HomeMy WebLinkAboutItem VI (E) Discussion/Action re: Speed Humps AGENDA 3-5-96 Item VI E MEMORANDUM DATE: February 23, 1996 TO: The Honorable Mayor and Bo d of City Commissioners FROM: James W. Shira, P.E. City Engineer/Utilities Director SUBJECT: Speed Humps At the City Commission meeting on December 19, 1995, the basic design principles and traffic requirements and consequences were discussed relating to the installation of speed humps on Ocoee streets. The City Commission requested that we return to them with additional information including a preliminary list of possible locations, the preliminary cost associated with each location, and the various forms that would be required to accept requests for speed hump installation, and to notify affected homeowners of the potential installation. Attached is a copy of my memo to the City Manager dated February 22, 1996 which transmitted a list of locations and the costs associated with each. To my knowledge, the City Commission did not discuss the funding method to be used for the installation of speed humps. My report of December 12, 1995 recommended that the special assessment method be utilized, but I recall that there was some discussion of this being a potential general fund program. In my December 12 report, I included a proposed description of an Ocoee Speed Hump Program. A copy of that description is attached. As written, the program anticipates that residents will submit a petition signed by area residents requesting that speed humps be installed on certain streets. The proposed policy indicates that upon determination that the streets in question meet the required criteria, a ballot would be mailed to each affected property owner to determine their interest in a special assessment. The City Commission needs to provide direction to staff regarding their desired funding mechanism for this program. If, for instance, this is to be a general fund program, there may be no reason to go to the expense of mailing ballots, since interest in a particular street will be evidenced by the initial petition. The proposed policy is a compilation of those currently in effect in Orange and Seminole Counties. If the City Commission accepts this policy, or indicates what changes are desired, and 01 identifies a funding mechanism, we can proceed to prepare the required forms, notifications, petition format, etc. We request that the City Commission decide whether a street hump program is to be implemented in Ocoee, and if so, decide whether it is to be a special assessment program or a general fund program. If this is to be a general fund program, both a funding level, and an implementation date must be established. There are not provisions in the current budget for this program, nor will we have time to implement it as part of the FY 95/96 mid-year adjustment. If this is to be a special assessment program, we recommend that it not be started until FY 96/97. Public support should be sought prior to implementing such a program. Once these decisions are reached, staff can proceed as appropriate to develop proposed policies, procedures and forms. JWS/jbw Attachment MEMORANDUM DATE: February 22, 1996 TO: Ellis Shapiro, City Manager FROM: James W. Shira, P.E. City Engineer/Utiliti rector SUBJECT: Speed Humps The attached list gives approximate lengths for various streets throughout the city which appear to be potential locations for speed humps. The list has been prepared without any regard for local conditions or geometric considerations which may make certain streets unsuitable for speed hump installation. It is impossible to determine, without a detailed study of each location, the exact placement of speed humps that would be compatible with curb inlets, driveways, curves in the road and intersecting streets. Any of these items would affect the location of speed humps in the vicinity, and could cause the total number of speed humps to vary from that shown on the attached list. If a speed hump program is enacted, and one of the listed streets is selected, a detailed study will be made to determine the exact number and location of speed humps to use, which will then define an accurate project cost estimate. This list is by no means an all-inclusive list, since citizen complaints will certainly be used as a method to add to the list of potential installation locations. The cost data on the list is based on an average spacing of 300 feet between speed humps, and an average construction cost of$1,000.00 per speed hump. This cost includes the asphalt for the hump itself, as well as the signing and striping that are required. The study cost is the cost of hiring a firm to collect traffic volume data which is needed to determine if the street is carrying an acceptable volume of traffic to be included in the program. The study costs could be reduced somewhat by grouping several streets together, or by the city purchasing its own traffic counters. The maintenance cost is based on $150.00 per speed hump per year to maintain striping and signs, and to repair damage to the speed hump caused by low slung vehicles, trailers, etc. This will provide an order-of-magnitude estimate of the installation and maintenance costs to be expected if the City elects to begin installation of speed humps. The costs will be refined as we complete the first few installations. If you require further information, please let me know. r e l i m i n a r y List of Potential Speed Hump Locations Subdivision Street Length Total No. Study Installation Total Annual Of Humps Cost Cost Installation Maintenance (feet) Cost Cost _ Cross Creek Bridge Creek Boulevard 2800 9 $400 $9,000 $9,400 $1,350 Reflections Sparkling Water 3300 10 $400 $10,000 $10,400 $1,500 Waterside New Victor Road 1800 5 _ $400 $5,000 $5,400 $750 Cullens Court 2200 7 $400 $7,000 $7,400 $1,050 Richfield Springfield 1500 4 $400 $4,000 $4,400 $600 Coventry Coventry Boulevard 2000 6 $400 $6,000 $6,400 $900 Parkside Dovetail Drive 1500 4 $400 $4,000 $4,400 $600 Forest Oaks !son Lane 1800 5 _ $400 $5,000 _ $5,400 $750 Prairie Lake Boulevard 3400 11 $400 $11,000 $11,400 $1,650 Sawmill Sawmill Boulevard 3400 11 $400 $11,000 $11,400 $1,650 Lumberjack 1700 5 $400 $5,000 $5,400 $750 Log Wagon 2100 6 $400 $6,000 $6,400 $900 Mill Stream 3000 9 $400 $9,000 $9,400 $1,350 Timberridge Trail 2000 6 $400 $6,000 $6,400 $900 Temple Grove Greywall Avenue 2600 8 $400 $8,000 $8,400 $1,200 Silver Bend Cassingham 2600 8 , $400 $8,000 $8,400 $1,200 Alclobe 3000 9 $400 $9,000 $9,400 $1,350 Bexley 600 1 $400 $1,000 $1,400 $150 Silver Glen Sterling Lake 1000 3 _ $400 $3,000 $3,400 $450 Forest Crest 1000 3 $400 _ $3,000 $3,400 $450 _ Lake Olympia Estates Olympus/Adriatic 2500 8 $400 $8,000 $8,400 $1,200 Olympia Cove Hawthorne Cove 1900 6 $400 _ $6,000 $6,400 $900 Hammocks Hammocks Drive 1400 4 $400 $4,000 $4,400 $600 Twin Lakes Manor Little Spring Hill 3500 11 $400 $11,000 $11,400 $1,650 Russell 3100 10 $400 $10,000 $10,400 $1,500 Amber Ridge Ucaria 1100 3 $400 $3,000 $3,400 $450 Satin Leaf 1500 4 $400 $4,000 $4,400 $600 Twin Lake Forest Nicole 3000 9 $400 $9,000 $9,400 $1,350 Marlene 3000 9 $400 $9,000 $9,400 $1,350 Peach lake Manor Lady 3000 9 $400 $9,000 $9,400 $1,350 Mona 2000 6 $400 $6,000 $6,400 $900 Doreen 1500 4 , $400 $4,000 $4,400 $600 Lake Shore Gardens East Lakeshore Drive 3100 10 $400 $10,000 $10,400 $1,500 Vandergrift 1500 4 $400 $4,000 $4,400 $600 Stinnett 1100 3 $400 $3,000 $3,400 5450 Prima Vista Sabinal 1500 4 $400 $4,000 $4,400 $600 Grand Total $248,400 $35,100 PROPOSED CITY OF OCOEE SPEED HUMP PROGRAM Speed humps will only be considered on roadways which: are local residential streets and/or collector roads with a minimum average daily traffic count of 800 vehicles/day and a maximum of 3,000 vehicles/day. have a posted speed limit of 30 mph or less. have an observed 85th percentile speed greater than 35 mph. have a maximum width of 24 feet. The process for obtaining approval for speed hump installation is as follows: 1. Residents should submit a petition signed by at least 66% of the homeowners within a subdivision or 90% of the homeowners fronting on a particular roadway to the Engineering Department. 2. Upon receipt of the petition, the Engineering Department will conduct a traffic study to determine if traffic conditions support the installation of speed humps. 3. If traffic conditions support the installation of speed humps, a public information meeting will be held to present the results of the traffic study, provide a preliminary design and cost estimate, and to give the affected residents an opportunity to provide input. 4. If the feedback received from residents at the public information meeting is generally favorable, a ballot will be mailed to each property owner to vote "for" or "against" the establishment of a special assessment to fund the installation of speed humps. The special assessment would be a tax assessment to property owners in the subdivision located on the roadway(s) where speed humps are proposed. The amount of the assessment is determined by dividing the total project cost by the number of benefiting property owners. The total project cost will be based on the cost of construction administrative costs. 5. If 66% of the returned ballots are in favor of the speed hump installation, the special assessment is scheduled for a public hearing before the Board of City Commissioners. The Board of City Commissions will make the final decision on the establishment of the special assessment. 6. If the Board of City Commissioners approves the special assessment, the speed humps will be scheduled for installation by the Public Works Department. The Seminole County speed hump design (3" high x 22' long) will be utilized.
