CORRESPONDENCE Hallalilllri.Kevin From: Hallahan, Kevin Sent: Thursday, April 07, 2005 12:47 PM To: 'Sandra Lee' Subject: RE. Emailing: revised mitigation Sandra, o . Are the quantities of newly proposed plant materials for the open areas equal to the total quantities on the previous plan now in review by the City? . I am concerned that the exotic invasive grasses and weeds will outgrow the large areas of proposed small native plantings especially through the summer rainy months. You may want to have the maintenance company review the plan for weekly maintenance after planting. . You may want to place some (more) of the proposed larger saw palmetto plants near the outside edge of the preserve to act as a people barrier .. I would recommend that your proposed plan include signage telling people they cannot go into the preserve area. . I would recommend that your plan include temporary (orange) snow fencing to tell the construction crews they cannot go into the preserve area. . 1 would recommend your plan include an immediate replacement provision for plantings that die or are damaged as the general contractor calls for building(s) landscape inspections. 1 will re-inspect the preserve area on each request for a building landscape inspection. If you have any additional questions., contact me. Thanks. Kevin. -----Original Message----- From: Sandra Lee Jmailto:SLeelfilCalvin..aiordano,coml Sent: Wednesday, April 06, 2005 3:51 PM To: hallahank@ci.bovnton-beach.fl.us Subject: Emailing: revised mitigation << File: revised mitigation.pdf>> <<revised mitigation.pdf>> Please take a look at the revised mitigation plan for the Canterbury Preserve.

PRESERVE AREA CRITERIA CANTERBURY Monitoring and maintenance programs will be implemented upon completion of the installation of the plant materials within the preserve area. The goal of the monitoring program is to ensure the establishment and long-term viability of the designed habitat functions. The goal of the maintenance program is to ensure the successful eradication of invasive exotic plant species that would disrupt the success of the designed habitat functions. During year one, 100% of survival of installed species is required, replacements must be installed as needed. A ~survival of installed species must be demonstrated by the end of year two. 100 ( I II>deF,^,Te) Routine maintenance to remove and eradicate invasive exotic vegetation will be ongoing from construction throughout the entire monitoring phase. Maintenance will involve physical and chemical eradication methods. The maintenance program is designed to ensure no more than 5% coverage of invasive species. Maintenance will be conducted no less than quarterly, and may be more frequent, as needed, especially during the rainy season. Signage, at least one foot by one foot in size will be placed on each side of the preserve area which reads "Preserve Area, do not enter, do not disturb or remove vegetation" The perimeter silt fencing will remain in place until construction of the entire site is completed. o m1~"lvin, l:jiordano !Associates, Inc. .

The results of the traffic study mdIcated that wIth SIgnal tImmg modIficatIons, coupled wIth the re-stnpmg of the north approach, the mtersectIOn would operate at an acceptable level of servIce ThIS recommended Improvement was revIewed by City staff and the report was forwarded to Palm Beach County Traffic DIvIsIOn for theIr reVIew Please note that the eXIstmg and proposed mtersectIon geometry IS depIcted m Figure 1 PrelImmary dIscussIOns wIth County staff after theIr reVIew have mdlcated theIr concern wIth the overall operatIOn of the mtersectlOn of Gateway Boulevard and HIgh RIdge Road at a pomt m the future several years beyond the constructIon of the commItted developments Further, they have requested that the SIgnalIzed mtersectlOn capacIty analysIs evaluate the mtersectlOn based on ItS current maxImum cycle length of 140 seconds m order to facIlItate coordmatIOn wIth the SIgnalIzed 1-95 mterchange ramps at Gateway Boulevard. It has been generally accepted that the mtersectIOn of Gateway Boulevard and HIgh RIdge Road WIll operate at an acceptable level of servIce at the bmldout of the SIX (6) IdentIfied comnlltted developments adjacent to the subject mtersectIon. GIven that, we have grave concerns that the requested background traffic growth for Gateway Boulevard, added to the commItted development traffic after buildout, WIll be the baSIS for addItIonal mtersectIOn Improvements that the commItted developments WIll be responsible for W ebelIeve that any traffic operatIOnal problems at the mtersectlon that arIse explIcItly because of background growth traffic, whIch occurs after the bmldout of a prolect, are not the responsibIlIty of the developer However, It IS clearly m the cOlmmtted developments' best mterest for the mtersectlOn to operate effiCIently Mr Mike Rumpf April] 0 2003 Page 2 of5 Therefore, thIS supplementary analysIs IS provIded to evaluate the future traffic operatIons of the mtersectIon of Gateway Boulevard and HIgh RIdge Road after the buildout of the SIX (6) projects and determme when the mtersectlOn wIll fall to operate at an acceptable level of servIce. Study Methodology Future Turning Movement Volumes - The standard procedure to estImate background growth for a roadway segment IS to apply a hlstoncal growth rate, developed from several years of relIable average daIly traffic volumes, to the eXlstmg daIly volume. ThIS relatIvely sImple method IS not, however, the generally accepted method to determme future peak hour turnmg movement volumes at an mtersectIon. The reason IS that applymg a hlstoncal growth rate to mdlvldual turnmg movement volumes may madvertently overestImate a turnmg movement volume onented towards a roadway that does not exhibIt strong potentIal for addItIonal growth. In that case, the specIfic movement may realIze background traffic at a rate less than the overall lInk's average growth, while counterbalanced by an underestImate of the background growth assocIated for a dIfferent turnmg movement at the same approach. Therefore, applymg a lInk growth rate to specIfic turnmg movement volumes IS sIgmficantly less accurate than IdentIfymg the antIcIpated growth for all mtersectlOn approaches and mdlvldual turnmg movements. However, smce commItted development traffic estImated for the peak hours of operatIOn have been dIstributed through the mtersectlOn, only the remammg turnmg movements on Gateway Boulevard not sIgmficantly Impacted by the commItted development must be addressed. In an effort to sImplIfy the future turnmg movement volume forecast, the hlstoncal growth rate calculated for the Gateway Boulevard lInk west of 1-95 was dIrectly applIed to the eXlstmg peak hour turnmg movement volumes at the subject mtersectlOn. The basIs of the roadway segment growth rate comes from the most recent Palm Beach County data collected from 1998 through 2001 on Gateway Boulevard east of HIgh RIdge Road. Data from Palm Beach County StatIOn #4213, located on Gateway Boulevard 150 feet east of High RIdge Road, mdlcated that traffic has been growmg along thIS segment at a 467 percent rate for the past three (3) years. However, If traffic data from thIS statIOn were evaluated from 1999 through 2001, a background growth rate of approxImately 1 0 percent would result. ThIS growth rate fluctuatIOn from one year to the next IS mdlcatIve of the vanatlOns m traffic volumes that generally occur, as well as the overtly large growth rate calculated for Gateway Boulevard from 1998 through 2001 that IS likely not sustamable over a long-term honzon. However. m the mterest of analyzmg the worst case scenano conceIvable for the future traffic operatIOns at the mtersectlOn of Gateway Boulevard and HIgh RIdge Road. thIS traffic analysIs utIlIzed a compound growth rate of 4.67 percent (the hIghest growth rate calculated for Gateway Boulevard m the ImmedIate vlcmlty) to estImate background traffic for the peak hour turnmg movement volumes on Gateway Boulevard not sH~mficantly Impacted by the commItted development traffic already accounted. Because a greater traffic volume travels through the mtersectlOn dunng the PM peak hour than the AM peak hour, thIS supplementary analYSIS only evaluates traffic operatIons dunng the PM peak hour Figure 2 summanzes the resultmg future PM peak hour turnmg movement volumes forecasted for the mtersectlOn of Gateway Boulevard and HIgh RIdge Road. Please note that the background growth rate of 4 67 percent applIed to the turnmg movements on Gateway Boulevard slgmficantly unaffected by the commItted developments (eastbound through, eastbound nght turn, westboUnd through, and westbound Mr Mike Rumpf April] 0, 2003 Page 30f5 left turn movements) IS only apphed to the eXIstmg traffic volume and not the summatIon of the eXIstmg traffic volume and commItted development traffic. The traffic generated by the SIX (6) commItted developments IS layered on top of the eXIstmg plus background traffic volume forecasted for those movements resultmg m a total future turnmg movement volume forecast. Future Signal Timings - The sIgnal tImmgs and phasmg currently Implemented at the mtersectIOn of Gateway Boulevard and High Ridge Road provIde for a sIx-phase operatIOn dunng the AM peak hour wIth a cycle length of 130 seconds, and a five-phase operatIOn for the PM peak hour WIth a 120-second cycle length. However, based on extensIve field observatIOns of the mtersectlOn's traffic operatIons, the mtersectlOn typIcally operates WIth a reduced cycle length and number of phases because of the sIgnal actuatIon present at the north and south approaches, as well as the eastbound and westbound left-turn lanes. ThIS actuatIon prOVIdes a more effiCIent operatIon by shortemng the green time asSIgned to a partIcular phase If no traffic volume IS present. Because of the moderate to hght demand on High Ridge Road, a SIgnIficantly large percentage of the total green tIme provIded at tills mtersectlOn IS asSIgned to traffic on Gateway Boulevard at the present tIme. As a result, the cycle length IS typIcally much shorter than 140 seconds and some phases are bypassed completely If vehIcles are not present, even dunng the peak hour However, the capablhty does eXIst to mterconnect the sIgnahzed 1-95 mterchange ramp mtersectIons WIth Gateway Boulevard at High Ridge Road usmg a common cycle length of 140 seconds. Therefore, the future year sIgnahzed mtersectIOn capaCIty analyses contamed herem were performed usmg thIS cycle length, as requested. Please note that thIS, too, represents an effort to analyze the future traffic operations of the subject mtersectIon under the worst case scenarIO, smce cycle lengths longer than the optImum duratIOn denved from traffic volume tend to result m SIgnIficantly greater vehIcular delays. Future Traffic Operations Analysis GIven the traffic operatIOnal defiCIencIes IdentIfied preVIOusly for the mtersectIOn of Gateway Boulevard and High RIdge Road, sIgnal tImmg and lane geometry modIficatIons appear necessary to accommodate the future traffic demand at the north approach. These Improvements WIll accommodate the expected travel through the mtersectlOn when the SIX (6) commItted developments are completed to ensure that the mtersectIon will operate at an acceptable level of servIce by mImmIzmg the Impact the left-turn queue WIll have upon traffic operatIOns on High RIdge Road upstream of the mtersectIOn. Based on prevIOUS analYSIS, It IS eVIdent that a smgle left-turn lane at the north approach cannot accommodate the antIcIpated future traffic volume, where the southbound left-turn alone IS estImated to be approxImately 450 vehIcles dunng both the AM and PM peak hour Therefore, It was recommended that the north approach be re-stnped such that It WIll conSIst of an exclUSIve left-turn lane, a shared left- through lane, and a shared through-nght lane. GIven these geometnc modIficatIons, the current SIgnal tImmg, willch prOVIdes protected-permItted phasmg for the northbound and southbound left-turnmg movements, IS no longer VIable. Smce future projected peak hour turmng movement volumes for High Ridge Road mdIcate a large volume of traffic generally onented southbound, resultmg m southbound and northbound approach volumes that are SIgnIficantly dIfferent, It was recommended that the traffic SIgnal tImmg be modIfied to mclude spht phasmg for the north and south approaches. It was also recommended that actuatIOn be retamed for the north and south approaches to Improve the overall effiCIency of traffic operatIOns, partIcularly dunng the off-peak penods when traffic volume on HIgh RIdge Road IS conSIderably less than that observed dunng the peak hours. ThIS WIll ensure that Mr Mike Rumpf April 10 7003 Page 4 of5 traffic travelIng on Gateway Boulevard will receIve pnonty and operate wIth reduced delay, partIcularly when traffic on HIgh RIdge Road dIssIpates. A sensItIvIty analYSIS was performed to determme the traffic operatIOnal Impact the forecasted background growth WIll have upon the mtersectlOn of Gateway Boulevard and High RIdge Road assummg the recommended re-stnpmg and SIgnal tunmg modIficatIOns are Implemented. Further, tIns analYSIS attempts to ascertam when the adrntIOnal background traffic will cause the mtersectlOn to fail such that It operates at an unacceptable level of servIce. The SIgnalIzed mtersectIon analYSIS was performed m several mcrements through 2015 and IS summanzed m detaIl m Table 1, while the senSItIVIty analYSIS IS summanzed m Table 2 A detailed summary of the SIgnalIzed mtersectIon analyses for the PM peak hour forecasted for 2004, 2006, 2008, 2010, 2012, and 2015 IS shown m Table 1 Even gIVen that the cycle length will remaIn at 140 seconds and that the extremely conservatlve 4 67 percent annual compounded background growth IS sustamed for each IdentIfied tummg movement on Gateway Boulevard, results mdIcate that the mtersectIon WIll operate overall at an acceptable Level of ServIce D dunng the PM peak hour through 2010, gIVen the re-stnpmg and SIgnal tImmg Improvements. AnalYSIS of the 2012 PM peak hour revealed that the operatIon of the mtersectlOn would degrade to Level of ServIce E+, WIth delays exceedmg 60 seconds per vehIcle. It should be noted, however, that the volume- to-capacIty ratIo for the overall mtersectlOn was estImated to be 0.90, and no mdlvldual approach volume- to-capacIty ratIo IS expected to exceed 1 00 Also, all mdIvIdual turnmg movements are expected to operate at no worse than Level of ServIce E and delays should not exceed 80 seconds per velucle, wluch typIcally represents the threshold for a SIgnIficant operatIOnal faIlure of a movement. Because a catastrophIc failure IS not expected to occur dunng the PM peak hour of 2012, a subsequent analYSIS was performed for the forecasted peak hour traffic volumes dunng 2015 Results of the SIgnalIzed mtersectlOn capaCIty analYSIS mdIcated that the overall mtersectlOn would also operate at Level of ServIce E. However, the north and south approaches of the mtersectlon (High RIdge Road) are expected to operate at Level of ServIce F, WIth velucular delays m excess of 110 seconds per velucle. Further, the westbound through movement on Gateway Boulevard IS also estImated to operate at Level of ServIce F, WIth velucular delays of almost 85 seconds. V olume-to-capacIty ratIOs are expected to exceed 1 00, mrncatmg that traffic volumes forecasted for the peak hour exceed the capaCIty threshold for the movement. Clearly, tlus analYSIS mrncates that. due to the addItIonal background traffic above and beyond the commItted development traffic from the SIX (6) prOlects, the mtersectlon wIll fail to operate at an acceptable level of servIce m 2015 gIVen only the recommended re-stnpmg and SIgnal tImmg modIficatIons. Table 2 presents the companson of the future PM peak hour traffic operatIOns analYSIS of the mtersectIOn of Gateway Boulevard and High RIdge Road by approach and the overall operatIon of the mtersectIon, assummg the recommended re-stnpmg and SIgnal tImmg modIficatIOns are Implemented. As shown, the mtersectlOn wIll contmue to operate at an acceptable level of servIce through 2010, even though comrmtted development traffic WIll be realIzed well before then. Please note that all of the sIgnahzed mtersectIOn analyses for the future condItIons analyzed m tIns supplementary submIttal are attached for your reVIew Mr Mike Rumpf April] 0 2003 Page 5 of5 Conclusions and Recommendations Calvm, GIordano & AssocIates recently submItted a study evaluatmg the traffic operatIOns at the mtersectIOn of Gateway Boulevard and HIgh RIdge Road. In partIcular, concern was expressed that msufficIent capacIty eXIsts to accommodate the southbound-to-eastbound left turn when the commItted developments adjacent to the mtersectlOn are constructed and occupIed. The results of the InItIal traffic study IndIcated that the IntersectIOn would operate at an acceptable level of servIce, provIded SIgnal tImIng modIficatIOns and the re-stnpIng of the north approach were Implemented. The report was forwarded to Palm Beach County Traffic DIvIsIon for theIr reVIew by the CIty of Boynton Beach at the completIOn of the City's revIew PrelImInary dIscussIOns wIth County staff have IndIcated theIr concern wIth the overall operatIon of the IntersectIOn of Gateway Boulevard and High RIdge Road at a pOInt In the future several years beyond the constructIon and occupatIon of the commItted developments. Therefore, a senSItIVIty analYSIS was performed to assess the Impact to the IntersectIon that background traffic growth wIll have upon the traffic operatIOns of the IntersectIOn, and determIne when the addItIonal traffic volume assocIated wIth background growth causes the mtersectIOn to faIl to operate at an acceptable level of servIce Based on thIS supplementary traffic analYSIS of the worst-case scenano usmg the most conservatIve background traffic growth assumptIOns aVaIlable (and dIrectly applymg these growth factors to the mtersectlOn's peak: hour tummg movement volumes), It IS concluded that the mtersectlOn of Gateway Boulevard and High RIdge Road WIll operate at an acceptable level of servIce through 2010 gIven the recommended Improvements. It IS clear that the nitersectlOn will operate at an acceptable level of servIce by the buildout of the SIX (6) comrmtted developments, and that the antICIPated traffic Impacts that these developments WIll have upon the mtersectIOn will be mItIgated through the recommended re-stnpmg and SIgnal modIficatIOns for many years post-buildout.

The sIte IS generally located north of the mtersectlOn of Gateway Boulevard and High RIdge Road m the CIty of Boynton Beach. ThIS sIte, WhICh IS contamed wIthm the Quantum Park Develop of RegIOnal Impact (DRI), obtamed master sIte plan approval from the CIty ConnlllssIOn on October 15, 2002 for 39 fee-sImple multI-famIly resIdentIal dwellmg umts (attached for your revIew) GIven thIS approval and certam sIte plannmg logIstIcal Issues, Westbrook CompanIes proposes to develop only 36 multI-family resIdentIal dwelhng umts on Lot 89B The followmg assesses the transportatIon Impacts assocIated wIth the proposed development, and smce the DRI has already been approved, IS submItted to determme If the proposed development exceeds the amount of traffic vested for Lot 89B Please also note that a copy of the Palm Beach County Traffic DIVISIon approval letter for Quantum Park - VIllage North for 136 multI-famIly umts as well as 102,235 square feet of commercIal development IS attached. ThIs was mcluded to clanfy any potentIal mIsconceptIOns regardmg Lot 89B and Quantum Park - VIllage North. WhIle these two sItes have been conceptually planned m a coordmated fashIon because of theIr proXImIty to each other, the sItes are mdependent and must receIve separate approvals. Thus, thIS letter IS submItted on behalf of Lot 89B to address traffic Impact concerns. Traffic Analysis Trip Generation Analysis The tnp generatIOn charactenstIcs for the approved and proposed multI famIly resIdentIal development were estImated based on rates and equatIOns for multI-famIly developments m Palm Beach County and the InstItute of TransportatIOn Engmeers' (ITE) Trip Generation Manual, 6th EdItIon, 1997 Mr Mike Rumpf January 29 2003 Page 2 of2 Table 1 summanzes the tnp generatIOn analysIs. The approved 39 fee-sImple dwellmg umts are estImated to generate 273 daIly tnps, whIle the proposed 36 multI-family umts WIll generate 252 daily tnps. ThIS equates to a net dally tnp reduction of 21 tnps, or eIght (8) percent. Due to the net dally tnp reductIOn assocIated WIth the proposed multI-famIly resIdentIal development on Lot 89B, thIS project WIll not exceed the number oftnps It IS vested for per the Quantum Park DR!. Conclusions Calvm, GIOrdano & AssocIates has analyzed the traffic Impacts assocIated WIth the proposed development near the mtersectIOn of Gateway Boulevard and High RIdge Road. Smce the proposed multI-famIly resIdentIal development WIll generate fewer daIly tnps than the currently approved SIte, Quantum VIllage at Quantum Park Lot 89B does NOT exceed the level oftraffic that It IS vested. Based on these findmgs, we recommend that the proposed development be approved.
