CHAPTER 1:

INTRODUCTION

1.1 Mission

Job Corps is a national residential training and employment program administered by the Department of Labor (DOL). As a national, primarily residential training program, Job Corp’s mission is to attract eligible young adults, teach them the skills they need to become employable and independent, and develop careers or prepare them for further education. It addresses the multiple barriers to employment faced by disadvantaged youth throughout the United States. Job Corps was originally established by the Economic Opportunity Act of 1964; authorization for the program continued under the Comprehensive Employment Training Act, then Title IV-B of the Job Training partnership Act, and is currently provided for under Title I-C of the Workforce Investment Act, 1998.

1.2 Purpose of Handbook

The U.S. Department of Labor, Office of Job Corps “Planning, Design and Construction Administration Guidelines” contains guidance, procedures and policies that Architects/Engineers providing services to the Department of Labor must adhere to in the planning, design and construction of Job Corps specific projects.

This Handbook also defines technical standards which establish levels of planning, design and construction quality and performance of materials and systems incorporated into new, expansion of, or modification to facilities at Job Corps Center (JCC) sites. Standards are also applicable to work performed under the Vocational Skills Training (VST) program.

This Handbook supercedes all previous planning, design and construction administration guidelines, written or verbal. Requests for interpretations of the guidelines or proposed deviations are to be directed to the Engineering Support Contractor (ESC) on behalf of the National Office of Job Corps. Proposed deviations are to receive approval by the COTR for Job Corps prior to any financial or promissory commitment.

1.3 Renovation Versus New Construction

Guidelines for renovation of existing facilities shall be consistent with the guidelines for new construction as outlined in this Handbook. Special or unique requirements for renovation which deviate from the guidelines for new construction are addressed in the following chapters. When it is determined by the Architect/Engineer (A/E) or by the Engineering Support Contractor (ESC) during the Planning and Design process for renovation, that utilization of a specific system, material and/or equipment is not feasible in meeting the guidelines, the A/E shall submit a recommendation to the ESC. The written

1-2 recommendation shall include a physical and/or financial justification why following the criteria is not feasible and recommend an alternative solution(s).

1.4 Codes and Policies

The A/E providing planning, design and construction administration services shall conform to all applicable codes, ordinances and regulations. When constructed on leased land and where local, county or state regulations are more stringent than those of the Federal Government, regulations of the local, county or state that the Lessor is required to comply with shall govern. When constructed on Federal Government land, the more stringent regulations are to receive concurrence from DOL before being incorporated into the final design. Reviews, comments, and approvals, or lack thereof by DOL or its Engineering Support Contractors, does not relieve the A/E of responsibility for meeting the above requirements.

The U.S. Department of Labor requires that all construction conform to the latest regulations of the Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the National Institute for Occupational Safety and Health (NIOSH). Where regulations of the state or local authority are more stringent than those of the federal government, regulations of the state or local authority shall prevail.

1.5 Regulatory Permits and Licenses

Job Corps centers are located in facilities either owned by the Federal Government or leased from non-Federal Government entities. In the case of federally-owned properties, no State or local building or zoning permits are normally required to provide a fully functioning center at the conclusion of construction. On the other hand, construction projects at centers in leased facilities or located on leased properties do normally require permits and/or licenses. In either case, however, any construction-related impact to adjacent neighboring properties or other off-site areas, including utility connections, requires due diligence to determine what, if any, permit or license requirements exist.

Whether the subject project is on a federally-owned or leased property, the A/E shall, upon Notice to Proceed, conduct a thorough research and formal inquiry with any and all applicable agencies in order to determine all regulatory, permitting, and licensing requirements necessary for the successful, timely, and uninterrupted implementation of the project. The DOL will provide the A/E any applicable portions of leases and/or any legal agreements with local authorities.

The A/E is required to identify all such process actions and present its findings during the 15% Schematic presentation. The A/E will submit with their narrative a matrix of all required project permits and/or licenses, reviewing agencies, fees, hours for preparation by the A/E, and whether the permit and/or license will be applied for by the A/E, the A/E’s representative, or the Contractor. The matrix shall also indicate the required review and

1-3 processing times for said agencies. In conjunction with the matrix, the A/E shall submit a schedule with regulatory requirements for permit and/or license approval by the governing agencies. This research effort shall be part of the A/E’s base contract fee.

Upon approval of the 15% Schematic submittal, DOL will provide further instruction to the A/E via a written directive. Upon receipt of the directive, the A/E shall proceed and/or assist where applicable in securing all permits and/or licenses as deemed necessary. If warranted, the A/E may submit a Request for Change (RFC) proposal so that a modification to their contract can be issued to equitably compensate this permit application effort.

Any and all regulatory agency comments received as a result of their reviews shall be forwarded only to DOL for review and approval prior to their incorporation into the contract documents. Where DOL elects not to secure certain permits or licenses, the A/E shall duly record such requests. The A/E shall not conduct any further communications, verbal or written, with the governing agency without the prior consent of DOL.

The following charts outline many of the types of issues that are to be addressed by the A/E.

These items are informational only and not meant to be all inclusive. The A/E shall be responsible for conducting thorough and comprehensive research into all applicable permit and/or license requirements for each project.

1.6 Historic Preservation

DOL is committed to adhering to the Standards of Code of Federal Regulations for Historic Preservation as they relate to the design, construction and rehabilitation of historic buildings on Job Corps center sites. It is the responsibility of DOL to afford the Advisory Council on Historic Preservation a reasonable opportunity to comment on any project affecting a facility that is included in, or is eligible for inclusion in, the National Register.

The A/E shall advise DOL of any buildings being considered for renovation or demolition which may potentially be included in, or may be eligible for inclusion in, the National Register. The A/E should advise DOL immediately if it appears that an activity may impact a Nationally Registered Site, or is not in keeping with the Advisory Council on Historic Preservation, State Historic Preservation Officer Administration, or The Secretary of Interior’s Standards and Guidelines for Archeology and Historic Preservation.

1.7 Planning and Design Philosophy

In support of the mission and purpose of JCCs, the physical environment created by planning and design efforts is to primarily create an environment which integrates the development of academic, vocational and social skills, and optimizes time spent in the environment with a positive and productive experience for each student. In addition, the planning and design should provide quality facilities which are cost effective with regard to construction, operations, and maintenance. To accomplish this, the following primary parameters for facilities are essential:

• Provides a safe and comfortable environment

• Provides an environment conducive to educational and personal achievement

• Facilities are cost effective and efficient with regard to constructability, operations, and maintenance

1-5

• Designed to avoid institutional character or atmosphere

• Designed to reflect local architectural, cultural, and historical characteristics

• Materials, surface treatments, and finishes that address climatic conditions and severe and/or adverse use.

The quality of the site and building designs should make a positive contribution to the surrounding urban, suburban, or rural landscape.

Three characteristics usually distinguish Job Corps facilities: long life span, changing occupancies, and limited maintenance resources. DOL generally owns and operates its facilities much longer than private sector owners. Accordingly, a higher level of durability is required for all systems.

1.8 High Performance and Sustainable Building Design

The Department of Labor is committed to providing Federal leadership in planning, acquiring, siting, designing, building, operating and maintaining high performance and sustainable buildings. The guiding principles of this initiative are to: 1) employ integrated design principles; 2) optimize energy performance; 3) protect and conserve water; 4) enhance indoor environmental quality; and 5) assess all building materials for their durability and their value as a “green” product to lessen the environmental impact. Within the constraints of the design-to budget, the A/E shall design according to the following guidelines in these five areas. Where significant opportunities exist that would require additional funding above the design-to funding level, the A/E shall notify DOL of the potential opportunity and the commensurate cost.

1.8.1 Employ Integrated Design Principles

• No later than the 15% design submission, the A/E will propose performance goals for siting, energy, water, materials, indoor environmental quality, and comprehensive design.

• The A/E will recommend total building commissioning practices tailored to the size and complexity of the building and system components.

• During the construction administration portion of the contract, the A/E will verify performance of building components.

o The A/E and ESC will be jointly designated commissioning authority.

o The A/E will include commissioning requirements in construction documents.

o The A/E will develop a commissioning plan.

o The substantial completion/commissioning will include verification of installation and performance of all systems.

o The A/E will submit a commissioning report.

1-6

1.8.2 Optimize Energy Performance

• No later than the 15% design submission, the A/E will propose a whole building performance target for intended use, occupancy, operations, plug loads, and other energy demands.

• The A/E shall design to earn Energy Star® targets for new construction and renovation where applicable.

• The A/E shall reduce the energy cost budget by 30 percent compared to the baseline building performance rating per the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., (ASHRAE) and the Illuminating Engineering Society of North America (IESNA) Standard 90.1-2004, Energy Standard for Buildings except Low-Rise Residential for new construction.

• The A/E shall reduce the energy cost budget by 20 percent below pre-renovations 2003 baseline for major renovations.

• The A/E shall specify the installation of building level utility meters in new major construction and renovation projects to track and continuously optimize performance (In accordance with DOE guidelines issued under section 103 of the Energy Policy Act of 2005 (EPAct)).

1.8.3 Protect and Conserve Water

• The A/E shall employ strategies that in aggregate use a minimum of 20 percent less potable water than indoor water use baseline calculated for the building, after meeting the Energy Policy Act of 1992 fixture performance requirements.

• The A/E shall reduce outdoor potable water consumption by a minimum of 50 percent over that consumed by conventional means by using water efficient landscape and irrigation strategies including water reuse and recycling.

• The A/E shall employ design and construction strategies that reduce storm water runoff and polluted site water runoff.

1.8.4 Enhance Indoor Environmental Quality

• The design shall meet current ASHRAE Standard 55-2004, Thermal Environmental Conditions for Human Occupancy, including continuous humidity control within established ranges per climate zone.

• The design shall meet ASHRAE Standard 62.1-2004 Ventilation for Acceptable Indoor Air Quality.

• The A/E shall establish and implement a moisture control strategy for controlling moisture flows and condensation to prevent building damage and mold contamination.

• The design shall achieve a minimum daylight factor of 2 percent (excluding all direct sunlight penetration) in 75 percent of all space occupied for critical visual tasks.

1-7

• The design shall provide automatic dimming controls or accessible manual lighting controls, and appropriate glare control.

• The A/E shall specify materials and products with low pollutant emissions, including adhesives, sealants, paints, carpet systems, and furnishings.

• The A/E shall follow the recommended approach of the Sheet Metal and Air Conditioning Contractor’s National Association Indoor Air Quality Guidelines for Occupied Buildings under Construction (1995).

• The design shall specify that the contractor conduct a minimum 72 hour flush out with maximum outdoor air consistent with achieving relative humidity no greater than 60 percent after construction and prior to occupancy.

1.8.5 Assess Building Materials for Durability and Value as a “Green” Product to Lessen

Environmental Impact

• The A/E shall specify products meeting or exceeding EPA’s recycled content recommendations for EPA-designated products.

• The A/E shall specify materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (based on cost) of the total value of the materials in the project.

• The A/E shall specify products meeting or exceeding USDA’s biobased content recommendations for USDA-designated products.

• The A/E shall specify biobased products made from rapidly renewable resources and certified sustainable wood products for other products.

• The A/E shall identify local recycling and salvage operations that could process site related waste during a project’s planning stage and specify their use.

• The A/E shall specify in the design to recycle or salvage at least 50 percent construction, demolition, and land clearing waste, excluding soil, where markets or on-site recycling opportunities exist.

• The design shall eliminate the use of ozone depleting compounds during and after construction where alternative environmentally preferable products are available, consistent with either the Montreal Protocol and Title VI or the Clean Air Act Amendments of 1990, or equivalent overall air quality benefits that take into account life cycle impacts.

1.9 Prototypes

In order to better convey the Job Corps programmatic requirements for each facility, DOL is in the process of developing prototypes for the various functions of the typical Job Corps Center. The prototype documents will contain design components that provide conceptual plans, elevations, and sections – typically developed to the schematic level. The conceptual elements will also include information that defines adjacencies, spatial analyses, design intent and objectives. Each prototype will provide a “kit of parts” that can be used in various defined combinations to produce prototypical building designs. This will allow A/Es to

1-8 freely create and develop unique design solutions while complying with very specific programmatic guidelines.

When applicable, a specific prototype package will be incorporated into an A/E contract by inclusion in the Statement of Work (SOW).

CHAPTER 2:

CIVIL DESIGN CRITERIA

2.1 Introduction

This chapter is designed to provide the A/E with civil engineering criteria for site design at Job Corps Centers. Grading, utilities, site improvements and landscaping are covered as well as environmental considerations such as erosion control, storm water management, and wetlands.

2.1.1 Goal of Design Criteria

Assure an effective site design that meets DOL/Job Corps needs.

2.1.2 Applicable Codes

All civil/sitework shall conform to the applicable portions of the following codes:

• NFPA 101 Life Safety Code

• International Building Code

• Americans with Disabilities Act - Accessibility Guidelines for Buildings and

Facilities (ADAAG), and Uniform Federal Accessibility Standards (UFAS)

• ASCE Manual on Engineering Practice No. 37, Design of Storm and Sanitary

Sewers

• NFPA 13, Installation of Sprinkler Systems

• NFPA 24, Private Fire Service Mains

• NFPA 1141, Fire Protection in Planned Building Groups

• ASME B31.8, Gas Transmission and Distribution Piping Systems

• Clean Water Act (NPDES, Stormwater Management, and Wetlands)

• Clean Drinking Water Act

Although the Federal Government is not required to comply with local codes or obtain local permits for projects on Federal properties, DOL follows a “good neighbor policy” and meets the spirit of state and local codes and regulations to the extent possible. All variances from these requirements must be discussed with and approved by DOL. On leased facilities, compliance with prevailing local requirements is mandatory.

2-2

2.2 Existing Conditions

The A/E is responsible for providing complete and accurate information regarding the existing conditions of the site in accordance with the scope of services. Sufficient information must be provided for the construction contractor to furnish a “lump-sum” bid.

In order to enable the contractor to clearly identify the work items affected by his work, all significant surface features within the limits of work must be identified. Unless otherwise indicated, information regarding property lines, easements, rights-of-way, etc., will be furnished by DOL for inclusion in the plans by the A/E. It is not acceptable to require a site visit by the contractor to confirm the accuracy of the drawings. Complete and accurate drawings are the responsibility of the A/E.

All existing utility lines, including those underground, must be shown on the existing condition plans. Unless specifically tasked, DOL policy does not require excavation to locate buried utilities, tanks and other structures. The A/E is responsible for investigating accessible structures (manholes, vaults, etc.) and including information from readily available sources such as center, municipal and utility company documents. When complete/accurate information is unavailable and cannot be obtained with reasonable effort, the A/E must notify the DOL for additional direction. In all cases, indeterminate items should be indicated using best judgment, and should be noted as such.

When required by the Statement of Work (SOW), the A/E will furnish a topographic survey of the project site. This survey must be sufficiently detailed to allow accurate calculation of cut and fill quantities. Unless noted otherwise, a contour interval of not more than one foot is required. Spot elevations should be indicated sparingly for clarification and for significant features, not in place of contours.

When required by the SOW, the A/E will furnish a geotechnical investigation report of the project site. Sufficient testing must be provided to permit a rational design of pavements and other sitework.

In some cases, DOL requires specialized archeological testing by a contractor to determine whether archeological sites are present, and if so, to determine their extent, character and significance. If such testing is required, it should be coordinated with geotechnical testing to prevent inadvertent damage to archeological resources. The ESC Project Manager (ESC PM) will inform the A/E when archeological investigations may affect the project.

Drawings indicating existing conditions must be prepared in CADD format, using AIA layering conventions, and must be plotted at a scale that is clearly readable. Existing features and contours must be shown using dashed/shaded line types and line weights, which are distinguishable from new work. Features and contours should be clearly labeled.

Drawings that are cluttered are unacceptable.

2-3

Existing condition drawings must indicate recoverable benchmarks, both horizontal and vertical, adequate for the contractor to lay out the new work.

2.3 Demolition

Contract documents for site demolition items must be prepared to clearly indicate items to be removed and salvaged, and designate responsibility for protection of items and systems to remain. Items to be demolished in areas where new work is indicated or where work is proposed shall be completely removed and the site restored. In other locations, demolished items will be removed to a depth of at least three feet below the finished grade.

Responsibility for hauling and disposal, including all permits and dump fees, will reside with the contractor who must be required to provide evidence of compliance with all applicable regulations.

Where items are not completely demolished, i.e. pavements, sidewalks, utility lines, etc., the contractor will remove the work in a manner that provides a satisfactory joint for new construction. Utility lines will be removed to the nearest joint or fitting, and concrete/bituminous items will be removed to a joint or saw cut to a depth sufficient to provide a suitable joint.

It is the responsibility of the contractor to coordinate demolition with the applicable utilities and other authorities. The contractor must maintain services to those remaining structures, including water, electricity, fire alarms, and access. The contractor is also responsible for providing environmental protection during demolition operations, including but not limited to: dust and runoff control, litter control, street cleaning, tree and fire protection, and proper handling of environmental hazards such as asbestos.

Recycling and reuse of demolished materials is encouraged and should be addressed in the project documents whenever sufficient quantities make the approach practical.

For projects with limited demolition requirements and with approval of the ESC PM, a separate demolition plan will not be required, and the demolition items may be included on the existing conditions drawing. In all cases, the drawings must be clearly readable, and items called for demolition must be clearly indicated. Demolition will not be included on drawings that show new work, and removed items must not appear on those sheets.

2.4 Site Plans

The quality of the site design should be a direct extension of the building design and should make a positive contribution to the surrounding urban, suburban, or rural landscape.

Three characteristics usually distinguish Job Corps facilities: long life span, changing occupancies, and limited maintenance resources. DOL generally owns and operates its

2-4 facilities much longer than private sector owners. Accordingly, a higher level of durability is required for all systems, including site structures and underground utilities.

During the life span of a typical Job Corps Center, many minor and major alterations are necessary, as the missions of Government agencies and departments change. The site should be designed to accommodate periodic renovation activity by providing easy access with potential for staging areas.

2.4.1 Zoning Regulations

The Public Buildings Act Amendments of 1988 (U.S. Code Title 40, Chapter 12, Section

617) require that DOL consider local zoning and other planning requirements to the maximum extent practical. DOL follows a "good neighbor" policy of complying with local zoning ordinances and subdivision regulations. Regional DOL staff and A/E's must consult with local officials and provide them the opportunity to review the concept design of a new facility or an addition for zoning compliance. The comments must be treated as recommendations and carefully considered, however, DOL has the final authority to accept or reject any comment. Unless there is overriding reason to the contrary, DOL respects local restrictions on setbacks, height, massing, signage, and site design requirements. Landscape provisions in local ordinances should be viewed as a minimum requirement. In the case of leased facilities built on private land, all local zoning ordinances apply.

Local regulations must be followed without exception in the design of systems that have a direct impact on off-site terrain or utility systems, such as storm water run-off, erosion control, sanitary sewers, storm drains and water, gas, electrical power and other communications, emergency vehicle access, and roads and bridges.

2.4.2 Site Plan Approvals

Legally, buildings built on Federal property are exempt from local building/site planning codes. In cases of buildings developed on private land leased to DOL, however, the applicable local codes govern, and plans must be prepared in conformance with them. In this case, local jurisdictions have the option of performing construction inspections to verify code compliance. If they elect to do so, special provisions will be included in the A/E's and contractor's contracts to handle the additional requirement of coordinating their work with local authorities.

2.4.3 Existing Natural Features

Existing natural features on the site should generally be preserved and used as a starting point for the overall site design. Efforts should be made to preserve healthy trees, particularly if they are mature specimens.

2.4.4 Drawings

The site plan drawing(s) must clearly indicate the new construction on the site with all pertinent features such as curbs, sidewalks, and retaining walls. Do not show items for demolition on the site plan sheet. For most projects, a separate utility plan will be required, but utilities may be included on the site plan for small sites with limited utility work, with the approval of the ESC PM.

The site plan drawing must provide complete layout information for the contractor. This must include recoverable benchmarks, both vertical and horizontal, and dimensions. It is not acceptable to merely require that the contractor “stake out the work subject to the owner’s approval.” New buildings and structures must be located at two corners. Major street additions must have centerline layout information. Ball fields, parking areas, fences, and other items must be located (preferably by coordinates or otherwise by offsets) sufficiently for construction stakeout.

The site plan must clearly indicate the limits of work, contractor’s lay-down and storage area, and the site access restrictions. Where project phasing is required, the individual phases may be shown on the site plan, unless clarity requires a separate phasing plan.

2.5 Grading/Erosion and Sediment Control

2.5.1 Grading

Grading plans must indicate existing and proposed contours. These must be clearly differentiated by line type and weight. In addition to contours, plans must indicate finish floor elevations, spot elevations at all exits, bottom elevations in sumps, and top elevations at mounds.

Grading and earthwork requirements must reflect the geotechnical report. Information on soil types, moisture content, rock, etc., must be available to the contractor as a basis-of-bid.

The report must be included in the construction documents. Inclusion by reference is unacceptable.

New grading designs must maintain positive drainage (at least five percent) away from all structures for a distance of at least 10 feet, unless otherwise approved. Slopes will generally be limited to 33 percent (1:3) to allow for mowing by power equipment. Sidewalks and walkways must be graded to meet ADA requirements as applicable (in general, slopes not to exceed five percent). The minimum slope for grass swales and drainage ways is one percent, to prevent standing water and muddy conditions.

The high water level from the 100-year storm must be six inches below the finish floor elevation of new buildings. The A/E must demonstrate that this requirement has been met (by reference to the applicable FEMA flood insurance rate map, or other means). If this

2-6 requirement is not feasible, the ESC PM must be notified immediately. Unless otherwise approved, buildings must be protected against flooding by overland relief.

Paved areas must be adequately graded to provide positive drainage (typically one percent, minimum) and to prevent the discharge of concentrated runoff across intersections and walkways.

2.5.2 Erosion and Sediment Control

Erosion and sediment control measures must be designed by the A/E in conformance with local standards, and indicated on the drawings. It is not acceptable to merely indicate that, “contractor will provide erosion and sediment control in accordance with . . .” As a minimum, measures must be taken to prevent sediment from leaving the area defined under the limits of work, and from entering drainage structures or muddying streets. Details for elements such as erosion fencing, check dams, straw bale inlet protection, etc., may refer to state or local standards, but they must cite a specific detail in the standard. It is unacceptable to merely state that, “details will conform to . . .”

Special care must be taken to address construction specific items, such as temporary stockpiles and dust control. These elements may not appear on the drawings as part of the existing or final grading, but adequate erosion controls must be specified for inclusion in the contractor’s bid price.

2.6 Utilities

The A/E is expected to contact the local utility companies to coordinate service to DOL, proposed rate structures, rebates, system capacity, connection fees, permits, licenses, etc.

DOL will negotiate agreements with the utility companies as needed to amend rates and connection charges.

Complete and detailed construction documents must be provided for all utility systems. It is the A/E’s responsibility to design adequate utility services. This includes confirmation of adequate capacity at the points of connection. The plans must show size, length, slope, material, class, invert and top elevations for proposed lines and appurtenances.

Ownership of the individual utility systems varies from center to center. For those systems that are not the property of DOL, the design must conform to the requirements of, and be approved by, the utility owner.

All underground utilities must be marked with color-coded plastic warning tape containing metallic thread.

Provide protection for all ground mounted mechanical and electrical equipment from vehicular traffic. Limit access to all mechanical equipment with minimum 6' high fencing.

2.6.1 Storm and Sanitary Sewer Systems

Design of storm and sanitary sewers will be in accordance with ASCE Manual on Engineering Practice No. 37, Design of Storm and Sanitary Sewers. Designs must also be prepared to address the operational conditions of most Job Corps centers: a limited ability to conduct routine maintenance, and abuse of the systems by students. Lines and appurtenances can be expected to receive larger quantities of rags, grease, and other undesirable materials than normal, and may be subject to vandalism. For this reason, building sanitary sewer mains and service laterals must be a minimum of six inches in diameter, and storm sewers and culverts must be a minimum of 12 inches in diameter. Pipe materials should be selected for long service life with minimal maintenance, and pipe slopes should provide self-cleaning velocities at less than optimum flows.

Existing and proposed storm drain manholes, end walls, end sections, upstream and downstream ends of culverts and other storm structures, sanitary sewer manholes and structures on the plan, and profile drawings should be numbered.

Center storm sewers and appurtenances will be designed to convey the runoff from a 10-year storm. For larger sites and sites with multiple drainage areas, a drainage area map must be included in the plans, with boundaries superimposed on the grading plan showing sub-areas for each drainage inlet or structure, with runoff coefficient and area values for each sub-area.

It must show existing and proposed storm drains, channels, and structures with structure numbers. Offsite drainage sub-areas must be shown similarly, using the best available city, county, or USGS 1: 24,000 scale…
