1 3.13 Trffic nd Trnsporttion This section describes the ffected environment nd regultory setting for trnsporttion nd trffic. It lso describes the impcts on trnsporttion nd trffic tht would result from implementtion of the project, nd mitigtion mesures tht would reduce these impcts. Additionl informtion on trnsporttion nd trffic is provided in Appendix I Environmentl Setting The three proposed project sites re locted in n unincorported re in Imperil County, north of the City of Cliptri nd est of the Almo River. The southern boundry of the Cliptri I project site borders the northern city limits of the City of Cliptri, nd is within its sphere of influence. Midwy I nd II re locted over mile northwest of the city of Cliptri. Highwy 111 is the lrgest public rod to bisect the City of Cliptri nd the generl vicinity of the project site. Cliptri I is pproximtely one hlf of mile est of highwy 111, Midwy II is pproximtely one hlf of mile west of highwy 111, nd Midwy I is bout 1.5 miles west of Highwy 111. The three project sites re primrily bounded by public rods. Cliptri I is bounded by Blir Rod to the est, Young Rod to the south, West Lindsey Rod to the north, nd frmlnd to the west. Midwy I is bounded English Rod to the est, Sinclir Rod to the north, Est Peterson Rod to the south, nd privte rods to the west. Midwy II is bounded by English Rod to the west, Est Hoober Rod to the north, Montgomery Rod nd West Lindsey Rod to the south, nd privte rod to the est. Access to the Cliptri Solr I is vi Blir Rod. Access to the Midwy Solr Frm I site is vi Sinclir Rod. Access to the Midwy Solr Frm II site is vi English Rod. Bsed on the nticipted distribution of project trffic, the nlysis contined in this section focuses on the following intersections nd street segments.

5 3.13 Trnsporttion nd Trffic The two closest primry public use irports to the project site re the Brwley Municipl Airport nd the Imperil County Airport. Brwley Municipl Airport is in the City of Brwley nd locted pproximtely 9.7 miles to the southwest of the Cliptri site; it is used for generl vition (AirNv 2010). Imperil County Airport is locted in the City of Imperil pproximtely 20.9 miles from the Cliptri site. Imperil County Airport is primrily generl vition fcility, but is served by one commercil irline. The site is locted bout one third mile northest of the Cliff Htfield Memoril Airport (generl vition trffic only nd light commercil jets/prop jets). The site is locted within the irport plnning re/irport influence re for Cliff Htfield Memoril Airport s defined in the ALUCP, Imperil County Airports (Imperil County, 1996). The site is prtilly locted within Zone B-1 Approch/Deprture Zone nd Adjcent to Runwy nd Zone C Common Trffic Pttern which re defined in Chpter 2 of the ALUCP. However, due to the nture of the proposed solr plnt, the project would not chnge ir trffic ptterns or result in n increse in ir trffic. As prt of the Conditionl Use Process, the pplicnt ws required to obtin determintion from the ALUC regrding the consistency of the proposed project with lnd use policies nd stndrds dopted by the Imperil County ALUC nd described in the ALUCP, Imperil County Airports (Imperil County, 1996). The ALUC held public hering on the Cliptri I site (70SM 8ME/CUP # ) on My 18, 2011 nd found the project inconsistent with the 1996 ALUCP. Specificlly, the ALUC found tht the development pln for the Cliptri I site did not reserve sufficient open spce res for emergency lnding of ircrft using the nerby Cliff Htfield Memoril Airport. To ccommodte the concerns of the ALUC, the pplicnt hs since revised the Cliptri I site pln by widening the distnce between the southern site fence line nd the first solr pnel from 30 feet to 50 feet, which would llow for emergency lnding of ircrft. This revision to the site pln for Cliptri I ddresses the ALUC s concerns. Rilrods The north-south-trending trcks of the UPRR border the west side of the Cliptri I project site. Midwy II is just over 1mile west of the rilrod trcks nd similrly, Midwy I is just over 2 miles west of the rilrod trcks. There re no stops or pssenger ril service within the project re. Therefore, no trnsporttion impcts relted to rilrods re nticipted, nd this issue is not discussed further in this DEIR. Trnsit Service While Imperil Vlley Trnsit provides inter-city fixed route bus system in Imperil County, no trnsit service is provided in the immedite vicinity of the project re. Bicycle nd Pedestrin Fcilities No bicycle or pedestrin improvements hve been mde in the immedite project vicinity. Imperil County Plnning & Development Services Deprtment ESA /

6 3.13 Trffic nd Trnsporttion Existing Trffic Opertions Level of Service Approch Level of service (LOS) is the term used to denote the different operting conditions tht occur on given rodwy segment or intersection under vrious trffic volume lods. It is qulittive mesure used to describe quntittive nlysis, tking into ccount fctors such s rodwy geometries, signl phsing, trvel speed, trvel dely, freedom to mneuver, nd sfety. LOS provides n index to the opertionl qulities of rodwy segment or n intersection. LOS designtions rnge from A to F, with LOS A representing the best operting conditions nd LOS F representing the worst operting conditions. LOS designtion is reported differently for unsignlized intersections, signlized intersections, street segments, nd freewy minline. The following describes the LOS designtions for unsignlized intersections, street segments, nd freewy minline. Street Segments Street segments were nlyzed bsed upon the comprison of Averge Dily Trffic (ADT) to the County of Imperil Rodwy Clssifictions, LOS nd ADT tble (see Tble , below). Tble provides segment cpcities for different street clssifictions, bsed on trffic volumes nd rodwy chrcteristics. Segment nlysis is comprison of ADT volumes nd n pproximte dily cpcity on the subject rodwy.

7 3.13 Trnsporttion nd Trffic Unsignlized Intersections For unsignlized intersections, level of service is determined by the computed or mesured control dely nd is defined for ech minor movement. Level of service is not defined for the intersection s whole. Tble depicts the criteri, which re bsed on the Averge control dely for ny prticulr minor movement. TABLE LOS THRESHOLDS FOR UNSIGNALIZED INTERSECTIONS Averge Control Dely per Vehicle (Seconds/Vehicle) Level of Service A 10.1 to 15.0 B 15.1 to 25.0 C 25.1 to 35.0 D 35.1 to 50.0 E 50.1 F LOS F exists when there re insufficient gps of suitble size to llow side street demnd to sfely cross through mjor street trffic strem. This level of service is generlly evident from extremely long control delys experienced by side-street trffic nd by queuing on the minorstreet pproches. The method, however, is bsed on constnt criticl gp size; tht is, the criticl gp remins constnt no mtter how long the side-street motorist wits. LOS F my lso pper in the form of side-street vehicles selecting smller-thn-usul gps. In such cses, sfety my be problem, nd some disruption to the mjor trffic strem my result. It is importnt to note tht LOS F my not lwys result in long queues but my result in djustments to norml gp cceptnce behvior, which re more difficult to observe in the field thn queuing.
