JURISDICTION The provisions of these regulations shall apply to all lands within Washington County, Maryland except land within municipal corporations. 105. APPLICATION No land within Washington County, outside incor- porated jurisdictions shall be subdivided, nor shall any lot be sold or building erected in a subdivision as herein defined, until a plat of the subdivision is approved by the Commission and the plat properly filed and recorded by the Clerk of the Circuit Court for Washington County, Maryland. In their interpretation and application, the provisions of these regulations shall be held to be minimum requirements, adopted for the promotion of the public health, safety, and general welfare. Whenever, the provisions of these regulations are at variance with the requirements of any other lawfully adopted rules, regulations, ordinances, deed restrictions or covenants, that provision which is more restrictive or imposes higher standards or requirements shall govern. 106. SUBDIVISION OF RECORD Any plat or subdivision recorded among the Land Records of Washington County prior to the effective date of this Ordinance shall be accepted as valid and no further approval by the Commission shall be required for the conveyance of lots so shown. 107.

Street Classifications A. Freeway or expressway system provides for the expeditious movement of large volumes of through traffic between areas and/or across, around or through urban and county areas. A freeway or expressway is a divided highway with full control of access A freeway abutting land. will have complete separation of conflicting traffic 11 flows while an expressway may have a few or n❑ grade separations and may be a stage development toward a freeway. In urban areas both will normally be a portion of a system or network of freeways. 8. Major arterial system provides for traffic movement between areas, and across portions of the urban areas, providing direct ser- vice to principal generators connecting to the freeway -expressway system and secon- darily for direct access to abutting land. Major arterial streets are therefore sub- ject t❑ necessary regulations and control of parking, turning movements, entrances, exits and curb use. Major arterial streets are often divided highways and may have some control of access. The individual major arterial streets combine to make a system for city -county wide traffic movement. Geometric designs may vary widely in the city and county but the function remains the same. C. Collector street system provides direct service to residential areas from major arterial streets and highways for traffic movement within neighborhoods and for direct access to abutting property. Collects local traffic from the neighbor- hoods and delivers it to the nearest major arterial highway. D. Local street system provides for direct access to residential, commercial, indus- trial or other abutting land for the local traffic movements and connects to collector and/or major streets. E. Marginal access or service streets - Minor streets parallel with and adjacent to major arterial streets which provide access to abutting properties and protection from rapid through traffic. F. Cul-de-Sacs - Short streets having one end open to traffic, the other end being per- manently terminated by a vehicle turn around. 12 47. Subdivision ❑f Land and Subdivide Subdivision means the division of a lot, tract, or parcel of land into two or more lots, plats, sites, or other divisions of land for the pur- pose, whether immediate or future, of sale or of development. It includes resubdivision and, when appropriate to the context, relates to the process of resubdividing or to the land or territory subdivided, as defined in Article 668, of the Annotated Code of Maryland (1957) as amended. Commentary "This definition is not intended to include a division of land among the immediate members of a family for personal use and not for develop- ment; a division of land upon dissolution of a bona fide partnership in existence for two or more years; or a division of land exclusively for agricultural purposes and not for develop- ment." 13 ARTICLE III PROCEDURE FOR SUBMISSION OF SUBDIVISION APPLICATIONS 301.

STREET LAYOUT AND DESIGN 1. General A. The proposed plat shall provide for continuation of any existing roads or streets (constructed or recorded) in accordance with adopted highway plans. S. A tract proposed for subdivision into parcels larger than normal building plots and intended for future subdivision rather than immediate development shall be divided so as to allow for future opening of streets and such further logi- cal subdivision as can be foreseen. C. All streets shall, as far as practicable, be in alignment with existing adjacent streets by continuation of the center lines thereof or by adjustments by curves, and shall be in general conformity with the Plan as is now or hereafter shall be adopted in whole ❑r in part for the most advantageous development of the area in which the subdivision lies. D. Residential streets shall be designed to discourage rapid through traffic. E. Where it is desirable in the opinion of the Commission to provide street access to adjoining property, proposed streets shall be extended by dedication to the boundary of such property. F. Proposed streets and highways shall be adjusted to the contour of the land as far as practicable so as to produce useable lots and streets. G. A subdivision plat involving new or existing streets crossing railroad tracks shall provide adequate right of way, in- cluding approach right of way and slope easements, for construction of underpass ❑r overpass in accordance with Article UI, 602. H. A residential street paralleling a railroad shall be at a distance from the track sufficient to provide lots with a minimum of one hundred sixty (160) feet depth backing t❑ the railroad right of way, or at a distance suitable for the appropriate use of the intervening land as for park purposes in residential districts, or for commercial or industrial uses in 29 appropriate districts. Such distance shall als❑ be determined with due regard for the requirements ❑f approach grades and future grade separations. I. Railroad tracks shall not be included within the rights of way of roads or streets, except for crossings or rail transit lines outside paved traveled portion of the road. J. Subdivisions platted along both sides of an existing street shall provide the entire minimum right of way in accordance with Article IV. 403. K. Subdivisions platted along only one side of an existing street shall provide one-half (I) ❑f the minimum right of way measured from the centerline of such existing street. L. Half streets are prohibited, unless determined by the Commission to be essential to the reasonable development of the subdivision in conformity with the other requirements of this Ordinance ❑r unless the Commission finds it to be practicable t❑ require the dedication of the other half when the adjoining property is subdivided. Whenever a half street exists adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract. 2. Intersections A. Streets shall intersect one another as nearly as possible at right angles and in no case shall the angle of intersection be less than seventy (70O) degrees, unless otherwise determined by the County Engineer. O. The location of intersections with major arterial highways shall be determined by the Commission in a manner that will avoid the movement of through traffic crossing such major arterial highways. Proposed inter— sections with major arterial highways shall be spaced no closer together then seven hundred and fifty (750) feet. C. Property lines at street intersections shall be rounded with a radius of at least twenty— five (25) feet. Alley intersections shall be rounded with a radius of at least ten (10) feet. When the smallest angle of the inter— section is less than seventy (70O) degrees, 30 this minimum radius shall be increased. In commercial districts a comparable chord may be used in place of an arc. D. Minimum curb radius at street intersections shall be not less than twenty-five (25) feet. E. Intersections involving the junction of more that two (2) streets should be avoided. F. The number of intersections ❑f minor streets with major streets should be kept to a minimum. G.

Street Grades A. Street grades, except under extreme physical conditions, shall not exceed the following: Tvoe of Street Percent Grade Major Arterial 5 Secondary 7 Residential Collector 8 Local 8 Cul-de-sac 8 B. For adequate drainage the minimum street grade shall be not less than one-half of one (0.5) percent. 4. Street Alignment A. Between reverse curves with a deflection angle on the center line greater than five (5°) degrees following minimum tangents shall be introduced. Type of Road Tangent in Feet Major Arterial and secondary 200 Residential Collector 100 B.

Minimum Radius Type of Road of Curvature in Feet Major Arterial 500 Secondary 300 Residential Collector 200 Local 100 C. All changes in street grade shall be connected by vertical curves designed to provide the following minimum sight distance as measured between points three and three quarters (3.75) feet above the center line of the road or street surface, and a point one-half (0.5) feet above the center line of road and street surface. Minimum Sight Type of Road Distance in Feet Major Arterial 600 Secondary 500 Residential Collector 300 Local 200 5. Dead -End Streets Prohibited except as stubs to permit future extensions to adjoining tracts or where necessitated by topography, or where, in the opinion of the Commission they are for the type of development contemplated and are designed as cul-de-sacs. 6. Cul-De-Sacs Permanently designed Cul-de-secs shall not be longer than ❑ne thousand tw❑ hundred (1,200) feet from the nearest intersecting street, and shall be provided at the closed end with a turna- round having a radius of at least fifty (50) feet.

Fifty-year flood plain is defined as that area which would be inundated by storm water run off equivalent to that which would occur with a rainfall of fifty-year frequency after total development of the watershed. 2. Unsafe land. The Commission shall also restrict such subdivision of any land which is found by the Commission t❑ be unsafe for development use by reason of its being subject to flooding, erosive stream action, unstablized slope or fill or otherwise located in a situation so that safe, healthful development cannot be maintained on the land. 3. Building restriction line. A building restriction line is a line designating an area in which development or building is restricted to agricul- tural or recreational purposes, except as other- wise provided herein. A building restriction line shall be used to designate flood plain or unsafe building areas in all cases where the area is not shown on the plat as right of way or easement in accordance with this Article. 4. Part of lot. The Commission may permit, as to flood plain or unsafe land, that it be platted as a part ❑f a lot in which there is sufficient safe ground to erect a building or dwelling within the required setbacks. In the event that such land is platted as a part of a buildable lot, there shall be placed on such platted lot a building restriction line which shall be located so as to provide at least a twenty-five (25) foot setback between any building and the unsafe areas and a greater setback where necessary to provide positive drainage between the building and unsafe area. 5. Removal. When any unsafe or flood plain land has by subsequent change in conditions become safe for building by finding ❑f the Commission, the building restriction line may be removed by the recording of a new plat approved by the Commission. 6. Denial of permission. No permission shall be granted within any building restriction line or in other areas within a flood plain or on unsafe land for any structure or additions t❑ existing structures except for fences, agri- cultural structures, public utility and other such structures approved by the Commission or county as necessary for the safety and general welfare ❑f the citizens ❑f the county. 7. Drainage and flooding. Drainage and flood control facilities shall be provided in conformation with the County Drainage and Flood Control Plan, to the extent necessary to serve the subdivision. Developer shall provide adequate drainage control facilities in such subdivision, and provide for the flow of surface water reasonably anticipated when development is completed. 37 407. NON-RESIDENTIAL SUBDIVISIONS 1. General Non-residential subdivisions shall include industrial tracts, and may include neighbor- hood and community commercial tracts. 2. Standards In addition to the standards in this Ordinance which are appropriate to the planning of all subdivisions, the subdivider shall demonstrate to the satisfaction of the Commission that the street, parcel and block pattern proposed is specifically adapted to the layout antici- pated and takes into account other platting in the vicinity. The following standards shall be ❑bserved: A. Proposed industrial parcels shall be suitable in area and dimensions to the types ❑f industrial platting anticipated. U. Street rights of way and pavement shall be adequate to accommodate the type and volume of traffic anticipated to be generated thereon. C. Minimum requirements may be specified by the County Engineer with respect to street, curb, gutter and sidewalk design and construction for the purpose of pro- tecting the public health, safety and general welfare of the community. D. Minimum requirements may be specified by the Commission with respect to the installation of public utilities, in- cluding water, sewer and storm drainage for the purpose of protecting the public health, safety and general welfare of the community. E. Streets carrying non-residential traffic, especially truck traffic, shall not normally be extended t❑ the boundaries of adjacent existing ❑r potential resi- dential subdivisions or connected to streets intended for predominantly residential traffic. 408. PARKING 1. In residential subdivisions, consideration shall be given to providing off-street parking adequate for the particular type of subdivision. A private garage, parking space or private I;] driveway, shall be provided for single- family dwellings. Parking bays not physi- cally divided from the roadway may be used on strictly local streets with little traffic. This requires a minimum of two hundred (200) square feet per car. Parking bays shall be divided from the roadway on streets carrying more then local traffic. This requires a minimum of three hundred sixty (360) square feet per car including aisles and divider. 2. Where lots are platted for commercial, industrial, or non-residential uses, adequate provision shall be made for off- street parking, loading, and unloading on each individual lot or in an area designed to serve a group of such lots. 3. Where lots are platted for semi-public use, e.g., churches, adequate provision shall be made for off-street parking. 39 ARTICLE V NEW SUBDIVISION TECHNIQUES The procedure for obtaining approval for the following new patterns of land subdivision -- Cluster Development, Town House Development, Planned Residential Unit or Open Space Community and Mobile Home Park shall be as outlined hereunder: 501.

Open space areas preserved by the develop- ment shall comply with the general pur- poses of Open Space Community development and a plan setting forth the post -develop- ment utilization of those areas must be evolved by the developer. E. Land dedicated to public use for school and park sites may be counted in the average net lot area, provided that development of the remaining land can be accomplished in compliance with the purposes of this Section. F. The minimum area for Open Space Community development shall be not less than ten (10) acres. It may be owned, leased or controlled by a single person, corporation, homes association or by groups of individ- uals or corporations. G. The minimum correlated standards for land area, floor area, open space, livability space, recreation space and car storage capacity for Open Space Community develop- ment are land use intensity standards published in Federal Housing Administration's Minimum Property Standards for Multi -family Housing (FHA 2600) dated November, 1963, as amended. H. The land -use intensity rating for a Planned Unit Development or Open Space Community project (excluding commercial area) shall range between Land -use Intensity Ratings of L1R 3.2 and L1R 6.2. A higher Land - use Intensity Rating may be granted by the Commission after a Public Hearing has been held on the planning feasibility of the development. The Commission shall) in determining the actual Land -use Intensity Rating applicable to a Planned Unit Develop- ment subdivision projects follow the proced- ure in FHA's Land Planning Bulletin No. 7, entitled "Land -use Intensity Rating" dated September, 1963, as amended.

MOBILE HOME PARK 1. Purpose To provide subdivision standards to regulate and control the design of mobile home parks. A. Mobile Home Parks may be platted on the cluster pattern to provide greater flexibility of layout. Maximum density shall be nine (9) mobile home lots per net acre with common open space, recrea- tional facilities and community sanitary facilities. B. The proposed mobile home park plat shall show the dimensions, locations and area of all rights of way, streets, walkways, parks, school sites and other open spaces. The proposed mobile home park plat shall be prepared by and have the seal of an engineer or land surveyor duly registered to practice in the State of Maryland. C. In recommending upon and approving mobile home parks, the Commission shall consider the location, size, and spacing of mobile home lots, access and circulation for ve- hicles and pedestrians, streets, parking areas, play areas and open spaces. If said mobile home park plat contains no dedication to the public for streets or utilities or should it be contemplated that the facilities of the county shall not be used for maintenance of streets, side- walks, water and sewer lines, garbage collection or other related functions, then such owner shall be required to record with such mobile home park plat a convenant that he will maintain said streets, sidewalks, water and sewer lines in compliance with the minimum standards as established by Washington County, and that should he fail to maintain said standards in any of these respects, the said county may, after ten (10) days' notice to such owner, effect all the neces- sary repairs or improvements as required to maintain said minimum standards and the cost of all these and necessary repairs or improvements shall become a lien against said real estate and enforced and recorded as mechanic's liens are enforced and recorded against such real estate, and said covenant shall contain the following proviso: "that , being the owner or owners of the real estate contained in the above attached mobile home park plat hereby consent that if they or their assignees, heirs or those holding or owning said land through said owners fail to maintain the streets, sidewalks, water and sewer lines according to and in compliance with the minimum standards for maintenance of streets, sidewalks, ri, water and sewer lines as established by the county that after ten (1D) days notice in writing the owner of said land as shown upon the tax records at the County Assessor's office of Washington County and at the address therein shown, then said owner assignees, heirs and those holding or owning through said owners hereby authorize the said County to make all necessary repairs and perform all necessary maintenance and further authorize said Washington County to file a mechanic's lien against said real estate and enforce said lien pur- suant to laws then applicable." 2. Conditions for use The use of the Mobile Home method ❑f develop- ment shall be subject to the following conditions and regulations: A. The area, tract of land or property to be subdivided shall contain at least three (3) acres of net development area excluding areas for parks, schools, streets, rights of way and other related uses. B. Maximum lot density permitted far the net development area shall be nine (9) mobile home lots per net acre. C. Each lot subdivided shall provide for one of the following: a. One -Family mobile home unit. b. One -Family compact or expandable mobile home unit. c. Uses accessory to any of the above or other uses similar to the above, which, in the judgement of the Commission are similar to and not more objectionable to the health, safety and general wel- fare of the subdivision. 47 D. No mobile home in a Mobile Home Park shall be occupied unless it is served by community water and sanitary facilities capable ❑f secondary treatment ❑r better. E. The minimum area of a Mobile Home lot shall be four thousand four hundred (4,400) square feet. F. The minumum average mobile home lot width shall be forty (40) feet. G. Every Mobile Home lot shall front onto a forty (40) feet street or right of way. 505. PROCEDURE FOR APPROVING NEW SUBDIVISION TECHNIQUES In order t❑ obtain approval for Cluster Develop- ment, Town House Development, Planned Residential Unit or ❑pen Space Community and Mobile Home Park the following procedure shall be followed: 1. Optional Consultation Pre -application plans shall be submitted in accordance with the format set forth in Section 302 of Article III of this Ordinance. In weighing the suitability of the land for Cluster Develop- ment, Town House Development, Planned Residential Unit or Open Space Community and Mobile Home Park the Commission shall consider, among ❑ther things, the nature of the site, and the use of adjacent and nearby land. 2. Preliminary Plat Application A Preliminary Plat shall be filed and processed in accordance with the procedure set forth in Sections 303 through 309 of Article III of this Ordinance. A. In addition to the information required above the plan shall also show the approxi- mate locations ❑f all proposed improvements, except single-family detached dwellings. The plan shall be accompanied by a prelim- inary statement or proposal including specific documents showing the ❑wnership, method of maintenance and utilization ❑f the common open space within the subdivision. Eu B. In considering the Preliminary Plat the Commission shall give particular consi- deration to the following: a. The influence, if any, that the pro- posed site development plan may be expected to have upon existing or future development in adjacent and nearby areas; b: The spatial relationship between the buildings and the common open space; and c. The location, character, area, and dimensions of the common open space and its usefulness for the common recreational or other purposes for which it is intended to be used. 3. Application for Final Plat After the Commission has approved a Preliminary Plat, application shall be made for the approval of a Final Plat. This Final Plat shall be subject to all of the requirements of Sections 310 through 313 of Article III of this Ordinance and in addition shall be accompanied by the following supporting exhibits: A. A site development plan showing the locations of all the buildings and parking areas and other inprovements and the pro- posed finished topography of the land. B. A detailed statement or proposal, including covenants, agreements, ❑r other specific documents, towing the ownership of and ,method of maintenance and utilization of those areas within the subdivision that are declared to be open space for common use. Development, construction ❑r other rights in the open space areas shall be reserved unto the ownership ❑f the land for the indicated recreational or scenic uses only. Covenants, agree- ments, etc., shall be in perpetuity and shall include easements to the public for utility rights of way. Portional Final Plats may be submitted as set forth in Section 312 of Article III of this Ordinance provided that a variance of not more than fifteen (15%) percent from the allowed density of development shall be permitted for any portion; and provided further that the density of development for the entire tract as approved on the preliminary plan shall not be exceeded. 4. Approval of Final Plat Procedure for final approval shall be in accordance with Section 313 of Article III of this Ordinance. In addition, the Commission shall examine the proposed development plan and supporting exhibits to determine whether they will result in the accomplishment of the purposes of the Cluster Development, Town House Development, Planned Residential Unit or Open Space Community and Mobile Home Park method of development and that they are substantially in compliance with the approved preliminary plan and its accompanying documents. If the Commission finds that the proposed Final Plat and supporting exhibits satis- factorily meet all of the requirements it shall approve the plat. The Commission shall notify the applicant in writing of its approval or dis- approval promptly but in no case later than thirty (30) days after receiving the application, unless the applicant consents t❑ the extension of this time limit. In case of disapproval the reasons therefor shall be stated. When approved by the Commission the Final Plat and its accompanying exhibits shall thereafter be the official plan for the development of the area involved. 5. Recording of Final Plats Procedure for recording a Final Plat for Cluster Development, Town House Development, Planned Residential Unit or Open Space Community and Mobile Home Park shall be in accordance with Section 314 of Article III of this Ordinance. Final Plats filed shall contain a statement indi- cating that the land lies within an approved Cluster Development, Town House Development, Planned Residential Unit or Open Space Community and Mobile Home Park development, that subdivision or re -subdivision is not permitted and that develop- ment of the land is permitted ❑nly in accordance 50 with the land uses indicated on the approved development plan. Covenants and/or joint -use and maintenance agreements affecting the common lands shall be recorded simultaneously with the plat. 51 CL E VI IND UTILITY IMPROVEMENTS Utilities and sewers should be installed under paved areas of streets only when absolutely necessary. 602. MINIMUM STANDARDS FOR NEW STREET AND HIGHWAY CONSTRUCTION. New streets, highways, alleys, sidewalks and Lcross walks with appurtenant drainage and other facilities in each new subdivision shall be constructed by the subdivider or developer in accordance with the specifications of the Washington County Specifications for Road and Street Improvements. The County shall participate in the cost of "oversize" improvements within the subdivision if it is con- sidered that such oversize improvements are necessary to serve large areas of land not in the subdivision and if the cost of such oversize improvements is an unreasonable burden on the subdivider. In the case of a plat containing lots fronting on an existing state, county or municipally maintained road, the subdivider shall provide required right of way as necessary to serve the needs of such subdivision for access and traffic as required by the Washington County Specifications for Road and Streethnprovements. Hi Where a midblock crosswalk or pedestrian path is included in a subdivision plan and is dedicated to public use, the subdivider shall grade and construct a paved walk therein, such construction to be according to a plan approved by the County Engineer. 603. PIPE STANDARDS AND SIZES. The Washington County Specifications for Road and Street Improvements shall be used in each new subdivision. 604. STORM DRAINAGE. 1. A storm water sewer system or a surface Li drainage system shall be provided for not less than a ten year storm criteria, to serve the area being subdivided. Such system shall be in accordance with the plans and specifications approved in the Prelimi- nary Plat. L I ILi 53 Li 2. Wherever curbs and gutters are provided ❑r when the County Engineer determines the natural surface drainage to be in- adequate, the subdivider shall construct a storm water sewer system with catch basins appropriately spaced along the streets in the subdivision. Valley gutters extending across the street surface shall not be used. 3. A natural surface drainage system shall be permitted when curbs and gutters are not provided and the natural drainage will, in the opinion of the County Engi- neer and approval of the Commission, adequately drain the storm water from the subdivision. The drainage ways should be shallow swales sowed in grass rather than deep, open ditches. Roadside drainage shall not be disrupted by pri- vate driveways. The subdivider shall install a suitable pipe of adequate size t❑ permit the free flow of water at those points where such driveways intersect the roadside drainage way. 4. In the design of a storm water sewer sys- tem for a subdivision, the present and future expected run-off from the larger drainage areas should be considered. For this reason, it may be desirable that larger sewers then those needed to ser- vice the immediate subdivision be in- stalled and certification by a registered professional engineer that all proposed drainage and structures are adequately designed to safely handle surface drain- age from a higher watershed area shall be provided for approval by the County Engineer. 5. The County shall participate in the cost ❑f "oversize" improvements within the sub- division if it is considered that such "oversize" improvements are necessary to serve large areas of land not in the sub- division and if the cost ❑f such "over- size" improvements is an unreasonable burden on the subdivider. 54 605. PUBLIC UTILITIES 1. General Pipelines, electric power and energy transmission and distribution lines and cables, and telephone and telegraph lines and cables shall be underground in a sub- division where the preliminary subdivision plan is filed subsequent to the Rules and Regulations of the Maryland Public Service Commission adopted November 1, 1968, and as hereafter amended, except that where determined by the Public Service Commission existing lines and transmission lines may be excluded. The Public Service Commission of Maryland may also grant exceptions from its underground rules. 606. MONUMENTS AND MARKERS 1. All monuments shall be installed in accordance with Maryland State Law and shall be of concrete or stone and not less than six (6) inches diameter or four (4) inches square and thirty-six (36) inches long. The center shall be marked on the top by either a copper dowel, set flush with the top, three - eights (3/8) inch in diameter and two and one-half (2 1/2) inches long or by crossed scores at least one-half (1/2) inch deep. Monuments shall be set so that the top is level with the adjoining established grade. 2. The corners of all lots shall be marked by galvanized or wrought iron pipe, or steel bars at least two (2) feet in length end not less than five -eights (5/8) inch in diameter, the top of the pipe or bar t❑ be set level with the established grade adjoining it. 55 607. CURBS AND GUTTERS 1. Curbs and gutters need not be installed along streets in the subdivision unless deemed necessary by the County Engineer for adequate drainage of storm water or for factors of safety. Curbs and gut- ters must be of integral concrete or other approved design and the materials and methods of construction shall con- form to the latest approved minimum requirements of the Washington County Specifications for Road and Street Improvements or any amendment thereto. 608. SIDEWALKS 1. Concrete sidewalks need not be installed along streets in the subdivision unless deemed necessary by the County Engineer for pedestrian safety or convenience. Sidewalks shall be at least four (4) feet wide and installed on either or both sides of each street and located within the street right of way one (1) foot from the street right of way line and shall conform to the Washington County Specifications for Road and Street Improvements and any amendment thereto. 609. STREET NAME SIGNS Standard street signs the intersection of all streets in the and method of display shall be subject County Engineer. 610. COMPLETION shall be installed at subdivision. The signs to approval by the Upon completion of the installation of streets, storm drainage, water supply, sanitary sewers and sewerage disposal systems, a copy of the final plans and speci- fications as built shall be filed with the County Engineer. 56 611. WATER AND WASTE WATER FACILITIES 1. General Before approving a subdivision, the Commission shall consider the availability of water and waste water facilities or the lack thereof to the proposed subdivision. Determination shall be made by the Washington County Sanitary Commission and the County Health Department, as applicable, for the proper type of water supply and sewage disposal to be required in each subdivision. All proposed subdivisions must comply with the Washington County Comprehensive Water and Waste Water Plan. Interim facilities will be required for all subdivisions built as high density subdivisions, unless supplied public facilities by adjacent municipalities or Washington County Sanitary District. A. Subdivision adjacent to and within a two mile radius of a municipality with public facilities shall petition the municipality for public facilities. A copy of the petition and the reply from the municipality shall be included with the Preliminary Plat. B. In the event that the municipality will not serve the proposed subdi- vision, the subdivider shall petition the Sanitary Commission for the es- tablishment of a Sanitary District. A copy ❑f the petition and the San- itary Commission's reply shall accom- pany the Preliminary Plat. C. In the event that neither the munici- pality nor the Sanitary Commission deem it economically feasible to supply the proposed subdivision with public facilities, an Engineer's re- port shall be prepared by the appli- cants Engineer to determine the feas- ibility of installing interim facil- ities in the proposed subdivision. 57 D. In the event that the Engineer's Report states that the public facil- ities are not feasible, and that in the ❑pinion of the Washington County Health Department the subdivision will not create a condition prejudicial to public health, only a low density development will be approved. 2. Central Water and Sanitary Systems A. All subdivisions shall be supplied with private or public central water and sewer facilities when conditions affecting the subject property result in one of the following determina- tions: 1. Public water and sewer connections are available to the proposed lots from existing mains, or 2. Existing public water and sewer mains shall be extended to serve the subdivision, or 3. It shall be mandatory for sub- divisions in excess of 25 lots or subdivisions located in areas which exceed the maximum number of bed- rooms permitted per gross acre (Table Page 77) that public sewer- age facilities be installed. Sub- divisions less than 25 lots or de- veloped in areas having less than the permitted bedroom facilities per gross acre and meeting all ❑ther criteria established by the State and County Health Department, private disposal facilities may be considered. B. The subdivider shall ascertain in writing the availability of public sewerage and water prior to submis- sion of a plat. Prior to recording of a Final Plat of a subdivision to be served by public water or sewer or both, the subdivider shall produce 58 evidence that he has complied with the conditions, if any, required for the installation of the utilities. In those cases where a private cen- tral system is to be used, the de- veloper shall secure the necessary approval ❑r permit for installation and operation of the system from the Washington County Sanitary Commission, and County Health Department, if applicable. C. For the location of any parts of a private system within the county or state road rights of way, necessary franchise or permits to use public roads shall be obtained from the county ❑r state as applicable. D. Individual Systems 1. Individual lot systems. In sub- divisions without public water or sewer ❑r approved central water or sewer systems, all lots shall be approved for individual wells or septic systems ❑r both by the County Health Department. No Final Plat containing such lots shall be approved by the Commission until written approval of such plat with respect to such lots has been re- ceived from the County Health Department. 2. If individual water supply and/or sewage disposal systems are to be provided, the Preliminary Plan shall show the proposed location of water supply wells, sewage disposal areas and percolation tests, including ex- isting wells and sewerage systems located within 100 feet of the sub- division boundaries. 3. Lots for individual septic systems. Lots to be sewered by individual septic systems, and to use private water systems, shall have a mini- mum area of twenty thousand (20,000) M square feet. The number of bed- room units per gross acre per- mitted shall be based on the fol- lowing table in order that there shall not be septic systems in close proximity to wells, to pro- vide sufficient area on lots for replacement facilities as required, and to avoid failure ❑f systems when a large number of septic sys- tem lots are developed in close proximity. If the total number ❑f subdivided lots using ❑r potentially using individual septic systems within the proposed subdivision and within one thousand (1,000) feet ❑f every boundary of such subdivision is: Maximum number ❑f bedrooms permitted per gross acre within the land proposed to be subdi- vided: With public With individual water water supply a. 0 - 25 lots 6.0 5.0 b. 26 - 50 lots 5.0 4.0 c. 51 or more lots 4.0 3.0 When the County Health Department finds it is necessary to preserve safety of water supply and insure functioning of septic system by reason of topography, soil type and conditions, surface and subsurface drainage conditions, water table level and history of failure ❑f sep- tic systems in the adjacent areas and extent of septic system development in adjacent areas, increased lot sizes may be required over and above the densities permitted above, or public facilities will be required. 612. PERCOLATION TESTS 1. Percolation tests shall be performed under the supervision of the County Health Department following the pro- cedures as outlined in the Manual of Septic Tank Practices, Public Health Service Publication published by the Department of Health, Education and Welfare. Minimum ownership of pro- perty shall be determined in accor- dance with the following table: LOT SIZE Using Using Public Time Required for a Individual Wells and Water Facilities and one (1) inch Sewerage Facilities Individual Sewerage Facilities Drop Min. Width Min. Area Min. Width Min. Area (Minutes) (Feet) (Sq. Feet) (Feet) (Sq. Feet) 2 to 5 100 20,000 10❑ 15,000 6 to 15 125 25,000 100 17,500 16 to 25 150 30,000 100 20,000 26 to 30 150 40,000 150 30,000 Over 30. Considered Impervious - Not Approvable 61 2. Each lot area shall depend on the per- colation test on that lot. Should the developer wish to use uniform lot areas, the area shall be based on the average ❑f the time for 80 per cent of perco- lation tests conducted in the area ex- cluding the low 10 per cent and high 10 per cent. No lot having a percolation rate exceeding 30 minutes shall be in- cluded on a plat. Where less than two minutes is required for a 1 inch drop, the approval ❑r re- jection of the area for subdivision purposes shall be at the discretion of the Approving Authority. 3. Design criteria for individual disposal facilities for each lot in the subdivision shall be based on percolation tests on undisturbed soil or on the ❑riginal soil after grading is performed. No perco- lation tests shall be performed in fill ground. 4. Minor variations in lot widths and areas given in the table not exceeding two (2%) per cent ❑f the table values may be al- lowed when special conditions warrant such variations. 613. INDIVIDUAL WELLS 1. In all subdivisions when individual wells for water supply and individual sewage disposal facilities are proposed, if in the judgement of the County Health Depart- ment, the disposal area will contaminate the waterbearing strata to be utilized for a potable water supply, all or part ❑f the subdivision shall be rejected. 2. Test wells shall be drilled to determine the quality and quantity of the proposed underground water supply for individual or community service. Water analysis and Driller's Logs are to be part of the application t❑ the Health Department. WA 614. SEWERAGE 1. If only public sewerage is available, the minimum lot area shall be ten thousand (10,000) square feet with a minimum width of seventy-five (75) feet. In this situa- tion the "Lot Area" may include the area having land slopes exceeding twenty-five (25%) per cent.
