The application is to rezone land along the north side of I-465 between Pennsylvania Street and College Avenue to permit the construction of office buildings, a hotel, and related supporting service businesses. A more extensive report has been prepared which describes the existing conditions and the proposed development. The reader is referred to that report for a comprehensive review of those topics. This report focuses on the transportation plan and traffic operational improvements proposed by the developer to mitigate potential adverse effects on the roadway system which serves the site and the surrounding community. DESCRIPTION OF PROPOSED PROJECT The development which is proposed by the Trammell Crow Company for the site is an integrated one containing complimentary and supporting types of buildings and tenant uses in a parklike setting. The conceptual site plan is shown by Figure 1. A full service hotel containing 200 rooms, meeting space, and a small restaurant is a secondary feature in the conceptual plan. Flanking the hotel and scattered throughout the site are six office buildings containing a total of 750,000 square feet of gross floor area (GSF). It is expected that business firms may occupy some of the ground floor spaces of the office buildings. In order to provide a maximum amount of landscaped and natural areas, the conceptual site plan indicates that a portion of the parking spaces may be provided in structures. - 1 - II - , � . j . _ iI i. 1 _ 1 J ; I -1 -]1 _ i .‘1 )i . , lilt _ F { ! , I . . i II _ - I II 'Ax ' OVID, *--'A .. . f t r ' . 0,, I ) 11011111 M.a _ ''' vi 4- -; *a' i 01. iipip---c---,7:-7j- ,... ...._.ri,, . , 1( li , III -ri,t,—71— 7, t - ..-. !_a_ ,--1,,,i_,!,__-__ ‘ _..)- 7 ,,,..i.s. 1- -.di it .-;::,_;,:,,,r., .

These objectives were established early in the planning process in consideration of both broad community interests and the specific requirements of the site. As such, the transportation plan addresses the short term need to complete the Pennsylvania Street _ extension to relieve congestion along Meridian Street. In addition, the plan acknowledges the desirability to improve the I-465 interchange by deferring development on land adjoining it until the extent and timing of such improvements becomes known. These significant transportation objectives were incorporated into the Conceptual Site Plan along with other site planning objectives to: * create a buffer area between the development and the residential neighborhood, * reconstruct existing drainage ways and create new water detention features, * minimize surface parking areas and maximize landscape and natural areas, * provide transition from high intensity highway development to moderate density residential neighborhoods. - 3 - -. 11 o I - j.'

Table 1 summarizes the trip generation estimates. TABLE 1 Estimated Trip Generation of Potential Development Average Weekday Traffic Type of Approx.

Based upon residential and commercial patterns it is estimated that more than half (55%) of the trips will have origins and destinations south of the site. For instance, 1980 U.S. Census data reveals that 58% of the families which then resided within four (4) miles of the site lived south of the Marion-Hamilton County line. The balance of trips (45%) will have origins and destinations north of the site. - 5 - - TRAFFIC ACCESS ANALYSIS The amount of traffic expected to be generated during the morning and evening peak hours has been assigned to roadways in consideration of the directional distribution factors. The results of the traffic assignments are shown by Figure 3. The site will have multi-directional access with the completion of the extensions of 103rd Street and Pennsylvania Street. As a result site traffic will be dispersed throughout the roadway network. - During the morning peak hour period, about 770 vehicles are expected to enter the site from the south; about 460 from along Meridian turning right into the site, and about 310 from along College turning left into the site. About 700 trips will arrive from the north and be delivered to the site by Meridian, Pennsylvania, and College. During the evening peak hour period, about 700 vehicles are expected to leave the site toward the south; about 415 turning left onto Meridian from 103rd Street, and about - 280 turning right onto College. Within the site, traffic volumes will meet, or exceed 1000 vehicles per hour in one direction - during peak periods. Therefore, two lanes in each direction will be provided through the site along the extension of Pennsylvania Street. The two lanes in each direction will be separated by a variable width median to enable landscaping to be installed and left turn lanes provided at the various building and parking facility driveway. OFF-SITE TRAFFIC IMPROVEMENTS - Traffic operations along the meridian Corridor are critical to this development site, neighboring development sites, the local community and the region. The corridor directly serves trips which originate or are destined to nearby site, trips between Carmel and - Indianapolis, and long distance regional trips. As such developers, the City, the County and the State all have important roles in implementing short range traffic operational improvements and planning long range highway projects which will serve the corridor. Short Range Traffic Operational Improvements Short range traffic operational improvements are planned by the developer to mitigate - the impact of traffic generated by this proposed project. With the approval of the Indiana Department of Highways, local agencies, neighboring _ developers, and nearby residents, Trammell Crow Company will improve 103rd Street and its intersections with U.S. 31 (Meridian Street) and with Pennsylvania Street as shown by the conceptual plan in Figure 4. The conceptual plan for the intersection of 103rd Street and U.S. 31 (Meridian Street) acknowledges the proposed westward extension to serve the announced Meridian at the Interstate project. The conceptual plan indicates that 103rd Street would have two lanes - in each direction. This arrangement would allow for free flowing right turns to be made to and from U.S. 31 (Meridian Street) and dual left turns to be made from 103rd Street. - 6 - Nl f" 9I_ g1 fN d ....._1_5 _ __ — 1 1 _ 20 — 75 — 1 150 140 -106th St. - - - - I I — 140 5 20 � - - - — � — I I _ _ _ —106th St. 150 — — - 1 1 — 510 5 I I 1 IS 20 — — - 1 I 0 I I _5 I 1 140 I I I I 1 I— I I 1 1 I ;I I I 1 I 1 ;l 1 I n ♦1N < I I C 0 1< 1 I N�NI N1=f" 1�1 M�NfN N�=fN �1 — ISI ISI NI0 I 1.I ^1,IN IBI W 1B1 IJi m IWI 121 lo, IWI 121I-I ot 2 ,IWI u 2 IWI u — 10 Is 75 1 4 I I I 70 I I 685 I n I I I 103rd St. I I 103rd St. I I 5 I — 765 — I I I I tp - - - I i— 11 6 — 1L II I �lf� II ; ;0 0 I I I IN OUT I I1435 120 • 1 — I I 160 1330 Yj f'� 1 7S i,� 3S SO 5S �_ _— 1525 165 � _ ,I210 1385 A _ _ 60 485 "l Jh I tir/0h i M 19N _ - 1.-% 1-465 1-465 T .- T MORNING PEAK HOUR EVENING PEAK HOUR FIGURE 3 _ ESTIMATED PEAK HOUR TRAFFIC GENERATED BY PROPOSED DEVELOPMENT OF THE _ TRAMMELL CROW COMPANY - 7 - � I 3 '414 P5 I VINV/VIASNN33- - --- - / / / --- lr I I ' I I r 0 1 I I H Q I I U wQ I w J all w I I v zz II Qw I � � I I w v Ii Z O M I I i U 0 tZ 3{ 3 i I FIGURE 4 I I 1£ -s'n - 8 - The conceptual plan further includes the installation of a multi-phased, multi-dial, traffic actuated signal at the intersection. The signal controller should have the capability to be interconnected with other signals along the corridor and to be supervised by a master system controller. The warrants for such a signal at this intersection are currently met based on a formal traffic signal warrant study which was commissioned by the Trammell Crow Company and submitted to IDOH for its review. Should IDOH concur that the traffic signal is warranted, then Trammell Crow Company will install the signal and implement the conceptual plan for the intersection and the improvement of 103rd street at its expense as a part of its initial preparation of the site for development. The conceptual plan for 103rd Street, shown by Figure 4, indicates that its intersection with Pennsylvania Street would favor the major traffic movements to and from the proposed development site. In constructing this intersection, 103rd Street will be realigned to discourage non-residential traffic from passing through the existing neighborhood. The conceptual plan for 103rd Street and U.S. 31 (Meridian Street) has been subjected to a Level of Service (LOS) analysis as shown by Figures 5 and 6. Figure 5 illustrates the LOS analysis for the morning peak hour period. The analysis considers existing traffic, and traffic expected to be generated by both this proposed project and the announced Meridian-at-the-Interstate along the west side of U.S. 31 at 103rd Street. The analysis indicates that a multi-phased signal with overlaps, and dual left turn lanes from 103rd Street will provide a Level of Service D during the peak morning hour. At LOS D the expected mean stopped delay of vehicles entering the intersection may be in the range of 30 seconds as shown by Table 2.

The analysis indicates that Level of Service E would be provided during the evening peak hour with mean vehicle delays exceeding 40 seconds as shown by Table 2. The proposed intersection at College Avenue is shown by Figure 7. It is proposed that College Avenue be widened on the owner's (west) side to enable a northbound left turn lane to be installed. A traffic signal at this intersection will not be warranted based upon site traffic alone. However, other traffic diverted from Meridian Street as a result of the new site roadway may contribute to the ultimate need for a signal at this location. Long Range Capital Improvements Continued development along the Meridian corridor in both Carmel and Indianapolis makes it incumbent upon the public and private sectors to examine interchange and corridor — improvements to increase the Level of Service provided to roadway users. The Indiana Department of Highways (IDOH) is currently engaged in a study of critical interchanges throughout the State. In recognition of the IDOH planning study, the Trammell Crow Company will defer new development on its land which is immediately adjacent to the interchange so as not to preclude the improvement of the geometry and capacity of the ramps. This commitment to defer development will remain in effect for a period of ten years or until such time as the improvement of the interchange is determined to be not feasible by IDOH due to cost or encroachments by new developments in other quadrants of the interchange. The commitment to defer new development will exclude the new service-access driveway to connect with the Meridian Street frontage road as shown by Figure 2. SUMMARY The Conceptual Site Plan has been designed in consideration of the following transportation planning objectives which are illustrated by Figure 2: * extend Pennsylvania Road south and east through the site to College Avenue thereby providing a new outlet for the site and other development along the east side of the Meridian Corridor; * improve 103rd Street and its intersection with Meridian Street (U.S. 31) as a primary access; * defer development near the interchange of I-465 for ten years pending a determination by IDOH of the extent and timing of improvements which may require additional right-of-way; * provide secondary access for service vehicles from Meridian Street frontage road; _ * provide circulation for internal site traffic; * provide east-west route continuity while diverting traffic from adjoining residential neighborhood. - 13 - _ These objectives were established early in the planning process in consideration of both broad community interests and the specific requirements of the site.
