City of Plant CityTechnical Service Manual

___________________ Brett J. Gocka, P.E.

City Engineer

Forward

The procedures and provisions set forth in this manual shall apply to any development project, lot, parcel or tract of land within the City limits. These procedures and provisions were developed based upon the latest technical standards from the Florida Department of Transportation, American Association of State Highway and Transportation Officials, Southwest Florida Water Management District, State of Florida Department of Environmental Protection, and the American Society of Civil Engineers.

These standards represent minimum standards for development required to protect the public health, safety and welfare of the citizens of the City of Plant City.

This manual is not meant to be totally restrictive, nor represent the only acceptable method of design. The purpose is only to provide minimum acceptable standards of construction and promote uniformity. The requirements should be reviewed annually to provide consistency with State and Federal requirements.

It is recognized that these standards will not be applicable to every situation that may arise on a particular project. It is also recognized that all specific design or construction problems may not be recognized in the review of the project prior to the construction approval. The City Engineer may make modifications to these standards where the application of the standards to a specific situation will result in an unusual and unreasonable hardship; provided however, that the City Engineer determines that such modification is inconformity with the spirit and intent of applicable ordinances

Chapter 2

A) Permits

1. Upon approval of the application for construction, the City Engineering Department shall issue a permit for construction. The duration of the permit shall not be greater than 5 years.

2. The permit shall be construed as a license to proceed with the work as approved and not as authority to violate, cancel, alter or set aside any of the provisions of this document or City Ordinance, nor shall issuance of a permit prevent the Building Official or City Engineer from thereafter requiring a correction of errors in plans, construction, or violations of this code. Every permit shall become invalid unless the work authorized commences within (6) six months of issuance, or if the work authorized by such permit is suspended or abandoned for a period of (6) six months after the time the work is commenced.

3. The permit may be extended for two (2) time extensions not more than ninety (90) days each provided the total time including any stoppages does not exceed five (5) years. All extensions shall be submitted in writing along with a justifiable cause to the City Engineer and Building Official.

4. For the purposes of this section the following definitions shall apply:

a. Commenced shall mean the installation of utilities.

b. Abandoned shall mean no work has been preformed on site for a period of 96 hours or an approved foundation inspection has not been performed.

5. No construction may commence until plans have been approved by the City Engineer and a preconstruction meeting held (requirement maybe waived by City Engineer).

a. It shall be the responsibility of the developer/owner to coordinate all utilities concerning the proposed development. All utilities shall have been provided a copy of the approved construction plans prior to the preconstruction meeting. Further it shall be the developers responsibility to coordinate utility representatives at the preconstruction meeting. The following utility representatives shall be notified, Tampa Electric Company, local gas utility, Brighthouse, and Verizon.

b. The developer shall provide 6 sets of final plans for construction at the preconstruction meeting. These plans are for distribution to the contractor, developer and engineer of record.

c. The engineer of record and the developer shall be in attendance at the preconstruction meeting. If the engineer of record is not in attendance the City may elect to cancel the preconstruction meeting and reschedule the meeting at a time when the engineer of record may be in attendance.

6. Prior to construction it shall be the contractors responsibility to notify Sunshine State One-Call by dialing 1-800-432-4770 at least 72 hours prior to the start of work.

7. If any work is proposed to take place along any or impacting any Florida Department of Transportation right of way. Separate notification of work commencement must be made to the Florida Department of Transportation local office.

8. Preliminary ditching, clearing and grubbing, and earth moving incidental to the site preparation may be performed with approval of the City Engineer prior to construction plan approval. However, no impacts to wetlands, floodplains and drainage features shall be authorized prior to construction plan approval.

9. Bonding required as part of final plat approval must be secured prior to any impacts to the proposed site and may be used for restoration in the event the project is not approved or the site is not constructed.

10. Any land alteration which takes place prior to construction plan approval must be approved by the City Engineer.

B) Approved Plans

1, All approved plans shall be stamped by the Engineering Department. Plans not stamped shall not be used for construction.

2. The contractor shall maintain an approved set of project plans on site at all times during the course of construction from the first day of the project until final acceptance of the project. These plans are for the use of all contractors, sub-contractors, vendors and City personnel during construction and must be available for their use in the performance of inspections. Failure to comply with this requirement is a breach of the permit requirements and is justification for suspension of the work and\or revocation of the permit by the City Engineer.

3. Revisions to the approved plans by the owner\contractor shall be submitted to the City of Plant City Engineering Department and all applicable government agencies for approval prior to construction of the revision. Non-compliance will cause the revisions to be null and void and will result in non-acceptance of the work in place. Any and all revisions to the approved plans shall be submitted by the engineer of record to the City Engineer and approval obtained prior to implementation of the revisions. It is not the policy of the Engineering Department to suspend work due to revisions of the plans resulting from varying field conditions, field changes due to conflicts with existing facilities, or other normal occurances. However it is the sole responsibility of the contractor\owner\developer to submit revised plans to the Engineering Department for approval.

C) Shop Drawings

1. Shop drawings for all materials to be accepted by the City shall be approved by the City. The contractor shall submit shop drawings approved by the engineer of record for approval by the City.

2. No materials shall be placed on site that have been reviewed and approved by the City of Plant City.

D) Final Acceptance

1. The developer shall request in writing that the development is complete and ready to be accepted by the City. The City shall inspect the site and determine completeness. Acceptance of the project is based upon the projects conformance with the approved plans. If the City finds all improvements have been completed then the developer shall submit a warranty bond that is 10% of the original bonded amount. Construction not conforming to the approved plans will not be accepted until all revisions are approved by the City of Plant City and all other appropriate governmental agencies.

2. In order to avoid close out delays the following items must be submitted prior to scheduling a final inspection:

a. As built drawings and Autocad filesb. Payment of any inspection fee’sc. Letter clearing any notice to owner issuesd. Itemized construction costs e. Engineer certificationsf. Health Department clearanceg. FDEP clearance for wastewater collection systemh. All test results submitted to the Engineering Department

3. Upon completion of a final inspection a punch list of items shall be generated and delivered to the owner and\or contractor. The City will not accept the project until all punch list items have been resolved to the City Engineer’s satisfaction.

4 Prior to acceptance of the improvements, the engineer of record shall supply as-built drawings in accordance with the City as-built drawing requirements indicated in this manual.

5 The City of Plant City shall have the right to inspect and approve materials and/or phases of work. Final inspection and acceptance of work by the City of Plant City shall be obtained in writing prior to acceptance of the improvements by the City.

6 No certificate of occupancy shall be issued until the project has been accepted by the City of Plant City.

Chapter 3

A) Inspection and Certification

Approval of construction plans by the City in no way constitutes a waiver of health and safety standards nor Federal and State laws. The health and safety of the citizens of Plant City is a major concern to the City and takes precedence over any of the approved plans and/or agreements that may be in effect concerning the project.

1. The engineer of record shall be responsible for the inspection during construction to ensure that the project is constructed in accordance with the approved plans and specifications.

2. The City inspector shall determine the time, location and sampling technique for all samples taken in the field. The sampling schedule listed below shall be used to determine field testing requirements.

3. The City inspector does not have the authority to halt construction of a project. Any project stoppages shall be noticed by the City Engineer to the contractor and developer.

Chapter 4

A) Plats

Prior to approval of the final plat, the applicant will have received final construction plan approval and have submitted an approved bond for the development. The purpose of the review and approval of the construction plans prior to final plat approval is to satisfy the design and specification requirements for construction.

The owner of property to be platted must provide an easement or dedication of all property needed for the construction of streets, thoroughfares, alleys, sidewalks, storm drainage facilities, floodways, water lines, wastewater lines and other utilities, and any other property necessary to serve the plat and to implement the requirements of this manual. Dedications shown on plats are irrevocable offers to dedicate the property shown. Once the dedication is made it may be accepted by an action by the City Commission.

No improvements shall be accepted until they are constructed according to the approved plans, details, and specifications, and record in the office of the county clerk.

Streets and the percentage of right of way to be dedicated required for streets is as follows:

1. When the full right of way width of a street is contained within the boundaries of the proposed plat, the entire required right of way contained within the boundaries of the plat must be dedicated for public subdivisions.

2. When a thoroughfare is along the perimeter of a proposed plat, sufficient right of way must be dedicated to provide one half of the thoroughfare plan requirement, measured from the centerline of the existing right of way or, if there is no existing right of way, the proposed right of way as determined by the City Engineer. If the property on the side of the thoroughfare opposite the property to be platted is railroad right of way or a utility or floodway easement, or if some physical or topographical condition makes the property on that side of the street undesirable for street right of way, the City Engineer may require additional right of way.

3. If a substandard right of way exists along the perimeter of a proposed plat and the plat includes property on both sides of the right of way the applicant will be required to provide sufficient right of way to meet the proposed intended use.

Corner clips or sight easements may be required as determined by the City Engineer.

All floodways shall be dedicated to the City.

The following dedication language is typical for subdivisions where all streets are to be maintained by the City.

1. Subdivision plats by no means represent a determination whether properties will or will not flood. Land within the boundaries of this plat may or may not be subject to flooding. The City of Plant City Engineering Department may have further information regarding flooding and restrictions on development.

2. This plat as recorded in its graphic form, is the official depiction of the subdivided lands described herein and will in no circumstances be supplanted in authority by any other graphic or digital form of the plat. There may be additional restrictions that are not recorded on this plat that may be found in the public records of Hillsborough County.

3. Drainage easements shall not contain permanent improvements, including but not limited to sidewalks, driveways, impervious surfaces, patios, decks, pools, air conditioners, structures, utility sheds, poles, fences, sprinkler systems, trees, shrubs, hedges, and landsc |andscaping paing plants other than grass, except for landscaping of stormwater detention and retention ponds as required by the City.

4. Side lot drainage easements shall be maintained by the individual lot owners.

5. Rear lot drainage easements (retention and detention ponds) shall be maintained by the homeowners association.

6. Rear lot drainage easements (swales) shall be maintained by the individual lot owners.

B) Plats Containing Private Roads

1. The private roads shown as tracts XXX are not dedicated to the public, but are hereby reserved by the owner for conveyance to a Homeowner’s Association, Community Development District, or other custodial and maintenance entity subsequent to the recording of this plat, for the benefit of the lot owners within the subdivision, as access for ingress and egress of lot owners and their future, of xxxxx subdivision.

2. Owner hereby dedicates to the City of Plant City and all providers of emergency, fire emergency, emergency medical, mail, package delivery, solid waste, sanitation, water, and reclaim utilities, and other similar governmental and quasi-governmental services, an non-exclusive access easement over and across the private roads and rights of way within tract xxx as shown herein for ingress and egress for the performance of their official duties.

C) Bonds, Security and Letters of Credit

1. Subdivision Construction

a. A bond or letter of credit in the amount of 110% of the total project cost will be required prior to the issuance of a final plat. While a bond is acceptable, the preferred security instrument is a letter of credit. The City Engineer shall review the bond/letter of credit and determine if the proposed amount reflects the actual construction costs in the event of default by the developer. All bonds/letters of credit should be submitted by the developer of the proposed subdivision. Other persons providing the security, such as contractors, may be accepted on a case by case basis. The term of the bond shall be the proposed construction time but generally should not exceed 1 year.

b. Private developments shall bond all utilities dedicated to the City, in addition all stormwater improvements, roadways and all ancillary and other items as deemed necessary by the City Engineer.

2. Term

a. The bond must cover the length of time during construction. This construction time is to be evaluated by the City Engineer as proposed by the Engineer of Record. Construction time generally should not exceed 1 year. On phased development, the developer may elect to submit one bond/letter of credit for all phases to be constructed. However, the City prefers that each phase meet separate bond/letter of credit requirements.

b The term of a subdivision warranty bond/letter of credit shall be 13 months from the date of acceptance by the City. The amount of the warranty bond shall be a minimum of 10% of the original construction bond/letter amount. The developer may request the reduced amount upon acceptance of the subdivision by the City. This provides the City with a 13 month warranty period for evaluation/repair of the improvements

D) Right of Way Security

1. Construction within the City right of way will require the submission of security to the City to secure restoration of the proposed work. While the security is primarily to secure the restoration of the right of way. The City may elect that the contractor provide security for the construction. The City will require that the security instrument be for a term to complete all work. No warranty period is required.

E) Other Security

1. The City may require other security as it deems necessary to secure construction and/or restoration. All security vehicles i.e. bonds, letters of credit, certificate of deposit, checks, etc., shall be evaluated by the City Engineer and City Attorney as to appropriateness. The City may reject any security vehicle that it feels does not reasonably provide the security necessary to meet the goal of the vehicle.

F) Work within FDOT right of way

1. The City may require at its discretion a bond or letter of credit for any work done on a Florida Department of Transportation right of way where the City is the applicant. The term and amount of the bond or letter of credit shall be at the discretion of the City Engineer but, shall not be less than 6 months and $25,000.

2. Any failure shall be repaired by the developer at the direction of the City Engineer within five working days unless the urgency of the problem requires an immediate response. In such case the City may take any corrective actions necessary and shall be reimbursed by the developer for all expenses.

G__CSX

1. Applicants requiring use of CSX rights of way in which the City is required to be the applicant shall reimburse the City for all security, licensing, insurance, bonds and all costs associated with acquiring and maintaining the permit.

H) Default

1. Upon default by the developer to take corrective the City Commission, City Engineer or other applicable public body may exercise it rights under the security upon (10) ten days written notice by certified mail to the parties to the instrument.

Chapter 5

A) Accepted City Materials

Specific materials are listed under each appropriate chapter of this manual. Generally the following materials are accepted for the proposed application:

1. SDR 26 green pvc pipe for sanitary sewer applications2. C 900 DR 14 for sanitary sewer forcemains3. Concrete pipe and inlets in accordance with FDOT specifications for stormwater systems4. Ductile iron pipe class 51 for potable water.5. Concrete manholes in accordance with sanitary sewers as listed in the standard details6. C-900 “purple” DR 18 for reclaimed water service.

This list is not intended to be totally inclusive. The City will accept proposals for alternate materials which will be evaluated on a case by case basis and added to the appropriate section of this manual.

Where a certain manufacturer is specified for a particular piece of equipment, non specified equals may be approved by the City Engineer after submittal of a request in writing and accompanied by supporting documentation.

Chapter 6

A) Clearing and Grubbing

1. Clearing and grubbing shall consists of removal and disposal of all deleterious materials including soil, roots, trees and brush. Removal of foundations, septic tanks, piping and wells shall be in accordance with appropriate regulations for removal and closure of tanks and wells

2. All on site wells shall be closed in accordance with Southwest Florida Water Management District rules and regulations and verification of closure shall be submitted along with the applicants permit application.

3. All materials shall be disposed of off site. No deleterious materials shall be buried on site, used in pond bottoms or for pond construction

B) Site Cleanup

1. The construction site shall be maintained by the contractor in a state of cleanliness for the health and safety of persons working on, visiting the site or living adjacent to the construction site. Site cleanliness shall not be limited to the on-site conditions.

Disposal of all material shall be in accordance with City, State and Federal regulations.

2. All portions of the project open to the public shall be fenced, barricaded and otherwise protected from all construction activities through whatever means acceptable to the City.

C) Erosion Control

1. An erosion control plan with details must be submitted prior to any activity on site and be incorporated into the final design plans. The plan must show considerations for all types of erosion including water borne and air borne particles that shall be retained on site. In all cases the Developer shall be ultimately responsible for the success of the erosion control plan and shall provide or direct his contractor to provide sufficient controls to protect the general public and their properties from the hazards of erosion including installation of track pads for vehicles exiting the site onto public roadways. Materials which have migrated off site shall be removed immediately by an approved method and spoils disposed of in accordance with all State, local, and Federal rules and regulations.

2. Seeding, mulching, sodding and/or other acceptable methods shall be used to prevent erosion during all construction activities. The developer shall be required to maintain curbs and gutters free of accumulations of sand and earth. Temporary silt basins may be required during construction. Maintenance of the basins shall be provided by the developer until final inspection is complete.

3. In all instances no excavated material shall be stockpiled in such a manner as to direct stormwater runoff directly off the project site or into any adjacent water body or stormwater collection facility. Inlets and catch basins shall be protected from sediment laden storm runoff until the completion of all construction

operations that may contribute sediment to the inlet.

4. The City may require that the stormwater conveyance system be cleaned and televised prior to acceptance by the City.

Chapter 7

A) Minimum Design Criteria

1. A legal description must be submitted identifying the property served, easements and dedications.

2. The applicant shall provide a design which includes an analysis of the existing infrastructure capacity and condition in the area, including width of right of way and pavement, street lighting, sidewalks, signals, water, wastewater, and reclaim water service, fire protection, stormwater management and solid waste collection. The design shall address all noted level of service defiencies.

3. In making connections to the City system the developer will likely need to extend/construct off site utilities. The developer is financially responsible for the construction of off site utilities to meet the minimum requirements for development even if these requirements have capacity to or are positioned in a location to serve other properties.

4. The developer is responsible for the design, permitting, and construction of the minimum requirements for development including any upsizing or extensions required by the City.

5. The City Engineer is the final determiner of the size of on-site and off-site utilities and of the configuration of the water, sewer and reclaim system necessary to provide service to the project.

6. The developer is responsible for meeting the required looping requirements of the City as determined by the City Engineer.

7. Water line looping shall be required at a minimum for all residential subdivisions and critical facilities.

8. The developer is responsible for extending/placing on site utilities in a manner as requested by the City Engineer to position the City to provide service to other properties. The City Engineer is the final determiner of the location and configuration of on-site and off-site piping in a manner that best serves the City.

9. Determination of whether or not on-site utilities will be public or private will be determined by the City Engineer, however private water systems are allowed only when all parts of the project property will be forever served by one water meter and possibly one irrigation meter.

10. The City will not serve multiple customers through private, shared or third-party facilities. Each customer must own, have control of and be responsible for the facilities between the City’s point of service and the building or other usage location. This includes water service lines, sewer service connections and reclaim water service.

E) Defintions and Calculations

Urban: Roadway meeting the general criteria of an urban roadway includes curb and gutter.

Rural: Roadway without curb and gutter usually has roadside ditches to route roadway runoff.

Average Annual Daily Traffic (AADT): The total volume passing a point or segment of a road facility, in both directions, during a 24-hour period. It is commonly obtained during a given time period, in whole days greater than one day and less than one year, divided by the number of days in that time period. The volume is then adjusted for seasonal variations using the Seasonal Adjustment Factor.

Estimated K Factor (Peak-to-Daily): The ratio of peak hour traffic to daily traffic. The K Factor allows the conversion from a peak hour volume to a daily volume and the reverse. Table 1 presents an example calculation of the K Factor (as presented in the FDOT 1995 LOS Manual).

* 1998 Seasonal Factors were used due to the absence of published 1999 Seasonal Factors

Directional Distribution Factor (D Factor): This factor accounts for the directional distribution of traffic. It is used to convert peak hour traffic to directional peak hour traffic. Table 2 illustrates how the D Factor is calculated:

Directional PM Peak: The traffic volume for the peak hour in the predominant direction of flow, in vehicles per hour: PM DIR PEAK = (AADT) (K Factor) (D Factor)

K or Design Hour Factor: The ratio of design hour traffic to average annual daily traffic. The K-100 factor allows the conversion from a peak hour volume to a daily volume. Within urbanized areas the K-factor for the 100th hour is generally around 0.09. Table 2 is an example of a K-100 calculation:

1. No public gravity sewer conveying raw wastewater shall be less than 8 inches in diameter.

2. All sanitary sewers and forcemains shall be installed with a minimum of 36 inches of cover.

3. All sewers shall be designed and constructed to give mean velocities, when flowing full, of not less than 2.0 feet per second, based on Manning’s formula using and “n” value of 0.013. The following are the recommended minimum slopes which should be provided; however, slopes greater than these are desirable.

Minimum Slope in FeetNominal Sewer Size Per 100 Feet

8 inch 0.40

10 inch 0.28

12 inch 0.22

14 inch 0.17

15 inch 0.15

16 inch 0.14

18 inch 0.12

21 inch 0.10

24 inch 0.08

27 inch 0.067

30 inch 0.058

33 inch 0.052

36 inch 0.046

39 inch 0.041

42 inch 0.037

4. Slopes slightly less than those recommended for the 2.0 feet per second velocity, when flowing full, may be permitted. Such decreased slopes may be considered where the depth of flow will be 0.3 of the diameter or greater for design average flow.

5. The pipe diameter and slope shall be selected to obtain the greatest practical velocities to minimize settling problems. Oversize sewers will not be approved to justify using flatter slopes. If the proposed slope is less than the minimum slope of the smallest pipe which can accommodate the design peak hourly flow, the actual depths and velocities at minimum, average, and design maximum day and peak hourly flow for each design section of the sewer shall be calculated by the design engineer and be included with the plans.

6. Sewers shall be laid with uniform slope between manholes. Straight alignment shall be checked by either using a laser beam or lamping.

7. Where velocities greater than 15 feet per second are attained, special provision shall be made to protect against displacement by erosion and impact.

8. Sewers on 20 percent slopes or greater shall be anchored securely with concrete, or equal, anchors spaced as follows:

a. Not over 36 feet center to center on grades 20 percent and up to 35 percent;b. Not over 24 feet center to center on grades 35 percent and up to 50 percent; c. Not over 16 feet center to center on grades 50 percent and over.

9. When a smaller sewer joins a large one, the invert of the larger sewer should be lowered sufficiently to maintain the same energy gradient. An approximate method for securing these results is to place the 0.8 depth point of both sewers at the same elevation.

10. Sanitary sewer systems shall be designed by a professional engineer licensed by the State of Florida. The piping systems and all component parts shall be complete, comply with the provisions of the specifications and all engineering drawings, and must receive the final approval of the Engineer; and furnished and installed in accordance with the rules, regulations, and requirements of the following:

The technician shall have the capability of controlling the movement of the television camera, adjusting the brilliance of the built-in lighting system and changing the focus of the television camera by remote control.

The sewer lines shall be internally cleaned prior to televising as previously specified. Any debris, grease or other material causing a blocking of the lens preventing proper viewing of the sewer shall be removed.

After thoroughly cleaning the sewer and just prior to televising, there shall be a 100 gallon flush of clean water introduced to the up stream manhole. Time will be allowed for the water to stop flowing before televising begins.

The camera shall be turned on and a slow, visual inspection shall be made of the manhole corbel, walls and pipe connections, with proper audio identification of conditions, defects and orientation. The camera shall be placed in the manhole invert of the line section to be inspected and slowly positioned to a spot no greater than six (6) feet from the start of pipe so as to position the cable roller assemblies. The point of reference for all distance measurements shall be a specific object within one to two feet in front of the camera lens, said object to be mutually agreed upon between the Contractor and the Engineer. The footage indicator will be set at zero for the center of the staring manhole and shall record the camera's position to the aforementioned object within the pipe. This initial operation shall be continuously recorded by the camera and all findings recorded in the log. At the ending manhole, the camera shall continue to record the pipe and manhole condition as in the starting manhole. The footage measurement shall end when the center of ending line manhole is reached. Any horizontal differences along the section between the center of the manhole frame and the center of the manhole base for either manhole shall be measured and recorded.

The television camera shall be pulled through the sewer lines by use of a mechanical or power-driven winch. It shall be pulled at a rate which will allow the inspector at the monitor to completely and thoroughly inspect the sewer line but never faster than 30 feet per minute. At every defect, lateral service connection or unusual condition within the pipe, the camera shall be stopped for proper observation.

If there is an interference in the sewer line that will not allow the television camera to pass, then the camera shall be backed out of the line and an attempt shall be made to televise the line from the manhole at the other end. If the entire length of the sewer line cannot be televised because of two or more obstructions, then the Engineer shall be notified and a determination of how to proceed shall be made. Should the camera or other equipment become lodged within the pipe or manhole, the Contractor shall take whatever steps are necessary to quickly remove the equipment and restore any damaged material to approved condition at no cost to the Owner.

Video tapes shall be made upon the request of the Engineer. When requested, the video tape shall be made continuously as the camera is turned on and pulled through the line. Each tape shall be of the grade and quality best adapted to show the sewer in sharp detail, and shall be of 1/2 inch VHS cassette type, minimum play time 4 hours, or as required by the Owner. Each tape shall be numbered, dated and identified with sewer line station and location and an index of all tapes prepared referencing project, date, Contractor, mini-system, line section and tape counter number and be approved by the Engineer before accepting same. The tape shall become the property of the City.

Audio and visual identification of the manholes,line section, street, mini-system and other pertinent information as required by the Engineer shall be given at the beginning of each line section. Distances to all defects or other recorded points shall be given by audio description as well as the technician's observations of pipe condition, potential defects, leakage rates and all other previously described items. No outside noise, conversation or nonpertinent comments will be allowed to be recorded.

Any electrical service required by the Contractor for televising sewer lines shall be provided for by the Contractor.

The Contractor shall furnish all equipment required for taking photographs of the views which appear on the monitor. Photographs shall be taken at the discretion of the Engineer to show bad joints, cracks, and any other problem spots. These photographs are to supplement the video tape recordings and all costs involved in photography shall be considered incidental to the work.

Approval of the installation cleaning, television inspection, or video tapes will be made only after a complete review of all submitted logs and video tapes for the appropriate line sections. Should the Engineer determine, upon review, that the data submitted is inadequate due to log errors or omissions, improper or insufficient cleaning, equipment malfunctions, poor video quality, such as breaks in the continuous recording or poor or inadequate audio recording, no sound, no picture, poor photography results, incorrect distance measurements or other problems resulting in inaccurate or incomplete data, the Contractor shall schedule whatever operations are necessary to redo completely the television inspection, with any required cleaning, for the particular line section. The Contractor shall perform the rework within five (5) working days after receipt of the written notification by the Engineer.

Any retelevising of the lines due to poor cleaning, poor video tape quality, or insufficient logs as determined by the Engineer shall be at no additional expense to the Owner.

Appendix A

RESIDENTIAL TRAFFIC CALMING CRITERIA & PROCEDURES

The following procedure shall be used when traffic calming is requested on City streets. This procedure outlines the orderly tasks to be followed to determine the appropriate traffic calming measure.

A) Initiate a neighborhood traffic study:

2. An association or neighborhood representative should contact the City of Plant City Public Works Department to request traffic calming.

3. Verify that at least 65% of the community supports traffic calming in the community.4. The City shall only evaluate local streets for traffic calming with a typical volume of

500-3000 AADT. 5. No emergency or transit agencies have objections.6. No diversion to other streets.7. Staff collects and analyzes data about the traffic issues that have been identified and

presents the findings to the neighborhood representative.

If the criteria for traffic calming measures are met, then Type 1 option alternatives will be examined. These are as follows:

Type 1 Options

Traffic Control Signage, Regulation Signage Striping centerline, edgelines, stop bars Request increased police presence Speed alert program or radar trailer program

A follow-up study will be conducted within 30 days after Type 1 options are installed/performed. If Type 1 options are ineffective at controlling the undesired traffic conditions, then Type 2 options will be examined. Street segments that do not meet the qualification are not further considered for traffic calming.

To be eligible for physical traffic calming measures, a street must meet the following qualifications:

Criteria for Qualification Installation of Traffic Calming Measures:

It must be classified as a Local residential street abutting land use is at least 85% residential. It cannot be a designated fire response route or transit route. It cannot be more than two travel lanes wide.

The street surface must be to current City standards, and maintained by the City. Installation of a traffic calming measure will not divert traffic to another street. Traffic calming measure produces no liability and is compliant with State law.

Street must meet at least 1, 2 ,3 & 4 of the following:(Number’s 5 or 6 may be substituted for #3)

1. 500 minimum vehicles per day 3000 maximum2. 1000’ minimum street length3. 85% of vehicles exceeding the speed limit4. A minimum of 65% of residents must give approval5. A minimum of 3 correctable accidents in 12 months6. A minimum of 25% cut through traffic

Prior to installing any Type 2 option alternative, a majority of homeowners must concur with the recommended actions. A public meeting will be held to report on the survey results, identify the issues, and discuss possible solutions, including alternative designs. A “working group” may be formed at this meeting, consisting of people who want to take a more active role in developing the project. Meeting participants give staff ideas about possible solutions they would like to see pursued.

Type 2 options for consideration will be:

Crosswalk Refuge Choker Chicane Raised Sidewalk Center Island Narrowing Traffic Circle Textured Pavement

Once all the criteria have been met, and a type 2 option selected a public hearing before the City Commission is held. If approved, and with adequate funding the traffic calming plan can then be implemented.
