Introduction The 2009 North Carolina Building Code includes requirements for the design and construction of retaining walls. Specifically, Section 1806.2 states: Retaining systems providing a cumulative vertical relief greater than 5 feet in height within a horizontal distance of 50 feet or less, including retaining walls or mechanically stabilized earth walls, shall be designed under the responsible charge of the registered design professional. Retaining systems shall meet the requirements of Section 1610. Testing and inspection reports shall comply with Section 1704.1.2 and shall verify: 1. Foundation support system is adequate for the intended site conditions; 2. Measurement of the quantity of construction materials for conformance with specifications; 3. Determination of similarity of actual soil conditions to those anticipated in design; and 4. Examination of backfill materials and any drainage systems for compliance with plans and specifications. Scope of Requirements These requirements will apply to all commercial construction, which include retaining walls and grades falling within the criteria described in Section 1806.2. In addition, the Town will apply the criteria to residential projects where retaining walls impact public use or access areas. Design and submittal requirements: Option 1: Submit, as part of the site plan review drawing set, retaining wall drawings, fully designed and detailed, and sealed by a North Carolina Licensed Professional Engineer. Option 2: Site plan review drawing set to include location and design criteria (wall height and schematic wall cross section) for retaining walls only, along with the following statements: • “Design of all retaining walls is to be per North Carolina Building Code Section 1806.” • “Detailed retaining wall design drawings, sealed by a North Carolina Licensed Professional Engineer, will be submitted to the Town prior to construction.” • “A North Carolina Licensed Professional Engineer must perform construction observation, verifying in a sealed letter to the Town that retaining walls are constructed per the engineered drawings.” Construction Requirements Construction of retaining walls may proceed only after detailed retaining wall design drawings, sealed by a North Carolina Licensed Professional Engineer, are submitted to the Town. The Owner’s North Carolina Licensed Professional Engineer will perform construction observation. Upon completion of retaining wall construction, the Engineer will submit 1) a sealed letter to the Town, verifying the retaining walls are constructed per the engineered drawings, in compliance with Section 1806 of the NC Building Code, and 2) a copy of all special inspections reports in accordance with Section 1704.1.3 of the NC Building Code. Certificates of Occupancy will only be issued after receipt of the Engineer’s sealed letter and copy of the special inspections reports.
The following embankment specifications apply to all stormwater and water quality facilities with embankments that are designed to hold water, even if the embankment is designed to hold water only during a storm event: Fill Materials The following parameters apply to materials used to construct earthen embankments: Borrow material shall be classified as ML, MH, SC, SM, CL or CH soils according to the Unified Soil Classification System (ASTM D2487) or any mixture of these soils. Borrow materials shall have a liquid limit (LL) between 40 and 60 and a plasticity index (PI) between 15 and 30 (ASTM D4318). Materials shall be free of topsoil, organic or frozen material, roots, stumps, brush, rocks larger than 3.0”, subsoil, debris, vegetation, and other foreign matter. All material clods will be broken down with tillers and/or discs to provide a homogeneous soil that is free of clay clods greater than 3.0” in diameter. Construction The following steps apply to construction of an earthen embankment:
Allowable Variances Earthen embankment specifications may be modified based on site-specific geotechnical investigation and engineering design. References

(The Ten Percent Rule)
Introduction The ten-percent rule recognizes the fact that a structural control providing detention has a “zone of influence” downstream where its effectiveness can be observed. Beyond this zone of influence the structural control becomes relatively small and insignificant compared to the runoff from the total drainage area at that point. Based on studies and master planning results for a large number of sites, that zone of influence is considered to be the point where the drainage area controlled by the detention facility comprises 10% of the total drainage area. For example, if the structural control drains 10 acres, the zone of influence ends at the point where the total drainage area is 100 acres or greater. Prior to initiating a downstream impact analysis, a scoping meeting must be coordinated with the Engineering Department to develop an understanding regarding the modeling software, design criteria, limits of the study, acceptable assumptions, report format, and required deliverables. These studies are intended to be used to determine the impacts that the increase of stormwater runoff creates from the site through the zone of influence. General Requirements

Introduction The 2009 North Carolina Building Code includes requirements for the design and construction of retaining walls. Specifically, Section 1806.2 states: Retaining systems providing a cumulative vertical relief greater than 5 feet in height within a horizontal distance of 50 feet or less, including retaining walls or mechanically stabilized earth walls, shall be designed under the responsible charge of the registered design professional. Retaining systems shall meet the requirements of Section 1610. Testing and inspection reports shall comply with Section 1704.1.2 and shall verify: 1. Foundation support system is adequate for the intended site conditions; 2. Measurement of the quantity of construction materials for conformance with specifications; 3. Determination of similarity of actual soil conditions to those anticipated in design; and 4. Examination of backfill materials and any drainage systems for compliance with plans and specifications. Scope of Requirements These requirements will apply to all commercial construction, which include retaining walls and grades falling within the criteria described in Section 1806.2. In addition, the Town will apply the criteria to residential projects where retaining walls impact public use or access areas. Design and submittal requirements: Option 1: Submit, as part of the site plan review drawing set, retaining wall drawings, fully designed and detailed, and sealed by a North Carolina Licensed Professional Engineer. Option 2: Site plan review drawing set to include location and design criteria (wall height and schematic wall cross section) for retaining walls only, along with the following statements: • “Design of all retaining walls is to be per North Carolina Building Code Section 1806.” • “Detailed retaining wall design drawings, sealed by a North Carolina Licensed Professional Engineer, will be submitted to the Town prior to construction.” • “A North Carolina Licensed Professional Engineer must perform construction observation, verifying in a sealed letter to the Town that retaining walls are constructed per the engineered drawings.” Construction Requirements Construction of retaining walls may proceed only after detailed retaining wall design drawings, sealed by a North Carolina Licensed Professional Engineer, are submitted to the Town. The Owner’s North Carolina Licensed Professional Engineer will perform construction observation. Upon completion of retaining wall construction, the Engineer will submit 1) a sealed letter to the Town, verifying the retaining walls are constructed per the engineered drawings, in compliance with Section 1806 of the NC Building Code, and 2) a copy of all special inspections reports in accordance with Section 1704.1.3 of the NC Building Code. Certificates of Occupancy will only be issued after receipt of the Engineer’s sealed letter and copy of the special inspections reports.
The following embankment specifications apply to all stormwater and water quality facilities with embankments that are designed to hold water, even if the embankment is designed to hold water only during a storm event: Fill Materials The following parameters apply to materials used to construct earthen embankments: Borrow material shall be classified as ML, MH, SC, SM, CL or CH soils according to the Unified Soil Classification System (ASTM D2487) or any mixture of these soils. Borrow materials shall have a liquid limit (LL) between 40 and 60 and a plasticity index (PI) between 15 and 30 (ASTM D4318). Materials shall be free of topsoil, organic or frozen material, roots, stumps, brush, rocks larger than 3.0”, subsoil, debris, vegetation, and other foreign matter. All material clods will be broken down with tillers and/or discs to provide a homogeneous soil that is free of clay clods greater than 3.0” in diameter. Construction The following steps apply to construction of an earthen embankment:
Allowable Variances Earthen embankment specifications may be modified based on site-specific geotechnical investigation and engineering design. References

(The Ten Percent Rule)
Introduction The ten-percent rule recognizes the fact that a structural control providing detention has a “zone of influence” downstream where its effectiveness can be observed. Beyond this zone of influence the structural control becomes relatively small and insignificant compared to the runoff from the total drainage area at that point. Based on studies and master planning results for a large number of sites, that zone of influence is considered to be the point where the drainage area controlled by the detention facility comprises 10% of the total drainage area. For example, if the structural control drains 10 acres, the zone of influence ends at the point where the total drainage area is 100 acres or greater. Prior to initiating a downstream impact analysis, a scoping meeting must be coordinated with the Engineering Department to develop an understanding regarding the modeling software, design criteria, limits of the study, acceptable assumptions, report format, and required deliverables. These studies are intended to be used to determine the impacts that the increase of stormwater runoff creates from the site through the zone of influence. General Requirements
