Performance standards and criteria. The following criteria shall be satisfied to protect the public health, safety and welfare of the public at large. The applicant shall furnish in writing together with any application for use sufficient evidence that the proposed use will not produce any nuisance in excess of the measurable performance standards listed below.

(1)

No smoke or other air contaminant shall be discharged into the atmosphere for a period or periods aggregating more than three minutes in any one hour which is darker in shade than is designated at No. 2 on the Ringlemann Chart, as published by the United States Bureau of Mines, or which is of such capacity as to obscure an observer's view to a degree equal to or greater than does smoke designated at No. 2 on the Ringlemann Chart.

(2)

Offensive odors, as defined by Section 22a-174-23 of the regulations promulgated by the Connecticut Department of Energy and Environmental Protection, shall not discharge beyond the property line of an operation that stores, uses or produces a substance which will cause said odor. Any determination of a violation of Section 22a-174-23, as may be amended from time to time, constitutes a violation of this provision. Where lot lines bounding an industrial use adjoin a residential district, there shall be no offensive odors noticeable at said lot's property lines.

(3)

No noise or vibration which is objectionable due to volume, frequency or shrillness shall be transmitted outside the property where it originates.

(4)

No offensive or harmful wastes shall be discharged into any stream, watercourse, adjoining property, sanitary sewer, septic system, or storm drain.

(5)

No activity shall be conducted which is hazardous or dangerous to persons or property.

Building design standards. Architectural renderings of the building elevations (front/side/rear) shall be submitted to the Commission for its review and approval along with a floor plan. The facade of all buildings that are visible from any street or other public areas shall be of some architectural treatment approved by the Commission.

(1)

Exterior siding materials shall be of decorative masonry, wood, metal, stone or approved alternate material. Exterior design features, including materials, texture, color and trim detailing, shall be included on all building elevations to the extent which maintains overall design continuity.

(2)

Monotonous building forms are to be avoided by using various methods to help create interest and reduce scale. Examples include the staggering of vertical walls, recessing openings, providing upper-level roof overhangs, using deep score lines at construction joints, contrasting compatible building materials, and using horizontal bands of compatible colors. A variety in roof shapes and form is encouraged to add diversity of the buildings as well to enhance scale and complement the features of nearby buildings. Where parapet walls are used, they should be treated as an integral part of the building design.

(3)

The size of windows and doors should relate to the size of the wall in which they appear. Monotonous repetition should be avoided where possible in the location, size and shape of windows and small doors. Mirrors or highly reflective glass shall not cover more than 20% of a building surface visible from a street. Additionally, utility doors, fire doors, loading docks and other potentially unsightly service features should be designed to blend with the building's architecture.

(4)

Primary buildings in close proximity on the same property should have harmonious proportions and similar architectural styles. Nearby accessory buildings should be of compatible design and treatment.

(5)

Mixed-use buildings containing nonindustrial uses should highlight the public entry to the structure to create a sense of human scale and to emphasize a primary entry feature.

(6)

The mixing of unrelated architectural styles, materials and details is to be avoided.

(7)

All HVAC and other building utility systems shall be screened from view from the public street and abutting property.

Site preservation and landscaping. The application shall include a landscape plan and a site constraint plan prepared by a State of Connecticut-licensed landscape architect. The characteristics of the site are to be incorporated into the design to take advantage of topographic features, provide buffering of adjoining land uses, and retain the prominent natural landscape and environmental features of the property through:

(1)

Minimizing soil and tree removal.

(2)

Design grading to blend with the natural terrain and avoid creating steep slopes.

(3)

Treating disturbed surfaces to encourage plant growth and soil stabilization by providing the necessary topsoil and planting of the appropriate native species of trees, shrubs and grasses.

(4)

Preserving the significant natural features of the site, such as stonewalls, rock outcrops, wetlands, prominent tree stands, and vistas.

(5)

The area between the buildings and the street shall be landscaped in a way to provide visual interest, with a mixture of grass, different species of shrubs, trees, ground cover, annuals and perennial plants, except for walks, drives, flagpoles, and other landscaping and ornamentation.

(6)

Buffer strips of 50 feet shall be necessary when the site is abutting a residential zone. If existing vegetation does not provide an adequate buffer, the area shall be supplemented with hardy indigenous plant material, shrubs and trees.

(7)

Low-impact stormwater design best management practices shall be an integral part of all drainage and landscaping plans.

Pedestrian access. On-site pedestrian walkways shall be provided between parking areas and the building, as well as a walkway across the frontage of the lot along the public street that terminates at the abutting property line. Sidewalks shall be six feet wide and set back 10 feet from the curbline of a public street; however, the Commission may vary these standards based on site conditions and the ability to make linkages to other sidewalks. The applicant is to provide site interior walkways that link street/drive walks with existing or future multimodal sidewalk/trail system.

Utilities. All developments shall provide underground utilities in both public and private extensions of said utilities. All developments shall provide proper design and construction of cable, electrical and phone lines, natural gas, community septic systems, sanitary sewers, public water supply, and stormwater management system. Switching-gear cabinets, transformers and similar aboveground utility equipment shall be installed as shown on the site development plan, and a proper landscaping plan shall be submitted to screen these structures from view from abutting property and the public street.

Sewage disposal.

(1)

The Commission shall not approve any special permit or site plan application unless and until the Commission has been provided with a positive tentative staff determination from the applicable governing authority with respect to the compliance of the proposed sewage disposal system with applicable statutory and regulatory requirements and/or from the Marlborough Water Pollution Control Authority if the site is to be serviced by sanitary sewers or a community septic system.

(2)

Additionally, if the application proposes a community sewage disposal system, as a condition to any approval granted by the Commission, the applicant shall present to the Commission acknowledgement from the Marlborough Water Pollution Control Authority that it has approved an operation and maintenance agreement, including an escrow account for the maintenance and repair of said community sewage disposal system.

Water supply.

(1)

The Commission shall not approve any special permit or site plan application unless and until the Commission has been provided with:

(a)

If the proposed water system is not a community water system as defined by the State Department of Health and State Department of Utility Control, a letter of approval for the well location from the Chatham Health District; or

(b)

If the proposed water system is a community water system as defined by the State Department of Health and State Department of Utility Control, a letter from the exclusive service area provider acknowledging the submission of the application and its interest in ownership of said system, together with a Phase I-A approval from the State Department of Public Health and State Department of Public Utilities Control for all water supply wells in accordance C.G.S. § 16-262m(a) prior to the close of the public hearing.

(2)

Any approval granted by the Commission shall be conditioned upon receipt by the Commission of a Phase I-B approval from the State Department of Public Health and State Department of Public Utilities Control prior to issuance of any building or zoning permits for the construction of any buildings.

Stormwater management.

(1)

Purpose is to establish stormwater management requirements and controls to protect and safeguard the quality of the groundwater and surface water resources of Marlborough and to reduce adverse impacts associated with increases in peak rates of stormwater runoff.

(2)

Objective.

(a)

Incorporate decentralized stormwater management systems in any new development designs;

(b)

Minimize the increases in peak rates of stormwater runoff from any development in order to reduce flooding, siltation and stream bank erosion, and to maintain the integrity of stream channels and downstream drainage structures;

(c)

Minimize the increase in non-point-source pollution caused by stormwater runoff from development which would otherwise degrade local groundwater and surface water quality;

(d)

Minimize the total volume of surface water runoff which flows from any specific site during and following development to not exceed the predevelopment hydrologic regime to the maximum extent practicable;

(e)

Reduce stormwater runoff rates and volumes, soil erosion and non-point-source pollution wherever possible through stormwater management controls and to ensure that these management controls are properly maintained and designed to minimize potential threats to public safety.

(3)

Design and performance criteria. In order to prevent the adverse impacts of stormwater runoff, the Commission has developed a set of performance standards that must be addressed in the design of any new site development plan or modification to an existing site development plan that disturbs 5,000 square feet or more of area.

(a)

All stormwater runoff generated from new development shall not discharge stormwater runoff directly into a natural wetlands system, water body, municipal drainage system or abutting property without adequate pretreatment;

(b)

A vegetative separation shall be maintained to provide a disconnection between impervious surfaces and the natural wetland systems of the site and abutting sites;

(c)

All stormwater best management practices shall be designed to minimize the need for maintenance while maintaining water quality discharge treatment standards;

(d)

All site development plans shall be designed to minimize the need for stream bank/channel protection for the receiving natural system, but when required shall include provisions to prevent erosion and scouring of the stream bank/channel;

(e)

The design of all stormwater best management practices shall convey stormwater runoff in a manner to allow for the maximum removal of pollutants and reduction in flow velocities;

(f)

Stormwater discharges from land uses or activities with a higher potential pollutant loading may require the use of specific pretreatment structural methods and pollution prevention practices;

(g)

All site development plans shall include the design of stormwater detention or retention facilities to attenuate the increase in peak rates of stormwater runoff for the two-, five-, ten-, twenty-five- and one-hundred-year twenty-four-hour-duration storm events to provide for a zero post-development increase whenever practical.

(4)

Sensitive waters and wetlands: enhanced criteria.

(a)

Stormwater discharges to critical areas with sensitive resources, such as the Blackledge River, Dickinson Creek, Lyman Brook, Fawn Brook, Flat Brook, Lake Terramuggus and their contiguous wetlands, may be subject to additional performance criteria or may need to utilize or restrict certain stormwater management practices. Land development that discharges to sensitive waters and wetlands as noted above shall meet enhanced criteria. These may include but are not limited to:

[1]

Nutrient sensitive waters. Enhanced control of nutrients and sediment removal for stormwater discharges shall be required.

[2]

Cold-water fisheries. Techniques to control temperature increases from stormwater discharges into these streams and water bodies shall be required.

[3]

Groundwater. Enhanced recharge and pretreatment of stormwater discharges shall be required to protect groundwater supplies.

[4]

Wetlands. Controls to minimize impacts to the natural or predevelopment wetland hydrology, including limiting adverse fluctuations in surface water and groundwater elevations.

(b)

In these cases, the Commission may require additional storage capacity, treatment, filtering, infiltration or other mitigation techniques. The use of nonstructural practices shall be used to the maximum extent practical to meet enhanced criteria. In making its determination to apply enhanced criteria, the Commission shall consider the cumulative impacts of the site development plan.

(5)

Stormwater management plan requirements.

(a)

All stormwater management plans shall include measures to capture and treat stormwater runoff in accordance with the guidelines outlined in the most recent version of the Connecticut DEEP Stormwater Quality Manual and to incorporate low-impact development design elements to the extent that is practical.

(b)

No application for a development involving any site development plan will be approved by the Commission unless it includes a stormwater management plan detailing how the stormwater runoff and associated water quality impacts resulting from the development will be controlled and managed during and after construction. The plan must be prepared by an appropriate design professional.

(c)

The Commission may impose additional requirements deemed reasonable and necessary to control the volume, timing, rate and/or quality of runoff if the hydrologic, geologic, topographic or land use conditions warrant greater control than provided by the applicant. Further, the Commission may restrict the use of certain BMPs and may require pretreatment to exceed the minimum standards established in the most recent version of the Connecticut DEEP Stormwater Quality Manual.

(6)

Compliance with federal and state regulations. All stormwater facilities and conveyance systems shall be designed in compliance with all applicable Town, state and federal laws and regulations. It shall be the applicant's sole responsibility to identify and obtain all required permits prior to the start of any construction.

(7)

Protection of public health, safety and general welfare. The design of stormwater BMPs shall consider public health, safety and general welfare. These considerations shall include, but not be limited to: preventing flooding of buildings, structures and travelways; preventing long-term standing water in and near drainage facilities; minimize the creation of mosquitoes' breeding pools; preventing attractive nuisance conditions and dangerous conditions due to stormwater depth or velocity and/or access to drainage structures, including inlet and outlet openings. In addition, designs shall not result in the creation of aesthetic nuisances due to excessive slopes, cuts and fills, lack of suitable native landscaping and other similar conditions that would detract from the appearance of the surrounding environment.

(8)

Natural resource inventory.

(a)

Stormwater management designs shall include an inventory of important natural resources features on the site, and these features shall be shown on the stormwater management plan. Protection and/or conservation of the site's natural features shall be a part of the stormwater management plan.

(b)

The plan shall identify important natural features identified through a natural resources inventory that includes but shall not be limited to the following: natural drainage features, riparian buffers, wetlands, steep slopes, soils with high infiltration capacity, significant forest cover, significant trees and natural communities, including the presence of any threatened and/or endangered species.

(9)

Site design feasibility report.

(a)

Stormwater management practices for a site shall be selected on the basis of the physical characteristics of the site. The design professional shall submit a report outlining the stormwater practices options, including low-impact alternatives, that were considered and those that were chosen for the design based on the evaluation and analysis of site opportunities and constraints. Among the factors that should be considered:

[1]

Depth to groundwater/ledge.

[2]

Hydrologic functions.

[3]

Contributing drainage area.

[4]

Site vegetation.

[5]

Soil characteristics.

[6]

Topography.

[7]

Location in relation to environmentally sensitive features.

(b)

A soils report based on on-site boring logs or soil test pit data shall be submitted with all designs. The number and location of soil borings/test pits and associated soil testing shall be that which is necessary to determine the suitability and distribution of soil types present at the location of the proposed stormwater measures as shown on the site development plan.

(10)

Infiltration. All stormwater designs shall include infiltration for any new site development unless the site design feasibility report and associated soils report demonstrate that the physical characteristics of the site are not suitable. Low-impact design elements utilized for infiltration of discharge into a natural system shall utilize native plant species.

(11)

Overland flood routes.

(a)

Overland flood-routing paths shall be provided to safely convey stormwater runoff from the one-hundred-year, twenty-four-hour-duration storm event to receiving water resource or stormwater BMP with adequate hydraulic capacity, such that the runoff is contained within a drainage easement for the flood-routing path that does not cause flooding of buildings and abutting properties.

(b)

There shall be an allowance in all designs for a minimum of one foot of freeboard for all flood-conveyance systems and flood-control structures.

(12)

Stormwater conveyance. Stormwater conveyance systems shall be designed to:

(a)

Maximize the flow path from inflow to outflow points;

(b)

Include protection of inlet and outlet structures;

(c)

Provide for the elimination of or protection from erosive velocities; and

(d)

Utilize infiltration systems where applicable.

(13)

Velocity dissipation. Devices and techniques to reduce stormwater velocities and prevent erosion shall be placed at discharge outlet locations and along or within the full length of any outlet channels to convey and discharge peak design flows in a manner that will not result in scouring or surface erosion, including receiving streams or channels or wetlands, so that the natural physical and biological characteristics and functions of the receiving waters are maintained and protected.

(14)

Landscaping/planting plan.

(a)

All stormwater management designs shall include a detailed landscaping plan that identifies the types (both common and botanical names), locations, sizes and total number of all proposed plantings. Planting notes and details shall also be provided as well as a maintenance and management plan to ensure the long-term viability of all plantings. In addition, the landscaping plan shall include a stabilization schedule for the revegetation of all disturbed areas of the site. Any area of land from which the natural vegetative cover has been either partially or wholly cleared or removed by development activities shall be seeded with temporary vegetation within seven days after the suspension of grading work which is expected to last a period of 30 days or more. Permanent vegetation shall be fully established by the date of substantial completion of construction.

(b)

Following the first year after the establishment of permanent vegetation and the completion of all landscaping plantings, an inspection shall be conducted by the Town to confirm their health and survival. Should any permanent vegetation or plantings be determined to be dead or dying following the one-year period, then they shall be revegetated or replaced. A second inspection shall then be conducted by the Town one year from any subsequent revegetation or replanting.

(15)

Nonstructural stormwater practices. To the extent that they are feasible, the use of nonstructural stormwater treatment practices are required and shall be selected and designed using the appropriate criteria from the most recent version of the Connecticut DEEP Stormwater Quality Manual or other appropriate low-impact design manuals acceptable to the Commission.

(16)

Structural stormwater practices. All structural stormwater management facilities shall be selected and designed using the appropriate criteria from the most recent version of the Connecticut DEEP Stormwater Quality Manual. For other structural stormwater controls not included in the Connecticut DEEP Stormwater Quality Manual or for which pollutant removal rates have not been provided, the effectiveness and pollutant removal of the structural control must be documented through prior studies, literature reviews, or other means acceptable to the Commission before approval of any design utilizing such structural stormwater controls.

(17)

Discharge to municipal stormwater system. If any stormwater runoff from a new or modified site development plan is discharged to a municipal separate storm sewer system (MS4) or other publicly, municipally or privately owned storm sewer system, the applicant must demonstrate that the existing storm sewer system has adequate excess hydraulic capacity to convey both increases in peak discharge flow rates and in runoff volumes. In addition, all such discharges shall conform to all the requirements contained in the applicable general permit for the discharge of stormwater and dewatering wastewaters from construction activities, the general permit for the discharge of stormwater associated with industrial activity, or the general permit for the discharge of stormwater associated with commercial activity, as originally issued and reissued. All new or modified site development shall also conform in all respects to the Town of Marlborough Illicit Discharge Detection and Elimination Ordinance, as amended (Chapter 301, Article I, of the Town Code).

(18)

Operation, inspection and maintenance plan agreement and schedule.

(a)

An enforceable operation, inspection and maintenance plan agreement and schedule shall be executed to ensure that the stormwater management plan facilities function as designed and approved. The agreement shall designate the responsible party for the long-term maintenance of the approved stormwater management facilities and include a provision passing the responsibility for such maintenance to successors in title. This agreement shall include easements to the Town allowing access to all stormwater management plan facilities at reasonable times for periodic inspection by the Town and/or its agents to ensure that the facilities are being properly maintained and in good working order. Said easements shall be executed and recorded in the Marlborough Land Records with filing of the final endorsed plan.

(b)

The design and planning of all stormwater management plan facilities shall include detailed inspection procedures and frequencies, maintenance plans and schedules, as well as repair procedures to ensure their continued long-term function. These items shall identify the components of the stormwater management system that need to be inspected and maintained, provide a maintenance schedule for each facility and the equipment necessary to perform that maintenance. Provisions for the periodic review and evaluation of the effectiveness of the maintenance program and the need for revisions or additional maintenance procedures shall be included in the plan.

(c)

All stormwater management facilities must undergo, at a minimum, an annual inspection to document maintenance and repair needs and to ensure compliance with the requirements of the Connecticut DEEP Stormwater Quality Manual and any additional conditions assigned by the Commission. Any maintenance and/or repair needs found must be addressed in a timely manner by the owner and a reinspection made confirming the completion of the identified items. The owner shall submit to the Commission annually a copy of the inspection report and, if necessary, any reinspection reports. If the responsible party fails or refuses to fully address all items identified in an inspection report after 30 days' notice from the Commission of such failure to comply, the Commission shall commence enforcement action to achieve compliance.

(19)

Substantive changes to plan. No changes shall be made to an approved stormwater management plan without review and written approval by Town staff or if any such changes are determined to be substantive by the Commission. Additional data may be requested to allow for a complete review and evaluation of proposed changes to ensure compliance with the required discharge standards.

Decision criteria.

The site and all buildings, structures and uses shall be accessible for fire, police and other emergency vehicle service, which shall be accomplished through the review and report submitted by the Town Fire Marshal.

(b)

The site and all buildings, structures and uses shall comply with the State Building Code, specifically in regard to the requirements for handicapped access.

(c)

Parking, loading facilities, traffic circulation within the site, and entrance and exit driveways shall be adequately and properly located for maximum pedestrian and vehicular safety.

Landscaping on the site shall comply with the intent and the standards of Article XIII, and all refuse collection areas, parking, service and loading areas shall be suitably screened and/or enclosed by plantings, wall and fencing from the adjacent areas and public rights-of-way.

(e)

The stormwater drainage systems shall be designed to minimize soil erosion and to prevent off-site impacts and in compliance with the requirements of Subsection K above. The Commission may require that the overall drainage systems shall be designed such that the runoff rate outside of the development does not exceed the rate which existed before development and the use of low-impact development stormwater management best practices.

(f)

Due consideration to the Plan of Conservation and Development, as amended.

(g)

The design of the site, building, landscaping and other features are in accordance with the criteria of Subsections D through J of this section.

Performance/maintenance bond.

(1)

A performance bond shall be posted in an amount to be determined by the Commission based on a review of Town staff recommendations for the current construction costs of all proposed site improvements shown on the approved site development plan and all sediment and erosion control measures, site restoration, and landscape/planting plan improvements, plus a contingency allowance of 20%. Posting of the performance bond and a bond agreement shall be executed prior to the endorsement of the record plan and the commencement of any construction activity. No bond will be released in whole or in part for any portion of the stormwater management system until an as-built plan demonstrating substantial conformance with the approved stormwater management plan has been submitted and approved by the Commission.

(2)

The bond shall be posted with the Town in accordance with the approved site plan for an initial period of three years and include two one-year automatic renewals. Copies of these bond forms can be obtained from the office of the Planning and Development Director. The bond shall be in the form of a certified check payable to the Town of Marlborough, a savings passbook with a signed withdrawal slip for a joint account in the name of the Town and applicant, or an irrevocable letter of credit from a bank maintaining offices in Hartford, Middlesex, New London and/or Tolland Counties.

(3)

A maintenance bond, equal to at least 20% of the amount of the original performance bond amount, shall be held by the Commission for a period of one year following the approval of the as-built plan. At the discretion of the Commission, the maintenance bond period may be extended for an additional one-year period due to poor vegetative growth, structural failures, or other similar matters that impact the proper function and performance of stormwater management facilities, survival of the landscaping, or other compliance with the original approval.

Record drawings and bond release.

(1)

Prior to the issuance of a certificate of occupancy and compliance and prior to the release of the performance bond to a maintenance bond, the Commission requires that one Mylar and two paper copies of the as-built record drawing are submitted to the Commission for the finding of compliance with the approval granted.

(2)

On the finding of compliance of the original approval, the Commission will sign the Mylar as-built record drawing, and the applicant shall record it at his expense in the office of the Marlborough Town Clerk prior to issuance of the certificate of occupancy.

Conditional approvals. If the application is approved with stipulations and/or conditions, one Mylar and three paper copies of the revised plans and other pertinent documents necessary to satisfy the conditions of approval shall be submitted to, approved by and signed by the Commission within 90 days from the date of the conditional approval. The Commission may grant, upon written request of the applicant, a maximum of two ninety-day extensions. Any plan or permit not approved and signed by the Commission within the required time frames shall become null and void. Final approval shall be obtained at such time as the plans are signed by the Commission.

Filing with the Town Clerk. Upon final approval, the approved site development plan application, with the signed Mylar site development plan, shall be recorded by the record landowner at his expense in the office of the Marlborough Town Clerk. Any site development plan not so recorded within 90 days following the date of final approval and signature by the Commission shall become null and void.

Site plan becomes void.

(1)

All work associated with the approved site development plan shall be completed within three years from the date that the site development plan has been filed with the Marlborough Town Clerk. The Commission may grant, upon written request of the applicant, a maximum of two one-year extensions. In all cases, all work in connection with such site development plan shall be completed within five years after the plan has been filed with the Marlborough Town Clerk.

(2)

Failure to complete all work within such five-year period shall result in automatic expiration of the approval of the site development plan. For the purposes of this section of the chapter, "work" shall mean all physical improvements required by the approved plan.

Conditional record drawing approval. During the period beginning December 1 and ending April 1 or due to seasonal or weather-related conditions, the Commission and the ZEO, where authorized, may at their discretion issue conditional as-built record drawing approval where plantings, earth grading and seeding have not been completed. The conditional as-built record drawing approval may be issued for a period not to exceed 180 days. Upon written request by the applicant, completion of the remaining site work and submission of the record drawing, the Commission may release the remainder of the bond and the Chairman shall sign the record drawing.

Amendments. Construction and site improvements shall be completed in strict compliance with the permit approved by the Commission. However, amendments to an approved site plan may be made, provided that an application is submitted to and approved by the ZEO or by the Commission as provided in this subsection. If the ZEO determines that the construction or plan modifications are of a minor nature and do not materially affect the permit, the ZEO may approve a set of modified site plans and construction drawings. If the ZEO determines that the construction or plan modifications are a significant amendment, the Commission may approve a set of modified site plans and construction drawings.

Conditions for revocation. A site development plan may be subject to revocation by the Commission, upon initiation of the process by the ZEO, if any condition or safeguard imposed by the Commission upon land, buildings, structures and/or uses for said site development plan are not strictly adhered to by the applicant and/or landowner. The ZEO shall adhere to the procedures detailed in Article XV of this chapter whenever a site development plan must be revoked.

Waiver of site plan requirements.

(1)

In addition to uses and activities specifically exempted from site plan requirements by this chapter, the Commission may waive requirements for a site plan if it determines that a proposed activity will not affect existing traffic circulation or result in an increase in the need for parking, nor will it entail any significant exterior change to a building or site, nor will the new activity have an impact substantially different from the existing use from which the change is requested. A request for a waiver of site plan requirements will be submitted in writing by the property owner or owner's agent at the time of application. A Commission decision to waive site plan requirements may be made based on informal discussion of the activity at a regular or special Commission meeting.

(2)

Also, a partial waiver of site plan information requirements may be granted to avoid unnecessary delay and expense for an applicant whose proposed activity is minor in nature and limited in its impact on the surrounding area. The Commission may, at its sole discretion, exempt any application from specific information requirements as set forth in this section. The exemption may be approved if the Commission finds that the information would not aid the Commission in its determination of the application's compliance with this chapter. A request for a partial waiver of site plan requirements will be submitted in writing by the property owner or owner's agent at the time of application.
