Comprehensive Plan and Unified Development Ordinance Amendment Outline Form (UDO /Zoning 2012 -016) 2. UDO Amendment Package 3. Memo from the Commission for the Environment (CFE) 3 Michael D. Harvey, Planner III (919) 245 -2597 Reynolds Ivins, Erosion Control (919) 245 -2586 Craig Benedict, Director (919) 245 -2575 PURPOSE: To hold a public hearing on Planning Director initiated text amendments to the Unified Development Ordinance (UDO) in regards to the submission of formal site plans for projects requiring stormwater plan approval. BACKGROUND: On April 17, 2012 the BOCC approved a UDO amendment package incorporating recent stormwater management and nutrient reduction strategies implemented by the State. This included the establishment of land disturbance thresholds for both residential and non - residential projects requiring submittal of formal, engineered, stormwater plans. Please refer to Section B.1 of Attachment 1 for additional information on these thresholds. This amendment seeks to clarify existing language within the UDO denoting when a formal site plan is required and adds language requiring formal site plan submittal in those instances where proposed land disturbance exceeds established stormwater management thresholds. Staff is also proposing to include language requiring the development of formal stormwater plans, consistent with established land disturbance thresholds, for minor and major subdivisions. Please refer to Section B.2 of Attachment 1 for additional information. Attachment 2 contains the proposed amendments with additions shown in iiii d text and proposed deletions are shown in iiii iiii iiii as well as footnotes documenting the rationale for the proposed modification. Attachment 3 contains a memorandum from the CFE, which reviewed the proposal at its January 14, 2013 regular meeting. Ordinance Review Committee (ORC) Review: The Planning Board ORC reviewed the proposed amendments at its January 9, 2013 regular meeting. The proposed text in Attachment 2 includes modifications made based on comments received at the ORC. Please refer to Section C.2 (a) of Attachment 1 for a summary of the Board member's comments. Notification Procedural Requirements: Legal ads for the public hearing were placed in a newspaper of general circulation in the County in accordance with Section 2.8.7 of the UDO. FINANCIAL IMPACT: See Section C.3 in Attachment 1. RECOMMENDATION: The Planning Director recommends the Board: 1. Receive the proposed amendments to the Unified Development Ordinance as detailed in this abstract and attachments. 2. Conduct the public hearing and accept public, BOCC, and Planning Board comment on the proposed amendments. 3. Refer the matter to the Planning Board with a request that a recommendation be returned to the BOCC in time for the May 7, 2013 BOCC regular meeting. 4. Adjourn the public hearing until May 7, 2013 in order to receive and accept the Planning Board's recommendation and any submitted written comments.

Purpose /Mission In accordance with the provisions of Section 2.8 Zoning Atlas and Unified Development Ordinance Amendments of the UDO, the Planning Director has 1 Eel initiated a text amendment to modify existing language requiring the submittal of formal stormwater plans as part of subdivision and development applications. The State recently implemented stormwater management and nutrient reduction strategies. As part of these strategies, the County recently modified existing regulations mandating the preparation and submittal of formal, engineered, stormwater management plans as part of any development project where proposed land disturbance reached the following thresholds: Watershed /River Basin Stormwater — Non- Stormwater — Residential residential Cape Fear (includes the Projects proposing over Projects proposing over Back Creek, Haw River, 21,780 square feet of 43,560 square feet of Cane Creek, Jordan Lake, disturbance are required to disturbance are required to and University Lake submit a stormwater submit a stormwater protected and critical management plan. management plan. watershed overlay districts as well as those properties within the basin not located in a watershed overlay district). Neuse (includes Flat River, Projects proposing over Projects proposing over Little River, Upper and 12,000 square feet of 21,780 square feet of Lower Eno protected and disturbance are required to disturbance are required to critical watershed overlay submit a stormwater submit a stormwater districts as well as those management plan. management plan. properties within the basin not located in a watershed overlay district). Roanoke (includes South Projects proposing over Projects proposing over Hyco Creek protected 20,000 square feet of 43,560 square feet of watershed overlay district). disturbance are required to disturbance are required to submit a stormwater submit a stormwater management plan. management plan. These changes were incorporated into the UDO on April 17, 2012. The agenda packet for this meeting can be found utilizing the following link: http://orangecountync.gov/OCCLERKS/120417.htm Currently there are conflicting requirements within the UDO detailing when a formal, professionally prepared, site plan is required. For example Section 2.4.1 requires a professionally prepared site plan for single - family developments on property located within the University Lake Protected and Critical Watershed Overlay Districts. Section 2.5.2, the section of the UDO addressing site plan application requirements, specifically exempt single - family development projects from submitting a professionally prepared site plan. 0, 7 Problems also arise in those instances where a project's proposed overall land disturbance requires submission of a formal stormwater management plan. Staff does not want there to be conflicting information provided to the public as to when a formal site plan is required nor do we want the staff of Current Planning and Erosion Control to potentially be looking at 2 different sets of plans proposing the development of a given property. This proposed amendment is designed to: 1. Require formally prepared site plans for those projects exceeding established stormwater disturbance thresholds for residential projects. Submittal of formal site plans is already required for all non - residential projects regardless of the proposed land disturbance activity. 2. Incorporate references within various locations of the UDO identifying which land development projects need to comply with these standards in an effort to eliminate confusion and provide definitive application submittal standards. 3. Add language requiring stormwater management plans for minor and major subdivisions where anticipated land disturbance activities would exceed established thresholds. Both Planning and Erosion Control staff agree potential problems can be eliminated if there is a formal stormwater management plan approved during the subdivision review and approval process. 2. Analysis As required under Section 2.8.5 of the Orange County Unified Development Ordinance, the Planning Director is required to: `cause an analysis to be made of the application and, based upon that analysis, prepare a recommendation for consideration by the Planning Board and the Board of County Commissioners'. The proposed amendment is designed to incorporate established stormwater management land disturbance thresholds into existing language within the UDO requiring formal site plan preparation and submittal by an applicant when said thresholds are exceeded. By modifying existing language we hope to eliminate unnecessary cost for the applicant, with respect to the completion of multiple site plans, and provide sufficient detail to residents, property owners, and developers on when formal site plan preparation is necessary. The amendment is also designed to provide a `central site plan' for review to ensure staff is reviewing and taking action on the same document to avoid confusion and unnecessary duplication of effort. 3. Comprehensive Plan Linkage (i.e. Principles, Goals and Objectives) This amendment is designed to provide additional references to existing 3 development standards already contained within the UDO. 4. New Statutes and Rules This amendment is designed to reference compliance with recently adopted modifications to the UDO related to stormwater management and nutrient reduction standards consistent with the following State regulations: • 15A NCAC 2B. 0277 Falls Lake Stormwater New Development Rule • 15A NCAC 2B. 0265 and Session Law 2009 -484 Jordan Lake Stormwater New Development Rules C. PROCESS 1. TIMEFRAME /MILESTONES /DEADLINES a. BOCC Authorization to Proceed November 8, 2012. The BOCC voted unanimously to authorize staff to proceed with the amendment. Board members also requested staff present the proposed amendment to the Commission for the Environment (CFE) for its input. Staff presented this item to the CFE at its January 14, 2013 regular meeting. Please refer to Attachment 3 for additional information. b. Quarterly Public Hearing February 25, 2013 c.

PUBLIC INVOLVEMENT PROGRAM Mission /Scope: Public Hearing process consistent with NC State Statutes and Orange County ordinance requirements. a. Planning Board Review: 11 E:] January 9, 2013 - Ordinance Review Committee (ORC). 01 A Planning Board member identified a punctuation error in Section 2.4.1 of the proposed amendment. An error was also identified within the site plan flow chart contained in Section 2.5.2. Staff has modified the proposal accordingly. There was also a general discussion over staff's recommendation to modify Section 2.4.1 expanding the list of Watershed Protection Overlay Districts requiring a professionally prepared site plan allowing for development. Staff agreed to solicit guidance from the BOCC at the public hearing. March 6, 2013 -April 3, 2013 (recommendation) b. Advisory Boards: Commission for the Environment (CFE) - January 14, 2013.

FISCAL IMPACT While these proposed amendments are merely designed to incorporate necessary references with respect to complying with established thresholds, and requiring the submission of formal site plans in the event a stormwater management plan is required, staff had previously identified compliance with these new State required standards will impose additional costs for development projects and require additional staff resources. Workload for Current Planning and Erosion Control staff to review and approve stormwater management plans required by the rules is expected to increase. 5 Workload for staff with respect to the inspection of stormwater management features is also expected to increase. This may necessitate an increase in fees charged to developers. As reported at the February 27, 2012 Quarterly Public Hearing, it is expected that enforcement of the new regulations will require, at a minimum, up to one additional full time employee for Erosion Control with an approximate cost of $65,000. Staff is continuing to evaluate workload and needs as the process moves forward. D. AMENDMENT IMPLICATIONS The amendments are in response to recent modifications to the UDO relating to compliance with stormwater and nutrient management requirements and staff's desire to ensure proper reference for compliance with these aforementioned new standards. As previously indicated by staff, compliance with these required standards is expected to increase the cost of development and increase staff workload. E. SPECIFIC AMENDMENT LANGUAGE Please refer to Attachment 2. Primary Staff Contact: Michael D. Harvey Planning (919) 245 -2597 mharvey @orangecountync.gov me 10 11 ATTACHMENT 2 UDO AMENDMENT PACKET NOTES: The following packet details staff's proposed modifications to existing regulations governing the submittal of professionally prepared site plans for projects requiring stormwater plan approval. These amendments are based modifications to the UDO, approved on April 17, 2012, incorporating State stormwater management and nutrient reduction standards into County regulations. The intent of the proposal is to incorporate appropriate references to these new development standards to avoid the submission of multiple site plans adding to the overall cost of a development project and creating confusion for the property owner /developer. As the number of affected pages /sections of the existing UDO are being modified with this proposal staff has divided the proposed amendments into the following color coded classifications: • Red Underlined Text: Denotes new, proposed text, that staff is suggesting be added to the UDO • Red Underlined Bold Text: Denotes new, proposed text, added to address peer or advisory board comments • Red Stfi ,ethf,.,,,.i, T-ex : Denotes existing text that staff is proposing to delete Staff has included footnotes within the amendment package to provide additional information /rationale concerning the proposed amendments to aid in your review. Only those pages of the UDO impacted by the proposed modification(s) have been included within this packet. Some text on the following pages has a large "X" through it to denote that these sections are not part of the amendments under consideration. The text is shown only because in the full UDO it is on the same page as text proposed for amendment or footnotes from previous sections `spill over' onto the included page. Text with a large "X" is not proposed for deletion. Please note that the page numbers in this amendment packet may or may not necessarily correspond to the page numbers in the adopted UDO because adding text may shift all of the text /sections downward. Users are reminded that these excerpts are part of a much larger document (the UDO) that regulates land use and development in Orange County. The full UDO is available online at: http: / /orangecountync.gov /planning /Ordinances. asp Article 2: Procedures 12 Section 2.4: Zoning Compliance Permits Amendments initiated by Orange County shall not be subject to time limitat s other than those specified by the Board of County Commissioners during th blic hearing (E) EviclenceNot presented at the public hearing may be sub ed in writing to the Planning Board for con ration prior to the Planning Board's ommendation to the Board of County Commissio s.

(B) In makin ' decision, the Board of Commissioners shall sider all relevant evidence prese d at the public hearing and any submitted written evi e that was considered e Planning Board in making its recommendation. ( The Board of Commissioners, upon receipt of a recommended Comprehe i e Plan or portion thereof from the Planning Board, shall consider such recommendations d adopt them by resolution, either unchanged or with modifications. 2.4.1 Applicability (A) As required by this Ordinance, a Zoning Compliance Permit must be issued before any new site development, building, structure, or vehicular use area may be erected, constructed or used. (B) Submittal and approval of a site plan (see Section 2.5) is required for issuance of a Zoning Compliance Permit except for: (1) Single- family detached dwellings and duplexes, and accessory structures to those residential uses t#edeveloped on property located outside of the Upper Eno Critical, Little River Protected, University Lake and Cane Creek Protected and Critical Watershed Protection Overlay Districts. In these instances a Plot Plan, as detailed within Section 2.4.3 of this Ordinance, shall be required., site Plan approval shall be thew rocirlontiol i icoc droll be FG9 tired to s Limit o Dlet plop (coo Continn 7 it 2 fnr Dlnt Dlon c r�onifinotiORS In those instances where the proposed level of land disturbance exceeds established thresholds detailed within Section 6.14.5 of the Ordinance a formal site plan, prepared in accordance with Section 2.5, shall be required for submittal and approval regardless of the proposed land use or Watershed Protection The existing wording of the UDO has created confusion in the past over when a site plan is required. We have streamlined existing language in an attempt to eliminate confusion and specifically spell out when a plot plan versus a site plan is actually required. Staff is also proposing to add language requiring formal site plans in other Watershed Protection Overlay Districts having similar characteristics to the University Lake Protected and Critical Watershed Protection Overlay Districts in order to establish greater uniformity within the Ordinance. Specifically staff is modifying the UDO to require a formal site plan in those overlay districts where a 6% impervious surface limit in enforced. There will need to be discussion on this item as there are implications to expanding the list, most notably more property owners will be required to secure a professionally prepared site plan than ever before. The BOCC may wish to revise this section in its entirety to limit submittal of site plans in those instances where formal stormwater management plans are required. Orange County, North Carolina — Unified Development Ordinance Page 2 -7 Article 2: Procedures 13 Section 2.4: Zoning Compliance Permits Overlay District designation of the subject Property .2 This site plan may contain all required elements associated with obtaining a Zoning Compliance, Erosion Control, and Stormwater permit as detailed herein,3 (2) Interior renovation or repair of an existing structure, provided the use of the lot and /or structure has not changed. (C) Issuance of a Zoning Compliance Permit is required prior to beginning the excavation for the construction, moving, alteration, or repair, except ordinary repairs, of any building or other structure, including an accessory structure. The Zoning Compliance Permit shall include a determination that plans, specifications and the intended use of the structure conforms to the provisions of this Ordinance. (D) Issuance of a Zoning Compliance Permit is required to change the type of use or type of occupancy of any building, or to expand any use on any lot on which there is a non- conforming use. The Zoning Compliance Permit shall include a determination that the proposed use conforms to the provisions of this Ordinance. Requirements and Conditions In cases where the development and /or commencement of a land use requir the issuance of a Special Use or a Conditional Use Permit, a Zoning Compli ce Permit shall be issued until the aforementioned permit has been issued by th esponsible board in ac dance with the review and approval procedures detailed rein. (B) Issuance o Special Use or Conditional Use Permit does t negate the requirement for a Zoning Comp i ce Permit. (C) Issuance of a Zoning mpliance Permit does establish a vested right to begin and complete construction or nge the use /oc pancy of a lot or building should regulations change subseque o issu e of said permit. (D) Application for Zoning Complianc it shall specify the method of disposal of trees, limbs, stumps and constructio ebris as ciated with the permitted activity. Open burning of trees, limbs, �itb ps, and /or cons t tion debris associated with the permitted activity is expressly p ited . (E) No building, str ure, or zoning lot for which a Zoning pliance Permit has been issued shal e used or occupied until the Building Inspecto as, after final inspection, issued ertificate of Occupancy indicating compliance with al e provisions of this Or " ance. (F) o building, structure, or zoning lot for which a Zoning Compliance Permi s been issued shall be used or occupied until the Orange County Health Department approved the water supply and sewage disposal systems serving that use. 2 There is an existing disconnect between permit submittal requirements for a Zoning Compliance Permit and a Stormwater management plan. Staff of Current Planning and Erosion Control could, essentially, be looking at 2 different proposals as there is not an appropriate reference to the stormwater permitting requirement in this section of the UDO. There is also a disconnect with respect to the required level of site plan detail (i.e. professionally prepared versus scaled plot plan) to obtain a land disturbing permit. Staff is proposing to add language requiring a formal site plan, completed by a land surveyor or engineer, in all instances where proposed land disturbance thresholds require the development of a formal stormwater plan. The hope here is we will avoid the duplication of submittal information and ensure all County review agencies are utilizing and reviewing the same development proposal to avoid unnecessary confusion and error. 3 The red bold text was added to address comments from the January 9, 2013 ORC meeting where members wanted some language encouraging the submittal of a single site plan complying with all zoning and erosion control / stormwater permit requirements. Orange County, North Carolina — Unified Development Ordinance Page 2 -8 Article 2: Procedures 14 Section 2.5: Site Plan Review (G) Issu Certificate of Occupancy by the Building Official or roval of a water supply and sewa sal system by the Health D ent shall in no case be construed as waiving any prov t nance.

(B) Base plot plans are available from the Planning Department and can be printed for a fee in accordance with the established fee schedule. Applicants may also use other sources of base plot plans provided the requirements of this Section are met.

The avoidance of congestion and overcrowding and the creation of conditions essential to public health, safety and the general welfare may be best accomplished through the application of design standards Orange County, North Carolina — Unified Development Ordinance Page 7 -7 Article 7: Subdivisions 17 Section 7.6: General Design Standards providing for the distribution of population and traffic, safe and coordinated street systems, approved water supply and sewage disposal systems, usable lots and conformance to plans for Orange County as recommended by the Planning Board and adopted by the Board of Commissioners. The following general requirements and principles of land subdivision shall be observed: 7.6.1 Minimum Lot Size (A) All lots shall contain the minimum lot area required by Article 3 of this Ordinance and shall comply with all applicable development standards. (B) Any lot which provides an easement for individual septic disposal for use by a separate lot shall contain an additional 20,000 square feet to accommodate the septic easement. 7.6.2 Residential Density The allowable density on a given parcel of property proposed for subdivision shall comply with the residential maximum density requirements in Section 4.2.4. 7.6.3 Land Suitabili (A) In reviewing subdivision proposals, the Planning Department and Planning Board shall consider the overall design of the subdivision with the suitability of the land for development to insure that the platting and development of the subdivision will not create a danger to the health, safety, and welfare of Orange County residents. (B) Land suitability shall be determined by an investigation of conditions including but not limited to flood prone areas, soil drainage, drainage patterns, slope, historic sites, maximum anticipated levels of land disturbance for the project and all proposed individual lots, and unique natural areas. The investigations shall be carried out by the Planning Board, the Planning Department, or other agencies or individuals having the appropriate technical expertise. (C) Special Flood Hazard Areas shall be considered during the review process. (D) Soils shall be evaluated for suitability or provisional suitability for septic tanks according to guidelines established in the Laws and Rules for Ground Absorption Sewage Disposal Systems, incorporated herein by reference.

(4) Roads, driveways and utilities shall be protected from damage caused by improper stormwater management. (5) Mechanical devices, drainage easements, natural buffers, large lots, and /or other technical means may be used to achieve these drainage objectives. Natural drainageways are a preferred means of stormwater run -off removal. The characteristics (including capacity) of natural drainageways shall be protected. (6) Runoff levels from the 25 -year storm after the site is developed shall not be greater than the rate of runoff on the same site in its natural state. Orange County, North Carolina — Unified Development Ordinance Page 7 -8 Article 7: Subdivisions 18 Section 7.7: Lots (7) In cases where anticipated land disturbance for the subdivision and the proposed lots will cumulatively exceed established thresholds denoted within Section 6.14.5 of this Ordinance, a formal stormwater management plan shall be required as part of the application submittal. (F) Resource Protection (1) Applications for subdivision shall be evaluated by the Planning Depart nt and Planning Board for potential impairment of habitat of rare and endan red species or unique natural areas. (2) A strategy shall be developed to protect resources listed by the orth Carolina Heritage Program, or identified in "An Inventory of Sites of Cu ral, Historic, Recreational, Biological, and Geological Significance in the nincorporated \ Portions of Orange County" or "Inventory of the Natural A as and Wildlife Habitats of Orange County, North Carolina ". (a) The strategy shall provide protection of iden Y ied natural and cultural resources from impacts which could result om development of the subdivision, and shall include one or mo of the following: (i) Dedication of conservation a ements, Restrictive covenants pro iting clearing or disturbance of the resource areas, (iii) Dedication of resour areas to Orange County, (iv) ustering of lots minimize land disturbance and preserve the sp ial feature of the property, (v) Other estri ons or development options which provide an adequa vel of protection. (3) The Planning Departm t s II review available documentation of the particular site and determine if e prop ed strategy adequately protects the identified resources. (4) Maps, studies, d reports which a relevant to this section shall be maintained by the Planni Department. 7.7.1 Generall All lots shall confoi;0 to all of the requirements of this Ordinance r the zoning district and any overlay district in hich they are located. 7.7.2 Shaoe and (A) T e shape and orientation of lots shall be appropriate to the locat\prov�ide sion nd the development intended. (B) Interior lot lines extending from a street should be approximately radial to the street right of way line. C) Lot lines shall be located to permit efficient installation and maintenes on utility easements, to maximize buildable area, and, where applica suitable area for septic systems. 6 Staff would prefer c omprehensive stormwater management plans rather than multiple plans, multiple systems, on individual lots that all have to be inspected by Erosion Control on a semi annual basis and maintained by individual property owners. Through this process staff is hoping to encourage neighborhood wide stormwater management plans to avoid unnecessary development and maintenance costs on individual property owners and encourage a comprehensive approach to stormwater and nutrient management. Orange County, North Carolina — Unified Development Ordinance Page 7 -9 Attachment 3 ORANGE COUNTY tc� I Department of Environment, Agriculture, Parks & Recreation MEMORANDUM TO: Michael Harvey, Current Planning Supervisor FROM: Rich Shaw, DEAPR Land Conservation Manager DATE: January 16, 2013 SUBJECT: CFE Consideration of Proposed UDO Amendment Requiring Stormwater Manaaement Plan with the Site Plan Application Thank you for attending the January 14 meeting of the Commission for the Environment (CFE) to explain proposed changes to the Unified Development Ordinance (UDO) that would require submittal of formal site plans and stormwater management plans for residential and non - residential development projects. CFE members were interested to learn more about the County's existing regulations that were recently modified (April 2012) to address the State - mandated stormwater management and nutrient reduction strategies. They now understand the County requires the preparation and submittal of engineered stormwater management plans as part of development projects where land disturbance reaches certain thresholds. You explained the proposed amendments would require that the stormwater management plan be submitted along with the formal site plan, thereby improving the coordinated review of the project by departments and avoiding some of the time and expense of having to modify the site plan at a later date. The CFE expressed its appreciation for your briefing and your responses to questions. There were no adverse reactions or issues raised by CFE members. Again, thank you for efforts to involve the CFE in the consideration of this proposed amendment to the UDO. cc: David Neal, CFE Chair Orange County Department of Environment, Agriculture, Parks & Recreation PO Box 8181, Hillsborough, NC 27278 Phone: (919) 245 -2510 Fax: (919) 644 -3351 19 20 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 � 1111111111111111111111111111111 1 1 1111 111111������� � °111111111111111111111111111 11111111 1 1 1 1 1 1 1 1 I 1 1 I 1 1 I 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1111 1 I 1 � 1 1 1 1 11 1 1111 1 11 1 1 1 II 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1� 11 1 1 I � 1111111111111111111111 1 1 1 1 1 1 1 11111111111 ° ° °�1 lllllll 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 III 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 11111111111111 11 ������ � 11111111111111111111111 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 � 1 1 1 1 1 1 1 III 111111111111111111111111111 Illllul 111111111 1 ����il111111111111111111111111111111111111111 IIIIIII X1111111111 11111111111111111111111111111111111111 1111111111111111111111111111111111111 1 1 1 1 I 1I 11 I I III 1 1 1 I 1 I Illllllllllllllllllllllllllllllllllllllll�u��„ IIIIIIIIIII u��� 111 11111 11111111 11111111111111111111111111111111111111111 Illllu IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII 1�i„ III i��� 1 �IIIIIII IIIIIIIIIII I II I 1 I 1 1 II 1 lu I I I I I I II I I 1 1 1 II 1 u i i I I I I I I �ulll III II i jjji I I I I I I I I 1 II 1 u 111111 IIIIII III u�� II IIIIII i I I I II i �IIIIIIIII1111111111111I 1 1 1 1 1 1 1 1 1 1 1 1 I II II lu iiulll�� IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII�uII�� 1111111 II II I I I I I I I I I I I i I I I I I I I I I I I I I I li i IIl (IIIIIIIIIII I11111111111111111111111111111111 IIIIII IIIIIIII�uII� IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII �i,II, Illllli
