Work Session Minutes of the Town of Cary, NC

Conservation Residential Overlay District and Cluster Option

Conference Room 10035 , 316 N. Academy St. , Cary

August 7, 2007

 

 

Present:  Mayor Ernie McAlister, Mayor Pro Tem Jack Smith, Council Members Erv Portman and Nels Roseland

 

Mayor McAlister called the meeting to order at 4:37 p.m.

 

Absent:  Council Members Marla Dorrel and Jennifer Robinson

 

Council member Julie Robison arrived late and her arrival is noted in the minutes.

Ricky Barker of the Planning Department stated that the ordinance amendments for the Conservation Residential Overlay District and Cluster Development Option were removed from the Round 8 LDO because they needed to be further studied.  Staff has been working with the development community, received feedback from the Planning and Development Committee, and then met with council members to receive more solid direction.  (Staff’s PowerPoint Presentation is attached to and incorporated in these minutes as Exhibit A.)

 

Mrs. Robison arrived at this point in the meeting at 4:43 p.m.

 

Mr. Barker stated that open space subdivisions are not new to Cary .   Lochmere Highlands and Kildaire Farm developments are examples of where there was some open space design.  

 

Mr. Portman said that he likes the concept that the greater percentage of buildable land set aside by a developer the greater incentive they receive.  He said that would align the public and private interests and the developer can get a higher density for conserving more.  He asked about having a conservation incentive that can be applied throughout the Town and provide a density bonus based upon the higher percentage of conserved land.  Mr. Barker said that for each one percent more open space they would get three percent more lots. 

 

Mayor McAlister said integrating the open space into a development makes more sense and they need to determine how to promote that alternative.  Mr. Barker said the alternative takes some of the lots out to provide more of an open feel.

 

Mrs. Robison said they need to either make the modification towards the alternative in terms of the amendment to the ordinance or, if there is a legal problem, then create other incentives to go back to building in keeping with Cary ’s character.  She said a question is whether the developments are allowed to mass grade.  Mr. Barker said one of the alternatives is to reduce clearing on lots and ridges on roadways to address those issues.

 

Mr. Portman said that the incentives are almost a multiplier of 10x, in keeping with the current ordinance.  He said that the concept is clear; they just have the wrong multiplier.  He said council wants to provide an incentive for some larger lots that would be more valuable with more open space and more profitable to develop.  He likes the idea of agreeing on a ratio and then letting the developer ask for the incentive. 

 

Mayor McAlister asked if there were any particular ratio breaking points that the developers thought would make it worthwhile for them to consider.  Mr. Barker said the proposal will be presented to the developer focus group after staff receives direction from council.  Mayor McAlister said that they need to hear from the developer focus group to determine if it’s worth pursuing. 

 

Mayor McAlister asked what can be done for the connectivity and integration of the open space. Mr. Barker said they would need to set criteria for open space.

 

Mayor Pro Tem Smith said that he would like to get away from the concept of ranges.  Mrs. Robison agreed.  She said the market will consume as much house on as little available land as is allowed unless council enforces an alternative based in actual requirement.

 

Mr. Portman said council is trying to create an incentive ordinance to save open space.  He said the current 1 to 9 percent ratio is counter to what they are trying to achieve. He said that the 1 to 5 percent and 1 to 3 percent ratios are more favorable. 

 

Mayor McAlister asked council if they agreed to take the 1 to 9 percent ratio off and move forward to the developer focus group with the other two alternatives.  All of the council members concurred. 

 

Mr. Roseland said they need to be more flexible on the sidewalk issues as long as they meet or exceed the standards.  Mrs. Robison said they need to start dealing on a systematic basis with stormwater management.  Mr. Barker said that is covered later in the presentation.

 

Streetscape Alternatives 

 

Mr. Portman said he would lean toward the developer’s option to increase width as long as it’s opaque, and techniques are used to reduce views from the road.  It keeps connectivity of open space.  He said that kind of an approach would be broad brushed and portrays the classic views of Cary .  Mayor McAlister said that option comes across as more flexible. 

 

Jeff Ulma of the Planning Department stated that the objectives they are trying to accomplish add to the complexity on all of this—low density, rural, protect open space, minimum lot sizes, maximum density; all of the parameters are getting at that complexity and at the view from the public realm. 

 

Mr. Roseland liked the option to increase width with opaque and other techniques as well as requiring deeper streetscapes at entrances to subdivision.  Mr. Portman said the big issue is to get developers to conserve open space.  He said they can’t go below the minimums and the Town would still state the requirements.  He said that council shouldn’t be overly restrictive because he believes that developers will try to create good, high end, attractive communities.  Mayor Pro Tem Smith said the minimum standard is not the product Council wants. 

 

Mrs. Robison said they shouldn’t base the alternatives conceptually on one single development product.  She said the projects that have come before council have not protected enough of the streetscape entrances and leaving it at the developers’ option guarantees that they may or may not look at it. 

 

Mayor McAlister suggested moving forward with the top two options to the developer focus group for feedback—require 1.5 times the width, then provide other open space, and required deeper streetscapes at entrances to subdivisions.  Mr. Portman didn’t agree.  He asked if using the overlay automatically comes to council.  Mr. Barker replied that it does until they get the ordinance fixed; once the ordinance is fixed it goes back to administrative approval. 

 

Mr. Roseland said he would like to provide the flexibility of the developer’s option.  Mr. Portman agreed.  Mr. Barker said there would be criteria set. 

 

Mayor McAlister said he is hearing that council would like to keep all of the options available to receive feedback from the developer focus group.  Mayor Pro Tem Smith, Mr. Roseland and Mr. Portman agreed; Mrs. Robison disagreed.

 

Open Space Criteria

 

Mr. Portman said it was stated upfront that the concept only applies to buildable land, and that credit isn’t given for the stream buffers or the required street frontage.  Mr. Barker said it gets back to requiring that open space be at least 50 feet wide for integration or that the majority of lots are adjacent to open space. 

 

Mayor McAlister said that is achieved from criteria for integrating open space gives.  He said once they do that it will determine whether to move forward.  Mr. Portman and Mr. Roseland agreed.

 

Mrs. Robison asked about open space that is not developable or not accessible to residents.  Mr. Barker said there wouldn’t be any credits or incentives.  Mrs. Robison asked if the developer can still have undevelopable open space that’s not accessible to residents.  Mayor McAlister said yes.  They just wouldn’t get any benefit of credits or incentives. 

 

Mrs. Robison asked if anything is being done to make the undevelopable land accessible.  Mr. Ulma said it would be difficult to get even a greenway trail if the terrain is steep.  Mr. Barker said with the travels and sidewalks there may be a criteria that all of the open space needs to be accessible through a system of greenways and trails, which would get at that point as long as there weren’t any topography issues. 

 

Mr. Portman said an unintended consequence is that there is a lot of land not buildable in certain areas, which under the ordinance becomes an incentive to buy the land because the area that’s not buildable gives you credit toward higher density.  Mr. Barker said staff will look into that.

 

Secondary System of Greenways

 

Mrs. Robison asked for clarity.  Mr. Barker said that the secondary system of greenways is the private circulation of trails that eventually lead to public primary greenways. 

 

Mrs. Robison asked if there would be optional greenways connecting to the public greenways.  Mr. Barker said that is the purpose.  He said it’s also to put in trails that access the extra green open space and provide opportunities for residents to feel like they are in a conservation overlay. 

 

Mrs. Robison asked if the greenways would serve as pedestrian access to move around.  Mr. Barker responded yes.  Mrs. Robison said that according to our own regulations the greenways are not usable after dusk and there are obvious safety issues related to that.

 

Mr. Roseland said it’s about pedestrian accessibility and mobility and he recommends flexibility.  The plans have to have a good pedestrian circulation element.  Mr. Ulma said that the intent was that in creating and maintaining rural character you don’t’ see sidewalks in the country. 

 

Mayor McAlister said that the system should allow a combination of sidewalks and secondary greenways ensuring that open space is accessible through trails.  Council members concurred.

 

Curb and Gutter

 

Mr. Barker said that staff is okay with using curb and gutter as long as it meets the low impact design requirements. 

 

Mr. Portman asked how that would be done and whether a key feature of low impact design was a swale.  Tom Horstman of the Engineering Department said that you can have low impact designs for curb and gutter.  Instead of having storm drains you would have turnouts on the curb and gutter which would then go to a swale system.  He said that you can have the groundwater recharge that you get from the swales system and also have curb and gutter. 

 

Mr. Portman asked about curb and gutter running to a storm sewer.  Mr. Horstman said you want to try to eliminate the storm sewer because there’s no infiltration when there’s a concrete pipe. 

 

Council members liked the options provided.

 

Low Impact Design Options

 

Mr. Roseland said that he doesn’t like the massive sweep of everything inside of a site.  Bonus density units should only be given if minimizing the grading.

 

Mr. Barker asked if staff should still pursue the low impact deign.  Mrs. Robison said yes.  Mr. Roseland said he is open to flexibility as long as the Town’s minimum standards are exceeded.  Mayor Pro Tem Smith doesn’t want to incentivise mass grading.  Mr. Barker said it seems like they have agreement on requiring lot clearing limits and roads on ridges to the extent practical. 

 

Mr. Roseland asked which option equals less nitrogen in Jordan Lake .  Mr. Ulma said those requirements have to be met regardless.  Mr. Barker said swales have been used ever since the Town has had stormwater protection measures.  Mr. Horstman said with the current requirements they are doing almost low impact development.  He said if developers come in and meet all of the requirements and then use the swale system they are doing LID for all practical purposes, which is going above and beyond the Town’s requirements.

 

Mr. Roseland asked if the same amount of impervious surface was being required on the engineering street standards.  Mr. Barker said the Town meets the rural road standards for the main roads.  Mr. Ulma added that internal subdivision streets are the same as the current standard; it hasn’t been changed or altered.

 

Mayor McAlister said the top two options seem acceptable.  Council members agreed.

 

Cluster Ordinance

 

Mr. Barker stated that the current cluster regulations have been in effect for well over 15 years.  He doesn’t remember anyone using them. 

 

Mr. Portman suggested using the same percentage approach as in conservation overlay.  Mr. Barker said the cluster is an option within districts so staff would have to craft it to blend. 

 

Mrs. Robison suggested adopting the percentages as an overall approach.  Mr. Barker said Town wide they are talking about a lot of infill.  He said it would open the door for allowing it by right and it would only go down 15 percent. 

 

Mayor Pro Tem Smith said he is okay with adding additional restrictions to creates checks and balances.

 

Mr. Portman asked about not exceeding 3.6 units per acre.  Mr. Barker said it is an example for R-12 and it couldn’t be exceeded from a gross density standpoint.  Mr. Portman asked about the incentive.  Mr. Barker said most properties on a conventional R-12 subdivision won’t achieve 3.6 because of roads, stream buffers, etc.  Mayor McAlister said setting the bar higher makes sense, even if it’s not as strong an incentive to go this way.

 

Mr. Roseland said if there is additional open space which has a feature that can bring them together with incentives then that should be done.  Mr. Barker said within open space they can have some type of feature instead of just a trail.  Mr. Roseland said he would like it to have something that gives a sense of community. 

 

Mrs. Robison said that developers who have experience with Cary will come in with projects that have like lot sizes.  She said council doesn’t have to make it a mandate. 

 

Mr. Portman is concerned about putting in hard numbers which precludes the concept council is trying to achieve.  He asked about the incentive for the cluster ordinance.  Mr. Barker said you may be able to get 3 units per acre in an R‑12 subdivision; the ordinance gives up to 3.6 acres.  He said staff will still use percentages but it will be capped.

 

Next Steps

 

Mayor McAlister asked that council be notified once the developer focus group meeting is scheduled in the event council members want to attend.  

 

Mayor McAlister adjourned the meeting at 6:03 p.m.
