2018-20_788 Grant Pl_Disposition Packet N O T I C E FINDINGS AND DECISION OF THE CITY OF BOULDER BOARD OF ZONING ADJUSTMENT DISPOSITION OF ZONING CASE DOCKET NUMBER 2018-20 CONCERNING THE APPLICATION FOR A VARIANCE OF THE SETBACK REQUIREMENTS OF SECTION 9- 7-1, B.R.C. 1981 AT 788 GRANT PLACE OF STVE GOLLOB, WHOSE MAILING ADDRESS IS 788 GRANT PLACE, BOULDER, COLORADO 80301. On September 13, 2018, the City of Boulder Board of Zoning Adjustment, a quorum being present, held a public hearing, after giving notice as required by law, on the application for the following variance: As part of a proposal to remove a portion of an existing upper level roof and walls within the front (west) yard setback – to be replaced with a rooftop deck and railings constructed in the same location - as well as add a two- story addition onto a portion of the interior side (south) and rear (east) sides of the existing nonstandard house, the applicant is requesting a variance to the minimum front yard and combined side yard setback requirements of the RL-1 zoning district. Only the first story (lower level) of the rear addition will encroach into the required side yard setback with the second story (upper level) stepped back and to the north, meeting setback requirements. For the existing upper story modification and addition of a rooftop deck with railings, the resulting west yard setback will be approximately 18.5 feet where 25 feet is required and approximately 18.5 feet exits today. For the new rear addition, the resulting south yard setback will be approximately 7 feet where 13.8 feet is required and approximately 10.3 feet exists today. Section of the Land Use Code to be modified: Section 9-7-1, BRC 1981. Based on our field investigation and the relevant testimony, exhibits, and other evidence introduced at the hearing, and in accordance with the applicable provisions of the Boulder Revised Code, 1981, we find by a preponderance of the evidence that the criteria for granting a variance have been met, and grant the variance as requested: This variance is limited to the use and structure for which it was requested, including the location on the lot and maximum height, as approved by the Board of Zoning Adjustment. This variance was approved by the vote of 5-0. EXECUTED this 13th day of September 2018, effective as of, September 13, 2018. Michael Hirsch, Presiding Officer of the Board at the Meeting By: ____________ ____________________________ Robbie Wyler, Secretary to the Board of Zoning Adjustment This decision constitutes a final decision as of the date of the hearing at which it was reached. If a variance was granted, the variance expires within 180 (one hundred eighty) days from the date on which it were granted unless a building permit for such variance is applied for within such period.

We are hopeful that we will be able to at last make the changes we need that will allow our home to realize a level of functionality and quality that we have dreamt about since we purchased this formerly abused property with odd dimensions, poorly laid-out spaces and inefficient circulation patterns. Since childhood, I have appreciated everything that Boulder offers and stands-for. The work, savings, and logistics Pam and I faced to find our home required extraordinary alignment of many things and a little luck. This adds to our deep appreciation of our home and community. We do not take anything lightly when it comes to this long- awaited project and seek your help. We enjoy cooking and entertaining family and friends. However, with the poorly located small kitchen and odd relationship to adjacent space, there is no good internal circulation path making this core of our home crowded and hot for more than two or three people. BOZA Disposition of Approval Page 5 of 22 Page 2 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & We want to create a more usable kitchen by relocating to another room where we need a small amount of expansion for this to work best. Our daily routine in the current bedroom and bathroom requires that we squeeze past one another to use the bathroom and wait to take turns due to the odd layout and space. My office is in the home and currently serves as both office and closet space. Pam’s “closet” space is in the hallway outside of the small “master” bathroom. We extensively use the deck space at the rear of the home. Sacrificing any of that space would not only have negative implications on our lifestyle and practical purposes, but would increase the visual bulk/mass. The limited square footage we are seeking to add in the rear/side is critical to the larger project’s key functional underpinnings and would be unnoticeable to passersby. The current home’s configuration presents many challenges on every level caused by the odd floorplan and poor use of space. The exterior also needs a new approach and updating to reflect the quality of what we seek to accomplish and contribute to the quality of our special neighborhood. Warmly, Steven Gollob and Pam Mares 788 Grant Place The history of the residence The home at 788 Grant Place was originally constructed at the turn of the last century – roughly 1930 – replacing a home that had been constructed in 1914. The small home was constructed of stone masonry exterior walls with a wood framed roof and exposed rafters. Initially, the northwest corner of the home was anchored with a covered porch and likely an open railing. The porch has since been enclosed with a low stone wall, concrete sills and windows. As originally constructed, the home contained approximately 1,500 SF of living space set atop a crawl space. A detached garage was constructed east of the home adjacent to the alley with similar design characteristics of stone, low pitched frame roof clad with shingles. BOZA Disposition of Approval Page 6 of 22 Page 3 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & In the late 1980’s, a partial first floor and second story and loft addition was placed atop the existing home. The first floor addition extended the footprint of the home approximately 12’ to the east, and was raised above grade on pier foundations. The second story covered a fair bit of the original home and the first floor addition. A partial third story “loft” rises above a portion of the original structure. The exterior was finished of vertical tongue in groove wood and painted. In creating this addition, a significant amount of volume was added to the existing home, yet the interior spaces remained somewhat small and dysfunctional. For example, the kitchen, located 3 steps above the dining room, is centered in the house, forming a barrier between the interior living spaces, and further. The second floor addition included a master bedroom that is quite isolated, quite dark, and poorly proportioned, with inadequate bathroom and closet space. A second living room space is also located on the second floor, serving little purpose. The loft space – open to the second living room, is difficult to access and for the homeowner is not a practical use of space. Further, in creating this addition, structural loads were placed upon the existing structure that have caused it to begin to fail – as identified by the out-of-level floors and significant cracks developing in the exterior stonework. The current homeowners wish to correct these deficiencies and repair the structure to prevent additional structural deterioration. To do so, we have developed a plan to BOZA Disposition of Approval Page 7 of 22 Page 4 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & create a small addition to the east of the existing residence that would contain the family and entertaining spaces of kitchen, dining, and great room. This proposed first floor addition will include structural elements integrated to alleviate the loads which seem to be causing the failure of the original masonry bearing walls. Atop this first floor addition, revised interior circulation and a small addition will mitigate the issue of lack of adequate space in the master bedroom and provide suitable closet and bathroom facilities. Finally, much of the loft space will be rebuilt as an open roof deck, thus reducing some of the visual mass of the building and providing private outdoor space with stunning flatirons views. The need for a variance The lot at 788 Grant Place is narrow, sloping down from Southwest towards the northeast. Owing to the corner location, the setbacks are substantial and limiting, and the footprint of the original 1930’s home is significantly out of compliance with current zoning regulations. The following is a table showing the required setbacks as defined by current RL1 zoning, and the existing setbacks of the current home onsite, followed by a graphic representation of them: Setbacks Required Existing West (front) 25’ 14.2’ North (side, corner) 12.5’ 1.2’ East (back) 25’ 64.8’ South (side, interior) 13.8’ * 10.3’ * Normally 5’, except for Boulder’s required combined 15’ side setback, and the existing 1.2’ north side setback One can see from the chart above that the home encroaches into all required setbacks except the rear setback towards the east. The graphic illustration below shows the existing first floor plan of the home outlined in red, the detached garage located towards the alley on the east side of the lot, with the gray shaded box defining the area of the site that can be developed by right given the existing building configuration and the required setbacks. BOZA Disposition of Approval Page 8 of 22 Page 5 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & The homeowner’s needs for space In addition to the structural damage caused by the addition in 1988, several functional and size limitations have been identified in the design process which the resulting proposal intends to correct: 1. The home contains only three bedrooms – one on the main floor and two on the upper floor – where the homeowner requires four to meet their needs. 2. The enclosed front porch does not provide useful space and would be opened and restored to original by removal of the glass and stone infill, to once again become an open porch. 3. The kitchen, dining, and entertaining spaces are poorly sized and configured as well as partly located on different floor levels. 4. The existing loft space is only rarely used. 5. The master suite is too small for the owner’s needs, and closet space is severely limited. 6. The master bath is poorly sized and does not contain the owner’s preferred allocation of fixtures. 7. The opportunity to add a rooftop deck that can access the splendid foothills view is available, which would simultaneously reduce some of the building’s mass. 8. The image and proportions of the 1988 addition are not scaled well nor are they overly attractive. 9. Parking in the neighborhood is problematic with the soaring popularity of Chautauqua; the garage itself is too small for the owner’s vehicles, bikes and other stored items, and thus the parking issues in this neighborhood on occasion make it difficult for the homeowners to park near their home. The lot size for this property is 6,249 SF, which is somewhat smaller than normal for the RL1 zone district (7,000 SF minimum). The resulting development constraints due to lot size are 3,330 SF of floor area and 2,280 SF of coverage. The current home and accessory structure contain 2,987 SF of floor area and 1,874 SF of coverage. Further, removal of some existing floor area and coverage is possible by un-enclosing the front porch (137 SF) and removing a portion of the third floor loft space (90 SF). A combination of these strategies provide a suitable amount of space to accomplish the owner’s program within the RL1 zoning regulations constraints. BOZA Disposition of Approval Page 9 of 22 Page 6 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & Scope of Work Our initial goals in this addition project were to keep within the development limits imposed by the setbacks. The space we were considering is shown in red on the plan below. However, all layouts that we tried to integrate were unsuccessful at meeting the owner’s requirements: 1. One of the overbearing issues with the existing floor plan arrangement is that one needs to walk through certain rooms to access the others – i.e. the need to walk through the kitchen to gain access to the dining room and the family room on the east side of the home. Extending the existing footprint further towards the east within the area defined by the setbacks managed to preserve this deficiency. 2. Creating an addition east of the home constrained by the setbacks and providing the appropriate floor area resulted in an extension of the footprint 11’ to the east. This extended addition resulted in loss of a significant portion of the owner’s existing deck, encroached upon the existing sunken garden and hot tub space, and contributed significantly more to the mass of the building. 3. One further important consideration is the structural damage occurring to the outside of the home (blue arrow above). We recognized early on that we are going to need to do a fair bit of foundation work in order to correct and mitigate the future occurrence of this damaged area. As such, it had been in our original intention to construct a portion of the new construction in this area, and thus use the new construction to reinforce the original structure and prevent additional foundation deformation. This damage is occurring on a portion of the building that is positioned within the 13.8’ setback (driven by 1.2’ setback on the north), and thus it would not be possible to use new BOZA Disposition of Approval Page 10 of 22 Page 7 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & construction to bolster the existing in a by-right construction project without first receiving a variance to build within the setback. Moving on from the by-right project, we considered an addition that was justified closer to the existing home and positioned more towards the north and Cascade Ave. This addition would have extended through the regulatory 12.5’ north side property line adjacent to a street setback. Consultation with planning suggested that the 12.5’ setback was more relevant in terms of varying the requirements in that it is considered by all new construction and renovations on corner lots. However, perhaps it would be a useful consideration to encroach into the 13.8’ setback on the south side, which is not regular, but derived by considering the 15’ combined side yard setback. The resulting proposal is shown below: This proposal requires a variance for extending into the 13.8’ side yard setback that is derived from the requirement for a 15’ combined side yard setback. At its nearest position, the addition indicated above is positioned 7’ from the south side interior property line. Although 13.8’ is required due to the face of the north wall being only 1.2’ from the property line, were that not true, the regulatory setback distance would typically have been 5’ from this property line (green dashed line above), and thus this proposed addition is not conformance with code requirements due to the pre-existing north wall construction and the proximity to the north property line. It is also important to recognize that, although this is a two story home, the encroachment into the side yard setback will be confined to the first floor. The second floor would maintain the line of the existing second floor south wall, which BOZA Disposition of Approval Page 11 of 22 Page 8 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & is roughly 15’-4” from the south property line at its nearest position, and thus in compliance with setback regulations. A substantial improvement of this proposed design over the by-right design is the less than 4’ extension into the existing back yard – thus reducing the amount of the owner’s deck that the addition will consume and reducing the proposed expansion into the back yard from 11’ to 4’, significantly reducing the mass of the proposed building. Proportionally, this addition works much better to manage the arrangement of the owner’s space plan and eliminates the interior circulation difficulties that were integral to the by right design. The placement of this addition is directly alongside the portion of the existing residence that is experiencing structural failure due to the improperly designed loading of the 1988 addition. With that in mind, we will be able to utilize the addition to stabilize the original home and extend remedial structural elements from the addition into the existing portion of the home to correct the structural deficiencies and gain control over the deterioration. An observation derived from reviewing the site and survey is the extraordinarily wide tree lawn that is situated north of this home. The distance from the home to the north property line may well be only 1.2’, but the distance from the home to the north sidewalk is 5.4’. Further, owing to the very wide tree lawn along the south side of Cascade, directly north of this home, the distance from the home to the curb on the south of cascade is 24’. We recognize that this is not relevant information for by-right development considerations, but in this variance process, we think that the requirement for wider side yard setbacks facing a street is in place to prevent massing buildings onto corners and may be valuable where the tree lawns are a more typical 5’ – 6’ dimension. The tree lawn north of this site is nearly 15’ wide from the sidewalk to curb. That is an unusual, unique aspect to this lot, and will preserve the openness of the corner very well. In a sense, the large dimension allows the 12.5’ side yard facing a street setback to be realized, even if not from the property line. Articulation of the variance We wish to be granted a variance from the combined side yard setback requirements of the BRC and be allowed to develop a single story addition that extends to approximately 7’-0” from an interior lot line, where 13.8’ is required due to combined side yard setback requirements. BOZA Disposition of Approval Page 12 of 22 Page 9 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & Board of Zoning Adjustments Variance Criteria (1) Physical Conditions or Disability (A) (i) Unusual Physical Conditions There are several unusual physical circumstances associated with this lot: a. The lot is smaller than standard lots in the RL-1 zone district. Minimum size for lots in this zone district is 7,000 SF, whereas this lot is 6,249 SF. This is partly manifested in the more significant constraints imposed upon development on this lot by required building setbacks than may otherwise be experienced by standard sized lots. b. This lot is situated on a corner, which invokes the requirement for a 12.5’ side yard setback from a street. c. An existing home is present and being preserved in this project. The existing home, built well before zoning rules were in effect in Boulder, is positioned 1.2’ from the north side yard property line, creating a distinct difficulty with the addition on the south side of the home, by virtue of the combined side yard setback requiring 15’, and thus 13.8’ is required on the south side. A normal side yard setback requires combined 15’ combined side yard setbacks, but with a minimum of 5’ and not 13.8’ d. The north side of the home is positioned approximately 25’ from the flow line of the curb on Cascade, which creates an extensive tree lawn and eases the concern for building massing near the northwest corner. e. The existing building has received a pop-top in the late 1980’s which appears to be causing structural damage to the existing building through either excessive loads being placed on a foundation not designed as such, or also due to lot drainage issues resulting in differential settlement. The portion of the building that is deforming due to these circumstances is within the south side yard setback. An opportunity to stabilize the structure can be realized by erecting new construction alongside the existing failing construction. f. East of the existing residence is a fairly extensive existing low level deck and excavated lower courtyard containing a hot tub. (B) These conditions do not exist throughout the neighborhood The conditions described above are perhaps not unique but are certainly unusual in the neighborhood and throughout the City as a whole in the RL-1 zone district. (C) Because of such circumstances the property cannot reasonably be developed Although it would be possible to develop the property, such development would require removal of existing improvements that would not be easily or efficiently replaced. Further, the opportunity to utilize the redevelopment to stabilize the BOZA Disposition of Approval Page 13 of 22 Page 10 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & damaged portion of the building would not be possible as the damaged portion of the home is within roughly 4’ within the required side yard setback of 13.8’ (D) Any unnecessary hardship was not created by the applicant This hardship is due to circumstances outside of the control of the existing owner, that being the existing home being constructed within 1.2’ of the north property line. That portion of the building provides the only interior access to the basement storage area, and mechanical equipment and cannot be easily revised. Were that small addition not in place, the remainder of the home, exclusive of the covered front porch, would be situated at approximately 5.3’ from the north property line. The homeowner did not construct the original home as it was built circa 1930. Zoning regulations adopted since that time have brought about the non- conformity. (2) Energy Conservation (A) The variance will permit construction of an addition to a building constructed on or before January 1, 1983 N/A (B) Proposed addition is an integral part of the building N/A (C) The proposed addition will qualify as a “solar energy system” N/A (D) The cost to construct per regulations would be substantially greater than the cost of construction without this variance approval N/A (3) Solar Access (A) The volume of the part of the lot in which buildings may be built per code has been reduced substantially by the provisions of the BRC Section 9-9-17 N/A (B) The proposed building or object will not interfere with the basic solar access protection provided by BRC Section 9-9-17 The small proposed addition will be positioned to the east and south of the main mass of the home and will be significantly lower than the existing home. The lot is situated on a corner with the neighboring residence being nearly 100’ away to the north. There will be no encroachment of solar protections for existing homes by this small proposed addition. BOZA Disposition of Approval Page 14 of 22 Page 11 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & (C) The volume of the proposed building outside of the setback will not exceed the volume that the building has been reduced as a result of provisions of BRC Section 9-9-17 N/A (4) Designated Historic Property The property could be reasonably developed in conformity with provisions of the BRC, but the building has been designated as an individual landmark or recognized as contributing to a designated historic district. Review of an alteration certificate pursuant to Chapter 9-11, “Historic Preservation” of the BRC, the approving authority has found that development in conforming locations on the lot would have an adverse impact upon the historic character of the individual landmark or the contributing building and the historic district (if a district is involved). N/A – the home apparently lacks any contributing aspects as determined by the most recent City of Boulder property landmark survey (5) Requirements for all variances (A) The variance will not alter the essential character of the neighborhood or district in which the lot is located The small proposed addition will not alter the essential character of the neighborhood or district. With the change of siding and proportions – especially reducing the mass of the Southwest corner of the building by carving away some roof and installing instead a guardrail - it may actually become more in keeping with the character of the neighborhood. (B) The variance would not substantially or permanently impair the reasonable use and enjoyment or development of the adjacent property The position for the proposed development occurs towards the east and south. Admittedly, it is moving the mass of the home slightly closer to the home on the south side, but only on the first floor – the second floor remains in the same plane as the existing second floor. This mass is set downhill from the residence located to the south by several feet in elevation, and further is already visually screened for the most part by a tall privacy fence. Additionally, extending towards the east, much of the neighboring residence is garage. This all being considered, there would be no obvious reason why a single story addition would impair the reasonable use and enjoyment of this southern residence. No other homes in the neighborhood would experience any effect from this proposed addition. Images of the aerial view of the site and of the space between this home and the neighboring home to the south follow: BOZA Disposition of Approval Page 15 of 22 Page 12 A r c h i t e c t u r e K y l e C a l l a h a n A s s o c i a t e s & (C) The variance would be the minimum variance that would afford relief and would be the least modification of the applicable provisions of this title This is the least variance that is acceptable to afford relief. It does provide for the improvements to the home that the owners feel necessary to alleviate current issues with the space. (D) The variance would not conflict with the provisions of Section 9-9-17 of the BRC - “Solar Access” There is no conflict with the solar access regulations in the BRC.
