GENERAL – MISCELLANEOUS 1-1 PURPOSE These construction standards and prevailing specifications have been prepared to establish consistent design elements and other requirements for developers, contractors, utilities, and other private parties as well as for providing guidance for work within or affecting the City’s Right-of-Way. This document encourages standardization for design elements and consistency to ensure public safety, aesthetic appearance, proper drainage, and economical maintenance. The goal is to provide specific guidance and standards for consultants, contractors, developers, private individuals, and other entities that may require additional information, assistance, or direction through the administrative process for securing necessary City approvals. These standards and specifications do not and cannot provide for all situations and circumstances. They are intended to establish clear requirements for design and construction of public works throughout the City. These standards are not intended to minimize innovation or the creative skill of the design professional, but rather provide minimum requirements for compliance. 1-2 STANDING REFERENCES The following references and standards are referenced when pertinent, specifically cited, or when required by ordinance or other jurisdictional authority. 1.Local Public Agency Project Development Process Guidance Document for Local Federal-Aid Projects, Indiana Department of Transportation (INDOT), as amended. 2.INDOT Standard Specifications and Drawings, current edition. 3.A Policy on Geometric Design of Highways and Streets, American Association of State Highway and Transportation Officials (AASHTO). 4.Resolution No. 69-2015 – A Resolution of the Board of Public Works of the City of South Bend, Indiana Adopting a Complete Streets Policy, South Bend Complete Streets Policy, 2015. 5.Indiana Manual on Uniform Traffic Control Devices, "IMUTCD", as amended and approved by INDOT, current edition. 6.Guide for the Development of Bicycle Facilities, adopted by AASHTO, current edition. 7.Highway Capacity Manual (Special Report 209) published by the Transportation Research Board, National Research Council. 8.Roadside Design Guide published by AASHTO. 9.Urban Drainage Design Manual, U.S. Department of Transportation, HEC-22 circular, current edition. 10.Recommended Standards for Wastewater Facilities, Wastewater Committee of the Great Lakes – Upper Mississippi River.

Variance requests shall be made in writing and will require supporting documentation and/or justification as requested by the City. Submitted justifications shall include documentation specifying the criteria that will not be met, existing roadway characteristic, alternatives considered, comparison of safety and/or operational performance, other identified impacts, proposed mitigation measures, and compatibility with adjacent conditions. 1-4 FINANCIAL GUARANTEES AND PERMITS Parties performing work within the City Right-of-Way are required to provide permits and bonding per Chapter 18, Article 7 of the South Bend Municipal Code. The requirements for obtaining the appropriate and applicable permit(s) (i.e. right-of-way occupancy permit, excavation permit, etc.) are located in the municipal code and discussed in the below sections. A performance bond equal to 125% of the estimated construction cost, and a maintenance bond equal to ten percent (10%) of the estimated construction cost is required for all city work. Subdivision development and other work that will be later dedicated to the City shall require additional financial guarantees or surety bonds to ensure completion. For these types of projects, it is recommended that the developer meet with city staff for initiating, identifying, and establishing these financial guarantees. All requirements as noted in these construction standards and specifications and Chapter 21, Article 14 of the South Bend Municipal Code shall be followed by the developer. Below is a list of permits, with hyperlinks to the permit applications, that could be needed for a potential project. These applications are also available from the Division of Engineering. PERMIT TYPE •Excavation •Right-of-Way Occupancy •Sidewalk/Construction •Curb Cut Application •Private Encroachments •Special Trucking SECTION 1 – GENERAL MISCELLANEOUS 3 Consultants, and others performing work under a contract for the City directly, are required to secure the above permits, yet are exempt from respective application fees. 1-5 LIQUIDATED DAMAGES Work that is not completed by the established completion date can be subject to the assessment of liquidated damages in accordance with INDOT Standard Specifications Section 108.09 – Failure to Complete on Time. The liquidated damages assessed will be project specific and noted in the project’s special provisions. If a guarantor chooses to not complete construction, the guarantor will be responsible for damages incurred prior to completion. 1-6 QUALIFICATIONS Any contractor performing work within the City of South Bend shall be licensed with the State of Indiana and bonded with the City of South Bend Board of Public Works for the type of work being performed. The City of South Bend reserves the right to request all relevant qualifications and certifications from the contractor, their sub-contractors, and their employees. 1-7 R/W OCCUPANCY Right-of-Way Occupancy and Barricade Permits are administered by the City Engineering Office in accordance with Chapter 18, Article 7 of the South Bend Municipal Code. The application permit shall contain an adequate description of the occupied portion of the City's Right-of-Way, including size, location, purpose, and type of structure to be constructed within said Right-of-Way. Chapter 18, Article 7, Section 18-60 for additional information, required fees, and procedure for application.

The applicant shall pay fees whenever temporary obstructions exceed typical obstruction allowances that are inherent with construction activities as provided within the code. These fees are also further described in Chapter 18, Article 7, Section 18. 1-7.2 TRAFFIC CONTROL A permit application is also required prior to any use, restriction, or excavation within the City's Right- of-Way. This shall also include traffic control which is required for any work that restricts, redirects, or impedes vehicle or pedestrian travel in the Right-of-Way. Proposed restrictions shall have advance construction signage in accordance with IMUTCD and shall be submitted with the permit application for review. Extended Right-of-Way occupancy and traffic control may require a long-term occupancy, which requires approval from the Board of Public Works. 1-7.3 PRIVATE ENCROACHMENTS Private improvements - both permanent and temporary (e.g. brick mailboxes, building canopies, signs/banners, awnings, planters, underground utilities, signs, etc.) in the public Right-of-Way are subject to an encroachment permit. These types of improvements require a permit application and approval by the Board of Public Works. These improvements have additional indemnification requirements and when complete shall not impair the free flow of traffic within the Right-of-Way. The SECTION 1 – GENERAL MISCELLANEOUS 4 application for Encroachment Revocable Permit is located on the City’s website at https://southbendin.gov/board/public-works/. 1-7.4 FEE EXEMPTIONS City funded or city utility funded public improvement projects shall not be subject to city permit fees, yet the contractor must apply and receive approval for occupancy and other permits before working in the City’s Right-of-Way. For City projects, the Contractor performing the work is required to post bonds, surety, etc. and meet the City’s qualifications before performing the work. 1-7.5 CURB CUT APPLICATIONS All new approach construction requiring a curb cut or modification of an existing approach shall require a Curb Cut application which requires review and approval prior to the sidewalk/construction permits being issued. The permits are required before commencing with the work in the City’s Right- of-Way. All driveways and approaches shall be constructed in accordance with these standards – including provisions or correction for the pedestrian access route – as further described and provided in Section 2 - Streets, Walkways, and Paths. Notwithstanding any other provisions, driveways and approaches are not allowed across non-access easements, where prohibited by separate action, or where they are determined by the City Engineer to create a hazard or impede the traveling public on the roadway due to location or other considerations. The application can be found on the City’s Right-of-Way Permit Office webpage. 1-7.6 ADDITIONAL PERMITS AND FEES Depending on the nature of the work proposed within the City's Right-of-Way, additional permits and engineering review fees may be required. Additional information can be found on the City's website. 1-8 UTILITY WORK Utilities located in the City’s Right-of-Way shall be installed in accordance with these standards and other applicable ordinances. For general utility permitting, the Utility will be required to install the proposed facility as close as practical to be consistent with the typical sections in Section 2 - Streets, Walkways, and Paths. 1-8.1 MAINTENANCE OF TRAFFIC REQUIREMENTS In the use of the City’s Right-of-Way, utilities will be given consideration in conjunction with the traffic requirements of the adjacent roadway and nearby intersections. Both excavation and occupancy require traffic control and permits through the City’s Permit Office. Maintenance of traffic for both motor vehicles and pedestrians shall be provided when the proposed work interferes with either or both. 1-8.2 PERMITS BEFORE COMMENCING WORK All utilities – new placement, replacement, and extension – shall secure both state and local permit approvals for the above grade or below grade Right-of-Way occupations.

SECTION 2 – STREETS, WALKWAYS & PATHS 8 SECTION 2 – STREETS, WALKWAYS, AND PATHS 2-1 GENERAL 2-1.1 PURPOSE The purpose of this Section is to provide design guidance to developers and designers of projects impacting the Right-of-Way of the City of South Bend. All work within the City’s Right-of-Way shall comply with the following specifications. Work within the City’s Right-of-Way not addressed by the following specifications shall comply with INDOT’s Standard Specifications and Design Manual. Unless otherwise noted in these specifications, testing methods and criteria shall comply with INDOT’s Standard Specifications. 2-2 DESIGN REQUIREMENTS 2-2.1 GENERAL Design of streets, walkways, and paths shall comply with the City of South Bend Zoning Ordinance Article 14 - Subdivisions (Subdivision Ordinance), the Board of Public Works “Complete Streets Policy” (CSP), the current version of the Indiana Department of Transportation Design Manual (IDM), American Association of State Highway and Transportation Officials Policy on Geometric Design of Highways and Streets (Green Book), Federal Highway Administration’s 13 Controlling Criteria, the United States Access Board Public Right-Of-Way Accessibility Guidelines (PROWAG), and cited product manufacturer’s requirements. Any public land development adjacent to City streets, or otherwise making improvements within dedicated Right-of-Way upon disturbance or construction, shall be improved in accordance with these standards. When alley access is used, the developer is responsible for improving the alley to City standards consistent with street and public access provisions. Improvements shall extend the width of the developed parcel to the property line. A traffic impact study, subject to review and approval of the City Engineering Department, may be required for development that will impact safety or operational efficiency of City streets. Cited improvements to the impacted streets from the study shall be in accordance with the City Engineering Department requirements. All materials and work shall conform to these City Engineering Standards and Indiana Administrative Code (IAC) Requirements. 2-2.1 (a) COMPLETE STREETS Streets, walkways, and paths are an important part of what makes up South Bend’s neighborhoods. In this light, “Complete Streets” has been adopted to ensure that where possible all elements are provided as part of the city’s transportation facilities. These guidelines address the fundamental elements for safe transportation design yet also require other elements as part of design. Careful consideration shall be extended for the context and expected surrounding land use when reviewing requirements for walks, bike lanes (dedicated or shared), on street parking, and other amenities for proposed transportation facilities. For existing facilities that are being reconstructed or realigned, these additional features shall be considered and included as required with the proposed design. Exceptions from these SECTION 2 – STREETS, WALKWAYS & PATHS 9 requirements provided herein are further described in Section 1-3 Variance Process. These requests require supporting information, justification(s), and rationale for approval by the City. 2-2.2 STREET CLASSIFICATION Typically, street classification in the City of South Bend is based upon the context of the area served by the street and the amount and type of vehicular traffic. As the purpose of the street t ransitions from transit to commercial to residential, the classification and associated design criteria for the street also changes. Table 2-2.2 (1) below should be used to classify City of South Bend Streets: Table 2-2.2(1) Classification AADT Lanes Speed (mph) Notes Arterial >15,000 3 to 5 30-40 mph 25 mph* Major Streets per Subdivision Ordinance Design Vehicle: WB-65 (IDV) Collector 3,000-15,000 2 to 3 30 mph Design Vehicle: Incidental WB-40 Residential <3,000 2 25-30 mph Minor Streets per Subdivision Ordinance Design Vehicle: SU Alley NA 1 15 mph Design Vehicle: SU * Limited to Central Business District and Complete Streets Considerations. Arterial and Collector roadway functional classifications are maintained by the Federal Highway Administration through the Indiana Department of Transportation. In some instances, criteria will not be entirely met for a given classification. In these cases, the City will make the classification determination. 2-2.3 TYPICAL SECTION The typical roadway section for any given classification plays an integral role in achieving the desired functionality of a street. Vehicle speed, traffic volume, parking opportunities, and space available for various amenities are all closely tied to the street typical section. Table 2-2.3(1) below defines the desirable typical section for each street classification within the City: Table 2-2.3(1) Classification Right-of-Way Travel Lanes 2-way Left Turn Bike Lanes Parking No. Width Arterial 80 - 120 feet 4 11 feet Varies No No Collector 60.00 feet 2 11 feet 1 – 11 feet* Optional ** Varies Residential 50 - 60 feet 2 11 feet No Optional 2 – 8 feet Alley 1 12 feet No No No *Twelve (12) foot lane width should be considered where truck traffic warrants. ** Required on City designated bikeways and routes. Per the City’s Complete Streets Policy, sidewalks should be included along all streets unless specific exclusion is approved by the City Engineer. Sidewalks should desirably be located inside the Right-of-Way to allow room for repair of the sidewalk. It is strongly recommended that utilities be located underground outside the Right-of-Way in a separate easement. Underground utilities located in the parkway or tree-lawn should be located as near to the curb as possible to allow space for vegetation and ornamental light pole foundations near the sidewalk. Underground utilities within alleyways shall have be located a minimum of 18.00 inches below ground. Above grade SECTION 2 – STREETS, WALKWAYS & PATHS 10 utility facilities within alleyways or other public streets shall not conflict with service vehicle traffic, turning movements, and other property access provisions. 2-2.4 DESIGN SPEED The design speed of a roadway is the posted speed limit or the statutory required speed limit for streets without a posted speed limit. Table 2-2.4(1) below defines desired design speeds for each street classification within the City. Table 2-2.4(1) Classification Design Speed Arterial 40 mph Collector 30 mph Residential 30 mph Alley 15 mph If a posted speed is present, then the posted speed is the design speed. Based upon context and use, the City Engineer may determine and assign an alternate design speed as appropriate. 2-2.5 ROADSIDE SAFETY In compliance with the CSP, both new construction and spot improvements should “include facilities and amenities that are recognized as contributing to Complete Streets”, including lighting, trees, and other fixtures which are generally considered obstructions in terms of roadside safety. Streets within the City are generally curbed, have design speeds less than fifty (50) mph, and have minimal Right-of-Way. AASHTO makes provisions for curbed facilities, recommending obstructions be located as far from the traveled way as possible. At a minimum, roadside obstructions shall be three (3.00) feet behind the face of curb at intersections and driveway openings, and one and one-half (1.50) feet behind the face of curb elsewhere. Uncurbed facilities should comply with the AASHTO Roadside Design Guide. 2-2.6 SIGHT DISTANCE Stopping and intersection sight distance should be provided on all City streets in accordance with the Subdivision Ordinance and the IDM. A sight easement may be required for any portion of the sight triangle that falls outside of the Right-of-Way. 2-2.7 HORIZONTAL ALIGNMENT Horizontal alignment for subdivisions is subject to the Subdivision Ordinance. Alignment and horizontal curvature of other roadways shall typically comply with AASHTO’s design guidelines for Low Speed Urban Streets. Superelevation is not desired within the City and an effort should be made to design roadways that use a normal crown section. If a superelevated section is used, it should typically have a maximum rate of four percent (4%). For locations with reverse curves, a minimum tangent between curves of 100 feet for major streets and fifty (50) feet for minor streets is required, per the Subdivision Ordinance. SECTION 2 – STREETS, WALKWAYS & PATHS 11 2-2.8 VERTICAL ALIGNMENT The maximum desirable grade on residential streets and alleys is eight percent (8%). On all other streets, the maximum desirable grade is six percent (6%). The minimum desirable continuous grade is 0.5%. Vertical curvature for sags and crests shall comply with AASHTO’s design guidelines, Chapter 302 (44) of the IDM, and the Subdivision Ordinance. Vertical curve length shall desirably be three times the design speed and rounded up to the nearest quarter station [twenty-five (25) feet]. Compound vertical curves are not desirable and should have a tangent section of not less than twenty-five (25) feet between points of vertical curvature. 2-2.9 SIDEWALKS AND CURB RAMPS Sidewalk is required to be installed per City Standards the width of the developed parcel, and extend to the property line. If the site is located on a corner requiring a curb ramp, the developer is responsible for installing curb ramps. This may include the replacement of existing sidewalk or curb ramps if not PROWAG compliant. Curb may be required to be replaced if in poor condition. Sidewalks should be considered for all projects within the Right-of-Way. When not integral to the curb, the minimum sidewalk width is five (5) feet. When there is less than twelve (12) inches of separation between the sidewalk and the curb face, the minimum sidewalk width is six (6) feet. Sidewalks shall be designed to have a maximum design cross slope of one and one-half percent (1.5%) and a maximum running grade of five percent (5%), unless running parallel to a steeper roadway, in which case the walk profile would run parallel to the roadway grade. Vertical discontinuities will be limited to 0.25 inches or less. All sidewalks shall have a broom finish unless an alternate finish is approved by the City Engineer. Expansion joints shall be placed at a maximum spacing of forty (40) feet. Expansion material is required at all cold joints. Transverse control joints at least one-quarter (¼) of the concrete depth shall be placed at intervals approximately equal to the width of the sidewalk. Repairs or replacement of sidewalk shall be made to the nearest joint and the existing joint spacing shall be maintained. Curb ramps are required on each side of each intersection where sidewalks are present on opposite sides of the street, in order to provide an accessible route as defined by PROWAG. Cross slopes at curb ramps shall be designed to not exceed one and one-half percent (1.5%). Ramp grades shall be designed to not exceed seven and one-half percent (7.5%). Where turning movements are required at the top or bottom of a curb ramp, a turning area with minimum dimensions of forty-eight (48) inches by forty-eight (48) inches shall be provided, with a maximum slope within the turning area of one and one-half percent (1.5%). Detectable warning elements are required at each curb ramp in accordance with the City’s Standard Drawings. Orientation of the detectable warning element should be perpendicular to the direction of pedestrian travel when located less than five (5) feet from the back of curb. Transverse grooving beyond the detectable warning shall not be applied to concrete curb ramps. Other design elements for the curb ramp design shall be in accordance with the City’s Standard Drawings, INDOT Standard Drawings, and PROWAG. Colored concrete for sidewalks, curbs, and curb ramps shall be in accordance with the requirements of 2-5.3 PCCP, COLORED. Detectable warning elements shall be a suitable contrasting color where colored concrete is applied. SECTION 2 – STREETS, WALKWAYS & PATHS 12 2-2.10 INTERSECTIONS Intersection geometry shall be designed to accommodate the design vehicle through all maneuvers. Standard Drawings include some typical intersection geometries and treatments, though other options may be used subject to the approval of the City Engineer. Streets should intersect at an angle as close to ninety (90) degrees as possible, but desirably not at an angle less than eighty (80) degrees. Sight distance should be verified at all intersections impacted by an improvement in accordance with Chapter 46 of the IDM, and obstructions removed in order to provide the required intersection sight distance. See Section 2-2.6 Sight Distance for other provisions. For new developments or modifications to existing sites, intersections should be spaced not closer than 300 feet between the centerlines, except along Major or Arterial streets, where intersections should be spaced not closer than 400 feet. The designer should also consider traffic movements of the roadway and adjacent developments. New intersections should align with other existing roadways as a best practice. The grading of reconstructed signalized intersections should be tabled for both the major and minor approaches in order to provide smooth travel paths in all directions. Tabling should be accomplished by transitioning the cross slope of each travel lane from the typical slope to the tabled slope without abrupt changes and not exceeding maximum transition longitudinal grades within AASHTO. For two-way stop-controlled intersections, cross slope priority should be given to the uncontrolled approaches. Drainage should be considered for areas where cross-slopes are modified. 2-2.11 APPROACHES Residential approaches are not allowed within fifty (50) feet of an intersection, measured from the intersection of the extended street gutter lines and the point where the nearest side the approach intersects the street gutter line. Residential property lot approaches are limited to one (1) per street and one (1) per alley. “U” driveways will be considered on a case by case basis. Commercial approaches are not allowed within 100 feet of an intersection, measured between the intersection of the extended street gutter lines and the point where the nearest side the approach intersects the street gutter line. Commercial lots are limited to one (1) approach per street when the access frontage is less than 150 feet. Commercial lots are limited to two (2) approaches per street when the access frontage is greater than or equal to 150 feet, with forty (40) feet minimum distance between the approaches. Alley access shall be for destination use and not for vehicle site circulation or cut through routes. Parking adjacent to alleyways shall have defined approaches. Commercial approaches should be aligned with opposite commercial approaches or intersections and turning movements should be analyzed due to the proposed change in traffic. Approaches shall not impact the cross slope of sidewalks or pathways so that it exceeds one and one-half percent (1.5%). Ideally, sidewalks shall not change longitudinal grade through a driveway or other approach. Where not possible, affected sidewalks shall be reconstructed to the next joi nt required by a grade not exceeding five percent (5%). The maximum slope of an approach is eight percent (8%), unless approved by the City Engineer, with grade transitions minimized and a maximum algebraic grade difference of ten percent (10%). The desirable radius is twenty (20) feet and the minimum is ten (10) feet in constrained locations or adjacent to on-street parking. SECTION 2 – STREETS, WALKWAYS & PATHS 13 2-2.12 PRIVATE STREETS Private streets should be developed in accordance with current Green Book and IMUTCD standards, and will not be maintained by the City of South Bend. Intersections of private streets with City streets are subject to the policies within this document and require approval by the City Engineer prior to construction within the City Right-of-Way. 2-2.13 RIGHT TURN LANES Right turn lanes shall be provided where traffic studies indicate they are warranted and/or where directed by the City Engineer. Design shall comply with the relevant sections of the IDM, Green Book, and IMUTCD. 2-2.14 CUL-DE-SACS Cul-de-sacs are required at the termination of dead-end streets and shall comply with the appropriate City Standard Drawing. The geometry should be designed to accommodate an SU design vehicle. 2-2.15 SHARED USE PATHS / BICYCLE FACILITIES Shared use paths and bicycle facilities shall comply with Chapter 307(51) of the IDM. Bicycle racks, benches, lighting, and trail marking signs should be considered as appropriate and coordinated with the Department of Community Investment. Architectural elements require approval by the City Engineer. 2-3 SUBGRADE CONDITIONS AND TREATMENT Subgrade Preparation shall comply with the requirements of Section 207 of the INDOT Standard Specifications, except as follows: The natural soil in place may qualify as SUBBASE when the following conditions are met: a.Borings - A soil boring at intervals not to exceed 200 lf.

When concrete is used in replacement of asphaltic pavement, a blacking agent such as C 250 Super Black (Color Pigment, Inc.) or approved equal, shall be used. A clear seal membrane shall be utilized once the patch is finished (asphalt only). White pigment will be the only accepted seal for any concrete work performed in an existing concrete street. 2-6.1 (b) BRICK PAVEMENT PATCHING When excavating brick pavement, the existing brick shall be carefully removed and stockpiled prior to excavation. Salvaged brick shall be used for pavement replacement. Existing brick pavement designated for removal shall be salvaged undamaged. Care shall be taken to remove any bituminous material from brick pavers, including asphalt patches, asphalt overlay, and bituminous tack coat when directed by city staff. Salvaged brick shall remain the property of the City of South Bend and shall be stored off ground, covered, and on palettes for delivery to a location designated by the City. Where incorporated into the finished work and cross slope is not maintained due to a depression in the pavers, pavers shall be carefully removed, base material added and compacted, and pavers re- laid to a consistent cross slope in their original undamaged condition. Brick pavement to be restored shall be cleaned using an acid solution of ten percent (10%) Muriatic Acid and water to remove bituminous products and other foreign materials. 2-6.2 MAILBOXES Mailbox posts shall not be installed within one and one-half (1.50) feet of the face of curb. SECTION 2 – STREETS, WALKWAYS & PATHS 19 Monument or encased mailboxes not mounted on a pole or post may be permitted on residential roadways with speed limits less than thirty (30) mph, provided that the property owner accepts liability related to the mailbox, and the location of the mailbox does not conflict with the intersection sight distance requirements. Mailbox permits may be revoked at the City’s discretion. Mailboxes shall be entirely located behind the back of curb and are required to have the address number displayed. 2-6.3 DRAINAGE OUTLETS THROUGH CURBS Drainage outlets for the discharge of rainwater (e.g. yard and roof drains) through the curb face are not permitted. Property owners are required to maintain stormwater runoff on-site. Any discharge to the Right-of-Way requires approval by the Board of Public Works. 2-6.4 STAMPED CONCRETE Stamped concrete may be used within the city Right-of-Way, at locations as approved by the City Engineer. Concrete shall be in accordance with Section 604 of the INDOT Standard Specifications and 2-5.3 PCCP, COLORED as applicable.

A concrete mix design in accordance with current American Concrete Institute standards will be required for approval. 2-6.6 DECORATIVE PAVERS Decorative pavers may be used for non-motorized facilities and are subject to the design requirements of the application. The paver size, color, layout pattern, drainage characteristics, and pavement section shall be submitted to the City for approval. Paver materials shall be consistently colored throughout the section of each individual paver unit. Surface staining is not permitted. Paver installation without approval may be subject to removal. 2-6.7 PERMEABLE PAVEMENT Permeable pavement (Permeable Articulating Concrete Block/Mats) may be used within City Right- of-Way for non-travel lane applications. A geotechnical report demonstrating soil infiltration that meets the manufacturer’s recommendation is required for approval prior to use for the design and approval of the permeable pavement section. Perforated drain tile may be required in areas with marginal soils. A surface inlet is required at sag locations. A thirty-six (36) month Maintenance Bond shall be provided to the City for permeable pavement installations at the completion of construction. The Maintenance Bond shall be for an amount equal to not less than 10% of all costs associated with the permeable pavement installation. A thirty-six SECTION 2 – STREETS, WALKWAYS & PATHS 20 (36)month (minimum) maintenance program shall be provided to the City that includes visual inspection reports with photos and a recommended cleaning schedule. SECTION 3 – STORMWATER 21 SECTION 3 – STORMWATER 3-1 STORMWATER QUANTITY MANAGEMENT 3-1.1 STORMWATER STORAGE POLICY This manual was created to assist engineers planning and designing non-residential (re)development plans. This manual addresses the minimum stormwater quantity design requirements. This manual does not address stormwater quality impacts. However, minimizing a site’s impact to our community waters is strongly encouraged and shall be considered when reviewed by City staff. When unexpected or complex site issues arise, the applicant/applicant’s designer is responsible for identifying such conditions in advance and shall obtain approval of the City Engineer for approach before continuing design. It is recognized that most streams, drainage channels and storm sewer systems in the City of South Bend do not have sufficient capacity to receive and convey stormwater runoff resulting from continued urbanization. This manual is meant to reduce negative impacts of flooding on private property, local infrastructure, and natural resources. Accordingly, the storage and controlled release of excess stormwater runoff shall be required for all developments and redevelopments where land disturbance is greater than 2,500 square feet. 3-1.2 CALCULATION OF REQUIRED STORAGE VOLUME: SIMPLE METHOD Sites less than 5 acres releasing by infiltration and evaporation only, that do not have a concentrated outfall and that are not located in a wellhead protection area are eligible to use the Simple Method to calculate the amount of required storage volume. Facilities shall be adequately sized to store the entire volume from a 25-year, 24-hour rainfall without any release. All impervious areas, excluding Public right-of-way shall be directed to the storage facility. The storage volume required shall be calculated using the Simple Method as calculated in Table 1. The Simple Method storage volume calculations shall account for off-site runoff that flows through the site. Note that the Simple Method of Required Storage Volume is a special case of the Modified Rational Method, where the release from the storage facility is not considered. If an Engineer wishes to consider the release of infiltrated runoff in the sizing of a storage facility, the Standard Method in Section 4 shall be used. Table 1: Storage Volume Required Land Use (1) Area (square feet) (2) Runoff Coefficient C (3) Rainfall Depth 25-yr, 24-hr (inches) Storage Volume Required (1)x(2)x(3)/12 (cubic feet) Impervious Surface 0.9 4.90 Pervious (Grass) 0.2 4.90 Total = cft For sites greater than 5 acres or that have a concentrated outfall refer to Section 4 for Standard Method design criteria. 3-1.3 CALCULATION OF DESIGN STORAGE VOLUME PROVIDED Facilities shall be designed to store the volume required in Section 2. 6% of the calculated storage volume shall be added to the total volume of the storage facility to account for siltation. Dry storage facilities (detention basins, subgrade detention, etc.) shall be designed in such a manner that the SECTION 3 – STORMWATER 22 storage facility is dry within 48 hours of a 100-year storm event. All wet storage facilities (retention basins) shall be designed to resume the designed water elevation within 48 hours of a 100 -year storm event. The storage volume provided by a storage facility is a function of the water elevation. A stage (elevation) storage table should be calculated using the average area method. The following is a formula for the average area method. The interval between intermediate elevations should not exceed one foot. V= storage volume 𝑉=∑∆𝐻(𝐴1+𝐴2) 2 ∆𝐻=Elevation2-Elevation1 A= surface area at a given elevation The cumulative storage should be calculated by summing the storage volume at each elevation. For wet storage facilities, only the volume provided above the ordinary water level is considered in the storage volume calculations. A stage storage table showing all storage above the ordinary water elevation should be shown and the total volume of that storage should be equal to or greater than the calculated storage volume required. 3-1.4 CALCULATION OF REQUIRED STORAGE VOLUME: STANDARD METHOD Due to uncertainties of future development patterns and the associated proposed stormwater quantity and quality management systems within a watershed, it is the policy of the City of South Bend to discourage release of runoff from a new development or redevelopment other than by infiltration up to the 100-year storm event. However, the City Engineer may approve a controlled release from a storage facility when the engineer can show that the downstream receiving system has adequate capacity to accept the calculated discharge from the storage facility. At no time shall an increased rate of discharge be directed to a combined sewer system or storm sewers that drain to combined sewers. 3-1.4 (a) CONTROL RELEASE CALCULATIONS 1.) The same hydrologic method shall be used for runoff peak determination for both pre - developed and post-developed condition calculations. 2.) Recommended hydrologic methods i.The Rational Method is acceptable for calculating peak flows when the total tributary drainage area is 5 acres or less and the tributary drainage area has no existing depressional storage. Runoff coefficients for analysis are shown in Table 2 and are adopted from the INDOT Design Manual. Table 2: Runoff Coefficients for Rational Method Land Use Runoff Coefficient “C” Park, Lawn, Grassy Area 0.2 Residential Single Family 0.4 Apartment or Multi-Unit 0.7 Business, Commercial or Industrial 0.8 Pavement 0.9 SECTION 3 – STORMWATER 23 ii.Runoff Hydrographs and Flood Routing Analysis a.) This method shall be required when any of the following apply: •If the total tributary drainage area is greater than 5 acres •If there is existing depressional storage •If offsite flows are detained in storage facilities •If proposed flows travel through multiple storage facilities b.) The USDA Natural Resource Conservation Service (NRCS) method (also known as the SCS method) shall be used for calculating runoff and generating hydrographs. Refer to the USDA NRCS National Engineering Handbook (NEH-4) publication for additional information. •The use of proprietary software is discouraged. •Allowable open source software recommended for use include: TR-20, HEC- HMS and EPA-SWMM. 3.) Rainfall Depths shown in Table 3 shall be utilized to determine total rainfall depths for South Bend. These values are derived from NOAA Atlas 14, published by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration, and National Weather Service. Table 3: South Bend 24-Hour Rainfall Depth Frequency Rainfall (years) (inches) 2 2.81 10 4.09 25 4.90 100 6.27 4.) The rainfall distribution used for the Design Storm should be the median first quartile 24-hour rainfall distribution published in the latest publication of NOAA Atlas 14. The Rainfall Distribution shown in Table 4 shall be utilized in the hydrologic analysis to Design Storm characteristics and the calculation of release rates from the Design Storm. SECTION 3 – STORMWATER 24 Table 4: NOAA Atlas 14 First Quartile, Median 24-hr Rainfall Distribution Cumulative Time (%) Cumulative Precipitation (%) 0% 0% 5% 12% 10% 27% 15% 40% 20% 51% 25% 61% 30% 68% 35% 73% 40% 78% 45% 82% 50% 85% 55% 88% 60% 91% 65% 93% 70% 95% 75% 97% 80% 98% 85% 99% 90% 99.5% 95% 99.8% 100% 100% 5.) Allowable Concentrated Release Rate i.Calculations shall be performed for a 24-hour duration storm for existing and proposed conditions to determine discharge rates produced and storage required. ii.The maximum allowable release rate for storage facilities shall not exceed the downstream channel capacity or 10-year predeveloped rate. Note that releases from the storage facility due to infiltration are not considered as part of the release rate requirement because they are not part of the concentrated discharge release at the outlet. iii.Discharge control structures shall be multi-stage and capable of limiting 2, 10, and 100-year storms to the minimum requirements outlined in the previous section. SECTION 3 – STORMWATER 25 iv.It is preferred that runoff from upstream tributary areas (off-site land areas) be bypassed around the storage facility of a site. If this is not feasible, the off-site runoff can be routed through the storage facility but would be subject to the storage release rate requirements as if it were part of the development in question. a.) If the inlet invert is below expected storage facility water elevations, the contributing storm network’s hydraulic grade line shall be reevaluated to ensure there are no negative impacts. v.Infiltration Routing (dry storage facilities only) a.) If the Engineer wishes to consider the release of runoff through the infiltration process in a dry storage facility, the infiltration rate shall be as recommended in a geotechnical report, certified by a Professional Engineer based upon site specific soil borings. The number of soil borings shall be adequate to represent the storage facility infiltration characteristics. The soil boring(s) shall be positioned at the proposed storage facility location and in-situ soils shall be used with the proposed storage facility. b.) The infiltration discharge shall be the area of inundation along the side slopes of the storage facility for a given elevation. The storage facility bottom shall be excluded from infiltration release calculations. c.) If there is both a proposed concentrated flow outlet (ex. Discharge pipe) and infiltration considered in the elevation-release rate calculations, the total release from the storage facility at a given elevation would be the summation of the infiltration release rate and the concentrated outlet (pipe) release rate. While the routing should consider the total release in order to size the storage facility, the calculations shall clearly provide a tabulation of infiltration release and concentrated pipe release rates for each elevation considered in the routing analysis to ensure that the allowable concentrated release rates have not been exceeded at any outlet. 3-1.4 (b) ALTERNATIVES TO REQUIRED STORAGE 1.) For a project site that does not lend itself well for stormwater storage or to the entire calculated required storage volume, the engineer shall propose alternative methods to control the release rate and avoid downstream impacts. Any alternative methods shall require the approval of the City Engineer. 2.) When the City Engineer approves an alternative method, a fee computed for each acre-foot or part thereof of stormwater storage volume as required but not provided shall be paid as established and allowed by City Ordinance. SECTION 3 – STORMWATER 26 3-1.5 FLOOD ROUTING AND EMERGENCY SPILLWAY 1.) Stormwater basins shall have a secondary outfall (emergency spillway) that is designed to pass the peak 100-year inflow. 2.) The spillway must direct the emergency overflows away from buildings and other structures. 3.) Overflow paths throughout the development resulting from the peak 100-year storm event, shall be determined, clearly shown on the plans and contained in permanent drainage easements. 4.) Emergency spillways must be resistant to vertical movement; concrete grade beams, if present, must extend below frost line. 3-1.6 FREEBOARD AND FLOOD PROTECTION GRADE 1.) Stormwater storage facilities shall have a minimum of 1-foot freeboard. Freeboard is the vertical difference between the storage facility’s top and the water surface resulting from the peak 100-year passing over the emergency spillway. i.All berms and levees shall not be considered a regulated dam as specified in Indiana Department of Natural Resources’ (IDNR) Indiana Dam Safety Inspection Manual. 2.) All buildings adjacent to a stormwater storage facility or in the overflow path shall have a Minimum Flood Protection Grade established. The elevation shall be 2 feet above the water surface elevation of the peak 100-year inflow passing over the emergency spillway (1 foot above the freeboard elevation). SECTION 3 – STORMWATER 27 3.) Minimum Flood Protection Grade applies to the lowest opening of a building that surface water could enter a basement window, walkout basement doorway or structure’s finished floor, whichever is lower. 4.) The plans shall list the proposed Base Flood Elevation on each lot. 3-1.7 FLOODPLAIN AND FLOODWAY The Flood Control Act (IC 14-28-1) regulates various development activities (i.e. structures, obstructions, deposits, and/or excavations) within the 100-year floodway of any waterway by requiring IDNR approval prior to the beginning of the project. Permits issued under the Flood Control Act are called Construction in a Floodway (CIF) permits. IDNR evaluates projects to protect the floodway from undue restrictions and environmental impacts. A CIF permit could be required for any waterway with an upstream drainage area equal to or greater than one (1.0) square mile. 1.) It must be determined whether the development site is affected by the Flood Control Act by evaluating if it is near a waterway with a watershed area in excess of one square mile. The DHS FEMA flood plain maps do not include all flood plains regulated by the IDNR. The City has developed a GIS layer to use as a guide in determining whether a waterway is regulated by the IDNR due to contributing drainage areas. For sites that may be in a waterway regulated by the IDNR, the engineer shall provide the appropriate survey information and calculations to the DNR and obtain concurrence for the calculated the 100-year flood elevation. 2.) For sites along waterways with a contributing drainage area greater than one square mile, the developer of such site shall provide the City with a copy of the CIF permit from the DNR prior to final approval, or a letter from the DNR indicating that the site does not appear to require such approval. SECTION 3 – STORMWATER 28 3-1.8 STORAGE FACILITY REQUIREMENTS 1.) Detention Basins Design i.Minimum longitudinal and transverse bottom slopes of 1.0% unless underdrains are provided ii.Vegetated side slopes of the basin shall not exceed 4 foot horizontal to 1 foot vertical (4:1) iii.Storage depth shall not exceed 4 feet without approval 2.)

Outlet control structures shall be designed to operate as simply as possible without manual operation and shall require little or no maintenance and/or attention for proper operation. 4.) The storage facility owner shall be responsible for storage facility access and maintenance, including the removal of accumulated sediment and debris. The owner shall maintain records of storage facility maintenance operations and provide them to the City upon request. The City may perform periodic inspection of storage facilities and require sediment removal and associated storage facility maintenance at the owner’s expense. 5.) A geotechnical investigation should be performed to determine the anticipated soil conditions at the site. If infiltration release is considered in the calculation the geotechnical investigation should provide recommended infiltration rates. At a minimum, soil maps from USGS should be provided, along with the anticipated soil infiltration rates to be encountered. If soils within Soil Groups C or D are indicated, infiltration may not be a viable option. 6.) A storage facility located adjacent to a roadway should be provided with an adequate recoverable slope or clear zone offset from the AASHTO Roadside Design Guide to minimize SECTION 3 – STORMWATER 29 the accidental entry of an errant vehicle. (INDOT Hydraulic and Drainage Design 203- 5.03(07)). 3-1.9 ADDITIONAL CONSIDERATIONS 1.) All impervious area of the site, excluding Public right-of-way, shall drain through a storage facility. 2.) If the site is within a wellhead protection area, infiltration may not be used unless specifically allowed by the City Engineer. 3.) All compartmentalized chambers of underground storage facilities shall have inspection ports with a minimum clear opening of 24-inch diameter and shall be sized to accommodate physical removal of grease, debris, solids and pollutants that may enter the storage facility . 4.) For storage within gravel beds, only the open void space shall be included in the available storage calculation. Use of uniform grade stone with a maximum porosity of 35% shall be used in calculations. Dense graded aggregate shall not be considered for storage. 5.) For sites not located within wellhead protection areas, paved parking lots may be designed to provide temporary storage of storm waters that exceed the peak 100-year storm event. Outlets will be designed so as to empty the stored waters slowly. Depths of storage shall be limited to a maximum depth of 4 inches. Ponding should, in general, be confined to those areas of the parking lots furthest from the area served. 6.) Refer to Section 17-4 of the Ordinance for information about the City’s Long Term Control Plan, including drain and downspout disconnect requirements. 3-2 STORMWATER QUALITY Section under development. 3-3 STORMWATER TECHNICAL 3-3.1 DESIGN REQUIREMENTS Design of the Stormwater System shall comply with the current version of the City of South Bend Ordinance, Issuance of Permits, Construction and Permit Requirements, and product manufacturer’s requirements. 3-3.2 MATERIALS 3-3.2 (a) PIPES AND FITTINGS – GRAVITY FLOW Pipe and fitting materials shall conform to the requirements of INDOT Standard Specifications Section 715.

SECTION 4 – SANITARY 66 6.) The polyamine epoxy used to coat the manhole adjusting rings shall be applied per manufacturer’s recommendations. 7.) If necessary, subsequent top coating or additional coats of the protective coating should occur as soon as the basecoat becomes tack free, no later than the recoat window for the specified products. Additional surface preparation procedures will be required if this recoat window is exceeded. 8.) At the termination of each material, a construction joint shall be installed to ensure the coating is an airtight barrier to protect the existing structure material. 9.) If the upstream and downstream pipe connections have been lined, the protective manhole coating shall be applied to overlap and secure the lining material to the manhole as well as reestablish/reconstruct the inverts. 10.) When groundwater loading is not an issue and only a corrosion barrier is required, the rehabilitation lining shall be installed to the thickness necessary to qualify as a monolithic (void free) liner. The roughness of the substrate will dictate the thickness needed to create the monolithic liner and eliminate any opportunity for voids in the lining. The minimum value for coating thickness, for corrosion protection, and for non-structural rehabilitation, shall be 125 mils and 150 mils on average. 4-3.13 LIFT STATIONS Section under development. 4-4 TESTING 4-4.1 TRENCH COMPACTION 4-4.1 (a) TESTING REQUIREMENTS 1.)

Remove organic, unstable or unconsolidated material from site, verify conformance of subgrade preparation, compacted density and elevations to specified requirements. 2. Clean and re-use existing street brick pavers removed during site demolition. Remaining pavers not used will be returned to the City. 3. Place Compacted Aggregate No. 53 to lines and grade. 4. Spread #12 limestone chips evenly over crushed stone base course and screed rails. (Screed to 1 inch minimum thickness) a. Do not spread #12 limestone chips beyond area to be covered by pavers the same day. Prior to recommencement of work, remove, replace and re-screed #12 limestone chips not covered with pavers the previous work day. b. Do not disturb screeded setting bed. Re-screed disturbed setting bed. 4.Lay pavers by hand in pattern(s) matching existing layout. a.Lay full pavers first. b. Mix pavers from at least two pallets to produce uniform color blends. 5. Provide 116 inch to 3 16 inch wide joints between pavers. Adjust pavers to form straight bond lines and appropriate joint widths. Maximum bond line variation shall be +-_ inch over a 50 foot string line. 6. Fill gaps at paved area edges with cut pavers. a.Cut pavers shall not be smaller than 1 3 (one-third) of a whole paver except wherepattern is to be maintained and a smaller piece is surrounded by a full paver and concrete banding. 7. Do not permit traffic, including construction equipment, on pavers before initial compaction and joint filling. Disturbed areas of pavers shall be taken up, the setting bed re-screeded and pavers re-laid. 8. Vibrate pavers into setting bed using a high frequency/low-amplitude plate compactor capable of 3,000 lbf to 5,000 lbf at a 75 to 100 Hz frequency. Protect pavers from chipping during compaction by using a rubber matt, rubber rollers or other approved materials placed over pavers. Do not compact within 6 feet of unrestrained edges. Remove cracked or damaged pavers and replace with new units. 9. After pavers are fully settled and free from movement, simultaneously spread, sweep and compact dry #12 limestone chips into joints until they are completely filled and chips no longer falls into joints. 10. Protect areas not covered with cut and compacted pavers with waterproof covering overnight.

Dig a shallow depression (about 3 to 5 inches deep), remove all debris, and lay the filter sock into it. 3. Secure filter sock with wooden stakes. 4. Terminating ends should be turned uphill (min. 6") to prevent runoff from flowing around the ends. 5. Seat the filter sock with foot tamped backfill on the upstream side such that water will not run under it. Recommended wattle spacing by slope: Slope 9" Dia.12" Dia. Less than 4:1 20 ft. 40 ft. 2:1 to 4:1 15 ft. 30 ft. 2:1 or Greater 10 ft. 20 ft. MAINTENANCE: Sediment should be removed on a routine basis when the level of the sediment reaches one half the height of the exposed filter sock. Damaged areas should be repaired immediately until vegetation is established and growing through the material. MATERIALS: Filter socks can be from straw, rice straw, coconut husks or other approved material. The netting consists of biodegradable burlap, or high density polyethylene and ethyl vinyl acetate containing ultraviolet inhibitors. Straw should be certified weed free forage, by a manufacturer whose principle business is wattle manufacturing. Coir (coconut fiber) can be in bristle and mattress form and should be obtained from freshwater cured coconut husk. DESCRIPTION: Filter socks are also known as straw worms, bio-logs, straw noodles, or straw tubes. They are a sediment velocity control device made of tubes of straw, rice, or coconut husk encased in an ultraviolet degradable plastic netting or 100% burlap material. Filter socks may be suitable along the toe, top, face, and at grade breaks of exposed erodible slopes to shorten slope length and spread runoff as sheet flow; at the end of a downward slope where it transitions to a steeper slope; along sidewalks and curbs to prevent sediment from washing into gutters; around storm drains and drop inlets; down-slope of exposed soil areas; around temporary material spoil and stockpiles, such as topsoil and for stream bank protection. Note: Filter Socks may be used in lieu of silt fence if desired. 10' Min.Varies Per Site Layout10 Mil Plastic Lining (Typ.) Stake (Typ.) Straw Bale (Typ.) Staples (2 per Bale) 1 8" Dia.
