Sundstone Gondominium Assoc. 2-Lot SP.
Permit Application #: PLN20190036
DearAmber,
This letter is intended to summarize the changes made to the Site Plan and Preliminary
Engineering package submitted/reviewed for this project based on comments provided by the
City in a letter dated August 22,2A19. This letter has been laid oulformatted to try and match
the letter provided by the City for ease of understanding.
1. The Site Plan will be updated by the Project Surveyor and will be addressed under a
separate letter.
2. Stormwater Engineering Comments will be addressed below.
3. Engineering Comments from JoAnne Zulauf will also be addressed below.
STORMWATER ENGINEERING COMMENTS - ZACH RICHARDSON
1. A draináge report along with the geotechnical study for this project is included with the
resubmittal package.
2. Each LID BMP feasibility is discussed in the included drainage report and infiltration
feasibility is determined in the geotechnical study.
3. Driveway dispersion is provided along the north side of the surface.
4. The retrôfít requirement is now being met with a level spreader for existing roof runoff to be
located along the east side of future Lot2.
5. Discussion of tne dispersion requirements are in the report and detailed design information
will be inoluded in the future full construction plans
6. Storm line shown and no conflicts were found with the new services.
ENGINEERING COMMENTS - JoANNE ZULAUF
GENERAL
1. The grades ón the site make use of the existíng access easement to serve the new SFR
in-feasible. The proposed access point for the future SFR on Lot 2 was discussed during
the pre-app and Staff agreed that the proposed location was the best option available for
Lot 2.

2.
a. Noted.
b. During the pre-app no changes to the existing frontage improvements were
commented on that would be required. There is a large cut section along a portion of
the frontage south of the existing condominium and parking. Moving the existing
sidewalk to the north to accommodate a 4-foot wide landscape strip would be very
costly and impact other utility easements that are in the area of the frontage to be
dedicated to the City. Street trees could be provided behind the existing sidewalk
without impacting the existing grades in those areas of concern. Street trees can be
shown behind walk once this issue is resolved. ln addition, the landscaping directly
behind the sidewalk is in very good condition and of high quality so removing that
vegetation to relocate the sidewalk seems like it would be going against the intent of
the code.
c.Note added to plan.
3. Driveway alignment straightened untilfully on the property.
UTILITIES
1. Approx. ie for side sewer at house, prop. line and connection to main added to plan.
2. Existing utility service information added to plans.
3. Water service line called out as 1.5"
Thank you for taking the time to review the revised plans for this project. Please feel free to
contact me with any questions you may have.
