5-8 Special design considerations This section is specifically included to provide guidance for development of properties which may not have access to centralized or approved community sewer facilities. Since some of the planning area is not served by sewer, the criteria set forth herein will have significant impact on subdividing and development of properties particularly for residential purposes. The guidelines and requirements have been established by the Arkansas State Health Department.

Certification by the engineer that all percolation tests and soil borings were done in accordance with Arkansas State Department of Health Bulletin No. 9.
B. If the use of a public water supply is proposed and individual septic tankabsorption field systems are to be used for sewage disposal, the following criteria is required: 1. Lot size should be a minimum of 21,780 sq. ft., but is not mandatory, in accordance with Bulletin No. 9 of the Arkansas State Department of Health. 2. The lot width and size requirements may be varied in areas where percolation rates and subsurface conditions permit and approval of the Arkansas State Department of Health is obtained. 3. The septic tank-absorption field system must be constructed in accordance with Bulletin No. 9 of the Arkansas State Department of Health. The above criteria also apply to building sites not located within subdivision areas. (Ord. No. 04-4, Art. 5.)
15.04.06 Required improvements
6-1 Required improvements
No final plat shall be approved by the Planning Commission until the following improvements have been installed by the applicant, subject to alternatives specified in 15.04.06, and approved by appropriate city, county and state agencies, utilities and the Planning Commission.

B. Place test head of vacuum tester at inside top of manhole rim and inflate seal in accordance with manufacturer’s recommendations.
C. Connect vacuum pump to outlet port on test head with valve open.
D. Draw vacuum of ten (10) inches of mercury (HG), close valve, and shut off vacuum pump.

H. Retest using same procedure until manhole passes test.
6-5 Where lots cannot be economically connected to the public gravity sewer system, they must contain adequate area for the installation of an approved septic system, reference 15.04.05, or install an individual residential pump station. Plans for water and sewer systems must be sent to The Arkansas Department of Health at 4815 West Markham in Little Rock, Arkansas 72205 for approval. A review fee must be attached. The fee is one (1) percent of the total cost of construction, or Fifty Dollars ($50.00) whichever is the greater amount.

Sub-drainage shall be constructed in accordance with AHTD details and specifications when applicable.
6-14 Street paving Streets shall be paved by the developer to the widths and standards specified and adopted by the city of Clinton. Once the requirements of 6-13 are complete and before the base course is put down, the developer must insure that all utilities that must be laid under the street are in place at proper spacing and depth, or empty pipe sleeves may be installed. All utilities should be installed in lot easements when possible and not in street right-of-ways. A. Base course Base course shall be Class 7 aggregate material as defined by the Arkansas Highway and Transportation Department (AHTD) or an alternate material approved by the city or city’s engineer.

Use medium curing liquid asphalt, MC-30, or approved equal, meeting AHTD specifications. C. Asphalt binder course Type 2 asphalt concrete hot mix binder as described in AHTD specifications. Asphalt shall not be laid if its ambient temperature is less than 250 des. F. ADTD specifications shall apply to material, construction and quality control procedures. D. Tack coat Apply bituminous tack coat to binder asphalt course at the rate of 0.03 to 0.10 gallons per square yard. Use rapid curing cut-back asphalt or emulsified asphalt meeting AHTD specifications. E. Asphalt surface course Type 2 asphalt concrete hot mix surface as described in AHTD specifications shall apply to material, construction and quality control procedures. Areas that pond ¼ ” or more water or that otherwise do not drain properly will be rejected and shall be removed full depth and properly replaced. F. Concrete streets Concrete streets shall be designed by a professional engineer licensed in the state of Arkansas. They must meet the design and construction requirements of AHTD.
6-15 Curbs and gutters Concrete curb and gutter shall be required along both sides of all proposed roadways. The subgrade underneath the curb and gutter shall be compacted to no less than 95% modified proctor – ASTM D 1557.

Face of curb shall be rounded ot approximately 1″ radius. concrete shall be 3,000 PSE (28 Day) Portland cement concrete with a light broom finish. Construct ½ ” elastic water proof premolded expansion joint fillers at no greater than 60′ intervals, at curb returns and at intersections with other abutting structures. Concrete shall be consolidated using a mechanical vibrator. contraction joints shall be placed at 10′ intervals. The gutter profile shall be no less than 0.50% and preferably 1.00% or greater. Open shoulders (without curb and gutter) are not allowed, except by approved variance or waiver.

The subgrade underneath the sidewalk shall be compacted to no less than 955 modified proctor – ASTM D1557. Construct ½ ” premolded expansion joint fillers at no greater than 28′ intervals, at intersections with curbs, other sidewalks, and at intersections with other abutting structures. also place expansion joints where pour is stopped when other than at a scheduled expansion joint. Expansion joints shall be sealed. Cut control joints at 4′ intervals, ½ “depth with a jointing tool having a ¼ ” radius on each side. All sidewalks shall conform to the Americans with Disabilities Act (ADA). Cross slopes shall not in any case exceed 2%, and sidewalk profile shall not exceed 1:12, or 1:20 with landing, all in accordance with ADA requiremens. Steps in public right-ofway are normally not allowed and considered on a case-by-case basis. Handicap ramps shall be no less than 4′ wide (excluding sloping side wings) and to the same thickness and concrete specifications as sidewalks. In addition, they will receive a light broom finish and shall have sawcut grooves or joints troweled into the surface at 4″ center to center and running perpendicular to the walkway, and the profile slope shall not exceed 1:12 (one inch in 12″ of run). Ramps shall be positioned to direct the pedestrian in a direction that is perpendicular to the traffic.
6-17 Temporary and permanent erosion control Developers are required to provide a temporary erosion control plan as part of their submitted construction documents.

The use of silt fencing, hay bales, rock check dams and other erosion control devices, as may be applicable, shall be implemented immediately, which normally would follow clearing operations, and prior to excavating. Erosion control devices must be cleaned and maintained periodically for the direction of the project or until permanent erosion control features have been fully constructed, and have become functional. Permanent erosion control features may include hydorseeding, seeding, mulching, sodding, rock ditch checks and rip rap among other options. In addition, all disturbed areas shall receive no less than four (4) inches select topsoil and be seeded and mulched in accordance with AHTD specifications.
6-18 Clearing and burning or disposal Clearing shall not be performed prior to obtaining a permit. Burning may or may not be allowed within the city, and will be determined based on location, amount and type of material to be burned, meterological conditions and proper procurement of permitting. Whenever a burn ban is in effect, no burning will be allowed under any circumstances. When burning is permitted, only organic materials may be burned and shall be performed under the continual care of a competent watchperson with adequate means to control the spreading of fire. In no case shall burning cause smoke to obscure the vision of any motorists on public roadways or be allowed to saturate inhabited areas, or otherwise become a nuisance to the public. When trees, debris and other materials are disposed of at an off-site location, the developer shall obtain written approval from the disposal site owner, and the disposal site shall be a legally operated facility.
