McKinley, Acting City Manager Julian Perez, Planning Directs _� February 6, 2007 ITEM No. , Subject: AN ORDINANCE OF THE MAYOR AND CITY COMMISSION OF THE CITY OF SOUTH MIAMI, FLORIDA, RELATING TO DRAINAGE; AMENDING SECTION 20 -4.7 OF THE CITY'S LAND DEVELOPMENT CODE IN ORDER TO CORRECT THE TITLE TO REFLECT "MINIMUM STANDARDS" FOR ALL CONSTRUCTION AND NOT JUST IDENTIFYING MINIMUM HOUSING STANDARDS; MODIFYING SUBSECTION (C) IN ORDER TO SPECIFICALLY REQUIRE ALL PROPERTIES TO RETAIN STORMWATER DRAINAGE ON SITE SO AS TO PREVENT DEVELOPMENT THAT WOULD RESULT IN CONTRIBUTING TO OR CAUSING RECURRENT PONDING ON ADJOINING PROPERTIES OR PUBLIC RIGHTS -OF -WAY; AND ELIMINATING SUBSECTION (J) ENTITLED "CERTIFICATE OF OCCUPANCY RELATING TO REHABILITATION AREAS AS NO SUCH CERTIFICATE IS USED IN THE CITY, AND AS REHABILITATION AREA IS NOT DEFINED; PROVIDING FOR SEVERABILITY, ORDINANCES IN CONFLICT, AND AN EFFECTIVE DATE. Request The attached proposed ordinance amending the City's Land Development Code was prepared by the City Attorney's office. The proposed ordinance strengthens existing Section 20 -4.7 of the Land Development Code which does provide that ponding of stormwater must be eliminated through proper filling, elevating, drainage, or grading of the site. The new additional wording provides that the ponding or run -off into a public street is prohibited and that the stormwater elimination technique must be maintained by the property owner. The draft legislation also provides the City with the power to deny a certificate of occupancy or certificate of use until such time as proof is provided that the development will refrain stormwater on site or that adequate drainage is provided so as to prevent the development from contributing or causing recurrent ponding to adjoining properties or public rights -of -way. The LDC ordinance is a companion to an ordinance adopted by the City Commission at its January 23, 2007. That ordinance, Ordinance No. 02 -07 -1903, amended City Code Section 10A -45 by adding specific stormwater drainage data, plans and professional engineering reports which must be submitted with a building permit application. The draft LDC ordinance also removes Section J which is an out -of -date regulation pertaining to a special certificate of occupancy for properties in rehabilitation areas. These areas do not exist under current law. Planning Board Action The Planning Board at its January 16, 2007 meeting adopted a motion by a vote of 4 ayes 2 nays (Ms. Yates, Ms. Beckman) recommending denial of the proposed ordinance. Several Planning Board members felt that the stormwater runoff submittal requirements extended too far by including renovations, additions and remodeling. (2) Recommendation: It is recommended that the draft ordinance amending LDC Section 20 -4.7 be approved with the following adjustments: (1) remove the word "remodeling" (p.2 line 30); (2) remove the word "additions" (p.2, line 30) and insert "any significant addition that results in changes to the elevation of the site that would result in runoff to adjacent properties or the right -of- way. "; (3) change the date of January 31, 2007 (p.2 line 30) to the date of the effectiveness of the ordinance.

Planning Board Applications/ Public ]Hearing PB -07 -001 Applicant: City of South Miami AN ORDINANCE OF THE MAYOR AND CITY COMMISSION OF THE CITY OF SOUTH MIAMI, FLORIDA, RELATING TO DRAINAGE; AMENDING SECTION 20 -4.7 OF THE CITY'S LAND DEVELOPMENT CODE IN ORDER TO CORRECT THE TITLE TO REFLECT "MINIMUM STANDARDS" FOR ALL CONSTRUCTION AND NOT JUST IDENTIFYING MINIMUM HOUSING STANDARDS; MODIFYING SUBSECTION (C) IN ORDER TO SPECIFICALLY REQUIRE ALL PROPERTIES TO RETAIN STORMWATER DRAINAGE ON SITE SO AS TO PREVENT DEVELOPMENT THAT WOULD RESULT IN CONTRIBUTING TO OR CAUSING RECURRENT PONDING ON ADJOINING PROPERTIES OR PUBLIC RIGHTS -OF -WAY; AND ELIMINATING SUBSECTION (J) ENTITLED "CERTIFICATE OF OCCUPANCY RELATING TO Planning Board Meeting January 16, 20072 2 REHABILITATION AREAS AS NO SUCH CERTIFICATE IS USED IN THE CITY, AND AS REHABILITATION AREA IS NOT DEFINED; PROVIDING FOR SEVERABILITY, ORDINANCES IN CONFLICT, AND AN EFFECTIVE DATE. Action: Mr. Morton read the Ordinance into the record. City Attorney Eve Boutsis provided a brief background summary of the proposed ordinance. She explained that the proposed ordinance amending the City's Land Development Code (LDC) was prepared by the City's Attorney's office. The intent of the proposed ordinance is to strengthen the City's ability to regulate stormwater runoff for all properties . The previous building code, the South Florida Building Code contained standards regulating stormwater drainage. The new state -wide code, the Florida Building Code does not provide standards for controlling runoff of stormwater and the resulting ponding impact on adjoining properties and in streets. Ms. Boutsis explained that the title of LDC Section 20 -4.7 is first being changed to Minimum Standards, eliminating the word "residential ", because this section is applicable to all properties. Ms. Boutsis explained that the proposed ordinance strengthens existing Section 20 -4.7 by requiring that ponding of stormwater must be eliminated through proper filling, elevating, drainage, or grading of the site. The new additional wording provides that the ponding or run -off into a public street is prohibited and that the stormwater elimination technique must be maintained by the property owner. The draft legislation also provides the City with the power to deny a certificate of occupancy or certificate of use until such time as proof is provided that the development will retain stormwater on site or that adequate drainage is provided so as to prevent the development from contributing or causing recurrent ponding to adjoining property(ies) or public rights -of -way. Ms. Boutsis also advised the ordinance also includes a technical change to Section J which is an out -of -date regulation requireing a special certificate of occupancy for properties in "rehabilitation areas" a term which does not exist under State or local laws. Mr. Youkilis added that other sections of the LDC require the issuance of Certificate of Occupancy for all properties. Ms. Boutsis noted that the City Commission is in the process of considering a companion ordinance amending the City Code Section 10A -45 which addresses development permit applications (building permits). It adds a requirement that stormwater drainage and engineering data must be submitted with the application. A copy of that legislation was provided to the Board members. Recommendation: Staff recommended that the Planning Board approve the draft ordinance. At this time, the Board discussed the item. Chairman Morton inquired if there was any type of criteria in City Code Section 10A -45 which guides how extensive the stormwater data submission should be. He was concerned that small projects like remodeling or small additions would require a huge investment in engineering studies before a permit could be issued. Mr. Davis also expressed concern of the cost that will be incurred by the permit holder of smaller projects with regards to remodeling. Furthermore, Mr. Davis commented Planning Board Meeting January 16, 20073 3 that residents and people that do construction work or remodeling will be affected by this change because it will cause remodeling to become less possible in the City. Ms. Beckman indicated that she had no issue with the requirements set forth in the City Code amendment. She did address the issue of the French drain and commented that she preferred to keep the French drain within the property and not for it to be built close to the swale. Ms. Yates advised that the purpose of a swale area is to hold runoff water. City attorney Boutsis indicated that the issue of the French drain will be addressed with the Public Works department. Ms. Yates indicated she had no problem with the language used in Section 10A -45. Chairman Morton did express his concern over the additional cost that will be incurred by the applicant in order to comply 'with the stormwater regulations found in Section 10A -45. Ms. Boutsis indicated that although the City Code amendment item was not before the Board she would work with the Board and staff to develop more appropriate language. Ms. Boutsis stated she had no problem with looking into the language and addressing a more cost- effective approach for the homeowners benefit. Mr. Perez responded that the cost of these engineering and stormwater studies could be $3,000 to 4,000. Ms. Beckman stated that she did not have a problem with requiring these studies because rebuilding is very expensive and could result in runoff. Chairman Morton opened the public hearing. Speakers: NAME ADDRESS SUPPORT /OPPOSE David Tucker, Sr 6556 SW 76th Terrace Opposed Mr. Tucker urged the Board to take the time to analyze the regulations because the responsibility of the homeowner regarding all the mechanisms that ensure that the stormwater does not drain onto other people's properties or right -of -ways. He felt that the Board needed to be concerned with impervious surfaces. Bob Welch 7437 SW 64 Court Neutral Mr. Welch discussed two types of construction. He suggested to the Board that developers keep the same grade because it allows percolation of water, therefore less retention of water on site. Chairman Morton closed the public hearing Ms. Yates made a motion to amend Section 20- 4.7(C)(4) of the LDC amendment to remove the word "remodeling" and to add the new wording "not exceeding 25% of building footprint" after the word "addition ". She also suggested changing Section 20 -4.7 (J) which was titled "Certificate of Occupancy" to show the new title "Reserved." The motion was seconded by Ms. Beckman. The motion failed of passage by a vote of 3 ayes and 3 nays (Mr. Davis, Mr. Morton, Ms. Young) Planning Board Meeting January 16, 20074 4 Ms. Beckman made a motion to recommend approved of the proposed ordinance as presented. There was no second. Action. Mr. Farfan made a motion to recommend denial of the proposed ordinance as presented. The motion was seconded by Mr. Davis. The motion was adopted by a vote of 4 ayes 2 nays (Ms. Beckman, Ms. Yates)
