Purpose of Report The purpose of this report is to document the engineering assessment phase of project development, including all coordination that has been completed in preparation for this bridge project. This document outlines the proposal and is intended to serve as a guide for subsequent survey, design, environmental, right of way and other project activities leading to construction. The preferred alternative identified in this document is considered predecisional, pending the outcome of environmental studies.

Project Location This project is located on I94, from a point 0.1 mile west of I80/90 (Toll Road) to a point 0.43 mile east of SR49 in Porter County. The project is in the Indiana Department of Transportation’s LaPorte District, Gary Sub‐District. This location is in a rural planning organization region, the Northern Indiana Regional Planning Commission (NIRPC).

Project Need and Purpose The need of this project is based on the existing condition of the storm water management system for the I94 corridor. Based on existing condition data, all of the small culverts are in less than fair condition, with all pipes showing rust and corrosion, mainly a result of the use of chlorides during winter operations. The median drainage is managed by inlets along the concrete median barrier, connected with small section of corrugated metal pipe, which are all in poor condition. The cross culverts under I94 are all rated in poor condition and there have been three sink holes reported in this section of I94 due to the poor condition of pipes under the mainline pavement and median. The purpose of this project is to rehabilitate the storm water management system for the I94 corridor, improving the overall condition of pipe culverts and inlets to good or better.

Existing Facilities The existing roadway facility is classified as an Interstate and is part of the 3R roadway network and is part of the US National Highway System (NHS). The roadway is on the National Truck Network. The posted speed limit at the project location is 70 mph. Roadway The existing roadway is 36’ per bound through the project limits. The existing roadway consists of 12‐foot travel lanes and 17’ median / 10’ outside paved and useable shoulders. The existing shoulder

Drainage Existing drainage through the project is primarily through sheet flow away from the road into ditch lines on the outside of the pavement, or sheet flow to the interstate median. The storm water management system was established to convey runoff from the median to the outside side ditch lines, or to propagate flow under I94 to larger ditch lines or streams. All of the cross‐pipe small culverts and large culverts were constructed in 1969 and were not replaced or rehabilitated in 1992 when the pavement was replaced, and the median was enclosed. The current median drainage appurtenances (H5 and X5 inlets with outlet pipes) were constructed in 1992 and have not been rehabilitated since that project. This section of I94 had the drainage appurtenances inspected in 2017/2018 with condition ratings no better than fair (5). The majority of the pipe culverts were rated as poor (3), requiring rehabilitation. There is a total of 182 storm water management structures of some type (pipe culvert, H5 inlet or X5 inlet) within the project limits. Of these structures, there are 27 pipe culverts that are considered cross pipes (connect one outside side ditch to the other outside side ditch, rough length ±210’). The median drainage consists of 133 H5 inlets (66 pairs where the H5 inlets on either side of the concrete median barrier are connected in series), and 16 X5 inlets. There are 31 sets of H5 inlet pairs that have outlet pipes that carry runoff under the mainline pavement and shoulders to drain into an outside side ditch line. There are no storm sewer pipes directly under the concrete median barrier between the POB and mile post 19 within the project limits. Eighteen H5 inlet pairs are connected to each other or a cross pipe culvert with longitudinal storm sewer pipe (mostly CMP) running directly under the concrete median barrier between mile post 19 and the POE. Railroads I94 crosses CSX tracks at RP 16+65. No insurance is anticipated for this project as all work should be at least 50’ from the tracks. The crossing is not at grade.

Crash Data & Analysis Crash data was not reviewed as part of this assessment as crash analysis does not impact the purpose or support the need of the project.

Alternatives and Recommendations Alternate A: Do Nothing This alternate would allow the existing drainage appurtenances to remain in place with no improvements. This alternative will result in continued deterioration of the culverts, and significantly increase the risk of significant failure of a pipe culvert under the I94 mainline pavement, thus impacting public safety of an interstate corridor. This alternative does not meet the need nor achieve the purpose of the project and will not be considered further. Alternate B: Rehabilitate the existing storm water management system This alternative meets the need and purpose of the project and is the preferred alternative. Details of Preferred Alternate Rehabilitation of the existing drainage system though the length of the project involved addressing the following items:

1. Existing H5 inlet pairs with pipes under the concrete median barrier; pipe is deteriorating and cannot be adequately maintained due to the H5 inlet structure dimension.

2. Pipe culverts crossing under I94 in poor condition 3. Existing storm sewer pipes running under the median shoulder of I94 that are in poor condition 4. Connection of longitudinal storm sewer pipes to cross pipe culverts and the condition of said

connection. H5 Inlet pairs: All H5 inlet pairs will be removed and replaced. This is required to eliminate existing poor condition pipes under the concrete median barrier. These paired inlets will be replaced with a Florida DOT (FDOT) standard median inlet (see appendix for standard plan) that eliminates the pipe under the concrete median barrier. Cross Pipe Culverts: All cross‐pipe culverts shall be lined with CIPP. Cross pipes originating from the median (i.e. from an H5 inlet pair) shall be lined with CIPP after replacement of the upstream H5 inlet pair. Note no pipe lining shall be done prior to replacement of existing longitudinal storm sewer pipe connections. Existing Storm Sewer Pipes: Buried pipes running longitudinally within the median that are not directly under the concrete median barrier shall be removed and replaced in kind. Buried pipes running longitudinally with the direction of traffic under concrete median barrier are to be abandoned in place (see USP within this document). This system shall be replaced with new longitudinal storm sewer pipes running under the median shoulder using the same pipe size as provided under the concrete median barrier. Due to the nature of the corridor, no CMP is allowed for Type 1 pipe material in this corridor. Existing Pipe Connections: There are two types of longitudinal pipe connections existing within the project limits.

a. Inlet to inlet connection. This shall be perpetuated due to replacement of the upstream and downstream inlets as well as replacement of the longitudinal storm sewer pipe.


Des #: 1592882 Page 4 of 6

b. Storm sewer pipe to cross culvert connection: These connections occur primarily with cross pipe culverts with a top size of 36” diameter. These connections shall be replaced with a Manhole, Type J or Type K to facilitate a positive, engineered connection that allows future maintenance access to the storm sewer system.

All pipe trenches shall utilize Flowable Backfill, Removable to facilitate accelerated construction techniques. Designer shall video inspect existing pipes to determine the extent of any section loss for each pipe. Note that significant clean‐out of existing pipes may be required to facilitate accurate video inspection of the pipes within the project limits. The current recommendation may be revised in design once the actual section loss for each pipe is determined. Replacement of pipes crossing under I94 to side ditches is a possibility, and if required, will entail a scope change and review by District staff. Pavement design and a geotechnical investigation will be needed for this project to ensure that the PCCP Patching required for the median shoulder is appropriate. This drainage system rehabilitation is proposed to take place in construction year 2024

Cost Estimate The cost of the preferred alternative is as follows:

Estimated Total Project Costs Amount Comments Right of Way Purchase Right of Way Services Preliminary Engineering $250,000.00 Railroad PE $50,000.00 Railroad CN 0.00 No RR impacts anticipated Utilities PE (UT1) $100,000.00 Utilities CE (UT2) 0.00 No utility relocations anticipated Construction Total: $10,740,000.00 Construction Engineering (CE) $200,000.00 Other Considerations TOTAL: $11,340,000.00

This estimate includes removal and replacement of the existing shoulder pavement where needed, removal and replacement of the existing concrete median barrier where needed, fabrication and installation of the precast median inlets, removal and replacement of the existing longitudinal storm sewer pipe, and lining of the cross pipes using CIPP liner.

Environmental Issues This project will likely require preparation of a CE Level 2. The District or the District’s consultant will prepare an environmental document in accordance with the National Environmental Policy Act, National Historic Preservation Act, and other relevant laws. Because of anticipated work in the channel, a waterway permit will likely be needed. A final permits determination will be made during design.


Des #: 1592882 Page 5 of 6

No publicly owned parks, recreational areas or historic sites considered as Section 4(f) properties were identified within the project limits. A Section 4(f) analysis will not be necessary as part of the environmental documentation prepared for the project. A waters report and wetland delineation map will be required, as the I94 drainage system includes many low grade wetlands within the overall interstate corridor. A Rule 5 erosion control permit will be needed if 1 acre or more of ground is disturbed. Best management practices will be incorporated into the plans and constructed regardless of whether a Rule 5 permit is needed. Potential historic properties listed on or eligible for the National Register of Historic Places and the Indiana Register of Historic Sites and Structures are not known to be located within the project vicinity.

Right‐of‐Way Impact This project is not expected to require the purchase of right of way

Utilities There are no buried utilities within the I94 median or under I94 through the project limits. No utility conflicts are anticipated or expected.

Traffic Maintenance During Construction This project is considered a mobility significant project per IDM Chapter 81, and will require the development of a Transportation Management Plan (TMP). Due to the nature of the project, this work may be done under traffic with no lane closures. Traffic may be shifted up to one half lane width (six feet) away from the median, and the work zone protected by temporary concrete barrier (TCB). The work zone speed limit may only be reduced to 60 mph with the use of TCB; no further reduction of speed limit on I94 is required.

Other Projects There are no other projects currently programmed near/within the project limits.

PROJECT QUANTITY SUMMARY TABLE

STORM SEWER ABANDONMENT AND REMOVAL

Description This work shall consist of the abandonment of temporary and existing storm

sewer pipe and structures by removing or grouting pipe interior. Materials A cement based grout shall be used to fill the void of the temporary storm

sewer to be abandoned in place. The grouting material shall have a strength of at least 100 psi and shall have flow characteristics appropriate for filling a storm sewer. The grout mix design and method of installation shall be approved by the Engineer prior to beginning the operation.

Construction Requirements Remove the castings and portions of the temporary structures to allow for

milling and pavement operations. Fill the remaining section of temporary structure with grout. Temporary structures shall be abandoned prior to milling and paving operations.

The entire interior void space within the temporary and existing storm

sewer pipe located under the roadway and shoulders shall be filled with grout after the end is sealed. The grout shall cure and harden in the physical environment and prevent collapse of the pipe wall.

Temporary storm sewer pipe no longer in use and not filled with grout shall

be removed as shown on the plans or as directed. Method of Measurement The remove of castings and portions of the temporary structures will not be

measured for payment. Abandonment of pipe and temporary pipe removed will be measured by the

linear foot.

Basis of Payment The accepted quantities of abandon and grout filled and temporary pipe

removed will be paid for at the contract unit price per linear foot. Payment will be made under: Pay Item Pay Unit Symbol Pipe, Abandon and Grout Fill...............................LFT

Pipe, Remove, Temporary....................................LFT Removing casting and sections of the temporary structure and filling structure with grout shall be incidental to the pipe abandonment. Placing a bulkhead at the ends of existing pipe prior to grout fill shall be incidental to the pipe abandonment.

Casting and temporary pipe shall remain property of the Contractor upon completion of the contract.
