Sandy Springs City Zoning Code

ARTICLE 9

- ENVIRONMENTAL PROTECTION

Sec. 9.1.1. - Wetland Regulations

A.

National Wetland Inventory Maps The National Wetland Inventory Maps, prepared by the United States Fish and Wildlife Service, show the general locations of wetlands and should be consulted by persons contemplating activities in or near wetland areas. These maps should be used as a guide only. Field verification is required to determine the existence or absence of any jurisdictional waters.

B.

Plans Design professionals, after consulting the National Wetland Inventory maps and conducting appropriate field studies, must indicate wetlands or jurisdictional waters on plans required for land disturbance permit applications.

C.

Design Professional Statement Prior to the issuance of a land disturbance permit, the design professional who prepared the required plans accompanying the permit application, must add a statement to the plan sheet indicating land disturbance and the Statement must read as follows:

Wetland certification:

The design professional, whose seal appears hereon, certifies the following: (1) the National Wetland Inventory maps have been consulted and appropriate field studies have been conducted; and, (2) the appropriate plan sheet [__] DOES/[__] DOES NOT (mark appropriate box) indicate wetlands as shown on the maps; and, (3) if wetlands are indicated, the land owner or developer has been advised that land disturbance of protected wetlands or jurisdictional waters must not occur unless the appropriate federal wetlands alteration ("Section 404") permit has been obtained.

D.

ACOE Coordination The issuance of Land Disturbance Permits by the City may be coordinated with the U.S. Army Corps of Engineers Section 404 permitting process. If the "wetland certification" above indicates the presence of wetlands or jurisdictional water as shown on the NWI generalized wetlands maps or by field study, a land disturbance permit that identifies alterations of designated wetlands or jurisdictional waters may not be issued by the City until a Section 404 Permit or Letter of Permission is obtained from the U.S. Army Corps of Engineers.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.2.1. - Findings and Purpose

A.

Minimize land development within such buffers and setbacks by establishing buffer and setback requirements and by requiring authorization for any such activities.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.2.2. - Applicability

A.

Generally This Division applies to all land development activity on property containing a state waters buffer as defined in Article 12 and an additional impervious surface setback. These requirements are in addition to, and do not replace or supersede, any other applicable buffer and setback requirements established under state law, and approval of or exemption from these requirements does not constitute approval of or exemption from buffer and setback requirements established under state law or from other applicable local, state or federal regulations.

B.

Legal Nonconforming Structures This Division does not apply to the following existing structures:

1.

Work consisting of the repair or maintenance of any lawful use of land that is zoned and approved for such use on or before December 12, 2005.

2.

Existing development and ongoing land disturbance activities including but not limited to existing agriculture, silviculture, landscaping, gardening and lawn maintenance, except that new development or land disturbance activities on such properties will be subject to all applicable buffer and setback requirements.

3.

A variance from the requirements of the Sandy Springs portion of any state waters buffer (which includes the 50-foot vegetative buffer or 75-foot impervious surface setback (see Sec. 9.2.3) is not required for:

a.

Repair or replacement in kind of any legally approved principal structure located in the buffer that existed prior to December 12, 2005, provided that the footprint of the pre-2005 structure is not exceeded and engineering analysis indicates that no rise in flood elevation will occur. All required permits are still necessary prior to construction.

b.

Repair or replacement of any structure or improvement located in the 75-foot impervious surface setback and approved prior to December 12, 2005, provided that the area of imperviousness in square feet remains the same or is reduced, and that the new structure or improvement is not located any closer to the 50-foot vegetative buffer than the existing one.

c.

Removal of a principal or accessory structure or otherwise reducing the amount of impervious surface in the State waters buffer or the setback, provided the State waters buffer is restored using native vegetation in accordance with revegetation standards in "Buffer Zone," starting on page 6-15 of the GSWCC's Manual for Erosion and Sediment Control in Georgia: 2016 Edition.

d.

All required permits are still necessary prior to demolition and/or construction.

C.

Exemptions The following specific activities are exempt from this Division. Exemption of these activities does not constitute an exemption for any other activity proposed on a property.

1.

Activities for the purpose of building 1 of the following:

a.

A stream crossing by a driveway, transportation route or utility line;

b.

Public water supply intake or public wastewater outfall structures;

A.

Minimum Requirements This Division is not intended to interfere with, abrogate or annul any other chapter, rule or regulation, statute or other provision of law. The requirements of this Division should be considered minimum requirements, and where any provision of this Division imposes restrictions different from those imposed by any other chapter, rule, regulation or other provision of law, whichever provisions are more restrictive or impose higher protective standards for human health or the environment are considered to take precedence.

B.

Additional standardsthat apply and will be enforced by the City are as follows:

1.

Metropolitan River Protection Act (MRPA) and Chattahoochee Corridor Plan:

a.

Requires a 50-foot (undisturbed) vegetative buffer;

b.

Requires a 150-foot impervious surface setback on the Chattahoochee and its impoundments; and

c.

Requires a 35-foot undisturbed vegetative buffer (all measured from the edge of the water) on perennial tributary streams in a corridor extending 2,000 feet from either bank of the river and its impoundments.

d.

The corridor extends from Buford Dam to the downstream limits of the Atlanta region (Douglas and Fulton Counties). Streams in the basin of the Corridor are required to be protected by buffers, but no required width is specified. (O.C.G.A. § 12-5-440 et seq.)

2.

DNR Part 5 Criteria for small (under 100 square miles) water supply watersheds:

a.

Authorized under O.C.G.A. § 12-2-8, these criteria require 100-foot undisturbed buffers and 150-foot setbacks on all perennial streams within 7 miles upstream of a public water supply reservoir or public water supply intake.

b.

Beyond 7 miles, the required buffer is 50 feet and the required setback is 75 feet. Equivalent protection measures may be adopted with approval from the State Department of community affairs and the Department of natural resources (DCA and DNR).

3.

DNR Part 5 Criteria for river protection authorized under the Metropolitan River Protection Act, these criteria require a 100-foot buffer along rivers with average annual flows of greater than 400 cubic feet per second (cfs) excepting the portion of the Chattahoochee referenced in subsection (1) of this Section. The buffer is measured from the top of the stream bank.

4.

Other such state and federal regulations as may be adopted from time to time. While the requirements of this Division are intended to apply to all state waters in the City, special conditions may exist that require greater protection. Nothing in this Division should be construed as preventing the establishment of wider and/or more restrictive buffers and setbacks as required under any other existing or future legislation. In addition, nothing in this Division should be construed as preventing the establishment of wider buffers or setbacks for purposes of protecting greenspace, preserving habitat or other goals that may not be specifically mandated by legislation.

2.

Removal of a hazardous tree, provided the owner of the property must immediately notify the City Arborist of the removal of the tree and provide documentation that the removed tree was a hazardous tree. Hazardous tree means a tree that is at risk for failure because it is dead or structurally defective, and where that failure could result in personal injury or property damage.

C.

Site/Tree Conservation Plan

1.

As part of the application for a Tree Removal Permit, a Site/Tree Conservation Plan is required in conjunction with any activity requiring the issuance of a building permit (other than a building permit for a deck, open air patio, fence or interior renovations), demolition permit, land disturbance permit, or erosion and grading permit by the City.

2.

Whenever an application for a building permit or land disturbance permit requires a Site/Tree Conservation Plan, the process is as follows:

a.

Concurrently with the building permit, or land disturbance permit application, the applicant must submit a Site/Tree Conservation Plan prepared by a qualified professional for review by the City Arborist.

b.

The Site/Tree Conservation Plan must document the following:

i.

Tree species, DBH, critical root zone, and location of all existing trees and existing tree canopy on the property;

ii.

The location, species, and caliper size of all proposed mitigation planting trees;

iii.

The location of all proposed building construction and land development activities, including grading, drainage, proposed utility locations and all proposed tree protection measures;

iv.

All trees proposed for removal; and

v.

Calculation of the tree canopy on the property prior to and following the implementation of the tree removal/replacement activity set forth in the Site/Tree Conservation Plan.

c.

If the proposed tree removal causes the canopy to fall below the minimum canopy requirement, the applicant is required to:

i.

Pay into the Tree Bank for the deficient canopy as set forth in Sec. 9.3.8 D; and

ii.

Install trees of a similar species to bring the site into compliance with the minimum canopy requirement.

d.

The Site/Tree Conservation Plan must document standard details for tree protection and tree planting in compliance with the Technical Manual.

e.

The Site/Tree Conservation Plan must document compliance with the parking and landscape requirements of this Development Code in compliance with the Technical Manual.

f.

The Site/Tree Conservation Plan must document all Boundary Trees, their critical root zones, and the calculated percentages of impact to the critical root zones.

D.

Replanting Location Incentive When meeting canopy requirements with replanted trees, the Site/Tree Conservation Plan must document compliance with the following:

1.

Each large canopy tree planted along the street frontage receives mitigation credit for 1.25 trees.

2.

Each large canopy tree planted between 50 feet and 75 feet of a stream buffer receives mitigation credit for 1.25 trees.

E.

Payment and Assurances Required A Site/Tree Conservation Plan approval will not be issued until both:

1.

Payment of any required amounts by cashier's check have been received by the Sandy Springs Tree Bank; and

2.

The City has been provided adequate assurances of any required canopy replacement (such as a tree planting schedule).

F.

Field Verification

1.

The qualified professional submitting the Site/Tree Conservation Plan must field verify the accuracy of the Site/Tree Conservation Plan prior to submittal.

2.

A certificate of occupancy may be issued after final site inspection by City Staff to verify compliance.

A.

Boundary Tree means a tree 10 inches DBH or larger located on a property adjacent to a permitting property whose critical root zone or canopy extends into that permitting property.

B.

Where a Tree Removal Permit is required for a Boundary Tree, the City Arborist must determine whether the proposed land disturbance or construction activity will deprive the Boundary Tree of continued viability.

1.

If there is not sufficient evidence to show that the proposed activity will deprive the Boundary Tree of continued viability, the Tree Removal Permit may be issued allowing the proposed activity.

2.

If there is sufficient evidence to show that the proposed activity will deprive the Boundary Tree of continued viability, the Tree Removal Permit must not be issued in a manner allowing the proposed activity relating to the Boundary Tree.

C.

If the City Arborist determines that it is uncertain whether the proposed land disturbance or construction activity will deprive the Boundary Tree of continued viability, prior to the issuance of a Tree Removal Permit allowing the proposed activity relating to the Boundary Tree:

1.

The applicant must provide 2 or more estimates from professionals that are determined to be sufficient to offset the removal and replacement costs of the Boundary Tree, and an average will be used to determine the amount of funds the applicant must provide into an account established by the City. Notice must be provided to the property owner whose property contains the Boundary Tree and must include notice of the deposited funds and a copy of this Section.

2.

In establishing the escrow amount required pursuant to Sec. 9.3.8 F, the proposed replacement tree upon which payment is computed must be comparable to the Boundary Tree in species and size potential, be ecologically compatible with the intended growing site, and at maturity fully mitigate the loss of the entire canopy area of the Boundary Tree.

3.

For the purposes of this Section, credit will be granted to applicants for the entire tree canopy of a Boundary Tree protected, as calculated pursuant to the Technical Manual.

8.

Generally recognized good forestry practices;

9.

Canopy coverage;

10.

Necessary grading; or

11.

The construction of structures allowed in setback areas.

C.

For removal or destruction of trees approved pursuant to paragraph A. above, on property not meeting the canopy requirements, or on property on which removal of the Setback Tree will cause the tree canopy to fall below the canopy requirements, the Setback Tree must be replaced by the planting of new trees comparable to the Setback Tree in species and canopy potential within the minimum required setback of the property.

D.

If the City Arborist determines that replacement of the Setback Tree is not practical based upon: (1) the size and configuration of the Property; or (2) undue hardship for the applicant, payment may be made into the Sandy Springs Tree Bank in lieu of replacement planting. The compensation for the lost tree canopy below the canopy requirements is calculated on a square foot lost/replaced basis as set forth in the canopy and cost assignment table contained in Sec. 9.3.8 D.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

h.

Other factors creating undue hardship for the applicant; or

3.

If the Landmark Tree's health is poor or the Landmark Tree is dead.

C.

All Landmark Trees removed pursuant to Sec. 9.3.3 A. must be replaced by the planting of new trees on the property of a comparable species and with a canopy potential of 150% of the canopy of the Landmark Tree to foster the enhancement of the tree canopy. Canopy mitigation is computed using the actual measured canopy of the Landmark Tree.

D.

If the City Arborist determines that replacement of the Landmark Tree is not practical based upon the size and configuration of the property, payment may be made into the Sandy Springs Tree Bank in lieu of replacement planting. The compensation for the lost tree canopy below the canopy requirements is calculated on a square foot lost/replaced basis as set forth in the canopy and cost assignment table contained in Sec. 9.3.8 D.

E.

In calculating a Tree Removal Permit, the preservation of existing Landmark Trees in the side, front and rear yards will receive 1.25 square feet of mitigation credit for each lot of canopy planted.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.3.7. - Protected Tree

A.

Protected Tree means a tree 18 inches DBH or larger, other than a Landmark Tree or Setback Tree, in fair or better condition.

B.

The destruction or removal of a Protected Tree on any property must comply with the Site/Tree Conservation Plan provisions of Sec. 9.3.3 C.

C.

The removal or destruction of Protected Trees on property not meeting the canopy requirements, or that will cause the tree canopy to fall below the canopy requirements, is permitted only if the Protected Trees are:

1.

Located within the building footprint of the proposed construction, as permitted by the City; or

2.

Outside of the permitted building footprint, and the City Arborist determines that the permitted land disturbance or construction activity will require the removal of the Protected Tree based on the provisions of Sec. 9.3.5 B.

D.

The City Arborist may decide to approve the removal of a Protected Tree by weighing the following factors in order to determine the extent of the impact of the removal of the Protected Tree upon adjacent properties and only allow such removal if it is determined that such impact is minimal:

1.

The size and configuration of the property;

2.

The physical condition of the tree;

3.

Cost effectiveness of potential alternatives to tree removal;

4.

Whether the tree contributes to meeting any of the requirements set forth in this Article or other requirements set forth by the City;

5.

Generally recognized good forestry practices; or

6.

Other factors creating undue hardship for the applicant.

E.

For removal or destruction of trees approved pursuant to paragraphs C. and D. above, on property not meeting the canopy requirements, or on property on which removal of the Protected Tree will cause the tree canopy to fall below the canopy requirements, the Protected Tree must be replaced by the planting of new trees comparable to the Protected Tree in species and canopy potential.

F.

If the City Arborist determines that replacement is not practical based upon:

1.

The size and configuration of the property;

2.

Unavoidable site modifications resulting from grading, utility work, and construction activities that will result in destruction or irreparable damage to the tree, or wherein site plan modifications to prevent destruction or irreparable damage to the tree are impossible or unduly burdensome on the applicant;

The tree canopy of common areas appurtenant to the property; or

4.

Other factors creating undue hardship for the applicant including but not limited to: pedestrian or vehicle traffic on and adjacent to the property; the configuration of buildings, structures and utilities on or adjacent to the property; cost effectiveness of potential replacement; whether the tree contributes to meeting any of the requirements set forth in this Division or other requirements set forth by the City; or generally recognized good forestry practices;

5.

Then payment may be made into the Sandy Springs Tree Bank in lieu of replacement planting. The compensation for the lost tree canopy below the canopy requirements is calculated on a square foot lost/replaced basis as set forth in the canopy and cost assignment table contained in Sec. 9.3.8 D.

6.

The compensation for the lost tree canopy below the canopy requirements is calculated on a square foot lost/replaced basis as set forth in the canopy and cost assignment table contained in Sec. 9.3.8 D.

7.

All trees removed pursuant to this Section must be replaced by the planting of new trees on the property of a comparable species and canopy potential.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.3.8. - Administration

A.

Technical Manual The Technical Manual was prepared in conjunction with this Article and, as it exists and may be amended from time to time, it is incorporated here, and a copy of it is maintained in the office of the City Clerk. If any term of the Technical Manual is deemed to conflict with the terms of this Article, the terms of this Article control.

B.

Appeals

1.

Any applicant under this Article aggrieved by an action of the City Arborist, or any adjacent property owner directly impacted by a decision made under this Article, may appeal and be heard by the Board of Appeals in accordance with the rules and regulations as set forth by this Article and the Board. See Sec. 11.6.3.

2.

Appeals may only be granted for errors of interpretation, application, or where the unique natural features of the site are such that it is impractical or impossible to apply the terms, conditions or standards of this Article, resulting in an undue hardship to the property owner.

C.

Establishment of Tree Bank

1.

There is hereby established a Sandy Springs Tree Bank for the maintenance and disbursement of funds required to be paid pursuant to the terms of this Article.

2.

Where it is determined by the City Arborist that payment into the Sandy Springs Tree Bank is required by this Article, the required funds must be paid to the Sandy Springs Tree Bank prior to issuance of any related permit.

3.

Funds maintained in the Sandy Springs Tree Bank are administered by the Director pursuant to the rules and regulations regarding the funds as established by the Sandy Springs City Council for the purposes of replacing tree canopy or canopy preservation.

D.

Cost Assignment

1.

For the purposes of calculation of required payment into the Sandy Springs Tree Bank, an assessed value of $5,000.00 per 1,000 square feet of canopy will be used when canopy replacement cannot be achieved by replanting on the site.

a.

Large Canopy Trees are calculated as 1,000 square feet credit.

b.

Medium Canopy Trees are calculated as 500 square feet credit.

c.

Small Canopy Trees are calculated as 250 square feet credit.

2.

When proposed construction causes the canopy to fall below the minimum canopy requirement, an assessed value of $1,200.00 per 1,000 square feet of canopy is used to determine the payment for the deficient canopy.

3.

For any unauthorized tree removal, an assessed value of $7,500.00 per 1,000 square feet of canopy removed will be used to determine payment into the Sandy Springs Tree Bank.

E.

Potentially Damaged Trees—Escrow Fund

1.

Where the City Arborist determines that due to approved construction or land disturbance activity an applicant may remove a tree pursuant to the terms of this Article, and the applicant is required to pay for the lost tree canopy of the removed tree, the applicant may, at its election, propose alternative construction or site design methods to attempt to preserve the continued viability of the tree. Should the City Arborist determine that the proposed alternative construction or site design methods will reasonably result in the survival of the tree, that portion of the funds required to pay for the lost tree canopy of the tree pursuant to this Article must be paid into an escrow fund maintained by the City.

2.

After 3 years from the date of receiving a certificate of occupancy or certificate of completion, the applicant has the right to petition the City Arborist for the return of all escrow funds held for the protection of the tree. Within 30 days of the petition, the City Arborist will make a determination as to whether the tree has failed to survive or is in a state of irreversible decline due to the permitted activity. Should the City Arborist determine that the tree has survived and is not in a state of irreversible decline, the funds must be paid to the applicant. Should the City Arborist determine that the tree has failed to survive or is in a state of irreversible decline, the escrow must be transferred into the Sandy Springs Tree Bank.

3.

If funds are required to be paid into escrow pursuant to paragraph 1. above, at any time prior to a determination authorizing the return of the escrow funds to the applicant pursuant to paragraph 4. below, the property owner (petitioner) whose property contains the tree may petition the City Arborist for the payment of the escrow funds to be used for the removal and replacement of the tree on the grounds that the permitted activity has caused the tree to fail to survive or be in a state of irreversible decline.

4.

Upon receipt of such petition, notice of the petition is provided to the applicant hereunder at the address provided at the time of the tree removal permit application, or at any alternative address subsequently designated by the applicant to the City Arborist in writing, via first class and certified mail, within 30 days of mailing of the notice. The City Arborist will make a determination as to whether the tree has failed to survive or is in a state of irreversible decline due to the permitted activity. Notice of the decision is provided to the petitioner and the applicant by certified and first class mail as set forth in this paragraph. Either party may appeal the City Arborist's determination pursuant to this Article. Should the City Arborist determine that the tree failed to survive or is in a state of irreversible decline due to the permitted activity, and no appeal has been timely filed, or the applicant has fully exhausted his or her appellate rights, the escrow funds will be paid to the petitioner to offset any costs incurred in removal and replacement of the tree. The petitioner's rights pursuant to this Section may not be exercised more than once in any 18-month period.

5.

Any funds not collected by either an affected property owner or the applicant within a period of 6 years of the establishment of the escrow fund are deposited in the Sandy Springs Tree Bank.

6.

No party is entitled to receive interest on any escrow funds required pursuant to the provisions of this Article.

F.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.4.1. - Purpose

A.

The purpose of this Division is to protect topographic features and natural grades in order to prevent 1 or more of the following negative impacts:

1.

Erosion affecting the structural integrity of steep slopes and natural grades.

2.

Stormwater and erosion-related impacts on adjacent properties.

3.

Stormwater and erosion-related impacts to environmentally sensitive areas.

4.

Increased stormwater velocity due to loss of vegetation.

5.

Decreased groundwater recharge due to changes in site hydrology.

6.

Loss of natural or topographic features that contribute substantially to the natural beauty and visual quality of the community.

B.

The standards of this Division do not apply to steep slopes in the CS- or Perimeter Center Districts.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.4.2. - Standards

A.

Definition For purposes of this Division, "slope" means the ratio of elevation change to horizontal distance, expressed as a percentage. Slope is computed by dividing the vertical distance ("rise") by the horizontal distance ("run"). For example, a 3-foot rise in a 20-foot run results in a 15% slope.

B.

Applicability All construction, including renovations and additions, must comply with the requirements of this Division.

C.

Designation on Plans Moderate and steep slopes of 1,000 square feet and greater in area must be designated on any Land Disturbance Permit or Building Permit application.

D.

Moderate Slopes of 15% and Up to 35% Building and site preparation may occur upon demonstration of specialized site design techniques and approaches that meet the requirements in F. below.

E.

Steep Slopes of 35% or Greater These areas are generally unsuitable for development. Land disturbance must not exceed ¼ of the area containing slopes of 35% or greater in areas of 1,000 square feet or more, except that where an existing lot of record does not have a reasonable building site with less than 35% slope or natural grade, the Director may approve the site, subject to any necessary mitigation measures.

F.

Construction Techniques Construction activities on slopes of 15% or greater must comply with the following:

1.

All plans must show provisions for reducing and minimizing stormwater runoff during construction on steep slopes and cut and fill slopes.

2.

All swales and all slopes must be provided temporary or permanent stabilization with ground cover sufficient to restrain erosion as soon as practicable, but in any event, within 7 calendar days of any phase of grading.

3.

All other disturbed areas must be provided temporary or permanent stabilization with ground cover sufficient to restrain erosion as soon as practicable, but in any event, within 14 calendar days of termination or completion of any phase of grading.

4.

Prior to issuance of a certificate of occupancy, vegetation must be reestablished.

5.

Where irrigation is not provided, the exposed soil must be planted with species that survive without irrigation.

6.

Vegetative ground cover or any alternative cover (rock, masonry, or similar materials) must be maintained in perpetuity.

G.

Grading In order to protect trees and vegetation on sites, and to protect the character of the neighborhood, the following limits on grading are required.

1.

Mitigation measures Any grading in side building setbacks in RE-, RD- and RU- Districts, must be mitigated following the measures listed below.

a.

For each tree of 10 inches DBH or greater removed or damaged by grading in the side setback, 1 tree must be planted;

b.

If no tree of 10 inches DBH or greater is removed or damaged, at least 1 large canopy shade tree must be planted for every 1,000 square feet of area disturbed in the side setback;

c.

Replacement tree species must be of comparable canopy size at maturity as those of the trees removed or damaged;

d.

Replacement trees must be at least 2 inches caliper at time of planting;

e.

Planting must take place in the graded area. If this is not possible, the replacement trees may be located elsewhere on the property. If this is not possible, recompense provisions (see Sec. 9.3.8) of the Tree Ordinance apply;

f.

This mitigation is required in addition to any other provisions of the Tree Ordinance, including those that apply to Setback Trees (see Sec. 9.3.5).

2.

Common Side and Side Street Grading Setback

a.

In all RE- Districts, grading may encroach up to 10 feet into the required side building setbacks.

b.

In all RD- and RU- Districts, grading may encroach into the required side building setbacks.

3.

Rear Grading Setback

a.

In all RE- Districts, no grading is allowed within 20 feet of the rear lot line.

b.

In the RD-27, RD-18, and RD-15 Districts, no grading is allowed within 15 feet of the rear lot line.

c.

In the RD-12, RD-9, RD-7.5, and RU- Districts, no grading is allowed within 10 feet of the rear lot line.

4.

Common, Side Street, and Rear Grading Setback Exceptions

The following may be granted exceptions from common, side street, and rear grading setback requirements:

a.

Director Review and Inspection: Where a side or rear yard is the only feasible option for a construction entrance, grading disturbance may be approved by the Director, so long as the width of the area of activity within the buffer does not impact an existing tree with a 15-inch DBH or greater and is replaced with a mitigation zone. The Director shall conduct a physical inspection of the work site where alternative access is being requested.

b.

Mitigation Zone: Regardless of the original state of the affected grading buffer area, mitigation in the form of plantings, a mix of evergreen and deciduous trees, and shrubs is required per the prescription provided:

i.

The mitigation zone must be at least 5 feet deep bordering the entire project area within the grading setback;

ii.

Evergreen trees spaced at 1 per 25 linear feet, minimum of 1, full to the ground and at least 6 feet tall at the time of planting;

iii.

Understory trees spaced at 1 per 25 linear feet, minimum of 1, with a minimum caliper of 2 inches;

iv.

Shrubs spaced 8 per 25 linear feet, minimum of 8, with a minimum size of 3; and

v.

Additional BMPs determined to be necessary by the Director to preserve existing vegetation.

5.

In all districts, resulting graded slopes must not exceed 3 feet (horizontal) to 1 foot (vertical). Steeper slopes may be approved by the Director upon certification of stability by a soils engineer or geologist.

6.

Any unauthorized clearing and grading must replant the cleared area according to the requirements of the Mitigation Zone in Sec. 9.4.2 G.4.c.

H.

Variance from Standards In granting a variance from the standards of this Section, the Board of Appeals may determine that some features or areas may not be disturbed. These include, but are not limited to:

1.

Large stands of trees;

2.

Areas containing state waters, floodplain, or wetlands or in the Nancy Creek Declared Sensitive Area;

3.

Rock outcroppings; and

4.

Slopes of 35% or greater.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.4.3. - Retaining Walls

Where retaining walls are necessary, they are limited as follows:

A.

Design

1.

Height

a.

Measurement Total retaining wall height is considered to be:

i.

Structure Height (Building Code)—The vertical distance measured from the bottom of the footing to the top of the wall at the same section.

ii.

Exposed Height (Zoning Code)—The vertical distance measured from finished grade at the bottom of the front (exposed) side of the wall to the top of the wall at the same section.

b.

Maximum Height

i.

Retaining Walls

Up to 6 feet in exposed wall height as a single wall in RE-, RD-, and RU zoning districts. Up to 8 feet in exposed wall height as a single wall in all other districts, except when abutting a Protected Neighborhood.

ii.

Tiering Walls

Over the maximum exposed wall heights for a single wall in each district, requires tiering. Each wall tier must adhere to the maximum wall height as described above. See Sec. 9.4.3 A.2.a below for horizontal spacing requirements.

iii.

Interior Facing

a)

Retaining walls that are entirely interior facing are permitted up to 12 feet in exposed height. This includes Wing Walls (retaining wall extensions from the building foundation walls that allow daylighting of a basement and/or egress from a basement) that are inward facing and finished with a permitted material finish.

1)

Setbacks

If they are to encroach into building setbacks and are entirely inward facing the walls must be a maximum of 6 feet in exposed wall height and meet the retaining wall setback requirements found in Sec. 9.4.3 C. below.

2)

Length

Maximum length of any wall exceeding the normal maximum retaining wall height is 36 feet (based on the maximum 3:1 allowable grading slope). Any length of wall past 36 feet must meet the requirements of a retaining wall as outlined above.

b)

The Director may permit retaining walls that are entirely interior facing on campuses with civic or institutional uses to have up to 24 feet in exposed height. This includes wing walls that are finished with a permitted material finish.

iv.

Exterior Facing

Retaining walls that are exterior facing and at least 100 feet from a street lot line and 75 feet from a common lot line are permitted up to 12 feet in exposed height. This includes wing walls that are finished with a permitted material finish.

c.

Elevation Marks Wall height elevations marks must be demonstrated on the grading plan through callouts at various locations along the retaining wall using the following or similar: TW-Top of Wall; BW-Bottom of Wall (at Grade); BF-Bottom of Footing.

d.

Fences or Walls on Top of Retaining Walls Fences or walls extending on top of retaining walls are subject to the requirements of Sec. 8.3.10.

Within Setbacks at Any Point

For retaining walls and tiered wall systems which begin in or enter into a building setback, the combined height of the retaining wall and an extension fence or wall must not exceed the maximum height of retaining walls, per Sec. 9.4.3 D. and Sec. 9.4.3 E, unless required in order to comply with applicable life safety regulations. In a tiered retaining wall system, an extension fence or wall must only be located on the highest tier.

2.

Spacing

a.

Distance Retaining walls must be separated horizontally by at least 4 feet from other retaining walls (measured from the back of the lower wall to the front of the upper wall). This horizontal separation area must be graded to capture stormwater and not sloped such that stormwater will run off. The stormwater design must be included with the retaining wall permit plans.

b.

Design Each tier between retaining walls, and any retaining wall within a building setback, must be vegetated and maintained with a mix of native, evergreen, and deciduous shrubs, 1 shrub every 4 linear feet to be approved by the City Arborist.

The Director may waive this landscaping standard for retaining walls that slope back (are inward facing) and contain natural planting.

3.

Materials

a.

Material and Finish All retaining walls must be finished with stucco, brick, or stone. No beveled modular block, plain unfinished concrete masonry units, or other similar materials are allowed.

Retaining walls may utilize alternative facing elements such as evergreen vegetation as approved by the Director. The wall must be located only in side or rear yards and be planted with native, non-invasive evergreen planting material. The plant growth must be at a minimum 50% of the wall's face prior to closeout of the permit and maintained throughout all seasons.

Retaining walls which meet the description of Garden Walls below in Sec. 9.4.3 B.3. may also use cross ties, landscape timbers, or similar as a wall, material finish.

B.

Permits and Other Requirements

1.

All Retaining walls, whether in commercial or residential settings, regardless of height:

Require a retaining wall permit and a professional engineer's certification of the design of the wall if they support a surcharge.

Surcharge is defined as any vertical load imposed on the retained soil that may impose a lateral force in addition to the lateral earth pressure of the retained soil. Examples of surcharges include:

a.

Sloping retaining soil;

b.

Structure footings supported by the retained soil;

c.

Adjacent vehicle loads supported by the retained soil;

d.

Tiered retaining wall systems.

2.

Permit Required All retaining walls over 4 feet in structure height require a retaining wall permit and a professional engineer's certification of the design of the wall.

3.

No Permit Required All other retaining walls 4 feet or less in structure height do not require a permit but do require an indemnification letter. This includes retaining walls otherwise known as "Garden Walls" which for the purposes of this Code have a maximum exposed height of 3 feet, while also not exceeding 4 feet of structure height.

4.

Global Stability During the permit review process, the global stability of any series of tiered retaining walls will be reviewed. A safety factor of at least 1.5 is required.

5.

Impact Where a retaining wall or wing wall might impact (either visually or structurally) an existing structure, adjacent property, street, buffer, utility, or other similar significant interest, the Director and/or Building Official may require plans, details, cross-sections, and professional engineer calculations beyond those cited in this Section.

C.

Setback Encroachment In order to protect trees and vegetation on sites and the character of the neighborhood, the following setback standards apply:

1.

Side Setbacks In the side building setbacks:

a.

In all RE- Districts, retaining walls may encroach up to 10 feet into required side building setbacks.

b.

In all RD- Districts, retaining walls may encroach up to half the depth of the required side building setbacks.

c.

In all RU- Districts, no encroachment for retaining walls is allowed into the required side building setbacks.

d.

All other districts, retaining walls may encroach into the side setbacks so long as they are at least 3 feet from the vertical plane of any lot line.

2.

Rear Setbacks In the rear building setbacks:

a.

In all RE- districts, no retaining walls are allowed within 20 feet of the rear lot line.

b.

In the RD-27, RD-18, and RD-15 districts, no retaining walls are allowed within 15 feet of the rear lot line.

c.

In the RD-12, RD-9, RD-7.5, and RU- districts, no retaining walls are allowed within 10 feet of the rear lot line.

d.

All other districts, retaining walls may encroach into the rear setbacks so long as they are at least 3 feet from the vertical plane of any lot line.

D.

Maintenance and Replacement Existing legally permitted and constructed retaining walls may be maintained and repaired, provided the maintenance and repair is structurally sound and does not result in an increase in the height of the wall above grade.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023; Ord. No. 2024-06-10, § I, 6-18-2024)

Sec. 9.5.1. - In General

A.

Purpose The purpose of this Division is to protect, maintain, and enhance the public health, safety, environment, and general welfare and to minimize public and private losses due to flood conditions in flood hazard areas, as well as to protect the beneficial uses of floodplain areas for water quality protection, streambank and stream corridor protection, wetland preservation, and ecological and environmental protection by provisions designed to:

1.

Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;

2.

Restrict or prohibit uses which are dangerous to health, safety and property due to flooding or erosion hazards, or which increase flood heights, velocities, or erosion;

3.

Control filling, grading, dredging, and other development which may increase flood damage or erosion;

4.

Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards to other lands;

5.

Limit the alteration of natural floodplains, stream channels, and natural protective barriers which are involved in the accommodation of floodwaters; and

Failure to submit certification or failure to make the corrections required hereby is cause to issue a stop work order for the project.

E.

Appeals and Variances The following variance and appeals procedures will apply to an applicant who has been denied a permit for a development activity, or to an owner or developer who has not applied for a permit because it is clear that the proposed development activity would be inconsistent with the provisions of this Division.

1.

The Board of Appeals will hear and decide requests for appeals or variances from the requirements of this Division. At a minimum, such procedures will include notice to all affected parties and the opportunity to be heard.

2.

The Board of Appeals will hear and decide appeals when it is alleged an error in any requirement, decision, or determination is made by the Director in the enforcement or administration of this Division. At a minimum, such procedures will include notice to all affected parties and the opportunity to be heard.

3.

Variances may be issued for the repair or rehabilitation of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance issued is the minimum necessary to preserve the historic character and design of the structure.

4.

Variances may be issued for development necessary for the conduct of a functionally dependent use, provided the criteria of this Division are met, no reasonable alternative exists, and the development is protected by methods that minimize flood damage during the base flood and create no additional threats to public safety.

5.

Variances will not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.

6.

In reviewing such requests, the Board of Appeals will consider all technical evaluations, relevant factors, and all standards specified in this and other sections of this Division.

7.

Conditions for variances:

A variance is issued only when there is:

a.

A finding of good and sufficient cause;

b.

A determination that failure to grant the variance would result in exceptional hardship; and

c.

A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, or the creation of a nuisance.

8.

The provisions of this Division are minimum standards for flood loss reduction, therefore, any deviation from the standards must be weighed carefully. Variances will only be issued upon determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

9.

Any applicant to whom a variance is granted is given written notice specifying the difference between the base flood elevation and the elevation of the proposed lowest floor and stating that the cost of flood insurance resulting from the lowest floor elevation being placed below the base flood elevation will be commensurate with the increased risk to life and property, and that such costs may be as high as $25.00 for each $100.00 of insurance coverage provided.

10.

The Director will maintain the records of all variance actions, both granted and denied, and report them to the Georgia Department of Natural Resources and the Federal Emergency Management Agency upon request.

11.

Any person requesting a variance must, from the time of the request until the time the request is acted upon, submit such information and documentation as the Board of Appeals will deem necessary for the consideration of the request.

12.

Upon consideration of the factors listed in this Section and the purposes of this Division, the Board of Appeals may attach such conditions to the granting of variances as it deems necessary to further the purposes of this Division.

13.

Variances will not be issued "after the fact."

c.

Changing the flow characteristics as to the depth and velocity of the waters of the base flood or future-conditions flood as they pass both the upstream and the downstream boundaries of the property; or

d.

Creating hazardous or erosion-producing velocities, or resulting in excessive sedimentation.

3.

Any development within any area of special flood hazard or area of future-conditions flood hazard allowed under Sec. 9.5.3 C.1 must also meet the following conditions:

a.

Compensation for storage capacity must occur between the average groundwater table elevation and the base flood elevation for the base flood, and between the average groundwater table elevation and the future-conditions flood elevation for the future-conditions flood, and lie within the boundaries of ownership of the property being developed and is within the immediate vicinity of the location of the encroachment. Acceptable means of providing required compensation:

i.

Include lowering of natural ground elevations within the floodplain, or lowering of adjoining land areas to create additional floodplain;

ii.

Storage. In no case will any required compensation be provided via bottom storage or by excavating below the elevation of the natural (pre-development) stream channel unless such excavation results from the widening or relocation of the stream channel;

b.

Cut areas are stabilized and graded to a slope of no less than 2%;

c.

Effective transitions are provided such that flow velocities occurring on both upstream and downstream properties are not increased or decreased;

f.

Any significant physical changes to the base flood floodplain is submitted as a conditional letter of map revision (CLOMR) or conditional letter of map amendment (CLOMA), whichever is applicable. The CLOMR submittal is subject to approval by the Department using the FEMA community concurrence forms before forwarding the submittal package to FEMA for final approval. The responsibility for forwarding the CLOMR to FEMA and for obtaining the CLOMR approval is the responsibility of the applicant. Within 6 months of the completion of development, the applicant must submit as-built surveys and plans for a final letter of map revision (LOMR).

D.

Engineering Study Requirements for Floodplain Encroachments An engineering study is required, as appropriate to the proposed development activities on the site, whenever a development proposes to disturb any land within the future-conditions floodplain, except for a residential single-lot development on streams without established base flood elevations and floodways. This study is prepared by a licensed professional engineer and made a part of the application for a permit. This information is submitted to and approved by the Department prior to the approval of any permit which would authorize the disturbance of land located within the future-conditions floodplain. Such study must include all requirements specified in the Sandy Springs Technical Manual:

1.

Description of the extent to which any watercourse or floodplain will be altered or relocated as a result of the proposed development;

2.

Step-backwater analysis, using a FEMA-approved methodology approved by the Department. Cross sections (which may be supplemented by the applicant) and flow information will be obtained whenever available. Computations will be shown duplicating FIS results and will then be rerun with the proposed modifications to determine the new base flood profiles and future-conditions flood profiles;

3.

Floodplain storage calculations based on cross sections (at least 1 every 100 feet) showing existing and proposed floodplain conditions to show that base flood floodplain and future-conditions floodplain storage capacity would not be diminished by the development;

4.

The study must include a preliminary plat, grading plan, or site plan, as appropriate, which must clearly define all future-conditions floodplain encroachments.

E.

Floodway Encroachments Located within areas of special flood hazard are areas designated as floodways. A floodway may be an extremely hazardous area due to velocity floodwaters, debris or erosion potential. In addition, floodways must remain free of encroachment in order to allow for the discharge of the base flood without increased flood heights. Therefore, the following provisions will apply:

1.

Encroachments are prohibited, including earthen fill, new construction, substantial improvements, accessory structures, fences or other development within the regulatory floodway, except for activities specifically allowed in subsections 2. and 3. below.

2.

Encroachments for bridges, culverts, roadways and utilities within the regulatory floodway may be permitted provided it is demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the encroachment will not result in any increase to the pre-project base flood elevations, floodway elevations, or floodway widths during the base flood discharge. A licensed professional engineer must provide supporting technical data and certification thereof; and

3.

Encroachments for fences having sufficient open area to permit the free flow of water and/or debris may be permitted within a Future Conditions Floodway provided it does not encroach into the Floodway as determined by a FEMA approved FIS as shown on the current effective FIRM maps. Fences within the Future Conditions Floodway shall meet the following requirements:

a.

Open Area must be certified by a Professional Engineer to allow the free flow of water based on the flows as established by the City FIS determining the Future Condition floodway.

b.

Posts must be anchored to prevent flotation or dislodging. Anchoring shall be designed and certified by a Professional Engineer.

c.

No permit authorizing the fence shall be issued by the City until a no-rise certification is approved by the Department.

F.

Maintenance Requirements The property owner is responsible for continuing maintenance as may be needed within an altered or relocated portion of a floodplain on the property so that the flood-carrying or flood storage capacity is maintained. The City may direct the property owner, at no cost to the City, to restore the flood-carrying or flood storage capacity of the floodplain if the owner has not performed maintenance as required by the approved floodplain management plan on file with the Department.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023; Ord. No. 2025-05-04, § I, 5-6-2025)

13.

Other public utilities such as gas and electric systems must be located and constructed to avoid impairment to them, or public safety hazards from them during flooding;

14.

Any alteration, repair, reconstruction or improvement to a structure which is not compliant with the provisions of this Division is undertaken only if the nonconformity is not furthered, extended or replaced;

15.

If the proposed development is located in multiple flood zones or multiple base flood elevations cross the proposed site, the higher or more restrictive base flood elevation or future-condition elevation and development standards must take precedence;

16.

When only a portion of a proposed structure is located within a flood zone or the future conditions floodplain, the entire structure must meet the requirements of this Division; and

17.

Subdivision proposals and other proposed new development, including manufactured home parks or subdivisions, must be reasonably safe from flooding:

a.

All such proposals must be consistent with the need to minimize flood damage within the flood-prone area;

b.

All public utilities and facilities, such as sewer, gas, electrical, and water systems must be located and constructed to minimize or eliminate flood damage; and

c.

Adequate drainage must be provided to reduce exposure to flood hazards.

B.

Sec. 9.6.1. - Purpose

The purpose of this Division is to protect, maintain and enhance the public health, safety, environment and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased post-development stormwater runoff and non-point source pollution associated with new development and redevelopment by focusing on the types of frequently occurring storm events that generate the most water quality impacts. Proper management of post-development stormwater runoff will minimize damage to public and private property and infrastructure, safeguard the public health, safety, environment and general welfare of the public, and protect water and aquatic resources. This Division seeks to meet that purpose through the following objectives:

A.

Establish decision-making processes surrounding land development activities that protect the integrity of the watershed and preserve the health of water resources;

B.

Require that new development and redevelopment maintain the pre-development hydrologic response in their post-development state as nearly as practicable in order to reduce flooding, stream bank erosion, non-point source pollution and increases in stream temperature, and maintain the integrity of stream channels and aquatic habitats;

C.

Establish minimum post-development stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality and to preserve and/or restore natural hydrologic conditions on development sites;

D.

Establish design and application criteria for the construction and use of structural stormwater control facilities that meet the minimum post-development stormwater management standards;

E.

Encourage the use of nonstructural stormwater management and stormwater better site design practices, peak rate and/or runoff reduction, and the preservation of greenspace and other conservation areas, by establishing minimum post-development stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality. Coordinate site design plans, which include greenspace, with the City's greenspace protection plan;

F.

Establish provisions for the long-term responsibility of operation, inspection, maintenance and repair of private structural stormwater control facilities and private commitments for nonstructural stormwater management practices to ensure that they continue to function as designed, are maintained, and pose no threat to public safety or the environment;

G.

Establish administrative procedures for the submission, review, approval and disapproval of stormwater management plans, and for the inspection of approved active projects, and long-term compliance; and

H.

Protect public health and safety by reducing the risk of localized flooding and reducing the amount of runoff entering streets.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.6.12. - Performance Criteria

A.

For new developments, the following performance criteria will be applied to the area of the site impacted by the proposed work. For redevelopment, the following performance criteria will be applied to the area of the site impacted by the proposed work, provided that the impacted area does not exceed 35% of the previously developed area. If the impacted area exceeds 35% of the previously developed area, the following performance criteria will be applied to the entire development, including previously developed area:

1.

Water Quality/Runoff Reduction: All stormwater runoff generated from a site must provide runoff reduction of the first 1.2 inches of rainfall or must be adequately treated for water quality before discharge. With the exception of single lot residential developments that are not part of a common development, this must be accomplished by the use of Green Infrastructure Best Management Practices unless determined to be infeasible in accordance with Sec. 9.6.7 B.4 of this Code.

It will be presumed that a stormwater management system complies with this requirement if it satisfies the stormwater reduction criteria in this Section. However if any of the stormwater runoff volume generated by the first 1.2 inches of rainfall cannot be reduced or retained on site due to constraints such as a high water table, rock, low infiltration rates or the presence of a hotspot, the remaining volume must be increased by a multiplier of 1.2 and must be intercepted and treated in 1 or more stormwater management practices that provide at least an 80% reduction in total suspended solids loads in accordance with the following criteria:

a.

It is sized to treat the prescribed water quality treatment volume from the site, as defined in the Georgia Stormwater Management Manual;

b.

Appropriate structural stormwater controls or nonstructural practices are selected, designed, constructed or preserved, and maintained according to the specific criteria in the Georgia Stormwater Management Manual or constitutes an alternative practice responsibly designed and documented by the design professional to reproduce the intent of the Georgia Stormwater Management Manual; and

c.

Runoff from hotspot land uses and activities identified by the Department are adequately treated and addressed through the use of appropriate structural stormwater controls, nonstructural practices and pollution prevention practices.

2.

Stream Channel Protection Protection of stream channels from bank and bed erosion and degradation is provided by using all of the following 3 approaches:

a.

Preservation, restoration and/or reforestation (with native vegetation) of the applicable stream buffer;

b.

Twenty-four-hour extended detention storage of the 1-year, 24-hour return frequency storm event;

c.

Erosion prevention measures such as energy dissipation and velocity control.

d.

For redevelopment projects that create, add, or demolish and replace less than 5,000 square feet of impervious surface and meet the performance criteria of this Section, stream channel protection is not required.

3.

Overbank Flooding Protection

a.

Downstream overbank flood and property protection is provided by controlling (attenuating) the post-development peak discharge rate to the pre-development rate for the 25-year, 24-hour return frequency storm event. If control of the 1-year, 24-hour storm under subsection (a) of this Section is exempted, then peak discharge rate attenuation of the 2-year through the 25-year return frequency storm event must be provided. For redevelopment projects overbank flood and property protection must be provided by reducing the peak discharge rate up to the 25-year, 24-hour storm event in accordance with the following formula:

b.

%PIC/2 = %PDRR

c.

PIC = Predevelopment Impervious Cover

i.

PDRR = Peak Discharge Rate Reduction

d.

For sites where previous demolition has removed impervious surfaces, pre-development peak discharge rate calculations and percentage of impervious coverage must be calculated based on pre-demolition conditions. For sites that have been demolished and have remained fallow and stabilized with vegetation for a minimum of 5 years, they must be considered as having pre-development conditions of 20% impervious cover for purposes of calculating peak discharge rate reduction.

e.

For land development permitted after 2005 and served by appropriate stormwater management facilities, subsequent redevelopment of the same area is not required to further reduce the peak discharge rate, provided that the site continues to meet the reduction previously achieved.

f.

For redevelopment projects that create, add, or demolish and replace less than 5,000 square feet of impervious surface and meet the performance criteria of this Section, overbank flooding protection is not required.

4.

Extreme Flooding Protection

a.

Extreme flood and public safety protection is provided by controlling and safely conveying the 100-year, 24-hour return frequency storm event such that flooding is not exacerbated.

b.

For redevelopment projects that create, add, or demolish and replace less than 5,000 square feet of impervious surface and meet the performance criteria of this Section, extreme flooding protection is not required.

5.

Structural Stormwater Controls All structural stormwater management facilities are selected and designed using the appropriate criteria from the Georgia Stormwater Management Manual. All structural stormwater controls must be designed appropriately to meet their intended function. For other structural stormwater controls not included in the Georgia Stormwater Management 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 and receive approval from the Department before being included in the design of a stormwater management system. In addition, if hydrologic or topographic conditions, or land use activities warrant greater control than that provided by the minimum control requirements, the City may impose additional requirements deemed necessary to protect upstream and downstream properties and aquatic resources from damage due to increased volume, frequency, and rate of stormwater runoff or increased non-point source pollution loads created on the site in question. Applicants must consult the Georgia Stormwater Management Manual for guidance on the factors that determine site design feasibility when selecting and locating a structural stormwater control.

6.

Stormwater Credits for Nonstructural Measures The use of 1 or more site design measures by the applicant may allow for a reduction in the water quality treatment volume required under Sec. 9.6.12 A.1. The applicant may, if approved by the Department, take credit for the use of stormwater better site design practices and reduce the water quality volume requirement. For each potential credit, there is a minimum set of criteria and requirements that identifies the conditions or circumstances under which the credit may be applied. The site design practices that qualify for this credit and the criteria and procedures for applying and calculating the credits are included in the Georgia Stormwater Management Manual.

7.

Drainage System Guidelines Stormwater conveyance facilities, which may include but are not limited to culverts, stormwater drainage pipes, catch basins, drop inlets, junction boxes, headwalls, gutters, swales, channels, ditches, and energy dissipaters, are provided when necessary for the protection of right-of-way and private properties adjoining project sites and/or rights-of-way. Stormwater conveyance facilities that are designed to carry runoff from more than 1 parcel, existing or proposed, must meet the following requirements:

a.

Methods to calculate stormwater flows are in accordance with the stormwater design manual;

b.

All culverts, pipe systems and open channel flow systems are sized in accordance with the stormwater management plan using the methods included in the Georgia Stormwater Management Manual; and

c.

Design and construction of stormwater conveyance facilities are in accordance with the criteria and specifications found in the Georgia Stormwater Management Manual.

8.

Dam Design Guidelines Any land disturbing activity that involves a site that proposes a dam must comply with the Georgia Safe Dams Act of 1978 (O.C.G.A. § 12-5-370 et seq.) and rules for dam safety as applicable.

9.

Declared Sensitive Area Guidelines In accordance with the Georgia Stormwater Management Manual, Volume 2 Section 2.2.2.1, the City reserves the right to establish more stringent standards for sub-basin areas that may cause significant adverse water quality, quantity and discharge rates due to numerous small developments. The sub-basin areas must be Declared Sensitive Areas. Any development within a Declared Sensitive Area must comply with the design and construction standards as set forth in the Technical Manual Section 10.M.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.7.1. - Title and Findings

A.

Title This Division will be known as "The City of Sandy Springs Soil Erosion, Sedimentation and Pollution Control Ordinance."

B.

Findings The City of Sandy Springs finds that soil erosion and sediment deposition onto land and into water within the watersheds of the City are a result of failure to apply proper soil erosion and sedimentation control practices in land clearing, soil movement, and construction activities and that such erosion and sediment deposition result in pollution of state waters and damage to domestic, agricultural, recreational, fish and wildlife, and other resource uses. It is therefore declared to be the policy of the City of Sandy Springs and the intent of this Division to strengthen and extend the present erosion and sediment control activities and programs of the City of Sandy Springs and to provide for the establishment and implementation of a City-wide comprehensive soil erosion and sediment control program to conserve and protect the land, water, air, and other resources of the City of Sandy Springs.

Sec. 9.7.3. - Minimum Requirements

A.

General Provisions Excessive soil erosion and resulting sedimentation can take place during land-disturbing activities if requirements of the ordinance from which this Division derived and the NPDES general permit are not met. Therefore, plans for those land-disturbing activities that are not exempted by this Division will contain provisions for application of soil erosion, sedimentation and pollution control measures and practices. The provisions must be incorporated into the erosion, sedimentation and pollution control plans. Soil erosion, sedimentation and pollution control measures and practices must conform to the minimum requirements of Sec. 9.7.3 B. and Sec. 9.7.3 C. of this Division. The application of measures and practices will apply to all features of the site, including street and utility installations, drainage facilities and other temporary and permanent improvements. Measures must be installed to prevent or control erosion, sedimentation and pollution during all stages of any land-disturbing activity in accordance with requirements of this Division and the NPDES general permit.

B.

Minimum Requirements/BMPs

1.

Best management practices as set forth in this Section of this Division will be required for all land-disturbing activities. Proper design, installation, and maintenance of best management practices will constitute a complete defense to any action by the Director or to any other allegation of noncompliance with Sec. 9.7.3 B.2 or any substantially similar terms contained in a permit for the discharge of stormwater issued pursuant to O.C.G.A. § 12-5-30(f), the "Georgia Water Quality Control Act." As used in this Section, the terms "proper design" and "properly designed" mean designed in accordance with the hydraulic design specifications contained in the "Manual for Erosion and Sediment Control in Georgia" specified in O.C.G.A. § 12-7-6(b).

2.

A discharge of stormwater runoff from disturbed areas where best management practices have not been properly designed, installed, and maintained will constitute a separate violation of any land-disturbing permit issued by a local issuing authority or of any state general permit issued by the division pursuant to O.C.G.A. § 12-5-30(f), the "Georgia Water Quality Control Act," for each day on which such discharge results in the turbidity of receiving waters being increased by more than 25 nephelometric turbidity units for waters supporting warm water fisheries or by more than 10 nephelometric turbidity units for waters classified as trout waters. The turbidity of the receiving waters must be measured in accordance with guidelines to be issued by the Director, EPD. This paragraph will not apply to any land disturbance associated with the construction of single unit homes which are not part of a larger common plan of development or sale unless the planned disturbance for such construction is equal to or greater than 5 acres.

3.

Failure to properly design, install, or maintain best management practices will constitute a violation of any land-disturbing permit issued by a local issuing authority or of any state general permit issued by the division pursuant to O.C.G.A. § 12-5-30(f), the "Georgia Water Quality Control Act," for each day on which such failure occurs.

4.

The Director may require, in accordance with regulations adopted by the Board of Natural Resources, reasonable and prudent monitoring of the turbidity level of receiving waters into which discharges from land-disturbing activities occur.

5.

The Local Issuing Authority (LIA) may set more stringent buffer requirements than stated in Sec. 9.7.3 C.15 and Sec. 9.7.3 C.16, in light of O.C.G.A. § 12-7-6(c).

C.

The rules and regulations, ordinances, or resolutions adopted pursuant to O.C.G.A. § 12-7-1 et seq. for the purpose of governing land-disturbing activities will require, as a minimum, protections at least as stringent as the State general permit and best management practices, including sound conservation and engineering practices to prevent and minimize erosion and resultant sedimentation, which are consistent with, and no less stringent than, those practices contained in the "Manual for Erosion and Sediment Control in Georgia" published by the Georgia Soil and Water Conservation Commission as of January 1 of the year in which the land-disturbing activity was permitted, as well as the following:

1.

Stripping of vegetation, regrading and other development activities must be conducted in a manner so as to minimize erosion;

2.

Cut-fill operations must be kept to a minimum;

3.

Development plans must conform to topography and soil type so as to create the lowest practicable erosion potential;

4.

Whenever feasible, natural vegetation must be retained, protected and supplemented;

5.

The disturbed area and the duration of exposure to erosive elements must be kept to a practicable minimum;

6.

Disturbed soil must be stabilized as quickly as practicable;

7.

Temporary vegetation or mulching must be employed to protect exposed critical areas during development;

8.

Permanent vegetation and structural erosion control practices must be installed as soon as practicable;

9.

To the extent necessary, sediment in runoff water must be trapped by the use of debris basins, sediment basins, silt traps, or similar measures until the disturbed area is stabilized. As used in this paragraph, a disturbed area is stabilized when it is brought to a condition of continuous compliance with the requirements of O.C.G.A. § 12-7-1 et seq.;

10.

Adequate provisions must be provided to minimize damage from surface water to the cut face of excavations or the sloping of fills;

11.

Cuts and fills may not endanger adjoining property;

12.

Fills may not encroach upon natural watercourses or constructed channels in a manner so as to adversely affect other property owners;

13.

Grading equipment must cross flowing streams by means of bridges or culverts except when such methods are not feasible, provided, in any case, that such crossings are kept to a minimum;

14.

Land-disturbing activity plans for erosion, sedimentation and pollution control must include provisions for treatment or control of any source of sediments and adequate sedimentation control facilities to retain sediments on site or preclude sedimentation of adjacent waters beyond the levels specified in Sec. 9.7.3 B.2 of this Division;

15.

Except as provided in paragraph (16) of this Section, there is established a 25-foot buffer along the banks of all state waters, as measured horizontally from the point where vegetation has been wrested by normal stream flow or wave action, except where the Director, EPD determines to allow a variance that is at least as protective of natural resources and the environment, where otherwise allowed by the Director, EPD pursuant to O.C.G.A. § 12-2-8, where a drainage structure or a roadway drainage structure must be constructed, provided that adequate erosion control measures are incorporated in the project plans and specifications and are implemented; or along any ephemeral stream. As used in this provision, the term "ephemeral stream" means a stream: that under normal circumstances has water flowing only during and for a short duration after precipitation events; that has the channel located above the groundwater table year round; for which groundwater is not a source of water; and for which runoff from precipitation is the primary source of water flow, unless exempted as along an ephemeral stream, the buffers of at least 25 feet established pursuant to Part 6 of Article 5, Chapter 5 of Title 12, the "Georgia Water Quality Control Act," will remain in force unless a variance is granted by the Director, EPD as provided in this paragraph. The following requirements apply to any such buffer:

a.

No land-disturbing activities will be conducted within a buffer and a buffer must remain in its natural, undisturbed state of vegetation until all land-disturbing activities on the construction site are completed. Once the final stabilization of the site is achieved, a buffer may be thinned or trimmed of vegetation as long as a protective vegetative cover remains to protect water quality and aquatic habitat and a natural canopy is left in sufficient quantity to keep shade on the streambed; provided, however, that any person constructing a single unit residence, when such residence is constructed by or under contract with the owner for his or her own occupancy, may thin or trim vegetation in a buffer at any time as long as protective vegetative cover remains to protect water quality and aquatic habitat and a natural canopy is left in sufficient quantity to keep shade on the streambed; and

b.

The buffer will not apply to the following land-disturbing activities, provided that they occur at an angle, as measured from the point of crossing, within 25 degrees of perpendicular to the stream; cause a width of disturbance of not more than 50 feet within the buffer; and adequate erosion control measures are incorporated into the project plans and specifications and are implemented: (i) stream crossings for water lines; or (ii) stream crossings for sewer lines;

16.

There is established a 50-foot buffer as measured horizontally from the point where vegetation has been wrested by normal stream flow or wave action, along the banks of any state waters classified as "trout streams" pursuant to Article 2 of Chapter 5 of Title 12, the "Georgia Water Quality Control Act," except where a roadway drainage structure must be constructed; provided, however, that small springs and streams classified as trout streams which discharge an average annual flow of 25 gallons per minute or less must have a 25-foot buffer or they may be piped, at the discretion of the landowner, pursuant to the terms of a rule providing for a general variance promulgated by the Board of Natural Resources, so long as any such pipe stops short of the downstream landowner's property and the landowner complies with the buffer requirement for any adjacent trout streams. The Director, EPD may grant a variance from such buffer to allow land-disturbing activity, provided that adequate erosion control measures are incorporated in the project plans and specifications and are implemented. The following requirements apply to such buffer:

a.

No land-disturbing activities will be conducted within a buffer and a buffer must remain in its natural, undisturbed, state of vegetation until all land-disturbing activities on the construction site are completed. Once the final stabilization of the site is achieved, a buffer may be thinned or trimmed of vegetation as long as a protective vegetative cover remains to protect water quality and aquatic habitat and a natural canopy is left in sufficient quantity to keep shade on the streambed; provided, however, that any person constructing a single unit residence, when such residence is constructed by or under contract with the owner for his or her own occupancy, may thin or trim vegetation in a buffer at any time as long as protective vegetative cover remains to protect water quality and aquatic habitat and a natural canopy is left in sufficient quantity to keep shade on the streambed; and

b.

The buffer will not apply to the following land-disturbing activities, provided that they occur at an angle, as measured from the point of crossing, within 25 degrees of perpendicular to the stream; cause a width of disturbance of not more than 50 feet within the buffer; and adequate erosion control measures are incorporated into the project plans and specifications and are implemented: (i) stream crossings for water lines; or (ii) stream crossings for sewer lines.

17.

Nothing contained in O.C.G.A. § 12-7-1 et seq. will prevent any local issuing authority from adopting rules and regulations, ordinances, or resolutions which contain stream buffer requirements that exceed the minimum requirements in Sec. 9.7.3 B. and Sec. 9.7.3 C. of this Division.

18.

The fact that land-disturbing activity for which a permit has been issued results in injury to the property of another will neither constitute proof of nor create a presumption of a violation of the standards provided for in this Division or the terms of the permit.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.7.4. - Application/Permit Process

A.

General The property owner, developer and designated planners and engineers must design and review before submittal the general development plans. The local issuing authority will review the tract to be developed and the area surrounding it. They will consult the zoning ordinance, stormwater management ordinance, subdivision ordinance, flood damage prevention ordinance, this Division, and any other ordinances, rules, regulations or permits, which regulate the development of land within the jurisdictional boundaries of the local issuing authority. However, the owner and/or operator are the only parties who may obtain a permit.

B.

Application Requirements

1.

No person will conduct any land-disturbing activity within the jurisdictional boundaries of Sandy Springs, Georgia, without first obtaining a permit from the Department to perform such activity and providing a copy of notice of intent submitted to EPD, if applicable.

2.

The application for a permit must be submitted to the Department and must include the applicant's erosion, sedimentation and pollution control plan with supporting data, as necessary. Said plans must include, as a minimum, the data specified in Sec. 9.7.4 C. of this Division. Erosion, sedimentation and pollution control plans, together with supporting data, must demonstrate affirmatively that the land-disturbing activity proposed will be carried out in such a manner that the provisions of Sec. 9.7.3 B. and Sec. 9.7.3 C. of this Division will be met. Applications for a permit will not be accepted unless accompanied by 3 copies of the applicant's erosion, sedimentation and pollution control plans. All applications must contain a certification stating that the plan preparer or the designee thereof visited the site prior to creation of the plan in accordance with EPD Rule 391-3-7-10.

3.

In addition to the local permitting fees, fees will also be assessed pursuant to paragraph O.C.G.A. § 12-5-23(5)(a), provided that such fees will not exceed $80.00 per acre of land-disturbing activity, and these fees will be calculated and paid by the primary permittee as defined in the State general permit for each acre of land-disturbing activity included in the planned development or each phase of development. All applicable fees must be paid prior to issuance of the land disturbance permit. In a jurisdiction that is certified pursuant to O.C.G.A. § 12-7-8(a), half of such fees levied will be submitted to the division; except that any and all fees due from an entity which is required to give notice pursuant to O.C.G.A. § 12-7-17(9) or (10) must be submitted in full to the division, regardless of the existence of a local issuing authority in the jurisdiction.

4.

Upon receipt of an application and plan for a permit, the City will review and approve or disapprove concerning the adequacy of the erosion, sedimentation and pollution control plan. The City will approve or disapprove a plan within 35 days of receipt. Failure of the City to act within 35 days will be considered an approval of the pending plan.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.7.5. - Inspection and Enforcement

A.

The Director will periodically inspect the sites of land-disturbing activities for which permits have been issued to determine if the activities are being conducted in accordance with the plan and if the measures required in the plan are effective in controlling erosion and sedimentation. Also, the local issuing authority will regulate primary, secondary and tertiary permittees as such terms are defined in the State general permit. Primary permittees will be responsible for installation and maintenance of best management practices where the primary permittee is conducting land-disturbing activities. Secondary permittees will be responsible for installation and maintenance of best management practices where the secondary permittee is conducting land-disturbing activities. Tertiary permittees will be responsible for installation and maintenance where the tertiary permittee is conducting land-disturbing activities. If, through inspection, it is deemed that a person engaged in land-disturbing activities as defined herein has failed to comply with the approved plan, with permit conditions, or with the provisions of this Division, a written notice to comply will be served upon that person. The notice will set forth the measures necessary to achieve compliance and will state the time within which such measures must be completed. If the person engaged in the land-disturbing activity fails to comply within the time specified, he will be deemed in violation of this Division.

B.

The local issuing authority must amend its ordinances to the extent appropriate within 12 months of any amendments to the Erosion and Sedimentation Act of 1975.

C.

The Director will have the power to conduct such investigations as it may reasonably deem necessary to carry out duties as prescribed in this Division, and for this purpose to enter at reasonable times upon any property, public or private, for the purpose of investigation and inspecting the sites of land-disturbing activities.

D.

No person will refuse entry or access to any authorized representative or agent of the local issuing authority, the commission, the district, or division who requests entry for the purposes of inspection, and who presents appropriate credentials, nor will any person obstruct, hamper or interfere with any such representative while in the process of carrying out his official duties.

E.

The district or the commission or both will semi-annually review the actions of counties and municipalities which have been certified as local issuing authorities pursuant to O.C.G.A. § 12-7-8(a). The district or the commission or both may provide technical assistance to any county or municipality for the purpose of improving the effectiveness of the county's or municipality's erosion, sedimentation and pollution control program. The district or the commission will notify the division and request investigation by the division if any deficient or ineffective local program is found.

F.

The division may periodically review the actions of counties and municipalities which have been certified as local issuing authorities pursuant to O.C.G.A. § 12-7-8(a). Such review may include, but will not be limited to, review of the administration and enforcement of a governing authority's ordinance and review of conformance with an agreement, if any, between the district and the governing authority. If such review indicates that the governing authority of any county or municipality certified pursuant to O.C.G.A. § 12-7-8(a) has not administered or enforced its ordinances or has not conducted the program in accordance with any agreement entered into pursuant to O.C.G.A. § 12-7-7(e), the division will notify the governing authority of the county or municipality in writing. The governing authority of any county or municipality so notified will have 90 days within which to take the necessary corrective action to retain certification as a local issuing authority. If the county or municipality does not take necessary corrective action within 90 days after notification by the division, the division will revoke the certification of the county or municipality as a local issuing authority.

(Ord. No. 2023-12-24, § I(Att. A), 12-5-2023)

Sec. 9.7.6. - Penalties and Incentives

A.

Failure to Obtain a Permit for Land-Disturbing Activity If any person commences any land-disturbing activity requiring a land-disturbing permit as prescribed in this Division without first obtaining said permit, the person will be subject to revocation of the work permit or other authorization for the conduct of a business and associated work activities within the jurisdictional boundaries of the local issuing authority.

B.

Stop-Work Orders

1.

For the first violation of the provisions of this Division, the Director, EPD or the local issuing authority will provide official notice to the violator. The violator will have 48 hours to correct the violation. If the violation is not corrected within 48 hours, the Director, EPD or the local issuing authority will issue a stop-work order requiring that land-disturbing activities be stopped until necessary corrective action or mitigation has occurred. In cases where there is danger of damage to state waters, stormwater systems or adjacent property a stop work order may be issued and the violator will correct the violation immediately.

2.

All stop-work orders will be effective immediately upon issuance and will be in effect until the necessary corrective action or mitigation has occurred.

3.

When a violation in the form of taking action without a permit, failure to maintain a stream buffer, failure to follow the approved plan, failure to maintain required BMPs or significant amounts of sediment, as determined by the local issuing authority or by the Director, EPD or his or her designee, have been or are being discharged into state waters, offsite or streets and where best management practices have not been properly designed, installed, and maintained, a stop-work order will be issued and citation may be issued, by the local issuing authority or by the Director, EPD or his or her designee. All such stop-work orders will be effective immediately upon issuance and will be in effect until the necessary corrective action or mitigation has occurred. Such stop-work orders will apply to all land-disturbing activity on the site with the exception of the installation and maintenance of temporary or permanent erosion and sediment controls.

C.

Bond Forfeiture If, through inspection, it is determined that a person engaged in land-disturbing activities has failed to comply with the approved plan, a written notice to comply will be served upon that person. The notice will set forth the measures necessary to achieve compliance with the plan and will state the time within which such measures must be completed. If the person engaged in the land-disturbing activity fails to comply within the time specified, he will be deemed in violation of this Division and, in addition to other penalties, will be deemed to have forfeited his performance bond, if required to post 1 under the provisions of Sec. 9.7.4 B. The local issuing authority may call the bond or any part thereof to be forfeited and may use the proceeds to hire a contractor to stabilize the site of the land-disturbing activity and bring it into compliance.

D.

Monetary Penalties Any person who violates any provisions of this Division, or any permit condition or limitation established pursuant to this Division, or who negligently or intentionally fails or refuses to comply with any final or emergency order of the Director may be cited for the violation of this Division. Any person who violates any provisions of this Division, or any permit condition or limitation established pursuant to this Division, or who negligently or intentionally fails or refuses to comply with any final or emergency order of the Director issued as provided in this Division will be liable for a civil penalty not to exceed $2,500.00 per day, except that the penalty for violations associated with stand alone residential development will be pursuant to Sec. 1-10 of the City Code. For the purpose of enforcing the provisions of this Division, notwithstanding any provisions in any City Charter to the contrary, municipal courts will be authorized to impose penalty not to exceed $2,500.00 for each violation, except that the penalty for violations associated with stand alone residential development will be pursuant to Sec. 1-10 of the City Code for each violation. Notwithstanding any limitation of law as to penalties which can be assessed for violations of county ordinances, any magistrate court or any other court of competent jurisdiction trying cases brought as violations of this Division under county ordinances approved under this Division will be authorized to impose penalties for such violations not to exceed $2,500.00 for each violation, except that the penalty for violations associated with stand alone residential development will be pursuant to Sec. 1-10 of the City Code for each violation. Each day during which violation or failure or refusal to comply continues will be a separate violation.

Sec. 9.7.7. - Education and Certification

A.

Persons involved in land development design, review, permitting, construction, monitoring, or inspection or any land-disturbing activity must meet the education and training certification requirements, dependent on their level of involvement with the process, as developed by the commission in consultation with the division and the stakeholder advisory board created pursuant to O.C.G.A. § 12-7-20.

B.

For each site on which land-disturbing activity occurs, each entity or person acting as either a primary, secondary, or tertiary permittee, as defined in the State general permit, must have as a minimum 1 person who is in responsible charge of erosion and sedimentation control activities on behalf of said entity or person and meets the applicable education or training certification requirements developed by the commission present on site whenever land-disturbing activities are conducted on that site. A project site will herein be defined as any land-disturbance site or multiple sites within a larger common plan of development or sale permitted by an owner or operator for compliance with the State general permit.

C.

Persons or entities involved in projects not requiring a state general permit but otherwise requiring certified personnel on site may contract with certified persons to meet the requirements of this Division.

D.

If a state general permittee who has operational control of land-disturbing activities for a site has met the certification requirements of O.C.G.A. § 12-7-19(b)(1), then any person or entity involved in land-disturbing activity at that site and operating in a subcontractor capacity for such permittee must meet those educational requirements specified in O.C.G.A. § 12-7-19(b)(4) and will not be required to meet any educational requirements that exceed those specified in said subsection.
