cntractr and Prject Histrian will facilitate and lead a meeting t present a draft rehabilitatin reprt. Meeting attendees include State s Bridge Office, Prject Histrian, State District 6 persnnel, and CRU. The gal f the meeting is t assess the feasibility f the alternatives and t present a recmmended alternative. If nne f the rehabilitatin alternatives are deemed feasible, State intends t amend this Cntract fr Cntractr t explre ther rehabilitatin alternatives that satisfy the requirements f the Minnesta Histric Sites Act. Cntractr, in cllabratin with the Prject Histrian, will prvide a finalize rehabilitatin reprt after all cmments frm this meeting have been reslved. The draft and the final reprt will use the frmat utlined in the MnDOT Rehabilitatin Study Reprt Dcument. - 3 -
