Since the location of Northtork is within two miles o! 'the Village o! Teqvesta limit�, � Traffic Engineerinq, inc. was asked to ide�tiPy and evaluate the � potential tratfic imp�+cts to the Villaqe. 1 The review ot the traffic imp�cts o! the NorthPork DeveloQment was ' based on input from severnl sources. The result is n comprehensive review of the project impacts and potenti�l trafPia conditions in ! the area o� the Village ot Teqvesta. � 1 1 SUMMARY � � � The results of this Traffic impact Review o!. the Northfork � Development include certain conclusions regarding future traffie conditions in the Village of Tequesta and the rel�+tive impact of � Northfork itself. Althouqh the traffic generation from Northfork i will certainly flow into the Vil2aqe of Tequesta, it was demonstrated that this is siqnificantly muted by a re-orientation � of shopping related travel which is expected to occur. Furthermore, future conditions on Country Club Drive and Tequesta � Drive were examined to isolate the future need for the County Line , Connector Road. ' Yt is concluded that besides siqnificant roadway improvements�south of Northfork !n the Palm Beach County, Northfork should participate � in the completion of the County Line Connector Road to help remedy ' existing Martin County traffic impacts which effeet the Villaqe of Tequesta. � . � � . � � � � � � � � • / � . � � S 3 'I`RAF P I C MHTfi000I.OG1f Since Northfork i� located in Ma�rtin Cou�ty, a traftic impact analysis waa pertormed accordinq to the Martin County quidelines, which difter aliqhtly from what aould be required in the Village o! Teqvesta or by Palm Beach County. Theretore, a hybrid traFtio methodology was developed to ide�tity �ctual traftie impacta to the �Villaqe o! Tequesta. �ordination�f Sour�e� e Severa�l sources were reviewed a►nd incorpora�ted into this analysis. The primary source was the t�orthlork Tran�nortation imoac� s*����• bY David Plummer d� Associates in October 1991• and submitted to Martin County. Additionally, other traftic enqineering studies and related market analyses were reviewed. o A market study analysis submitted with the October 1990 submission to Martin County prepared by Sunbelt Research Associate�, Inc. o A Kimley-Horn and Associates report for a proposed project on the same Northfork property submitted to Marttn County in October 1990. o The �ithern Conne�.�o� Road Studv prepared by PRC Harris in 198) for Hartin County. , These various sources of informat3on have been combined into the analysis which is presented in this report. Also, other agencies have reviewed the Northfork application includinq Palm Beach County and Town of Jupiter. . Coordination with Applican� Over the last several weeks, the Applica�t for the Northfork project and representatives of David Plummer � Associatea have been very helpful and cooperative in Working aith the Village of Tequesta representatives to Pocus on the true extent o� the traffic impacts to the Villaqe. Several technical ite�ns havs been addressed in these meetinqs and are reflected a� a part this report. 2 r r � r � r r � r r ` ` � � � �► �r v� �. �► �r �r �r w �r �► .r �. � � � �- ' + COUi ll�f� Ad • .i � ..� E �! �t�wr�ov ao�t�wn' �• ' p ��: �:. ��, �� w � °°„� R �' t r.

Y Several i�aue� were presented in the Plummer'� ana�y�i� ahich do not serve to �dequately address the traffic impacts in the Village o� Teqvesta. �or example: o Tra►f�ic generation estimates, with respect to the level o! pass-by capture, aere under e�timated. ' o Distribution �nd a►ssiqnment ot project traffic to the surrounding roadway network under estimated tha � potentinl impacts on Country Club �rive and Tequest� Drive. ' o impact area analyzed waa too small to include dll � roadways which will absorb project related traffic, especially those in the Villaqe of Tequesta. � Assumptions and methodologies related to each of the three areas � were readdressed by Traffic Engineering, Ine., With siqnificant � input from the Villaqe, the Applicant and David Plummer. Specifically: � . o A more reasonable estimate of traffic generation 1 was calculated based on revised pass-by capture ' assumptions. � o A reassessment of project traffic distribution and assiqnment was undertaken usinq a qravity model and 1 market research o� both the residential and ! commercial elements of the Northfork site. j o A revised impact area was determined to more adequately include an analysis of the net traffic � impacts to the Villaqe ot Tequesta. . , Each of these items were also pointa of concern expressed in a � letter from Palm Beach County dated February 4, 1992. This letter and other correspondence from Palm Beach County is included in � Appendix �►. In some cases, adjusEinq these input assumptions and ' methodologies resulted in signfficantly diflerent conclusions. Each of the three issuea addressed above will be the subject of > following sectiona o� thi� report. � 5 ' - � � � � � . , � , ��• . ., ' �� TRAFFIC CHNERIITION The David Plummer report calculated the external traftic that would � be generated trom the proposed Northfork site to be 6,956 daily � , trips. Exhibit 6A trom the report 112ustrate� the result� ot these calculations and is included in Appendix e. � � � ,�nt�rn�►li�ation � The Plummer report estimated the percent of Korthtork that will be satisfied on site. Speciticdlly, the Pollowinq reductions and ' tot�l traltie generationa were applied to account !or this � internalizations � 0 20 percent ot the residential traffic, � 0 20 percent ot the Northfork retail trips, . � 0 15 percent of the office traf Pic and, ► • 0 60 to 65 percent of the recreational trips. ' Although Palm Beach County questions some of these assumptions, it � is felt that they accurately reflect the internalization expected � from the Northfork Development. ► Pass-Bv Capture � Pass-by traffic relates to the phenomenon that a significant � percentaqe of traffic to a well-Iocated retail center is simply captured from traffic already passing by the site and is not new I traffic. Plummer assumed that 62 Qercent of the retail related , trips were to be captured from traffic passing by on the new Central Bou2.evard Extension. � However, pass-by capture can be applied only to the exten� that it ! accounts for 25 percent of the passinq traffic. Since only 2,005 � daily trips are exp�cted on the Central Boulevard extension in 1998, {not fnc2uding traffic qenerated fro�a the Northfork, � Development) pass-by traffic must be 2imited to only 501 trips. This increases tha totnl external traffic qeneration from Northfork / ;to 7,519 daily tripa. � 6 1 1 1 � . , �' , ' ` • ' , CRJ►VITY MODBL FOR OI5TRIBUTION � . ' A qredt dea►1 of eftort wA� put into the reassessment oF the � distribution oi Northfork project traftic to the surroundinq , roadway network. Severdl hours o! meeting� were held r+ith the Applicant to refine a gravity model for diatributio�. � � pis �b�.,�lon o� NoFthtork Trirs � This gravity model focused o� each of the trip purposes of the Northfork project including: � � o Trips produced froca the Northfork residential � component to neighborhood retail in the aren. 1 � o Trips produced from the Northfork residential � portion of the site to other regional attractions. � o Trips being attracted to the Northfork retail � component of the site. � o Trips being attracted to the Northfork office and recreation uses of the site. 1 � The details of this gravity model are illustrated in Figure 2 and supported by tables and other figures found in Appendix C. � � R�-�rientation of Tria� � Presently trips on Country Club Drive are from the surroundinq resfdential area. A significant percentaqe of these home-based � trips are oriented towards retail uses for the purpose of shopping. �• The absence ot any shoppinq opportunities nearby makes it necessary for these drivers to travel up to five railes for even the most � convenience-oriented shopping purpose. 1 Applying the gravity model developed for this report demonstrates , that the introductioa ot retail uses on the Northfork Deve2opment will attract shoppfnq related trips from residential uses in the � area. The net traffic impacts from the Northfork project will be discussed in the next section. � � � � � � � � � . � � a � --� o � �o � v �i �� � �- � � � � � . � � t t 1 � ..�., ' 1, ti ==�..o =• h - �-=_ =_.�._. , '� � .

This is � equivalent to approximately 16 percent ot the total external ' project traffic generation. � ! The allocation of these trips to Country Club Dri�ve and Tequesta Drive is illustrated in Fiqure 3. Zt shows that impacts to Country ) Club Drive just south of Island Way are expected to be y approximately 710 dai2y trips. This decreases on links further south and east so that Tequesta Drive is expected to experience 431 � additional daily trips from the Northfork project. 1 The Effect of Re-oriented Tripg � The introduction of a retail center at the Northfork site will � attract a certai� percentage of the home-based shopping trips in the area and re-orient them from their present travel along Country � Club Drive and Tequesta Drive. Detai2ed calculations of this i phenomenon are included in Appendix D and illustrated in Figure 4. � The net traffic impacts range from 1,132 trips on Island Way to 110 trips on Tequesta Orive. i � 9 � � 1 � � � � � � S�. � �0 ��� ��Z w� � �o Central BNd.

Even more important than the potenti�+l tratt'ic impacts from Northfork is the dbility Eor the Villege ot Tequesta to maintain � acceptable level o� service on Tequesta Drive. This is potentially , very important within the context o! concurrency. The Villaqe needs to maintain the ability to approve fUture developmenta, but ' it is equally critic�l to con�ider the operdting condition� tor the � existing citizens o! Tequeata. , �xis�in4 Conditions ' To better understand the conditions throuqhout the Country Club � Drive and Tequesta Drive corridor, tr�tfie counts were collected by Traffic Engineering, Ine. in Februnry 1992.

These conclusions are important in ev�aluating future roadway needs in the Tequesta and Martia County areas. Fj��ure Conditions It can be expected that the two lane section of Tequesta Drive, east of Seabrook Road may be over capacity on a peak season basis wfthin the next ten yeara. Thi� is based on potential growth in the area which will add traffic to Tequesta Drive, includinq buildout ot approved project� in Martin County and luture developments from within the Village of Tequesta and elsewhere in Palm Beach County. it must be noted that projects in Martin County which will impact the vfllaqe of Tequesta in the future were given approvals prior to the 1985 Grawth Manaqement �1ct and implementation o! current local Comprehensive Plans. The Yillage of Tequesta �houl� maximize the communica�ions called for fn the.interqovernmental Coordination Elements ot the Comprehensiva Plana to control and mitigate future traffic impacta lrom developments outside the V112aqe. . 13 • � . , � � SkudY �►rea G nti�aratien� A� mentioned, this �tudy was performed u�inq a hybrid methodology developed ,to mosti accuratoly asses� tr�ftic impacts trom the ' Northtork Development.

Therefore, Tequesta Drive considerati�ons should be a part of the traffic analysis for Northfork. � 14 9 • P ' ' ' � � KBCOt4�8NDSD ROJ1D1iAY IMPROYt�'I'a ' � Certain roadwey improvements will bo necessary to mitigate the lmpACts From the Northfork project. These includo improvements ' which are needed to; � o F�cilitate and encourage a�ccess to the south to � Indiantown Road, and � o To maintain fuEure level or service within the � � Village ot Tequesta. ► imprQVement in the Palm Bea�� County � Both the Plummer and Traftic Engineerinq, Inc. analyse� concluded � that the following roadway improvements are necessary; � o Extension of Central Boulevard through Northfork to Island Way. ••o•� Extension of Longshore Drive to intersect with the Central Soulevard extension. o Construction of a four lane divided Central Boulevard from south of the C-18 Canal to Church Street, including the necessary bridqe widening. o Signalization at the intersection of Central Boulevard and Church Street. These roadway improvements are illustrated on Fiqure 5. They are consistent with the David Plummer's report and correspondence from Palm Beach County related to the 1990 Northfork application which is found in �►ppendix A. They are also critical to attracting trips to the south frorn Northfork and thereby reducing impacts from Nortbfork to the Village of Tequesta. Improvements for the Villave of Te�uesta • Roadway improvementa !or the Villaqe of Tequesta are needed so that the Vi.11aqe can mafntain acceptable operating conditions and still accommodate tha impacts frora futuro approved and proposed development in the V112aqe and Martfn County to the north. 1S ' � � � i � � � � � 3 � �i �. � � � � m y � � N � K O 3 � � �e ti � s . . o �_ ��'-i— • . h ` 0 � � � i � f 1 1 � � �. � , CONNECTOR ROAD 1►LTERNJ1TIYiL It is not desirable to expand Tequesta Oriva to accommodate tuture traffic volumes identified in a previou� aection ot thi� report. � The expansion would violate community goals and objectivea expressed in the Comprehensive Pl�n nnd Would severely lmpdct � adjacent propertie�, 'rhe coat would be extremely high. � Furthermore, a full expansion to tour lnne aould provide an �sseas ot capncity over wha►t would be needed, even in the ulttmate ' buildout conditions. � Therefore, it is desirable to investigate �lternative improv�ments � which aould benefit the Teqvesta Orive corridor. The County Lin� Connector Road is a feaaible alternative to the exQansion ot � Tequesta Drive Eor several re.asona. �1 very thorough study aas � prepared on this issue by PRC Harris in 1981. Additionally, more timely conditions support the alternative improvement to County , Line Connector Road instead of Tequesta Drive. ' o There are many approved dwellinq units in Martin � County in the immediate area o� the Connector Road. � o Martin County has funded the desiqn of thia connection in their Capital Improvement Plan. � o Zf adequate right of way can be acquired, � construction cpst would be approximately �300,000. � o The Connector Road would siqnificantly reduce ► traffic volumes through the Little Club � development. )' Moreover, indicationa from a analysi� . performed by Traffic Enqineerinq, Inc. for this report are that there is a potential for � approximately 6,000 exfsting and future trips to be diverted to the � County Line Connector Road. This 4rould relieve tbe future traflic impacts on Tequesta Drive and Country Club Orive within the Villaqe � of Tequesta by more than 2,000 daily tripa. � Although this diversion could be quantified more precisely, it � seems qufta reasonable from a professional traffia engineering standpoint, that siqnificant benefits can be realized from the t . 17 � 1 i 1 . �.

There need� to be a Mdrtin County roadway � serving this area. 1 'rherefore, it is recommended that Northfork Development participate , in Punding for the conatruction o� the County Line Connector Roed. This could take the torm o!; 1 o �esponsibility !or actual conatruction o! the � roadway, or � o A commitment that trattic impdct teea be applied to � thia improvement. � The traf f ic impact fees from the Koithlork Developanenti nre expected ' to be approximately 5450,040, which would be in excess ot the preliminary construction estimates for the roadway. ► It may be appropriate to draft a tri-Qarty agreement among Martin 1 County, Palm Beach County and the Villaqe o!

Monterey Road Stuart� Florid� 34996 SUBJECTs NORTHFORK (SECTION 28) TRANSPORTATJON IMPACT REDORT DATE� OCYOBER ll, 1491 ♦ Dear Mr. Nerrinq: The Palm Beach County Engineering OePartment has reviewed a traffic report prepared by David Plumner d� Associates for the proposed Northfork development in Marti� County. The conclusions of this report are similar to another report that was done by Ktmley-Horn and Associates for this same site whlch you requested us to review about one year ago. However, the most recent proposed development on the Narthfork site rvauld increase the number of housing units by about 2b0 to $.�Q� increase the retail area by 5400 square feet (s.f.j to S00 s.�, and add ZSOOO�.f,, of office space. The following conments are offered for your conslderation in evaluating this report: 1) It is stated that 25% of total trips would remain on site as "internal trips'. However, this does not see�a likely, given the relatively small amounts of retail and offtce develapn�ent proposed and given the fact that home-based work and shopping trips constitute � large percentage of daily tripmaking. The consuliant should be required to �ustify this assumotion with a breakdown of internal and external trfps by purpose for the development. � 2j Patm Seach County uses a trip generation rate of 7.0 trips per day for multi-famity restdentiil and prefers�the use of the formulas in the ITE "Trip Generation' (5th Edittonj book in calculating tne retail and office traffic. 3j The pass-by trips of 1064 per day for the 25000 s.f. retail center constitute almost 54x of its total trip qener:tion and over 26.5% of the . diverted �existinq+backqround} tr�ffic on the raadrray through Korthfork. Both of these percentages exceed the maximuras narmatiy permitted by Pala� . 6each County wlthout further �ustificatton. : 'M Equal Opportunity • AftLmaUv�e Actbn Empf°Yer Sor ZI�Z9 W'E.9T PAI.�d B�iCH. ff.OAIDA S34Yd-14�� (40� 6g�..4ppp , i. �• ' . .. � � ` � Pag� tw0 t 4) The pro�ett tr�ffit Oistrtbution is heavily skeweC tow�rd tne Centr�l 81vC � Extenslon/Church Street route (see attacheC Exhibit 1 from the report), Further �usttfication ts necessary, In our opinion� for assigntng 85y of � the traffic to thts roadway when three other possible access potnts exlst: longshore/Northfork Orive, loxahatchee Rtver Road a�d tsland Way/Country � Club Orive. Some of these other �ccess points provide shorter drlvtng Qlstantes to other retall/ employment/recreatton areas. � Also� 1t 1s not clear from the report whether the appllcant is proposlnq ; to construct the Centr�l Blvd. Extension (whlch does not extst at the present tlme). The constructlon of thls roadway wou14 have to be comnitted � slnce the appllcant ts relyinq upon tt as his primary source of access. � S) P�1m 6each County staff agrees that no t.r�fftc capacity problem will probably develop on Country Club Ortve with the approval of thls � development (�s conctuded by the "Northfork (Section 28) Country Club Orive Oetailed Analysis Report" prepared by Oavid Plummer � Associates on October � 21, 1991). Nowever, it may be appropriate to extend the analysls area beyond the normal radius of development influence because the pro,�ect � trafflc would not disperse to any great extent until it reaches the commerclal areas at Tequesta Orive/ Old 01xie Nighway and Tequesta � Drive/U.S. 1. Given the htgher traffic volumes (a 1991 year ADT of 12266) on Tequesta Orive, there may be difficulty 1n meeting the appltcable � traffic standards. This concluston was reached by traffic consultant Frederlck W. Schwartt, P.E. in his January 10� 1492 tetter (copy attached) � to Mr. Scott ladd of tfie Village of TeQuesta. f 6) Normally the Patm Beach County Engineering Department does not review traffic reports (such as the Northfork reports that were prepared by Oavid � Plummer 3► Associates, Inc.j that are � signed and sealed by a professional engineer. � � Please do not hesitate to contact me if you have any questions concerning these comments. . � Sincerely, � OfFICE OF NE COUNTY EN NEER / � e . � Allan A.
