(b)
Compliance with code. The permit shall be a license to proceed with the work and shall not be construed as authority to violate, cancel or set aside any of the provisions of this chapter except as specifically stipulated by legally granted waivers or modifications as described in the application. The issuance of a permit shall not prevent the department from thereafter requiring a correction of errors in plans or in construction or of violations of this chapter and all other applicable laws or ordinances specifically referring thereto. Certification by a certified engineer that the plans and specifications are in compliance with this chapter shall be accepted by the director as prima facie evidence that all the requirements of this chapter have been met unless he discovers otherwise.
(c)
Compliance with permit. All work must conform to the approved application and plans for which the permit has been issued and any approved amendments to the permit.
(d)
Compliance with plot plan. All new work shall be located strictly in accordance with the approved plot plan.
(e)
Change in plot plan. No lot or plot shall be changed, increased or diminished in area from that shown on the official plot plan, unless a revised diagram showing such changes accompanied by the necessary affidavit of owner or applicant shall have been filed and approved; except, that such revised plot plan will not be required if the change is caused by reason of an official street opening, street widening or other public improvement.
(f)
Compliance with plumbing and gas fitting regulations. Permits for the erection, enlargement or alteration of buildings will not be issued until evidence has been presented that the plans of the proposed building comply with all applicable regulations relating to water supply, sewerage, drainage, plumbing and gas fitting.
(g)
Compliance with zoning regulations. The building or structure must comply with all applicable zoning regulations, including all conditions and development standards attached to a site plan approved under Chapter 59. The issuance of a permit by the Department for the building or structure does not affect an otherwise applicable zoning regulation.
(h)
Compliance with location certificate. Before any first floor construction of a building or structure is placed upon the foundation walls thereof, the owner of such building or structure shall provide the department with two (2) copies of a location plat, certified by a land surveyor entitled by law to practice property line surveying in the state; except, that a professional engineer entitled by law to practice in this state may provide such certification only where property lines and corners are already existing and determined on the ground. This plat shall be drawn accurately to an appropriate scale and shall show the actual location of the building or structure walls with respect to property lines and existing buildings or structures on the same lot, parcel or tract.
(i)
Compliance with excavation, grading and sediment control regulations.
(1)
Unless the construction is exempted by Chapter 19, an applicant for a building permit must obtain a sediment control permit before the building permit is issued.
(2)
If a sediment control permit is suspended or revoked, the building permit for construction within the area subject to the sediment control permit may be suspended or revoked.
(3)
All work shall conform to plans approved and/or permits issued in accordance with Chapter 19 of this Code.
(j)
Compliance with performance bond for construction of streets before issuance of permit. As used in this subsection, the phrase “such streets” means streets abutting the building site and those extensions of streets necessary to meet the minimum requirements of Chapter 49.
(1)
A permit must not be issued for the erection of any building or structure unless the applicant delivers to the County a performance bond for the construction of streets in all rights-of-way abutting the property on which the building or structure will be erected and those extensions of streets necessary to meet the minimum requirements of Chapter 49. However, a performance bond for the construction of streets is not required when:
(A)
all streets are paved with a hard surface and have been accepted for maintenance or are being maintained by the County; or
(B)
the County Council authorized construction of each street on a front foot assessment basis.
(2)
The performance bond to be delivered shall be that bond required by Section 49-40 of this Code, and such bond shall be in an amount to cover the entire cost of construction of such streets.
(3)
If the applicant owns, or is obligated by contract to develop, all or substantially all of the property abutting the streets, a bond in an amount to cover the cost of grading of the streets is sufficient to obtain a building permit. When the applicant does not own, and is not obligated by contract to develop, all or substantially all of the property abutting the streets, the applicant may demand that the Director of Transportation present to the County Council the applicant's proposal to construct the streets on a front-foot-assessment basis. If the County Council refuses to authorize the construction of the streets on a front-foot- assessment basis, the Department must not require the applicant to post a performance bond.
(4)
Whenever the applicant must post a performance bond to cover the entire cost of construction, the applicant simultaneously must apply to the Department of Permitting Services for a permit to construct the streets. If the bond covers only grading, the applicant simultaneously must apply for a permit to grade the streets.
(5)
If the construction or grading guaranteed by such bond is not begun and completed within a period of one (1) year after the delivery of such bond, the County may proceed to cause such work to be done, in accordance with the provisions of Chapter 49 of this Code and hold the principal or surety on such bond or both liable for the cost thereof.

Location of underground utilities. On all work calling for excavation exceeding twelve (12) inches in depth, the applicant shall provide evidence of the location of all utility lines within the area of the proposed excavation.
(l)
Compliance with stop work orders. The issuance of a permit shall be expressly conditioned upon the applicant's prompt compliance with all stop work orders issued by the Director.
(m)
County line. Every building or other structure for which a permit is issued must be located completely in the County.
(n)
Tree protection. If any clearing, construction, or development allowed by any permit issued under this Chapter would result in the trimming, cutting, removal, or injury of any roadside tree (as defined in Section 49-35) or any tree located in a State right-of-way in the County, the Director must not issue that permit until:
(1)
the applicant obtains a roadside tree care permit as necessary from the State Department of Natural Resources; and
(2)
the applicant has submitted, in connection with the permit applied for under this Chapter, and the Director has approved, a site-specific tree protection plan that meets the requirements of Section 49-36A(d).
The Department must approve or reject each proposed plan within 30 days after receiving it. If the Department does not act on a proposed plan within 30 days, the plan is approved by default. The Department may require further information after a proposed plan is submitted, and may extend this deadline once for an additional 15 days to receive any needed information. The Department also may extend this deadline at the request of the applicant.
(o)
Regulations. The Director may recommend, and the Executive may adopt, regulations under Method (2) to specify standards and practices needed to protect and maintain roadside trees, including construction practices needed to prevent or minimize damage to roadside trees, under subsection (n) These regulations must be at least as stringent as applicable state roadside tree care standards and requirements.

Sec. 8-29B. Control of water runoff on small lots.LinkCopy Citation
(a)
The Director must not issue a building permit for any detached one- or two-family residential building located on a recorded lot smaller than 15,000 square feet, or a permit for any addition to such a residential building that would increase the building lot coverage by more than 400 square feet, unless the plans provide for safe conveyance or control of any increased water runoff, resulting from additional impervious area or any other topographic alteration, that would drain onto any adjacent or nearly private property.
(b)
In this Section, approved drainage system means any method of safe conveyance from the property or storage on the property of on-site water runoff at the design rate specified in subsection (c), using one or more of the following methods or devices or any other method or device approved by the Director that would provide equivalent or greater protection of adjacent and nearby properties:
(1)
on-site absorption or drainage device, such as rain barrel, cistern with slow release or controlled pump discharge, underground percolation and storage system, rain garden, rooftop garden or detention device, bioretention filter, or vegetation buffer;
(2)
existing or new drainage facility, such as drainage interceptor, inlet, trench, permeable paved area, or similar feature;
(3)
drainage line, inlet or pipe, or other engineered feature such as a swale or ditch; or
(4)
natural topography or buffer area that successfully absorbs water drainage.
(c)
Each approved drainage system must be designed to convey or control at least 1.5 inches of rainfall during a 24-hour period.
(d)
After the approved drainage system is installed, the permittee must certify to the Director that the system:
(1)
has been installed as provided in the plans approved by the Director; and
(2)
will convey or control the water runoff specified in subsection (c) without impacting adjacent or nearby private properties.
(e)
The permittee and the permittee’s successors in interest must preserve and maintain each approved drainage system to the extent necessary to provide the same level of protection for adjacent and nearby properties. The permittee and the permittee’s successors in interest must obtain the Director’s approval before materially modifying any element of an approved drainage system. The Director may require a permittee to record an easement in the County land records for any approved drainage system to assure the continued preservation and maintenance of that system.
