Agenda 2. Presentation: Discussion on Post Construction Controls Ordinance Environment Committee Meeting Summary for October 23, 2007 Page 2 DISCUSSION HIGHLIGHTS Committee Discussion: Council member Foxx welcomed everyone to the meeting and asked Julie Burch to give an update on today’s discussion. Ms. Burch advised those in attendance that there would be a departure from the printed agenda, because the stakeholders group has reached a new consensus. They have completed their work ahead of schedule. Staff is prepared to discuss the material in the consensus document and have attached several papers to the agenda for review as well. Ms. Burch then turned the meeting over to Daryl Hammock. I. Post Construction Controls Ordinance Daryl Hammock began his presentation [copy attached] and noted that Jeff Hieronymus and Stewart Edwards would also be making part of the presentation today. [Stakeholder Process Update / Slide] Mumford: Is the consensus coming back in a letter format or something more definitive? We’ve gone through something like this before. Hammock: We can. We thought we would have each stakeholder at the Council meeting on November 12 stand up to show their support. We thought that in-person attestation would be good. Mumford: But, we have consensus now on consensus? Hammock: Yes. Information Attachments – Cost Analysis Results and Review One thing to note is in the example where the parking spaces were removed; we should not assume going forward that every development can lose parking spaces. We can’t come up with a perfect example to explain cost. We can provide a bulleted list that explains the differences. Information Attachments – Gap Analysis between Current Impairment and Water Quality Standards The environmental gap was determined to be $1 billion. This is due to continued erosion problems at buildout without detention measures. The number could be higher. Environment Committee Meeting Summary for October 23, 2007 Page 3 Information Attachments – Summary of Issues with Charlotte-Mecklenburg Schools One change that was made which is a benefit to schools relates to ballfields. The open space definition used to say that built upon areas excluded ballfields, it has been revised to say built upon areas include ballfields, thereby reducing the requirement for open space. You get some credit now for a ballfield. Jeff Hieronymus began his presentation on Approved Ordinance Modifications – Stakeholders Modifications. [Detention / Slide] Carter: Does this reduce the current regulations? Hieronymus: No. In the original ordinance we showed one year of volume for all developments. We have now eliminated I-1 and I-2. But, they still have to meet current regulations and the stakeholders’ recommendation. Carter: I’m sure this is percentages whichever way they go. Hieronymus: This was an easy item because industrial zones are a small percentage of the changed land use. If you compare I-1 and I-2, they probably make up 1% of the zoning changes to build out, so that is too small an impact to water quality. They still have to meet the requirement of 85% TSS removal though. [Open Space / Slide] Foxx: To confirm 25% of rights-of-way counts toward the open space requirement? Hieronymus: Yes. [Impacts to Environmental Protection and Costs / Slide] Carter: Is this protection from water volume? Hieronymus: All except industrial. Carter: But, it is the same ratio as water quality? Hieronymus: Yes. Foxx: I think it would be helpful to have a side-by-side comparison of what the Environment Committee Meeting Summary for October 23, 2007 Page 4 original ordinance said and what the stakeholders have done. Stewart Edwards began his presentation on Approved Ordinance Modifications – Staff Modifications. Foxx: I’d like to say that it was remarkable for the stakeholders to spend 30 meetings already and then spend more time to come back with consensus. This process worked really well and I appreciate everyone’s input. The real estate developers get beat up sometimes. [Modifications to Redevelopment / Slide] Carter: I am concerned about mitigation points near development and transferring to an area is not appropriate. Is there any indication about where they transfer points or can it be anywhere? Hammock: There are limits and we’d like for mitigation to be placed where it occurs. The goal is to have the mitigation in the same named watershed. But, there are challenges and sometimes there might not be opportunities to do something close and economical. We don’t want to condemn a property to implement a stormwater control. But, sometimes it is hard to find an open area in a particular watershed. Carter: If possible, I’d like to add that preferred citing be as closely defined as possible. [Six Mile Creek / Slide] Carter: I thought the eastside had the heelsplitter. Edwards: This is in the six mile creek area. Carter: But, it should be east and not southeast. Edwards: This document only pertains to the area that is shown on this map. Hammock: There are State and Federal protections for the Carolina Heelsplitter in South Carolina beyond the line that are stringent on us in the watershed. It is a protected mussel. The Yadkin watershed is different. It is further away from Charlotte. The regulations are more stringent in the area closest to the heelsplitter. The State added an additional buffer this year for this watershed alone. Carter: The heelsplitter is north as well. Environment Committee Meeting Summary for October 23, 2007 Page 5 Hammock: In Union County, on the other side of the line. It has not been assigned this level of protection. Carter: What about our contiguous ETJ? Hammock: This is in our ETJ. Carter: What about further north? Doesn’t this affect the Monroe Connector? Hammock: That’s in Union County. Carter: But, we are right on the edge. Hammock: In the draft document we sent to the State, they reviewed the buffer protection and approved what we sent. This area has additional protection. We have to do the State minimum in this area. Mumford: Could you just check on that and respond to CM Carter? Hammock: Yes. (Please see the attached Issue Paper for additional discussion of stream buffers to protect endangered species) [Discussion and Adoption Schedule / Slide] Burch: This is the schedule if you want this Council to take action. You could have the public hearing on the same night as adoption. Carter: I am ready to move ahead today. Burch: You can do that. There is an advantage to having the public hearing on November 12 and adoption the same night. Mumford: I think adoption will be easier because there is consensus. This is a big body of work though, I don’t think you can drop it at dinner and then have a vote. What is the impact of this vs. the General Development Policies – Environment? Did we reconcile the overlap and was this discussed with the stakeholders? Hammock: I am not aware of any conflicts. You’ll be discussing the GDPEnvironment today as well. They are complementary. Burgess: I think we should schedule the vote today. If we put this on November 12 and there are any glitches, we still have November 26. Environment Committee Meeting Summary for October 23, 2007 Page 6 Carter: I think the complementary language is a benefit and we should move today. Burgess: I move approval of the Post Construction Controls Ordinance. Carter: Second. Motion passes unanimously (Foxx, Mumford, Burgess, Carter, Lochman – for) Foxx: This document is extremely technical. I think it would be proactive to offer people the opportunity to meet with staff. Burch: We’ll definitely send information out early. Once the document is ready, we’ll get it to Council. Foxx: And, include language on the ordinance differences. Burch: We’ll aim to have this ready for public inspection by Friday, November 2. Foxx: The charge to the stakeholders was to come up with a list of new issues/ concerns. Since there is consensus, the development of that list may be obsolete; however there may be some interest. Some may feel that every issue was not raised, so we need to give an opportunity to have all issues included. Burch: As a side note, we’re looking at a proposed effective date of July 1, 2008, assuming this passes by the end of the November. We’ll need to have some extensive training. Foxx: Thank you and thanks to staff. This process has gone very well and Daryl Hammock and Rusty Rozzelle have maintained great attitudes! Burch: Yes, thanks to Rusty Rozzelle for facilitating this process. II. General Development Policies - Environment Council member Foxx then turned the meeting over to Garet Johnson to begin discussing the General Development Policies – Environment. Ms. Johnson reminded the Committee of the review process to date and advised that at their October 16 meeting, the Planning Committee unanimously recommended adoption. There were eight changes recommended by staff also included in the final document. There were 12 citizen comments that resulted in seven changes. Those comments are included in their entirety in the agenda package [copy attached] as well as results from an Environment Committee Meeting Summary for October 23, 2007 Page 7 online survey. Two issues for follow up from the last meeting were 1) consistency and 2) implementation. Regarding consistency, during the development of the cost analysis we also looked at consistency between the draft Urban Street Design Guidelines (USDG), Post Construction Controls Ordinance (PCCO) and the General Development Policies (GDP). In particular, we looked at four concerns expressed by the Chamber’s land use committee. 1) Streets in environmentally sensitive areas - The USDG is not one size fits all. Rather, the street designs respond to the land uses. Since the land use in environmentally sensitive areas is less intense there would not be a conflict. 2) Water Quality and Creek Crossings – the USDG provide flexibility. 3) Post Construction Controls costs – there is flexibility particularly in redevelopment in the transit station areas and distressed business districts. We can forgo some of the requirements and do some “payments in lieu”. 4) Balancing Competing Interests – we have a guiding principle that speaks to balancing competing interests. Regarding implementation, there is a brief section on “tools” in the document. In the phase 2 document, we identified the following tools: 1) area planning; 2) research, data and analysis; 3) information and education; 4) land acquisition and disposal; 5) interagency communication / cooperation; 6) rezoning and subdivision process; 7) ordinance changes; and 8) ongoing policy review and alignment. Under each tool, staff has strategies for implementation. We will be continuing discussions on specific strategies. Foxx: Item number 10 in the staff responses, by reference to the development process isn’t that at odds with State G.S. 168-371? Has staff evaluated that? You can evaluate development only to see if it is acceptable to the ordinance language, and here you are suggesting things external to the ordinance. I’m looking at an email from Ms. Knotts. Johnson: If you’re talking about the subdivision ordinance, it is the law, so we follow the ordinance. We use the term development proposals very broadly, so we are not just looking at these during the rezoning process, we are evaluating all kinds of proposals not just those that are rezoning or subdivision. We have to follow the ordinance unless we pursue changes to the ordinance, which would be a difficult process. Foxx: So, our view would be to make changes to the development proposals not Environment Committee Meeting Summary for October 23, 2007 Page 8 in the process but look at the ordinance when making suggestions? Campbell: Absolutely. I’m not certain of Ms. Knott’s concerns, but we would have to follow the ordinance. We will be looking to you all for direction to us if you think the rezoning is too narrow in scope vs. a more general look at environmental issues. But, to those concerns in the email we would be utilizing the subdivision ordinance. Foxx: Maybe on the top of page 15 you could say: “… consistent with adopted City ordinances and policies.” This would make clear that we do not have an open license to encumber the process. Without any objections, I’d like to make that change. III. Next Meeting Foxx: I’d like to have some discussion of water on November 12. This is a big issue in the community. I’d like to know what our water supply is. I’ve sent a letter to Doug Bean asking him how long we have but I think a Council discussion about where we are is worth having. Mumford: Well, I’d like to add that when it starts raining again how do we keep the changes in place? This would be a good discussion because we want to sustain our learnings. Carter: We have the 5th largest water supply, so I think that is even more relevant and I would thoroughly endorse a discussion. Mumford: One thing I hear a lot is about developments and why do we approve more development. I am not suggesting a moratorium, but we need to understand the impact. In ten years, what is the outcome? Do we have cleaner water? More water? Less trees? Do these regulations work? How much development can the environment handle? Make sure we understand and make sure we keep conservation. Carter: I would put underlines under that for emphasis. Sustainability is a priority with NLC and a crucial principle. Council member Mumford, you had this same vision for our community with housing and with transportation and I thoroughly endorse this discussion. Burch: I would like to ask to go back to the General Development Policies – Environment for action. Environment Committee Meeting Summary for October 23, 2007 Page 9 Foxx: I make a motion that we forward the General Development Policies – Environment to Council for approval with the all the changes presented including the one adding the language about consistency with ordinances and policies. Lochman: Second. Motion passes unanimously (Foxx, Mumford, Burgess, Carter, Lochman – for) Burch: So, this will go on the November 12 agenda for action. You have another Committee meeting scheduled for November 19; do you want to start the discussion on brownfields? Foxx: I’d like to discuss water on November 19. Burch: I will talk to Mr. Walton and Mr. Bean. As information, you’ll recall you gave us direction to bring the Enterprise Funds to Committee and we had previous reports from Utilities and Stormwater. It is about time for a second update, would you like that on November 19? Foxx: As a practical matter, I think Utilities would be good especially water supply. Burch: We can work with Doug Bean. Burgess: Are we meeting again? Foxx: I would like one more meeting. Burgess: Aren’t we finished? Foxx: This is just for information. Burgess: Are we back from the League meeting? Burch: Yes. This is scheduled right before the Zoning meeting. Mumford: I don’t think this would be a good time to introduce something new, since you will be getting two new members. I’m not sure there is value in initial dialogue. Foxx: It’s just information. I think getting information on water would be helpful for the full Council. Burch: There will be a report at the next meeting and we are working closely with Duke. Environment Committee Meeting Summary for October 23, 2007 Page 10 Foxx: I’d like to put the issue on the table to dialogue about water. Carter: I would like to encourage quick disclosure of the Committee appointments. Burch: Those are usually not made in the month of November since the Council is not sworn in until December. Mumford: I think we need information sharing; however, we ought to have a City Manager’s Report with Mr. Bean updating us on water. Foxx: We need some forum to ask questions in public. Burch: So, you’ll have a discussion on November 12 with the full Council, what about the Committee meeting on November 19? Foxx: I believe I’m hearing from the Committee to cancel that meeting. Burgess: It just doesn’t seem essential since we will be hearing it on the 12th. Lochman: Since we are canceling the Environment Committee meeting, we moved Economic Development and Planning to 1:30 on the 19th, can we move it to 3:30 now? Burch: I will ask Ron Kimble to poll the Committee. Foxx: I’d like to thank Council members Mumford and Lochman for their dedication and interest in this committee. Their service will be missed. Meeting adjourned. Environment Committee Tuesday, October 23, 2007 at 12:00 noon Charlotte-Mecklenburg Government Center Room CH-14 Committee Members: Anthony Foxx, Chair Patrick Mumford, Vice Chair Susan Burgess Nancy Carter Don Lochman Staff Resources: Julie Burch AGENDA I. Post Construction Controls Ordinance Staff Resource: Daryl Hammock, Engineering and Property Management The final meeting of the reconvened PCCO Stakeholders is Wednesday evening, October 17. Staff will provide an update on the process. The Stakeholders’ Supplemental report will be submitted to Council no later than November 2. Attached is additional information prepared by City staff to address questions raised at previous Committee meetings: Cost Analysis Results and Review; Gap Analysis between Current Impairment and Water Quality Standards; Summary of Issues with Charlotte-Mecklenburg Schools; and Post Construction requirements in counties surrounding Mecklenburg. Staff will be prepared to review these materials and answer questions. The draft ordinance language is also attached. The Committee is asked to provide guidance to staff about any additional information needed and the desired timetable for development of Committee recommendations to Council. II. General Development Policies – Environment Staff Resource: Garet Johnson, Planning The Council received public comments on the Environment Chapter of the GDP on October 8. Staff will respond to the comments raised, discuss consistency with other policies under consideration, discuss GDP implementation, and review the Planning Committee recommendation of October 16. The Committee is asked to develop recommendations to the Council. Additional information is attached. III. Next Meeting: TBD Distribution: Mayor/City Council Mac McCarley PCCO Stakeholders Curt Walton, City Manager Leadership Team Environmental Cabinet Brenda Freeze Environmental GDP Stakeholders POST CONSTRUCTION CONTROLS ORDINANCE Cost Analysis Results and Review City Cost Analysis • The City's cost analysis focused on the increase in construction costs and change in site layout/development density resulting from the implementation of the proposed Post Construction Controls, Urban Street Design Guidelines, and Environmental Chapter of the General Development Policies. • The construction costs include site preparation costs (water, sewer, and stormwater infrastructure, streets, and landscaping) only and do not include structure costs. • These results were presented to the Environment Committee. Cost Analysis Review • On August 22, 2007 the City solicited formal comments from stakeholders involved with Post Construction Controls, Urban Street Design Guidelines, and the Environmental Chapter of the General Development Policies, as well as other development interests within the community. • The deadline to receive comments was September 7, 2007. • No comments were received. Difference between City and developer cost magnitudes • There appears to be a large discrepancy in the results of the City’s cost analysis and cost numbers prepared by the development industry. • The City and industry agree the costs presented are accurate increases in construction costs as a result of implementing the proposed ordinance for the specific sites analyzed. • Opportunity cost, or loss of developable property, was also included in the City analysis in the form of lot reduction in the single-family tiers analysis. • However, some would argue the loss of revenue is also an issue to be considered, which includes not only spreading infrastructure costs among remaining lots, but also the revenue lost from a lot and house not being able to be sold. • The City is not familiar with the economics of site development and did not try to predict how the increase in construction costs translates into the cost of a home. The City recognizes there are probably factors to consider in this regard. Summary/Interpretation • The market adjusts to new costs as was seen with the development examples presented to the Environment Committee in water supply protection watersheds that implemented post construction controls. Entry level price points were seen in these examples reflecting real-world examples of the industry’s ability to adapt to regulations similar to the Stakeholder’s proposed Post Construction Controls • • • Ordinance. Water supply protection requirements have obviously been met in both high end and affordable housing markets. Rezoning projects, development in Huntersville, and development patterns in water supply protection areas do not appear to have been affected by the regulations. City staff and the development industry agree on the increases in construction costs on the specific case studies from the cost analysis project. The effect of the construction costs increases to the proforma, or cash flow analysis, of a development project, as well as the impact to the cost of the final product, was beyond the scope of the City's project. POST CONSTRUCTION CONTROLS ORDINANCE Gap Analysis between Current Impairment and Water Quality Standards The goal of this analysis was to identify the gap between current water quality conditions and state water quality standards. Water quality data was analyzed from four urbanized watersheds (Mallard, McAlpine, Little Sugar, and Sugar) to determine an order-ofmagnitude cost to the Storm Water Utility to remove the excess pounds of sediment to meet the water quality standard. Costs to implement volume and peak controls through Post Construction Controls regulations, which would be over and above minimum state permit requirements were calculated as well. While it is not technically possible to ensure that either option will obtain the exact same pollutant removal, the following estimates are based on best available science. An explanation of the process follows: Process to calculate the gap in water quality conditions • Calculated actual sediment load in each watershed • Calculated the sediment load anticipated when streams meet the NC DENR water quality standard • Difference between actual load and load while meeting standard is the amount of sediment that needs to be removed • Determined the average cost per pound of sediment removed for municipal BMP retrofit projects • Order-of-magnitude cost was then determined to be approximately $1 billion Costs to meet proposed peak and volume regulations • Peak and volume controls are needed to prevent sedimentation occurring due to channel erosion • The additional costs above minimum permit requirements associated with peak and volume from our single-family case study is $1360/acre • According to adopted Local Area Plans the Planning Department estimates there will be approximately 52,000 additional acres of single-family development at build-out • Using our case study as a model, the cost to the development community is on an order of magnitude of $70 million for stream channel protection in single-family development • While this is a new requirement for single-family development, commercial development is currently required to install detention measures to reduce downstream flooding impacts, which in turn helps to protect stream channels from erosion. Results • According to data in our most developed watersheds, it could cost on the order of $1 billion to meet water quality standards in streams that are currently impaired. • • If development continued under the same paradigm in the rest of the ETJ, it could cost on the order of $450 to $820 million additional dollars in BMP retrofit and stream restoration projects. The cost to the development community is on the order of $70 million to implement channel protection measures Discussion • The dollar figures presented are not meant to be absolute values but rather provide information on an order-of-magnitude of costs that can be expected • Would we rather pay $70 million up-front, or fix the stream erosion problem later for over $500 million? • The stakeholder recommended post construction ordinance represents the preferred balance between costs and environmental protection to mitigate future impacts to water quality. POST CONSTRUCTION CONTROLS ORDINANCE Summary of Issues with Charlotte-Mecklenburg Schools On September 25, 2007 City, County, and Charlotte-Mecklenburg Schools (CMS) staff met to discuss the proposed post-construction controls ordinance and potential implications of the regulations to school construction. Various issues were identified in the meeting and staff has clarified some interpretations within the ordinance which, after discussing with CMS staff, we feel will minimize the negative fiscal impact of the ordinance to school construction. At the conclusion of the meeting, and in a follow-up email, Assistant Superintendent Guy Chamberlain agreed that based on our discussions, the ordinance will have no significant adverse impact on school construction costs. A summary of the issues that were identified and discussed follows: 1. Schools staff and Mecklenburg County LUESA staff discussed the possibility of partnering, sharing of staff, and of CMS relying on LUESA for support in relation to the ordinance. Those agreements will be between LUESA and CMS. Also, there was discussion with CMS and City staff about the need for a better plan review, approval, and inspection process related to new school construction. A team of CMS and City Engineering staff are currently collaborating to work through those issues, including the effect the ordinance will have on fees. 2. We understand the concerns CMS has with regards to the proposed ordinance. We do not take the increase to construction costs and impact to development yield lightly. However, there are certain environmental goals we wish to achieve in order to sustain development in Charlotte-Mecklenburg in an eco-friendly way. 3. Federal law requires the city to implement a minimum level of stormwater controls. The costs associated with minimum federal requirements represent the majority of construction cost increases to a planned development. Storm Water Services feels the costs to implement the measures above federal requirements (to address local goals) are worth the environmental benefit. 4. Costs are expected to vary widely from site to site depending on topography, number of drainage basins, presence of buffers, watershed district, etc. 5. According to the cost analysis presented to the stakeholders, the costs that can be expected for school facilities can vary from approximately $20k/acre for a 40% impervious site to $35k/acre for a 70% impervious site. 6. Some schools have already implemented stormwater controls that meet requirements of the post construction ordinance. For instance, the recently completed Mallard Creek High School installed measures that would meet water quality and detention requirements and has undisturbed open space that meet requirements per the ordinance. 7. 30% of CMS’ jurisdiction has already implemented post construction ordinances. Schools built in water supply protection districts within the City of Charlotte ETJ are also currently required to install stormwater treatments on-site. 8. The City has worked with school officials and agreed that athletic facilities, such as football, soccer, and baseball fields will fit within the definition of Built Upon Area. By recognizing these areas as Built Upon Area, there will be a corresponding reduction in the amount of undisturbed open space required by the proposed ordinance. Therefore, most school sites will recognize minimal open space mitigation requirements if the need arises for additional land. Also, there are mitigation opportunities with regards to open space within the ordinance that schools could use by-right to offset the potential impacts to a site plan from undisturbed open space requirements. If schools used County land to mitigate offsite for open space, these costs could be reduced 10-20%. 9. With regards to review and inspection fee increases, the City does review and inspect school sites for storm water and detention design currently, as well as, best management practices in the Watershed Overlay Districts. The City fees for Land Development site plan review could increase between 15 and 20 percent as a result of added Post Construction Regulation review practices, after the first year of adoption. Currently, a typical new school construction project would require $1,160 for Detention/Drainage, $900 for Commercial Plan Review, and $815 for Tree Ordinance in Land Development User Fees (total fee = $2875). The projected increases, as a result of the proposed ordinance, would result in an additional $430 to $575 in City Land Development fees for each new school construction project.

Further, the Federal Water Pollution Control Act of 1972 (“Clean Water Act”) and federal Phase II Storm Water Rules promulgated under it, as well as rules of the North Carolina Environmental Management Commission promulgated in response to federal Phase II requirements, compel certain urbanized areas, including this jurisdiction, to adopt the minimum storm water controls such as those included in this ordinance. Therefore, the Jurisdiction establishes this set of water quality and quantity regulations to meet the requirements of state and federal law regarding control of storm water runoff and discharge. 104 (A) PURPOSE General The purpose of this ordinance 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- 1 FINAL STAKEHOLDERS’ CONSENSUS DOCUMENT.……………...............October 4, 2005 construction storm water runoff and non-point source pollution associated with new development and redevelopment. It has been determined that proper management of construction-related and post-construction storm water runoff will minimize damage to public and private property and infrastructure, safeguard the public health, safety, and general welfare, and protect water and aquatic resources. (B) Specific This ordinance seeks to meet its general purpose through the following specific objectives and means: (1) Establishing decision-making processes for development that protect the integrity of watersheds and preserve the health of water resources; (2) Minimizing changes to the pre-development hydrologic response for new development and redevelopment in their post-construction state in accordance with the requirements of this ordinance for the applicable design storm in order to reduce flooding, streambank erosion, and nonpoint and point source pollution, as well as to maintain the integrity of stream channels, aquatic habitats and healthy stream temperatures; (3) Establishing minimum post-construction storm water management standards and design criteria for the regulation and control of storm water runoff quantity and quality; (4) Establishing design and review criteria for the construction, function, and use of structural storm water control facilities that may be used to meet the minimum post-construction storm water management standards; (5) Establishing criteria for the use of better management and site design practices, such as the preservation of greenspace and other conservation areas; (6) Establishing provisions for the long-term responsibility for and maintenance of structural and nonstructural storm water best management practices (BMPs) to ensure that they continue to function as designed, are maintained appropriately, and pose minimum risk to public safety; and (7) Establishing administrative procedures for the submission, review, approval and disapproval of storm water management plans, for the inspection of approved projects, and to assure appropriate long-term maintenance. 2 FINAL STAKEHOLDERS’ CONSENSUS DOCUMENT.……………...............October 4, 2005 105 (A) APPLICABILITY AND JURISDICTION General The requirements of this article shall apply to all developments and redevelopments within the corporate limits or in the extraterritorial jurisdiction, unless one of the following exceptions applies to the development or redevelopment as of the effective date [i.e., January 1, 2006?]: (1) For residential development, preliminary subdivision plan application or in the case of minor subdivisions, construction plan for required improvements, submitted and accepted for review; (2) For nonresidential development, preliminary subdivision plan application submitted and accepted for review, provided that subdivision-wide water quality and quantity features required at the time of submittal are contained within the submittal and provided the plan is subsequently approved and all necessary easements are properly established; (3) Zoning use application submitted and accepted for review for uses that do not require a building permit; (4) Certificate of Building Code Compliance issued by the proper governmental authority; (5) Valid building permit issued pursuant to G.S. § 153A-344 or G.S. § 160A385(b)(i), so long as the permit remains valid, unexpired, and unrevoked; (6) Common law vested right established (e.g., the substantial expenditure of resources (time, labor, money) based on a good faith reliance upon having received a valid governmental approval to proceed with a project); and/or (7) A conditional zoning district (including those districts which previously were described variously as conditional district, conditional use district, parallel conditional district and parallel conditional use district) approved prior to the effective date of this article/ordinance, provided formal plan submission has been made and accepted for review either prior to 5 years from the effective date of this ordinance in the case of conditional zoning districts approved on or after November 15, 1999, or prior to 2 years from the effective date of this ordinance in the case of conditional zoning districts approved prior to November 15, 1999, and provided such plans encompass either a minimum of 22.5% of the area of the project, or any phase of a project so long as such phase is part of a project that includes project-wide water quality requirements to achieve 85% TSS removal from developed areas.

(B) General Description There are two (2) total phosphorus mitigation options available to developments greater than or equal to 60% built-upon area, including off-site mitigation and a buy-down option as described in this Section. For developments with greater than or equal to 50% and less than 60% built-upon area, off-site mitigation only is allowed provided it occurs in the same named creek system. Both off-site and buy-down mitigation will result in the construction of retrofit BMPs in the same river basin (Catawba or Yadkin) as the mitigated site. In the Western Catawba District both forms of mitigation must occur in the watershed of the same named creek system for the purpose of ensuring a balance of total phosphorus loads to lake cove areas where phosphorus is a limiting pollutant with the exception that up to 30% of the buy-down money can be spent outside the watershed. In addition, the buy-down option is available provided the jurisdiction has projects and/or property available for mitigation. There is no total phosphorus requirement in the Central Catawba District so the mitigation option is not necessary. The named creek systems referred to above include: Western Catawba: Studman Branch, Porter Branch, Neal Branch, Stowe Branch, Beaverdam Creek, Little Paw Creek, Paw Creek, Long Creek, Gar Creek, and McDowell Creek Yadkin-Southeast Catawba: Six Mile Creek, Crooked Creek, Stevens Creek, Goose Creek, Duck Creek, Long Branch, Clear Creek, Wiley Branch, Caldwell Creek, McKee Creek, Ready Creek, Fuda Creek, Back Creek, Mallard Creek, Clarke Creek, Ramah Creek, South Prong Rocky River, and West Prong Rocky River 27 FINAL STAKEHOLDERS’ CONSENSUS DOCUMENT.……………...............October 4, 2005 (C) Criteria for Off-Site Mitigation (1) The owner or designee of a proposed construction site that will include greater than or equal to 50% built upon area shall construct a BMP retrofit project designed to achieve an equivalent or greater net mass removal of total phosphorus as would be achieved by removing 70% of the total phosphorus from the proposed site. Off-site mitigation is allowed only for total phosphorus removal above 50%. On-site BMPs shall be constructed to achieve 50% removal of total phosphorus. (2) The Storm Water Administrator shall receive, review, approve, disapprove or approve with conditions an “Application for Off-Site Total Phosphorus Mitigation.” The Storm Water Administrator shall design this application to include all pertinent information.

SECTION 5: OPEN SPACE 501 PURPOSE Open Space provides for a reduction in the negative impacts from storm water runoff through non-structural means. The combination of the structural BMPs described in Section 3 with the non-structural Open Space provisions described in this Section allow the objectives of this ordinance to be fulfilled. 502 GENERAL DESCRIPTION Undisturbed Open Space is required for all development unless mitigated. The percentage of Open Space required depends on a project’s built-upon area as described below. Open Space requirements can be met in stream or lake buffers, designated common areas or on individual lots for residential development (e.g., backyards, borders, etc.). Open Space can not be designated within rights of way, utility easements, etc. where re-disturbance could occur. Grass fields can also be used to meet Open Space requirements; however, the fields must be replanted in accordance with the tree planting provisions described in Section 505 (C) below. Open Space is preferred where it will provide maximum water quality benefit (i.e. around gullies and existing drainage areas, adjacent to streams and wetlands, around structural BMPs, etc.). Cluster provisions as well as Tree and S.W.I.M. Buffer Ordinance incentives currently contained in the Jurisdiction’s ordinances will continue to apply in the area designated to meet this Open Space requirement. 31 FINAL STAKEHOLDERS’ CONSENSUS DOCUMENT.……………...............October 4, 2005 503 OPEN SPACE CRITERIA Open Space requirements apply to projects as described below.

Definition and Purpose Page 1: Replace the first sentence with the following: Charlotte is the center of one of the fastest growing regions in the country. While growth contributes to our economic vitality, it also presents challenges for achieving and maintaining a healthy environment and a sustainable regional economy. 2. Existing Conditions and Trends, page 5: Replace the data from 2003-2004 with the following excerpt from the 2006 State of the Environment Report: Unfortunately, our streams are currently degraded to the point where 73.5% of the monitored stream miles are not meeting their designated use. 3. Policy 1.a., page 7, 2nd paragraph: Change “natural resources” to “natural features” to be consistent with term used throughout the draft document. 4. Policy 3.a.,page 11: Clarify the wording as follows: Enable site designs and construction projects that: 1) facilitate the use of alternative modes of transportation; and the reduction of 2) reduce ground level temperatures; 3) minimize impacts to natural environment; 4) reduce the amount and improve the quality of stormwater run-off; and 5) use water efficiently. 5. Implementation Tools, page 14: Add another a bullet under Research, Data and Analysis that reads: As part of the City's Connectivity Program, the City will continue to develop and refine a list of roads/walkways/ pedestrian ways that could be extended to provide additional connectivity between land uses either by extension of the pavement or by providing pedestrian or bicycle connections. This is a dynamic list that will continue to be prioritized and incorporated into the capital needs assessment process to complement the new connections being provided through the development process. 6. Implementation Tools, page 14, under Information and Education: Change bullet 2 as follows: Seek opportunities to educate staff and elected/appointed officials on environmental impacts and benefits related to land development and redevelopment. 7. Implementation Tools, page 15, under Ordinances Changes: Change the 3rd bullet as follows: Review the zoning ordinance to enable “small-scale” mixed-use development and to enhance the ability to implement area plan recommendations (particularly recommendations for mixed use land uses) and to enable mixed / multi-use development on adjacent parcels in appropriate locations. 8. Throughout the document: Clarify the wording of guiding principle #4 as follows: Consider the environmental impacts of land use and development comprehensively and strive to reconcile the various environmental concerns with each other and balance them with the other land and economic development considerations. 1 Citizen Comments and Staff Responses 1. Definition and Purpose Page 1 Citizen Comment: The first sentence reads “As one of the fastest growing cities in the US, Charlotte is particularly vulnerable to the impacts that growth and development can have on the natural environment”. This was not discussed in any stakeholder meeting and no evidence was presented to prove this to be an accurate statement. The document reads correctly with the deletion of this editorial comment. Staff Response: The sentence is intended to provide context for the policies provided in the draft chapter. However, deleting the sentence does not alter the policy direction. Staff supports making a change and suggests replacing the sentence with the following sentences from the City’s adopted Environment Focus Area Plan: “Charlotte is the center of one of the fastest growing regions in the country. While growth contributes to our economic vitality, it also presents challenges for achieving and maintaining a healthy environment and a sustainable regional economy.” 2. Definition and Purpose Page 2 Citizen Comment: Last 2 sentences read “The City of Charlotte is in a position to exercise leadership in that regard for our community. The environmental policies of the GDP will help provide a framework for that leadership in terms of land use and development” I find no notes that the Council has adopted a goal of being a ‘leader’. Rather, I find that the Council has adopted a Goal that “Charlotte will safeguard the environment, balancing health, sound fiscal policy, and growth.” The GDP’s are no place for this type of puffing when they exceed the publicly adopted Goal of the elected officials Staff Response: Staff suggests that Council’s Environment Committee provide direction on whether or not it is appropriate for this sentence to remain in the document. 3. Existing Conditions and Trends Water Quality page 5 Citizen Comment: Staff used the State of the Environment Report (SOER) from 2006 for all references (see page 3) but Water Quality - where they revert to the 2003-04 report. The reference should be to the 2006 SOER report that says “since 1995 the number of creeks in poor or poor/fair condition have been cut in half” Staff Response: The statistic referenced is included on page 72 of 2006 State of the Environment Report (SOER), and is stated as being data for fiscal year 2003-2004. However, deleting this statistic does not alter the policy direction. Staff supports making a change and suggests replacing it with the following statement, also from page 72 of the SOER: “Unfortunately, our streams are currently degraded to the point where 73.5% of the monitored stream miles are not meeting their designated use and during fiscal year 20032004, only 33% were suitable for prolonged human contact based on bacteria concentrations.” 4. Policy 1.a. page 7 Citizen Comment: At one of the last meetings staff changed the phrase ‘natural resources’ to ‘natural features’. The 2nd paragraph missed one of these changes. Staff Response: Staff supports making the change requested. 2 5. Policy 3.a. Page 11 Citizen Comment: The policy statement needs to read: Enable site designs and construction projects that: 1) facilitate the use of alternative modes of transportation; and the reduction of 2) reduce ground level temperatures; 3) minimize impacts to natural environment; 4) reduce the amount and improve the quality of stormwater run-off; and /or 5) use water efficiently. Staff Response: Staff supports making the change requested with the exception that “and/or” should remain as “and” since we believe this was the intent of the discussion during the policy development process. Comments #6 – 12 are in reference to Appendix 2.b – Implementation Tools. Staff offers the following general response to these comments: The information in Appendix 2.b is not intended to become City policy, rather, it is meant to provide a general guide as to the types of tasks staff will likely be undertaking to implement the Environment Policies. It is not intended as a comprehensive list of implementation strategies. An interdepartmental/interagency staff team is continuing to work on more detailed implementation tasks which will be incorporated into future work programs of various departments. 6. Appendix 2.b Implementation Tools -Environment Citizen Comment: Research, Data and Analysis: page 14 Bullets 2 & 3 (creating a user-friendly guide and developing checklist to determine environmental significance) should be deleted these are not necessary to meet the Guiding Principle (Page 6) Staff Response: The guide and checklist are intended as simple tools for staff to help us more efficiently and consistently implement the policies. If these tools are not appropriate, this reference can be deleted in the document without altering the policy direction. 7. Add another bullet to implement policy goals 2 (b) and (e): Citizen Comment: “Develop a list of roads/walkways/ pedestrian ways that could be extended to provide additional connectivity between land uses either by extension of the pavement or by providing pedestrian or bicycle connections. Prioritize and incorporate into the capital needs assessment process” Staff Response: Staff supports making a change and can add a reference to the text if needed without altering the policy direction. The following language is suggested for such a reference: As part of the City's Connectivity Program, the City will continue to develop and refine a list of roads/walkways/ pedestrian ways that could be extended to provide additional connectivity between land uses either by extension of the pavement or by providing pedestrian or bicycle connections. This is a dynamic list that will continue to be prioritized and incorporated into the capital needs assessment process to complement the new connections being provided through the development process. 8. Information and Education: page 14 Citizen Comment: Bullet 2 should be changed to read (additions noted): Seek opportunities to educate staff and elected/appointed officials on environmental impacts and benefits related to land development and redevelopment. Staff Response: Staff supports making this change. 3 9. 3rd bullet: “providing information on costs and benefits….” Citizen Comment: Can not be directly read from policy 1 (d) and it is worded so broadly that it does not appear to provide enough direction to be measurable and achievable. It should be deleted. Staff Response: An example of the type of information to which staff is referring is the recently completed cost analysis for the Post Construction Controls Ordinance. 10. Rezoning and Subdivision Process Citizen Comment: Last bullet top of page 15 should be changed to read: “Fully consider the environmental impacts when assessing rezoning development proposals. In particular, consider the existing environmental opportunities and constraints when evaluating the type, intensity and form of the land uses in a rezoning development proposal.” [NOTE: Development, by State law, must be evaluated according to the Ordinances in place, not by opportunities and constraints] Staff Response: Staff provides direction and guidance on various types of development proposals in addition to those that are part of a rezoning petition. 11. Ordinance Changes page 15 Citizen Comment: 1st bullet should be changed to read: After review, identify add language to in zoning and subdivision ordinances that conflicts or impedes these goals then to help minimize impacts to environmentally sensitive area delete, modify or add language to remove or minimize the negative environmental effects of competing interests in the current regulations Staff Response: Any zoning or subdivision text amendments would occur after considerable review, and with Council direction and approval and significant public involvement. 12. 2nd bullet should be changed to read: Citizen Comment: Review the zoning ordinance to enable “small-scale” mixed-use development and to enhance the ability to implement area plan recommendations (particularly recommendations for mixed use land uses) and to enable mixed / multi-use development on adjacent parcels in appropriate locations [This change reflects policy 2b] Staff Response: Staff supports making this change. 4 General Development Policies: Draft Environment Chapter Charlotte City Council Environment Committee Discussion At the September 17, 2007 Environment Committee meeting, Committee members asked staff for more information on two concerns: 1) consistency between GDP-Environment, Urban Street Design Guidelines and Post Construction Controls Ordinance; and 2) how the policies will be implemented. Information on each of these concerns is provided below: I. Consistency In response to concerns raised by the Chamber’s Land Use Committee in late 2005, staff reviewed the draft GDP-Environment, Post Construction Controls Ordinance (PCCO) and Urban Street Design Guidelines (USDG) to determine if there were any consistency issues that needed to be addressed. Staff does not believe that there are inconsistencies between the GDP-E and these initiatives. Below is the list of potential concerns that were identified and how they are addressed: 1. Streets in environmentally sensitive areas: The USDG are not “one-size-fits-all.” The street network density and cross-sections in the USDG provide flexibility in that they respond to the adjacent land uses and their intensity. Therefore, if the development is appropriate for an environmentally sensitive area, the streets as per the USDG would be designed accordingly. 2. Water quality impacts of stream crossings associated with the USDG: The draft USDG provide flexibility in providing creek crossings so that crossings can be spaced at greater intervals if needed due to environmental constraints. (See pages 64 and 65 of the draft USDG) Additionally, staff is working on defining ways to further mitigate stream crossing such as best design options for culverts and bridges, cross-sections on creek crossings, etc. 3. Costs associated with PCCO for redevelopment and infill projects: High priority redevelopment and infill areas (transit station areas and distressed business districts) that don’t increase impervious area are allowed by right to forego the requirements of the PCCO except for peak and volume control, provided that a mitigation fee is paid. Lowering the requirements for these areas, therefore, helps to reduce costs and makes redevelopment more competitive, complementing the GDP-E. Staff is also recommending that the PCCO include flexibility options that could further reduce the costs of infill development. 4. Balancing “competing” interests: The draft GDP-Environment clearly recognize that protection of the environment must be balanced with other goals and objectives. The GDP-E provide guidance to ensure that minimizing environmental impacts is part of the evaluation. II. Implementation The draft document includes an appendix that outlines strategies to help guide staff work in implementing the Environment policies once they are adopted. Some of the strategies will 1 require future City Council direction and approval, particularly those items suggesting changes to existing ordinances and regulations. Such changes will also require additional public input and will typically involve stakeholder group review. Additionally, the interdepartmental/agency staff team that assisted in developing the policies continues to work to more specifically identify, prioritize and carry out projects and initiatives that will help to implement each of the policies. Once the policies are adopted, staff will complete development of a detailed matrix of implementation strategies which assigns lead agencies and time frames for completion. The intent is for this matrix to be updated periodically to reflect progress and to make any necessary additions/changes based on changing conditions. 2 General Development Policies – Environment: Final Survey Results As part of the public review process for the General Development Policies – Environment, the Planning Department posted a survey on-line to gather citizen input on the draft policies. In addition to being available on-line for approximately 3 weeks in September, 2007, the survey was administered at the September 12, 2007 public meeting. Respondents were asked to what degree they agreed or disagreed with each of the policy statements. A total of 124 people responded to the survey. The results are summarized in the table below. Additional tables are also attached with the complete survey responses.
