SUGGESTED STEPS FOR A DEVELOPER OF A SUBDIVISION

 

Throughout the following process, the owner/developer is strongly encouraged to personally participate in consultations and meetings regarding the development.

 

1.      Confer with the Planning Commission and its Staff Planner to become thoroughly familiar with the subdivision requirements, the major road plan and other public improvements which might affect the area to be subdivided.

 

2.      Have preliminary sketch plat prepared by a reputable state-licensed surveyor.

 

3.      Discuss preliminary plat with staff representative. This pre application review by a trained land planner may save the subdivider time and costly revisions as well as possible savings through better design.

 

4.      If development will use individual septic tanks, submit plat to Tennessee Department of Environment and Conservation, which may place restrictions on number, size, and use of lots. The timing of approval by the McMinnville Regional Planning Commission is dependent on the Tennessee Department of Environment and Conservation results.

 

5.      Submit required copies of the preliminary plat to the Planning Commission in advance of its regular monthly meeting.

 

6.      See city engineer or designated approving agent(s) for street and utility specifications. Obtain Tennessee Department of Environment and Conservation approval of water and sewer plans and submit signed plans to the McMinnville Regional Planning Commission.

 

7.      After preliminary plat approval has been granted, develop subdivision according to preliminary plat and the required modifications, if any. Install improvements.

 

8.      Prepare final plat.

 

9.      Obtain signatures on certificates from street and utility officials certifying that improvements have been made (or that a financial guarantee has been established).

 

10.       Submit final plat to the Planning Commission for approval. When approved, the Planning Commission secretary will sign the certificate of approval for recording.

 

11.       The subdivider records the plat with the county Register of Deeds' office and is now ready to sell the lots.


 


SUBDIVISION REGULATIONS

Of

The McMinnville Regional Planning Commission

 

McMinnville, Tennessee

 

 

ARTICLE I          GENERAL PROVISIONS

 

A.        Purpose

 

Land subdivision is the first step in the process of community development. Once land has been cut up into streets, lots, and blocks and publicly recorded, the correction of defects is costly and difficult. Subdivision of land sooner or later becomes a public responsibility, in that roads and streets must be maintained and various public services customary to urban areas must be provided. The welfare of the entire community is thereby affected in many important respects. It is therefore in the interest of the public, the developer, and the future owners that subdivisions be conceived, designed and developed in accordance with sound rules and proper minimum standards.

 

The following subdivision regulations guiding the McMinnville, Tennessee, Regional Planning Commission (hereafter referred to as the Planning Commission) are designed to provide for the harmonious development of the regional area; to secure a coordinated layout and adequate provision for traffic, light, air, recreation, transportation, water, drainage, sewer, and other sanitary facilities.

 

B.        Authority

 

These subdivision regulations are adopted under the authority granted by Section 13-3-401 through Section 13-3-411 and Section 13-4-301 through Section 13-4-309 of the Tennessee Code Annotated. The Planning Commission has fulfilled the requirements set forth in these statutes as a prerequisite to the adoption of such regulations, having filed on June 28, 1995 a certified copy of the Major Road Plan in Note Book 18, Page 388 and Cabinet B, Slide 134-A in the office of the Register of Deeds of Warren County, Tennessee.

 

C.        Jurisdiction

 

These regulations shall govern all subdivisions of land within the corporate limits of McMinnville, Tennessee, and its planning region, as now or hereafter established. 

 

Any owner of land within the City of McMinnville or within its planning region wishing to subdivide land shall submit to the Planning Commission a plat of the subdivision according to the procedures outlined in Article II, which plat shall conform to the minimum requirements set forth in Article III. Improvements shall be installed as required by Article III.

a.         The granting of the variance will not be detrimental to the public safety, health, or welfare or injurious to other property;

 

b.         The conditions upon which the request for a variance is based are unique to the property for which the variance is sought and are not applicable generally to other property;

 

c.         Because of the particular physical surroundings, shape or topographical conditions of the specific property involved, a particular hardship to the owner would result, as distinguished from a mere inconvenience, if the strict letter of these regulations are carried out;

 

d.         The variances will not in any manner vary the provisions of the Zoning Code.

 

2.         Conditions: In approving variances, the Planning Commission may require such conditions as will, in its judgment, secure substantially the objectives of the standards or requirements of these regulations.

 

3.         Procedures: A petition for any variance shall be submitted in writing by the subdivider at the time when the preliminary plat is filed for consideration by the Planning Commission.  Said petition shall state fully the grounds for the application.  Each request for a variance shall be specifically applied for in the numerical order of the subdivision regulations.

G.        Separability

 

Should any section, subsection, paragraph or provision of these regulations be held invalid or unenforceable by a court of competent jurisdiction, such decision shall in no way affect the validity of any other provision of these regulations, it being the intention of the McMinnville Regional Planning Commission to adopt each and every provision of these regulations separately.

 

H.        Repeal of Previous Regulations

 

All subdivision regulations previously adopted by the McMinnville Regional Planning Commission are hereby repealed as of the adoption and effective date of these regulations.

 

I.          Amendments

ARTICLE II         PROCEDURE FOR PLAT APPROVAL

 

The procedure for review and approval of a subdivision plat consists of four (4) basic steps.  (1) The initial step is the pre-development conference with the Staff Planner for the Planning Commission for advice and assistance.  (2) The second step is the preparation and submission to the Planning Commission of a Preliminary Plat of the proposed subdivision.  (3) The third step is to construct or install improvements such as streets, fire hydrants and utility lines.  (4) The fourth step is the preparation and submission to the Planning Commission of a Final Plat, together with required certificates.  This Final Plat becomes the instrument to be recorded in the office of the Warren County Register of Deeds when duly signed by the secretary of the Planning Commission.

 

A.        General

 

1.         Any owner of land lying within the area of jurisdiction of the Planning Commission who wishes to divide land into two (2) or more lots, sites, or other divisions requiring any new street or utility construction, or any division of less than five (5) acres for the purpose, whether immediate or future, of sale or building development, or who wishes to resubdivide an existing subdivision lot(s) for this purpose, shall submit a plan of such proposed subdivision to the Planning Commission for approval and shall obtain such approval prior to the filing of his subdivision plat for record and prior to selling or giving a deed for any lot.

 

Any such plat of subdivision shall conform to the minimum standards of design for the subdivision of land as set forth in Article III of these standards and shall be presented in the manner specified in the following sections of this Article. No plat of a subdivision of land within the area of planning jurisdiction shall be filed or recorded by the Register of Deeds without the approval of the Planning Commission as specified herein.

 

2.         In order to secure review and approval by the Planning Commission of a proposed subdivision, the prospective subdivider shall, prior to the making of any street improvements or installations of utilities, meet informally with the Staff Planner for a pre-development conference.  The developer shall then submit to the Planning Commission a preliminary plat, and other required information, as provided in Sections D and E of this Article. On approval of said preliminary plat, the developer may proceed with the construction of improvements as set forth in Article III, and with the preparation of the final plat and other documents required in connection therewith as specified in Sections F and G of this Article.  In no case shall a preliminary plat be presented in sections.

 

3.         Omission of Preliminary Plat

 

            The preliminary plat may be omitted and only a final plat submitted, IF ALL OF THE FOLLOWING CONDITIONS ARE MET:

 

a.         The proposed subdivision does not contain more than five (5) lots, sites, tracts, or divisions.

 

b.         All public improvements as set forth in Article III are already installed. (Any construction, installation, or improvement of public improvements shall require the submission of a preliminary plat.) The Tennessee Department of Environment and Conservation has approved the lots for septic systems, if applicable.

 

c.         The subdivider has consulted informally with the Staff Planner for advice and assistance, and it is agreed upon by the Planning Commission that a preliminary plat is unnecessary prior to submission of the final plat and its formal application for approval.

 

4.         The owner or his authorized representative must be present at preliminary plat review and approval and final plat review and approval. In his absence, the property owner may be represented by his agent or representative who shall present written authorization.

 

5.         No final subdivision plat shall be approved by the Planning Commission or accepted for record by the Warren County Register of Deeds until the required improvements listed shall be constructed in a satisfactory manner and approved by the local approving agent.  In lieu of such prior construction, the Planning Commission may accept certain forms of financial guarantees (See Section G-9 of this Article) in amounts equal to the estimated cost of installation of the required improvements, whereby improvements may be made and utilities installed without cost to the City of McMinnville in the event of default by the subdivider.

 

B.        Filing Fee

 

At the time of the submittal of a preliminary plat for review, or final plat if a preliminary plat is not required, a nonrefundable filing fee of one hundred dollars ($100.00) shall be paid to the City of McMinnville.  Said fee shall be used to help defray the costs of plat review and inspections.            

 

C.        Plat Standards

 

            1.         State Standards Shall Apply

                       

            All plats submitted to the McMinnville Regional Planning Commission for consideration shall meet the accuracy standards for an Urban and Subdivision Survey (Category 1) as established by the Tennessee Board of Examiners for Land Surveyors (January, 1992 Revised).  Said regulations state:

                                                                                   

                        "For Category 1 surveys in Tennessee, the angular error of closure shall not exceed 15 seconds times the square root of the number of angles turned.  The linear error of closure shall not exceed 1 foot per 10,000 feet of perimeter of the lot of the land (1 : 10,000).  When very small lots are encountered, the allowable error shall not exceed 1/10 of a foot of positional accuracy per corner."

 

            All plats shall include a statement by the surveyor regarding the methods used in making the survey and its relative accuracy, as well as the surveyor's seal and signature.

 

            2.         Sheet Format

 

            All preliminary and final plats submitted to the McMinnville Regional Planning Commission for consideration shall be in a format consistent with the example of the acceptable sheet format depicted on Illustration 1 in Appendix A and shall:

 

a.         Be generally drawn to a scale of not less than 1" = 100'. When more than one sheet is required, an index sheet of the same size drawn at an easily read scale shall be filed showing the entire subdivision with the sheets lettered in alphabetical order as a key.

 

                        b.         Be either 18" x 24" or 24" x 36" in size.

 

                        c.         Contain in the lower right-hand corner a standard title block,                                          (See Illustration 2 in Appendix A), which includes:           

                                   

                                    (1)       Name of subdivision

 

                                    (2)       Names, addresses, and phone numbers of developer,                                       surveyor, and engineer (if applicable)

                                   

                                    (3)       Scale of drawing      

 

                                    (4)       Acreage to be subdivided

 

                                    (5)       Number of lots to be created

 

                                    (6)       Appropriate reference(s) to the Warren County Tax                                                         Maps

 

                                    (7)       Date plat was prepared

           

                        d.         Contain in the upper right-hand corner a location map, a                                                graphic scale and an approximate north arrow.

 

D.        Preliminary Plat Requirements

 

            In addition to being prepared to the prescribed format, each Preliminary Plat shall contain the following information as may be appropriate:

 

1.         The location of all existing and proposed property lines, streets, water courses, railroads, sewer lines, water lines, drain pipes, bridges, culverts, and easements for existing utilities (water, sewer, gas, electricity, etc.) or other features.  Existing features shall be distinguished graphically from those which are proposed.

 

2.         The present zoning classification (if any) both of the land to be subdivided and of adjoining lands, the names of adjoining property owners or subdivisions, the name of the applicable water district, and the size of existing water and sewer lines.

 

3.         Plans, prepared by the developer's engineer, of proposed sewer and water systems showing connections to the existing or any proposed utility systems, including line sizes, location of hydrants and manholes. When sewer connections are not accessible, as discussed in Article III, Section H, any land on which an individual sewage disposal system is proposed must be reviewed by the Tennessee Department of Environment and Conservation.

 

4.         The proposed street names, and the location, width, and other dimensions of proposed streets, alleys, easements, parks and other open spaces, reservations, lot lines, and building setback lines.

 

5.         Topographical contours at vertical intervals of not more than five (5) feet.

 

6.         Center line profiles for all proposed streets and, where required by the City Administrator or Public Works Director, cross-sections of proposed streets based on 50 foot stations.

 

7.         Subsurface conditions on the tract, if required by the Planning Commission: location and results of tests made to ascertain subsurface soil, rock, and ground water conditions; depth of ground water unless test pits are dry at a depth of five (5) feet; and location and results of soil percolation tests, if individual sewage disposal systems are proposed.

 

8.         If any portion of the land proposed for subdivision lies within a floodable area, as determined by an official Flood Hazard Boundary Map or Flood Insurance Rate Map, that portion shall be so indicated.

 

9.         A drainage plan showing proposed modifications to the flow of water across the site or to and from adjoining properties.  The City Administrator or Public Works Director may require the submission of more detailed information including, but not limited to, a final grading plan for all or a portion of the site, and calculations describing the existing and proposed volumes of water to be discharged from the site.

 

E.        Procedure for Preliminary Plat Review

 

            The following procedure shall apply for the review of all Preliminary Plats:

 

1.         At least 15 days prior to the meeting at which it is to be considered, the subdivider shall submit to the McMinnville Office of Codes Enforcement eight (8) copies of any required preliminary plat of a proposed subdivision. If necessary the developer should provide copies to the Tennessee Department of Environment and Conservation.   The Office of Codes Enforcement will give copies of the plat to the Staff Planner for review and distribute copies to all applicable utilities and departments (water, sewer, fire, telephone, street, electric, or gas, as necessary).

 

2.         The Staff Planner for the Planning Commission shall review the preliminary plat for conformance with the specifications and standards of these regulations.

 

3.         The preliminary plat shall be presented by the developer or his designated representative to the Planning Commission at its next meeting for a review period not to exceed 30 days.  The  developer should be physically present at the meeting(s) to answer questions and hear suggestions about his proposed development or be represented by an authorized agent as discussed in Article II, Section A(4).

 

4.         Within 30 days after submission of the preliminary plat to the Planning Commission for consideration, the Planning Commission shall approve or disapprove said plat. Failure of the Planning Commission to act on the preliminary plat within the 30 day period will be deemed approval of this plat. If a plat is disapproved, reasons for such disapproval shall be stated in writing. If approved subject to modifications, the nature of the required modifications shall be indicated.

 

5.         If a plat has been disapproved, a new plat may be presented as though no previous plat had been submitted. If a plat has been approved, or approved subject to modifications, and the subdivider desires to make substantial modifications other than those already required by the Planning Commission, a new preliminary plat must be submitted, which is subject to the same regulations and procedures as though no previous plat had been submitted, except that a certification to the effect that the previous plat has been withdrawn must be submitted. If the Tennessee Department of Environment and Conservation rejects any lot(s) or recommends any alteration of lot size or shape, the Planning Commission may require the plat to be resubmitted for preliminary plat review.

 

6.         Two (2) copies of the preliminary plat will be retained in the Planning Commission files, copies shall be retained by the applicable utility departments, and one copy shall be returned to the subdivider with any notations at the time of approval or disapproval and the specific changes, if any, required.

 

7.         The approval of the preliminary plat by the Planning Commission shall not constitute acceptance of any final plat.

 

8.         The approval of the preliminary plat shall terminate unless a final plat based thereon is submitted within one (1) year from the date of such approval; provided, however, that an extension of time can be applied for by the developer and granted by the Planning Commission.  If no work has begun to install improvements and if an approved final plat has not been financially guaranteed, and the McMinnville Regional Subdivision Regulations have changed, the subdivision must meet the new regulations.

 

F.         Final Plat Requirements

 

1.         The final plat shall conform substantially to the approved preliminary plat. Any alterations or deviation from the preliminary plat should be discussed with the Staff Planner to determine if the changes require new preliminary plat review.

 

2.         If the subdivision is to be developed in phases and the final plats submitted as portions or sections of the preliminary plat, the sections must be identified by alphabetical characters, following the name of the subdivision as initially submitted or as approved on preliminary.

 

3.         A final plat will not be acceptable for submission unless it meets all required standards of design, and contains all required information, or contains a written request for a variance for each specific deviation from requirements.

 

4.         In addition to being prepared in the prescribed format, each Final Plat shall contain the following information as may be appropriate:

 

a.         The right-of-way and pavement lines of all streets and roads; the size and location of installed and/or preexisting water and sewer mains; alley lines; hydrant locations; lot lines; building setback lines; any easements for rights-of-way provided for public services, utilities and the disposal of surface water; the limitation and/or dimensions of all easements; lots numbered in numerical order; any areas to be dedicated to public use; and any sites for other than residential use, with notes stating their purpose and limitations.

 

b.         A statement of the restrictions for all easements and right-of-ways indicating the following:

           

(1)       No permanent structure such as a deck, patio, garage, carport or other building shall be erected within the limits of any easement shown on this plat.

 

(2)       No excavation, filling, landscaping or other construction shall be permitted in any drainage easement shown on this plat if such excavation, filling, landscaping or other construction will alter or diminish the flow of water through said easement.

 

(3)       All driveways, entrances, curb cuts or other points of ingress or egress to the lots shown on this plat shall be in accordance with the rules and regulations of the City of McMinnville; contact the Public Works Department for information.

 

(4)       The placing of pipe within or otherwise filling of ditches within the right-of-way shown on this plat is prohibited without the approval of the City of McMinnville; contact the Public Works Department for information.

 

c.         Sufficient data to determine readily and reproduce on the ground the location, bearing and length of every street line, lot line, boundary line, block line, and building line whether curved or straight, and including true north point. This shall include the radius, central angle, and tangent distance for the center line of curved streets and curved property lines that are not the boundary of curved streets.

 

d.         All dimensions to the nearest one-hundredth (100th) of a foot and angles to the nearest 20 seconds.

 

e.         Location and description of all bench marks, monuments and corner markers.

 

f.          The names and locations of adjoining subdivisions and streets and the location and ownership of adjoining unsubdivided property.

 

g.         If any portion of the land being subdivided is subject to flooding or is in a FEMA identified flood hazard area, it shall be indicated on the final plat.

 

h.         If this is a resubdivision of a previously recorded subdivision, provide plat book and page of last subdivision plat being amended.

 

            i.          Standard plat certifications as may be appropriate to the           context of the subdivision (See Article II, Section G (10)             below).

 

G.       Procedure for Final Plat Review

 

           The following procedure shall apply for the review of all Final Plats:

 

1.         Final plats should be submitted at least 15 days prior to the Planning Commission meeting. If the developer has obtained the signatures of utility and road officials because improvements have been completed or were not required, he should provide those utilities with a copy of the plat, and submit four (4) copies to the McMinnville Office of Codes Enforcement.  The submission of the final plat to the Office of Codes Enforcement shall not constitute submission of the final plat for consideration by the Planning Commission.

 

2.         The Staff Planner for the Planning Commission shall review the final plat for conformance with the specifications and standards of these regulations.

3.         The official submission of the final plat to the Planning Commission is considered to be the first Planning Commission meeting at which the plat is presented for consideration, with the developer or his authorized representative present to answer questions and provide information.  The Planning Commission may review the plat for a 30 day period.

 

4.         The Planning Commission shall approve or disapprove the final plat within 30 days after its submission for consideration. Failure of the Planning Commission to act on the final plat within this 30 day period shall be deemed approval of it. If the plat is disapproved, the grounds for disapproval shall be stated upon the records of the Planning Commission.

 

5.         When the plat has been approved by the Planning Commission, the original will be returned to the subdivider with the approval of the Planning Commission certified thereon, for filing with the county register of deeds as the official plat of record; two (2) copies will be retained in the records of the McMinnville Regional Planning Commission and one (1) copy will be returned to the developer for his records.

 

6.         Approval of the final plat by the Planning Commission shall not constitute the acceptance by the public of the dedication of any streets or other public way or ground.

 

7.         The Planning Commission shall require that an accurate map ("as-built" drawings) of all water lines, valves, fire hydrants, sewer lines and appurtenances be supplied by the developer to the City of McMinnville as a condition for final approval of any plat. State law requires that plans and specifications of all water and waste water facilities shall be prepared by a registered engineer and approved by the Tennessee Department of Environment and Conservation.  A copy of such plans shall be forwarded by the developer to the City of McMinnville.

          

8.         Approval of the final plat can not be given until completion and approval of the required improvements. These improvements are to be installed in accordance with Article III. The required improvements must be approved by the person(s) designated by City Administrator and/or a representative of the appropriate utility or road department, and then be reported to the Planning Commission.  The required improvements include:

 

a.         Monuments and iron pins

b.         Storm drainage system

c.         Street grading and paving

d.         Sidewalks (if required)

e.         Water supply system lines and laterals

f.          Sewage collection lines and laterals (if applicable)

g.         Driveway cuts with culverts (homes to be built by developer)

h.         Fire hydrants (if applicable)

i.          Any other improvements that may be required by the Planning Commission

 

9.         Financial Guarantees in Lieu of Improvements

 

a.         Conditions may exist whereby a developer may be unable to install all improvements before requesting final plat approval. In lieu of the installation of all improvements, the Planning Commission may accept one of the following forms of financial guarantees, whereby in the event of default by the developer, improvements and utilities can be made without cost to the city:

 

(1)       The establishment of cash in a bank escrow account in the full amount of the estimated cost of required improvements plus 10% yearly inflation factor.

 

(2)       An Irrevocable Letter of Credit, issued by a Bank or Savings and Loan, signed by two officers, to cover the full amount of the estimated cost of improvements plus 10% yearly inflation factor.

 

(3)       A certified check in the full amount of the estimated cost of required improvements, plus 10% yearly inflation factor.

 

b.         In determining the basic cost of improvements the Planning Commission may use a formula using a base cost per linear foot for each required improvement, that being a cost standard in the construction industry that particular year. The Planning Commission may determine the base cost by receiving information and/or bids from recognized contractors. If the developer provides the bid or estimated cost of improvements, the Planning Commission must determine that the contractor will guarantee the cost for at least the term of the guarantee plus two months.

 

c.         At the time of acceptance of a guarantee, the Planning Commission shall specify the specific length of time before the city would take legal steps to cash it, but this time cannot exceed two (2) years.

 

d.         No financial guarantee shall be partially withdrawn by the developer during the construction period to pay for development costs except in the case of a final payment made after final inspection and approval by the Planning Commission, or except in the case where a developer is postponing binder surface paving on a street until after a winter settling period for the completed and approved gravel base.

 

10.       Certifications (See Appendix B for Forms)

 

In all cases some or all of the following certificates shall be present and signed on the original final plat before the Planning Commission Secretary signs the plat for recording the plat at the Register of Deeds' Office.  The developer shall check with the Staff Planner as to which certificates shall be depicted on the final plat.

 

Form 1) Certificate of Ownership and Dedication-Certification showing that applicant is the land owner and dedicates streets, rights-of-way, and any sites for public use.

 

Form 2) Certificate of Accuracy & Precision-Certification by surveyor of accuracy of survey and plat and placement of monuments.

 

Form 3A) Certificate of General Approval for Installation of Subsurface Sewage Disposal Systems-This certification to be used if any lots will use septic tanks, and must be signed by an appropriate representative of the Tennessee Department of Environment and Conservation before presentation to Planning Commission for final approval.

 

Form 3B) Certificate of Approval of Sewage Collection Facilities-This certification is to be used for any lots connected to or proposed to be connected to McMinnville sewer system. Part (1) pertains to sewer facilities installed, whereas Part (2) pertains to acceptance of a financial guarantee in lieu of improvements.

 

Form 4A) Certificate of Approval of Water Lines-This certification is to be used for any lots where new water lines or hydrants have been (or will be) installed. Part (1) pertains to water facilities installed whereas Part (2) pertains to acceptance of a financial guarantee in lieu of improvements. This would be signed by an official of the applicable water service district.

 

Form 4B) Certification of Existing Water Lines and/or other Utilities-This certification is to be used for any lots served by and connected to previously existing water and/or sewer lines. This would be signed by an official of the applicable utility.

 

Form 5A) Certificate of Streets and Drainage System-This certification is to be used for any lots served by new streets, drainage system, etc., recently installed or to be installed, in conformance to Planning Commission regulations, with signature by applicable official.

 

Form 5B) Certificate of Existing Street(s)-This certification is to be used for a subdivision which does not involve new street construction but which fronts on an existing street. That street may not meet Planning Commission requirements.

 

Form 6) Certificate of Approval for Recording-Certification by Planning Commission Secretary that plat has been approved by the commission. In all cases this certification will be signed only after all other certificates have been signed and after final approval has been granted by the Planning Commission.

 

 

 

H.        Inspections Procedures

 

1.         The developer shall notify the City Administrator, Public Works Director and/or County Road Superintendent and the McMinnville Water/Waste Water Department and/or Utility District Manager when work on streets and/or utilities is to begin and the anticipated schedule for the preparation of subgrade and road base, installation of drainage and underground utilities, and binder surfacing of the road. Since the inspections need to be made periodically during the entire process, communication with the City Administrator, Public Works Director and/or County Road Superintendent and the McMinnville Water/Waste Water Department and/or Utility District Manager are essential to make the process move as smooth as possible.

 

2.         The developer shall notify the City Administrator, Public Works Director and/or County Road Superintendent and the McMinnville Water/Waste Water Department and/or Utility District Manager at least 24 hours in advance of the needed inspection on:

 

a.         Street grading, preparation of subgrade, and installation of the drainage system.

 

b.         Installation and pressure testing of water mains, water stubs, sewer lines, and any other underground utility lines.

 

c.         Pavement base. Inspection includes checking thickness of gravel every 500 feet at random points across width.

 

d.         Prime coat, binder course and drainage system.

 

3.         Throughout the construction period, the City Administrator, Public Works Director and/or County Road Superintendent and the McMinnville Water/Waste Water Department and/or Utility District Manager will keep a log of findings and periodically report the status to the Planning Commission Staff Planner. Problems should be brought to the attention of the Planning Commission immediately.

 

4.         Upon completion of steps a-d listed above, the inspector(s) will submit a written report to the Planning Commission. These inspection reports will become part of the official records of the Planning Commission.

 

5.         If a guarantee is posted by the developer in lieu of required improvements, funds shall not be released until all roads and utilities meet all required standards and the Planning Commission has received written reports to that effect.

 

6.         No improvements will be accepted by the City of McMinnville that have not been inspected and deemed acceptable by the appropriate representatives of the City.

 

 

I.          Warranty of Improvements

 

1.         In addition to the Financial Guarantee in Lieu of Improvements, as well as in the case of the completion of required improvements, the developer shall warranty improvements made under the provisions of these regulations for a period of one (1) year from the date of acceptance by the City of McMinnville.

 

2.         The Warranty of Improvements shall consist of an escrow account, letter of credit, or certified check.

 

3.         The amount of the warranty shall be not less than twenty-five percent (25%) of the cost of the improvements installed under these regulations nor more than $5,000.

 

4.         The Warranty of Improvements shall be submitted to the City of McMinnville prior to the submittal of the subdivision plat for final approval.

 

J.         Recording of Final Plat

 

Upon approval of the final plat and the signing of the appropriate certificates affixed thereto, it shall be the responsibility of the developer to ensure that said plat is placed upon the records of the Register of Deeds' Office of Warren County, Tennessee.

 

K.        Grounds for Denying Plat Approval

 

The McMinnville Regional Planning Commission shall deny approval of any plat submitted to it for review that does not meet or exceed the minimum requirements set forth in these regulations.  In addition, the Planning Commission may deny approval of a plat for the subdivision of land for which:

 

1.         The available water supply is inadequate to serve the anticipated development or the available water supply is inadequate to provide fire protection;

 

2.         The means of ingress and egress is inadequate to carry the vehicular traffic projected to be generated by the proposed subdivision or the means of ingress and egress is inadequate for  use by garbage trucks, fire trucks or other city-owned equipment; or

 

3.         The approval of said plat will in the opinion of the Planning Commission be detrimental to the health and safety of the public.

ARTICLE III        DESIGN AND SPECIFICATIONS

 

A perfectly prepared and recorded subdivision or plat means little to a prospective lot buyer until he can see actual physical transformation of raw acreage into lots suitable for building purposes and human habitation. Improvements by the subdivider spare the community a potential tax liability.

 

A.        Suitability of the Land

 

1.         Land Physically Unsuitable for Subdivision

 

a.         Land where flooding, bad drainage, steep slopes, rock formations, and other such features which may endanger health, life, or property, aggravate erosion, increase public funds for supply and maintenance of services, and

 

b.         Land which other public agencies have investigated and found in the best interest of the public not suitable for the type of platting and development proposed shall not be approved for subdivision unless adequate methods are formulated by the developer for meeting the problems created by subdivision of such land. Such land within any plat shall be set aside for such uses as shall not produce unsatisfactory living conditions.

 

2.         Land Unsuitably Located for Subdivision

 

a.         The Planning Commission shall not approve what it considers to be scattered or premature subdivision of land which would endanger health, safety, or property because of lack of or adverse effect on water supply, schools, proper drainage, good transportation, or other public services or which would necessitate an excessive expenditure of public funds for the supply or maintenance of such services.

 

b.         Land unsuitable for subdividing is also that located in close proximity to potentially hazardous commercial operations which may endanger health, life, or property of the residents of the proposed subdivision.

 

B.        Special Requirements for Floodable Areas

 

1.         The purpose of this section is for the review of subdivision proposals to determine whether such proposals will be reasonably safe from flooding. In order to accomplish this, the following regulations shall apply:

 

2.         Definition of Land Subject to Flooding

 

a.         For the purpose of these regulations, land subject to flooding shall be defined as those areas within the McMinnville Planning Region shown as Special Flood Hazard Areas (Zone A, AE or X) on the Flood Insurance Rate Maps for Warren County dated March 16, 1988, or any subsequent amendment or revision to said maps.

 

b.         In addition, along all other streams and water courses not shown as floodable by the Flood Hazard Boundary Maps or Flood Insurance Rate Maps, all land within 30 feet of the top of the bank is considered to be subject to flooding.

 

 

3.         Regulations for Subdivisions Containing Land Subject to Flooding

 

a.         All subdivision proposals shall be consistent with the need to minimize flood damage.

 

b.         All creeks, lakes, ponds, sinkholes or other drainage areas shall be shown on the preliminary and final subdivision plat.

 

c.         Every lot platted shall have a flood-free building site.

 

d.         All subdivision proposals shall have public utilities and facilities, such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage.

 

e.         All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hazards.

 

f.          Base flood elevation data shall be provided for all subdivision proposals containing land subject to flooding.

 

g.         Utilities

 

(1)       All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.

 

(2)       New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration.

 

(3)       If on-site waste disposal septic systems are to be used, a flood-free site shall be provided on each lot in order to avoid impairment to them or contamination from them during flooding.

 

h.         Fill

 

(1)       Land subject to flooding may be platted for residential use only if filled to such a height as will secure a flood-free site based on data submitted by the subdivider and prepared by registered professional engineers, provided such use of fill does not endanger health, life, or property or restrict the flow of water or increase flood heights.  Lots on fill will not usually be approved for septic tank drain fields.  In order to be considered for           development such lots must be served by a public sewer system.

 

(2)       No fill shall be placed in the floodway of the stream and if undetermined no closer than 30 feet from the top of the bank of any stream or water course unless the subdivider demonstrates that a lesser distance (but not less than 15 feet) is adequate based on watershed area, the probable runoff, and other topographic and hydraulic data prepared by engineers.

 

(3)       All bridges, culverts, and other drainage openings shall be designed so as not to restrict the flow of water and unduly increase flood heights upstream.

 

C.        Monuments

 

1.         Concrete monuments or other markers approved by the Planning Commission four (4) inches in diameter square, three (3) feet long, with a flat top, shall be set at points where the street lines intersect the exterior boundaries of the subdivision. The top of the monument shall have a metal plate with an indented cross to identify properly the location and shall be set flush with the finished grade.

 

2.         All other lot corners shall be marked with iron pins or pipe not less than three-fourth (3/4) inches in diameter and 24 inches long and driven so as to be flush with the finished grade.

 

D.        Streets - Design Standards

 

The following standards shall apply for the design of all streets in subdivisions located in the McMinnville Planning Region.

 

1.         General Standards of Design

 

a.         Arrangement

 

The arrangement of streets in the subdivision shall provide for the continuation of principal streets of adjoining subdivision, and for proper projection of principal streets into adjoining properties which are not yet subdivided, in order to make possible necessary fire protection, movement of traffic and the construction or extension, presently or when later required, of needed utilities and public services such as sewers, water and drainage facilities. Local streets shall be so laid out that their use by through traffic will be discouraged. Where, in the opinion of the Planning Commission, topographic or other conditions make such continuance undesirable or impracticable, the above conditions may be modified. The curvi-linear street layout will be encouraged by the Planning Commission.


b.         Conformity to the Major Road Plan

 

The location and width of all streets and roads shall conform to the official Major Road Plan.  The latest Major Road Plan Map is on file in the Office of the Warren County Register of Deeds and a copy of said plan is included in the front of this document

 

Where a street designated by the Major Road Plan as a "Proposed Road" crosses the proposed site of subdivision, right-of-way sufficient to meet the design standards for the functional classification of said street shall be dedicated to the public and shown on said plat.

 

c.         Relation to Adjoining Street System

 

The proposed street system shall extend any adjoining existing streets at the same or greater width, but in no case less than the required minimum width.

 

d.         Relation to Topography

 

The street plan of a proposed subdivision shall bear a logical relationship to the topography of the property, and all streets shall be arranged so as to obtain as many of the building sites as possible at or above the grade of the streets. Grades of streets shall conform as closely as practicable to the original topography.

 

e.         Flood Prevention

 

Streets which will be subject to inundation or flooding shall not be approved. All streets must be located at elevations which will make them flood-free in order that portions of the subdivision will not be isolated by floods. Where flood conditions are anticipated, profiles and elevations of streets will be required in order to determine the advisability of permitting the proposed street layout.

 

2.         Minimum Street Right-of-Way Widths

 

The minimum width of the street right-of-way, measured from lot line to lot line, shall be as shown on the Major Road Plan, or if not shown on such plan, shall be not less than as listed below.

 

a.         Local Streets................................................ 50 feet

 

b.         Local Streets with curbs & gutters............. 40 feet                       

 

c.         Cul-de-sacs (diameter)............................... 120 feet

 

d.         Collector Streets.......................................... 60 feet

 

e.         Arterial Streets and Highways.................... 80-150 feet

 

3.         Minimum Street Surfacing Widths

 

The minimum street surfacing widths shall be as follows:

 

a.         Local Streets................................................ 24 feet

 

b.         Local Streets with curbs & gutters............. 20 feet

 

c.         Cul-de-sacs (diameter)............................... 100 feet

 

d.         Collector Streets

              Minor........................................................... 28 feet

              Major........................................................... 32 feet

 

e.         Arterial Streets and Highways.................... 48 feet

 

Due to the diversity of the development in the planning region, ranging from sparsely populated agricultural areas to densely populated urban areas; required surfacing widths may necessarily vary with the character of building development, the amount of traffic encountered, and the need to provide space for on-street parking.

 

In general, streets through proposed business areas shall be considered either collector streets or arterial streets and the street widths of streets so located shall be increased six (6) feet on each side if needed to provide parking without interference to normal passing traffic.

 

4.         Additional Right-of-Way on Existing Streets

 

Plats for subdivisions that abut existing streets shall show the dedication of additional right-of-way to meet the minimum right-of-way width requirements.

 

a.         The entire right-of-way shall be provided where any part of the subdivision is on both sides of the existing street.

 

b.         When the subdivision is located on only one side of an existing street, one-half (1/2) of the required right-of-way, measured from the center line of the existing roadway, shall be provided.

 

5.         Substandard Existing Streets

           

The subdivision of property abutting existing streets that do not meet the minimum construction standards of these regulations shall generally be prohibited.  Should improvements to the existing street be required in order to meet the demands of the proposed subdivision, the cost of said improvements shall be borne by the developer unless determined otherwise by the City of McMinnville.

 

 

 

6.         Street Grades

 

a.         Grades on major streets shall not exceed seven (7) percent; grades on other streets shall not exceed 12 percent. No more than three (3) percent grade within 100 feet of any intersection with a collector or arterial street will be allowed and no more than 50 feet of any intersection with a minor residential or rural street.

 

b.         Upon preliminary plat approval, if the street grade appears questionable, a street grade profile map may be required for the questionable area before approval of final plat.

 

c.         Every change in grade shall be connected by a vertical curve constructed so as to afford a minimum sight distance of 200 feet, said sight distance being measured from the driver's eyes, which are assumed to be four and one-half (4 1/2) feet above the pavement surface.

 

d.         Profiles of all streets showing natural and finished grades drawn to a scale of not less than one (1) inch equals 100 feet horizontal, and one (1) inch equals 20 feet vertical, may be required by the Planning Commission.

 

7.         Curves

 

a.         Horizontal Curves

 

Where a deflection angle of more than ten (10) degrees in the alignment of a street occurs, a curve of reasonably long radius shall be introduced. On streets 60 feet or more in width, the center line radius of curvature shall be not less than 300 feet; on other streets it shall be not less than 100 feet.

 

b.         Tangents

 

A tangent of at least 100 feet in length shall be introduced between reverse curves on all streets.

 

c.         Curve radii at street intersections shall not be less than 20 feet (See Illustration 3 in Appendix A) and where the angle of street intersection is less than 75 degrees the Planning Commission may require a greater curb radius.  To permit the construction of a curb having a desirable radius without curtailing the sidewalk at a street corner to less than normal width, the property line at such street corner shall be rounded or otherwise set back sufficiently to permit such construction.

 

 

 

 

8.         Intersections

 

a.         Street intersections shall be as nearly at right angles as is possible and no intersection shall be at the angle of less than 60 degrees.  (See Illustration 4 in Appendix A).

 

No street intersection shall have more than four streets entering it, and the "T" or three-way intersection shall be used whenever possible.  Additional street right-of-way on local streets may be required at intersections with collector or arterial streets to permit proper intersection design for traffic flow.

 

Local streets intersecting with collector roads shall, in general, be at least 500 feet apart and at least 1000 feet apart when opening into an arterial street.  Local streets intersecting with other local streets shall, in general, be at least 200 feet apart.

 

b.         Street Jogs

 

Street jogs with centerline off-sets of less than 150 feet shall not be allowed if the proposed street is to connect with or is an arterial or collector street. Street jogs on local streets with centerline off-sets of less than 125 feet shall not be allowed.  (See Illustration 5 in Appendix A).

 

c.         Visibility of Intersections; Steep Grades and Curves

 

A combination of steep grades and curves shall be avoided. In order to provide visibility for traffic safety, that portion of any corner lot (whether at an intersection entirely within the subdivision or of a new street with an existing street) shall be leveled and cleared of brush (except isolated trees) and obstructions above the level three feet higher than the centerline of the street. If directed, the ground shall be excavated to achieve visibility.

 

9.   Dead-End Streets (Cul-de-sacs)

 

a.         Permanent

 

Minor terminal streets or courts designed to have one (1) end permanently closed shall be no more than 1200 feet long unless necessitated by topography. They shall be provided at the closed end with a circular turnaround having an outside pavement diameter of at least 100 feet and a street right-of-way diameter of at least 120 feet.  The circular turnaround may be centered on the main body of the street or off-set to either side.  When approved by the Planning Commission, alternate designs, including a "T" or "hammer head" configuration, may be used in lieu of the circular cul-de-sac.    (See Illustration 6 in Appendix A).      

 

b.         Temporary

 

Where, in the opinion of the Planning Commission, it is desirable to provide for street access to adjoining property, proposed streets shall be extended by dedication to the boundary of such property. Such dead-end streets shall be provided with a temporary paved turnaround having a roadway surface diameter of at least 100 feet.

 

10.       Private Streets or Permanent Vehicular Easements

 

a.         The Planning Commission discourages the platting of private streets or permanent vehicular easements as every subdivided property should be served from a publicly dedicated street.

 

b.         Private streets and permanent vehicular easements shall be developed to meet all standards required for municipal streets as provided in these regulations.  These include, but are not limited to, all requirements for street right-of-way widths, minimum surfacing widths, street grades, curves, intersections, street names, and street construction procedures and specifications.

 

11.       Reserve Strips

 

There shall be no reserve strips controlling access to streets, except where the control of such strips is definitely placed with the municipality under conditions approved by the Planning Commission.

 

12.       Special Treatment Along Major Arterial Streets

 

When a subdivision abuts or contains an existing or proposed major arterial street, the commission may require either marginal access streets, reverse frontage with screen planting contained in a non-access reservation along the rear property line, lots with rear service alleys, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.

 

13.       Sidewalks (Optional)

 

For the safety of pedestrians and of children going to school, installations of sidewalks on one side or both sides of the street may be required on certain collector and arterial streets, in the vicinity of schools, and in other locations where the Planning Commission considers sidewalks to be needed.

 

Sidewalks shall be located in the street right-of-way not less than one foot from the property line to prevent interference or encroachment by fencing, walls, hedges, or other planting or structures placed on the property line at a later date.

 

 

In a single family residential area concrete sidewalks shall be five (5) feet wide and four (4) inches thick. In multi-family or group housing developments sidewalks shall be five (5) feet wide and four (4) inches thick. In commercial areas sidewalks shall be ten (10) feet wide and four (4) inches thick.

b.         Free Flow of Vehicular Traffic Abutting Commercial Developments

 

In front of areas designed for commercial use, the street's width shall be increased by such amount on each side as may be deemed necessary by the Planning Commission to assure the free flow of through traffic without interference by parked or parking vehicles, and to provide adequate and safe parking space for such commercial or business district.

 

15.       Street Names

 

a.         Proposed streets, which are obviously in alignment with others already existing and named, shall bear the name of existing streets.

 

b.         New street names shall be substantially different so as not to be confused in sound or spelling with present street names as shown on the McMinnville or Warren County Official Street/Road Name Maps. The only exception to this policy is where a proposed street is an extension of (or is in alignment with) an existing street. Generally, no street should change direction by more than 90 degrees without a change in street name.

 

c.         The developer is required to erect street name signs in subdivisions within The City of McMinnville and its planning region. These add value to land subdivision and enable strangers, delivery concerns, emergency vehicles, and even potential buyers to find their way around. The subdivider should consult with the McMinnville Public Works Director or Warren County Road Supervisor for installation standards.

 

 

 

16.       Warning and Regulatory Signs

Such drainage facilities shall be located in the street right-of-way where feasible, or in perpetual unobstructed easements of appropriate width.

 

3.         Other Watercourses

 

Where a watercourse separates a proposed street from abutting property, provision shall be made for access to all lots by means of culverts or other structures of design approved by the Public Works Director or County Road Superintendent. Where a subdivision is traversed by a watercourse, drainage way, channel or stream, there shall be provided a storm water easement or drainage right-of-way as required, and it shall in no case be less than 20 feet in width.

 

4.         Storm Drainage Under Streets

 

Cross drains shall be provided to accommodate all natural water flow, and shall be of sufficient length to permit full width roadway and the required slopes. All cross drains that are to be laid under the roadway shall be of concrete construction.  The size openings to be provided shall be determined by the Rational Formula, but in no case shall the pipe be less than 18 inches in diameter. Cross drains shall be built on straight line and grade, and shall be laid on a firm base but not on rock. Pipes shall be laid with the spigot end pointing in the direction of the flow and with the ends fitted and matched to provide tight joints and a smooth uniform invert.

A culvert or other drainage facility shall, in each case, be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the subdivision.

 

7.         Responsibility for Downstream Drainage

 

The subdivider's engineer shall also study the effect of each subdivision on the existing downstream drainage facilities outside the area of the subdivision. Where it is anticipated that the additional run-off incident to the development of the subdivision will overload an existing downstream drainage, provision shall be made for the improvement of said condition.

 

8.         Storm Water Retention

           

The Planning Commission may require storm water retention facilities for subdivisions where the presence of Sinkhole Retention Areas, Flood Hazard Areas or water courses of limited capacity are the recipients of storm water discharge from the site of said subdivision.  In general, this requirement will apply only to those subdivisions planned to contain five (5) or more dwelling units or commercial and/or other structures which will consists of a total of 10,000 or more square feet of impermeable surface (roof and parking area).

 

When it is determined by the Planning Commission that storm water retention facilities are required, no plat for such subdivision shall be approved from which storm water run-off is discharged into public rights-of-way, public drainage structures or natural water-courses at a rate greater than the rate which water is being discharged from the site prior to the proposed development taking place.

 

The drainage plan accompanying the plat for all subdivisions meeting this criteria shall show all proposed discharge structures and points of storm water discharge from the site.  Said plans shall be accompanied by a set of calculations which illustrate the flow of storm water from each existing and proposed discharge point expressed as cubic feet per second (cfs) and gallons per minute (gpm).  Said calculations shall show this discharge of water under existing and proposed conditions.

 

9.         Land Subject of Flooding-See Section B of this Article for Special Requirements for Floodable Areas.

 

10.       Erosion Reduction

 

The developer shall utilize grading techniques, subdivision design, landscaping, sedimentation basins, special vegetation cover, and other measures to reduce erosion and sedimentation during and after development.

 

L.         Preservation of Natural Features

 

The developer shall, wherever possible, attempt to preserve all natural features which add value to residential developments and to the community, such as large trees or groves, water courses and falls, historic spots, vistas and similar irreplaceable assets.

 


ARTICLE IV        SPECIAL DEVELOPMENTS

 

A.        Planned Unit Development Subdivision Standards

 

The purpose of the Planned Unit Development (PUD) is to allow flexibility and innovation in land development and land use.  This form of development, which is also referred to as "cluster development" or "open space development," usually involves the clustering of dwelling units on certain portions of the site and generally includes common open space property owned and maintained by a property owners association.  It is an environmentally sound concept, because it can allow for development in the most suitable areas while preventing development in unsuitable areas such as flood plains or areas with steep slopes.  Also it is an economically sound concept; because it can reduce the costs for infrastructure (the length of street and utility lines can be significantly decreased).  

 

The McMinnville Zoning Code provides for two (2) types of Planned Unit Developments Districts: (1) PRD-Planned Residential District and (2) PCD-Planned Commercial District.  These zoning districts allow for the mixture of land uses such as traditional single-family houses, town houses, apartments, and some commercial and pubic uses.  Generally, the intent of the Planned Unit Development is to permit varied lot sizes and clustered development while at the same time preserving open space without increasing overall density and without increasing the effective impact on the community.

 

All Planned Unit Developments or similar such developments shall meet the following standards:

 

1.         The developer shall meet with the City Administrator, Codes Enforcement Official, and Staff Planner to become familiar with all applicable requirements.

 

2.         Shall be in compliance with all provisions of Section 11-511 of the McMinnville Zoning Code.

 

3.         In general, shall meet all requirements and minimum standards of design required in these regulations.

 

4.         Depending on the design of the development and/or types of residential units within, some or all of the development may be required to conform to TCA 66-27-101 through 123, entitled Horizontal Property Act.

 

B.        Large Scale Development

 

The requirements of these regulations may be modified in the case of large scale community or neighborhood units, such as a housing project, trailer court or shopping center which is not subdivided into customary lots, blocks, and streets, if the development is approved by the Planning Commission and if it is in conformity with the purpose and intent of these regulations.

 

 

C.        Condominium Developments

 

Proposed residential or commercial projects which will offer individual attached units for sale with or without any land, and with certain elements in common to all units may be required to conform with requirements of TCA 66-27-101 to 123, entitled the Horizontal Property Act.
