Off-street automobile parking and loading and unloading spaces shall be provided, as specified in this chapter, for uses and structures hereafter established.

Any building or use that is subsequently enlarged shall meet the off-street parking and loading and unloading space requirements of this chapter for the original building plus the addition made.

(Ord. 265A (part), 2001)

The following are required plan and design standards for off-street parking and loading and unloading spaces:

A.

Required Area for Each Parking Space. Each automobile parking space shall be not less than nine feet wide and nineteen feet deep. Adequate interior driveways shall connect each parking space with a public street. A maximum of one foot six inches of the required nineteen feet may overhang a grassed area. This overhang cannot be over a sidewalk or right-of-way and must be arranged in such a way as to allow adequate front-to-front parking.

B.

Interior Driveways. Interior driveways, when used with ninety degree angle parking, shall be at least twenty-four feet wide; when used with a sixty degree angle parking at least twelve feet wide. When used with parallel parking or when there is no parking, interior driveways shall be at least ten feet wide for one-way traffic and at least twenty feet wide for two-way traffic.

C.

Improvement of Off-Street Parking Lots. All off-street parking lots, whether public or private, for more than five vehicles shall meet the following standards:

1.

They shall be graded to insure proper drainage, surfaced with concrete or asphalt at least two inches thick, installed on an approved base and maintained in good condition free of weeds, dust, trash and debris.

2.

High intensity lighting facilities shall be so arranged that the source of any light is concealed from public view and from adjacent residential properties and does not interfere with traffic.

3.

They shall not be used for the sale, repair, dismantling or servicing or storing of any vehicle, equipment, materials or supplies.

4.

Each parking space shall be clearly demarcated by a painted stripe no less than three inches wide running the length of each of the longer sides of the space or by curbing or by other acceptable method which clearly marks and delineates the parking space within the parking lot.

D.

Location of Required Off-Street Parking Spaces on Other Property. If the required automobile off-street parking spaces cannot reasonably be provided on the same lot on which the principal use is conducted, such spaces may be provided on other off-street property lying not more than four hundred feet from the main entrance to the principal use. In this situation, the applicant shall submit, with his/her application for a building permit or occupancy permit, an instrument duly executed and acknowledged, which accepts the permanent availability of such off-street parking facilities to serve his/her principal use.

E.

Sharing of Required Off-Street Parking Spaces. One-half of the off-street parking spaces required by a use whose peak attendance will be at night or on Sundays may be assigned to a use that will be closed at night or on Sundays.

F.

Off-Street Loading and Unloading Spaces. Off-street loading and unloading spaces shall have access from a public alley or, if there is no alley, from a public street. The space shall be so located that it causes a minimum of interference with the free movement of vehicles and pedestrians over a street, sidewalk or alley.

(Ord. 265A (part), 2001)

The following are the minimum number of off-street parking spaces required. For uses not specifically listed, the off-street parking requirements shall be those of the most similar use:

(Ord. 265A (part), 2001)

A.

Purpose. The purpose of this section is to promote health, safety, and welfare within the city and its watershed by minimizing the harms and maximizing the benefits, through provisions designed for allowance of pervious pavement systems as part of a stormwater management plan. The city recognizes that stormwater runoff has been traditionally treated as a by-product of development to be disposed of as quickly and efficiently as possible. The result has often been increased flooding, degradation of surface and subsurface water quality, soil erosion and sedimentation, and a failure to capitalize on the benefit of creative stormwater management. It is the intent of this section to encourage the use of best management practices (BMPs) which are structural, vegetative, or managerial practices designed to treat, prevent, or reduce degradation of water quality due to stormwater runoff. All development projects subject to review under the requirements of this section shall be designed, constructed, and maintained using BMPs to prevent flooding, protect water quality, reduce soil erosion, maintain and contribute to the aesthetic values of the project.

B.

General Requirements for Pervious Pavement Systems for Non-Single Family Residential Uses.

1.

Pervious pavement systems shall be designed to manage stormwater through the prevention of flooding and the degradation of water quality related to stormwater runoff and soil erosion from proposed development.

2.

Pervious pavement systems shall be designed by a registered professional engineer or landscape architect and installed by a contractor qualified in the particular system used.

3.

The pervious pavement designer shall include maintenance instructions to the property owner along with a maintenance schedule.

4.

Pervious pavement systems generally consist of a pavement layer and a detention layer. The pavement layer must be capable of supporting vehicular or pedestrian traffic and have sufficient porosity to allow rainwater to percolate into the layer below. The detention layer typically consists of gravel or crushed stone and has sufficient voids to store water after a storm until such time as the water can infiltrate into the soil below. In some areas the infiltration rate of the natural soil below the pavement system is sufficient to justify eliminating the detention layer.

5.

At a minimum, a pervious pavement system must be designed to adequately accommodate a NRCS two-year twenty-four-hour design storm. The storage capacity of the pervious pavement system, which includes the pavement layer and the detention layer, must be designed to have sufficient detention capacity such that the stormwater will infiltrate into the soil below and can accommodate a second NRCS two-year twenty-four-hour design storm within five days of the previous storm.

6.

Pervious concrete systems shall be designed in accordance with ACI Specification 522.1 or equivalent standard.

7.

Pervious concrete shall be installed by a qualified National Ready Mixed Concrete Association (NRMCA) certified pervious concrete installer or craftsman or equivalent who must be onsite to oversee the each placement crew during all pervious concrete placements.

C.

For Development of New Properties.

1.

Property is considered new property if the property proposed for development has no existing construction. Such properties shall:

a.

Use pervious paving material for a minimum of ten percent of the parking spaces if parking requires a minimum of two hundred fifty spaces such that one-hundred percent of the total area covered by pervious pavement systems designed to allow the infiltration of water may be considered pervious.

b.

Provide a comprehensive stormwater management plan that emphasizes infiltration and onsite retention of stormwater for at least the NRCS two-year design storm event through a combination of methods including buffer strips, swales, rainwater gardens, pervious pavement systems and other low impact development methods. The stormwater management plan must be designed by a registered professional engineer or landscape architect and installed as designed by a qualified contractor.

c.

A survey showing exact dimensions and arrangement of pervious and impervious surfaces.

D.

For Re-development of Existing Properties.

1.

Property is considered existing property if the property proposed for re- development has existing improvements.

2.

Existing properties that do not exceed the maximum allowed impervious surface for new properties shall meet the development requirements for new properties upon the placement of additional building(s), a minimum twenty-five percent expansion to an existing building, or parking area.

3.

A survey shall be submitted showing calculations of the exact dimensions of all existing impervious surfaces and of the lot before and after completion of the project.

4.

In replacing existing impervious surfaces with surfaces designed to be pervious, the applicant must give priority to replacing those surfaces closest to natural bodies of water (lakes, ponds, rivers, streams or ocean) or those surfaces where the replacement is most likely to improve stormwater management.

E.

Site Design.

1.

Rooftop runoff shall be directed to pervious pavement systems, open channels, or vegetated areas to avoid roadways or the stormwater conveyance system.

2.

Create a variable width, naturally vegetated or pervious buffer system along all drainageways that also encompasses critical environmental features such as the one hundred-year floodplain, steep slopes, and wetlands.

3.

Minimize clearing and grading of woodlands and native vegetation to the minimum amount needed to build lots, allow access, and provide fire protection.

4.

Conserve trees and other vegetation at each site by planting additional vegetation, clustering tree areas, and promoting the use of native plants.

5.

The use of pervious pavement systems for paved areas is encouraged.

6.

New constructed stormwater outfalls to public waters must provide for filtering or settling of suspended solids and skimming of surface debris before discharge. Pervious pavement systems may be used as one method to achieve this requirement.

F.

Maintenance Inspection.

1.

The city reserves the right of access for periodic preventative maintenance in accordance with the recorded stormwater facility maintenance agreement.

2.

Inspection reports shall be maintained by the city for all stormwater management systems.

3.

Inspection reports for stormwater management systems shall include the following:

i.

The date of inspection;

ii.

Name of inspector;

iii.

The condition of:

a.

Vegetation or filter media;

b.

Fences or other safety devices;

c.

Spillways, valves, or other control structures;

d.

Embankments, slopes, and safety benches;

e.

Reservoir or treatment areas;

f.

Inlet and outlet channels or structures;

g.

Underground drainage;

h.

Sediment and debris accumulation in storage and forebay areas;

i.

Any other item that could affect the proper function of the stormwater management system.

4.

Description of needed maintenance. After notification is provided to the owner of any deficiencies discovered from an inspection of a stormwater management system, the owner shall have thirty days to correct the deficiencies. The city shall then conduct a subsequent inspection to ensure completion of the repairs. Should the owner fail to correct the deficiencies, the owner will be issued a citation for violation of the city code.

G.

Reserved.

H.

Reserved.

I.

Applicability.

1.
