8. Design Criteria for the Conservation/Agricultural District. The following design criteria is to be used in conjunction with the Millheim Borough Zoning Ordinance, Conservation/Agricultural District regulations. This criteria follows the intent of that ordinance, which is to preserve the most suitable land for agricultural activities, preserve natural resources and features, and create neighborhoods that are an extension of, and follow as much as possible, the existing village development pattern in the Borough of Millheim.
(1) Primary conservation features, such as steep slopes (25 percent or greater), 100-year floodplain areas, and wetlands, shall be identified and avoided.
(2) Secondary conservation features such as slopes of 15 to 25 percent, prime agricultural soils (class I and II soils), mature woodlands, tree and hedgerows, and historic sites and structures shall be identified and avoided if possible.
The primary and secondary conservation features shall be identified as the conservation area. The conservation area shall be retained by the initial parent tract owner or an approved homeowners association. The allowable uses within the conservation area are as follows:
(a) Agriculture (see permitted in zoning district regulations).
(b) An estate lot for one single-family dwelling with allowance for an accessory dwelling if suitable for an on-lot septic system or public sewer is available.
(c) Park, recreation, and natural/ wildlife resource areas.
(d) Stormwater management areas.
(3) Once the primary and secondary conservation features are identified, the remaining area of the site can be considered as the potential development area (50% maximum of the total site area).
(4) Public sewer and water shall be provided to proposed developments within the identified potential development area. Lots shall not be less than 10,000 square feet nor exceed one (1) acre in total lot size.
(1) Woodlands, orchards, hedgerows, and large healthy trees should be preserved to create buffer areas to minimize conflicts between agriculture and residences.
(2) Development on fields should be located near existing neighborhoods, woodlands, or hedgerows and where feasible, on the least prime agricultural soils.
(3) Lots shall access interior and/or local roads that are extended from the existing neighborhoods within the Borough. The current rectilinear street pattern shall be continued in new development areas. Streets shall be designed in accordance with Millheim's regulations and shall have a maximum length of 600 feet between intersecting streets. Cul-de-sacs shall be minimized and where unavoidable shall provide a pedestrian connection to the next street system and/or to the identified conservation area.
(4) Pedestrian access and circulation in the form of sidewalks, paved paths, and trails from existing neighborhoods to the potential development area shall be provided.
(5) Historic, archeological/cultural, and natural sites identified by the Borough's Historic District along with County and State resources, shall be incorporated into the site design.
(6) A minimum riparian buffer area of 50 feet from identified streams and intermittent streams measured perpendicular from the stream bank edge shall be provided.
9. Parking and Parking Lots.
A. Parking shall be located on street to the maximum extent possible to provide the streetscape appearance that is traditional in the Borough and to serve as insulator between moving vehicles and pedestrians walking along the adjoining sidewalks.
B. Parking lots shall be located to the rear or sides of buildings with the exception of the Village-Mixed Use and Industrial Districts where parking shall be permitted in the front of buildings. [Ord. 242]
C. Parking lots and/or garages shall not be the dominant aspect of the building design and/or the streetscape as viewed from the street.
D. Live-work units shall have the parking ratio as required for a dwelling, as provided for in this Section.
E. Parking ratios for all other uses shall also be in accordance with this Section except that the parking ratio for multifamily dwellings shall comply with a Subsection of this Section. However, if the standards of this Section impose an excessive standard, as determined by Borough Council, the applicant shall demonstrate through the use of the empirical data from other built projects that a lesser standard can adequately serve the proposed use(s). In any event, the Borough shall hold in escrow the monetary value of the parking spaces not built for a period of two years after commencement of the use, and the development plan shall show the layout of the required parking areas to be held in reserve and include calculations on the potential impervious surface area addition. If after two years, the use is adequately serviced by the parking provided, escrow funds may be released. If the provided parking is not adequate, then the escrow funds shall be used to construct the needed parking.
F. All nonresidential parking areas shall be visually screened from existing and proposed streets by hedges, buffer plantings, decorative fencing, or similar elements.
10. Off-Street Loading Areas, Outdoor Storage and Trash Disposal Areas.
A. All loading areas and loading docks shall be located to the sides and rear of buildings. Loading docks shall not be visible from public streets. All loading areas and loading docks shall be set back at least 25 feet from the residential areas or the minimum buffer yard width as determined by Borough Council.
B. Outdoor storage or display of materials shall not be permitted.
C. Trash disposal areas shall be located within buildings or within an opaque screened area that completely hides the trash and is located to the side or rear of the building. All outdoor trash disposal areas shall be set back at least 25 feet from residential property lines.
