changing the character of the fence on the site. Originally, the intention was to deter both human and
pet encroachment into the wetlands. However, with the pet restriction in place, staff would like to
explore the removal of the metal rail fence and instead suggest the installation of a split -rail or similar
type fence that would still deter humans but facilitate wildlife movement throughout the site to a higher
degree than the metal rail fence would. To discourage social trails through the wetlands, signs installed
along the fence could remind those passing by that the area has been protected for its natural features
to encourage folks to stay out of the wetlands.

Issue: 12/07/2011: Based on today's staff review, we believe the fence design is resolved. However, a couple
of notes were that a fence in between 4 and 4.5' height is acceptable, with a 6" gap at the bottom of the
fence. A heavier gauge wire, or one similar to that at the Gardens on Spring Creek, is requested.
12/06/2011: From discussions with the applicants and several neighbors, many felt that a wood -based
fence would not be compatible with the project's modern architecture. However, the revised design in
staffs opinion, is less desirable than the originally approved metal picket fence. Based on a brief
discussion with the applicant yesterday, staff is now trying to work with Campus Crest and their
consultants to modify the originally proposed, metal picket fence from 6' in height down to 4' in height.
This would provide a fence that is compatible with the site's architecture, still provides a significant
discouragement to residents and passers-by to enter into the Natural Habitat Buffer Zone, while
increasing the ability of wildlife to jump over the fence as needed.
10/25/2011: In light of the pet restriction being placed on the project, City Staff would like to discuss

ascertain how the structural integrity of the sidewalk/ramp itself is maintained and verify whether a
tripping concern might exist with a drop off the sidewalk. Perhaps a curb up against the sidewalk/ramp
should be considered if there's the potential of a drop off the sidewalk is of potential.
6) We're wanting to ensure that the sidewalk chase in the rain garden area is built with the additional 6
inches of length on either side with transitioned widened walk in general accordance with D-1013
(provided in the original set but removed in the revisions).
7) Continuing on the culvert design from #6 above, the opening being less than 2 feet would not be
objected by Engineering is satisfactory with Stormwater. At the November meeting it was indicated that
the use of a decorative metal plate could potentially be used. In looking at the information now provided,
we'd like to verify if this plate is in use somewhere and/or if a sample of this can be provided. Of
question is whether it can be viewed that the texture of this plate provides an equal amount of traction
as compared to the diamond plate. Are the decorative leaves in the detail indicative of "holes" in the
plate?
8)Please provide cross-section detail of both the overflow control weir and curb opening for the rain
gardens. We're wanting to ascertain what occurs "behind" the curb section with the flow of water taking
place. For the curb opening, it should specify that the gutter maintain the 6" thickness at the opening.

Issue: 12/07/2011: We need construction detail information on the subdrain "risers" which are presumably
different than a cleanout, as this doesn't appear to be on the plan set. Is it intended that these risers are

cleanouts? Where is riser 4 intended to be located in relation to the crosspan if it is brought to finish

Issue: 12/07/2011: The revised sheets do provide a detail for the enhanced crosswalks proposed on both sides
of the Rolland Moore Drive/Native Plant Way indicating that these are both proposed to be concrete.
With this in mind I believe it's very appropriate that the City require the entire intersection to be done in
concrete from crosswalk to crosswalk such that asphalt/concrete/asphalt/concrete/asphalt switching of
interface is eliminated in such a relatively short area. Provide jointing pattern detail with this concrete
intersection.

that said though, the amount of cross slope here I still view as a concern in terms of ensuring that
drainage flows off the pavement and doesn't puddle here. I think options should be explored such as
offsetting the crown to the south and east in order to steepen up this area, as there could be some
"room to play" with the cross slopes on the outside curve. Please provide some cross slope percent
information on the inside turn.

Initial Date: 12/07/2011 Issue ID: 21 Topic: Construction Drawings Round: 2 Status: Active
Issue: 12/07/2011: With the rain garden design information now provided, we have the following
thoughts/concerns:
1) The structural stability of the system is still in question in our view, with whether the proposal
demonstrates that it would not compromise the surrounding roadway and sidewalk system and whether
the rain garden system itself could be impacted from foot traffic, etc. We can cite a structural slope
stability report from a geotech engineer on a previous project where slopes of a lesser steepness was
proposed, we believe this type of analysis is needed and should take into account much of the detail in
the following additional comments.
2) With the previous comment in mind, and with the proposal that cobble is intended to provide stability
adjacent to sidewalk and curb and gutter grades, the cross sections should really show the cobble
information with its intention of providing structural stability. In addition the cobble information should be
described in the bioretention sand media narrative detail.
3) Indicate a minimum distance in which a level run of compacted subgrade up against the curb and
gutter/sidewalk is intended to be.
4) Cross-section typical information should be provided where the underdrain is not under a rain garden
but between two rain gardens (under driveways/streets). Is the pipe in this case changed from perforated
to solid? How does (or just does) the bedding transition from a rain garden to a non -rain garden section?
5) We'd like to see a rain garden typical profile that goes through the sidewalk/access ramps to

indication of underdrain (typical depth?), bedding material/wrap around the underdrain, etc.
- Some structural analysis is needed to indicate how the structural integrity of the roadway and curb and
gutter section is maintained where Rolland Moore Drive abuts the rain garden. There is the potential
concern that the soil needed to effectively allow the necessary percolation for the success of the rain
garden does not provide sufficient integrity to the abutting curb and gutter and roadway section. There
may need to be the exploration of either the use of more native soil to provide sufficient stabilization
abutting the public infrastructure that then slopes off to the different media specific to the rain gardens,
and/or the use of a concrete wall extending below the curb and gutter of the neckdown to provide that
support.
- Indicate how the rain garden design is intended to be perpetuated for drainage where the rain garden is
interrupted by driveways. There is a concern on the premise of flows leaving a rain garden, draining
across a driveway and then reentering a rain garden on the other side of the driveway. If flows leave the
street section into a rain garden, the flows shouldn't then re-enter the street system and then move to a
successive rain garden.
- It would be beneficial to provide some documentation that the plant species specified in the
landscaping plan for the rain garden areas were viewed as appropriate for the rain garden design,
function and use.
- Additional review and comment may be needed upon providing the additional information. It would be of
benefit if a rain garden design/report was provided addressing the items noted above with the report
being signed and stamped by the engineer.
Engineering Development Review's Unresolved Issues:

Initial Date: 10/26/2011 Issue ID: 10 Topic: Construction Drawings Round: 1 ' Status: Active
Issue: 12/07/2011: The placement of the sidewalk crossing across the street appears to resolve the issue.
With that though, what does the 2.84% flowline profile across the north side of this intersection
represent (on sheet R3)? It appears to imply that a cross plan occurs here, but that doesn't seem to be
the case. Please ensure that flowline representations along the curb returns are represented between
sheet R3 and R6.
10/26/2011: The northeast corner of Perennial Lane and Rolland Moore Drive shows a 7.1 % grade along
the flowline of the curb return on the plan and profile sheets. Another steep grade along the flowline of
curb return is at the southwest corner of Centre Avenue and Rolland Moore Drive at about 6.1 % These
steeper grades around the curb returns along the flowline need to be looked at and reduced in some
manner. There are concerns of how steep the access ramp cross slopes presumably are for pedestrians
entering the intersections. Additionally, does this introduce the possibility that flows from the street
won't actually want to remain in the flowline of the street but will want to enter the access ramp/sidewalk
system itself? Spot elevations and longitudinal grade information along the sidewalks/access ramps at
these steeper intersections should be provided to demonstrate that flows along the gutter are
maintained. Perhaps roadway crowns should be flattened to make the amount of grade change along
the flowlines less prominent in these instances.

Engineering Development Review's Unresolved Issues:
Made By: Marc Virata
Initial Date: 10/26/2011 Issue ID: 1 Topic: Landscape Plans Round: 1 Status: Active
Issue: 12/07/2011: I'm understanding that the native grass proposal on the east side of the maintenance
driveway for the Gardens at Spring Creek isn't desired by Michelle Provaznik, the Director of the
Gardens at Spring Creek -- a continuation of flower beds is desired instead. Please coordinate with
Michelle to ensure that the information shown on the landscaping plan is acceptable with Michelle. It
would seem that additional area could be shown on 15 of the landscape plan to reflect the limits of
where new landscaping (east of the driveway) is intending to end.
10/26/2011: The landscape plan needs to indicate the landscaping that will be done by the development
resulting from the removal of the existing Rolland Moore Drive street and temporary turnaround. The site
and landscape plan documents don't show this area being impacted by the development.
Initial Date: 10/26/2011 Issue ID: 4 Topic: General Round: 1 Status: Active
Issue: 12/07/2011: A redline from Technical Services was generated but may have not been communicated
back from the previous round of review. The concern being that "Center" at the end of the third line of the
third paragraph should be "Centre".
10/26/2011: The sight distance easement legal description is being reviewed by Technical Services,
note the need to change "site" to "sight".

Issue: 12/07/2011: see Comment 21 (tried to provide here but a maximum size was reached).
10/26/2011: The rain garden concept needs to have additional design information provided in the
construction plan set for final plan review. City staff with representatives of both Engineering and
Stormwater had the opportunity to meet and review the final plan submittal and identified key
considerations and issues. Among the information needed and concerns with the information provided
thus far:
- Indicate locations on the Rolland Moore Drive plan and profile views where the openings for the rain
gardens are intended.
- Provide a detail on how the curb and gutter section transitions to and from the opening for the rain
gardens.
- The flowline grade around the neckdowns past where the opening for the rain gardens occurs must
remain on -grade. There are several instances where the grade goes negative past the openings which is
of concern. The City requires that positive grade be maintained around the neckdowns to minimize the
amount of retrofit needed should the rain garden use be eliminated and drainage is perpetuated around
the neckdowns along the flowline.
- Provide cross -sectional information of the rain gardens, including soil media information and depth,

Issue: 12/09/2011: Craig Foreman of Parks Planning has indicated that his concerns have been given to and
routed through Marc Virata of the Engineering Department.
10/25/2011: Craig Foreman of the Parks Planning Department offered the following comments:
a. This development is responsible for a repay for the construction of Rolland Moore Drive along the
south side of the Gardens on Spring Creek, a City -owned facility.
b. A portion of the west end of the existing Rolland Moore Drive adjacent
to the Gardens on Spring Creek will be demolished if this project is approved. Once any existing curb,
gutter and pavement is removed the developer of The Grove would be responsible for
reclaiming/restoring
that area by putting it back into native/natural grasses and/or landscaping.
