4000 Site Selection and DesignSchool Districts shall comply with the site selectionrequirements of A.C.A. § 6-21-809(b)(3), as amendedby Act 858 of 2019.PurposeThe purpose of this chapter is to provide theSchool District and the Design Professional withinformative guidelines to consider prior toselection, purchase, and development of a site.DPSAFT has not established standards withrespect to site selection and design.Information is included for informationalpurposes only.Site Selection CriteriaAt first look, a potential site may appear tobe a good acquisition.There are manyfactors, however, that can distort the picture.A site may be reduced in size if wetlands thesite or if part of the area is in a floodplain.There should be a watershed nearby to allowfor adequate storm drainage.Irregulartopography can escalate site developmentcosts. Adequate area is needed to retain andrelease storm water from the site.Access to and from the site, from a majorhighway or road artery is an important factor.In addition to understanding surfacecharacteristics, sub-surface conditions mayrequire exploration. Preliminary soil boringsshould be considered to ascertain thepresence of poor soil, high water table, voids,orotherimpediments.APhaseIenvironmental study should be a requirement.Site DesignWith a good site available, site design andlayout becomes the next task. Good sitedesign includes separate bus and carcirculation, safe passage for students enteringor exiting buses, and bus parking arranged ina continuous line or a 45 degree parkingarrangement.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 20191

4000 Site Selection and DesignSite Design (continued)Visitor and staff parking and a separateservice drive is recommended.Orientation of the building is an importantfactor when considering energy usage. Amajority of the windows should be locatedon the north or south side of the building.Easy access to the main entrance should beobvious to all.Good site design requires careful andthorough planning to provide maximumsafety, and efficient utilization of sitefeatures.Site SizeThe recommended minimum site size foundin this section should be considered whenconsidering a new school site. The sizeguidelines are consistent with thoserecommended in the Council of EducationalFacility Planners International (CEFPI), Guidefor School Facility Appraisal.FencingSite design should incorporate adequatefencing for the safety of students. Fencingshould be considered along perimeters ofplaygrounds and play areas and in otherperimeter areas to prevent students fromwandering off of school property. Fencingshould be considered along vehicular trafficways to prevent students from accidentallyentering traffic.Fencing of potentially hazardous areas, suchas: railroad tracks, trash enclosures andcompactors, outdoor storage areas, stormwaterdetentionponds,electricaltransformers, mechanical equipment areas,etc., should also be considered.Fencing materials may vary widely, butshould be durable and low maintenance.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 20192

4000 Site Selection and DesignSite Size Arkansas Public School Academic Facility Manual - Chapter 4December 30, 2019Recommended minimum site sizesare: Elementary School: 10 acres plus1 acre per 100 students Middle School: 20 acres plus 1acre per 100 students High School: 35 acres plus 1 acreper 100 students Combination Schools: K-12 School: 40 acres plus 1acre per 100 students K-8 School: 20 acres plus 1acre per 100 studentsDeviationsfromrecommendedminimum site sizes may be neededbecauseofextenuatingcircumstances, especially in urbanareas.Larger site sizes or additionalacreage may be needed to allowadequate land for storm waterdetention,buildingexpansion,topography features, subsurfacesanitary sewage systems, etc.3

4000 Site Selection and DesignUrban Site SizeIt is recognized that not all sites,especially those found in urban areas,will be able to accommodate new orreplacement facilities. Therefore, itmay be necessary to modify/reduceareas such as parking and circulation to“fit” the facility on the smaller site. Alist of reductions to consider is providedto assist the School District and DesignProfessional in analyzing different sizeoptions. Decrease the amount of visitor andstaff parking to be provided Decrease the amount of studentparking provided Decrease the amount of mechanicalyard space to be provided Delete the bus drop-off and parentdrop-off areas and provide curbsideservice only Reduce the amount of greenspace tobe provided Reduce/decrease the size/numberof playfields/playgrounds to beprovidedArkansas Public School Academic Facility Manual - Chapter 4December 30, 20194

4000 Site Selection and DesignParking Arkansas Public School Academic Facility Manual - Chapter 4December 30, 2019The following chart is intended to assist in thedevelopment of the recommended parking for newfacilities.Provide the suggested number of accessible parkingspaces as indicated in the chart below.Confirm all parking quantities with local building,planning, and/or zoning departments.It is suggested that staff parking be located in asecured area separated from other facility parking.Check to see that the number of parking spacesequals or exceeds the requirements of the localgoverning agencies.5

4000 Site Selection and DesignOutdoor Athletic and Recreation Fields When selecting a site, considerationshould be given regarding the size andconfiguration of type and quantity ofoutdoor athletic and recreation fields tobe accommodated.The designer should consider drainage,circulation, access, and the need forbleacher seating when determining schoolsite sizes.Site DesignGeneralFollowing are additional factorsto consider when determining themerits of a potential site: Topography Vehicle Access Soil Characteristics Site Utilities Site Preparation Codes and Zoning Adjacent Property Easements/Rights-of-Way Environmental Restrictions Testing Aesthetic Considerations Vehicular Circulation Pedestrian Circulation Storm Sewer System Detention Pond Sanitary/Sewage Directional Signage Playgrounds Lighting Landscaping Positive DrainageArkansas Public School Academic Facility Manual - Chapter 4December 30, 20196

4000 Site Selection and DesignSchool Districts shall submit site selection(s) to theArkansas Department of Transportation (ARDOT) fortheir consideration of a traffic study per Act 858 of2019.Topography A reasonably level area is needed toaccommodate buildings, parking, studentplaygrounds, and physical education areas. There should be sufficient slope to allow forpositive drainage to storm sewer outlets orother discharge points. Retain natural features. Land whose elevation is lower than 5 feetabove the elevation of the 100 year flood asdefined by FEMA should not be considered fordevelopment.Vehicular Access A traffic study may be needed to predict theimpact of the school at peak times of arrivaland dismissal. Consult local street or highway departmentfor turn lane, drive widths, and radiusrequirements. Review site distances at proposed entry exitfor hazardous conditions. Two or three entry/exit points into the siteare recommended to provide appropriateseparation of car and bus traffic.Soil Characteristics Obtain preliminary soil borings to obtaincharacteristicsforfoundationdesign,pavement design, storm sewer design, andexcavation requirements. The presence of high ground water may resultin the need for an underground drainagesystem. Erosion characteristics may affect the needfor temporary measures, such as silt fence,etc.Site Utilities Storm water may need to be detained on siteand released at a rate that will not exceedcurrent runoff rates and meets requirementsof the authority having jurisdiction. Sewage from school buildings should bedischarged into an approved sewage systemper applicable codes.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 20197

4000 Site Selection and DesignSite Utilities – cont’d A water flow test will provide data on theavailable water flow in gallons per minute(gpm), static pressure available, and availableresidual pressure for fire protection systems. If a local water service is not available, an onsite well system may be needed. An on-site wellsystem may be needed to provide water fordomestic use and fire protection systems. TheEnvironmental Protection Agency should becontacted to make an evaluation of theproposed well system. The Site Design Professional should evaluate theneed and method of providing gas service to thebuilding. If natural gas service is not available,the installation of liquid propane (LP) gas shouldbe investigated. Utility Services should be placed underground,where possible. Overhead lines, if required,should be placed away from play areas andplaygrounds. Electrical transformers and other utilityappurtenances should be placed away from playareas, playgrounds, and pedestrian walkways, oradequately fenced to prohibit student access.Site Preparation Consider clearing - site vegetation only asnecessary for building, parking, roads, andwalks. Adequate space should be available on-site forconstruction staging – location of stockpiles,portable field offices, storage of constructionmaterials, and equipment. Consider methods to reduce the loss of soilduring construction by storm water runoffand/or wind erosion, including topsoil. Sediment should be prevented from running offinto storm sewer or receiving streams. Every effort should be made to minimizedisruption to the site.Codes and Zoning Incompatible or nonconforming zoning maynecessitate a zoning change variance or aspecial exception land use permit. Zoning ordinance restrictions such as buildingheight, setback, fence height, landscaping,screening requirements, placement and designof site signage and size of parking spaces canaffect site development costs and flexibility.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 20198

4000 Site Selection and DesignAdjacent Property Screening of noise and views may berequired.Minimizeenvironmentalpollution. Consider the safety of children walking toand from the school site during use ofoutdoor athletic and play facilities. Adjacent railroad rights-of-way or busystreets may require the use of earthberms, landscaping, and/or fencing.Easements/Rights-of-Way Easements and rights-of-way for roads,sewers, gas, power, water, and oil linesshould be researched for potentialdevelopment restrictions. Acquisition of additional rights-of-way maybe required to accommodate left turnlanes, tapers, passing blisters, and utilityextensions.Environmental restrictions Wetland delineation must be performed ifthe presence of a wetland is suspected. A designated wetland may prevent sitedevelopment. Mitigation may be needed if a wetland isto be disturbed. Consider air pollution reduction methods.Testing A Phase I Environmental Assessment shouldbe completed to evaluate the potential forenvironmental liabilities associated withcurrent and past property use and toassess regulatory compliance. Consider performing a site investigationand records search of hazardous materialsused, stored, or disposed of on theproperty; proximity to landfills; adjoiningproperty uses; proximity to propertieslisted on the United States mental Response, Compensation,and Liability Information System.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 20199

4000 Site Selection and DesignTesting – cont’d A Phase II Environmental Assessmentmay be required for areas of the sitewhich indicate the potential forasbestos and other contaminants.Aesthetic considerations It is preferable to choose a site withnatural features compatible andcomplementary to the proposedbuilding and site development.Vehicular Circulation Maintain separate car and buscirculation areas. Buses should notbe required to back up. Diagonal bus parking spaces shouldbe 12 feet to 13 feet wide by thelength of the bus. Spaces may bealigned at a 45-degree to 60-degreeangle to the curb. Angle diagonal bus parking spaces sothe bus exit door will allow childrento exit in front of the adjacent bus. Provideparkingspacesneardelivery/receiving area for foodservice and custodial staff. Locate staff parking near visitorparking for economy of pavementdesign where possible. Staff parkingcan also be located to one side ofthe bus parking lot in the area notrequired for bus traffic. Consult building codes for parkingspace number and size.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 201910

4000 Site Selection and DesignPedestrian Circulation Consider constructing walks a minimumof 8-foot wide and a maximum of 12foot wide from major drop-off drives tomajor entrances.Minor connectingwalks are to be a minimum of 5-footwide. Walks should be reinforced concrete, aminimum of 4 inches thick, with lightbroom finish. Consider thickened orreinforced edges. Walk slope should be a minimum of 1percent and a maximum of 1:20. Ifwalk exceeds 1:20, it should bedesigned as a ramp. Provide bollards at main entrance walkto block vehicles.Storm Sewer System Create positive drainage away frombuilding.Collect storm water in aseries of inlets or swales to be detainedand filtered on-site. Connect the building site stormdrainagesystembymeansofdownspouts or roof drains to thebuilding storm drainage system. All storm piping should be designedusing the 10-year return period andintensity-duration curves consistentwith the region. All storm piping and culverts shouldhave a smooth interior. All pipes with adiameter greater than 24 inches shall beconcrete, aluminized steel, or HDPE. Design the project site to maintainnatural slope and water flows bypromoting infiltration. Reuse storm water volumes generatedfor non-potable uses such as landscapeirrigation, toilet and urinal flushing, andcustodial use.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 201911

4000 Site Selection and DesignDetention Pond Detention ponds should be designed toprevent storm water from flowing off thesite at a rate greater than permitted bytheauthoritieshavingjurisdiction.Detention ponds are normally dry exceptafter rainfalls. Side slopes should not exceed 4:1 and maybe increased to 2:1 in the immediatevicinity of headwalls or other dischargecontrol devices. All detention ponds which serve an areagreater than 15 acres should be designedusing an appropriate hydrograph method.The inflow hydrograph shall be routedthroughthepondusingstandardengineering methods to obtain thedischarge hydrograph. Provide riprap or other erosion controlmeasures at inlet and outlet of pond. Storm water detention/retention pondsshould be placed away from play areas andplaygrounds, where practical. Safety ofthe student should be considered toprevent accidental access or accidentaldrowning. Fencing, landscape barriers,transition zones, or other buffers may beutilized where student safety is a concern.Sanitary/Sewage The disposal of sanitary sewage to thelocal utility should be approved by thelocal authority having jurisdiction. Appropriate methods for the disposal ortreatment of sanitary sewage consists ofconventional gravity sewer, force main,septic with leach field system, or sandfilter and on-site treatment plants.Directional Signage Provide “Stop”, “Yield”, “No Parking”,“One-Way”, “Do Not Enter”, or other signsas necessary to maintain a fluid trafficstream. Signs, and the installation of signs, are tomeet the requirements of the authorityhaving jurisdiction.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 201912

4000 Site Selection and DesignPlaygrounds Play equipment to be in compliancewith “ASTM F 1487-95 or most currentversion of the Standard ConsumerSafety Performance Specification forPlayground Equipment for Public Use”and the current guidelines for publicplay equipment by the United StatesConsumer Product Safety Commission. The design of play equipment shouldcomply with Americans with DisabilitiesAct guidelines. Provide a firm, stable, slip-resistant,and resilient soft surface under andaround play equipment. Depth andtype of soft surfaces should complywith ASTM F 1292-99 or most currentversion of Specification for ImpactAttenuation of Surface Systems Underand Around Playground Equipment. Provide an accessible route of travelthrough soft-surface play area. Choiceof surfacing and minimum areas ofsurfacing required should comply g Provide a minimum 10-footcandleillumination level at main buildingentrances.Provide a minimum 5footcandle illumination level at allentrances except main entrance. Light fixtures should incorporate eitherhigh-density discharge or LED typelamp/fixtures located directly overdoors, or recessed in overhangs orsoffits located directly over doors.Fixtures shall be designed for exterioruse. Wall-mounted fixtures shall bevandal resistant. Provide a minimum illumination level of0.5 foot-candles at entrance/exitdrives. Provide a minimum illuminationof 1.0 foot-candles within parking areasand a minimum of 3.0 foot-candles atbus drop-off/pick-up areas.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 201913

4000 Site Selection and DesignLighting – cont’d Lighting should incorporate either highintensity discharge or LED type lamp/fixtureslocated on poles with a concrete base. Poleheight shall be a maximum of 39 feetdesigned to withstand wind loading andoverturning of the selected pole and fixture.Where possible, light poles should be placedbehind curbs to prevent vehicular contact.Lighting shall be controlled by photoelectriccells, time clocks, or time managementsystem. The Site Design Professional shouldhave discussions with the School District todetermine light fixture switching and timeclock programming. Site lighting should be coordinated with thearchitectural outdoor lighting. Minimize site lighting where possible andmodel the site lighting using a computermodel. Consider shielding all site lighting andminimize uplighting.Landscaping Should not exceed 3:1 slope on lawn areaswhere mowing is required. On slopes greater than 3:1, provide slopecontrolled vegetation to retard erosion.Consider safety of children. Provide low maintenance shrubs andflowering trees to emphasize main buildingentries. Consider limiting or eliminating the use ofpotable water for landscape irrigation. Landscape design should include attention toappropriate plant selection on the basis of:plant hardiness zones, avoidance of hazardousplant material (toxic, poisonous, thorny,etc.), avoidance of plant materials withundesirable litter/fruit dropping, species thatare indigenous or well adapted to the region,and plant material that is less susceptible toinsect issues. Native species and droughttolerant species should also be considered.Positive Drainage At building perimeter, exterior grade shouldbe 8 inches or more below first floor level,except at entrances. The ground around thebuilding perimeter shall slope down and awayfrom the building for a minimum of 20 feet toeliminate any standing water.Arkansas Public School Academic Facility Manual - Chapter 4December 30, 201914

Provide parking spaces near delivery/receiving area for food service and custodial staff. Locate staff parking near visitor parking for economy of pavement design where possible. Staff parking can also be located to one side of the bus parking lot in the area not required for bus traffic. Consult building codes for parking
