It is the intent of this chapter to protect, maintain, and enhance the health, safety, and general welfare of the citizens of the City of Fayetteville by: (1) Preventing increases in the magnitude and frequency of stormwater runoff to prevent increases in flood flows and associated hazards and costs. (2) Controlling soil erosion and sedimentation to minimize soil deposition in streams and other receiving water bodies and storm drainage systems. (3) Requiring surface and stormwater management practices that comply with requirements of this chapter. (4) Promoting the development of stormwater facilities that are aesthetically desirable. (B) Findings of fact. The City Council finds that uncontrolled stormwater runoff from developed land adversely affects the public health, safety, and welfare because: (1) Impervious surfaces / runoff. Impervious surfaces increase the quantity and velocity of surface runoff, which reduces percolation of water through soil and increases erosion and flooding. (2) Collection and conveyance of storm water. Improper stormwater collection and conveyance adversely affects property and increases the incidence and severity of flooding, which can endanger property and human life. (3) Erosion. Increased erosion leads to sedimentation in stormwater management systems, which decreases the system's capacity (4) Future problems. Many future problems can be avoided if land is developed in accordance with sound stormwater runoff management practices. (Code 1991, §163.03; Ord. No. 3895, 1, 6-20-95; Ord. No. 4100, §2 (Ex. A), 6-16-98; Ord. No. 4855, 4-18-06; Ord. 4920, 9-05-06) CD170:3 170.02 Adoption Of Drainage Criteria Manual The City Council hereby adopts by reference the Drainage Criteria Manual, prepared for the City of Fayetteville, and adopted by Ordinance No. 3895 of the City of Fayetteville, and as may be amended from time to time. All technical procedures and design standards contained therein shall have the same force and effect as if printed word for word in this chapter. (Code 1991, §163.03; Ord. No. 3895, §1, 6-20-95; Ord. No. 4100, §2 (Ex. A), 6-16-98; Ord. 4920, 09-05-06) 170.03 Permits Required (A) Applicability. This chapter shall apply to all land within the corporate limits of the City of Fayetteville. No person may subdivide and develop, change to a more intensive land use, construct or reconstruct a structure, or change the size of a structure, or conduct grading, clearing, or filling activities without first obtaining a stormwater management, drainage and erosion control permit (hereinafter referred to as a "drainage permit") from the city, except as specified in §170.03(C) and §170.03 (D) below. (B) Permit application. Any application for a drainage permit shall be submitted according to §170.05 below, and shall be submitted concurrently with the application for a grading permit, if such grading permit is required by § 169.03. The drainage permit applications shall include at the time of submission the calculations required by §170.05(B)(7). The application also shall state whether or not detention is required, and shall provide the basis for that conclusion, utilizing the performance criteria set forth in §170.07 below. The City Engineer shall make the final determination regarding detention. (C) Project not requiring detention. Any project that requires a drainage permit that does not require detention may receive, with the approval of the City Engineer, a grading permit prior to issuance of the drainage permit. Any grading permit issued prior to the issuance of a required drainage permit shall be subject to the following: (1) Insufficient or incomplete drainage permit application. If the drainage permit application, including the required calculations, is determined by the City Engineer to be insufficient or incomplete, it shall be revised and resubmitted by the applicant within four (4) weeks of receipt of Exhibit "B" written notice of insufficiency or incompleteness. (2) Deadline for the revised application. A stop work order for all grading on the project shall be issued by the City Engineer if a revised application is not submitted within four (4) weeks of receipt by applicant of the written notice of insufficiency or incompleteness. However, the City Engineer may delay issuance of the stop work order if the City Engineer determines that the applicant has demonstrated prior to the deadline that circumstances not reasonably foreseeable and beyond the applicant's reasonable control prevented his timely resubmission of a sufficient and complete revised drainage permit application. (3) Insufficient or incomplete revised application. A stop work order for all grading on the project shall be issued by the City Engineer if the revised application is determined by the City Engineer to be still insufficient or incomplete. (4) Stabilization and revegetation after stop work order. If a stop work order is issued pursuant to §170.03 (C) (3), the applicant shall stabilize and revegetate all graded and otherwise disturbed areas as set forth in §169.06(F)(6) and §169.04(B). (5) Termination of stop work order. Any stop work order issued pursuant to §170.03 (C) (2) or §170.03 (C) (3), shall expire upon the issuance of a drainage permit and compliance with any conditions contained in the drainage permit. (D) Exceptions where no drainage permit is required. Drainage permits are not required for the following: (1) Single-family/duplex. One single-family residence or duplex. A drainage permit is not required. See Section 170.12 for building permit submittal requirements. (2) Commercial/Industrial. One commercial or industrial project built on an individual lot that is part of a larger subdivision that has been issued an approved drainage control permit when the proposed project is demonstrated to be in compliance with the overall subdivision drainage permit. (3) Existing commercial/Industrial. Existing commercial and industrial structure where additional structural improvements are less than 2,000 square feet. (4) Maintenance. Maintenance or clearing activity that does not change or affect the quality, rate, volume, or location of stormwater flows on the site, or runoff from the site. (5) Agriculture. Bona fide agricultural pursuits, for which a soil conservation plan has been approved by the local Soil and Water Conservation District. (6) Emergency. Action taken under emergency conditions, either to prevent imminent harm or danger to persons, or to protect property from imminent danger of fire, violent storms, or other hazards. (E) Compliance with chapter provisions. Although a specific permit is not required for these particular circumstances, this exception does not exempt the owner/developer/builder from complying with the pollution prevention and erosion and sediment control provisions of this chapter.

The Proposed code changes will clarify stabilization requirements, require phased construction for sites larger than 20 acres, clarify re -vegetation requirements, clarify requirements for cut and fill slopes and retaining walls, define maintenance responsibility for stormwater management systems, restrict the location of dirt and topsoil storage and define stabilization practices for dirt and topsoil storage, define a qualified inspector for erosion and sediment control BMPs, and require site plans for 1&2 family residences to contain a plan for erosion and sediment control and final on -site drainage. A summary of the major points of revision for each chapter is attached along with the complete revised ordinance. The proposed revisions are driven by the following four objectives: • The Nutrient Reduction Plan, completed by the City based on the 2006 Agreement between the City and Beaver Water District, recommended certain revisions to Chapter 169 and 170 of the UDC. • The City's Arkansas Department of Environmental Quality NPDES General Permit No. ARR040000 requires the City to be as strict as or stricter than the requirements of the Arkansas Department of Environmental Quality NPDES General Permit No. ARR150000 — Construction General Permit. • The City's Arkansas Department of Environmental Quality NPDES General Permit No. ARR040000 requires post -construction stormwater management to minimize water quality impacts and ensure the long-term operation and maintenance of selected Best Management Practices. • Staff seeks to address and plan for the drainage of residential lots before homes are constructed. Repairs to alleviate drainage problems can be costly to both the City and home owner. These ordinance revisions were reviewed by the Planning Commission on May 10, 2010. The Planning Commission forwarded ADM 10-3571 to City Council with a recommendation for approval. Planning Commission meeting minutes are attached. In addition to review by the Planning Commission, the proposed revisions were posted on the City's website and were sent by email to Planning's development community THE CITY OF FAYETTEVILLE, ARKANSAS email list. No comments were received from the public or development community in response to the web posting or email. RECOMMENDATION Staff and Planning Commission recommend approval of revisions to UDC Chapter 169 Physical Alteration of Land and Chapter 170 Stormwater Management, Drainage and Erosion Control. BUDGET IMPACT The proposed ordinance amendments will cause no budget impact.

The proposed code changes will clarify stabilization requirements, require phased construction for sites larger than 20 acres, clarify re -vegetation requirements, clarify requirements for cut and fill slopes and retaining walls, define maintenance responsibility for stormwater management systems, restrict the location of dirt and topsoil storage and define stabilization practices for dirt and topsoil storage, define a qualified inspector for erosion and sediment control BMPs, and require site plans for 1- and 2 -family residences to contain a plan for erosion and sediment control and final on -site drainage. Sarah Wrede, Floodplain Administrator gave the staff report. Public comment Brian Teague, Community by Design, believes that the ordinance will work hand in hand with the recently adopted LID and promotes compact urban design envisioned by City Plan 2025. Garland Hill asked why the ordinance is limited to 20 acres or larger. Commissioner Cabe asked staff to address Mr. Hill's question Glenn Newman, staff engineer, explained that the recommended size is related to sequencing phases. Commissioner Hoskins and Newman discussed the issue and history of rear lot drainage for clarification and the issue of sediment in the street. Commissioner Hoskins stated that he does not support holding smaller development to the same standards as large developments. Commissioner Chesser stated that the larger developments are held to a higher standard than the smaller developments and does not agree that they should be held to different standards. Commissioner Cabe asked for clarification of the differences between the existing requirements and the new requirements. Wrede explained that the code is intended to clarify the approved method of debris removal from the street in order to prevent sedimentary materials from reaching streams and that ADEQ regulate single-family construction when the lot is part of a larger development plan. Commissioner Chesser and Newman discussed single-family residential safety railing requirements for clarification. Motion: Commissioner Kennedy made a motion to forward the item to the City Council with a recommendation of approval. Commissioner Chesser seconded the motion. Upon roll call the motion to forward was approved with a vote of 6-1-0 with Commissioner Hoskins voting "no." THE CITY OF FAYETTEVILLE, ARKANSAS ENGINEERING DIVISION 125 West Mountain Fayetteville, AR 72701 Phone (479)444-3443 TO: Fayetteville City Council, meeting of July 6, 2010 FROM: Sarah Wrede, Staff Engineer THRU: Jeremy Pate, Development Services Director Chris Brown, City Engineer DATE: May 4, 2010 RE: Summary of Proposed Revisions to CHAPTER 169: PHYSICAL ALTERATION OF LAND Staff is proposing revisions throughout CHAPTER 169: PHYSICAL ALTERATION OF LAND. Please view the draft ordinance for complete revisions. The retaining wall diagrams on pages 9 and 10 have been completely revised. The major points of revision to CHAPTER 169: PHYSICAL ALTERATION OF LAND are summarized below: Stabilization 169.04 Minimal Erosion Control Requirements, Section B • Existing to Remove: Stabilization. All graded and otherwise disturbed areas shall be stabilized within 15 days immediately after the grading or disturbance has been completed. Stabilization methods such as baled straw, filter fabric, ditch checks, diversion ditches, brush barriers, sediment basins, matting, mulches, grasses and groundcover shall be used. Replace With: A record of the dates when grading activities occur, when construction activities temporarily or permanently cease on a portion of the site, and when stabilization measures are initiated shall be included in the erosion and sediment control plan. Except as provided in (1) and (2) below, stabilization measures shall be initiated as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased. (1) Where the initiation of stabilization measures by the 14th day after construction activity temporarily or permanently ceases is precluded by snow cover, stabilization measures shall be initiated as soon as practicable. (2) Where construction activity will resume on a portion of the site within 21 days from when activities ceased, (e.g. the total time period that construction activity is temporarily ceased is less than 21 days) then stabilization measures do not have to be initiated on that portion of the site by the 14`h day after construction activity temporarily ceased Stabilization practices may include: temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative buffer strips, protection of trees, and preservation of mature vegetation and other appropriate measures. Reasons for revision: This is a recommendation from the Nutrient Reduction Plan and it conforms to the Arkansas Department of Environmental Quality NPDES General Permit No. ARRI 50000 — Construction General Permit. The "record of dates" will also allow the City's inspectors to more effectively enforce these requirements. Debris, mud, and soil in public streets • 169.04 Minimal Erosion Control Requirements, Section (F) • Existing to Remove: Removal of mud/dirt from public streets. Any debris, soil, or mud from development sites reaching a public street shall be immediately removed. Telecommunications Device for the Deaf TOO (479) 521-1316 113 West Mountain - Fayetteville, AR 72701 THE CITY OF FAYETTEVILLE, ARKANSAS • Replace With: Debris, mud, and soil in public streets. Debris, mud and soil shall not be allowed on public streets but if any debris, mud, or soil from development sites reaches the public street it shall be immediately removed via sweeping or other methods of physical removal. Debris, mud, or soil in the street may not be washed off the street or washed into the storm drainage system. Storm drainage systems downstream of a development site should be protected from debris, mud, or soil in the event that debris, mud, or soil reaches the drainage system. • Reasons for revision: This revision expands and clarifies the City's requirements to comply with the Arkansas Department of Environmental Quality NPDES General Permit No. ARR1 50000 — Construction General Permit. Phased Construction • 169.06 Land Alteration Requirements, Section (F) (2) • New Language: Phased Construction. The area of disturbance onsite at any one time shall be limited to 20 acres. An additional 20 acres (a maximum of 40 acres of disturbance at any one time) may be stripped with the permission of the City Engineer in order to balance cut and fill onsite. No additional area may be open without the permission of the City Engineer until the previously disturbed areas have been temporarily or permanently stabilized. • Reasons for revision: This is a recommendation from the Nutrient Reduction Plan. This is not currently an ADEQ Construction General Permit requirement. Ton Soil • 169.06 Land Alteration Requirements, Section (F) (3 and 5) • Existing to Remove: Top soil. Top soil shall be stockpiled and protected for later use on areas requiring landscaping. If top soil or other soil is to be stockpiled for more than 30 days, a temporary cover of annual rye or other suitable grass shall be planted. Replace With: Stockpiling of top soil. Top soil shall be stockpiled and protected for later use on areas requiring landscaping. All storage piles of soil, dirt or other building materials (e.g. sand) shall be located more than 25 feet from a roadway, drainage channel or stream (from top of bank), wetland, and stormwater facility. The City Engineer may also require top soil stockpiles to be located up to fifty (50) feet from a drainage channel or stream, as measured from the top of the bank to the stockpile, for established TMDL water bodies; streams listed on the State 303(d) list; an Extraordinary Resource Water, Ecologically Sensitive Waterbody, and/or Natural and Scenic Waterbody, as defined by Arkansas Pollution Control and Ecology Commission Regulation No. 2; and/or any other uses at the discretion of the City Engineer. Topsoil piles surfaces must be immediately stabilized with appropriate stabilization measures. Stabilization practices may include: temporary seeding (i.e. annual rye or other suitable grass), mulching, and other appropriate measures. Sediment control measures such as silt fence shall be provided immediately for stockpiles and remain in place until other stabilization is in place. Storm drain inlets must be protected from potential sedimentation from storage piles by silt fence or other appropriate barriers. Re -vegetation. Re -vegetation shall be required to meet the following performance standards (sediment controls shall remain in place until re -vegetation is established) unless otherwise allowed by the City Engineer: (a) Topsoil. A minimum of 4 inches of topsoil shall be required to be either existing or installed in areas to be re - vegetated. Any application of topsoil and seeding under the drip line of a tree should be minimized to 3 inches so as not to damage the trees root system. (b) Zero to 10% grade: Re -vegetation shall be a minimum of seeding and mulching. Said seeding shall provide complete and uniform coverage that minimizes erosion and runoff in no more than two growing seasons. Telecommunications Device for the Deaf TDD(479)521-1316 113 West Mountain -Fayetteville, AR 72701 THE CITY OF FAYETTEVILLE, ARKANSAS (c) 10:1 up to 4:1 grade: Re -vegetation shall be a minimum of hydro -seeding with mulch and fertilizer, sod, or groundcover. Said planting shall provide complete and uniform coverage in no more than two growing seasons. (d) 4:1 to 3:1 grade: The slope shall be covered with landscape fabric and hydro -seeded with mulch and fertilizer, or staked sod, or groundcover. Said planting shall provide complete and uniform coverage in no more than two growing seasons. (e) More than 3:1 grade: Any finish grade over 3: shall be stabilized with one or more of the following: 1) Retaining walls; 2) Cribbing with landscape fabric; 3) Terracing with groundcover; 4) Riprap; 5) Staked Sod (up to 2:1 slope) If Cribbing, Terracing, or Riprap is used, the slope's stability and erodibility must be equivalent to or better than its predevelopment state. • Reasons for revision: This is a recommendation from the Nutrient Reduction Plan and conforms with the Arkansas Department of Environmental Quality NPDES General Permit No. ARR150000 — Construction General Permit. The re -vegetation section is recommended by staff for clarification of existing policy. Preliminary Plat Master Build -Out Grading Plan • 169.07 Grading Plan Specifications, Section (A) (18) • New Language: Preliminary plat master build -out grading plan. The applicant shall prepare a master grading plan to be followed during individual lot development to convey runoff to a public drainage easement or right of way. In addition to the requirements of 169.07 A, the following shall be required for individual lot drainage design: a. Identify lot lines and conceptual foot print of residence. b. Establish the minimum finish floor and grading adjacent to the residential structure in accordance with Chapter 173 Building Regulations and the Arkansas Fire Prevention Code. c. Indicate individual lot drainage with the use of spot elevations and flow arrows. i. The minimum slope of the flow path from the top of curb, top bank, or approved drainage inlet to the high point of the final graded lot shall be at a minimum of 2% for grassed surfaces. ii. In general, drainage should be routed on the shortest practicable flow path to the public right of way or drainage easement. d. Non structural grassed swales for rear lot drainage concentration is discouraged and shall not be installed in combination with a utility easement. e. Utility Easements shall be graded and shaped in accordance with the master build -out grading plan during preliminary plat construction. i. Provisions will be considered to accommodate positive drainage until build -out occurs. • Reasons for revision: This section is recommended by staff in an effort to address and plan for the drainage of residential lots before homes are constructed after which repairs to alleviate drainage problems can be costly to both the City and home owner.

Please view the draft ordinance for complete revisions. The major points of revision to CHAPTER 170: STORMWATER MANAGEMENT, DRAINAGE AND EROSION CONTROL are summarized below: Low Impact Development • 170.07 Performance Criteria, Section (B) (3) • New Language: Low Impact Development. Use of Low Impact Development design strategies, as described in Chapter 179, to attenuate lesser storms and more closely mimic predevelopment hydrology is encouraged. Direct Discharge • 170.07 Performance Criteria, Section (B) (4) • New Language: Direct Discharge. Direct Discharge of a pipe into streams and/or floodways is not allowed. A stilling basin or other structure that will collect sediment, trash, etc and that will reduce the likelihood of erosion in the receiving stream due to discharge from the pipe shall be installed at pipe discharges into streams and/or floodways. • Reasons for revision: This Best Management Practice supports the City's Arkansas Department of Environmental Quality NPDES General Permit No. ARR040000, Post -Construction Stormwater Management goal to minimize water quality impacts. Maintenance Responsibility • 170.08 Maintenance Responsibility, Sections (A — G) • New Language: (A) Dedication. Those stormwater management systems approved in compliance with this chapter that will function as a part of the stormwater management conveyance system shall be dedicated to the city. All areas and/or structures to be dedicated to the city must be dedicated by plat or separate instrument and accepted by the City Engineer. (B) Perpetual Inspections and Maintenance Agreements. The City shall require a Stormwater Management Practices Maintenance Agreement, for systems not dedicated to the City, of all entities for stormwater management conveyance systems and structures in the stormwater management plan for their proposed development. The City shall require the following set of documents and agreements prior to stormwater systems and structures approval: (1) Agreement of Maintenance Responsibility. The owner of the property on which the stormwater systems structures have been installed shall agree to undergo ongoing inspections, and document maintenance and repair needs.
