Linden Ave is currently 22’ wide with one side of on-street parking. We have requested a variance through the state for deficiency this and the mitigation that we have come to with Chief Parsons is to change the non-paid on-street parking in front of our building located at 210 Linden Ave to a 15 min loading zone. We would like to request that this change be made. Thanks, Chris Petrillose VP of Development: Visum Development Group DEVELOPMENT GROUP Page 4 of 10 B.

I was given you name by Tim Logue in reference to the following inquiry and request. Friendship Donations Network (FDN) celebrates its 30 year rescuing food otherwise going to landfills, redirecting it to community pantries and public food programs, and thereby reducing hunger. Our volunteers daily pick up food from businesses around the city and, in particular (but not exclusively) in collegetown, sometimes they get parking tickets. Volunteers avoid no parking areas and time involved in a pickup is usually under l0 minutes. They are instructed to park in loading zones and legal spaces (without feeding the meter). We are writing to request the City permit a small number of FDN drivers be allowed to park without being ticketed or paying. Ifa permit can be displayed or method worked out using parkmobile.com we could supply the license plates and/or other information needed.

Resolution to Grant Hardship Request for 326 Mitchell Street For Residential Parking Permit System WHEREAS, the Board of Public Works (BPW) has promulgated regulations, adopted June 9, 2004, for implementation of the Residential Parking Permit System (RPPS), which was established by Common Council on May 6, 1998 after an act of the New York State Legislature, and WHEREAS, in accordance with Section 260-4 of the City Code and in accordance with the BPW regulations, the BPW may grant hardship requests, and WHEREAS, 326 Mitchell Street is on a street within the residential Parking Permit Zone without on-street parking and is within the R-1 zoning designation; therefore allowing up to two permits per single family dwelling, now, therefore be it RESOLVED, that the Board of Public Works hereby grants the residents of 326 Mitchell Street to purchase permits for the Residential Parking Permit Systems, in accordance with the above- mentioned regulations. Page 7 of 10 BACK-UP INFORMATION FOR ITEM 13(D) To: Board of Public Works From: Eric Hathaway, Transportation Engineer Date: October 23, 2017 Re: Residential Parking Permit System Hardship Request 326 Mitchell Street I am recommending approval of the enclosed Residential Parking Permit System (RPPS) hardship request from Laura Burch, a resident at 326 Mitchell Street. Section 260-4 of the City Code, Residential Parking Permit System: Exemptions, states four circumstances in which a resident may apply to the Board of Public Works for a permit not otherwise available. The third case is, “where residents living on a street within the Residential Parking Permit Zone without on-street parking wish to purchase a permit for on-street parking on a street where permits are required.” Ms. Burch lives on Mitchell Street, which is within the Residential Parking Permit Zone A. Mitchell Street does not have parking on either side of the street. Ms. Burch wishes to purchase a permit for on-street parking on a street where permits are required. I see no issues with granting a hardship for a residential parking permit for 326 Mitchell Street. Page 8 of 10 E. Traffic Calming Investigation To: Board of Public Works From: Eric Hathaway, Transportation Engineer Date: 10/19/2017 Re: Proposed Traffic Calming Program Methodology The attached is an updated form that citizens can use to request traffic calming in the city of Ithaca. The updated form would allow a non-resident of a block to request a traffic calming study on a block and to be the contact person. The form now also specifies that if there are no residences on a block, then no resident signatures are required on the form. Further, the form now clarifies that traffic calming requests should be for sections of roadway under 1,000 feet in length in order to allow for consistent and sufficiently detailed analysis of all locations. I ask that you consider whether you support these changes to the existing form. City of Ithaca - Request for Traffic Calming Investigation If you would like to have the City Engineering Department consider your request for traffic calming, you will need to fill out the following sections and send the completed form to the City of Ithaca Engineering Department (attn: City Transportation Engineer) at 108 E Green Street, Ithaca, NY 14850. What is traffic calming? Traffic calming measures are intended to make streets safer and more attractive for people to walk, bike and drive by reducing the negative impacts of motor vehicles such as excessive speeds and/or volumes of traffic. Traffic calming measures may consist of educational, enforcement and engineering efforts. Some examples of traffic calming measures are: driver speed feedback signs, targeted police enforcement, pavement markings, signs, speed humps, chicanes and diverters. What is the Selection Process? Received requests will be prioritized based on factors related to traffic speeds, volumes and other considerations, such as proximity to schools. The Engineering Office will work with relevant City entities to determine what types of traffic calming measures may be appropriate. Final approval will be granted by the Board of Public Works (BPW). A. Street Study Information Each request must provide the name of the street on which a study is requested and the boundaries of the street segment. Boundary limits may change at the discretion of the Engineering Department. Please use street names for boundary limits, not block ranges. In order to provide consistent and sufficiently detailed analysis at all locations, requests must be limited to sections of roadway 1,000 feet or shorter. Requested Street: __________________________________________________ Boundary Area: From (Street): _______________________________________________ To (Street): __________________________________________________ B. Contact Person Information Each request must provide a contact person. The contact person will receive all correspondence and will be responsible for gathering evidence of support. If there are no residents on a requested block, no signatures are required, but a contact person must still be established. Name: ______________________________________________________ Address: ______________________________________________________ Phone #: ______________________________________________________ E-Mail Address: I agree to be the contact person for the above request: Signature: _____________________________________________________ Date: _________________________________________________________ C. Nature of the Traffic Concern We believe the nature of the issue we would like to have addressed is (be as specific as possible): ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ________________________________________________________________ D. Evidence of Neighborhood Support Please provide evidence of neighborhood support for participation in the program. The attached form can be used for this request. Individuals providing signatures must live or own a property within the study area as identified in Section A. Signatures from residents representing at least 1/2 of the households whose property is next to the street segment in question is required for consideration. Additional copies of this page may be submitted to secure the required number of signatures. We the undersigned owners and residents of ______________________________ hereby offer our support for our neighborhood’s participation in the traffic calming study. It is important to understand that the traffic calming countermeasure selected by City staff may require the removal of on-street parking and can increase on-street noise levels.

A Resolution To Amend Chapter 346 of the City of Ithaca Municipal Code entitled “Vehicles and Traffic”, Section 346-12 entitled “Stop Control Intersections” Including Discussion Related to All-Way Stop Warrant Analysis For Cayuga Street – Cascadilla Street – Cascadilla Avenue Intersections WHEREAS, the Board of Public Works is authorized by Section 346-4 of the City Code to adopt and to amend a system of Schedules in order to administer the Vehicle and Traffic Law, and WHEREAS, the City’s Transportation Engineer has determined that the intersections of Cayuga Street and Cascadilla Avenue should be changed to all-way stop control to improve safety and operation, now therefore be it RESOLVED, that the Board of Public Works hereby adopts the amendments below: Schedule VIII: Stop Control Intersections. In accordance with the provisions of §346-12, the following described intersection is hereby designated for control by an all-way stop as follows: Cayuga Street and Cascadilla Street The following intersecting street or location is hereby designated for control by stop sign(s) (not “all-way”): Intersection Direction of travel Cayuga Street and Cascadilla Avenue Northbound/Southbound J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc All-Way Stop Sign Warrant Analysis for Cayuga Street/Cascadilla Street/Cascadilla Avenue Intersection. Evaluated by Eric Hathaway, Transportation Engineer Summary of issue: Bridge Engineer Addisu Gebre is improving conditions along the Cascadilla Creekway this summer/fall through a construction project, so we have collaborated to include improvements at the nearby intersection of Cayuga Street with Cascadilla Avenue in his scope of work. We have worked with Labella Associates to create a design that optimizes safety and accessibility at this intersection. As part of this design effort, we have concluded that an all-way stop condition is an appropriate next step as described in this memorandum. Per the City Code, a change from 2-way stop operations to 4-way stop conditions requires Board of Public Works approval. Manual on Uniform Traffic Control Devices (MUTCD) All-Way Stop Warrant Analysis: The MUTCD provides the following guidelines in Section 2B.07 (Multi-Way Stop Applications). Each of these criteria are evaluated in the following sections. Support: 01 Multi-way stop control can be useful as a safety measure at intersections if certain traffic conditions exist. Safety concerns associated with multi-way stops include pedestrians, bicyclists, and all road users expecting other road users to stop. Multi-way stop control is used where the volume of traffic on the intersecting roads is approximately equal. 02 The restrictions on the use of STOP signs described in Section 2B.04 also apply to multi-way stop applications. Guidance: 03 The decision to install multi-way stop control should be based on an engineering study. 04 The following criteria should be considered in the engineering study for a multi-way STOP sign installation: J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc A. Where traffic control signals are justified, the multi-way stop is an interim measure that can be installed quickly to control traffic while arrangements are being made for the installation of the traffic control signal. B. Five or more reported crashes in a 12-month period that are susceptible to correction by a multi-way stop installation. Such crashes include right-turn and left-turn collisions as well as right-angle collisions. C. Minimum volumes: 1. The vehicular volume entering the intersection from the major street approaches (total of both approaches) averages at least 300 vehicles per hour for any 8 hours of an average day; and 2. The combined vehicular, pedestrian, and bicycle volume entering the intersection from the minor street approaches (total of both approaches) averages at least 200 units per hour for the same 8 hours, with an average delay to minor-street vehicular traffic of at least 30 seconds per vehicle during the highest hour; but 3. If the 85th-percentile approach speed of the major-street traffic exceeds 40 mph, the minimum vehicular volume warrants are 70 percent of the values provided in Items 1 and 2. D. Where no single criterion is satisfied, but where Criteria B, C.1, and C.2 are all satisfied to 80 percent of the minimum values. Criterion C.3 is excluded from this condition. Option: 05 Other criteria that may be considered in an engineering study include: A. The need to control left-turn conflicts; B. The need to control vehicle/pedestrian conflicts near locations that generate high pedestrian volumes; C. Locations where a road user, after stopping, cannot see conflicting traffic and is not able to negotiate the intersection unless conflicting cross traffic is also required to stop; and D. An intersection of two residential neighborhood collector (through) streets of similar design and operating characteristics where multi-way stop control would improve traffic operational characteristics of the intersection. MUTCD Multi-Way Stop Sign Warrant Section 1: The intersection of Cayuga Street and Cascadilla Street experiences fairly high levels of bike and pedestrian traffic, especially during the afternoon. From 4-5 PM, over 226 pedestrians have been observed crossing any of the four legs of the intersection (66 crossing Cayuga Street). These crossing movements can add complexity for turning vehicular and bike movements when not all movements are required to stop. However, traffic volumes are not balanced between the Cayuga Street and Cascadilla Street approaches, as described later. J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc MUTCD Multi-Way Stop Sign Warrant Section 2: The general principles of this section apply to use of stop signs. MUTCD Multi-Way Stop Sign Warrant Section 3: The following sections summarize the engineering study undertaken for this analysis. MUTCD Multi-Way Stop Sign Warrant Section 4: Subsection A: Not applicable Subsection B: 5 Year Crash History: An evaluation of the Accident Location Information System (ALIS) was conducted for a 5 year period from 2012-2016. There were 12 total crashes listed for the intersection during this period. The following table illustrates the breakdown of crash type: Table 1 – Crash Summary (2012-2016) Crash Type Number of Crashes Rear-End 5 Sideswipe 2 Right Angle 2 Pedestrian 1 Overtaking 1 Bike 1 As previously mentioned, the MUTCD offers guidance that a minimum of five left-turn or right-turn crashes are required during a 12-month period to warrant an all-way stop based on crashes alone. The highest number of crashes occurring at this intersection during a twelve month period was six, four of which were rear-end crashes. Only two of the twelve crashes involved left-turn or right-turns from the side street. However, based on staff observations and on feedback received from the community, “near misses” occur J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc regularly at this location when cars on eastbound Cascadilla Street start to pull out, but then stop when they see southbound vehicles approaching. This phenomenon can add confusion for pedestrians waiting to cross the roadway. Subsection C: Traffic Count: A 5-hour traffic count was conducted at the intersection on September 29, 2016 to determine the existing traffic and pedestrian volume levels. Counts were conducted from 7:45 AM-9:45 AM, 11:15 AM-12:30 PM and 3:15-5 PM to get a representative sample of the peak hours of a typical weekday. The peak hour occurred from 8-9 AM, with vehicular volumes of 779 total on the Cayuga Street approaches and combined vehicular/pedestrian volumes on the Cascadilla Street approaches of 189. The traffic count results are contained in the appendix. Based on the counts, main street traffic is sufficient to warrant all-way stop conditions for the five hours of data collected; however, current combined side street counts (vehicles and pedestrians) are generally slightly lower (122-201) than the recommended 200 vehicles per hour required for eight hours of the day. However, upon completion of the creekway project and the proposed bike boulevard markings, it is likely that there will be more bikes crossing this intersection in the future. It should be noted that, though the side street volumes do not meet the minimum thresholds, the second part of Criteria 4.C.2 is met. Through use of Synchro traffic software analysis, the printout sheets in the appendix shows that estimated current side street delay on the eastbound Cascadilla Street approach, during the 3:30 PM-4:30 PM period, exceeds 30 seconds/vehicle during the peak hour (32.9 seconds/vehicle). Upon installation of a four-way stop, it is estimated that delay on this approach will be reduced to 10.7 seconds/vehicle. However, installation of a four-way stop condition will increase delay and queue lengths on Cayuga Street, especially during the morning peak hour when southbound vehicular demand is higher. It is projected that during the 8-9 AM and 3:30-4:30 PM weekday peak J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc periods, the 95th percentile queue length will be approximately 9 cars on the southbound approach, which would extend past Farm Street, to near Kinney Drugs. Per Synchro analysis, average southbound delay would increase to 23-28 seconds per vehicle during the morning and afternoon peak hours. It should be noted that, even without stop signs on the Cayuga Street approaches, queue lengths associated with the signalized intersection of Seneca Street/Cayuga Street to the south back up past Cascadilla Street during some peak times (especially around 9 AM), so southbound queue lengths might not be severely impacted through installation of a stop sign on the southbound approach. Projected traffic operations during “off-peak” times was also studied to determine the expected traffic condition for most of the day. During the 11:30 AM to 12:30 PM time period, delays on the southbound approach are projected to be just over 11 seconds per vehicle, with 1-3 cars in queue at any time. Based on this finding, it is projected that delay and queue lengths for most of the day will be minimal on all approaches. The Section 4.C.3 speed warrant is not met, as the 85th percentile speed does not exceed 40 miles per hour on any approach. A summary of observed speeds is listed below and the accompanying data can be found in the appendix. • Cayuga Street north of the intersection, 4546 ADT southbound, 1684 ADT northbound. • Cayuga Street south of the intersection, 4465 ADT, 85th %tile speed 28.7mph southbound, 1722 ADT, 85th %tile speed 30.3mph northbound. • Cascadilla Street west of the intersection, 1497 ADT, 85th %tile speed 26.8mph eastbound, 1080 ADT, 85th %tile speed 27.2mph westbound. • Cascadilla Avenue east of the intersection, 44 ADT, 85th %tile speed 15mph westbound (along north side of creek), 45 ADT, 85th %tile speed 14mph westbound (along south side of creek). Subsection D: J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc Subsectuion D criteria are not met, as the previously described warrants are not all met at 80 percent. MUTCD Multi-Way Stop Sign Warrant Section 5: The primary reasons for installing an all-way stop condition at the intersection of Cayuga Street and Cascadilla Street are Subsections B and C of Section 5. The Gimme Coffee shop on the southwest corner of the intersection appears to be a high generator of pedestrian trips, both from the neighborhood and downtown, as well as from individuals parking along the street and walking into the shop. This is a strong contributor to the over 220 pedestrians observed crossing the varying legs of the intersection during the 4-5 PM period. There also appears to be an eastbound/westbound pedestrian commuter trend with heavier eastbound volumes in the morning and heavier westbound in the afternoon. Adding stop signs could simplify decisions for vehicles, especially on the Cayuga Street approaches. Currently, trailing vehicles might be unsure if a leading vehicle will yield to a pedestrian waiting on the side of the road. With an all-way stop, the stop will be mandatory, regardless of whether the pedestrian has entered the crosswalk. The measured sight distance looking north on Cayuga Street from a stopped vehicle on the eastbound Cascadilla Street approach is approximately 143 feet, if taken 14.5 feet from the curbline of Cayuga Street, per American Association of State Highway and Transportation Officials, standards. In order to get the desirable 335 feet of sight distance for left-turns from the minor street, based on a speed of 30 mph on Cayuga Street, a driver would have to be positioned nearly even with the bridge rail, which is approximately 6 feet from the curb edge on Cayuga Street. Many vehicles have been observed pulling up far enough to achieve the needed sight distance, but others have been observed hesitating to make the maneuver or not coming to a full stop before proceeding. Vehicles encroach on the crosswalk on Cascadilla Avenue when they pull up to maximize sight distance to the north. J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc Therefore, we asked Labella Associates to explore the option of moving the curb out on the west side of the bridge, in order to allow vehicles to pull up further on the eastbound Cascadilla Street approach and eliminate the need for all-way stop conditions to address sight distance. This is feasible; but would cost approximately $40,000 between engineering and construction costs. Moving the curb ramp out over the bridge would also make it impossible to ever continue the southbound bike lane south, past the intersection with Cascadilla Street, without another construction effort to move the curb back to its original location. The option of providing a “bulbout” at the southwest corner of the intersection to reduce Cayuga Street crossing distance, by Gimme Coffee, was also explored, but it was found that this would cause TCAT buses turning from westbound Cascadilla Street to southbound Cayuga Street to encroach on the oncoming lane. A bulbout will be constructed at the southeast corner to reduce crossing distance for pedestrians. As proposed, the southbound lane over the bridge will be reduced to 10 feet in width through painting and goring, instead of by moving the curb. This goring will provide flexibility of merging bicycles that a curbed lane would not. Recommendation: It is our finding that an appropriate initial approach is to install an all-way stop condition at the intersection of Cayuga Street and Cascadilla Street. The primary reason for changing to an all-way stop is to reduce the need for sight distance looking north on Cayuga Street from a stopped vehicle on the eastbound Cascadilla Street approach. Additionally, the all-way stop could improve conditions for pedestrians, cyclists and vehicles approaching on Cascadilla Street from the west, by forcing vehicles to stop on the main street. However, southbound and northbound vehicles on Cayuga Street will experience significant additional delay during peak times. After a period of months, the conditions can be re-evaluated to determine if an all-way stop has been successful in creating a J:\TRAFFIC\Studies\stop signs\Cayuga and Cascadilla\All-way stop for Cayuga- Cascadilla 9-20-17.doc better pedestrian environment and improving conditions for vehicles approaching from the west on Cascadilla Street. These potential improvements can be weighed against increased southbound and northbound delay on Cayuga Street. If the all-way stop is not operating as well as anticipated, design options could be considered to encourage vehicles on the eastbound Cascadilla Street approach to feel comfortable pulling further out, to optimize sight distance.
